# 2025 HSA contribution limits: $4,300 / $8,550

The 2025 HSA and HDHP amounts, and the prorated contribution limit for every count of eligible months from 1 to 12.

For the 2025 tax year the HSA contribution limit is $4,300 with self-only HDHP coverage and $8,550 with family coverage; anyone aged 55 or over at the end of the year may add $1,000 to their own HSA. A 2025 HDHP needs a deductible of at least $1,650 (self-only) or $3,300 (family), with annual out-of-pocket no more than $8,300 or $16,600. Contributions for 2025 may be made until Wednesday, April 15, 2026.

## The 2025 proration table

A month counts when you had qualifying HDHP coverage on its first day and no disqualifying coverage. The limit is the annual amount times eligible months divided by twelve, rounded to the dollar.
