<p>I don’t know what your school did, so I can’t comment on that. I just know how the FAFSA formula works. </p>
<p>Again, the reason they ask for earned income from both spouses is because the formula calculates the FICA for each and subtracts that out. </p>
<p>Self employment tax is 2X FICA – so the 50% deduction from income works to subtract the rest out.</p>
<p>So let’s say hypothetically a person pays $10,000 SE tax.</p>
<p>The amount they report as earned income allows the formula to derive $5000, which is subtracted out from AGI.</p>
<p>Their AGI is calculated after subtracting out the other $5000.</p>
<p>So the full $10K is subtracted out. </p>
<p>You can see the whole formula here:

<p>Look at worksheet A. They derive “total income” by using the AGI (item #1) to provide the “taxable income” in item #3, and adding in untaxed income - item #4. Then the Social Security tax allowance is subtracted out (based on table A2) in lines 10 & 11. </p>
<p>If your college had a copy of your tax returns when making the correction, then it’s possible that they were correcting for an error made in FAFSA entry – if you entered “total income” rather than AGI in the FAFSA, then they would correct for that by entering AGI instead. It can be confusing precisely because the AGI figure is often below the total of the earned income, so I can see how many people probably get confused by that. </p>
<p>Of course it is also possible that your college made an error, or that they exercised professional judgment in you favor based on the overall situation, leaving you with the impression that it was because of the SE tax.</p>
