How to start a tax preparation business.
The requirements, in order, with the dates that matter. Most of it you can finish in a few weeks. The exception is the EFIN, which can take up to 45 days, so start there.
Work backward from the first week of the season.
- Now
Set up and apply
Business setup, PTIN, and your EFIN application. The EFIN is the long pole.
- By mid-November
EFIN in hand
Apply at least 45 days before you want to file. Write your security plan while you wait.
- Nov – Dec
Get ready
Bank-product enrollment (needs an active EFIN), insurance, and software and due-diligence training.
- January
Open the doors
Marketing live early in the month, so clients find you before the first refunds go out.
Ten steps to a working tax office.
Every office needs steps 1 through 8. Steps 9 and 10 are what separate a strong first season from a slow one.
Set up the business
Choose your business structure, get a free EIN from the IRS, open a business bank account, and get any local business license your city or county requires.
Get your PTIN
Every paid preparer needs a Preparer Tax Identification Number from the IRS, renewed each year. The IRS sets the PTIN fee each year; it was $18.75 for 2026.
Apply for your own EFIN
Your Electronic Filing Identification Number lets your office e-file. Apply online with the IRS e-file application in e-Services and pass a suitability check. Applicants who are not attorneys, CPAs or enrolled agents are fingerprinted. There is currently no fee, and the IRS says approval can take up to 45 days from the date you submit.
Write your security plan (WISP)
The FTC Safeguards Rule requires tax preparers to have a written information security plan. IRS Publication 5708 gives you a template to start from.
Check your state’s preparer rules
Florida does not regulate tax preparers. Several states do: California (CTEC: 60 hours of education and a $5,000 bond), Oregon (a license), New York (yearly registration), Maryland (registration and an exam) and Connecticut (a permit above 10 returns). Check your state before the season.
Get errors and omissions insurance
E&O coverage protects your office if a mistake on a return costs a client money. Price it before the season, not during.
Enroll in bank products
Bank products let clients pay your fees from their refund instead of out of pocket. Enrollment needs an active EFIN, and we help you through it.
Train on the software and the rules
TaxWise training, plus the rules that carry penalties: due diligence on refundable credits (Form 8867, $665 per failure for returns filed in 2027), e-signature authorization (Form 8879), and client consent before you use or share tax information (IRC §7216).
Consider the Annual Filing Season Program
The IRS’s voluntary AFSP credential shows clients you keep your training current. It takes 18 hours of continuing education (a 6-hour refresher course, 10 hours of federal tax law and 2 hours of ethics), completed by December 31.
Get your marketing live by early January
A Google Business Profile, a simple website and word of mouth in your community. Clients shop early, so be findable before they start looking.
People still want a person to do their taxes.
