How to Start a Tax Preparation Business

Starting a tax preparation business requires a PTIN (Preparer Tax Identification Number) from the IRS for anyone who prepares returns for compensation, and an EFIN (Electronic Filing Identification Number) if you'll e-file on clients' behalf, plus a decision about credential level, tax software, and pricing before your first filing season opens. Unlike bookkeeping, tax preparation touches federal requirements from day one — you can't legally prepare returns for pay without a PTIN, full stop. The good news is that the path from "I want to do this" to "I have my first paying client" is well-defined and doesn't require years of schooling unless you choose a credential that calls for it. The habit that matters just as much as the paperwork is building a plan to get reviews after your first filing season instead of letting that first April pass without asking anyone. Getting your PTIN Every paid tax preparer needs a PTIN, obtained directly from the IRS, renewed annually, and required on every return you sign. It's a straightforward online application with a modest fee, and it's the one requirement that applies to literally every paid preparer regardless of credential level . Do you also need an EFIN? An EFIN is a separate requirement, needed only if you'll be transmitting returns electronically on behalf of clients — which the overwhelming majority of preparers do, since paper filing is now rare. The EFIN application involves a more thorough IRS review than the PTIN, including a suitability check, and takes longer to process, so it's worth starting well before filing season rather than the week you plan to open for business . State registration requirements Federal requirements — PTIN, and EFIN if you're e-filing — apply everywhere, but a handful of states layer their own registration or licensing requirements on top. California requires non-exempt preparers to register with the California Tax Education Council (CTEC), complete specific education hours, and carry a bond. New York requires its own preparer registration separate from the federal PTIN. Oregon requires a state license through its own Board of Tax Practitioners, with its own exam . If you plan to prepare returns for clients in any of these states, check that state's requirements before your first client engagement, not after — operating without a required state registration can mean fines on top of the embarrassment of having to pause mid-season. Most other states have no separate preparer registration requirement at all, relying entirely on the federal PTIN system, but the list of states with their own rules has changed over time as more states consider adding oversight, so it's worth checking your specific state's current requirement directly rather than assuming based on what was true a few years ago. Circular 230: the baseline professional conduct rules IRS Circular 230 sets out the rules of practice before the IRS, and while its most restrictive provisions apply specifically to "practitioners" — Enrolled Agents, CPAs, and attorneys — several of its general standards of conduct (due diligence on the accuracy of positions taken, avoiding conflicts of interest, and rules around fee practices) are treated as baseline professional expectations across the tax preparation industry more broadly . Reading through Circular 230 once before your first season, even as an unenrolled preparer, gives you a working sense of the professional norms the IRS expects, well beyond the narrow question of who it formally governs. Choosing your credential level You don't need a CPA license or a law degree to prepare tax returns for compensation, but your credential level affects what you're allowed to do for a client beyond simple preparation. Unenrolled preparer — the PTIN alone lets you prepare returns, but your ability to represent a client in front of the IRS is limited. Enrolled Agent (EA) — a federal credential earned by passing a three-part IRS exam, giving unlimited rights to represent clients before the IRS on any tax matter. CPA — requires state licensure, significantly more education, and an additional exam, with broader scope beyond tax work alone. Many successful solo tax preparation businesses operate for years as unenrolled preparers before deciding whether the EA credential is worth pursuing . The EA path tends to make the most sense once you want to represent clients through an audit or a dispute with the IRS directly, rather than just prepare the return. Business structure and insurance basics A sole proprietorship or single-member LLC covers most solo tax preparers starting out, with the LLC preferred once real client money and real liability exposure are involved — it keeps a mistake on a client's return from putting your personal assets at risk in a worst-case dispute. Get a federal EIN even if you're a sole proprietor, both to keep your Social Security number off client-facing paperwork and because many professional tax software vendors require one for the business account setup. Errors and omissions (E&O) insurance matters more for tax preparation than for almost any other small professional service, because a preparation mistake can directly cost a client real money — a missed deduction, an incorrectly claimed credit that triggers a penalty, a filing error that delays a refund a client was counting on. A single E&O claim without coverage can be far more expensive than years of premiums, and plenty of referral partners and some software vendors will ask whether you carry it before working with you. Picking tax software Professional tax software is a different product category from the consumer software your clients might use themselves — it's built for volume, has built-in e-file infrastructure tied to your EFIN, and typically costs considerably more than a consumer license. Most new preparers choose based on a combination of price, the complexity of returns they expect to handle, and how well the software supports the specific states they'll be filing in . Pricing your first filing season Most new preparers price too low out of fear of losing their first few clients, then spend their second season catching up. A workable starting approach is to price by return complexity — a simple W-2-only return costs far less time than a return with a Schedule C, rental property, or