Roth IRA Income Limits: The 2026 Math

In 2026 you can contribute the full $7,500 to a Roth IRA if your MAGI is under $153,000 single or $242,000 married joint, and the IRS then shrinks your allowed amount to zero as income rises through the phase-out range. Earn above the top of that range and you cannot contribute directly — but you may still have other options like a backdoor contribution.

TL;DR

• 2026 limits: $7,500 under 50, $8,600 at 50+ — you need at least that much earned income
• MAGI controls eligibility: adjusted gross income plus add-backs decides where you land
• Phase-out zones shrink your contribution from full to zero across $15K single or $10K joint
• Partial math is proportional: the IRS formula is (top − MAGI) ÷ range × limit
• Over the top: you cannot contribute directly, but a backdoor Roth may be an option

What the 2026 numbers are

This is the snapshot to save. The Retirement Accounts hub tracks all 2026 retirement figures — these are the Roth IRA pieces.

Item	2026 figure	What it means
Roth IRA contribution limit (under 50)	$7,500[1]	Max across all IRAs
Catch-up at 50+	$8,600[1]	$7,500 + $1,100 extra
401(k) elective deferral limit	$24,500 ($32,500 at 50+)[2]	Separate from IRA; you can do both
Full Roth if single MAGI	under $153,000[3]	Full $7,500 ($8,600 if 50+)
Full Roth if married joint MAGI	under $242,000[3]	Full amount jointly
Single phase-out	$153,000–$168,000[3]	Partial in this window
Married joint phase-out	$242,000–$252,000[3]	Partial in this window

The takeaway: the dollar limit ($7,500) and the income window ($153K/$242K floors) are separate rules — you must pass both.

You also need earned income at least equal to what you contribute. Earn $5,000 in 2026 and your cap is $5,000 even though the posted limit is $7,500[1].

What MAGI means and why it controls your limit

MAGI is not your salary. It is the tax definition the IRS uses to decide who qualifies.

Start with Adjusted Gross Income (AGI) from your return. Then the IRS adds back a few items for the Roth test — mainly foreign earned income exclusion, foreign housing amounts, and excluded income from Puerto Rico or American Samoa[4]. For most people without those exclusions, MAGI equals AGI.

Why it matters: pre-tax 401(k) contributions lower AGI and thus MAGI, while a year-end bonus or freelance income can push you over a threshold even if base salary is under it. Filing status also changes the range you compare to[3].

If you are close to a limit, estimate MAGI before you contribute. Fixing an excess contribution later means extra paperwork you can avoid.

The phase-out: full, partial, or none

The phase-out is a ramp, not a cliff. Below the bottom you get the full amount. Inside, your limit shrinks proportionally. At or above the top you get zero.

Hold that shape in mind — full → partial → none:

The windows are narrow — $15,000 for single and $10,000 for joint[3] — so a $5,000 raise inside the window cuts a third to a half of your allowed amount.

Here is the full picture for 2026:

Filing status	Full contribution	Partial (reduced)	No direct Roth
Single	MAGI under $153,000[3]	$153,000 to under $168,000[3]	$168,000+[3]
Married filing jointly	MAGI under $242,000[3]	$242,000 to under $252,000[3]	$252,000+[3]
Married filing separately	$0–$10,000 only[3]	$0–$10,000 reduced to zero at $10,000[3]	$10,000+[3]

The takeaway: single at $160,000 MAGI is about halfway through the $15K window — expect roughly half the limit. Joint at $247,000 is halfway through the $10K window — same idea.

Married filing separately is the outlier: $0 to $10,000[3], which blocks direct Roth contributions for most couples who file separately.

How to figure a partial contribution

Inside the phase-out the IRS uses a fraction: how far you are from the top, divided by the range size, times the limit.

For single in 2026:

• Range size = $168,000 − $153,000 = $15,000
• Allowed = ($168,000 − your MAGI) ÷ $15,000 × $7,500 (or $8,600 if 50+)[3]

For married joint:

• Range size = $252,000 − $242,000 = $10,000
• Allowed = ($252,000 − your MAGI) ÷ $10,000 × $7,500[3]

Round up to the next $10; the IRS bumps a small positive result to at least $200 in some cases.

Example — single, MAGI $160,500: ($168,000 − $160,500) = $7,500. $7,500 ÷ $15,000 = 0.50. 0.50 × $7,500 = $3,750 allowed — half the window, half the contribution. Every dollar inside the window reduces what you can add.

Show the math

Single at $160,500: (168,000 − 160,500) ÷ (168,000 − 153,000) × 7,500 = 7,500 ÷ 15,000 × 7,500 = 0.5 × 7,500 = $3,750. Joint at $247,000: (252,000 − 247,000) ÷ (252,000 − 242,000) × 7,500 = 5,000 ÷ 10,000 × 7,500 = $3,750. At 50+ replace 7,500 with 8,600. Round up to next $10 per IRS; hypothetical MAGIs.

Contribute only the allowed amount. An excess contribution triggers a 6% penalty for each year it stays until corrected.

What to do if you are over the limit

Over $168,000 single or $252,000 joint, you cannot contribute directly[3] — but Roth-style saving is not over. Three paths:

1. backdoor Roth contribution. Contribute to a traditional IRA (no income limit to contribute) and convert to Roth[5]. The conversion is taxable on any pre-tax dollars, and the pro-rata rule aggregates all traditional IRAs — so a large pre-tax IRA makes most of the conversion taxable.

2. Max the 401(k). The 2026 elective limit is $24,500 ($32,500 at 50+)[2] with no income phase-out for Roth 401(k) contributions. If you have a workplace plan, filling it to the match is often the higher-dollar move.

3. Use a taxable brokerage for overflow. No limits, no MAGI test. You lose tax-free growth but keep flexibility and the same low-cost funds.

Your 401(k) and Roth IRA caps are separate. Maxing one does not reduce the other — you can do $24,500 plus $7,500 in the same year if you qualify[1][2].

For sequencing — match first, then Roth, then back to the 401(k) — the 401(k) or Roth IRA? tool walks the priority order.

How this fits your retirement plan

The income limit is a filter on how you get Roth dollars, not whether a Roth is good. Under the floor, the direct Roth is simplest: after-tax in, tax-free growth, tax-free qualified withdrawals. That is why how to open a Roth IRA step by step starts there — fund up to $7,500, buy a broad index fund, automate.

Inside the phase-out, the partial still compounds. At 7% for 30 years, $3,750/year grows to roughly $354,000 — half the ~$708,000 from $7,500 (hypothetical, constant return). The same lesson from what is an expense ratio and how does it eat returns applies: consistent contributions beat sporadic ones because time does the work.

Over the top, weigh the backdoor’s tax and reporting cost against adding to a Roth 401(k). The Roth vs Traditional IRA tool models tax now versus later, and what is a target date fund and is it right for me helps with what to buy once funded. Estimate MAGI in the fall — a bonus can still push you into the window with time to adjust.

Bottom line

In 2026 the Roth IRA test is a MAGI check with a narrow ramp: full under $153K single / $242K joint, fading to zero by $168K / $252K, on top of the $7,500 ($8,600 at 50+) cap[1][3].
