What do I do if my application has a Data Matching Issue (DMI)?

How to handle and resolve verification notices from the marketplace.

A Data Matching Issue (DMI), also known as an inconsistency notice, means the marketplace needs additional verification for information on your application—such as income, citizenship, legal presence, or identity.

To resolve a DMI, you must upload acceptable documentation (like tax returns, recent pay stubs, passport, or immigration forms) to your online marketplace portal within the required timeframe to avoid losing coverage or subsidies.
