In reviewing your application, the Marketplace will compare the amount of income you estimate for next year to the most recent information about your income that is available (usually, that will be the tax return you filed this year reporting last year’s income.) If that amount differs from the amount you put on your application by more than 50% or $12,000 (whichever is greater), you might receive a data match inconsistency notice from the Marketplace and you’ll need to provide more documentation.

In cases of an income data match inconsistency, the Marketplace will ask you to provide documentation within 90 days. If you need an extension beyond 90 days, the Marketplace will grant you an automatic extension for another 60 days while you gather documentation. During that period, you can get premium tax credits based on the income you attested to in your application. However, if you have not resolved the data match inconsistency within 150 days, the Marketplace will adjust or end your advance premium tax credit based on the most recent income information it can find.

State-based Marketplaces may have their own standards around data match inconsistencies. Click here for the link to the websites for State-based Marketplaces. If you are unsure if you reside in a State-based Marketplace or in a state where the Marketplace is offered on the federal platform (also known as Healthcare.gov state or State-Based Marketplace-Federal Platform), click here for more information.
