If you're eligible to contribute to an HSA for the entire year, you can contribute up to the annual statutory limit for the type of HDHP coverage you have (self-only or family). If you're age 55 or older, you can make an additional "catch-up" contribution of up to $1,000. If you are not eligible for the entire year, you can still contribute the maximum contribution amount if you remain HSA-eligible throughout a 13-month "testing period." If you do not remain HSA-eligible during the testing period, then the annual limit is prorated to the number of months that you are eligible.
HSA Contribution Limits*
If both you and your spouse have family coverage and are HSA-eligible, one annual family contribution limit applies to both of you and may be split between your HSAs in any way you choose. For example, for 2020, you could contribute $3,550 to your HSA and your spouse could contribute $3,550 to his HSA, for a total of $7,100, the 2020 family contribution limit. Note that if both you and your spouse are each eligible for a catch-up contribution, the catch-up amounts cannot be combined into one HSA.
Contributions can be made in any amount throughout the year until your tax return due date (generally April 15) for that year, not to exceed your annual limit. Any contributions made on your behalf by your employer or anyone else are included in your one annual limit.
As long as you cannot be claimed as a dependent on another person's tax return, you can deduct your own–yourself and your spouse–HSA contributions (not those made by your employer).
*Subject to annual cost-of-living adjustments.
