Minimum income and other conditions for this 2026

Let’s clarify the minimum income to file the income tax returnso you can know if you have to do it or not. Because there are some cases in which if your income is not much, you will be exempt from doing it. As usual, if you have collected more than certain amounts During the last tax year, you will have to file the declaration. It is not a fixed amount, because it depends on whether you have only one or more than one payer. Remember that according to the Income calendarthe campaign starts on April 8 Who doesn’t have to pay the rent? We are going to tell you the limits of income from work below which you do not have the obligation to file the Income Tax return, unless it is one of the cases that we will tell you later and which are always obligated. These limits are for those hired as employees. If you have only had one payer: If in total you earned less than 22,000 euros gross per year, you are not obliged to declare the income. If you have had two or more payers: When you have had several payers and the second and remaining one has paid you more than 1,500 euros, the limit for not having the obligation to declare drops to 15,876 euros gross per year. If the second payer or any of the remaining ones has not paid you more than 1,500 euros, then the limit is still 22,000 In addition to these limits, starting with the 2025 Income that we will make in 2026, the obligation to make the income for those who receive non-contributory benefits or subsidies from the SEPE is supplemented. This exception is only if you have no other sources of income such as rents or profits on the stock market, which will force you to account with the Treasury. Other income beyond work In addition to your salary, there are other types of income that may force you to declare or that they can exempt you if you do not exceed certain amounts, as long as one of the previous conditions is not also met. They are the following: Full income from movable capital (dividends, interest on accounts, deposits, investment funds, prizes) subject to withholding or deposit into accounts. The limit below which you do not have to make the declaration is 1,600 eurosand if you exceed it you will have to declare. Imputed real estate income, public aid and subsidies for the purchase of housing must be declared if they exceed the 1,000 euros. Asset losses greater than 500 euros They also require declaration. If you are below these amounts, you will not have the obligation for this reason. Who has an obligation ALWAYS and without exception And just as we have told you what can make you exempt from filing your income tax return, now we will tell you in which cases it will be mandatory do it. They are the following: Self-employed: Any self-employed worker will always have to file an income tax return, regardless of their income level. Minimum Vital Income (IMV): People who receive the Minimum Living Income must always submit the income tax return, even if they do not exceed the general limits. Also the rest of the people in the coexistence unit. Food annuities: Those who receive annuities for food that are not exempt, or when the payer of work income is not obliged to withhold. For example, in the case of separation or divorce, if the child receives maintenance annuities from the parents by virtue of a court decision or the regulatory agreement.

subsidies, taxes and public transport

Were you thinking of getting gas this week? Everything indicates that it is best that you do it as soon as possible. Since last February 28, when the United States attacked Iran, the pieces began to move. Hormuz was put at risk, oil and gas rose and service stations were already beginning to charge more money for a liter of gasoline. Since then, an idea has been floating around: can the Government do something about the rise in gasoline? The facts. Only a few hours had passed since first American bombing when the most cautious began to fill the tanks of their cars. Of course, the fear of a general increase in gasoline was already floating in the air. Just a handful of days later, has been confirmed. And although the average price of gasoline has not yet reached 1.60 euros/liter, a good number of gas stations already show much higher prices. Especially in the big cities and in the big corridorswhere replacement is more common, prices have risen more strongly. A solution? At the moment, the Government has not made major statements about what measures may be applied if the price of fuel becomes too expensive. The Minister of Economy, Carlos Body, for the moment he has limited himself to saying who are considering applying “a shield for our citizens and companies.” The statements do not say much and it has not been clear if it is about trying to lower the price of fuel for final consumers, if only lowering the price for transporters or, if necessary, applying other types of alternative measures such as lowering the price of public transport. As was already done in 2022. Help with the purchase. The most obvious measure that the State can apply if necessary is a purchase subsidy. In fact, gas stations, aware that this could make them advance the money as happened four years ago, They have been warning the Government that they would be against. However, its activation in 2022 left some doubts: Aid to public transport. In parallel with aid for the purchase of fuel, the Government tried to promote the use of public transport with very substantial price reductions. The use of this means of transportation skyrocketed. Renfe even spoke of an increase in travelers of between 25 and 40% and 1.5 million requests for new free passes. Measures that, due to their application, also had their shadows: And measures that have been extended over time. One of the problems that the Government has is that aid for public transport has been extended over the years. More or less reluctantly, some autonomous communities have maintained the reductions in the price of season tickets. Aid that was also extended to bus services. By 2026, the Government announced a single pass for all of Spain. For 60 euros (30 if you are under 26 years old) you can use the entire medium-distance network, Cercanías, Rodalies and buses (in which the State provides the service). That is to say, there is little room to propose something much cheaper without putting the viability of the service at risk. Taxes? It is another possibility but it seems very complicated for this to be applied. On a liter of gasoline, there are two types of taxes that the Government can reduce to lower the price of a liter of fuel: the Special Tax on Hydrocarbons and VAT. Right now, each liter of fuel is taxed by a general and regional section (which is linear) in the Special Tax on Hydrocarbons, remaining as follows: Unleaded gasoline 98: 0.504 euros/liter. Unleaded gasoline 95: 0.473 euros/liter Diesel: 0.379 euros/liter. To the price, after applying the tax and the cost at which the company wants to sell, 21% VAT is applied. The problem is that these types of measures are considered ineffective for public coffers (lower collection) and The European Union has been demanding from Spain for some time that raises the price of diesel. A measure that would involve eliminating the current bonus that this fuel has in the tax outlined above and that has been repeatedly ignored from our country.

