Tax season 2026 will be the first time most households feel the full force of the new rules that will shape their 2025 returns, and the stakes are high. A sweeping law branded the One Big Beautiful Bill has rewritten deductions, credits, and even how refunds are delivered, while the Internal Revenue Service is adjusting to budget cuts and new technology. Whether you try to navigate this alone or pay for help could easily be the difference between a bigger refund and an expensive mistake.
I want to walk through what has changed, how complicated the average return is about to become, and a practical way to decide if you can still go the do‑it‑yourself route or if this is the year to bring in a professional.
New rules that will reshape your 2025 return
The defining feature of the coming filing season is a dense package of changes often referred to as OBBB Changes, which policy analysts say will dominate how people file in early 2026. The analysis of OBBB Changes notes that even though Presiden Trump and Congress kept the familiar seven‑bracket structure, the underlying rules around deductions and credits are shifting in ways that will surprise many filers. A companion brief on the same package of Changes underscores that the law will touch everything from withholding to the forms people use.
On the ground, that means your 2025 return will be built on a new mix of incentives. The “One Big Beautiful Bill” created fresh write‑offs for tip income, overtime pay, car loan interest and other everyday costs, according to the Key Takeaways laid out for filers. A separate breakdown of those same One Big Beautiful provisions stresses that these are layered on top of existing credits, not simple replacements. For anyone who juggles multiple jobs, earns tips, or finances a car, the opportunity is real, but so is the risk of missing a new line or mis‑documenting income.
Standard deduction, SALT and brackets: why the math is trickier
One of the headline shifts is the size of the standard deduction and who benefits from itemizing. The Internal Revenue Service has spelled out that for Tax year 2026 the basic amounts will be $32,200 for married couples filing jointly and $16,100 for single filers and married individuals filing separately, figures that appear in the official Tax guidance. A separate IRS summary of the same One, Big, Beautiful provisions confirms those thresholds and makes clear they interact with the new deductions rather than sitting apart from them.
At the same time, the law reshapes the state and local tax break that has been a flashpoint for homeowners. A reform summary notes that the policy now Raises SALT cap to $40,000 if you earn up to $500,000, a change that appears in the official Summary of the law and is repeated in a second explanation that highlights how the rule Raises SALT for eligible homeowners. Meanwhile, the seven federal tax brackets, including the 32% and 35% bands, are now permanent, according to a planning guide that lists the full set of rates at 10%, 12%, 22%, 24%, 32%, 35%, and 37% in its overview of Tax brackets. A second version of that same explanation of 32%, 35% underscores that the standard deduction has climbed alongside those permanent brackets, which makes the decision to itemize more nuanced than it was a few years ago.
Refunds, IRS cuts and the end of paper checks
Even if your tax math looks better on paper, the experience of getting money back is changing. Analysts expect Refunds for the 2026 filing season are expected to be larger than in prior years, a point made explicitly in a breakdown of why Refunds for the upcoming season may jump. A separate analysis framed around Why those refunds are rising links the trend to the 2025 law and its richer deductions, reinforcing that the new rules can be generous if you claim everything correctly, as described in the same Why discussion.
At the same time, the machinery that delivers those refunds is under strain. Budget reductions have left the IRS smaller, and experts warn that When taxpayers could receive refunds is now an open question, with Another concern being how quickly the agency can process returns in this environment, according to a detailed look at how cuts may affect When refunds arrive. On top of that, WASHINGTON officials have announced that The Internal Revenue Service, working with the Department of the Treasury, will phase out paper refund checks for individual taxpayers, a shift spelled out in the agency’s notice on WASHINGTON. A second version of that same announcement on how Internal Revenue Service will end paper checks by the end of 2025 means anyone who still relies on a physical check will need to set up direct deposit or a debit card alternative well before filing.
DIY software is stronger, but so are the traps
On the surface, the case for doing your own taxes has never looked better. Pros of DIY Tax Filing include the fact that Cost is low and software is Effective at walking people through standard situations, with One of the main selling points being that you can file from your couch on your own schedule, as outlined in a guide to Pros of DIY. A second discussion of those same pros emphasizes that if your return is simple, the Cost savings and Effective step‑by‑step prompts can be compelling, a point repeated in the overview of One of the key advantages.
Yet the new law has multiplied the places where a do‑it‑yourself filer can go wrong. The “One Big Beautiful Bill” section of the Key Takeaways warns that the fresh deductions for tip income, overtime and car loan interest come with eligibility rules and documentation requirements that are easy to overlook, a caution that appears in the detailed Key Takeaways for filers. A broader explainer titled Taxes 2025‑2026: One Big Beautiful Bill Act Tax Law Changes and How That Impacts You notes that On July 4, 2025, the legislation known as the One Big Beautiful Bill Act Tax Law Changes and How That Impacts You took effect, and that the learning curve for ordinary households will be steep, as laid out in the overview of Taxes. A second version of that same explanation of One Big Beautiful underscores that the law touches multiple schedules and forms, which magnifies the risk that a casual filer will miss a new checkbox or misclassify income.
When paying a pro can actually save you money
Professional help is not cheap, but the economics look different once you factor in the complexity of the new rules. One analysis of Value in tax preparation notes that Professional help costs more upfront, often around $200 to $300 for simple returns, but that those preparers frequently spot deductions and credits that software users skip, as described in the comparison of Value. A separate guide to Pros of DIY acknowledges that Cost is a major factor, but also stresses that One of the trade‑offs is the risk of missing nuanced breaks, a point made in the overview of Pros of DIY. That same discussion of Cost and how One of the key questions is your budget makes clear that hiring help is a financial decision as much as a tax one.
