Automatic vs Manual HSA Contributions

This question was submitted by HSA reader Adam. Send yours in to evan@hsaedge.com

You explain that contributing to your HSA via automatic payroll contributions is “preferred”, yet you then explain how you choose to contribute manually every month. Is there an advantage to doing it that way?

Either method of contribution will get you to the same place, but there are a few advantages to either. Automatic payroll HSA contributions are defined as deductions from your paycheck each pay period, so you see the contribution amount taken out before taxes are paid on each check. First, if you have automatic payroll contributions, your employer is onboard with the HSA program so there may be the opportunity for employer HSA contributions which would be free money. More generally, contributions made through payroll are “pre-tax” so you immediately recognize tax savings each month (e.g. my taxable income is lower each month, less taxes paid). It also creates a disciplined system where you avoid “forgetting” to contribute, and your contributions are accounted for and organized each month and at year end. Overall it is a more organized, disciplined approach.

My employer never supported HSA contributions so I made manual contributions. To do this, I set an automatic monthly transfer from my bank account to my HSA after my second paycheck. I timed it such in case I needed to cancel the contribution, but doing it after your first pay check is probably more disciplined. These were post-tax dollars being contributed, so I paid taxes upfront and was refunded those taxes once I filed taxes. This creates money “on loan” to the government, but it was nice to get a refund. My HSA provider tracked my contributions for the year, so come tax time I verified this number, plugged it into my filing, and it helped decrease my tax liability for the year. Additionally, manual contributions gives you more flexibility to manage your cash flow. If you are investing your HSA (and know you will maintain coverage for the full year), you could max out your HSA contribution on January 1st, giving your money an extra year to grow. Or you could break it up into quarterly contributions, or contribute at year end with any money leftover.

Either way, after filing taxes your tax liability will be the same, manual contributions just involves paying the government money and then asking for it back.

HSA Contribution Limits If Your Health Insurance Changes Mid Year

This post is based on a great question that came from an HSA Edge reader. Feel free to email any questions you may have to evan@HSAedge.com

We all know that our Health Savings Account has a contribution limit (2014 = $3,300 / $6,550), a maximum amount of tax free contribution that cannot be exceeded during the year. This is all fine and dandy assuming you start the year with an HSA plan and end the year with the same HSA plan. But what if your health insurance changes mid year? How does this affect your HSA? It turns out, changing your health insurance during a fiscal year can have an impact on how much you can contribute. If not followed properly, this can lead you to over contribute, causing painful penalties or taxes.

Below are 3 scenarios that show how changing your health insurance affects your contributions:

1) Sign up for HSA eligible insurance during the year

If you sign up for an HSA eligible health insurance plan during the year, you are on the right track to open a health savings account and begin contributing. You are allowed to make full contributions for a year if you are covered by HSA eligible health insurance on December 1st of that year. This is explained in detail in the post on the Last Month Rule. The summary is that when you start a new HSA eligible health insurance plan, you can contribute up to the maximum contribution limit during the first year if you had coverage on the first day of the last month of the year. In other words, if you have a plan opened by December 1st, you can contribute up to the max.

However, this is enforced by the Testing Period, which says that if you are going to take advantage in that first year and contribute more than your pro-rata share, you have to stay on an HSA eligible plan for a corresponding time during that subsequent year. If not, you have in fact over contributed and penalties / taxes occur. Thus, if you are going to sneak in a full year contribution during your first year on an HSA plan, make sure you are not just a flash in the pan and are planning on staying on that plan for a while.

2) Switch health insurance plans to other HSA eligible plan mid year

This is quite simple: if you change health insurance plans, and both are HSA eligible, there is no effect to your contribution amount for the year. In the IRS’s eyes, you are covered by an HSA eligible plan for the full year, so you are able to make full contributions. The example here is you have an HSA eligible plan Jan > May, but in June you hop on an employer sponsored plan that is also HSA elibile. No problem, go ahead and make full contributions.

