<p>You need to update the tax info on a transaction that includes the first 10 colleges. Once you remove those 10 colleges, they will no longer receive any corrections made to your FAFSA. I suggest you keep track of the most recent transaction numbers for each set of colleges. If you are selected for verification and/or are asked by a college to use the IRS Data Retrieval Tool, you will need to make sure you actually do it on a transaction that includes that college.</p>
