Pay your 4th estimated tax amount by Jan. 15

January 12, 2026

I’m getting nagged by the Internal Revenue Service, so I decided to do the same to you.

The reminder (the IRS uses the same term I do when I point things out to the hubby 😉) that my estimated tax payment is scheduled for Thursday, Jan. 15, showed up in today’s email.

Uncle Sam wants to make sure I have enough in my bank account for its Electronic Federal Tax Payment System (EFTPS) system to automatically complete the transaction.

Good news for the IRS. I do.

Now to my reminder to y’all readers of the ol’ blog.

Final 2025 tax payment due: If you must make this January estimated tax payment, the last one for the 2025 tax year, and haven’t yet made arrangements to do so, get to it!

Okay, you can skip it if you plan to file your 2025 return and pay any tax due by Jan. 31. But if you’re like me, you’ll still be getting tax statements by then, essentially making it impossible to accurately fill out your Form 1040 that soon.

So don’t miss this week’s Jan. 15 estimated tax payment due date. If you do, and you end up owing more than $1,000 when you do eventually file your return, you could be hit with a tax penalty and interest.

Estimated tax added info: And for folks new to the estimated tax payment process, you might want to check out my post on tax moves to make this January as you get ready to write your 1040-ES check, or more likely, set up your e-payment.

January tax move #3 discusses estimated taxes, and has links to other posts with more information on the way the IRS collects as quickly as possibly the tax due on income that isn’t subject to withholding.

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.)
