The short answer
Your ACA subsidy is based on your estimated annual income, so if your income changes mid-year — a raise, a new job, a business upswing or downturn — your subsidy should change too. The important move is to report the change to the Marketplace promptly. If you don't, you could receive too much subsidy and have to repay it at tax time, or too little and miss out on help you qualified for.
So a mid-year income change is a prompt to update your Marketplace information, not something to ignore.
Why reporting matters
The advance premium tax credit you get monthly is based on your projected income. If your income rises and you keep taking the same subsidy, the extra help gets reconciled at tax time — and you may owe it back. If your income falls, you might be entitled to more subsidy now (lower monthly premiums) that you're not getting. Reporting keeps your subsidy accurate in real time. Our guide to estimating income for ACA subsidies covers the estimate.
Reporting promptly is how you avoid both a surprise repayment and overpaying during the year.
How to report a change
Log in to your Marketplace account and update your income (and household, if that changed). The Marketplace recalculates your subsidy and adjusts your monthly premium going forward. For variable income, revisit your estimate periodically rather than setting it once. Our guide to how subsidies work explains the mechanics.
The takeaway: when your income changes, update the Marketplace so your subsidy stays right and tax time holds no surprises.
Frequently Asked Questions
What happens if my income changes mid-year on an ACA plan?
Your subsidy should change too. Report the change to the Marketplace so your credit adjusts. Otherwise you may repay excess subsidy at tax time or miss out on help you qualified for.
Do I have to report a mid-year raise to the Marketplace?
You should. If you keep taking the same subsidy after a raise, the excess gets reconciled at tax time and you may owe it back. Reporting keeps your subsidy accurate.
