About each permit
Sales and Use Tax Permit
Connecticut is unusual twice over. Most states charge nothing for a sales tax permit; this one charges $100 up front. And most states issue a permit that simply never expires; this one expires every two years — but the renewal itself costs nothing and happens automatically, mailed out as long as the account remains active and in good standing. So the $100 is a true one-time cost despite the permit's own two-year clock.
