My previous employer (March of 2019) has discovered that they were paying into my HSA account the amount for a family when I am a single person. This happened in 2017 and 2018, the amount they overpaid is 1800.00. They want me to pay them what they overpaid for these years. They are threatening to sue. Is that allowed? Can they go back that far?
Anyone can sue for any reason, so technically yes they can sue. The only thing that they might run up against is a statute of limitations, but that would be state dependent and you did not specify the state. Additionally, I would think that 2 years is within most statute of limitations.
I am no lawyer, and as such this is not legal advice. This is what I would do in your case:
I would say "okay, sue me". That will likely end the matter right there. $1800 is just not enough to make this worth while for most companies. It is probably a bullying tactic from a collection agency. How were you informed that they would sue you?
Lets say they do sue you. If this is not small claims court, you will be served with a complaint. For which you will have a limited time to respond. You can provide a response yourself (not hard) or file a motion for an extension (also not hard). Then make a decision from there. You can negotiate a settlement, find a lawyer, or represent yourself. However, I put this in the extremely unlikely category. LLCs, in Florida, have to be represented by outside council. How much will it cost them to go after you for 1800? Probably close to 100K and the judge may side with you out of sympathy.
Now they may possibly sue you in small claims court. I would still put this in about a 1% chance category, but they might. No biggie, learn about the process and follow it. Go to mediation, try to negotiate a settlement, whatever. Here you can represent yourself as you are on equal footing with lawyers. Small claims court is very forgiving provided you are respectful of the judge and his staff. These matters play out much like the "Judge Judy" type shows on daytime television.
If this amount was 18K, the same advice still applies. If it was 180K, it might change things a bit. While I understand 1,800 is probably a lot to you most healthy businesses should be putting their focus on other things. Perhaps correcting their HR procedures would be a good step, and there are probably 100 more profitable uses for their time.
The key here for you is to remain calm and do not give into fear.
