Paying for implants from an HSA

Pre-tax money cuts the real cost of dental work by your tax rate. For a $4,000 implant paid from an HSA by someone in the 22% federal bracket with a 5% state tax, that's about $1,080 kept in your pocket. The calculator above works it out for your numbers.

What counts

IRS Publication 502 (for 2025 returns) says you can include amounts paid for the prevention and alleviation of dental disease, lists X-rays, fillings, braces, extractions and dentures as examples, and separately includes artificial teeth. Cosmetic surgery generally doesn't count unless it corrects a deformity from a congenital abnormality, an injury or a disfiguring disease, and amounts paid to whiten teeth are excluded (IRS Pub. 502, checked 30 Oct 2026).

Your HSA or FSA administrator may ask for an itemized receipt or a letter of medical necessity.

The limits for 2026 and 2027

Both years are published, so treatment staged across New Year can be planned against the right cap.

Sources: Rev. Proc. 2025-19; Rev. Proc. 2026-24, checked 6 Nov 2026; Rev. Proc. 2025-32; IRS release IR-2026-133, November 5, 2026, checked 6 Nov 2026; 26 U.S.C. 223. The carryover figure is the most a plan may let you roll from that plan year into the next.

An HSA balance builds up over the years, so money saved earlier can pay for an implant later. An FSA usually has to be spent within the plan year, apart from any carryover or grace period your employer offers, which makes it useful when treatment dates are known in advance.

Worked example: a $5,000 plan

Someone with family HSA coverage in the 22% federal bracket and a 5% state income tax. Their dental plan pays $1,500 of a $5,000 implant plan, leaving $3,500.

• Paid from the HSA: $3,500
• Income tax avoided: $3,500 × (22% + 5%) = $945
• If the money went in through payroll, it also skipped the employee's Social Security and Medicare tax (6.2% plus 1.45%, IRS Topic 751), adding about $268. IRS Publication 969 says employer HSA contributions, including those made through a cafeteria plan, generally aren't subject to employment taxes (IRS Pub. 969).

State income tax can treat HSA money differently from federal tax, so check your state's instructions before counting the state part.

The medical expense deduction

If you itemize, the medical and dental costs above 7.5% of your AGI are deductible (IRS Pub. 502). You can't also deduct expenses paid with tax-free HSA money (IRS Pub. 969).

Example. Full-arch treatment of $12,000 in one year, $1,000 of other medical bills, adjusted gross income $60,000. The threshold is $4,500, so $8,500 is deductible if you itemize. If $3,000 of the dental bill came from an HSA, the deductible amount drops to $5,500. The deduction only helps if your itemized deductions beat the standard deduction, which the calculator can't check for you.

Timing tips

1. Schedule staged treatment so the bills fall in the year your FSA is funded.
2. Pay the dentist directly from the HSA card, or pay yourself back later and keep the receipts.
3. For full-arch work, bunching the cost into one tax year makes the 7.5% deduction more likely to help.
4. Ask a tax professional if you're unsure; this page explains the rules, it doesn't apply them to your return.
