Does payment of estimated tax. as recommended by TurboTax, guarantee that I will not be subject to a penalty for underwithholding?

[DianeC958 · Accepted solution]

Yes, if the information you put into TurboTax for your income and other withholding is accurate.

The safest option to avoid an underpayment penalty is to aim for "100 percent of your previous year's taxes." If your previous year's adjusted gross income was more than $150,000 (or $75,000 for those who are married and filing separate returns last year), you will have to pay in 110 percent of your previous year's taxes to satisfy the "safe-harbor" requirement. If you satisfy either test, you won't have to pay an estimated tax penalty, no matter how much tax you owe with your tax return.

If you expect your income this year to be less than last year and you don't want to pay more taxes than you think you will owe at year end, you can choose to pay 90 percent of your estimated current year tax bill. If the total of your estimated payments and withholding add up to less than 90 percent of what you owe, you may face an underpayment penalty. So you may want to avoid cutting your payments too close to the 90 percent mark to give yourself a little safety net.

If you expect your income this year to be more than your income last year and you don't want to end up owing any taxes when you file your return, try to make enough estimated tax payments to pay 100 percent of your current year income tax liability.

Estimated Taxes: How to Determine What to Pay and When

My employer withholds federal tax from my compensation.  And I received misc. compensation in Quarter 4. I understand the rule is:  To avoid a penalty, you must pay (i) at least 90% of the tax you owe via withholding or estimated tax payments or (ii) 110% of the tax shown on last year’s return, whichever is smaller.  With employer withholding and estimated tax payment for Quarter 4 (before Jan. 15, 2025), I paid over 90% of my 2024 tax liability.  However, TurboTax is forcing me to pay a penalty because I don't meet the 110% rule. It won't even apply the 110% rule.  And I cannot override it.

Am I missing something or is this a TurboTax flaw?

You might be able to eliminate it or at least reduce it.  You can go to Federal Taxes tab or Personal tab, under Other Tax Situations and select Start by the Underpayment Penalties. You will answer a series of questions that may reduce or eliminate the penalty. Or you can elect to have the IRS figure the penalty for you.  It's form 2210.

It's under

Federal or Personal (for Home & Business Desktop)

Other Tax Situations

Additional Tax Payments

Underpayment Penalties - Click the Start or update button

If you have the desktop program you can switch to Forms Mode (click forms in the upper right (left for Mac)) and open the 2210 form.  If the 2210 doesn't show up in the left column, click on Open Forms at the top of the left column.  Type 2210 in the search box and open the 2210 form.  Check box C to let the IRS calculate it.

You can even have a penalty if you are getting a refund.  I have.
