Collect Your HSA & Coverage Details
Bring together your personal info, HSA account statements, employer contributions, and your High-Deductible Health Plan (HDHP) coverage months. Note your contribution amounts, any catch-up amounts (age 55+), and distributions with receipts. Having this ready makes Form 8889 fast and accurate.
Details worth checking
HSA Eligibility & HDHP Coverage Gaps
Contributing while not eligible (no HDHP, disqualifying coverage, or coverage gaps) can invalidate deductions and trigger additional taxes. Missing the testing period under the last-month rule can also create surprise liabilities.
Contribution Limits Exceeded
Going over the annual limit (self-only vs. family) or forgetting catch-up rules leads to excess contributions, potential excise taxes, and amended-return cleanup.
Employer Contributions Misreported
Misplacing employer HSA contributions (or double-counting them) skews your deduction and can cause IRS mismatch notices.
Untracked or Non-Qualified Distributions
Reporting distributions without receipts—or using HSA funds for non-qualified expenses—can create taxable income and additional taxes.
Missed Excess-Contribution Cleanup
Leaving excess contributions unaddressed can trigger ongoing excise taxes and require amended returns later.
Coverage Months & Proration Errors
If you weren’t eligible all year, your limit may need proration. Getting this wrong changes your deduction and can prompt IRS follow-ups.
Forgetting to File Form 8889
Any HSA contribution or distribution generally requires Form 8889. Omitting it causes delays and correspondence from the IRS.
Name/SSN Mismatches & Missing Signatures
Typos in personal data or unsigned forms can stall processing and create avoidable notices.
Weak Documentation for Audits
Missing receipts for distributions or unclear employer records make audits painful and can lead to reclassifications.
