Hi from Just Answer. I'mCustomer I can assist since the last expert opted out.
The best thing to do is make sure the returns were received by IRS, and taxes assessed. You used to be able to get your transcripts immediately, at www.irs.gov. Now, you can still ask for them online, but they are mailed to you.
Then, you confirm the CSED (collection statute expiration date) to see how long IRS has to collect.
You might also confirm who is the taxpayer who owes the 941 taxes (you or your business). If you had a corporation, it owes the taxes, and you might have been personally charged a trust fund recovery penalty (TFRP). If you were self employed, then the taxes are all yours.
If the transcript shows the 941 forms filed, and taxes assessed, that you consider your options:
1. Let the collection statute expire, likely in 2019.
2. Consider your current income and expenses, to see if you are a candidate for uncollectible status ("53 or "530"" in IRS code). If so, IRS will not pursue collection, and the taxes might expire.
3. An installment agreement might be needed, based on your ability to pay, and the payments could get you to the CSED, when the taxes would no longer be collectible
4. You might negotiate a settlement with IRS via an Offer in Compromise.
This is not a scenario that you should undertake on your own. An experienced tax pro will be worth their fee if IRS does indeed want to pursue collection.
