They want you to estimate 2024 income now. It gets reconciled to actual spring 2025. You can update the estimate through the year as needed.If you’re filling this in during annual enrollment for coverage to start Jan 1, are you supposed to fill in current year income amounts or estimate of next year income? Specifically, if 2023 is final year employed, income is very high but will drop drastically in 2024 when retired. If I use the lower numbers will it cause a problem when they get my 2023 tax return and see much higher numbers, or they will only care about 2024 income when they get that tax return in spring of 2025?
