Federal tax

Terry Says

Absolutely, your contributions to a 40l(k) reduce your income –they are a deduction. BUT, it is too late to do that for 2022 now, although you should be contributing for 2023 from your paycheck (and especially if your employer matches your contribution).

As for the IRA you can open an IRA account and deduct your contributions on your 2022 tax return, up until the date the return is due (April 15th). BUT, there are some income limits for being able to make a tax-deductible IRA contribution if you are also covered by a plan at work.
Since I don’t now about your other income, here is a link to the income limits for that IRA contribution to be deductible:
