    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 Indiana

2 stops

  1. Indiana Business Registration (Secretary of State) and County DBA Recording

    A bookkeeping or accounting business structured as an LLC, corporation, or partnership registers with the Indiana Secretary of State through the INBiz portal. A sole proprietor or general partnership operating under a trade name instead records a Certificate of Assumed Business Name with the County Recorder in the county where the business is located — not with the Secretary of State and not with a county clerk. Recording fees are set locally under IC 36-2-7-10 and differ by county, so check your own county recorder's fee schedule. An LLC is worth considering for liability protection.

    Official government source

    Secretary of State entity filing fees are published on the INBiz portal. County DBA recording fees are local and vary: $35 in Marion County, $25 in Allen County, $25 in Vanderburgh County — there is no statewide flat fee.Online INBiz entity filings are processed by the Secretary of State; no fixed turnaround is published. County recorders typically record an assumed-name certificate at the counter while you wait, or by mail.

  2. Indiana Department of Revenue — Registered Retail Merchant Certificate (Sales Tax)

    Indiana imposes sales tax on tangible personal property, not on professional services, so bookkeeping and accounting fees are not taxable. You need a Registered Retail Merchant Certificate (RRMC) only if you sell tangible goods at retail. You still owe 7% use tax on taxable items purchased without Indiana tax paid. Register through INBiz using the BT-1 business tax application.

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

    Indianapolis does not have a distinct 'Home Occupation Permit.' Home-based bookkeeping businesses must comply with residential zoning use restrictions (no client foot traffic, no exterior signage) but do not file a separate permit for this. If zoning status needs confirming, a Zoning Classification Letter ($85) can be requested from DBNS.
