IRS has millions that owe taxes and prioritizes what they spend the time going after.
Trust Fund taxes (where a business takes money from your paycheck each payday) is big priority.
As long as they get some money every year, it is not getting a lot of attention. It is not however going away.
I talked to fellow worker who was an IRS Collections Officer and said due to getting yearly payments and low balance it is not getting much attention due to others having higher priority.
I would order a detailed IRS transcript or call the IRS if you want to get this taken care of, as interest keeps accruing on the unpaid balance.
