What is Form 8889 for?
Form 8889 reports all activity for your Health Savings Account during the 2021 tax year. The Internal Revenue Service requires this form when an eligible individual uses a high-deductible health plan and needs to document HSA contributions, employer contributions, HSA distributions, or qualified medical expenses paid. It also determines your HSA deduction, evaluates excess contributions, and confirms that you follow all tax-favored health plan rules while using tax-free dollars for qualified medical expenses.
When You’d Use Form 8889
You file Form 8889 when you make HSA contributions, receive employer contributions, or use employee payroll contributions through a cafeteria plan. You also file when you take HSA distributions, use a qualified HSA funding distribution, or rely on a rollover contribution. Most taxpayers must include this form, even if they are spending only on medical or dental expenses. If you submit a late or amended tax return, you include Form 8889 to correct missed entries or document excess contributions that require adjustment for the correct tax year.
Key Rules or Details for 2021
- Eligibility rules: An eligible individual must use a high-deductible health plan with an applicable minimum deductible and no other health care coverage. These requirements ensure the health plan qualifies and does not restrict payments for HSA use.
- Contribution limits: Contribution limits depend on whether you have self-only coverage or family coverage, and both you and your employer contribute within the maximum amount allowed. These limits prevent issues related to excess contributions and ensure accurate reporting throughout the tax year.
- Qualified medical expenses: Funds from health savings accounts must be used to pay qualified medical expenses and medical and dental expenses allowed under Internal Revenue Service rules. These expenses include approved medical care services and help prevent additional tax liabilities.
- Distribution rules: HSA distributions remain tax-free dollars when matched to a qualified medical expense. Nonqualified spending creates additional income and possible penalties, which can increase your taxable income on your tax return.
- Testing-period rules: The last month rule allows a full year’s contribution amount when eligible in December. You must maintain HDHP coverage through the following year to avoid penalties under testing-period requirements.

Step-by-Step (High Level)
Step 1: Enter your coverage status
You start by selecting self-only or family coverage, and this determines your minimum annual deductible and contribution amount. This step confirms whether your high-deductible health plan meets eligibility requirements for all plan years beginning in 2021.
Step 2: Report personal and employer contributions
You list HSA contributions made personally, employer contributions deposited on the employer's behalf, and employee payroll contributions. This ensures that your savings account transactions match Internal Revenue Service reporting and avoid excess contributions related to your healthcare coverage.
Step 3: Calculate your deduction and contribution limit
You apply the contribution limit based on whether you selected self-only or family coverage, and you include any additional contributions if you are fifty-five years old or older. This determines your HSA deduction and confirms that deductible contributions meet maximum contribution rules.
Step 4: Enter distributions and match them to expenses
You report HSA distributions and compare each withdrawal with qualified medical expenses paid during the tax year. This prevents additional tax by verifying that every qualified medical expense follows Internal Revenue Service requirements.
Step 5: Review special cases and testing rules
You review any qualified HSA funding distributions, traditional IRA transfers, or Medicare Advantage MSA considerations. This ensures proper reporting when handling only one qualified HSA or coordinating separate HSAs when filing jointly.

Common Mistakes and How to Avoid Them
- Exceeding contribution limits: Many taxpayers exceed the maximum contribution because they overlook employer contributions through payroll or a cafeteria plan. You can avoid this by tracking every contribution amount and comparing totals to contribution limits before completing your tax return.
- Using funds for non-qualified expenses: Non-qualified spending includes items unrelated to medical care services or remote care services. You can prevent this mistake by reviewing Internal Revenue Service rules for each qualified medical expense and keeping receipts for all amounts paid.
- Failing testing-period requirements: Taxpayers sometimes fail to maintain HDHP coverage after using the last month rule. You can avoid this by confirming you maintain HDHP coverage for the entire testing period before using full-year HSA contributions.
- Incorrect distribution reporting: Distributions are often misreported when amounts paid are confused with a rollover contribution. You can prevent this by reviewing Form 1099-SA and matching each HSA distribution with approved qualified medical expenses.

What Happens After You File
After filing Form 8889, your HSA deduction reduces taxable income on your Form 1040. The Internal Revenue Service reviews reports of contributions submitted by trustees for accuracy and compares them to your form instructions. If mismatches occur, the agency may request clarification regarding medical and dental expenses, contribution limits, or separate coverage details. Proper recording of your healthcare activity for the tax year relies on accurate reporting.

A health plan qualifies only when meeting high-deductible health plan rules, and dental expenses count only when treated as a qualified medical expense. Proper classification helps ensure compliance.

Contribution limits define the base maximum amount, and an additional contribution allows for increased deposits for qualified individuals. This helps eligible taxpayers save money on healthcare.