Iran has spent decades excavating its “missile cities.” Satellite images have just revealed that they are a death trap

For years, Iran has shown the world tunnel videos endless tunnels dug under mountains, with military trucks circulating between missiles lined up as if they were cars in an underground subway. It was understood that many of these facilities extend kilometers underground and are part of one of the military fortification programs. most ambitious in the Middle East. What almost no one knew until now is to what extent this gigantic hidden labyrinth could become a key piece of the current conflict. The cities, but with missiles. Yes, for decades, Iran has excavated an extensive underground base network known as “missile cities”, complexes hidden under mountains and hills intended to protect its enormous ballistic arsenal against air attacks and guarantee the regime’s retaliation capacity even in the event of open war. There are numerous videos Officials released in recent years where we could see long tunnels illuminated by artificial lights, windowless corridors and convoys of trucks loaded with missiles ready to move to the surface, an entire military architecture designed to hide thousands of short and medium range projectiles away from spy satellites and enemy bombers. Some installations even incorporate silos dug into the rock or mechanical systems on rails to move missiles within underground galleries, a perfectly assembled choreography reflecting a strategic project conceived to ensure arsenal survival Iranian in a protracted conflict. The images that reveal the paradox. However, the war has begun to show the unexpected reverse of that strategy. Recent images from space have revealed Smoldering remains of destroyed launchers and missiles near the entrances to several underground complexes, a sign that systems hidden underground are becoming extremely vulnerable at the moment when they must go outside to shoot. It makes sense. American and Israeli surveillance planes, armed drones and fighters They patrol constantly over the areas where these facilities are located, observing the entrances to the tunnels and attacking the launchers as soon as they appear on nearby roads or canyons. In other words, what for years was a system designed to hide mobile weapons It thus becomes a relatively predictable pattern: tunnel entrances, exit roads and deployment areas that can be monitored from the air and destroyed as soon as activity is detected. From strategic refuge to death trap. They remembered in the wall street journal A few hours ago this change has revealed a structural problem in the very concept of missile cities. Underground complexes are very difficult to destroy from the air, but they are also fixed installations whose location is known by Western intelligence services. In practice, this means that much of the arsenal remains stored in specific places while enemy planes continually fly over the airspace, waiting for the moment when the launchers come out to act. Many military analysts summarize the dilemma in a simple way: What was previously a mobile and difficult to locate system is now concentrated in fixed points, which facilitates its surveillance and reduces its capacity for surprise. Commercial satellite images themselves show destroyed launchers As soon as they left the mouths of the tunnels, fires were caused by leaked fuel and access to facilities bombed with heavy ammunition. Missile base north of Tabriz in Iran. The image on the left belongs to February 23, the one on the right from March 1 after the first attacks The air offensive against underground infrastructure. As the first week of war approaches, the military campaign has begun to focus increasingly on these infrastructures. They told Reuters that the first phase of the attacks focused on destroying visible launchers and surface systems capable of firing at Israel or US bases in the region, while the second stage aims straight to the bunkers and buried warehouses where missiles and equipment are stored. Israeli aviation, with American support, has attacked hundreds of positions and has managed to drastically reduce the number of launches, while an almost constant air offensive that hits targets continues. both in Iran and Lebanon during the same missions. The stated objective is to progressively degrade Iran’s ability to launch ballistic missiles and drones until it is completely neutralized. Missile base north of Kermanshah in Iran. The image on the left belongs to February 28, on the right it belongs to March 3 A gigantic arsenal underground. The actual scope of these facilities remains difficult to determine. There are military estimates that place the Iranian arsenal before the war between about 2,500 and up to 6,000 missilesstored in different facilities throughout the country, many of them excavated under mountains or in remote areas of the territory. Despite the attacks, Iran has managed to launch more than 500 missiles against Israel, US bases and targets in the Gulf since the start of the conflict, although many have been intercepted and the pace of salvos has decreased rapidly. That drop suggests that attacks on launchers and storage centers are beginning to erode the country’s ability to respond. The strategic dilemma. The result is a strategic paradox that is just beginning to become visible. Missile cities were designed to protect the core of Iranian military power and ensure its ability to retaliate, but in a scenario where the enemy dominate the air and watch constantly the entrances to these complexes can become choke points for the arsenal itself. Iran has spent decades excavating these underground bases with the intention of making its missiles invisible. But satellite images of the war are showing something very different: that this labyrinth of tunnels, designed as a shelter, can become one of its greatest vulnerabilities when the launchers are forced to surface under the look constant flow of planes, drones and satellites.

