You filed your 2025 return in April. You’re done, right? Maybe even got a refund. So surely you can shred that pile of paperwork now. Not so fast.
The “3-Year Rule” Is Only Half the Story
Here’s what most people get wrong: the IRS standard audit window is 3 years from your filing date. File your 2025 return on April 15, 2026, and the IRS technically has until April 15, 2029 to come knocking. But if you underreported income by more than 25% of your gross income — even accidentally, say a forgotten freelance 1099 — that window stretches to 6 years. Your 2022 documents filed in April 2023 could still be fair game through April 2029. That’s not a typo.
And “got my refund” doesn’t mean you’re cleared. Receiving a refund does not close the audit window. I see this misconception constantly, and it costs people.
The 3 Documents You Actually Cannot Toss Yet
Your W-2 forms. Keep every W-2 until retirement age, full stop. Social Security calculates your benefits using lifetime earnings records, and if SSA’s numbers don’t match yours, you’ll want the paper proof. H&R Block advises keeping retirement-related tax forms for 7 years after an account fully closes — same logic applies here.
Your 1099s. including the new 1099-DA. Starting in 2026, brokers like Coinbase and Kraken are issuing the brand-new Form 1099-DA for your 2025 crypto and digital asset transactions. This is the IRS’s first year of automated matching on crypto activity. The IRS’s IRIS system cross-checks every 1099 it receives against your filed return; a mismatch triggers a CP2000 notice before any human auditor even sees your file. Keep every 1099 you received. Every. Single. One.
Your supporting documentation for income. Here’s the 2026 twist nobody’s talking about: the One Big Beautiful Bill Act raised the 1099-NEC reporting threshold from $600 to $2,000 starting January 1, 2026. Translation: if you did freelance work this year and earned $1,400, no 1099 is coming. But you still owe taxes on that income. Now you’re your own recordkeeper, bank statements, invoices, payment app screenshots. April Walker, Senior Manager for Tax Practice & Ethics at AICPA, told CNBC in February 2026 that incomplete income reporting is exactly what triggers automated IRS flags.
The Honest Truth About IRS Audits Right Now
Yes, the IRS lost over 20% of its workforce since early 2025, and its 2026 budget was cut 9%. Fewer human auditors sounds reassuring. But the National Taxpayer Advocate warned Congress in January 2026 that this actually makes things harder for average filers. because the agency is leaning harder on automated matching to compensate. So while high-income audits dropped sharply, the CP2000 computer-generated notices hitting ordinary taxpayers? Still very much a thing.
So here’s what I’d actually do: download your IRS Tax Transcript from IRS.gov right now. It shows every W-2 and 1099 the agency has on file under your name. If anything looks off before a notice arrives, you’ll be glad you checked, and even gladder you kept the documents to prove it.