However, remember that the test for HSA eligibility occurs on the first of the month. This means that on the first day of each month, if you have HSA insurance and are an eligible individual, you “earn” 1/12th of the maximum contribution limit for that month. It follows that if you have coverage in each month, you earn 12/12 or 100% of the maximum contribution limit for the year. On the other hand, if you make a switch that is not in effect on the first of the month, you will lose that 1/12th of the contribution limit. The effect is your contribution limit is reduced and only equal to those months you have coverage.

The alternative scenario is covered by the final section…

3) Leave a HSA eligible plan mid year

Same scenario, covered by HSA eligible plan Jan > May, but you switch to a health insurance plan that is not HSA eligible in the middle of the year. What then?

This is where things get tricky. While the IRS is not super clear on this, the interpretation is that you are only allowed to contribute to an HSA for the months of a year you remain on the insurance plan. Basically, contribution limits are pro-rata based on the amount of time you are on the plan. If you are single ($3,300 2014 max) on the plan for 6 months, your maximum contribution limit is (6/12 * $3300) = $1,650. If you on the plan for 10 months, your maximum contribution = (10/12 * $3300) = $2,750. You are effectively capped out when you quit the plan to avoid taking advantage of the tax break.

That raises the real risk of penalties and taxes resulting from over-contributing. Consider the following scenario:

  • Strong earner
  • Maxes out HSA contribution early in year
  • Due to unforeseen circumstances, no longer HSA eligible sometime mid year

This presents a real problem for that person as they have in effect over contributed for the year. Even if they were able to reimburse their full contribution against qualified medical expenses, they have deducted too much from their income and will result with over contribution penalties and taxes, which are evil. The advice is you may want to space out your yearly HSA contributions by month / quarter as to avoid the risk of over contribution. This does not mean you cannot reimburse for prior medical expenses. In this scenario, you could incur $3,300 in qualified medical expenses in January and contribute monthly, reimbursing yourself for that $3,300 over time. However, this strategy puts a circuit breaker in the equation should you change health insurance to a non HSA eligible plan mid year, preventing you from penalties and taxes.

How to Lower your Taxes with an HSA

With tax season upon us, many people are looking for ways to decrease their taxes owed. If you have a qualifying High Deductible Health Plan (HDHP), you can use an HSA to reduce your tax liability for the year.

Tax Free Contributions

One of the main tax benefits of HSA’s is that money you contribute is tax exempt. You lower your taxable income by the amount of your HSA contribution. Thus, Health Savings Accounts can allow the total amount you in taxes in a given year.

The mechanics of this can work in two ways:

  1. Automatic HSA Contributions (paycheck) – If your HSA contributions occur via your employer, when your paycheck is processed your HSA allocation will be pre-tax. It is removed form your income, and you pay taxes on the remaining income.

    Thus, your taxable income = [Salary – HSA Contribution].
  2. Manual Contributions – If you contribute to your HSA manually (say, by bank transfer each month), you will have earned the income and already paid taxes on it. Never fear, you will make this up in your tax filing. When you file your taxes (using Form 8889), you will declare how much you contributed to your HSA that year. This will be deducted from your Taxable Income, so you will receive those original payroll taxes back as a refund.

    Again, your taxable income = [Salary – HSA Contirbution].

An Example of HSA Tax Savings

The maximum HSA contribution for 2014 is $3,300. Without an HSA, this $3,300 is earned and taxed as normal income. For example, if your tax rate is 25%, you pay $825 in taxes while the remaining $2,475 goes to your bank account. Federal and State taxes take a sizable amount of your earnings, and you keep 75%.

Using an HSA, you can divert this same $3,300 to a tax advantaged account so that you keep 100% of it. Instead of having money taxed and only $2,475 in your account, you have the whole $3,300. This is a tax savings of $825, or:

Tax Savings = HSA Contribution x Tax Rate

The best part is you own this money and get to keep it forever, unlike some flexible spending accounts. You can use your HSA to pay for many qualified medical expenses tax free. You can invest it and let it grow, and even use it for retirement without penalty (in this scenario, you would defer income taxes until retirement, likely paying taxes at a lower rate than currently). As you can see, you avoid (or defer) paying taxes, which keeps more money in your pocket to save and grow.
