Roth IRA Contribution Limits

A Roth IRA is one of the most powerful retirement accounts available: your money grows tax-free, withdrawals in retirement are tax-free, and there are no required minimum distributions. But unlike a 401(k), where your contribution limit is fixed regardless of income, the Roth IRA has two separate constraints — a dollar limit on how much you can contribute, and an income limit that can reduce or eliminate that amount entirely.

Understanding both is the starting point for building a Roth IRA strategy.

The 2026 Roth IRA Contribution Limit

For 2026, the IRS increased the contribution limit for all IRAs:

• $7,500 per person (under age 50)
• $8,600 per person (age 50 and older — the $1,100 catch-up contribution)

This limit applies to your combined contributions across all IRAs — traditional and Roth — for the year. If you contribute $3,000 to a traditional IRA and $4,500 to a Roth IRA, you have hit the $7,500 ceiling for the year. You cannot contribute $7,500 to each.

The limit applies per person, not per household. A married couple can each contribute up to $7,500 for a combined $15,000 — as long as each spouse has at least that much in earned income, or the household has sufficient combined earned income under the spousal IRA rules.

What the Catch-Up Contribution Means

The $1,100 catch-up contribution is available to anyone who is age 50 or older by December 31 of the tax year. It is not automatic — you simply contribute the higher amount, up to $8,600 total. You do not need to be "behind" on retirement savings to use it.

For tech workers approaching 50 with significant pre-tax retirement balances, the catch-up provision is a straightforward way to shift more money into tax-free growth each year. Over a 10-year window from age 50 to 60, the additional $1,100 per year — compounding tax-free — adds meaningful value to a Roth balance.

Your Taxable Compensation Is the Other Cap

The contribution limit is the lesser of $7,500 (or $8,600) and your taxable compensation for the year. If your earned income is below the IRS limit, your maximum contribution equals your income.

Example: A single filer who works part-time and earns $4,200 in 2026 can contribute up to $4,200 to a Roth IRA — not $7,500 — because their compensation is the binding constraint.

Taxable compensation includes wages, salary, RSU income at vest, bonus income, and self-employment income. It does not include investment income, dividends, capital gains, rental income, or pension income. A retiree living entirely on portfolio income and Social Security has zero compensation for IRA purposes and cannot make a new contribution.

How Income Affects Your Contribution Limit

Once your Modified Adjusted Gross Income (MAGI) exceeds a threshold, the IRS reduces your Roth IRA contribution limit proportionally. Above the upper threshold, direct contributions are eliminated entirely.

2026 Roth IRA phase-out ranges:

Most senior tech workers exceed these thresholds. The income limits are covered in detail in Roth IRA Income Limits.

How the Phase-Out Reduces Your Limit

Within the phase-out range, your contribution limit is reduced proportionally. The calculation:

1. Subtract the phase-out start from your MAGI
2. Divide by the range width ($10,000 for most filers, $15,000 for single filers)
3. Multiply by the full contribution limit
4. Subtract that amount from the full limit — the remainder is your reduced limit

Example: Single filer, MAGI of $160,000 in 2026. The phase-out range is $153,000–$168,000 — a $15,000 window. They are $7,000 into the range, or 46.7% through it. Their reduced limit is approximately $7,500 × (1 − 0.467) = $4,000.

One rounding rule: if your calculated limit is more than $0 but less than $200, the IRS rounds it up to $200. You are never in a partial position where you can contribute less than $200.

Roth IRA vs. Roth 401(k): Contribution Limits Compared

A Roth 401(k) — the after-tax designated Roth option inside your employer's plan — has no income limit. Any employee can contribute regardless of MAGI. But the contribution limits are different:

• Roth IRA: $7,500 per person in 2026
• Roth 401(k): Up to $24,500 per person in 2026 (shared with pre-tax 401(k) contributions)

These limits are independent — contributing to a Roth 401(k) does not reduce your Roth IRA limit. Tech workers who earn above the Roth IRA income threshold typically use both: Roth 401(k) contributions during working years, plus the backdoor Roth IRA for the additional $7,500 annually in tax-free growth.

When Contributions Can Be Made

You can make Roth IRA contributions for a tax year at any time during that year, or up to the tax filing deadline of the following year — not including extensions.

For the 2026 tax year, contributions can be made between January 1, 2026 and April 15, 2027.

Contributing early in the year gives your money more time to compound tax-free. A $7,500 contribution made in January versus April earns an extra 3.5 months of tax-free growth — a small difference in any single year, but meaningful compounded across a decade of early contributions.

What Happens If You Contribute Too Much

An excess contribution occurs if you contribute more than your limit — either because you exceeded the dollar cap, your income eliminated your eligibility, or your compensation was lower than your contribution amount.

Excess contributions are subject to a 6% excise tax for each year the excess remains in the account. To avoid the tax, you must withdraw the excess contribution and any earnings it generated by the tax filing deadline, including extensions.

If you realize after filing that you made an excess contribution, you still have time to act: the IRS allows corrections within 6 months of the original filing deadline if you amend your return.

The Spousal IRA: Contributing for a Non-Working Spouse

Roth IRA contributions require earned income — but there is an important exception. If you file a joint return and your spouse has little or no earned income, you can contribute to a Roth IRA on their behalf, as long as your combined household earned income is sufficient to cover both contributions.

Example: One spouse earns $200,000 and the other has no earned income. If household MAGI is below $242,000, the working spouse can contribute $7,500 to their own Roth IRA and $7,500 to a spousal Roth IRA — $15,000 total into tax-free accounts for the year.

The spousal Roth IRA is a separate account in the non-working spouse's name. Each spouse has their own contribution limit, catch-up eligibility, and 5-year clock.
