Tax Strategies for Spouse Owned Businesses

Owning a business with your spouse can be rewarding but it also comes with unique tax challenges. If your business is unincorporated and profitable, understanding these rules can save you time, stress, and money.

Why Spousal Businesses Face Special Tax Rules

When you and your spouse jointly operate an unincorporated business, the IRS generally treats it as a partnership for federal tax purposes.

• You must file Form 1065 (U.S. Return of Partnership Income) each year.
• Each spouse receives a Schedule K-1, reporting their share of income, deductions, and credits.

This extra paperwork is just the beginning. The real challenge often comes from self-employment taxes.

The Self-Employment Tax Hit

Self-employment tax covers Social Security and Medicare contributions for business owners. For 2025:

• 12.4% Social Security tax applies to the first $176,100 of net self-employment income.
• 2.9% Medicare tax applies to all SE income, increasing to 3.8% if your joint income exceeds $250,000.

If your business earns $300,000 and you split it 50/50, you’ll each pay self-employment tax on $150,000. That’s about $45,900 in self-employment taxes combined on top of regular income tax.

Three Ways to Reduce the Tax Burden

1. Elect Qualified Joint Venture Status (Community Property States)

If you live in a community property state, IRS rules (Rev. Proc. 2002-69) allow you to treat your business as a sole proprietorship for tax purposes. This can significantly cut your SE tax bill.

• All income is reported under one spouse.
• Only the first $176,100 is subject to the 12.4% Social Security tax.

2. Convert to an S-Corporation

Switching from a partnership to an S-Corporation can reduce self-employment taxes because:

• Only salaries paid to you and your spouse are subject to Social Security and Medicare taxes.
• Remaining profits can be distributed as FICA-tax-free dividends.

Keep in mind: S-Corps have additional compliance requirements, so weigh the pros and cons.
