Estimating self-employment income for a Marketplace health plan application

If you buy health coverage through the Health Insurance Marketplace, the savings you receive depend on the income you expect for the coverage year. For employees with steady wages, that is straightforward. For the self-employed, it means forecasting a number that changes month to month. This guide explains how to build a sensible estimate and what to do when reality differs.

What the Marketplace asks for

HealthCare.gov asks self-employed applicants to include the income they expect to make from their business after expenses. It also explains that Marketplace savings are based on estimated net income for the year you are getting coverage, not last year's income.

Net income is what you would report as profit on Schedule C: business income minus deductible business expenses. If expenses are higher than income, that is a net loss.

The Marketplace uses a figure called modified adjusted gross income to determine eligibility for savings. The application guides you through which other household income to include, such as wages, most retirement withdrawals and net rental income.

Step 1: start with your history

Gather:

• last year's Schedule C
• this year's year-to-date profit and loss statement
• signed contracts or retainers for the coming year

History shows seasonality and your typical expense ratio.

Step 2: project month by month

A simple spreadsheet works:

1. list each month of the coverage year
2. estimate income for each, starting with booked work and regular clients
3. add a realistic allowance for new work, based on past patterns
4. estimate business expenses for each month
5. total the year

HealthCare.gov suggests basing the estimate on past experience, realistic expectations and industry standards. Avoid both best-case and worst-case thinking; aim for what is most likely.

Step 3: add household income

Include income for everyone in your tax household that the application asks for, such as a spouse's wages. Follow the HealthCare.gov list of what to include and what to leave out.

Step 4: document it

Write a short note explaining how you reached your estimate: the history you used, contracts you counted, and assumptions about new work. Keep it with your records. If your actual income later differs, the note shows you made a reasonable estimate.

Step 5: update during the year

HealthCare.gov says that if your yearly net income looks like it will be higher or lower than estimated, you should update your Marketplace application as soon as possible. Changes in income, household members, or offers of other coverage can affect what you qualify for.

A practical routine:

• compare actual year-to-date profit with your estimate each quarter
• if the annual projection has moved meaningfully, update the application
• note the date and reason for each update

Why accuracy matters

The premium tax credit you receive in advance during the year is an estimate. When you file your tax return, it is reconciled against your actual income. HealthCare.gov explains that if you make more than you reported, you could have to pay back some or all of the premium tax credits you took, and if you make less, you could qualify for more savings than you claimed.

The guide to the premium tax credit explains the reconciliation in more detail.

Ways to reduce surprises

• Update promptly when a large contract starts or ends.
• Set aside a cushion if your income is especially uncertain.
• Consider taking less of the credit in advance. HealthCare.gov says you can use all, some or none of your premium tax credit in advance, and claim the rest when you file.
• Keep business and personal finances separate so your profit is easy to measure.

Business deductions affect the number

Because the Marketplace uses net income, legitimate business expenses reduce the figure. Track expenses carefully throughout the year. Do not inflate or invent expenses; your Marketplace estimate should be consistent with what you will report on your tax return.

Choosing a plan

Once your estimate is in, compare plans on total expected cost, not just premium. The guide to Marketplace health insurance covers enrollment periods and plan types.

Estimate net self-employment income for the coverage year from your history and booked work, document how you did it, update the application when income changes, and expect the credit to be reconciled on your tax return.
