Your Adult Children on your Family Insurance can have their own HSA

Overview

Did you know that if your adult children are covered by your HSA eligible family health insurance, they likely can open their own HSA? You read that correctly. A common misconception is that only the policy holder can open a Health Savings Account. This is not true, as a review of the HSA guidelines reveals that this restriction to the policy holder (read: you) does not exist. Said another way:

Every independent (tax) person on an HSA Family Plan can open their own HSA and contribute the full year amount.

With the (un)Affordable Care Act mandating that children be allowed to remain on parent HSA insurance plans until age 26, more and more adult children are opting for this and staying on parent plans longer. The good news is, if they are no longer your tax dependent, they can open their own HSA, and anyone can contribute to another’s HSA account. That means that even if junior is in university and making no money, he can still receive up to $6,750 into his HSA account for 2015 from his loving mom or dad, or grandparent, or whoever.

The mechanics of your child having an HSA

So how does this work? The mechanics lie within the definition of and eligible individual, or who can open an HSA, provided by friendly Publication 969. An eligible individual is defined as one who:

  1. is covered under a High Deductible Health Plan (HDHP)
  2. has no other health insurance
  3. is not enrolled in Medicare
  4. cannot be claimed as a dependent on someone else’s tax return (important)

The key one is really #4, in that an HSA holder cannot be claimed as a dependent on someone else’s tax return. Unfortunately, due to this you cannot open an HSA for your young child or children and begin saving for them. You have to wait until they are filing their own taxes. Other than that, the first 3 should almost always apply to adult children. If all 4 of these are true, your adult child qualified as an eligible individual even though they are on your health insurance. That means they can open their own Health Savings Account and begin saving – or you can begin saving for them.

Child HSA Example – Simple

Let’s assume that you are married and have one child who is not longer your dependent. To keep things simple, assume you have had HSA eligible family insurance for everyone for a while (so no Last Month Rule effects) and you are smart and have your own HSA, but your spouse does not. For 2016, the contribution limit for family insurance is $6,750. As such the following maximum HSA contributions are allowed:

  • You – $6,750
  • Child – $6,750

Note that the above amounts end up in 2 different Health Savings Accounts – one for you, and one for your adult child.

Children HSA Example – Complicated

Now assume that you are married and have two adult children and everyone is on your HSA eligible family insurance. Let’s assume you began that insurance on July 1st (exactly mid year) so the Last Month Rule is eligible for this year. Both you and your wife are smart and have your own separate HSA’s, and thus due to Line 6 of Form 8889 you must share the maximum contribution amount between these two accounts. Note that this does not affect your children. For 2016, the contribution limit for family insurance is $6,750. As such the following maximum HSA contributions are allowed:

  • You & spouse – contributions to both HSA accounts cannot exceed $6,750
  • Child 1 – $6,750
  • Child 2 – $6,750

A couple things of note. You and your spouse are limited to a $6,750 between your accounts (so $3,375/$3,375, or $6,750 / $0 would both work). Also notice that your children can each contribute up to the family contribution limit, separate from you and your spouse’s limitation. This is the big advantage here.

An important note: it is my duty to explain the Last Month Rule here. Since coverage began in July, you are freely allowed to contribute 6/12 x $6,750 = $3,375 for the year for each of these accounts. However, you have the option to use the Last Month Rule and contribute the full $6,750 to each account, but you must maintain coverage for the following year. Otherwise, any amount over contributed to each account can be taxed and penalized.

Reasons to establish Health Savings Accounts for your children

There are a wide number or reasons to establish and contribute to an HSA for your adult children. Children at this age (18-26) are just beginning to understand and manage their finances and establishing good habits can last a lifetime. Additionally, due to the nature of US healthcare you want to offer them every advantage they can get. Having a pile of cash to fall back on for medical care as they go through their 20’s can provide peace of mind as well as incentive to actually go and visit the doctor if something is wrong. It helps remove the money problem from medical decisions. In some ways, it is analogous to opening an IRA for them and contributing, but arguably, more practical.

Here are some additional advantages:

  • Emphasize importance of saving
  • Teach them the value of money and how to navigate US healthcare system
  • Encourage them to manage their finances wisely
  • Provide a financial safety net as they begin their career
  • Allow them to pay for healthcare as it arises
  • Contributions provide a tax deduction on Form 8889

That’s a lot of Filing Form 8889

One thing of note, is that you must file a Form 8889 for every HSA account that receives contributions or spends money, every year. That means that everyone with an HSA – you, your wife, any children – all need to fill out this tax form when filing you taxes each year. Being children, and new to taxes and HSA’s, they are prone to avoid or miss this requirement and incur financial penalty. Help them avoid this by explaining tax requirements; you can even see an article on how to file Form 8889.

