How to Save Tax in an LLP: QBI, Section 179, and Retirement

Partners in a Limited Liability Partnership already avoid one layer of tax because the LLP itself pays no federal income tax; profits and losses pass through to each partner’s return and are taxed once at that partner’s rate. Beyond that structural advantage, the practical ways to save tax in an LLP come down to how you pay partners, which deductions you claim, how you time capital purchases, how much you shelter in retirement accounts, and how carefully you handle self-employment tax. Used together, these levers can move a partner’s effective rate by double digits.

Pay Partners Through Guaranteed Payments

Guaranteed payments to partners for services rendered or capital contributed are treated as if paid to an outsider, which lets the LLP deduct them as a business expense.1Office of the Law Revision Counsel. 26 U.S.C. 707 – Transactions Between Partner and Partnership The partnership deducts the full amount, and the receiving partner reports it as ordinary income. The tax benefit shows up when the partner’s marginal rate sits below the effective rate the partnership income would otherwise carry, or when the deduction pulls partnership income below a threshold that unlocks other benefits.

Two conditions matter. The partnership agreement should spell out the amount or formula in writing; without that, the IRS can reclassify the payment as a plain profit distribution and strip the deduction. And the payment has to be reasonable for the work or capital involved. A five-hundred-thousand-dollar guaranteed payment for ten hours of annual work invites an audit adjustment.

Each partner receives a Schedule K-1 showing their share of income, deductions, credits, and guaranteed payments, and reports those figures on their personal return.2Internal Revenue Service. Partner’s Instructions for Schedule K-1 (Form 1065) The IRS receives a copy of every K-1 the partnership files, so any mismatch between the K-1 and the partner’s 1040 is a fast route to an automated notice.

Claim the 20% Qualified Business Income Deduction

Section 199A lets partners deduct up to 20% of their qualified business income from the LLP directly on their individual returns.3Office of the Law Revision Counsel. 26 U.S.C. 199A – Qualified Business Income A partner with $200,000 of qualified income could see up to $40,000 shaved off taxable income before other limitations apply.

Below the income threshold the math is simple: 20% of your share of partnership income. For 2026, the threshold sits around $201,750 for single filers and $403,500 for joint filers. Above those levels, limits tied to the partnership’s W-2 wages and depreciable property basis start phasing in and can shrink or wipe out the deduction.

Specified service businesses face tighter rules. Law, accounting, consulting, health care, and financial services partners lose the deduction entirely once income clears the phase-out range, roughly $276,750 for single filers and $553,500 for joint filers in 2026. Starting in 2026, a minimum QBI deduction of $400 is available to partners who materially participate in an active trade or business and have at least $1,000 of qualified business income, but service business owners are excluded from that floor.

The practical move: if your LLP is bumping up against those thresholds, maxing out retirement contributions or timing deductions to hold taxable income below the phase-in preserves thousands in QBI savings.

Deduct Every Ordinary Business Expense

Every legitimate operating cost the LLP incurs reduces the income that flows through to partners. Rent, utilities, office supplies, software subscriptions, professional services, and insurance premiums all qualify as ordinary and necessary. Signed leases, monthly invoices, and bank statements that tie back to the general ledger give the partnership a defensible position when the IRS asks.

Business meals are deductible at 50% when there is a clear business purpose, such as a client meeting or a working lunch during travel. Keep a log with the date, attendees, and topic. Entertainment is a different category: since the Tax Cuts and Jobs Act, sporting tickets, golf outings, and concerts with clients are fully nondeductible even when the business connection is real. The narrow exceptions are entertainment reported as taxable compensation, company-wide employee events, and entertainment made available to the general public.

Business travel remains deductible, including airfare, lodging, and ground transportation. On mixed-purpose trips, a detailed itinerary showing which days were business-related protects the deduction.

Front-Load Equipment Costs With Section 179 and Bonus Depreciation

When the LLP buys equipment, vehicles, or other tangible business assets, two provisions let the partnership take the deduction now instead of over years.

Section 179 allows the LLP to expense qualifying equipment in the year it is placed in service. For 2026, the maximum deduction is $2,560,000, phasing out dollar-for-dollar once total qualifying purchases exceed $4,090,000. The equipment must be used more than 50% for business, and the deduction cannot exceed the partnership’s taxable income for the year.

Bonus depreciation picks up where Section 179 stops. Under the One Big Beautiful Bill Act signed in July 2025, qualified business property acquired after January 19, 2025, qualifies for permanent 100% bonus depreciation.4Internal Revenue Service. Treasury, IRS Issue Guidance on the Additional First Year Depreciation Deduction Amended as Part of the One Big Beautiful Bill There is no annual dollar cap, and unlike Section 179 the deduction can create a net operating loss that carries forward. For an LLP making a large capital purchase, bonus depreciation can zero out the year’s taxable income.

For assets that qualify for neither method, standard straight-line depreciation still lowers reported profit each year without any cash outflow.

