A lower-than-expected 2025 tax refund is likely due to reduced withholding, fewer pandemic-era tax credits, increased income, or life changes like a dependent turning 17. Inflation adjustments to tax brackets and potential tax offsets for unpaid debt can also result in a smaller refund or a balance due.
Even though the IRS didn't update federal withholding tables this year after the Working Families Tax Cut Act passed, your refund could still be smaller if: You updated your Form W-4 after a raise, new job, or other big life change. Your employer withheld taxes more accurately than in prior years.
Many new tax laws for 2025 were part of the One Big Beautiful Bill Act, which included significant changes, including expanded tax brackets, deductions, and new credits, to help taxpayers maximize refunds. Form 1099-DA for crypto transactions and Form 1098-VLI for car loan interest are new for the 2025 tax year.
Marginal tax rate brackets changed
Whether your income went north or south—or even stayed the same—the rate at which your income is taxed could have changed when income ranges for the 7 federal tax brackets were adjusted for tax year 2025. Across the board, the brackets increased by 2.8% from 2024 because of inflation.
You suddenly owe taxes because your payments during the year (withholding or estimated) didn't cover your actual tax liability, often due to life changes like a raise, new job, side hustle, or selling investments, which increased your income or reduced deductions, or because tax laws/credits changed, leaving you with a surprise bill. Common culprits are under-withholding from your paycheck, earning taxable gig income, or missing quarterly payments.
Each year, the IRS adjusts more than 60 tax provisions to keep income tax brackets, deductions and other inputs in line with the cost of living. For the 2025 tax year (filing returns in 2026) these adjustments, including federal income tax brackets, increased on average by about 2.8%.
If you didn't account for each job across your W-4s, you may not have withheld enough, so your tax refund could be less than expected in 2026. Or, if you had a salary increase in 2025 but didn't update your tax withholding accordingly, you could receive a smaller refund.
To avoid the 22% tax bracket (or any higher bracket), focus on reducing your taxable income through strategies like maxing out 401(k)s and HSAs, deferring bonuses, tax-loss harvesting, smart charitable giving, and strategic asset location, understanding that higher rates only apply to income within that bracket, not your entire income.
Some of the major tax changes effective from April 1, 2025, are revised tax slabs, rebate of up to Rs. 60,000, revised ITRU deadlines, calculation of partner's remuneration allowable as a deduction and revised TDS/TCS threshold limits. What is the Rebate available under section 87A?
No, the IRS is not issuing new $1400 stimulus checks; the final pandemic-era payments for the Recovery Rebate Credit (the third stimulus) were sent out by early 2025 to eligible people who missed them by filing their 2021 return by the April 2025 deadline. While payments were made in late 2024 and early 2025, that was the final opportunity, and any current claims of new stimulus checks are likely scams or misinformation, as Congress has not approved any new federal stimulus programs.
Some of the most common reasons are because you earned more income this year, you did not withhold enough taxes from your pay or you did not make enough estimated tax payments, or your deductions and credits were reduced this year.
At a glance. If your total income is between £100,000 and £125,140, the tapering of the personal allowance means you could end up paying an effective 60% income tax rate. Almost 725,000 workers will fall into the 60% tax trap in 2025-26, according to HMRC, up from about 300,000 in 2017-2018.
Tax Foundation estimates the OBBBA reduced individual taxes by $129 billion for 2025, and outside estimates suggest up to $100 billion of that could be received as higher refunds this filing season, pushing average refunds up by up to $1,000.
Entering information inaccurately. Wages, dividends, bank interest, and other income received and that was reported on an information return should be entered carefully.
Lawmakers have passed legislation called the “One Big Beautiful Bill Act” to make the expiring tax cuts permanent, provide additional tax cuts and changes to the tax code, and reduce spending. President Trump signed the bill into law on July 4, 2025.
Inflation adjustments to deductions and brackets
For example, the top end of the 10% tax bracket for a single filer will increase from $11,600 for 2024 to $11,925 for 2025. The 37% rate starts at $609,350 for a single filer in 2024 but doesn't start until $626,350 for 2025.
