For 2027, Atlanta startups should track federal corporate taxes, Georgia income and net worth taxes, and the City of Atlanta’s Occupational Tax Certificate requirements as separate workstreams. The City of Atlanta currently requires renewal applications by February 15 and payment by April 1. Georgia’s annual registration with the Secretary of State is also due April 1. Property returns and tax bills depend on the business’s location and assets, so founders should identify the appropriate county, such as Fulton County or DeKalb County, rather than assume every Atlanta address falls under Fulton County.
Add these dates to the federal deadlines on Kruze’s tax compliance calendar to keep every jurisdiction in one place.