Cut Self-Employment Tax Where You Legally Can

Self-employment tax is the cost most LLP partners underestimate. The combined rate is 15.3%: 12.4% for Social Security on earnings up to $184,500 in 2026, and 2.9% for Medicare on all earnings with no cap.5Social Security Administration. Contribution and Benefit Base Partners who actively participate owe self-employment tax on their entire distributive share plus any guaranteed payments.

The built-in relief: you can deduct half of your self-employment tax when calculating adjusted gross income.6Internal Revenue Service. Topic No. 554, Self-Employment Tax That is not a deduction against the SE tax itself, but it lowers your income tax. On $184,500 of self-employment earnings the half-deduction runs over $14,000 of reduced taxable income.

A larger strategy involves partner classification. Federal law excludes a limited partner’s distributive share from self-employment tax, except for guaranteed payments received for services.7Office of the Law Revision Counsel. 26 U.S.C. 1402 – Definitions Whether that exception reaches LLP partners has been contested for years. A January 2026 Fifth Circuit decision held that state-law partner status controls, regardless of how actively the partner participates. The Tax Court has taken a narrower view, asking whether the partner functions as a passive investor. The law is actively shifting, so any partner counting on this exception should work with a tax advisor tracking case law in their circuit.

Shelter Income Through Retirement Contributions

Retirement plans are the single largest tax reduction lever for most LLP partners, and they are chronically underused. As self-employed individuals, partners can run plans that combine employee deferrals with employer contributions and shelter a large chunk of income from current-year tax.

A solo 401(k) fits LLPs without non-partner employees. In 2026, a partner can defer up to $24,500 as the employee contribution, then add an employer profit-sharing contribution of up to 25% of net self-employment earnings. Partners aged 50 through 59 or over 64 can add $8,000 in catch-up, while those aged 60 through 63 qualify for an enhanced $11,250 catch-up. The combined limit for partners under 50 is $72,000.8Internal Revenue Service. 401(k) Limit Increases to $24,500 for 2026, IRA Limit Increases to $7,500

A SEP IRA is simpler to run but only allows employer-side contributions up to 25% of net self-employment income, capped at $72,000 in 2026.9Internal Revenue Service. COLA Increases for Dollar Limitations on Benefits and Contributions The trade-off: if the LLP has non-partner employees, the same contribution percentage must be applied to all eligible workers, and the match cost can eat into the savings.

Every dollar contributed to a traditional 401(k) or SEP IRA drops the partner’s taxable income for the year. A partner earning $250,000 who contributes the full $72,000 lands at $178,000 before other deductions. That contribution also lowers the income used to figure QBI limits, which can rescue the 20% deduction at the same time.

Deduct Health Insurance Premiums

Partners can deduct the cost of health, dental, and long-term care insurance premiums for themselves and their families. Typically the partnership pays the premiums and reports them on the partner’s K-1 as guaranteed payments; the partner picks the amount up in gross income and takes an above-the-line deduction that cancels it out.10Internal Revenue Service. Instructions for Form 7206 – Self-Employed Health Insurance Deduction The net tax cost on the premium itself is zero, but the deduction lowers adjusted gross income, which can improve eligibility for other income-sensitive benefits.

The policy can be in the partnership’s name or the partner’s. If the partner pays premiums directly, the partnership must reimburse them and report the reimbursement as a guaranteed payment on the K-1. Skip the reimbursement step and the plan is no longer considered established under the business, and the deduction is gone.

Keep Filings and Estimated Payments on Track

Tax savings only stick if the compliance work behind them holds up. The partnership files Form 1065 as an information return showing total income, deductions, credits, and each partner’s allocable share, and issues a Schedule K-1 to every partner.11Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income For calendar-year partnerships, Form 1065 is due March 15, and Form 7004 buys a six-month extension. Missing the deadline without an extension runs $260 per partner per month.

Partners themselves owe quarterly estimated payments covering income tax and self-employment tax on their share of partnership earnings. For 2026, the deadlines are April 15, June 15, and September 15 of 2026, and January 15, 2027.12Internal Revenue Service. 2026 Form 1040-ES Underpaying by more than $1,000 for the year triggers a penalty that functions as interest on the shortfall. Partners with seasonal income can use the annualized income installment method to avoid penalties in lower-income quarters.

One boundary worth naming: aggressive planning and tax fraud are separated by intent, and the IRS treats that line seriously. Civil penalties for negligence, substantial understatement, or fraud can add 20% to 75% on top of the tax owed, plus interest running from the original due date. Willful evasion is a felony under federal law.13Office of the Law Revision Counsel. 26 U.S.C. 7201 – Attempt to Evade or Defeat Tax Document every deduction, keep the partnership agreement current with any payment arrangements to partners, and file on time. If you spot an error after filing, amending voluntarily before the IRS contacts you generally avoids the harshest outcomes.
