Can TurboTax calculate next year's federal estimated taxes?
Yes, if you’re at risk for an underpayment penalty next year, based on your 2016 information, we’ll automatically calculate estimated tax payments and prepare 1040-ES vouchers for you.
You can also go directly to the estimated tax section by typing 1040-es in the search box (include the dash, lower case or capital letters okay) and selecting the “Jump to” link. Answer Yes to the question, Do you want to change your W-4 withholdings for 2017? (This allows you to give us information we can use to recommend whether you should make estimated tax payments. You can change your mind later.) On the following screens, review your W-4 withholdings and answer the questions. We'll calculate estimated tax payments for next year. If payments are necessary to avoid an underpayment penalty, we'll ask you to print out estimated tax vouchers.