Determine your Contribution Limit when “My Insurance Changed Last Year” – Line 3 on Form 8889

“I have a complicated situation, what is my HSA contribution limit for the year?”

I get this question quite a bit from readers, and it is a great question. At some point during the prior year, your plan / coverage / eligibility changed (possibly multiple times), and all the IRS says regarding the contribution limit is “$3,xxx for Single, $6,xxx for Family”. Not a lot of detail there. However, being good indentured servants taxpayers, we want to fill out our taxes correctly and avoid an audit, so let’s discuss how to determine your Health Savings Account contribution limit when you had insurance changes throughout the year.

The situations manifest themselves in a variety of ways:

  1. I began HSA eligible coverage this year, what is my contribution limit?
  2. I ended HSA eligible coverage this year, what is my contribution limit?
  3. I had gaps in my HSA eligible coverage this year, what is my contribution limit?
  4. My health insurance changed throughout the year, from single to family, what is my HSA contribution limit?

Spoiler Alert: You will see that situation #1 can employ the Last Month Rule / Testing Period, while the other 3 use a weighted average by month to determine total contribution limit. Read on.

#1: I began HSA eligible coverage this year, what is my contribution limit?

We know that there are single/family contribution limits for an HSA (2016: $3350/$6750), but what happens if you begin new HSA eligible insurance mid year? Do you get a partial contribution limit, a full contribution limit, or how do you calculate it? Well, the Last Month Rule, a part of the IRS tax guidelines, governs this. It basically says:

If you are covered by an HDHP on Dec 1st of a given year, you may contribute the maximum for that year.

However, there is a catch. In order for you not to take advantage of the system, if you take advantage of the Last Month Rule you are subject to the Testing Period. The Testing Period states:

If you contribute per the Last Month Rule and end your HDHP insurance within 1 year, you will have to pay tax on any excess contributions you were allowed to make and pay a 10% penalty.

Thus, you want to be very certain that you plan on maintaining HSA coverage for 1 full year if you take full advantage of the Last Month Rule. Otherwise, you will fail the Testing Period when you file next year’s taxes and the government, assuming you are taking advantage of the system, will penalize you for excess contributions (on a pro rata scale based on time you lost coverage). You can always choose to hedge your bet and contribute a fraction, say 50%, which would entail a 6 month Testing Period.


#2: I ended HSA eligible coverage this year, what is my contribution limit?

If you changed insurance or otherwise ended your HSA eligible insurance during the year, you can still contribute to your HSA for those months that you had HSA coverage. For example, if you had a family HSA and had coverage for 6 months, your contribution limit for 2016 would be $6,750 x 6/12 = $3,375. This means that you still reap the benefits of the HSA contribution, even though you have left the plan. In the prior example, if you had HSA insurance from January 1st – July 30th 2015 (6 months), you have up until tax day of the following year to contribute to your HSA. In this case, April 15th, 2016.

This contribution limit is verified by looking at the details of how Line 3 Limitation Chart and Worksheet determines your contribution limit on your HSA tax form, Form 8889:

This part determines your monthly contribution limit for 2015
HSA Form 8889 IRS Line 3 Limitation Chart 1
The second part performs the monthly average, summing and then dividing by 12
HSA Form 8889 IRS Line 3 Limitation Chart 2

Based on the above chart, you can see how any combination of insurance timing and coverage can lead to your yearly contribution limit.


#3: I had gaps in my HSA eligible coverage this year, what is my contribution limit?

No problem. Looking above at the Line 3 Limitation Chart Worksheet, just fill out your yearly contribution limit for those months you did have coverage. Other months when you didn’t have HSA coverage (say through a job, COBRA, other plan, etc.) can have a big fat 0. The zeroes don’t cause a problem, they just don’t add to your contribution limit for the year. For example, your data might look like this:

  • January – $3,350
  • February – $0
  • March – $0
  • April – $3,350
  • (etc.)

Just add them up, and divide by 12 to get your contribution limit.


#4: My health insurance changed throughout the year, from single to family, what is my HSA contribution limit?

Perhaps sometime during the year, your spouse was added onto your plan. You previously qualified for single ($3,350) coverage, but with the addition of your spouse (or kids) you qualified for family ($6,750) coverage. Then your spouse / kids left the plan. A few months of Family contribution limit, and then back to single.

No problem, just plug those numbers into the chart:

  • January – $3,350 <-single
  • February – $6,750 <-family
  • March – $6,750 <-family
  • April – $6,750 <-family
  • May – $6,750 <-single
  • (etc.)
  • Whatever your combination is, just plug the yearly contribution limit into the month, and then divide by 12.
