@fretfulmother, you are not irresponsible.
Last year (our first FAFSA) we waited to do our taxes in early Feb, because all forms should have gotten to us by then. We have fairly simple tax situation, W2 income, 401k contributions. D did not have to file a tax return last year, but did this year.
It did not take that long and you can work on the FAFSA and save info and come back to add stuff. In our tax software I plugged in numbers from the last paystub (or W2) and basically in our case for FAFSA we needed the AGI, income from working (separate if you have two parents working), tax paid, 401k contributions.
So you can add demographic info for student and parent, her school codes, and financials as you have them. Put “will file” and then come back after tax returns are processed and update and import info with the IRS retrieval tool.
The assets will be reported as of the day you submit the FAFSA the first time. I had balances all ready last year, but all we were asked was “did parents’ total assets exceed a certain $ number?” (our asset protection allowance which goes by age), and since we were under that we just said “no”. For D we put her checking acct balance.
That was it. After submitting FAFSA, on the confirmation screen there was a link to the PHEAA (PA state grant form) so we did that as well and we had to print out a form to mail to Harrisburg.
The nice thing was this year, doing a renewal FAFSA, most of the demographic info was already there.
@Mysonsdad, sorry you had a higher income year. Unfortunately 2015 tax info will be used for 2016/17 FAFSA and also 2017/18 FAFSA (available to do this Oct), but maybe if your W is retiring, you can let the schools know that the income is changing and they will make a personal judgment? The higher tax amount works a little in your favor for FAFSA, not sure if it will offset the higher income. Any way you can still contribute to an IRA? Although FAFSA adds that back in.