multiple state filings — rather than a single flat rate for everyone. Looking at what established local preparers charge for comparable complexity gives you a realistic anchor before you set your own rates. It's worth deciding upfront how you'll handle the returns that turn out more complex than they first appeared — a client who mentions a W-2 on the phone but shows up with a side business and three rental properties is common enough that your intake process should flag it before you've quoted a price, not after you've already started the return. A short, specific intake questionnaire before the first appointment, rather than a quick phone call, catches most of this complexity early. Marketing to land your first clients A first filing season usually fills up through personal networks — family, friends, former colleagues — supplemented by simple local visibility: a complete Google Business Profile, a basic website, and word of mouth once your first few clients are satisfied. Referral relationships with bookkeepers who don't prepare taxes themselves, and with financial advisors whose clients need a tax preparer, tend to produce steady inbound work once established. Our broader guide, How to Get More Accounting Clients, covers tactics that apply to tax preparation as much as to accounting generally. A complete, well-categorized Google Business Profile matters more for a first-year tax preparer than almost any other marketing effort, because most individual filers searching for help in January and February are comparing a handful of local options with no prior relationship to any of them. Listing the specific return types you handle — self-employment income, rental property, multiple states — rather than a generic "tax preparation" description helps the right clients self-select into your first season instead of signing up a complexity you didn't price for. Building your review process from the very first season The single best moment to ask a tax client for a review is the week or two after their return is filed and accepted — the stress is over, the outcome is known, and the request feels timely rather than random. Build the habit in from your very first season rather than waiting until you have a larger client base: ask every client the same way, regardless of whether they owed money or got a refund. Selectively asking only the clients who got good news is review gating, which carries real legal exposure in addition to being against most platform terms — see why review gating is a legal risk. Never tie an incentive like a discount on next year's fee to leaving a review; the FTC's rule on fake and deceptive reviews (16 CFR §465) prohibits conditional incentives outright. Bringing every platform — Google, Yelp, Facebook — into a single inbox matters even for a brand-new, one-person practice, since the alternative is checking three sites by hand during the exact weeks of the year you have the least spare time to do it. A tool that automatically sends the request when a return closes and surfaces every new review in one place removes that burden from the busiest stretch of your calendar rather than adding to it. One wrinkle specific to tax preparers: using a client's contact information to send a review request touches the same territory as IRC §7216, which restricts how tax return information and, depending on interpretation, the client relationship itself can be used for purposes beyond preparing the return. Using your own client list to invite your own clients to leave a review is generally treated as permitted marketing to your own existing clients rather than a disclosure of return information, but the specifics depend on your consent language and how the request is worded . Our full breakdown of what consent language covers and what it doesn't is in Section 7216 Consent: What Tax Preparers Can Use for Marketing — worth reading before you send your first automated request. If a review does come in with any complaint about their outcome — a smaller refund or a bigger bill than expected — the safe reply never confirms specific numbers or filing details publicly. Our guide on how CPAs should respond to negative reviews without breaching confidentiality covers the reply mechanics in depth, and the same rules apply whether you're a CPA firm or a standalone tax preparation business. Frequently asked questions Do I need both a PTIN and an EFIN, or just one? You need a PTIN to prepare any return for compensation — no exceptions. You only need an EFIN if you'll be e-filing returns on behalf of clients, which almost every preparer does given how rare paper filing has become in practice. Can I start part-time out of my home? Yes. Many tax preparation businesses start as a part-time, home-based operation during filing season, especially for a preparer still working another job the rest of the year. The PTIN and EFIN requirements apply regardless of whether you're full-time or seasonal. When should I ask a first-season client for a review? Right after their return is filed and accepted — build that trigger into your process from the start rather than treating it as something to figure out once you're established. Ask every client the same way, with no incentive attached. Do I need to register in every state where I have clients? It depends entirely on the state, not on where your business is physically located. A handful of states, including California and New York, have their own preparer registration requirements that apply based on where the client's return is being filed . Check each state where you expect to have clients before your first season, rather than assuming your home state's rules are the only ones that apply. What happens if I make a mistake on a client's return? Mistakes happen even to experienced preparers, and how you handle one matters more than the fact that it occurred. Correcting the error promptly, communicating clearly with the client about what happened and what you're doing about it, and having E&O insurance in place for anything that causes real financial harm all matter far more to how the relationship — and any eventual review — turns out than the mistake itself. A defensive, slow, or evasive response to a caught error does far more reputational damage than the original mistake. Every review from Google, Facebook and Yelp in one inbox → Try Tailwind free.
