What liability protections does a limited liability partnership offer Minnesota professionals? An LLP shields you from personal liability for partnership obligations while preserving the pass-through tax treatment and management flexibility of a general partnership. Minnesota governs LLPs under Minn. Stat. ch. 323A, which “may be cited as the ‘Uniform Partnership Act (1994)’” (Minn. Stat. § 323A.1201), and a partnership becomes an LLP by filing a Statement of Qualification with the Secretary of State (Minn. Stat. § 323A.1001). For a broader view of entity selection, see Business Formation in Minnesota.
Why Do Minnesota Professionals Choose LLPs Over Other Entity Types?
LLPs exist primarily to solve one problem: protecting you from personal liability for a co-owner’s mistakes. In a general partnership, “all partners are liable jointly and severally for all obligations of the partnership unless otherwise agreed by the claimant or provided by law” (Minn. Stat. § 323A.0306(a)). In plain terms: if one partner causes a malpractice claim, every partner’s personal assets are exposed.
An LLP displaces that default. Under § 323A.0306(c), “[a]n obligation of a partnership incurred while the partnership is a limited liability partnership, whether arising in contract, tort, or otherwise, is solely the obligation of the partnership,” and a partner “is not personally liable, directly or indirectly, by way of contribution or otherwise, for such an obligation solely by reason of being or so acting as a partner.” Minnesota’s shield is a full shield: it reaches contract and tort obligations alike, not just malpractice claims.
Read the word “solely” carefully, because it marks the edge of the protection. The shield defeats liability imposed on you merely because of your status as a partner, which is exactly what a co-partner’s negligence would otherwise produce. It does not answer a claim that rests on an independent ground, such as your own conduct. The statute contains no express carve-out either way; a partner who himself commits the tort is simply not being held liable “solely by reason of being . . . a partner,” and ordinary tort principles still apply to him. An LLP protects you from what your partners do. It is not a personal-liability eraser.
Two related rules sit in the same section and are worth knowing before you sign anything. First, joining an existing firm does not saddle you with its history: “[a] person admitted as a partner into an existing partnership is not personally liable for any partnership obligation incurred before the person’s admission as a partner” (Minn. Stat. § 323A.0306(b)). That protection applies even in an ordinary general partnership. Second, the shield reaches only obligations “incurred while the partnership is a limited liability partnership,” and the statute fixes when that is: partnership debts under a note, contract, or other agreement “are incurred when the note, contract, or other agreement is entered into,” and “[a]n amendment, modification, extension, or renewal . . . does not affect the time at which” the obligation is incurred (Minn. Stat. § 323A.0306(d)). If you are converting an existing general partnership to LLP status, electing LLP status does not retroactively shield you on contracts you have already signed, and re-papering an old note will not pull it under the shield.
This structure is particularly common among law firms, accounting practices, medical groups, and engineering firms in Minnesota. These professions carry significant malpractice exposure, and the LLP form lets you collaborate without assuming unlimited personal risk for a colleague’s work. An LLC gives comparable protection from the firm’s own debts while differing in governance mechanics, and both forms are available to you. Minn. Stat. § 319B.02, subd. 10 defines a “Minnesota firm” to include “a corporation organized under chapter 302A or 317A, limited liability company organized under chapter 322C, and limited liability partnership that has an effective statement of qualification under section 323A.1001,” and Minn. Stat. § 319B.06, subd. 3(c) leaves owner liability for firm debts to “the firm’s generally applicable governing law.” No Minnesota licensing board may “directly or indirectly require a person providing professional services through a professional firm to assume greater liability for the firm’s debts and obligations than is contemplated by section 319B.06, subdivision 3,” except as a term or requirement of board disciplinary or corrective action (Minn. Stat. § 319B.11, subd. 2). Note also that the Professional Firms Act “do[es] not alter any law applicable to the relationship between a person furnishing professional services and a person receiving the professional services, including liability arising out of the professional services” (Minn. Stat. § 319B.06, subd. 3(a)).
