I don’t think the problem here is a result of when the OP pays his “taxes owed”, although the advice given about that is helpful. Because aren’t only about 6% of assets above a certain allowance considered/included in the EFC? If so, the fact that the OP had a poorly timed $9,000 in the bank would have resulted in only about a $500 increase in an EFC - not $5,000. The EFC wouldn’t suddenly increase by $5,000 because of that anyway - the $500 would already be included in the EFC figure.
He stated that he checked and the increase was due to the the college reducing his taxes paid amount by $12,000.
I suspect this might be the problem:
“I tried to use the import function but the FAFSA website choked on it several times so that necessitated self reporting on my part.”
If the FAFSA only considers/wants the “taxes paid” line item, where/how is the “taxes owed” line item considered in the FA process? I’d think it’d be added together for the calculation wouldn’t it? Maybe the OP added the 2016 taxes owed, but paid in 2017 ($9,000) to the taxes paid line item when that amount was already being considered?
I found this info online:
“The FAFSA weights parents’ income much more heavily than parent assets, assessing income according to a scale of 22 to 47 percent of available income”
If the OP fell into that category of having his income assessed at closer to the 47%, then that $9,000/$12,000 added incorrectly to the taxes paid might have resulted in the additional $5,000 in the recalculation.
But that still doesn’t explain why the amount was reduced by $12,000 (instead of $9,000). There’s something else going on for them to reduce the amount by $3K more than the $9,000. If I was the OP, I’d call the FA office to see why they reduced the taxes paid amount by $12,000. Or just compare the FAFSA information to his 2016 tax return.
