This webinar will review state responses to the One Big Beautiful Bill Act (OBBBA) and its impact on state tax liability for businesses and individuals. Our panel of veteran multistate practitioners will discuss key provisions that affect state tax and provide insights to manage state income tax issues arising from the new Act.
Description
The OBBBA transformed federal tax legislation, which compels states to modify or adopt corresponding legislation. States incorporate federal guidelines using one of three methods: rolling, fixed, or selective conformity. Rolling conformity states adopt federal changes when passed, while fixed conformity states may follow the new legislation as of a specific date. Selective conformity states consider the federal provisions individually.
The restoration of 168(k) 100% bonus depreciation and the carryback allowances for R&E expenditures could prove costly. Fixed conformity states may decide to decouple from certain federal provisions. Timing is key. States may not finalize guidance in a timely manner, and the legislation passed could be retroactive. Analyzing taxpayers' multistate tax obligations and responding effectively will be problematic for SALT practitioners.
Listen as our panel of proficient state and local tax professionals analyzes the new provisions under OBBBA and offers insights to handle multistate compliance for SALT advisers.
