Should I contribute to a 401(k) or Roth IRA first?

The optimal order is: 1) 401(k) up to employer match (free money), 2) Roth IRA up to the limit, 3) then max out 401(k). If you're in a high tax bracket and expect lower taxes in retirement, prioritize traditional 401(k). If you're in a low bracket now, prioritize Roth.

What are the 401(k) and Roth IRA limits for 2026?

In 2026, you can contribute up to $23,500 to a 401(k) ($31,000 if 50+) and up to $7,000 to a Roth IRA ($8,000 if 50+). These are separate limits — you can max out both.

Can I have both a 401(k) and a Roth IRA?

Yes, you can contribute to both a 401(k) and a Roth IRA in the same year. They have separate contribution limits. However, Roth IRA contributions phase out at higher incomes.

401(k) vs Roth IRA: Which Is Better for You? (2026 Guide)

Choosing between a 401(k) and Roth IRA — or figuring out how much to put in each — is one of the most important retirement decisions you’ll make. This guide helps you understand the key differences and optimize your strategy.

401(k) vs Roth IRA at a Glance

Feature	401(k)	Roth IRA
2026 contribution limit	$23,500 ($31,000 if 50+)	$7,000 ($8,000 if 50+)
Employer match	Yes	No
Tax benefit timing	Now (tax-deferred)	Later (tax-free withdrawals)
Income limits	None for traditional	$165,000 single / $246,000 married
Investment options	Limited to plan	Almost unlimited
Required minimum distributions	Yes, at age 73	No
Early withdrawal penalty	10% + taxes	Contributions can be withdrawn anytime
Loan option	Usually available	No

How Each Account Works

Traditional 401(k)

Step	What Happens
Contribute	Pre-tax dollars reduce your taxable income today
Grow	Investments grow tax-deferred
Withdraw	Pay ordinary income tax on entire withdrawal
Required	Must start withdrawals at age 73 (RMDs)

Roth IRA

Step	What Happens
Contribute	After-tax dollars (no immediate tax break)
Grow	Investments grow tax-free
Withdraw	Qualified withdrawals are 100% tax-free
Required	No RMDs for original owner

2026 Contribution Limits

Account	Under 50	Age 50+	Super Catch-Up (60-63)
401(k)	$23,500	$31,000	$34,750
Roth IRA	$7,000	$8,000	$8,000
Total possible	$30,500	$39,000	$42,750

Roth IRA limits may be reduced or eliminated at higher incomes.

Roth IRA Income Phase-Outs (2026)

Filing Status	Full Contribution	Partial Contribution	No Contribution
Single	Under $150,000	$150,000-$165,000	Over $165,000
Married filing jointly	Under $236,000	$236,000-$246,000	Over $246,000

High earner workaround: Use the “backdoor Roth IRA” — contribute to a traditional IRA, then convert to Roth. Or use Roth 401(k) if your employer offers one.

Tax Impact Comparison

Example: $10,000 Annual Contribution

Assumptions: 25% tax bracket now, 22% in retirement, 7% annual return, 30-year horizon

Factor	Traditional 401(k)	Roth IRA
Amount contributed	$10,000	$10,000
Tax savings today	$2,500	$0
Actual out-of-pocket	$7,500	$10,000
Value after 30 years	$76,123	$76,123
Taxes on withdrawal	$16,747 (22%)	$0
Net after taxes	$59,376	$76,123

In this scenario, Roth wins because the tax rate dropped. But if you invest the $2,500 tax savings from the 401(k), results may differ.

When Traditional 401(k) Wins

Scenario	Why Traditional Is Better
High income now, lower in retirement	Defer taxes to lower-rate years
Near top tax bracket (32%+)	Large immediate tax savings
State income tax now, no state tax in retirement	Avoid state tax entirely
Need to reduce AGI	For ACA subsidies, other benefits

When Roth IRA Wins

Scenario	Why Roth Is Better
Lower income now, higher expected later	Pay taxes at lower rate
Early career (lower bracket)	Lock in low tax rate
Want tax diversification	Balance pre-tax and post-tax
Expect higher future tax rates	Hedge against tax increases
Want flexibility in retirement	No RMDs, tax-free income
May need early access	Contributions withdrawable anytime

The Employer Match Factor

Always Get the Full Match First

Employer Match	Your Contribution	Match Value	Total
50% up to 6%	$6,000 (6% of $100k)	$3,000	$9,000
100% up to 3%	$3,000 (3% of $100k)	$3,000	$6,000
100% up to 6%	$6,000 (6% of $100k)	$6,000	$12,000

The match is a 50-100% instant return — no investment beats this. Always contribute enough to get the full match before funding other accounts.

