Scenario: A Married Couple Co-Owns a Business

This page describes a composite hypothetical. It is not a real client or a real result. All facts and numbers are assumptions used to explain the reasoning.

The Scenario in Brief

A married couple runs a small design business together. Both spouses work in the business, and they have never formally decided how it should be taxed. It operates through a limited liability company with two members. They ask an advisor whether their current setup is right and what the alternatives look like. This scenario walks through the choices.

Assumptions Used

• The couple files a joint return and lives in a state that is not a community property state.
• The LLC has two members, each owning 50 percent, and has never made an entity classification election.
• Net profit is 160,000 dollars, and both spouses materially participate.
• They have no employees other than themselves.
• They are interested in retirement savings and want clear Social Security earnings records for each spouse.

What the Default Rules Say

An LLC with two owners is generally taxed as a partnership by default, so the couple would generally file a partnership return, Form 1065, and issue a Schedule K-1 to each spouse. Each spouse would generally pay self-employment tax on a share of the profit. If the couple had not been filing a partnership return, that would be the first issue for the advisor to address, since a missed partnership filing can carry penalties, and the advisor would discuss how to correct it and what relief may be available.

Alternatives the Advisor Would Explain

Continue as a partnership. The couple files a partnership return each year and reports K-1 income. This is the default and offers flexibility in allocation, but it involves an additional return and requires attention to capital accounts.

Qualified joint venture. Spouses who jointly own and operate an unincorporated business, and who both materially participate, may be able to elect to be treated as a qualified joint venture. Each spouse then reports their share on their own Schedule C, avoiding a partnership return. The election is available only for certain arrangements, and it does not apply to an entity taxed as a corporation. Whether it is available to an LLC owned by spouses depends on state law and on how the LLC is treated, and the advisor would check the details.

One spouse owner, other spouse employee. The business might be owned by one spouse, who employs the other. The employed spouse would receive wages through payroll, and the employer would withhold payroll tax. This arrangement can simplify reporting but changes the way earnings are recorded for Social Security purposes.

S corporation election. The couple might consider an S corporation election, with each spouse paid a reasonable salary. Whether that saves tax depends on the analysis discussed in other scenarios, and it adds payroll and compliance duties.

Worked Arithmetic: Self-Employment Tax Split

Under the partnership or qualified joint venture approaches, the 160,000 dollars might be divided equally, with 80,000 dollars for each spouse. The self-employment tax for each is computed on 92.35 percent of 80,000, or 73,880 dollars, at 15.3 percent, which is about 11,304 dollars per spouse, or about 22,608 dollars in total. If the business were reported entirely by one spouse, the tax base would be 92.35 percent of 160,000, or 147,760 dollars, and the tax at 15.3 percent would be about 22,607 dollars, if below the wage base. So splitting the income does not reduce the tax here, but it does give each spouse their own earnings record, and it can matter for retirement contributions, since each spouse's earnings support their own plan contributions. The figures ignore the wage base, deductions, and other items.

Retirement Planning Effects

If each spouse has earned income, each can generally contribute to a retirement plan based on their own earnings. A solo 401(k) can cover both spouses in a business with no other employees. The advisor would discuss how the choice of structure affects each spouse's contribution capacity.

Scenario Variations Worth Considering

If the couple lived in a community property state, the treatment of a spouse-owned business can differ, and the advisor would review the state rules. If the couple planned to hire employees, the structure might need to change. If the couple planned to sell the business, a partnership or corporation would raise different issues from a sole proprietorship.

Risks and Limits

• The qualified joint venture election is not available in every case.
• Failing to file a required partnership return can result in penalties.
• The best structure depends on state law and on the couple's goals.

What This Scenario Teaches

Ownership and reporting arrangements for spouses are more nuanced than they seem. A short conversation with an advisor can prevent missed filings and can align the tax treatment with the couple's goals for retirement and Social Security records.

Questions to Bring to Your Advisor

1. How should we be classified today, and have we filed the right returns?
2. Are we eligible for qualified joint venture treatment?
3. How does each option affect our retirement plans?
4. What would change if we hired employees?
