My wife and I (late 50s/early 60s) have are own business and are practically semi-retired. Our expected income swings widely, based on project work, etc. After years of buying our own insurance, we went onto an ACA plan last year as our previous year’s income would have (just) qualified for the subsidy (it’s a BCBS plan in IL). Now having just finished our taxes, our actual 2024 income was even lower than the previous year we used to guesstimate our income level, and consequently, our subsidy. Is it possible to “update” your expected income, to increase your subsidy amount, or is it limited to the enrollment period at the end of the calendar year?
