California does not have a statewide general business license, but most cities and counties require a local business license or business tax certificate. Businesses must register with the California Secretary of State for entity formation, obtain a seller's permit from the California Department of Tax and Fee Administration if selling taxable goods, and register with the EDD for payroll taxes if employing workers. San Francisco, Los Angeles, and other major cities have their own business registration and tax requirements.

6
Get professional liability (E&O) insurance — typically a low-to-mid four-figure annual premium; protects against claims of tax preparation errors
7
Set up an IRS e-Services account and apply for an Electronic Filing Identification Number (EFIN) to e-file returns
8
Build a client intake process with a tax organizer checklist and engagement letter signed before any work begins

Frequently Asked Questions

A tax preparation business can start for a low-to-mid four-figure investment, with the main costs being tax software, PTIN registration, office equipment, and marketing. Home-based operations eliminate office rent entirely.

No — anyone can prepare federal taxes for compensation if they register for a PTIN. However, CPAs, EAs, and attorneys can represent clients before the IRS, charge higher rates, and are subject to continuing education requirements. Oregon and California require state licensing for all paid preparers.

Average fees nationally are a low three-figure dollar charge for individual returns and a meaningful four-figure fee for business returns. Complex individual returns (rental income, self-employment, investments) command a higher three-figure fee. Your market and credential level determine acceptable pricing.

Tax season runs January 15 – April 15 with an extended September 15 deadline for extensions. Most revenue is earned in 3 months. Successful preparers build year-round income from amended returns, IRS notices, bookkeeping, and payroll services.
