7 Tax Mistakes Many Retirees Make That Could Trigger an Audit

Retiring quietly doesn't always mean retiring stress-free, especially when it comes to taxes. Many seniors assume their IRS risk drops once they stop working, but new algorithm updates and financial changes in retirement can create unexpected audit triggers. Small errors, overlooked reporting rules, or mismatched information can suddenly draw scrutiny. Understanding these risks can help you avoid money mistakes as you navigate life after work.

Here are the key reasons retirees are seeing more IRS attention and how to protect yourself.

Social Security tax errors can raise questions

Many retirees are surprised to learn that Social Security benefits can be taxable, depending on total income. If a retiree miscalculates how much of their benefit should be reported — or fails to include it entirely — the IRS system may flag the discrepancy. This error might also happen when combining Social Security benefits with a small pension or income from part-time work.

Benefit statements are updated annually, and mismatches between what the SSA reports and what appears on your return can trigger automated alerts. Keeping records organized and reviewing SSA Form SSA-1099 carefully each year helps prevent misreporting issues that may lead to inquiries.

IRS algorithms can flag 'unusual' patterns

The IRS increasingly relies on advanced algorithms to detect filing patterns that differ from past years. For retirees, suddenly shifting from a full-time income to no wage income can appear unusual unless other data points line up properly.

Large withdrawals, irregular investment activity, or new deductions may also raise attention, as might changing your tax preparer. While these actions aren't inherently problematic, accurate documentation and consistent reporting can help ensure your return doesn't get flagged unnecessarily.

Complications with inherited property or home sales

Selling a long-owned home or inheriting property can significantly complicate your tax return. Errors in calculating capital gains, missing cost-basis documentation, or applying exemptions incorrectly might alert the IRS.

Retirees might assume these transactions are tax-free and straightforward, but property rules are nuanced, especially when using the step-up basis after inheriting a home. Keeping detailed records and consulting a tax professional can help ensure your return reflects accurate numbers and may help avoid costly scrutiny later.

Required minimum distribution (RMD) confusion

Generally, once retirees reach age 73, they must begin taking required minimum distributions from traditional IRA and 401(k) retirement accounts. Missing an RMD, taking the wrong amount, or reporting it inaccurately can cause IRS flags because these withdrawals must be tracked precisely.

Seniors who juggle multiple accounts, such as IRAs, 401(k)s, or inherited accounts, could be especially prone to errors. Reviewing IRS guidelines annually and coordinating distributions can help ensure compliance and may reduce audit risk.

Moving out of state and collecting state pensions

Retirees who relocate may face unexpected tax complications when collecting pensions or other state-specific benefits. Some states may tax pensions differently, and others may require you to update withholding or file additional forms when you move.

If the IRS receives conflicting information between state tax systems, financial institutions, and the information included on your federal tax return, it may prompt an inquiry. Keeping your information updated with both state and federal agencies may help prevent these mismatches.

Claiming charitable deductions without proof

Seniors may give generously, but failing to document charitable contributions properly can cause issues. The IRS requires detailed receipts for donations.

If a retiree claims a large deduction but cannot produce verification, algorithms may flag the return for review. Keeping organized records and ensuring all contributions meet IRS rules can help deductions hold up under scrutiny.

Claiming caregiver and dependent credits may draw more attention

Many retirees care for grandchildren, adult children with disabilities, or aging relatives. Claiming certain caregiver credits, dependent deductions, or head-of-household status can raise IRS questions if documentation isn't clear.

Credits related to caregiving are legitimate, but they may require specific proof of support and residency. Ensuring eligibility before claiming these benefits can help avoid accidental red flags.

How to respond if you're chosen for an IRS audit

Getting an audit notice is stressful, but responding quickly and calmly makes the process easier. Gather all requested documents, such as receipts, SSA forms, pension statements, or brokerage reports, before replying.

It may be wise to get help from a tax professional who specializes in audit support. Staying organized and maintaining open communication with the IRS can help resolve issues smoothly.

Bottom line

IRS audits can feel especially unsettling for retirees who thought their tax life would get simpler, not more complicated. Yet changes in income sources, property transactions, or benefit reporting can increase the likelihood of questions, even when everything has been done correctly.

By knowing the potential triggers and keeping clear documentation, you can protect your finances and support a stress-free retirement.
