Frequently Asked Questions

A tax preparation business can start for $5,000–$15,000, with the main costs being tax software ($600–$1,800/year), PTIN registration ($19.95/year), office equipment ($500–$1,500), 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 $220 for individual returns and $800–$1,500 for business returns. Complex individual returns (rental income, self-employment, investments) command $300–$500+. 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.
