Do early-stage C-Corps need a CPA?+

What is QSBS and why does it matter?+
Qualified Small Business Stock (QSBS) can let founders and early investors exclude a significant portion of capital gains from tax on a future sale, if specific requirements are met from the start. A C-Corp accountant tracks eligibility from formation, since it can't be fixed retroactively.
