If you and your spouse own an LLC together in a non-community property state, the IRS treats it as a partnership by default. That means filing Form 1065 each year, issuing a Schedule K-1 to each spouse, and paying self-employment tax on each spouse’s share of the profits. The simplified options that some married co-owners hear about, including the Qualified Joint Venture election and the community-property disregarded-entity treatment, are not available to you. You can, however, elect S-corporation or C-corporation taxation to change that default.
Why the Simplified Married-Couple Options Don’t Apply
Two shortcuts exist for married co-owners, and neither one reaches a husband-and-wife LLC in a common law state.
The Qualified Joint Venture election under Section 761(f) lets certain married co-owners skip partnership filing and report their shares on separate Schedule C forms attached to a joint 1040. One of its requirements is that the business cannot be held in the name of a state law entity like a partnership or an LLC.1Internal Revenue Service. Married Couples in Business That disqualifies every husband-and-wife LLC, regardless of state.
Revenue Procedure 2002-69 fills the gap for couples in the nine community property states (Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin) by letting a wholly community-property-owned LLC be treated as a disregarded entity, reported on a single Schedule C.2Internal Revenue Service. Revenue Procedure 2002-69 That relief does not extend to the roughly 40 common law states. If your LLC was formed anywhere else, the IRS treats it as a multi-member entity from day one.3Internal Revenue Service. Election for Married Couples Unincorporated Businesses
The Partnership Default: What You File
Without an election, your LLC files Form 1065, U.S. Return of Partnership Income, reporting the business’s total income, deductions, and credits. The form itself does not generate a tax bill. Partnerships are pass-throughs, so tax falls on the individual partners.
Each spouse gets a Schedule K-1 showing their distributive share. Those amounts flow onto Form 1040, typically through Schedule E. Even filing jointly, both K-1s must be prepared and attached. The partnership return is informational, but late filing carries its own penalty independent of any tax owed.
Self-Employment Tax on Both Spouses
This is where the partnership default hurts. Each spouse is treated as a general partner and owes self-employment tax on their entire distributive share of net earnings. The SE tax rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.4Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) Each spouse calculates it on their own Schedule SE filed with the joint 1040.
The Social Security portion applies only to net earnings up to $184,500 per person in 2026.5Social Security Administration. Contribution and Benefit Base Above that cap, the 2.9% Medicare portion continues with no ceiling. If combined self-employment income on a joint return exceeds $250,000, an additional 0.9% Medicare surtax applies to the excess.6Internal Revenue Service. Topic No. 560, Additional Medicare Tax
A partial offset: you can deduct half of the SE tax as an above-the-line adjustment on Form 1040. That deduction reduces adjusted gross income but does not reduce the SE tax itself. For most husband-and-wife LLCs, the SE tax on every dollar of profit is the single biggest reason to look at the S-corporation election.
Filing Deadlines and the Per-Partner Late Penalty
Form 1065 is due on the 15th day of the third month after the tax year ends. For a calendar-year LLC, that is March 15, shifting to the next business day when it falls on a weekend or holiday. A six-month extension to September 15 is available on Form 7004, but the extension delays only the return, not any tax owed by the partners.
The late-filing penalty scales with the number of partners. For returns due after December 31, 2025, the IRS charges $255 per partner for each month or partial month the return is late, up to 12 months.7Internal Revenue Service. Failure to File Penalty For a two-partner LLC, that is $510 per month and a maximum of $6,120. The penalty applies even in a loss year, because timely filing of the informational return is a standalone obligation.
Both spouses also owe quarterly estimated payments if they expect to owe $1,000 or more in combined income and SE tax for the year. The 2026 estimated deadlines are April 15, June 15, and September 15 of 2026, plus January 15, 2027.8Internal Revenue Service. 2026 Form 1040-ES – Estimated Tax for Individuals Missing them triggers underpayment penalties calculated quarter by quarter.
Electing S-Corporation Status
The most common way out of the SE tax problem is electing S-corporation treatment. The LLC files Form 2553 and, if accepted, begins reporting on Form 1120-S instead of Form 1065.9Internal Revenue Service. About Form 2553, Election by a Small Business Corporation State-law liability protection is unchanged. Only the federal tax classification shifts.
How the Election Saves on Employment Taxes
Business income splits into two buckets: W-2 wages and shareholder distributions. Both spouses, if actively working in the business, must draw a salary reflecting reasonable compensation for the services they perform. FICA applies to those wages. The remaining profit distributed to the spouses as shareholders is generally not subject to self-employment or FICA tax. On a profitable LLC, that split can save thousands per year.
