Idaho Tax Planning Tip

Idaho’s flat 5.8% income tax rate simplifies planning compared to states with progressive brackets, but it still adds up for high-income S-Corp owners. Idaho conforms closely to federal tax provisions, so most federal deductions flow through without adjustment. Take advantage of Idaho’s investment tax credit for qualifying new business property — it’s 3% of the cost basis and can offset state tax liability dollar-for-dollar.

Idaho Falls is home to 3,200+ small businesses and a population of 68,001. From Nuclear Energy, Healthcare, Agriculture to professional services, Idaho Falls business owners need CPAs who understand Idaho National Laboratory contractors face unique federal procurement accounting requirements and security clearance-related compensation structures that complicate tax planning and can provide year-round tax planning — not just compliance.
