The Trump administration wants taxpayers to check their paychecks for the tax cuts.

The Treasury again issued an appeal to workers Wednesday to double-check the amount withheld from their paychecks using the IRS’ updated calculator, to make sure that it is correct.

“This is a pivotal and exciting time for American workers,” Treasury Secretary Steven Mnuchin said in a statement. “The ‘paycheck checkup’ will allow employees to keep more of their hard earned money, which is why we passed the Tax Cuts and Jobs Act.”

Mnuchin also issued a direct-to-camera video recommending the check-up.

The Treasury and IRS rolled out the new calculator in February, asking for taxpayers to double-check their withholding after the new tax tables reflecting the Trump tax cuts were issued.

In addition to the problems that could crop up if people overpay or underpay throughout the year, the Trump administration and Republicans have political reasons for wanting people to check their paychecks.

Most people should see higher take-home pay this year thanks to the GOP tax cuts. But so far, few are noticing them.
