  1. EIN (Employer Identification Number)

    Required if you have employees or operate as an LLC or corporation. Free from the IRS, obtained instantly online. Sole proprietors without employees may use their SSN, but an EIN is recommended for privacy and professional credibility.

  2. IRS Preparer Tax Identification Number (PTIN)

    Required for any paid preparer who prepares or assists in preparing federal tax returns for clients. If your bookkeeping practice includes any federal tax return preparation, you must obtain and renew your PTIN annually. Bookkeeping-only services (no tax return preparation) do not require a PTIN.

  1. Wisconsin Business Registration

    Bookkeeping and accounting service businesses operating in Wisconsin must register with the Wisconsin Department of Financial Institutions (or equivalent) if structured as an LLC, corporation, or partnership. Sole proprietors operating under a trade name must file a DBA (Doing Business As) registration with the state or county clerk. An LLC is strongly recommended for liability protection.

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

    Bookkeeping and accounting services are generally not subject to sales tax in most states as a professional service. However, if the business sells any tangible goods (e.g., software on physical media, printed reports) or if Wisconsin specifically taxes business services, a seller's permit or sales tax license may be required. Verify with the Wisconsin Department of Revenue.

  1. Milwaukee General Business License

    All businesses operating within Milwaukee must obtain a general business license (also called a business tax certificate or occupational license) from the city. For a bookkeeping or accounting service, this is a straightforward administrative registration. No specialized local certification is required beyond the standard business license. Must be renewed annually.

  2. Milwaukee Home Occupation Permit (if home-based)

    Bookkeeping businesses operated from a residence in Milwaukee typically require a Home Occupation Permit or Home Business Zoning Approval from the city planning department. This confirms the business activity is compatible with residential zoning. Standard restrictions: no client foot traffic, no exterior signage, limited storage of business materials. Online bookkeeping businesses typically qualify easily.
