With the April 15 tax filing deadline in the rearview mirror, you’re likely to turn your attention to other things. But before you do, it’s in your best interest to tie up a few tax-related loose ends. IRS statute of limitations Generally, the IRS’s statute of limitations for auditing a tax return is three years from the return’s due date or the filing date, whichever is later. However, some tax issues are still subject to scrutiny after three years. For example, if the IRS suspects that income has been understated by 25% or more, the statute of limitations for an audit extends to six years. If no return was filed or fraud is suspected, there’s no limit on when the IRS can launch an inquiry. It’s a good idea to keep copies of your tax returns indefinitely as proof of filing. Supporting records generally should be kept until the three-year statute of limitations expires. These documents may also be helpful if you need to amend a return. So, which records can you throw away now? Based on the three-year rule, in late April 2026, you’ll generally be able to discard most records associated with your 2022 return if you filed it by the April 2023 due date. Extended 2022 returns could still be vulnerable to audit until October 2026. But if you want extra protection, keep supporting records for six years. What records should you retain? Documentation supporting your income, deductions and credits that you generally should retain following the three-year rule may include: Various series 1099 forms, such as Form 1099-NEC, “Nonemployee Compensation,” Form 1099-MISC, “Miscellaneous Income,” and Form 1099-G, “Certain Government Payments,” Form 1098, “Mortgage Interest Statement,” Property tax payment documentation, Charitable donation substantiation, Records related to contributions to and withdrawals from Section 529 plans and Health Savings Accounts, and Records related to deductible retirement plan contributions. You’ll also want to hang on to some tax-related records beyond the statute of limitations. For example: Retain Forms W-2, “Wage and Tax Statement,” until you begin receiving Social Security benefits. That may seem long, but if questions arise regarding your work record or earnings for a particular year, you’ll need your W-2 forms as part of the required documentation. Keep records related to investments and real estate for as long as you own the assets, plus at least three years after you sell them and report the sales on your tax return (or six years if you want extra protection). Hang on to records associated with retirement accounts until you’ve depleted the accounts and reported the last withdrawal on your tax return, plus three (or six) years. Retain records that support figures affecting multiple years, such as carryovers of charitable deductions or casualty losses, until they have no effect, plus seven years. Keep records that support deductions for bad debts or worthless securities that could result in refunds for seven years because you have up to seven years to claim them. Other tax-related chores As you can see, keeping tax-related records is critical. So put yourself in a good position for filing your 2026 return next year by carefully tracking expenses potentially eligible for deductions or credits on an ongoing basis. For example, if you’re self-employed and use your personal vehicle for business purposes, maintain a mileage log recording the date, mileage, purpose and destination of each trip. Or if you regularly donate to charity, keep the receipts or written acknowledgments you receive. (Additional substantiation may be required depending on the size and type of donation.) In addition, this is a good time to reassess your current tax withholding to determine if you need to update your Form W-4, “Employee’s Withholding Certificate.” You may want to increase withholding if you owed taxes this year. Conversely, you might want to reduce it if you received a hefty refund. Changes also might be in order if you experience certain major life events, such as marriage, divorce, birth of a child or adoption, this year. If you make estimated tax payments throughout the year, consider reevaluating the amounts you pay. You might want to increase or reduce the payments due to changes in self-employment income, investment income, Social Security benefits and other types of nonwage income. To preempt the risk of a penalty for underpayment of tax, consider paying at least 100% of the tax shown on your 2025 tax return (110% if your 2025 adjusted gross income was over $150,000 — or over $75,000 if you’re married and filed separately) through withholding and/or four equal estimated tax payments. What’s this? A letter from the IRS? After filing your tax return, you may receive a letter in the mail from the IRS. While such letters can be alarming, don’t assume the worst. The letter might simply inform you of a refund adjustment (up or down) based on a math or similar error on your return. If you agree with the change, generally no response is needed. If you disagree, contact the IRS by the date indicated. Or the letter might propose a change to your return based on information reported by third parties, such as employers or financial institutions. In this case, follow the instructions to respond, include any required documentation, and note whether you agree or disagree with the proposed change. Of course, an IRS letter could inform you that your return is being audited. It’s important to remember that being selected for an audit doesn’t always mean there’s a significant error on your return. For example, your return could have been flagged based on a statistical formula that compares similar returns for deviations from “norms.” Further, if selected, you’re most likely going to undergo a correspondence audit. These account for a majority of IRS audits. They’re conducted by mail for a single tax year and involve only a few issues that the IRS anticipates it can resolve by reviewing relevant documents. According to the IRS, most audits involve returns filed within the last two years. If you receive notification of a correspondence audit, you and your tax advisor should closely follow the instructions. You can request additional time if you can’t submit all the documentation requested by the specified deadline. Don’t ignore the letter. Failure to respond can lead to the IRS disallowing some tax breaks you claimed and issuing a Notice of Deficiency (that is, a notice that a tax balance is due). Be proactive Organizing your past and current-year tax records now can facilitate a smoother tax filing next year or a less painful audit of a recent return. Similarly, adjusting your withholding or estimated tax payments can mean more money in your pocket now or no (or smaller) underpayment penalties next April.
