Question 1

Should I prioritize 401(k), IRA, or HSA contributions first?

Accepted Answer

A common priority order is: contribute enough to your 401(k) to get the full employer match (it's an immediate, guaranteed return), then max out an HSA if you're eligible (triple tax advantage: pre-tax in, tax-free growth, tax-free for medical expenses), then max out an IRA, then return to maxing your 401(k), and finally consider after-tax/mega backdoor Roth contributions if you still have income to save. For example, someone with a 4% 401(k) match, HSA eligibility, and $10,000 in annual savings capacity would first direct 4% of pay to the 401(k) to capture the full match, then fund the HSA up to its annual limit, then contribute to an IRA, and only return to maxing the 401(k) after those higher-priority accounts are filled.

Question 2

Traditional or Roth — how do I decide?

Accepted Answer

Traditional contributions reduce your taxable income now and are taxed on withdrawal in retirement; Roth contributions are made with after-tax dollars but grow and withdraw tax-free. Generally, Roth makes more sense if you expect to be in the same or a higher tax bracket in retirement than you are today; Traditional tends to win if you expect a meaningfully lower bracket later. Many people split contributions between both to hedge against uncertainty in future tax rates. For example, someone early in their career in a lower tax bracket who expects significantly higher earnings by retirement would typically favor Roth contributions today, paying tax now at a low rate rather than later at a higher one — while someone at peak earnings in a high bracket, expecting a lower bracket after retiring, would typically favor Traditional instead.

Question 3

What happens if I contribute more than the annual limit?

Accepted Answer

IRA and HSA excess contributions can incur a recurring 6% excise tax if not properly corrected. That is not the general rule for 401(k) excess elective deferrals: normally the excess and earnings must be distributed by April 15 of the following year, regardless of a tax-return extension, to avoid additional adverse tax treatment. Other plan excesses have different correction procedures. Contact your plan administrator or tax advisor promptly; do not treat every retirement account as having the same penalty or deadline.

Question 4

Do catch-up contributions require anything special?

Accepted Answer

No separate election is usually required — most plans automatically allow catch-up contributions once you turn 50 (or 60-63 for the SECURE 2.0 "super catch-up") as long as you're contributing above the standard limit. Some plans do require you to opt in; check with your plan administrator if your contributions aren't reflecting the higher limit. For example, a 52-year-old contributing above the standard deferral limit typically has their extra contributions automatically treated as age-50 catch-up by the plan with no separate election needed — though it's worth confirming with the plan administrator if contributions ever stop being accepted right at the standard limit instead of the higher catch-up limit.
