Tax season is stressful — a blur of deadlines, confusing forms, and caffeine-fueled panic. We see it all. And every single year, taxpayers make the same avoidable, costly mistakes.
These slip-ups don’t just cause headaches. They can delay your refund, cost you credits, or even trigger a love letter from the IRS.
Here’s a peek at the top five mistakes we see year after year and how to dodge them.
1. Simple Typos and Bad Data
The number one reason a tax return gets rejected? Typos. One wrong digit in a Social Security number or bank account can stop your return cold or send your refund into the void.
How to avoid it: Proofread every number and name before you hit “Submit.” It’s tedious, but cheaper than waiting months for a lost refund.
2. Forgetting Income
The IRS already knows what you earned. Their computers match your return against every W-2 and Form 1099 filed under your name. Miss one, and they’ll catch it later, with interest.
How to avoid it: Wait until you’ve received every W-2 and 1099 before filing. That includes income from side gigs, bank interest, and investments.
3. Choosing the Wrong Filing Status
Your filing status affects everything — your standard deduction, brackets, and eligibility for credits. The biggest mistake we see? Filing “Single” when you qualify for “Head of Household.”
How to avoid it: Review the rules each year, especially if you’ve had a major life change (marriage, divorce, new dependent).
4. Missing Credits and Deductions
This is the equivalent of leaving free money on the table. Credits like the Earned Income Tax Credit, Child and Dependent Care Credit, and American Opportunity Credit can dramatically lower your bill.
How to avoid it: Slow down. Read every question carefully in your tax software. Those “boring” life details unlock real savings.
5. Filing Late (or Not at All)
Some taxpayers skip filing when they can’t pay. That’s a huge mistake. The penalty for not filing can be 10x higher than the penalty for not paying.
How to avoid it: Always file by the deadline (or file an extension). If you owe, file anyway. The IRS is surprisingly flexible with payment plans if you communicate early.
Tax season doesn’t have to be a nightmare. Avoid these traps, file accurately, and keep the IRS off your back, so you can spend your spring doing literally anything else.
