Hi dd9253,
Thanks for the question. The question you ask is really a personal choice. It will take less cash to simply pay the tax. However, if your goal is to pay less tax and to not pay or reduce any associated estimated tax penalties, by all means make an IRA contribution.
If you are in a 12% marginal tax bracket, $10,000 in deductible IRAs will only save $1,200 (22% rate would save $2,200). You could make an estimated tax payment before 1/15/23 to help a little. I would urge to consider the following things:
I hope this helps, please ask any additional questions you need.
You can't contribute more than $7000 to an IRA in 2022--$6000 general plus $1000 catch-up.
You also must have compensation from working, which you did not mention one way or the other.
A $7000 contribution will save probably $800-$1500 in income taxes.
If you are eligible to contribute to a qualified retirement plan at work (401k, 403b, etc) and you are not maxed out for the year, you might try and supersize your contributions for your last couple of paychecks, because that does not count agains your $7000 IRA contribution limit.
