How much should you contribute?
The simple answer: contribute as much as you can afford, up to the limit. Every dollar you put into an HSA reduces your taxable income by that dollar. For someone in the 22% federal tax bracket contributing the $4,300 individual maximum, that's $946 in federal tax savings alone — before state taxes.
Mid-year enrollment: the pro-rata rule
If you became eligible for an HSA mid-year by switching to an HDHP, you don't get the full annual limit. You get 1/12 of the annual limit for each month you were eligible. However, if you're enrolled in an HDHP on December 1st, the "last month rule" allows you to contribute the full annual amount — as long as you stay enrolled in an HDHP for the entire following year.
Where does HSA money come from?
Contributions can come from three sources, all up to the combined annual limit:
- Payroll deduction: Pre-tax, before FICA taxes — the most tax-efficient method
- Direct contribution: You contribute post-tax, then deduct on your tax return
- Employer contributions: Free money — counts toward your annual limit
Best approach: Contribute via payroll deduction if possible. This avoids both income tax AND the 7.65% FICA tax (Social Security + Medicare), making it more tax-efficient than a post-tax contribution with a later deduction.
