Business provisions added back
The personal income tax and business corporation tax regulations both decouple from:
- The section 163(j) business interest change, with any extra federal deduction added back.
- Section 174A domestic research expensing, added back and recovered under Rhode Island rules at 20% a year.
- The higher section 179(b) expensing limits.
- The sound recording production provisions in sections 168(k) and 181.
