Health Savings Accounts (HSAs) offer a tax-advantaged way to save for medical expenses, but exceeding contribution limits can lead to financial complications. Many account holders inadvertently surpass these thresholds, resulting in excess contributions that need addressing.
Understanding the reasons behind these overages is crucial for maintaining compliance and avoiding penalties.
Maximum Contribution Threshold
Navigating HSA contributions requires familiarity with the IRS’s maximum thresholds. For 2025, individuals with self-only coverage can contribute up to $4,300, while those with family coverage can contribute up to $8,550. Individuals aged 55 and older can also make an additional $1,000 catch-up contribution, and each spouse must use their own HSA to make their own catch-up amount.1Internal Revenue Service. Rev. Proc. 2024-25 (2025 HSA Adjustments)2Internal Revenue Service. Publication 15-B (2025), Employer’s Tax Guide to Fringe Benefits
These limits are adjusted annually for inflation, reflecting changes in healthcare costs and economic trends. Staying informed about IRS updates is essential for effective financial planning.
Common Triggers of Excess
Excess contributions often occur due to uncoordinated contributions from multiple sources. For example, when both an employer and employee contribute, or when spouses contribute to separate HSAs, it’s easy to exceed IRS limits. If an employer contributes $1,000 to an employee’s HSA, the employee must adjust their contributions accordingly. Automatic payroll deductions can further complicate this issue.
Mid-year changes in health plan coverage can also cause overages. Switching from self-only to family coverage—or vice versa—requires adjusting contributions to align with the new limit. Failure to do so may result in excess contributions.
Misunderstanding catch-up contributions for those aged 55 and over is another common error. The catch-up provision applies individually, not to households. If both spouses are eligible and have separate HSAs, each can contribute an additional $1,000. Confusion often leads to only one spouse making the full contribution, resulting in miscalculations.
Potential Tax and Penalty Issues
Exceeding HSA contribution limits triggers tax implications and penalties. The IRS applies a 6% excise tax on excess contributions that remain in the account at year-end. You can avoid this excise tax if you withdraw the excess and any earnings by your tax return due date (including extensions), and include the earnings in income for the year withdrawn.3Internal Revenue Service.

Excess contributions must be reported on IRS Form 5329, which calculates the excise tax owed if any excess remains. Inaccurate reporting can lead to further penalties and interest.4Internal Revenue Service. Instructions for Form 5329 (2024)
Earnings generated from excess contributions are considered taxable income. If not corrected promptly, account holders face both the excise tax on the excess and income tax on the earnings. Addressing overages quickly minimizes these liabilities.
Methods to Correct the Surplus
Correcting an HSA surplus begins with reviewing account statements to identify the overage. Contacting the HSA custodian to withdraw excess funds is crucial, as custodians have specific procedures and deadlines.
Removing excess contributions before the tax filing deadline, including extensions, can help avoid penalties. If addressed within this timeframe, the excise tax may be waived. Account holders must also calculate earnings from the excess contributions, as these are taxable.
Establishing preventative measures can avoid future issues. Setting up alerts or reminders to monitor contributions is one approach. Consulting a tax advisor or financial planner can provide guidance on optimizing HSA contributions while adhering to IRS rules.
Documentation for Accuracy
Maintaining accurate documentation is essential for preventing and addressing excess contributions. Detailed records of all HSA-related transactions, including bank statements, contribution receipts, and employer contribution summaries, help identify discrepancies and protect against IRS audits.
Employer contributions should be cross-referenced with personal records to ensure accuracy. Any discrepancies should be resolved with the employer or HSA custodian. Using accounting software or apps to track contributions in real-time can streamline this process and reduce errors.
Leveraging tax resources like IRS publications or professional tax software can enhance record-keeping accuracy. Consulting a tax professional provides tailored advice for managing HSAs effectively, ensuring compliance with IRS regulations while optimizing benefits.
