Will an unexpected large social security disability check in November of 2017 force me to repay the Affordable Care Act Credit I received for Jan thru Nov?

[Coleen3 · Accepted solution]

It is possible. Non-taxable Social Security is taken into consideration on the calculation on Form 8962.

are there things I can do to avoid or reduce the repayment?

[BobinCT]

if you are eligible to make a deductible IRA contribution, this might be a good year to do it.

how large a charitable contribution would it take to offset $15000 tax bill?

[Coleen3]

That will not reduce your AGI. It will potentially reduce your taxable income. You get a percentage of your contribution, depending on your tax bracket. $5,000x 10% bracket = $500 less taxable income.