We believed that GLP-1 drugs were only going to change obesity. They just turned upside down how we treat addictions

The famous GLP-1 receptor agonistsamong which some protagonists such as Ozempic stand out, have revolutionized the treatment of type 2 diabetes and of obesity. However, for some time patients and doctors had been reporting a “side effect” that was as surprising as it was hopeful, since it was seen that this treatment made people not feel like drinking alcohol or smoking. New routes. What began as a trickle of anecdotes in doctors’ offices has ended up being the target of study by different research teams who have seen here a new way of understanding the mechanism of addictions in humans. Now, a recent study published in B.M.J. backed by new clinical trialssuggests that these medications could be the key to treating addictive substance use disorders. How it looked. The heavyweight of this new research is a gigantic cohort study published in 2026, where the data of 606,434 United States veterans with type 2 diabetes. Here it was divided into two groups: those who started treatment with GLP-1 drugs such as Ozempic and those who took SGLT2 inhibitorswhich is one of the accepted treatments for advanced type 2 diabetes. The results. But the most shocking data came when analyzing patients who already had a previous history of addictions. In this group, the use of Ozempic resulted in a dramatic decrease in addiction problems requiring urgent treatment, but also saw a lower rate of hospital admissions, lower drug-related mortality, a drop in overdoses, and even a significant reduction in suicidal ideation and attempts. The essays. Although observational studies are very valuable, they also you have to go to the laboratory to see what is happening. Here, a 2025 randomized trial demonstrated that taking Ozempic dramatically reduced alcohol self-administration in a laboratory setting. Here patients reported less anxiety about having to have a drink or a cigarette, fewer days of heavy consumption, and incidentally, a decrease in the number of cigarettes they smoked per day. In the past, a study published in 2022 showed that using exenatide it was not possible to generally reduce the days of consumption of these drugs, but it was possible to see how the drug had a direct effect on some specific parts of the brain that are related to the reward centers. Because? That a drug designed for the pancreas affects our relationship with alcohol and tobacco, the truth is that it can raise many questions. The answer lies in the brain, since some reviews suggest that GLP-1 receptors not only regulate blood sugar or slow down gastric emptying. These receptors are also found in key brain areas that control the dopamine pathway, which is why, by activating them, drugs such as emaglutide or liraglutide attenuate the sensation of reward. In rodents, for example, they block the reinforcement produced by substances such as cocaine, opioids or nicotine and, basically, the drug stops “feeling good.” A paradigm shift. As can be seen every day, constant drug use over time can have devastating consequences for the lives of people and those around them. The problem is that right now there are few approved pharmacological therapies to support these addicts, and this makes any clue to have a new therapeutic door welcome. Although more research and large-scale Phase III trials are needed for regulatory agencies to officially approve their psychiatric use, GLP-1 drugs appear to be doing something that medicine has been seeking for decades: “satiating” not only physical hunger, but also the brain’s chemical hunger.

