TAXATION – Amends and adds to existing law to revise provisions regarding the taxation of partnership income.

H 733 revises Idaho's tax code for partnerships and S corporations (now called "affected business entities") by requiring these entities to pay tax on behalf of non-resident members instead of individual members filing returns. The bill adds new rules for calculating tax based on Idaho-sourced income, sets deadlines for annual elections to qualify as an affected business entity, and creates a new section (63-3070) to handle partnership income and federal adjustments. Non-resident members of such entities will not need to file individual tax returns if the entity pays the tax and reports it. The bill also updates technical provisions for tax notices, deadlines, and credit adjustments. These changes streamline tax collection for businesses with non-resident owners while maintaining Idaho's corporate tax rate for entity-level payments.
