Retirement Accounts and Taxes: Traditional vs. Roth (2025)
✅ Reviewed by Marcus Whitfield, Investment & Capital Gains Writer, for accuracy against current IRS guidance.

The whole game is <em>when</em> you're taxed
Retirement accounts don't eliminate tax — they change its timing. A traditional 401(k) or IRA gives you a deduction now and taxes withdrawals later. A Roth gives no deduction now but makes qualified withdrawals in retirement completely tax-free. Choosing between them is really a bet on whether your tax rate is higher today or in retirement.
2025 contribution limits
For 2025 you can contribute up to $23,500 to a 401(k) (plus a $7,500 catch-up at age 50+), and up to $7,000 to an IRA ($8,000 with the catch-up), per the IRS — Retirement Topics: IRA Contribution Limits. Traditional IRA deductibility and Roth eligibility phase out at higher incomes, so check the current thresholds before contributing.
Capture the employer match first
If your employer matches 401(k) contributions, that match is an immediate, guaranteed return — contribute at least enough to capture all of it before funding anything else. Skipping the match leaves free money on the table no investment can replace.
Required minimum distributions
Traditional accounts can't grow tax-deferred forever. Once you reach the RMD age (currently 73), you must withdraw a minimum amount each year and pay tax on it. Roth IRAs have no RMDs during the owner's lifetime — a meaningful advantage for estate planning and flexibility.
A simple order of operations
For many savers the priority is: contribute enough to get the full match, then max an HSA if eligible, then fund a Roth or traditional IRA based on your rate outlook, then return to the 401(k). Adjust for your own income and goals.
Key takeaways
- Traditional gives a deduction now and taxes withdrawals later; Roth is funded with after-tax money but grows tax-free.
- Up to $23,500 for a 401(k) (plus $7,500 catch-up at 50+) and $7,000 for an IRA ($8,000 with catch-up).
- Once you reach RMD age (currently 73), you must withdraw a minimum amount from traditional retirement accounts each year and pay tax on it.
