How often can I contribute? Is there a limit as to how much I deposit with each contribution?

If you are an active employee making before-tax payroll deductions, you contribute each pay period. If you are a retiree or want to make after-tax contributions, you can contribute as often as you want, as long as total contributions don’t exceed the IRS maximum. HSA contributions are tax-deductible up to the IRS maximums for single or family coverage. You are responsible for ensuring that your contributions do not exceed these maximums.
