Question: are 401k catch up contributions tax deductible?
Answer: Roth 401(k) Catch-Up Contributions Catch-up contributions can also be made to Roth 401(k)s. While you don't get an immediate tax break on the money you contribute to a Roth 401(k), you won't have to pay income tax on the investment growth in the account and can set yourself up for tax-free withdrawals in retirement.