The real reason professionals land on the LLP is structural: an existing general partnership can add a liability shield by filing a statement of qualification, without converting into a different entity type. The partnership itself pays no federal entity-level income tax, because “[a] partnership as such shall not be subject to the income tax imposed by this chapter” (26 U.S.C. § 701), and it keeps partnership governance, where “[e]ach partner has equal rights in the management and conduct of the partnership business” by default (Minn. Stat. § 323A.0401(f)).
The form is not limited to professionals at all: “[a] partnership may become a limited liability partnership pursuant to this section” (Minn. Stat. § 323A.1001(a)), and “[b]usiness” under the chapter “includes every trade, occupation, and profession” (Minn. Stat. § 323A.0101(1)). If you are wondering whether your licensed practice is covered by the Professional Firms Act, the list is long: medicine and surgery, physician assistants, chiropractic, registered nursing, optometry, psychology, social work, marriage and family therapy, professional counseling, dentistry and dental hygiene, pharmacy, podiatric medicine, veterinary medicine, architecture, engineering, surveying, landscape architecture, geoscience, certified interior design, accountancy, and law (Minn. Stat. § 319B.02, subd. 19).
How Does a Minnesota Partnership Register as an LLP?
Converting an existing general partnership to LLP status, or forming a new LLP, requires filing a Statement of Qualification with the Minnesota Secretary of State under Minn. Stat. § 323A.1001; statements under the chapter are filed “in the office of the secretary of state” (Minn. Stat. § 323A.0105(a)). The filing fee is $135 by mail or $155 in person or online.
Start with the vote, not the form. The election is not a unilateral filing: the terms and conditions on which a partnership becomes an LLP “must be approved by the vote necessary to amend the partnership agreement except, in the case of a partnership agreement that expressly considers obligations to contribute to the partnership, the vote necessary to amend those provisions” (Minn. Stat. § 323A.1001(b)). A partner who files without that approval has skipped a statutory condition.
The Statement of Qualification must include the partnership’s name, the street address of its chief executive office (and of a Minnesota office, if different), and, if the partnership has no Minnesota office, the name and street address of an agent for service of process. The partnership must also include “a statement that the partnership elects to be a limited liability partnership” (Minn. Stat. § 323A.1001(c)(4)), plus a deferred effective date if it wants one. If you name an agent, the agent “must be an individual who is a resident of this state or other person authorized to do business in this state” (Minn. Stat. § 323A.1001(d)).
Naming the LLP is a two-part test, and most people know only half of it. The name must include one of six designators: “Registered Limited Liability Partnership,” “Limited Liability Partnership,” “R.L.L.P.,” “L.L.P.,” “RLLP,” or “LLP.” Any one of them suffices, and the punctuated forms are permitted, not required. The name must also meet the general business-name standard of Minn. Stat. § 302A.115, with those LLP designators substituted for the corporate ones. That standard requires that the name be in the English language or in any other language expressed in English letters or characters, that it not contain a word or phrase that indicates or implies that it is incorporated for a purpose other than a legal business purpose, and that it be distinguishable upon the records in the Office of the Secretary of State (Minn. Stat. § 302A.115, subd. 1). See Minn. Stat. § 323A.1002.
If you furnish licensed professional services, you do not get the Minnesota Professional Firms Act by default. Only a firm “that has in effect an election under subdivision 2” may furnish professional services under the Act (Minn. Stat. § 319B.03, subd. 1(a)), and the election is made in the firm’s “organizational document,” which for an LLP is its statement of qualification (Minn. Stat. § 319B.02, subd. 12). So a professional LLP’s statement of qualification must, beyond the baseline content above, state that the firm elects to operate under §§ 319B.01 to 319B.12, acknowledge that it is subject to those sections, and specify the category or categories of professional services it is authorized to provide (Minn. Stat. § 319B.03, subd. 2). You may make the election in the initial filing or add it later, and you may rescind it or change the categories by updating the same document (Minn. Stat. § 319B.03, subd. 3). A professional firm’s name carries its own requirement: a professional LLP’s name must end in “Professional Limited Liability Partnership,” “Limited Liability Partnership,” “P.L.L.P.,” or “L.L.P.,” and “[a] permitted abbreviation may include or omit periods” (Minn. Stat. § 319B.05, subd. 2).
LLP status “is effective on the later of the filing of the statement or a date specified in the statement,” and it “remains effective, regardless of changes in the partnership, until it is canceled pursuant to section 323A.0105(d) or revoked pursuant to section 323A.1003” (Minn. Stat. § 323A.1001(e)). Do not lose sleep over a typo. “The status of a partnership as a limited liability partnership and the liability of its partners is not affected by errors or later changes in the information required to be contained in the statement of qualification under subsection (c)” (Minn. Stat. § 323A.1001(f)), and the filing itself “establishes that a partnership has satisfied all conditions precedent to the qualification of the partnership as a limited liability partnership” (Minn. Stat. § 323A.1001(g)).
What Happens if a Minnesota LLP Misses Its Annual Renewal?
Every Minnesota LLP, and every foreign LLP authorized to transact business here, must file an annual renewal with the Secretary of State “once each calendar year beginning in the year following the calendar year in which a partnership files a statement of qualification or a foreign partnership becomes authorized to transact business in this state” (Minn. Stat. § 323A.1003(b)-(c)). The renewal costs $135 by mail or $155 in person or online, the same as the initial filing. That recurring charge is where the LLP diverges from its neighbors: the Secretary of State’s fee schedule lists the annual renewal for a domestic LLC and a domestic business corporation at $0, so unlike an LLC or a corporation, an LLP pays its full formation fee again every year. See Minnesota Secretary of State, Business Filing & Certification Fee Schedule.
The deadline is December 31, and the Secretary of State’s reminder is discretionary. The statute says the Secretary “may send” a notice, which “will announce the need to file the annual renewal and will inform the partnership or foreign partnership that the annual renewal may be filed online and that paper filings may also be made and that failure to file the notice by December 31 will result in the revocation of the statement of qualification of this limited liability partnership” (Minn. Stat. § 323A.1003(a)). Calendar the date yourself. You cannot rely on the mail.
Miss it, and what gets revoked is your LLP status, not your business name. The Secretary of State “must revoke the statement of qualification of a partnership that fails to file an annual renewal when due or pay the required filing fee” (Minn. Stat. § 323A.1003(d)). Revocation is mandatory, not discretionary, and it is memorialized by a certificate of revocation filed with the Secretary of State. It does not, however, kill the business: “[a] revocation under subsection (d) only affects a partnership’s status as a limited liability partnership and is not an event of dissolution of the partnership” (Minn. Stat. § 323A.1003(e)). The partnership continues as a general partnership. What drops away is the shield.
That is a real exposure while it lasts. The shield in Minn. Stat. § 323A.0306(c) reaches only an obligation “incurred while the partnership is a limited liability partnership,” so during a lapse the default rule governs again: “all partners are liable jointly and severally for all obligations of the partnership” (Minn. Stat. § 323A.0306(a)). Which obligations fall inside the gap turns on the timing rule: a contract debt is incurred when the contract is entered into (Minn. Stat. § 323A.0306(d)).
