Step 1: Always Get the Full Employer Match
If your employer offers any 401(k) matching contribution, contribute at least enough to capture the entire match before funding anything else — including a Roth IRA. A common match structure is 50% or 100% of your contribution up to some percentage of salary (for example, "100% match on the first 4% you contribute"). That match is an immediate, guaranteed return on your money that no brokerage account, IRA, or investment strategy can replicate: contributing 4% of salary to get a 100% match instantly doubles that portion of your contribution before it's even invested.
How a 401(k) Works
A 401(k) is an employer-sponsored retirement account. Traditional 401(k) contributions are pre-tax — they reduce your taxable income now, grow tax-deferred, and are taxed as ordinary income when withdrawn in retirement. Many employers also offer a Roth 401(k) option: contributions are after-tax, but qualified withdrawals in retirement are entirely tax-free. Contribution limits are set annually by the IRS and are typically higher than IRA limits, with an additional "catch-up" amount allowed for savers aged 50 and over — confirm the current-year limits at irs.gov since they're adjusted for inflation each year.
How a Roth IRA Works
A Roth IRA is an individual account you open yourself (not tied to an employer), funded with after-tax dollars. Contributions grow tax-free, and qualified withdrawals in retirement — both contributions and earnings — are entirely tax-free, with no required minimum distributions during the original owner's lifetime. Roth IRA contribution limits are lower than 401(k) limits and are subject to income phase-out limits: above certain income thresholds (adjusted annually), your ability to contribute directly is reduced or eliminated (though a "backdoor Roth" conversion strategy exists for higher earners — worth discussing with a tax professional given its complexity).
401(k) vs Roth IRA: Side by Side
| Feature | Traditional 401(k) | Roth IRA |
|---|---|---|
| Tax treatment | Pre-tax now, taxed at withdrawal | After-tax now, tax-free at withdrawal |
| Employer match available? | Yes, if offered | No — it's an individual account |
| Annual contribution limit | Higher (set annually by IRS) | Lower (set annually by IRS) |
| Income limits to contribute? | No | Yes — phases out above certain income |
| Investment choice | Limited to plan's fund menu | Broad — any brokerage, any fund/stock |
| Fees | Can be higher (plan administration fees) | Often lower (you choose the low-cost provider) |
| Required minimum distributions | Yes, in retirement (for traditional accounts) | No, during original owner's lifetime |
The Standard Order of Operations
- 401(k) up to the full employer match — guaranteed, immediate return; never skip this.
- Pay off high-interest debt (generally anything above roughly 7-8% APR, like most credit card debt) — the guaranteed "return" of eliminating that interest usually beats likely investment returns.
- Max out a Roth IRA (if income-eligible) — broader investment choice, typically lower fees, and tax-free growth.
- Return to the 401(k) and contribute up to the annual maximum — once the Roth IRA is maxed, additional retirement savings usually goes back to the 401(k) for its higher contribution ceiling and the convenience of automatic payroll deduction.
- Taxable brokerage account — for savings beyond what tax-advantaged accounts allow.
This order isn't universal law — it's the common-sense sequencing most fee-only financial planners suggest because it captures guaranteed benefits (the match, then debt payoff) before moving to accounts ranked by their tax efficiency and flexibility.
Worked Example
An employee earning $60,000/year has an employer that matches 100% of the first 4% contributed, and can save $400/month total for retirement ($4,800/year):
| Step | Allocation | Annual Amount |
|---|---|---|
| 1. 401(k) to capture full match | 4% of $60,000 | $2,400 (plus $2,400 employer match = $4,800 total) |
| 2. Remaining budget to Roth IRA | $4,800 − $2,400 | $2,400 into Roth IRA |
| Total retirement contributions | $4,800 saved by employee, $7,200 total invested with match |
Notice this employee only had to personally set aside $4,800 to end up with $7,200 actually invested — the employer match added 50% more money for free, simply by directing savings to the 401(k) first up to the match threshold.
Roth IRA Income Limits
Roth IRA eligibility phases out above income thresholds that the IRS adjusts annually for inflation — always check the current-year limits at irs.gov rather than relying on a remembered figure, since they change most years. If your income is above the phase-out range, a "backdoor Roth IRA" (contributing to a traditional IRA, then converting it to Roth) is a commonly used workaround, though it has tax nuances — particularly the "pro-rata rule" if you have other pre-tax IRA balances — that make consulting a tax professional worthwhile before attempting it.
When It Makes Sense to Deviate
- No employer match offered: the Roth IRA vs 401(k) decision becomes primarily about fees, investment choice, and expected future tax rate — a Roth IRA is often preferred first if you're income-eligible.
- You expect to be in a much higher tax bracket in retirement than you are now (early career, expect significant income growth): Roth contributions (paying tax now at a lower rate) become relatively more attractive.
- You expect a lower tax bracket in retirement (peak earning years now): traditional pre-tax 401(k) contributions become relatively more attractive, since you get the deduction now at a higher marginal rate.
- Your 401(k) plan has unusually low fees and strong fund options: the usual "Roth IRA is better than the 401(k) beyond the match" reasoning weakens, and maxing the 401(k) directly may be simpler and just as effective.
Vesting Schedules: The Match You Haven't Fully Earned Yet
Not all employer match money is yours immediately — many plans use a vesting schedule, meaning you only keep 100% of the matched (employer-contributed) funds after working for the company for a certain period. Common structures include:
- Immediate vesting: the match is 100% yours as soon as it's deposited.
- Cliff vesting: you own 0% of the match until a specific milestone (often around 3 years), at which point you become 100% vested all at once.
- Graded vesting: you gradually own an increasing percentage of the match each year (for example, 20% per year over 5 years) until fully vested.
Your own contributions are always 100% yours immediately regardless of vesting — vesting schedules only ever apply to the employer's matching contribution. This matters most if you're considering leaving a job: check your plan's vesting schedule before you resign, since leaving just before a vesting milestone can mean forfeiting matched funds you'd have kept by staying a few more months.
The HSA: A Third Retirement Vehicle
If you're enrolled in a qualifying high-deductible health plan, a Health Savings Account (HSA) offers a rare "triple tax advantage" that some financial planners rank even above a Roth IRA in the savings order of operations: contributions are pre-tax (or tax-deductible), growth is tax-free, and withdrawals are tax-free when used for qualified medical expenses — with no expiration on funds, unlike a Flexible Spending Account. After age 65, HSA funds can also be withdrawn for any purpose without penalty (though non-medical withdrawals are then taxed as ordinary income, similar to a traditional 401(k)), which makes an HSA function as a supplemental retirement account once your working years are behind you. If you have access to an HSA and can afford to pay current medical expenses out of pocket while letting the HSA balance grow invested, some planners suggest funding it even before (or alongside) a Roth IRA, given the additional tax-free-in and tax-free-out treatment for medical costs that a Roth IRA doesn't offer.
