Claude on Question 49, Sep 11

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

•$7,000 base limit
•$1,000 catch-up contribution (you qualify if you turn 50 at any point during 2025)

One caveat: your contribution can't exceed your taxable compensation for the year. If you earned $5,000, that's your cap.

2025 income phase-out for single filers (and head of household):

Modified AGI	What you can contribute
Under $150,000	Full $8,000
$150,000 – $165,000	Reduced amount
$165,000 or more	$0 directly

If you're in the phase-out range, the math works like this: multiply $8,000 by the fraction of the range you have left. For example, at a MAGI of $157,500 you're halfway through the $15,000 window, so you could contribute about $4,000. (Technically you round up to the nearest $10, and if the result comes out above $0 but under $200, you can still contribute $200.)

A couple of other things worth knowing:

•Deadline: April 15, 2026 for 2025 contributions — you have time.
•Over the limit? A backdoor Roth (non-deductible traditional IRA contribution converted to Roth) is the usual workaround, but watch out for the pro-rata rule if you have existing pre-tax IRA balances — it can make the conversion partly taxable.
•Combined limit: The $8,000 is shared across all your IRAs (traditional + Roth), not per account.

For reference, married filing jointly phases out at $236,000–$246,000 in 2025.
