Overpayment and Application Options

Paying your taxes twice can happen for various reasons. If you find yourself in this situation, it’s important to understand your options for claiming a refund or applying the overpayment to future tax liabilities.


When you unintentionally pay more taxes than you owe, the excess amount is considered an overpayment.

  • Automatic Refund: If the overpayment is less than $1,000 ($2,000 for married couples filing jointly), the IRS will automatically send you a refund.
  • Request a Refund: For overpayments greater than the above thresholds, you must file an amended tax return (Form 1040-X) to claim your refund.

Application Options

If you don’t wish to receive a refund, you can apply the overpayment to:

  • Estimate Next Year’s Taxes: You can apply the overpayment to your estimated tax liability for the following year.
  • Apply to Other Debts: If you owe other federal debts, such as back taxes or student loans, you can apply the overpayment to those debts.

You can indicate your application preference by completing Form 843, “Claim for Refund and Request for Application of Overpayment.” You can also specify if you want the overpayment to be applied to:
