  2. IRS Preparer Tax Identification Number (PTIN)

    Required for any paid preparer who prepares or assists in preparing federal tax returns for clients.

State of Connecticut

2 stops

  1. Connecticut business registration (Secretary of the State) and trade name filing

    Bookkeeping and accounting businesses formed as an LLC, corporation or partnership must register with the Connecticut Secretary of the State; an LLC's certificate of organization costs $120 and the annual report is $80. Sole proprietors operating under a trade name file a trade name certificate with the town clerk where the business operates (CGS Sec. 35-1) - Connecticut has no county government or county clerks. An LLC also gives personal liability protection that a trade name filing does not.

    Official government source

  2. Connecticut Sales/Use Tax Registration (if applicable)

    Bookkeeping and accounting services are generally not subject to sales tax in Connecticut as a professional service. However, if the business sells tangible goods or CT specifically taxes the service, a Sales and Use Tax Permit ($100 registration fee) may be required. Verify with the Connecticut Department of Revenue Services.

City of New Haven / New Haven County

2 stops

  1. No New Haven general business license (category-specific licenses only)

    New Haven has no blanket general business license and Connecticut has no statewide one. The city's Licenses & Permits index routes 'Business License' to the Permit & License Center, whose licences are strictly category-specific: Amusement, Auction and Auctioneer, Broker (secondhand, antique and precious-metal dealers, pawnbrokers, junk dealers, swap shops), Rooming House, Sales (closing-out sales, door-to-door solicitors, tag sales) and Street Vendor/Peddler. There is no business-tax certificate, occupational licence or gross-receipts fee applied to all businesses. A bookkeeping or accounting service falls in none of those categories, so it needs no city licence. Its obligations are a Secretary of the State filing if it is an LLC, corporation or partnership, a trade name certificate with the New Haven City Clerk if it trades under an assumed name, and zoning compliance if it is home-based.

    No fee - New Haven issues no general business license for this activityNot applicable - no general business license exists to apply for

  2. New Haven zoning compliance for a home-based business

    A bookkeeping business run from a New Haven residence must have its home-based use comply with the city's zoning ordinance, handled through the Office of Building Inspection & Enforcement's zoning permit process rather than by a separately branded home occupation office. Typical Connecticut home-occupation limits are that the business must be clearly incidental to residential use, employ no non-resident staff at the premises, generate no client foot traffic or customer parking, carry no exterior signage and involve no outdoor storage. A computer-based bookkeeping practice with no client visits normally satisfies them. New Haven issues no general business license, so zoning compliance and a trade name certificate with the City Clerk are the substantive local steps.

    Official government source

    Zoning permit and zoning compliance letter fees are set by New Haven's adopted fee schedule; Connecticut sets no statewide home occupation feeZoning compliance is determined administratively; only uses requiring a special exception or variance go before the City Plan Commission or Board of Zoning Appeals on their published calendars
