Georgia corporate tax guide for CFOs and CPAs: 5.39% Corporate Income Tax, 100% Single Sales apportionment, $250,000 economic nexus threshold, IRC §174 R&D conformity, and §168(k) bonus depreciation rules.
1. How Georgia Apportionment & Economic Nexus Impact ASC 740 Tax Provisions
For multi-state C-Corporations and SaaS companies selling into Georgia (GA), exceeding $250,000 in annual GA-sourced receipts (or maintaining remote W-2 employees inside the state) establishes nexus under Georgia's Corporate Income Tax. Under 100% Single Sales apportionment and Market-Based rules, SaaS subscription revenue is sourced to Georgia based on where the customer receives the benefit of the software.
2. Georgia Federal-to-State Tax Base Modifications (§174 R&D & §168(k) Bonus Depreciation)
- IRC §174 R&D Capitalization Rule in Georgia: Georgia DECOUPLES from federal TCJA IRC §174 capitalization! Taxpayers filing in Georgia may deduct 100% of current-year domestic R&D expenses on their GA return via a state subtraction modification—dramatically lowering GA taxable income compared to Federal Form 1120.
- IRC §168(k) Bonus Depreciation Rule in Georgia: Georgia decouples from federal IRC §168(k) bonus depreciation. Corporate taxpayers must add back federal bonus depreciation on the GA return and track a separate state depreciation basis rollforward.
- Pass-Through Entity Tax (PTET) Election: Georgia offers an elective Pass-Through Entity Tax (PTET) at an effective rate of 5.39% for S-Corporations and Partnerships (1065/1120-S) looking to bypass the $10,000 federal SALT deduction cap.