iPhones were supposed to be the most secure cell phones in the world. It was supposed

Imagine a tool capable of bend the security of a mobile simply browsing a website, without downloading any file or accepting any permission. It’s scary, but if that cell phone is also an iPhonethings get even worse. It is not the argument of a conspiracy theory, it is reality and it has just destroyed Apple’s aura of invulnerability. What has happened? Google security engineers have published a report detailing ‘Coruna’, a sophisticated hacking kit designed specifically to compromise iOS devices. According to the investigation, Coruna uses a chain of ‘zero-day’ vulnerabilities which give almost total access to the device. It’s going to be something similar to Pegasusbut even more sophisticated. The most disturbing thing is that it has been located in the hands of cybercriminals, but its origin appears to be in US government agencies. What Coruna does. As we said, all you have to do is visit a malicious website for it to take action. Coruna’s architecture is based on an extremely complex exploit chain that takes advantage of flaws in the browser’s rendering engine and in the operating system core itself. In this way, it takes control of the iPhone silently, without the user downloading any files or accepting any additional permissions. The good news is that Apple patched one of these vulnerabilities with iOS 17.3, so if your phone is on this version or higher, you have nothing to worry about. However, despite these limitations, it is estimated to have infected tens of thousands of devices. Image: Google Timeline. In early 2025, Google first detected parts of this exploit chain that had been used by a commercial surveillance company. In the middle of the year he reappeared in a campaign against Ukraine attributed to Russian espionage and at the end of the year he made the jump to China, where he was hiding on fake websites about finance and cryptocurrencies. The kit stole cryptocurrencies and other data from victims, such as photos or email accounts. Who has developed this. In statements to Wiredthe head of the security company iVerify, highlights that the code is “extremely sophisticated and its development has cost millions of dollars.” The most striking detail is that Coruna shares modules with the one known as “triangulation operation”another cyberattack targeting iOS discovered by Kaspersky and attributed to the NSA. At the moment it is a suspicion, but according to iVerify, the signs clearly point to it being the work of some US government agency or contractor. How it has ended up in the wrong hands. It is the question that experts ask themselves and at the moment there is no answer, but there is a hypothesis. Zero-day exploits are those that the manufacturer, in this case Apple, has not yet detected and are the most expensive ones sold on the black market. The theory is that it was sold by an exploit broker to some foreign intelligence service and from there it made the jump to cybercrime organizations. iVerify analyzed a version of Coruna and found that the code had been modified to install malware that emptied cryptocurrency wallets. These additions were “poorly written” and contrasted greatly with the underlying code, which fits with the theory that it was conceived by a very well-funded organization and then ended up in the world of cybercrime.

OpenAI is now the bad guy of AI. GPT-5.4 will have to be very good to change that