The cure is a reinstatement, and the statute makes it retroactive. A partnership whose statement of qualification has been revoked “may apply to the secretary of state for reinstatement,” and it “must file an annual renewal to apply for reinstatement and pay a reinstatement fee of $160” (Minn. Stat. § 323A.1003(f)). That $160 is fixed by the statute itself; the Secretary of State’s fee schedule lists the LLP annual reinstatement at $160 by mail and $180 in person or online (Minnesota Secretary of State, Business Filing & Certification Fee Schedule). A reinstatement “relates back to and takes effect as of the effective date of the revocation, and the partnership’s status as a limited liability partnership continues as if the revocation had never occurred” (Minn. Stat. § 323A.1003(g)). How far that relation-back reaches is an open question. The statute contains no express carve-out for obligations incurred during the lapse and no express savings clause for creditors who dealt with the partnership while it was revoked, and we are aware of no published Minnesota appellate decision addressing whether reinstatement extinguishes partner liability that had already accrued on a gap-period obligation. Treat the point as unsettled, and do not plan around it: the safe course is not to lapse at all.
I advise every LLP client to calendar the renewal deadline well before December and to designate a specific partner or administrator responsible for the filing. A $135 renewal is trivial compared to the exposure that opens up in an accidental lapse.
What Fiduciary Duties Do LLP Partners Owe Each Other?
LLP status changes liability to outsiders but does not change the duties partners owe one another. Minnesota makes the list closed: “The only fiduciary duties a partner owes to the partnership and the other partners are the duty of loyalty and the duty of care set forth in subsections (b) and (c)” (Minn. Stat. § 323A.0404(a)). There is no open-ended fiduciary catchall to import.
The duty of loyalty “is limited to” three components. You must “account to the partnership and hold as trustee for it any property, profit, or benefit derived by the partner in the conduct and winding up of the partnership business or derived from a use by the partner of partnership property, including the appropriation of a partnership opportunity” (Minn. Stat. § 323A.0404(b)(1)). You must “refrain from dealing with the partnership in the conduct or winding up of the partnership business as or on behalf of a party having an interest adverse to the partnership” (Minn. Stat. § 323A.0404(b)(2)). And you must “refrain from competing with the partnership in the conduct of the partnership business before the dissolution of the partnership” (Minn. Stat. § 323A.0404(b)(3)).
The duty of care is narrower than ordinary negligence. It “is limited to refraining from engaging in grossly negligent or reckless conduct, intentional misconduct, or a knowing violation of law” (Minn. Stat. § 323A.0404(c)). Ordinary carelessness, or an honest error in business judgment, does not breach it.
Three qualifiers in the same section prevent partners from over-reading those duties, and they are the ones that actually settle arguments. A partner must discharge the duties and exercise any rights “consistently with the obligation of good faith and fair dealing” (Minn. Stat. § 323A.0404(d)), which is an overlay obligation rather than a third fiduciary duty. But “[a] partner does not violate a duty or obligation under this chapter or under the partnership agreement merely because the partner’s conduct furthers the partner’s own interest” (Minn. Stat. § 323A.0404(e)). And a partner “may lend money to and transact other business with the partnership,” with the partner’s rights and obligations on that loan or transaction “the same as those of a person who is not a partner” (Minn. Stat. § 323A.0404(f)). The same standards follow a person who winds up the business as the representative of the last surviving partner (Minn. Stat. § 323A.0404(g)).
A well-drafted partnership agreement is the primary tool for managing all of this, because relations among the partners are governed first by the agreement (Minn. Stat. § 323A.0103(a)). The statutory defaults are unforgiving if you leave them in place. Partners share profits equally and bear losses in proportion to their profit share (Minn. Stat. § 323A.0401(b)). Each partner has equal management rights, regardless of capital contributed (Minn. Stat. § 323A.0401(f)). “A partner is not entitled to remuneration for services performed for the partnership,” except reasonable compensation for winding up (Minn. Stat. § 323A.0401(h)), so the partner who does all the work draws no salary unless the agreement says otherwise. A person “may become a partner only with the consent of all of the partners” (Minn. Stat. § 323A.0401(i)). And ordinary-course disagreements are decided by a majority, while “[a]n act outside the ordinary course of business of a partnership and an amendment to the partnership agreement may be undertaken only with the consent of all of the partners” (Minn. Stat. § 323A.0401(j)).
