Tax time, always busy for Minnesota's thousands of accountants and tax attorneys, promises more headaches than usual this year for preparers and clients alike.
The biggest tax overhaul in decades, a state-federal tax code disconnect that further complicates Minnesota filings and potential Internal Revenue Service delays after a partial government shutdown have industry veterans bracing for a hectic tax season.
"My sense is that [Minnesota], by not adopting the federal changes, has got to be one of the most complicated states in the country to deal with," said Mark Salsbury, a partner who focuses on tax planning and merger-and-acquisition transactions at the Ballard Spahr law firm. "It's a nightmare."
The tax filing season begins Monday, when the IRS is scheduled to start processing returns for individuals. Many accountants are prepared to work long hours to try to get their clients' forms in order ahead of the April 15 deadline.
"They've kind of rewritten the book on a lot of this in that we have to learn as stuff is either in proposed stages or even final stages along with a lot of new forms, documentation," said Tyler Hess, a principal who manages the tax practice at CliftonLarsonAllen's Minneapolis office. "We are still learning."
In late 2017, President Donald Trump signed the most sweeping federal tax overhaul since the 1980s, spelling dramatic changes in the way individuals and corporations file their taxes.
The bill lowered tax rates, especially for corporations, and changed the tax break landscape for many individuals by: changing certain credits, doubling the standard deduction and capping deductions for local property and income tax or sales tax, which packs a bigger punch in higher tax states like Minnesota.
Last year, Minnesota became one of a handful of states not to enact legislation to conform to new federal tax provisions when Gov. Mark Dayton vetoed a tax bill that capped a bitter legislative session.
