How to Start a Tax Preparation Business in Minnesota: No State License but PTIN and Penalties

Minnesota does not license paid tax preparers. There is no state exam, no state certificate and no state renewal fee to pay. That makes the state one of the easier places to start a tax preparation business, but it does not make it a free-for-all. The Minnesota Department of Revenue expects anyone who prepares returns for pay to meet a short list of duties, and the penalties for skipping them are specific, assessed per return or per violation, and in some cases steep.

This guide walks through what to set up, in the order we would do it, along with the mistakes that catch new preparers. It is informational content, not legal or tax advice. Rules change, so confirm any figure that affects your filings with the agency named.

What you need before you start

Gather these items before you file anything. Most cost little or nothing, but the PTIN and the written information security plan are required before you prepare a single paid return.

• A valid, unexpired federal PTIN from the IRS for yourself and for every person who will prepare returns for pay.
• An EIN for the business if you form an LLC or corporation, or if you have employees. Minnesota requires the PTIN or EIN on the returns you prepare, so make sure the right identifier is on file.
• A written information security plan covering how you store, share and dispose of client data.
• A business name you have checked against Secretary of State records.
• A Minnesota street address for your registered office if you form an LLC or corporation. A PO box by itself is not accepted.
• Filing money: $155 for Articles of Organization or Articles of Incorporation filed online or in person, or $135 by mail. Add $50 online or in person, or $30 by mail, if you use an assumed name.
• A publication budget if you file an assumed name. Newspaper rates vary, so get quotes before you file.
• An e-file provider you can use. Losing e-file authority is one of the penalties described below, so choose software you can run within the conduct rules.
• Client intake and engagement forms. If you offer refund anticipation loans, you also need the disclosures covered in Step 3.
• Quotes for professional liability insurance. Ask each insurer whether the policy covers errors in returns you prepare.

Step 1: Confirm which licenses actually apply

Minnesota has no general statewide business license. Filing your entity with the Secretary of State is a filing, not a license. Registering with the Department of Revenue for a Minnesota Tax ID is a tax registration, not a license. Neither one authorizes you to prepare returns.

Licensing in Minnesota is by trade or activity, and individual agencies issue it. If you plan to add a service that falls under another regulated trade, search for it on License Minnesota at mn.gov/elicense and confirm with the agency that handles it before you offer the service. For tax preparation itself, the state's requirements are the PTIN, the security plan and the conduct rules in Step 3.

Step 2: Get your federal PTIN and keep it current

The IRS issues the Preparer Tax Identification Number. Every person who prepares a federal return for pay needs one, and it must be valid and unexpired when you prepare the return. Minnesota adds a state-level rule: you must provide your PTIN on Minnesota returns. Put your renewal date on the calendar as soon as you receive the number.

A lapsed or missing PTIN is not a paperwork issue you can fix later. Under Minnesota law, a preparer who had no PTIN when one was required can be assessed up to $500 per return. If you hire seasonal help, each preparer needs a PTIN of their own, and each one signs with it. Do not let a worker prepare returns without one.

Step 3: Write the security plan and learn the standards of conduct

Minnesota requires paid preparers to keep a written information security plan. Write it before your first client sits down. A short plan you actually follow beats a long one you never open. It should name who can access client files, where those files live (a locked cabinet, an encrypted cloud account or both), how you exchange documents with clients, and how you destroy paper and electronic records when the retention period ends. Ask your CPA to review it once.

Next, read the standards of conduct in Minn. Stat. 270C.4451. They govern what you may and may not do when preparing and signing returns and how you deal with clients. Turn them into a short checklist and use it on every return.

Two more duties apply. If you offer refund anticipation loans, you must make the required refund anticipation loan disclosures to clients. You must also file your own returns on time. A preparer with late personal or business filings has a hard time explaining why clients should trust theirs.

Step 4: Choose a legal structure and form it

Many tax preparers start as sole proprietors. A sole proprietorship needs no state formation filing unless you operate under a name other than your own, and that case is covered in Step 5. Many preparers later move to an LLC to separate personal and business liability as revenue and client files grow. Your choice affects both taxes and paperwork, so discuss it with a qualified CPA or attorney before you file.

To form an LLC, file Articles of Organization under Minnesota Statutes Chapter 322C through Business Filings Online at mblsportal.sos.mn.gov/Business/Search. The fee is $155 if you file online or in person, which is expedited service, or $135 by mail, which is not expedited. The name must contain “limited liability company” or “LLC,” and it cannot be confused with any Minnesota entity already on the Secretary of State records. You must have a registered office at a Minnesota street address. A registered agent is optional for a Minnesota LLC. Formation does not require newspaper publication.

Tax treatment is a separate question. Minnesota has no separate LLC franchise tax. An LLC taxed as a partnership or disregarded entity passes income to its owners, who pay the individual income tax at 5.35 to 9.85 percent. An LLC that files federally as a C corporation pays the 9.8 percent corporation franchise tax. A minimum fee under Minn. Stat. 290.0922 applies to C corporations, S corporations and partnerships, but single-member LLCs that report only on the owner's individual return are exempt. For 2026, that minimum fee is $0 below $1,280,000 of Minnesota property, payroll and sales, rising in brackets to $12,830 at $51,280,000 and above.

A corporation files Articles of Incorporation under Minnesota Statutes Chapter 302A at the same $155 online or in person rate, and it carries the same annual renewal duty as an LLC.

Annual renewal for an LLC or corporation is due every December 31. The renewal fee is $0 if the entity is active and in good standing. Miss the deadline and an LLC is terminated or revoked without further notice, so mark the first week of December on your calendar. If you do fall behind, the current Secretary of State schedule lists reinstatement at $65 by mail or $85 online or in person for an LLC. Confirm that figure on the Secretary of State site before you pay, because published fee schedules change.

Step 5: File an assumed name if you will not use your own name

If your firm operates under a name other than the legal name of the owner or entity, file a Certificate of Assumed Name with the Minnesota Secretary of State, Business Services. It costs $50 online or in person, or $30 by mail. Filing is only half the job. You must publish the certificate for two consecutive issues in the legal notices section of a qualified legal newspaper in the county where your principal place of business is located. Failure to publish may render the certificate invalid, so do not skip it. Renew the assumed name each year at no charge. Start at sos.mn.gov/business-liens/business-forms-fees/assumed-namedba/.

Publication is the step new filers forget. Call two or three qualified newspapers in your county, compare the quotes and schedule the publication dates before you need the certificate for a bank account or a client contract.

Step 6: Register with the Department of Revenue

Register with the Minnesota Department of Revenue to obtain a Minnesota Tax ID. This is a tax registration, not a license, but you must complete it before making taxable sales. It is also how you open a sales and use tax account if any of your products or services are taxable. Whether your tax preparation services carry sales tax is a question to confirm with Revenue, not something to assume. The state sales tax rate is 6.875 percent, and local taxes can be added on top. Start the registration at the Revenue new business registration page. If you hire employees, ask Revenue about withholding registration before your first payroll.

Step 7: Check city, county and township rules for your location

Minnesota has 87 counties, about 853 cities and about 1,780 townships. Local governments control zoning and any local licensing, and the rules differ from place to place. Minneapolis and Saint Paul both license businesses by category, and neither issues a general business license. Confirm whether your activity falls in a licensed category before you open. If you plan to work from home, check your city's home occupation rules before you schedule client appointments at your residence.

Step 8: Build penalty controls into every return

This is the step most new preparers underestimate. Minnesota penalties attach to each return or each violation, so one careless habit repeated across a season adds up quickly. Build your intake and review process around this schedule:

Violation	Penalty	Reference
Leaving the PTIN or EIN off a Minnesota individual, refund claim, property tax refund, corporation franchise or fiduciary return	$50 per return	Department of Revenue
Failing to provide a PTIN when one was required	Up to $500 per return	Minn. Stat. 289A.60 subd. 28
Reckless disregard of the law, or willful understatement of tax	$500	Minn. Stat. 289A.60 subd. 13
Violating the standards of conduct	Up to $1,000 per violation, with possible loss of e-file authority	Minn. Stat. 270C.4451
Violating a cease and desist order	Penalties up to $5,000 per violation	Minn. Stat. 270C.445

Use these numbers as a floor, not a ceiling. At $50 per return, forty returns with the identifier missing is $2,000 before any other penalty applies. Your review checklist should confirm the PTIN and EIN on every return, the signed conduct checklist, the refund anticipation loan disclosure where it applies, and the file location under your security plan. Keep your records for as long as the retention period in your plan requires, and confirm that period with your CPA.

Step 9: Prepare for your first season

Before the season opens, test your e-file software with your PTIN loaded in its profile, run a few sample returns through your checklist and confirm that your security plan matches what you actually do. Schedule your own December 31 entity renewal and your own filing deadlines in the same calendar. Then start taking clients.

Common mistakes to avoid

• Assuming “no state license” means “no rules.” The PTIN, the security plan, the standards of conduct and the penalties all apply.
• Treating the Secretary of State filing or the Revenue registration as a license. Neither one authorizes tax preparation by itself.
• Letting a seasonal hire prepare returns without a PTIN of their own.
• Listing a PO box as the registered office for an LLC.
• Skipping newspaper publication on an assumed name, which may make the certificate invalid.
• Missing the December 31 renewal, which can end an LLC's standing.
• Offering refund anticipation loans without the required disclosures.
• Assuming your services are exempt from sales tax without confirming with Revenue.
• Filing your own business or personal returns late.

Tips that save time and money

• Compare the $20 difference between online and mail filing against your timeline. Online and in-person filings are expedited, and mail filings are not.
• Search the Secretary of State business records before you pick a name, so you do not lose the filing fee to a conflict.
• Have a CPA review your entity choice and security plan once, then revisit them when your revenue or client base changes.
• Ask the Minnesota Small Business Development Center Network, administered by the Department of Employment and Economic Development, for business advising before you commit to a lease or a long contract.
• Keep a single folder with your PTIN, EIN, filing receipts, publication affidavits and Revenue registration. Audits and renewals go faster when the records are in one place.

What results to expect

A careful start can produce a business that operates within the rules, files cleanly and grows without expensive rework. For many new preparers, the largest early cost may be the time spent on the security plan, the checklist and the recordkeeping rather than the state filing fees. Results depend on your location, your client mix, your software and how consistently you follow the rules, so treat any outcome as a possibility rather than a promise. Preparers who keep clean records may be better positioned to earn repeat clients, but no outcome is guaranteed.
