An Act amending the act of March 4, 1971 (P.L.6, No.2), known as the Tax Reform Code of 1971, in mutual thrift institutions tax, further providing for imposition, report and payment of tax and exemptions.

SB 576 amends Pennsylvania's tax code for mutual thrift institutions, such as credit unions, by adjusting their annual tax rates on taxable net income. Starting in 2025, the tax rate will gradually decrease from 7.95% to 4.99% over seven years, with specific rates set for each year through 2031. The bill also revises the net loss carryover rule, allowing institutions to deduct losses from the previous ten years (instead of three) when calculating current tax, but the deduction cannot exceed the current year's net income. Mutual thrift institutions must report and pay taxes annually by April 15 under these updated rules.
