How do I estimate my income for the marketplace?
Last updated September 3, 2026.
Marketplace savings are based on your expected income for the coverage year, not last year, per HealthCare.gov, so you are forecasting. Start from last year's return, adjust for known changes like new jobs, hours, or retirement, and count MAGI: wages, self-employment, unemployment, Social Security, and investment income, with some categories like SSI excluded. Both directions hurt: overestimate and you lose savings monthly, underestimate and you repay at tax time. The protective habit: update your application whenever income changes during the year.
What to do
- Start from last year's tax return, then adjust for known changes.
- Count MAGI: wages, self-employment, Social Security, investments.
- Update the application when income changes; it cuts both ways.
- Expect tax-time reconciliation if your estimate missed.