The IRS scrutinizes reasonable-compensation levels closely. Courts have repeatedly held that S-corporation shareholders who perform substantial services cannot set artificially low salaries to avoid employment taxes.10Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers The salary should reflect what you would pay someone else for the same work. Setting it too low invites reclassification of distributions as wages, plus back taxes, interest, and penalties.
Deadline for the Election
For an existing LLC wanting the election to take effect for the current tax year, Form 2553 must be filed by the 15th day of the third month of that year, which is March 15 for calendar-year entities. New LLCs have 75 days from formation. Miss that window and the election takes effect the following year, absent late-election relief.
What the Election Adds
You will run payroll for both working spouses, withhold income tax and FICA, file quarterly Form 941 returns, and issue W-2s at year-end. The business files Form 1120-S annually, due on the same March 15 schedule as Form 1065 with the same six-month extension.11Internal Revenue Service. Starting or Ending a Business Most couples find the added compliance worthwhile once profits comfortably exceed both spouses’ combined reasonable salaries.
Health Insurance for Shareholder-Employees
If the S-corporation pays health insurance premiums for a shareholder-employee who owns more than 2% of the company, which both spouses in a husband-and-wife LLC typically do, those premiums must be included in the shareholder’s W-2 as taxable wages. The shareholder can then claim an above-the-line deduction for the same premiums on their personal return, making the cost deductible without itemizing.12Internal Revenue Service. S Corporation Compensation and Medical Insurance Issues The deduction is not available if either spouse is eligible for a subsidized health plan through another employer.
Electing C-Corporation Status
A husband-and-wife LLC can also elect C-corporation taxation by filing Form 8832.13Internal Revenue Service. About Form 8832, Entity Classification Election The business files Form 1120 and pays tax at the flat 21% federal corporate rate. The C-corp is not a pass-through, so the business itself owes tax on its profits.
The drawback is double taxation. When after-tax profits are distributed to the spouses as dividends, those dividends are taxed again on the personal return. For most small family businesses that distribute most of their earnings, this second layer makes C-corp treatment more expensive than either the partnership default or the S-corp alternative.
The structure occasionally makes sense when a business plans to reinvest most of its profits rather than distribute them, since retained earnings are taxed only once at 21%. C-corporations also allow certain fringe benefit deductions, including fully deductible health insurance for owner-employees, that S-corp and partnership treatment do not. These advantages are narrow enough that the C-corp election rarely fits a two-person family business unless the growth strategy specifically calls for it.
How the QBI Deduction Interacts with Your Choice
Whether the LLC stays a partnership or elects S-corp treatment, both are pass-throughs and both may qualify for the Section 199A Qualified Business Income deduction. Eligible owners can deduct up to 20% of qualified business income on their personal return. On $200,000 of qualifying income, that reaches up to $40,000.
The deduction phases out at higher income levels. For married couples filing jointly in 2026, the phase-out begins at $403,500 of taxable income and full elimination hits at $553,500. Certain service-based businesses, including law, accounting, health care, and consulting, face additional restrictions once the owner enters the phase-out range. Below the lower threshold, the type of business does not matter and the full 20% applies.
One planning wrinkle under the S-corp election: W-2 wages paid to shareholder-employees do not count as qualified business income. Only the pass-through profit on the K-1 qualifies. Setting salaries high and leaving little as distribution shrinks the QBI deduction. Balancing reasonable compensation against QBI eligibility is one of the trickier exercises for S-corp husband-and-wife LLCs, and often the point where professional advice pays for itself.
Keeping the Liability Shield Intact
Federal tax classification is separate from the state-law protection the LLC gives you, but that protection only holds if the business runs as a genuine entity separate from the owners’ personal finances. Courts can disregard the LLC, sometimes called “piercing the veil,” when spouses treat business and personal funds interchangeably.
- Keep separate bank accounts. The LLC needs its own dedicated accounts. No depositing business revenue into a personal account, and no paying personal expenses from the business account.
- Get and use a dedicated EIN for tax reporting, banking, and hiring.14Internal Revenue Service. Employer Identification Number
- Sign contracts, leases, and vendor agreements in the LLC’s name, with a member acting on behalf of the LLC rather than personally.
Commingling funds is the fastest way to lose liability protection, and it’s the mistake husband-and-wife LLCs make most often because the boundary between household and business spending feels artificial when both owners live under the same roof. Separate credit cards, separate bookkeeping, and documented transactions for any money moving between the owners and the company are what keep the shield intact if it’s ever tested.
