Property tax: payment and collection; eligibility for a summer property tax deferment; modify. Amends sec. 51 of 1893 PA 206 (MCL 211.51).

HB 5225 modifies Michigan's property tax deferment program for summer property taxes, primarily affecting eligible homeowners aged 62+ or with specific disabilities (like blindness or veterans' status) and agricultural property owners. It updates income thresholds for deferment eligibility - current limits cap household income at $60,000 (adjusted annually for inflation after 2026) - and requires agricultural owners to meet gross receipts criteria. The bill mandates local treasurers to publish deferment notices, provide form assistance, and include deferred tax amounts in December tax statements, with payments due by February 15 without penalties. It also clarifies that agricultural deferment eligibility requires prior qualification before forming business entities like LLCs.