Vesting Schedules

Vesting Type	How It Works
Immediate	Match is yours right away
Cliff (3 years)	0% until year 3, then 100%
Graded (6 years)	20% per year starting year 2

Key insight: If you might leave soon, factor unvested match into your calculations.

Optimal Contribution Strategy

The Standard Priority Order

Priority	Action	Why
1	401(k) to employer match	50-100% immediate return
2	Roth IRA to maximum	Tax-free growth, flexibility
3	401(k) to maximum	Additional pre-tax savings
4	After-tax 401(k) / Mega backdoor	If available
5	Taxable brokerage	Unlimited, flexible

Alternative Strategies by Situation

Your Situation	Recommended Strategy
Entry-level salary (<$50k)	Match → Roth IRA → More 401(k)
Mid-career, good income	Match → Roth IRA → Max 401(k)
High earner (>$150k single)	Match → Backdoor Roth → Max 401(k)
Very high earner (>$250k)	Max 401(k) → Backdoor Roth → Mega backdoor
Expecting income drop soon	Max Roth 401(k) and Roth IRA now
Already have large 401(k)	Prioritize Roth for tax diversification

Investment Options Compared

401(k) Limitations

Aspect	Typical 401(k)	Roth IRA
Number of fund options	15-30	Thousands
Index fund availability	Usually some	All available
Expense ratios	0.03%-1.0%+	0.03%-0.20% (you choose)
Individual stocks	Rarely	Yes
ETFs	Sometimes	Yes
Alternative investments	No	Some (specialty custodians)

Expense Ratio Impact

Expense Ratio	$10,000 After 30 Years (7% return)
0.03% (low)	$74,014
0.20% (average index)	$70,673
0.50% (higher)	$65,001
1.00% (high)	$57,435

High 401(k) fees can cost you tens of thousands over a career.

Withdrawal Rules

Accessing Your Money Early

Account	Contributions	Earnings	Penalty Exceptions
Roth IRA	Anytime, tax-free	Age 59½ + 5 years	First home, education, disability
401(k)	10% penalty + taxes	10% penalty + taxes	Rule of 55, hardship, disability

Roth IRA Flexibility

Scenario	Can You Withdraw?
Need your contributions back	Yes, anytime, no penalty
Need earnings before 59½	10% penalty + taxes (usually)
First home purchase (up to $10k earnings)	Yes, if 5-year rule met
Qualified education expenses	Still penalized (unlike traditional IRA)

401(k) Loan Option

Factor	Details
Maximum loan	50% of balance or $50,000, whichever is less
Repayment period	5 years (15 for home purchase)
Interest rate	Prime + 1%, paid to yourself
Risk	If you leave job, may be due in full

401(k) loans can be useful but have significant risks if you change jobs.

Tax Diversification Strategy

Why You Want Both Pre-Tax and Roth

Tax Situation in Retirement	Optimal Withdrawal Strategy
Low taxable income year	Withdraw from traditional (fill low brackets)
High income year (RMDs, pensions)	Withdraw from Roth (avoid higher bracket)
Need large sum	Mix sources to control tax bracket
ACA subsidy eligible	Draw from Roth to keep income low

Ideal Balance by Age

Age	Suggested Split	Reasoning
20s	70% Roth / 30% Traditional	Low tax bracket now
30s	50% Roth / 50% Traditional	Building balance
40s	40% Roth / 60% Traditional	Higher bracket, tax savings
50s	30% Roth / 70% Traditional	Maximize pre-tax + catch-up
60+	Roth conversions	Convert in low-income years

Roth Conversions

What Is a Roth Conversion?

Move money from traditional 401(k)/IRA to Roth IRA, paying taxes now for tax-free growth later.

Good Time to Convert	Bad Time to Convert
Low income year (job loss, sabbatical)	High income year
Early retirement before Social Security	Already in high bracket
Market is down	Large conversion would push into higher bracket
Tax rates expected to rise	Need the money soon

Conversion Example

Factor	Amount
Amount to convert	$50,000
Current marginal rate	22%
Tax owed on conversion	$11,000
Future tax-free balance	$50,000 + all growth
