Fifty years ago this weekend, two Apollo 11 crew members became the first people to set foot on the moon.

In doing so, the National Aeronautics and Space Administration (NASA) fulfilled the dream/challenge that President John F. Kennedy had issued in 1961 of "landing a man on the moon and returning him safely to the earth."

While Kennedy didn't live to see that historic accomplishment, another event last week made me think of JFK and another first he achieved.

Kennedy was the first president to ever visit the Internal Revenue Service. The IRS commissioner who welcomed JFK was Mortimer Caplin.

Caplin, the 34th IRS commissioner, passed away on July 15 at his home in Chevy Chase, Maryland. He was 103.

"Mr. Caplin brought political savvy and an extrovert’s flair to a somber profession mostly characterized by its fascination with loopholes and number crunching," noted The Washington Post in its obituary of the "charismatic and hard-driving" Caplin.

Fond IRS memories: The current head of the IRS also had some thoughts about the man who led the agency from 1961 to 1964.

IRS Commissioner Chuck Rettig issued the following statement about Caplin:

     The passing of Mort Caplin, the 34th Commissioner of the IRS, is a tremendous loss for our employees, the tax community and the nation. Mort had an amazing personal story and an amazing career of service to our nation before, during and after his time at the IRS. He served as a beachmaster at Omaha Beach during the Normandy Invasion in World War II and later led the IRS from 1961-1964. He then spent more than half a century doing legendary work in the nation’s tax community, including founding the Caplin and Drysdale law firm.

     One of my favorite citations is from IRS Revenue Procedure 1964-22, which was issued by then-Commissioner Caplin. This guidance notes that "it is the duty of the Service to … correctly [apply] the laws enacted by Congress … and to perform this work in a fair and impartial manner, with neither a government nor a taxpayer point of view." The concept behind that quote is just as relevant now as it was when he signed it as Commissioner, and it is a reflection of the enduring impact he will continue to have on the IRS and the entire tax community.

     Mort's message to taxpayers, enclosed with their 1961 tax returns, conveyed an important concept that also still rings true. "Taxes are necessary for the kind of orderly government which will preserve America and its way of life," he wrote. Indeed, throughout Mort's incredible life, his service and dedication personally embodied what it takes to preserve America and its way of life. He will be missed.

Kudos for Caplin: As we celebrate NASA's and our country's accomplishments this weekend, it's fitting we also recognize Caplin's life. He was dedicated to the federal agency that collects the funds required for all government agency goals and duties.

In fact, Caplin still supported the IRS long after he officially left his position with the agency. In 2015, he was one of 7 former IRS commissioners who chastised Congress for slashing the IRS budget.

The continued IRS advocacy of Caplin and those who also held the top IRS position is a good reminder that we all must work together to continue U.S. progress, be it technological, scientific, humanitarian and fiscal.

That's why this weekend's By the Numbers honor is 34, saluting IRS Commissioner Mortimer Caplin.

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.)