He soap opera that has been assembled with the Department of Defense has made the perception clear in recent days for two of the leading companies in AI. Suddenly Anthropic She is the good one in the movie and OpenAI is the bad guy. And whether precisely for that reason or not, Sam Altman’s team has decided that now was the time to launch a new and promising AI model: GPT-5.4. Hello GPT-5.4. In it OpenAI official announcement explain how this new model will currently be available in two variants: GPT-5.4 Thinking and, for those who want “maximum performance in complex tasks”, GPT-5.4 Pro. We are looking at a foundational model that is better than ever in its reasoning, programming capacity and above all in one very fashionable thing: “agent flows”. Or what is the same: do things for us. The “Use My Computer” mode, protagonist. It is a free translation, but it is more or less what OpenAI highlights with what is probably the great novelty of this model. As they say in the announcement, this is their first model “with native computer use capabilities.” It is capable of taking control of our machine and doing things for us autonomously, completing complex cycles of action and solving problems that arise. Not only that: according to its creators GPT-5.4 “is our most token-efficient reasoning model, using significantly fewer tokens to solve problems than GPT-5.2.” Or what is the same: AI doing things for us will be cheaper and it will solve them even better. Use the computer better than us. The benchmarks certainly seem to point to fantastic performance in these tasks. In the OSWorld-Verified test, which measures a model’s ability to navigate a desktop environment using screenshots and virtual mouse and keyboard actions, GPT-5.4 achieves a 75% success rate. That is not only better than the 47.3% of GPT-5-2: it even exceeds human performance, which is 72.4% according to the creators of this benchmark. Other tests of this type that evaluate the ability of an AI model to navigate also make it clear that GPT-5.4 is clearly ahead of its predecessors. The ARC-AGI thing is scary. Machines were supposed to have a lot of trouble solving abstract reasoning problems that humans are naturally fantastic at, but oh well. In recent times we have seen how the ARC-AGI 2 test, which seemed like a challenge for AI models, has become increasingly acceptable for said models. GPT-5.4 gives a new bite to that reality, and in its Pro version it already manages to solve 83.3% of the tasks (73.3% in the standard model) when in GPT-2 the rate was 52.9%. It is a simply brutal jump, and although in other tasks that jump is not so notable (it programs somewhat better according to SWE-Bench Pro, but not much), it is clear that we are facing an extraordinary model. Perfect for OpenClaw? That ability seems to come to him that was not even painted OpenClawthe AI ​​agent that has become a phenomenon in this area in recent weeks. OpenAI ended up signing its creator and is in some way the “owner” of the projectand this performance in agentic tasks is expected to be very useful for everything OpenClaw does, which is basically that: manage your machine for you. That’s where GPT-5.4 can really come into its own. And you can trust him more. According to those responsible for OpenAI, GPT-5.4 is now better at answering questions that require seeking information from multiple sources, and “identifying the most relevant ones, particularly for “needle in a haystack” type questions, and synthesizing them into a clear and well-reasoned answer.” What’s more: they rate it as the model most focused on answering based on facts and say that it is 33% less likely to answer something that is false compared to GPT-5.2. But be careful: it is very, very expensive. These capabilities, however, will not come cheap. With this launch OpenAI has updated its prices, and it has done so by making it clear that if you want the best, you will have to pay for it. The “standard” GPT-5.4 model costs $2.50 per million input tokens and $15 for output tokens, while the Pro costs a whopping $30 and $180 respectively. Claude Opus 4.6, which was until now considered the best AI model, costs $10 per million input tokens and $25 per million output tokens: it was already expensive, but GPT-5.4 Pro leaves it almost as a “bargain” AI model. Trying to stop the bleeding. The model appears at a delicate moment. According to various sources, ChatGPT has lost 1.5 million users since announcing that they had reached an agreement with the Department of Defense. That decision provoked much criticism, a movement on networks that spoke of “cancel ChatGPT” and internal tensions. Before the scandal there was already talk of the potential appearance of GPT-5.4, but it is clear that the launch now takes on a double meaning. It doesn’t just have to be better than everyone else: it has to redeem OpenAI. And above all he needs a victory. Public perception seems clear: OpenAI has been suffering lately, whether from internal dramas, talent drains, or temporarily falling behind in the performance of its models. GPT-5.4 is not a simple evolution of its founding model, because what OpenAI needs is for this model to succeed and convince people to “love again” (figuratively, you know what we mean) ChatGPT. We’ll see if he succeeds. In Xataka | Sam Altman says he’s terrified of a world where AI companies believe themselves to be more powerful than the government. It’s just what you’re building

