You may not contribute $1000 to one HSA even if you and your spouse are both age 55 or older. The catch-up provision is specific to the individual, and each HSAaccount is owned by only one person. You could contribute $7000 to your account and $1000 to your spouse, or $4000 to each account, or almost any other combination. But you cannot contribute more than $7000 to any one individual account or more than $8000 total.
