An error in the tax bill approved by the Legislature in May will have lawmakers scrambling next year to avoid Minnesotans having to pay higher income taxes.

Minnesota Revenue Commissioner Paul Marquart and House and Senate tax committee chairs Sen. Ann Rest, DFL-New Hope, and Rep. Aisha Gomez, DFL-Minneapolis, acknowledged the error in a statement Friday. The statement also said they had an agreement to fix it when the Legislature reconvenes in February 2024.

If lawmakers fix the error next year it shouldn’t impact what taxpayers owe, the statement said. Each session, lawmakers fix errors they find in laws they’ve passed and sometimes those mistakes have the potential to cost Minnesotans money.

The latest tax bill uses the wrong amounts for the standard deduction married- and single-filers can claim. If lawmakers don’t fix it about 2.3 million Minnesota taxpayers could pay an additional $352 million, a spokesman for the state Department of Revenue said.

The error was first reported by the news website MinnPost.

In 2019, the Legislature doubled the standard deduction to $24,400 for couples and $12,200 for singles and tied it to inflation. The 2023 standard deduction for couples is now $27,650 and $13,825 for a individuals.

The tax bill recently OK’d by lawmakers includes $3 billion worth of changes, using part of the state’s historic $17.5 billion budget surplus. The latest state budget that went into effect July 1 spends $71.5 billion over the next two years.

This fall, taxpayers earning less than $75,000 and couples making under $150,000 will get rebate checks worth about $260 per per taxpayer and dependents. That will cost about $1.1 billion.

Seniors earning less than $100,000 per couple or $78,000 for singles will pay no state taxes on Social Security, which will cut state revenues by about $500 million in the new two-year budget. There’s an expanded child tax credit and modified renters credit.

The Democratic-Farmer-Labor Party controlled Legislature also raised taxes on corporations and higher earners. They also approved 1 percent worth of new sales taxes in the Twin Cities metro, a 10 percent tax on hemp and cannabis products and a 0.7 percent payroll tax that begins in 2025 to fund a universal paid leave program.