ended up sneaking in errors and references that didn’t add up

Artificial intelligence has become an everyday tool for millions of people. Today many use it to write emails, summarize documents or translate texts in a matter of seconds. However, this speed has a less visible side: generative systems can also make mistakes, invent data or alter sources without the user immediately noticing. When these errors appear in one of the largest encyclopedias in the world, the situation changes completely. That is precisely what has happened on Wikipedia with a series of translations carried out with the help of AI. The opening episode. It all started within the Wikipedia community itself. Some editors began reviewing recent translations and noticed something strange: certain texts included phrases that did not appear in the cited sources or references that did not seem to fit with what the article stated. According to 404 Mediathese translations were part of a project promoted by an organization that sought to expand the presence of Wikipedia content in different languages ​​using language models to speed up the process. When translation invents. As editors began to examine these translations in more detail, the problems became more evident. One of the cases cited by 404 Media is that of a draft article about the French royal family La Bourdonnaye. The translated text included a reference to a book and a specific page to explain the origin of the family. However, when editor Ilyas Lebleu, known on Wikipedia as Chaotic Enby, reviewed that source, he discovered that the page cited was incorrect. Lebleu added that, when doing a quick review of several translations, he also found interchanged references, phrases without a source, and cases in which paragraphs were added based on material unrelated to what was being written. It was published or remained in draft. The case also raised a relevant question: whether these errors had appeared in already published articles or whether they were detected during the review process. At least one of the problematic examples was identified in a draft translation, allowing editors to revise it before it was finalized. With the material provided here, however, it cannot be stated how many translations with problems were published and how many remained under review. Who is behind these translations. Here appears the name of Open Knowledge Association (OKA), a non-profit organization that claims to work to improve Wikipedia and other open platforms. As the organization itself explains on its website, its model consists of offering monthly stipends to collaborators and translators who work full-time expanding the encyclopedia’s content, and “taking advantage of AI (large language models) to automate most of the work.” According to 404 Media, editors who investigated the project concluded that it relied on contractors. The editors’ response. As more problematic examples appeared, the Wikipedia community decided to intervene. The editors reviewed the operation of the translation project and ended up establishing new restrictions for those who participated in it. OKA-linked translators who accumulate four strikes for unverifiable content within a six-month period may be blocked without additional notice if a new case appears. Additionally, content added by a translator that ends up being blocked may be removed preventively, unless another reputable editor takes responsibility for reviewing it. OKA explains. The organization mentioned in the debate also offered its version of the events. Jonathan Zimmermann, founder and president of the Open Knowledge Association, explained to the aforementioned media that the project’s translators work on an hourly basis and that there is no fixed goal of articles per week. In addition, he admitted that “errors happen,” although he defended that the system includes human verification and review of sources. Following the discussion on Wikipedia, he added, the organization is introducing a second review with another AI model to detect possible errors before publishing, and is studying the possibility of adding peer review mechanisms if necessary.

There are asteroids that go almost unnoticed and others that force us to look at them much more carefully. 2024 YR4 belongs to that second group. When it was discovered at the end of 2024, the first calculations of its trajectory still had enough margin of error to contemplate a very small possibility of impact with Earth. That scenario was soon ruled out, but, as ESA explainsthe case remained under follow-up for a different reason: a doubt was left open about the Moon which was not resolved until new observations arrived. Impact risk. With data available since spring 2025, trajectory models indicated that the asteroid had about a 4% chance of hitting the Moon on December 22, 2032, an estimate that NASA placed at 4.3% in its previous calculations. It was not a high percentage, but it was significant enough for the teams dedicated to monitoring near-Earth objects to follow it with special attention. Furthermore, we are talking about an object of about 60 meters. How Webb came into play. To clear up that doubt, something more than the usual telescopes was needed. An international team of astronomers identified two very specific windows in February 2026 in which the James Webb Space Telescope could try to detect the asteroid, which at that time was just an extremely faint point millions of kilometers away. It involved using one of the most complex scientific instruments built to date to locate an almost invisible object and measure its position with the necessary precision to project its orbit almost seven years into the future. Key piece. The observations were made on February 18 and 26, 2026 with the camera NIRCam of the James Webb telescope. From these images, astronomers compared the position of the asteroid with that of the background stars, whose coordinates are known with great precision thanks to ESA’s Gaia mission. ESA adds a relevant detail to understand why this went ahead: the planning and analysis was coordinated with ESA’s Near-Earth Object Coordination Center, NASA’s Center for Near-Earth Object Studies and the Webb mission team. With this new data package, the orbital models were adjusted enough to close the mystery. James Webb analyzed the position of the asteroid in relation to the background stars The flyby distance. With the new calculations, monitoring teams can now estimate quite accurately what the asteroid’s passage through the lunar environment will be like. According to NASA, it will pass on December 22, 2032 about 21,000 kilometers from the surface of the Moon. That range is enough to eliminate the impact scenario that had been on the table for months. In other words, the object will continue on its way through the solar system without hitting either the Moon or Earth. Surveillance doesn’t stop. Programs such as ESA’s Space Security or NASA’s tracking systems continue to detect and analyze near-Earth objects to anticipate any possible future threats. The logic is simple: the sooner a potentially dangerous object is identified, the more room there will be to study its trajectory and assess the real risk. In this case, the result has been reassuring, but it also illustrates, as ESA insists, what planetary defense means in practice when a doubt is resolved with more data and better measurements.
