Self-Employment Taxes for business Partnerships in the "DMV" area
Starting and running a business partnership in the DMV area—comprising Washington D.C., Maryland, and Virginia—comes with many financial responsibilities. One of the most important is understanding self-employment taxes. These taxes can significantly affect your income and how you manage your business finances. This post breaks down what self-employment taxes mean for partnerships in this region, how they work, and practical steps to handle them effectively.

What Are Self-Employment Taxes?
Self-employment taxes cover Social Security and Medicare taxes for individuals who work for themselves. Unlike employees whose employers withhold these taxes from their paychecks, self-employed individuals must calculate and pay these taxes themselves. For partnerships, this means each partner is responsible for paying self-employment tax on their share of the business income.
The self-employment tax rate is currently 15.3%, which includes:
12.4% for Social Security tax
2.9% for Medicare tax
If your net earnings exceed a certain threshold, an additional 0.9% Medicare tax applies.
How Self-Employment Taxes Apply to Partnerships
In a partnership, the business itself does not pay income tax. Instead, profits and losses pass through to the partners, who report them on their personal tax returns. Each partner pays self-employment tax on their share of the partnership’s income, assuming they are actively involved in the business.
Key Points for Partnerships in the DMV Area
Active partners pay self-employment tax on their distributive share of income.
Limited partners who do not participate in business operations generally do not pay self-employment tax on their share.
The partnership files an informational return (Form 1065), but partners report income on Schedule K-1.
Partners use Schedule SE to calculate self-employment tax on their individual returns.
Calculating Self-Employment Tax for Partners
To calculate self-employment tax, partners need to determine their net earnings from self-employment. This is generally the partner’s share of partnership income minus allowable business expenses.
Example Calculation
Suppose a partnership in Arlington, Virginia, earns $200,000 in net income, split evenly between two partners who both actively work in the business.
Each partner’s share: $100,000
Self-employment tax rate: 15.3%
Self-employment tax per partner: $100,000 × 15.3% = $15,300
Each partner would owe $15,300 in self-employment taxes, in addition to income tax on their share.
State and Local Tax Considerations in the DMV
The DMV area includes three jurisdictions with different tax rules that affect partnerships and self-employment taxes.
Washington D.C.
D.C. imposes income tax on residents and businesses.
Self-employed partners must file D.C. personal income tax returns.
D.C. does not have a separate self-employment tax but includes income from self-employment in taxable income.
Maryland
Maryland taxes personal income, including income from partnerships.
Self-employed individuals must pay Maryland state income tax on their share.
Some counties in Maryland have local income taxes that apply.
Virginia
Virginia taxes personal income, including partnership income.
Self-employed partners pay Virginia state income tax.
No separate self-employment tax at the state level.
Understanding these state and local tax rules is essential for partners to comply fully and avoid penalties.

Tips for Managing Self-Employment Taxes in Partnerships
Handling self-employment taxes can be complex, but these tips help partners stay on track:
Keep detailed records of income and expenses to accurately calculate net earnings.
Make quarterly estimated tax payments to avoid penalties and interest.
Consult a tax professional familiar with DMV tax laws for personalized advice.

Failing to pay estimated taxes quarterly can lead to large tax bills and penalties.
Misclassifying partners as limited or active can cause incorrect tax treatment.
