Filed Without SALT?
You Can Still Get That Money Back

Millions of Americans file their taxes without claiming every deduction they’re owed. If you missed the new $40,000 SALT deduction, filing an amended return could put thousands of dollars back in your pocket.

✅ Good News: You Have Up to 3 Years to Amend

The IRS allows you to file an amended return within 3 years of your original filing date. For your 2025 taxes (filed in 2026), you have until April 15, 2029 to amend — but acting sooner means getting your refund sooner.

Did You Miss the SALT Deduction? Here’s How to Know

You may want to file an amended return if you filed your 2025 taxes and any of these apply: you took the standard deduction without checking if itemizing would save more, you claimed SALT but used the old $10,000 cap instead of the new $40,000 cap, you forgot to include property taxes or local income taxes in your SALT total, or a tax preparer filed your return without accounting for the new OBBBA rules.

Filing Form 1040-X — Step by Step

1
Get Form 1040-X

Form 1040-X is the IRS Amended U.S. Individual Income Tax Return. You can download it free from IRS.gov, or your tax software (TurboTax, H&R Block, TaxAct) can generate it automatically when you tell it you’re amending a prior return.

💡 If you e-filed your original return, you can now e-file the 1040-X as well — much faster than mailing a paper form.
2
Recalculate Your Deductions

Go back to Schedule A and recalculate your itemized deductions with the correct SALT amount (capped at $40,000). Compare the total to your standard deduction. If itemizing gives you a higher deduction, that’s the number you’ll use in your amended return.

💡 Use our free calculator to quickly figure out your correct SALT amount.
3
Complete Form 1040-X

The 1040-X has three columns: Column A shows the original amounts you filed, Column B shows the changes, and Column C shows the corrected amounts. In the explanation section at the bottom, write: “Amending to claim SALT deduction under new $40,000 cap per OBBBA.”

💡 Attach the corrected Schedule A to your 1040-X. Don’t attach your entire original return — only the schedules that changed.
4
File and Wait for Your Refund

E-file your 1040-X if possible — it’s faster and you can track the status. If mailing a paper form, send it to the IRS address listed in the 1040-X instructions for your state. The IRS typically processes amended returns in 8–12 weeks.

💡 You can track your amended return status at IRS.gov using the “Where’s My Amended Return?” tool — available 3 weeks after filing.

Timeline: From Filing to Refund

Day 1: You file Form 1040-X electronically
3 weeks later: Amended return appears in IRS tracking system
8–12 weeks: IRS processes your amended return
After processing: Refund issued via direct deposit or check
Up to 3 years: Maximum window to file an amendment for 2025 taxes

Frequently Asked Questions

Will amending my return trigger an audit? +
Filing an amended return does not automatically trigger an audit. The IRS processes millions of 1040-X forms every year. As long as your amendment is accurate and well-documented, there’s no reason for concern.
Can I amend a return I filed 2 years ago? +
Yes. You have 3 years from the original filing date (or 2 years from the date you paid the tax, whichever is later) to file an amendment and claim a refund. For 2023 taxes filed in April 2024, you have until April 2027.
What if my state return also needs to be amended? +
In most cases, if you amend your federal return, you should also amend your state return — since most states use federal adjusted gross income as the starting point. Each state has its own amendment form, usually similar to the federal 1040-X.
How long does it take to get the refund from an amended return? +
The IRS typically takes 8 to 12 weeks to process an amended return, sometimes longer during busy periods. E-filing is significantly faster than mailing a paper form. You can check the status using the IRS “Where’s My Amended Return?” tool.
Is it worth hiring a tax professional to amend my return? +
If the potential refund is large — say, $3,000 or more — hiring a CPA or enrolled agent to amend your return can be worth the cost. They can also catch other deductions you may have missed. Tax preparation fees are themselves tax-deductible in some circumstances.
