A friendly tax nag reminder: Don’t miss June 16 estimated tax due date

I know I nagged reminded folks who face estimated tax payments of the June 16 deadline just last week in my monthly tax moves post.

Well, I’m back nagging reminding all y’all again. Sorry, not sorry.

As the hubby knows, my penchant for nagging repeating myself is because I care. It’s also because we also make estimated tax payments four times a year, so the process is on my mind.

June 16 payment date: The June estimated tax due date is officially the 15th, but since that’s on a Sunday — Father’s Day, just in case you need a reminder about that, too 😊 — the second estimated tax payment is due Monday, June 16.

The amount due technically covers income earned in April and May that wasn’t subject to withholding.

For most estimated taxpayers, that will be the same amount as your first 1040-ES payment back in April.

That’s because most estimated taxpayers make a good estimate of this year’s earnings that aren’t subject to withholding, figure the tax due, and divide it by four.

They then send those amounts to the Internal Revenue Service to meet the mid-month due dates each April, June, September, and January of the next year.

The flow chart below from IRS Publication 505, Tax Withholding and Estimated Tax, offers a visual depiction of when you need to make estimated tax payments.

Safe harbors to avoiding penalties: Making the correct estimated tax payment amounts and on time is critical. Mess up either and you’ll face penalties.

To avoid that unwanted circumstance, your total estimated tax paid must be at least 90 percent of the tax you’ll ultimately owe when you file next year.

If your non-withheld earnings are uneven throughout the year, you can use the annualized income installment method to precisely figure your estimated tax amounts for each quarter. This method helps with cash flow, but does take more work and record keeping.

Then there are those of us who avoid penalty charges by taking the easiest estimated tax payment route. We sidestep tax guesstimating or continual monthly figuring by simply paying our prior year’s full tax liability in four equal estimated tax amounts.

Meeting this safe harbor of paying 100 percent of last year’s tax liability in four equal payments means, regardless of what your eventual 2025 tax bill is, you won’t face any estimated tax underpayment penalties.

Total tax, not remaining tax due: Note that this is 100 percent your total tax bill last year, found on line 24 of your Form 1040.

It is not simply what you ended up owing Uncle Sam when your filled out your return with all your tax payments, withholding or otherwise, considered.

Note, too, that your safe harbor percentage is larger is you make more money. It goes to 110 percent of your prior year’s total tax if your adjusted gross income in 2024 was more than $150,000 ($75,000 if your filing status for 2025 is married filing a separate return).

Ways to paying estimated taxes: Once you know what you need to pay on June 16, the easiest way to do that, for both you and the IRS, is electronically.

The IRS offers a variety of options.

If, however, you prefer paper, the IRS still accepts checks and money orders. Make the estimated tax amount payable to the “United States Treasury.” You also need to download and send Form 1040-ES with your check or money order.

TAX-SAVVY WAYS 
TO WRAP UP 2026

It’s over! With October’s extended filing deadline behind us, it is now time to focus on year-end moves to reduce your 2026 tax bill. 

You’ll find ways to do just that on the Tax Tips page (see the More Tax Posts drop-down menu at the top of the blog), as well as the separate tax tip pages for each month, notably October through December. If you’re on the Tax Tips page, you’ll find a monthly list at the end of this column. If you’re on another blog page, you can head straight to the October tips; at the bottom of that tips page you’ll find links to all the other 11 months’ collections of tax advice.

Not to spoil what you’ll find in that tax advice, but it does cover such things as tax deductions for charitable donations, investment moves that could reduce tax due, and ways to max out your tax-favored retirement savings. 

Finally, as the year winds down, things get hectic. There are lots of other things to occupy our time, like the much more fun upcoming holidays. But don’t lose sight of taxes, since timing is key. To be of use, most tax moves must be made by the end of the tax year. That’s Thursday, Dec. 31, which also is the last business day of the year. 

So that you don’t miss that final tax year deadline, also keep an eye on the countdown clock below. It will keep you on top of just how much time is left to make important, tax-saving moves. (Note: I’m in the Central Time Zone, so adjust accordingly for where you live.)
