Money may be deposited to your HSA through payroll deduction, if your employer allows, or you may make deposits directly to your account. Deposits may be made periodically or in a lump sum, but only up to the contribution limits set by the IRS.

• Payroll deductions: If your employer offers the option, you may specify a regular contribution to be deducted from your paycheck. This contribution will be made before Social Security, federal, and most state income taxes are deducted.
• After-tax contributions: You may choose to make all or part of your annual account contributions to your HSA by making “after-tax” contributions to your account. These contributions, which you can make by writing a personal check, may be deducted on your income tax return, using IRS Form 1040 and Form 8889. Employers may make contributions to your account as well; while you do not take a deduction for these contributions, they are excluded from your gross income.

Note: You will use IRS Form 1040 for your HSA contributions, not the short form 1040A or 1040EZ. This deduction is taken “above the line”: you do not need to itemize contributions on Schedule A in order to claim the deduction for HSA contributions.
