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.

  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 Hartford / Hartford County

2 stops

  1. No Hartford general business license (category-specific licensing only)

    Hartford does not issue one blanket general business license to all businesses, and Connecticut has no statewide business-tax certificate or occupational licence. Licensing is category-specific and administered by the Licenses & Inspections division of the Department of Development Services through the city's Accela permitting portal, covering regulated activities such as food establishments, vendors, laundromats, amusement devices and parking lots. A bookkeeping or accounting service is not a licensed category. Its actual obligations are a Secretary of the State filing if organised as an LLC, corporation or partnership, a trade name certificate with the Town & City Clerk if trading under an assumed name, and zoning compliance for the premises.

  2. Hartford zoning compliance for a home-based business

    A bookkeeping practice run from a Hartford residence must comply with the City of Hartford Zoning Regulations for home-based occupations, administered by the Department of Development Services rather than by a separately branded 'home occupation permit' office. Zoning review, permits and compliance letters are handled through the city's Accela permitting portal and the Licenses & Inspections division. Typical Connecticut home-occupation limits are no non-resident employees working on site, no client foot traffic, no exterior signage and no outdoor storage - conditions a computer-based bookkeeping practice with no client visits normally meets. Hartford issues no general business license for bookkeeping services.

    Official government source

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