Last-Minute Tax Prep Checklist: What to Do Before You File

1. Gather All Required Tax Documents

Before you file, make sure you have all necessary paperwork in one place. Common documents include:

  • W-2s from employers
  • 1099 forms (freelance income, interest, dividends)
  • Mortgage interest statement (Form 1098)
  • Student loan interest statement
  • Property tax records
  • Retirement income statements
  • Health insurance forms (if applicable)

Why it matters: Missing documents can delay your return or trigger IRS notices later.

2. Review Personal Information Carefully

Double-check:

  • Social Security numbers for you and dependents
  • Correct spelling of names
  • Current address and bank account details

Even small errors can cause processing delays or rejected returns.

3. Check Eligibility for Deductions and Credits

Even at the last minute, it’s worth reviewing potential tax savings. Look for:

  • Standard vs. itemized deduction decision
  • Child Tax Credit or dependent credits
  • Education credits or deductions
  • Retirement contributions
  • Charitable donations

Many filers miss credits simply because they assume they don’t qualify—review carefully.

4. Confirm Income Is Fully Reported

Make sure all income sources are included, even side gigs or small freelance jobs. Commonly missed income:

  • Gig or contract work
  • Interest from savings or CDs
  • Investment dividends
  • Digital payments reported on 1099-K forms

Leaving out income can increase the risk of IRS follow-up.

5. Decide How You’ll File

At the last minute, choosing the right filing method matters. Options include:

  • IRS Free File or tax software
  • A trusted tax professional
  • Filing an extension if needed

If you file an extension, remember: An extension gives you more time to file, not more time to pay.

6. Prepare for Payment (If You Owe)

If you owe taxes:

  • Review payment options (direct pay, installment plans)
  • Avoid high-interest credit cards if possible
  • Pay as much as you can by the deadline to reduce penalties

Credit union tip: Budgeting tools can help you plan for tax payments without disrupting other financial goals.

7. Set Up Direct Deposit for Refunds

If you’re expecting a refund:

  • Choose direct deposit for faster access
  • Double-check routing and account numbers

Direct deposit is typically the fastest and safest way to receive your refund.

8. Keep Copies of Everything

Before hitting submit:

  • Save digital copies of your return
  • Store receipts and supporting documents
  • Keep records for at least three years

Good records protect you if questions arise later.

9. Watch Out for Common Last-Minute Mistakes

Avoid these frequent errors:

  • Rushing through data entry
  • Forgetting to sign the return
  • Missing estimated payments
  • Filing under the wrong status
  • Overlooking state tax requirements

A quick final review can prevent big headaches.

10. Plan Ahead for Next Year

Once your return is filed, take a moment to make next year easier:

  • Adjust withholding if needed
  • Set up a tax savings fund
  • Organize documents digitally
  • Schedule mid-year check-ins

Credit union advantage: Many members use savings tools to set aside small amounts year-round for taxes.
