How to Start a Tax Preparation Business in 2026

The IRS lets almost anyone prepare a tax return for pay. Almost. You do not need a CPA license or a degree to hang a tax-prep shingle — you need a couple of IRS registrations and a decision about how far up the credential ladder you want to climb. That accessibility is why tax prep is one of the more reachable professional-services businesses to start, and it is also why the ones that last are built on more than the minimum: a real credential, a data-security plan the IRS actually requires, and a client base that comes back every year.

Because returns are seasonal, the business has a distinct rhythm — a compressed, brutal filing season and a quieter rest of the year that the smart preparers fill with extensions, planning, and year-round bookkeeping clients. This guide walks the model choice, the PTIN and EFIN and the credential path, state requirements, the data-security obligation new preparers miss, honest startup costs, finding clients, the mistakes that cause trouble, and where software fits around your tax software.

Decide what returns you prepare and how credentialed you want to be. At the base, an unenrolled preparer with the required IRS registration can prepare returns for compensation. One rung up, the IRS Annual Filing Season Program (AFSP) is a voluntary continuing-education path that gives unenrolled preparers a record of completion and limited representation rights before the IRS. Higher still, an Enrolled Agent (EA) — earned by passing the IRS Special Enrollment Examination or through qualifying IRS experience — is a federal credential with unlimited representation rights, and a CPA is a state-licensed credential that also covers audit and broader accounting.

Your credential shapes what you can offer and charge. Simple individual 1040 returns are the entry point; small-business returns, multistate filings, and representing clients before the IRS command more and require more expertise. You also choose independent versus franchise: an independent practice keeps all the margin and builds your own brand, while a tax franchise provides a name, training, and systems in exchange for fees and less control. Many preparers start unenrolled or with AFSP doing individual returns, then pursue the EA to move upmarket and serve businesses.

Two IRS registrations are the non-negotiable foundation. A PTIN — Preparer Tax Identification Number — is required by the IRS for anyone who prepares federal tax returns for compensation; you renew it annually and it is straightforward to obtain. An EFIN — Electronic Filing Identification Number — is what lets you e-file returns as an Authorized IRS e-file Provider; it is free but the application is more involved, including a suitability check that can involve fingerprinting and a background review, so apply well before filing season because processing takes time. Nearly every paid preparer needs both.

On top of the federal registrations, some states impose their own requirements. A number of states — California and Oregon are frequently cited, among others like Maryland, New York, and Connecticut — register or license tax preparers, and some require a bond or state-specific education. These vary significantly, so check both the IRS requirements and your state's rules directly rather than assuming the federal registrations are enough. Getting the PTIN and EFIN in place, and confirming any state registration, is the licensing work that lets you legally and electronically file returns for clients.

Here is the obligation new preparers most often miss: the IRS requires paid tax preparers to have a written information security plan to protect client data, under the FTC Safeguards Rule. This is not optional and it is not just paperwork — you handle Social Security numbers, income, and bank details for every client, and you are required to have a documented plan for safeguarding that data. Build it as part of setup, not as an afterthought, and make sure every tool you use to collect or store client documents fits within it.

Startup costs are moderate and dominated by software. Professional tax-preparation software is the main expense, priced per return or as an unlimited package, and it is what actually prepares and transmits returns. Add the PTIN fee, errors-and-omissions insurance, a secure way to exchange documents with clients, a computer, and continuing education. Because the business is seasonal, cash is lumpy — heavy in filing season, thin afterward — so preparers smooth it by adding extensions, tax planning, and year-round bookkeeping clients. The capital required is low enough that many preparers start from a home office, which makes the data-security plan and secure document handling even more important.

Tax clients are sticky and seasonal. A client who trusts you with this year's return usually comes back next year and the year after, so the lifetime value of a first client is high and the game is acquisition plus retention. Your first clients typically come from your existing network, referrals, and your local community — friends, family, small-business owners you know, and the people they refer once they have a good experience. A specific niche accelerates it: the preparer known for gig workers and independent contractors, or for a particular small-business type, or for expats and complex situations, gets referred within that community far faster than a generalist.

Timing matters in this business more than most. The weeks before and during filing season are when demand spikes and when your marketing has to be visible, and appointment scheduling becomes the operational bottleneck — a preparer who can smoothly book, remind, and manage a crush of season appointments serves more clients without chaos. Year-round, the retention play is to convert seasonal filers into planning and bookkeeping relationships, which both smooths your revenue and deepens the client tie. Reliability, accuracy, and clear communication turn a one-time filer into a decade-long client.

Your professional tax software is what prepares and e-files returns, and Deelo is not that — it does not calculate or transmit returns and is not IRS-authorized filing software. What Deelo runs at $19/seat/month is the client relationship, scheduling, intake, and billing that surround the return, which is exactly where a seasonal practice gets overwhelmed. Whatever you use to collect and store client documents must fit within your written data-security plan, so confirm your handling meets that obligation.

Deelo CRM tracks every client and the status of their return — waiting on documents, in progress, filed — with custom fields for return type, niche, and referral source, so nothing gets lost in the season crush. Bookings runs the appointment scheduling that makes or breaks filing season, with reminders that cut no-shows when every slot counts. Invoicing bills prep fees and supports recurring invoices for year-round bookkeeping and planning clients that smooth your off-season. Forms handles client intake questionnaires and organizers, ESign covers engagement letters, and the AI assistant drafts client reminders and follow-ups. Keep your tax software for the returns; let Deelo run the practice around it.
