A majority of Massachusetts homeowners could save big due to new higher state-and-local-tax deduction caps, according to a recent report from Redfin.

President Trump’s One Big Beautiful Bill Act raised SALT-deduction caps to $40,000 from $10,000 for homeowners itemizing their taxes. Redfin used local tax revenue, home value and income data to determine how much typical homeowners could expect to deduct.

In Massachusetts, over 85% of residents stand to benefit from the adjustments. The median SALT deduction in Massachusetts now sits at $25,979, and qualifying Bay Staters will save a median of $3,835.

In some states with lower property taxes and property values, only a few residents will see savings, however. In Tennessee, the share of homeowners expected to benefit is only 1%.

Notably, these statistics reflect how many households could save, but not all will. Many homeowners opt for the standard tax deduction.

“Benefits vary so widely because the mix of home values, property taxes and income taxes looks very different depending on where you live,” said Redfin Senior Economist Asad Khan. “In states with both high home values and high taxes, most homeowners are now able to deduct more than they could under the old $10,000 cap. In lower-tax states — or states with no income tax — the impact is smaller, even for people with expensive homes.”
