Question 49 · Sep 30 · Day 21

Claude on Question 49, Sep 30

What's the 2025 Roth IRA contribution limit if I'm 50, and what's the income phase-out range for a single filer?

2025 Roth IRA Contribution Limit (Age 50)

$8,000 total — that's the $7,000 base limit plus the $1,000 catch-up contribution for anyone age 50 or older.

A couple of notes:

  • •You qualify for the catch-up if you turn 50 at any point during 2025 (i.e., by December 31, 2025).
  • •The $8,000 is a combined limit across all your IRAs — traditional and Roth together, not $8,000 each.
  • •You need at least $8,000 in earned income (wages, self-employment income) for the year. Spousal IRAs are an exception if you're married filing jointly.
  • •Deadline to contribute for 2025: April 15, 2026.

Income Phase-Out for Single Filers (2025)

MAGIWhat you can contribute
Under $150,000Full $8,000
$150,000 – $165,000Reduced (partial) amount
$165,000 or more$0 directly

This same range applies to head of household filers.

For reference, married filing jointly is $236,000 – $246,000, and married filing separately (if you lived with your spouse at any time during the year) is a brutal $0 – $10,000.

If You're Over the Limit

Being phased out of direct contributions doesn't mean you're locked out of a Roth. The backdoor Roth IRA — contributing to a traditional IRA (non-deductible) and then converting to Roth — is a common workaround with no income limit. One big caveat: the pro-rata rule means any existing pre-tax traditional/SEP/SIMPLE IRA balances you hold can make the conversion partially taxable, so it's worth checking your balances first or talking to a tax pro before doing it.

This is general information, not personalized tax advice — your specific situation may have wrinkles worth running by a CPA.
