Can I appeal my 2026 Quarterly Estimated Taxes?

[MelindaS1 · Accepted solution]

There's no need to appeal anything, you can follow these steps to update your projected income and withholding details for next year's estimated tax vouchers (Form 1040-ES) :

1. Open or continue your return.
2. Navigate to the 1040-ES section:
   • TurboTax Online/Mobile: Go to the 1040-ES screen under Other Tax Situations.
   • TurboTax Desktop: Search for 1040-es and select the Jump to link or,
     • Go to Federal Taxes.
     • Go to Other Tax Situations.
     • Under Other Tax Forms, select Start or Update next to Form W-4 and estimated taxes.

Note: the rules for avoiding an underpayment penalty of federal estimated taxes, in most cases, are to pay 90% of the estimated tax due before the end of the year, or 100% of your prior-year tax. The program follows this logic in estimating your quarterly payments for the following year. Learn more (IRS Form 2210 Instructions).
