Good, if you can file HOH then that should save some on federal taxes. Run a withholding calculator to see if you can up your allowances while still paying enough in.
The Roth IRA doesn’t have to be through your employer, you can open your own account and the contribution would be after-tax. I’m not an expert but I thougt that the contributions can be withdrawn again if needed.
But if you already put maximum in 401k that might be too much. Also I think there are income limits and since your income is increasing that might not be an option.
Ok so this year’s aid won’t change. Your son can take out direct loans and save them. Then next year if grant goes down he can also take loans and I would spend most if the 529. Like others said the asset protection allowance is being reduced a lot, for us it’s going down from $30k to $6k. So why should you be penalized for college savings and borrow from home equity? Then last year you can make up the shortfall from a loan if needed.
year one (income $60k) $25 k merit, $25 k grant
year two (income $60k) $25 k merit, $25 k grant
year three (income $100 k) $25 k merit, $6,500 loan from soph year, $7,500 k junior loan, $11 k 529 acct
year four ($100 k) $25 k merit, $7,500 senior loan, $9 k 529 acct, $8,500 from home equity loan?
So you see you really shouldn’t have to pay anything out of pocket until 4th year, with your son taking $21.5 k in loans, the $20 k in 529 acct, and you paying $8.5 k
I don’t have more time now, but I can look up some links for W4 calculator and Roth IRA for you later.
Don’t worry, a raise is always good! And you do have the merit aid that shouldn’t change!
Your son might even be able to raise that $8k or some of it over the next two summers and maybe get an on campus job as well.
Pat yourself on the back for putting three (?) kids through college as a single parent!
