The health savings account: three tax breaks and one gate

The account people describe with the most excitement and understand the least. It does something no other account does, and there is a gate in front of it that many people cannot walk through.

More than once I have heard the HSA described as an account with three tax breaks at once, something no other account has, and I have heard it from people who could not say who is allowed to have one. Both things can be true. Let me take the excitement and the gate in turn.

The gate

To put money in, you must be covered by a high deductible health plan as the IRS defines it, and not by other coverage that disqualifies you, including Medicare. Whether your plan counts is written in the plan papers; do not assume it from the word "high." The IRS sets the minimum deductible and the maximum out of pocket each year. If your plan does not meet them, the door is closed, and no amount of enthusiasm opens it.

The three tax breaks

Money you put in is subtracted from your taxable income, and if it goes in through your paycheck it usually skips payroll tax as well. Money inside the account grows without being taxed. Money you take out for medical costs is not taxed either. No other everyday account gets all three. The catch is the third one: spend it on something that is not a qualified medical cost before 65 and you owe income tax plus a penalty. After 65 the penalty goes away and non medical withdrawals are taxed like a traditional IRA.

Here is the quiet trick. There is no deadline for paying yourself back. If you pay a medical bill from your checking account today and keep the receipt, you can pull that same amount out of the HSA tax free in twenty years. People who can afford to pay today's medical bills out of pocket sometimes invest the HSA and let it compound, treating it as a retirement account with a medical exit that is never taxed. This only works if you keep the receipts and can actually absorb the bills now.

The account is yours, not your employer's, and it follows you between jobs. Many HSA providers park your money in cash by default and make you move it into investments on purpose, which brings us right back to the box and the thing inside it.

A made up example

Tomas puts in $3,000 a year, invests it in a broad index fund earning 6 percent, an example rate, and pays his real medical bills from his paycheck for twenty years. He keeps receipts adding up to $25,000. At year twenty the account holds about $110,000. He can pull $25,000 out immediately with no tax, leave the rest growing, and use it later for Medicare premiums and other qualified costs. Change the numbers in the calculator and watch the shape change.

Where the tidy version goes wrong

The excitement skips over the health plan itself. A high deductible plan means you pay more before insurance helps. For someone with steady medical needs and thin savings, three tax breaks may not be worth the bigger bills. The account is wonderful for some people and wrong for others, and the difference is not about the account. It is about the health plan and the household wrapped around it.

Questions worth asking yourself

Does your plan actually meet the IRS definition this year? Does your employer put anything in? Does the provider charge fees, and what can you invest in? Could you pay this year's medical bills without touching the account? And are you keeping receipts somewhere that will still exist in twenty years?