For professional LLPs, the partnership agreement should also address client-matter allocation, billing structure, and what happens when a partner leaves the firm, including the valuation method for buying out a departing partner’s interest. These provisions prevent the disputes that most commonly threaten professional partnerships.
How Are Minnesota LLPs Taxed?
Minnesota LLPs are flow-through entities for federal and state tax purposes. Income, gains, losses, deductions, and credits pass through to the partners, who report them on their individual returns. Federally, “[a] partnership as such shall not be subject to the income tax imposed by this chapter,” and “[p]ersons carrying on business as partners shall be liable for income tax only in their separate or individual capacities” (26 U.S.C. § 701). Minnesota states the same rule (Minn. Stat. § 290.31, subd. 1).
The mechanics are statutory. The partnership files an information return, Form 1065, stating “specifically the items of its gross income and the deductions allowable” (26 U.S.C. § 6031(a)), and it must furnish each partner, on or before the day that return is due, a copy of that partner’s share of the reported items (26 U.S.C. § 6031(b)). That is the Schedule K-1.
Pass-through treatment avoids the double taxation that hits C corporations, and the point can be put in numbers. A corporation’s income is taxed at the entity level at “21 percent of taxable income” (26 U.S.C. § 11(a)-(b)), and taxed again at the shareholder level, because “[t]hat portion of the distribution which is a dividend . . . shall be included in gross income” (26 U.S.C. § 301(c)(1)). A corporation that elects S status is itself taxed on a pass-through basis, so the double tax is a C corporation problem specifically.
Two Minnesota qualifications keep “the LLP itself pays no tax” from being the whole story. First, the same subdivision that states the pass-through rule expressly makes the partnership “subject to the tax imposed under section 290.0922” (Minn. Stat. § 290.31, subd. 1), the Minnesota minimum fee, a graduated entity-level fee tied to Minnesota property, payroll, and sales and inapplicable to a partnership deriving over 80 percent of its income from farming (Minn. Stat. § 290.0922, subd. 1). Second, for taxable years beginning after December 31, 2020, “a qualifying entity may elect to file a return and pay the pass-through entity tax,” and on that election “a pass-through entity tax is imposed on a qualifying entity in an amount equal to the sum of the tax liability of each qualifying owner” (Minn. Stat. § 289A.08, subd. 7a(b)-(c)). A partnership that “has at least one qualifying owner” is a qualifying entity, and “[q]ualifying entity does not include a publicly traded partnership” (Minn. Stat. § 289A.08, subd. 7a(a)(2)).
That election deserves a line in your partnership agreement, for three reasons drawn from the same subdivision. The tax is computed at “the highest tax rate for individuals under section 290.06, subdivision 2c,” not each partner’s own marginal rate, and “nonbusiness deductions, standard deductions, or personal exemptions are not allowed” (Minn. Stat. § 289A.08, subd. 7a(d)). The election “may only be made by qualifying owners who collectively hold more than 50 percent of the ownership interests in the qualifying entity held by qualifying owners,” “is binding on all qualifying owners who have an ownership interest in the qualifying entity,” and “once made is irrevocable for the taxable year” (Minn. Stat. § 289A.08, subd. 7a(b)), so the threshold is measured against the interests held by qualifying owners, not against all ownership interests, and a majority of the qualifying owners’ interests can bind a dissenting qualifying owner. And a partner’s adjusted basis and the treatment of distributions are “determined as if the election . . . is not made” (Minn. Stat. § 289A.08, subd. 7a(g)). One caution: the election is available only for tax years beginning after December 31, 2020, and before January 1, 2028 (Minnesota Department of Revenue, Pass-Through Entity (PTE) Tax), so confirm it is live for the year you are planning before you count on it.
