Does TT calculate Estimated Quarterly Payments?

Yes. 

 

The Form 1040-ES for making quarterly payments is currently expected to become available in TurboTax on February 25, 2026. However, if you want to make a payment now, you can pay directly online to IRS.

 

To calculate estimated taxes and prepare Forms 1040-ES in TurboTax Online:

 

1. With your tax return open, search for 1040-es (be sure to include the dash) and select the Jump to link
2. Answer No to the question Do you want to change your W-4 withholdings for 2026?
3. Answer the questions about things like your 2026 filing status, income, and deductions
4. Eventually, you'll come to the Print Vouchers? screen. Answer Yes and we'll include your 2026 1040-ES payment vouchers when you print a copy of your return later

 

In TurboTax Desktop, select Other Tax Situations, then Form W-4 and Estimated Taxes.

 

In addition, TurboTax's TaxCaster is available without opening your return and will estimate your total taxes. It is currently set to calculate 2025 taxes but you could use your 2026 estimated income and deductions to get a good estimate for 2026.

 

You can also use the IRS Withholding Estimator to calculate amounts to be withheld from wages.

 

Have this ready:

• Paystubs for all jobs (spouse too)
• Other income info (side jobs, self-employment, investments, etc.)
• Most recent tax return
