Computer scientists’ tax code algorithm could make it easier for IRS to catch partnership tax cheats

October 10, 2015

Computers and taxes are inseparable.

Most of us use our computers to file our taxes every year.

Taxes-Computer-Keyboard

The Internal Revenue Service relies on its computers, which it keeps telling Congress it needs money to upgrade, to process those millions of electronically completed and filed returns.

Now some computer scientists are working on an algorithm that could help catch some tax cheats.

Partnership tax shelter troubles: Specifically, researchers from the Massachusetts Institute of Technology and the nonprofit technology research and development organization Mitre Corporation, are focusing on a certain type of tax shelter used by partnerships.

"We see the tax code as a calculator," Jacob Rosen, a researcher at MIT, told the New York Times. "There are lots of extraordinarily smart people who take individual parts of the tax code and recombine them in complex transactions to construct something not intended by the law."

Bad basis, bogus deduction: Rosen and his fellow computer experts are concentrating on an installment sales shelter that artificially inflates the basis value of an asset on a tax return to wipe out taxable gains when the asset is sold.

To nab tax cheats who use these and other types of tax evasion techniques, the IRS now uses data mining. Basically, the agency collects data from filed tax returns and analyzes it for patterns.

The data mining approach, however, depends on the tax investigators already having some kind of evidence of possible illegal tax activity, such as a suspicious deduction on a return.

AI as preemptive tax filter: The artificial intelligence approach, however, doesn't need the preexisting evidence. Instead, it focuses on rule mining.

In rule mining, individual tax code regulations are lined up against one another to determine if they can be used collectively to create a sophisticated tax dodge.

"It's incredibly difficult to have a computer algorithm that duplicates the enormous creativity of taxpayers, but it's very promising," Robert A. Green, a tax professor at Cornell Law School who read the MIT/Mitre paper, said.

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.)