Your distributive share of the LLP’s trade-or-business income is generally subject to self-employment tax (Social Security and Medicare) on top of federal and Minnesota income tax. The reason is functional, not a matter of the LLP label. The statutory exclusion reaches only “the distributive share of any item of income or loss of a limited partner, as such” (26 U.S.C. § 1402(a)(13)), and the Tax Court held in Renkemeyer, Campbell & Weaver, LLP v. Commissioner, 136 T.C. 137 (2011), that the attorney partners’ distributive shares “arising from the legal services they performed in their capacity as partners in the law firm are subject to self-employment taxes.” The Tax Court has since confirmed that the same functional test governs even partners formally styled limited partners: “Soroban’s limited partners were limited partners in name only. . . . They are not limited partners within the meaning of section 1402(a)(13).” Soroban Capital Partners LP v. Commissioner, T.C. Memo. 2025-52 (May 28, 2025).
That said, “all of my K-1 is self-employment income” is too broad. Section 1402(a)(1)-(3) excludes rentals from real estate, dividends and interest, and capital gains from net earnings from self-employment, and § 1402(b)(2) exempts a partner whose net earnings from self-employment are under $400 for the year (26 U.S.C. § 1402(a)(1)-(3), (b)(2)). Guaranteed payments for services remain subject to the tax regardless. On the state side, Minnesota taxes partner income at the individual level, and the partnership’s taxable net income “shall be assigned to this state under sections 290.17 to 290.20” (Minn. Stat. § 290.31, subd. 27).
On deadlines, “March 15” is calendar-year shorthand, not the rule. The federal Form 1065 is due the 15th day of the third month after the close of the tax year, which is March 15 for a calendar-year partnership and the 15th day of the third month after a fiscal year closes (26 U.S.C. § 6072(b)). Individual calendar-year returns, by contrast, are due “on or before the 15th day of April following the close of the calendar year,” a full month after the March 15 partnership deadline set in the adjacent subsection (26 U.S.C. § 6072(a)-(b)), which is the point: the K-1s have to reach the partners in time. Minnesota sets no independent date. Partnership returns “must be filed on the due date for filing the federal income tax return” (Minn. Stat. § 289A.18, subd. 1(1)-(3)), a conformity clause that also covers fiscal-year and short-year returns.
Minnesota’s extension is automatic, and conditional. The commissioner “shall grant an automatic extension of six months to file a partnership, ‘S’ corporation, or fiduciary income tax return if all of the taxes imposed on the entity for the year by chapter 290 and section 289A.08, subdivision 7, have been paid by the date prescribed by section 289A.18, subdivision 1” (Minn. Stat. § 289A.19, subd. 1). No application is required, but the extension is conditioned on paying the entity’s taxes by the original due date.
Finally, estimated tax. The trigger is $500 or more, not more than $500: no underpayment addition to tax is imposed “if the tax shown on the return for the taxable year . . . reduced by the credits allowable is less than $500” (Minn. Stat. § 289A.25, subd. 4). Installments are due April 15, June 15, September 15, and January 15 (Minn. Stat. § 289A.25, subd. 3(b)). Two points from the same statute are easy to miss. For you as an individual partner, no underpayment addition is imposed for a taxable year if you had no Minnesota tax liability for the preceding taxable year, that year was a taxable year of 12 months, and you were a resident of Minnesota throughout that preceding year (Minn. Stat. § 289A.25, subd. 6); the carve-out is written for individuals, and it does not relieve the partnership of its own estimated-tax obligation. And the partnership does have an estimated-tax obligation of its own: a partnership “must, when prescribed in subdivision 3, paragraph (b), make payments of estimated tax,” and for a partnership “estimated tax” means the sum of the taxes for the taxable year imposed by chapter 290 (which includes the section 290.0922 minimum fee) and the composite income tax imposed by section 289A.08, subdivision 7 (Minn. Stat. § 289A.25, subd. 1). The composite tax is one component of that sum, not the trigger for the obligation, so a partnership owing only the minimum fee still has one. The underpayment charge is an interest-rate-based addition under Minn. Stat. § 270C.40, not a flat fine (Minn. Stat. § 289A.25, subd. 2).
