    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.

State of Missouri

  1. Missouri Business Registration

    Bookkeeping and accounting service businesses operating in Missouri must register with the Missouri Secretary of State (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 Missouri Secretary of State (fictitious name registration, RSMo Chapter 417). An LLC is strongly recommended for liability protection.

  2. Missouri 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 Missouri specifically taxes business services, a seller's permit or sales tax license may be required. Verify with the Missouri Department of Revenue.
