Avoiding the Most Common Tax Filing Mistakes
Even small mistakes on your tax return can cost you money or trigger an IRS notice. Here are the most common errors and how to avoid them.
Common Tax Filing Mistakes
1. Incorrect Social Security Numbers
The most fundamental error. Double-check every SSN for yourself, your spouse, and all dependents.
2. Wrong Filing Status
Using Single instead of Head of Household, or filing MFJ when MFS would be better.
3. Missing Income
Forgetting W-2s, 1099s, side income, or bank interest. The IRS matches all income forms it receives.
4. Math Errors
Easily caught by tax software, but still common on paper returns. The IRS will correct math errors.
5. Missing Deductions and Credits
- Not claiming the EITC when eligible
- Missing education credits
- Forgetting charitable contributions
- Ignoring retirement contribution deductions
6. Not Reporting All Crypto Activity
Every crypto sale, trade, or payment is potentially taxable.
7. Ignoring Estimated Taxes
Self-employed workers who don't pay quarterly estimates face penalties.
8. Using the Wrong Bank Account
Double-check your routing and account number for direct deposit.
9. Not Signing the Return
An unsigned return is not valid.
10. Filing Early Without All Forms
Wait until you have all W-2s and 1099s — usually by January 31.
