No, the IRS doesn't have to leave you a livable wage.
The IRS must only follow a table that determines how much money it must leave for you to live on each month.
The amount that it must leave is small, and there are just 4 factors that play into the determination:
- Whether you are married
- The number of exemptions you should claim
- Whether you are older than 65
- Whether you are blind
If you are married filing a joint return and you get paid on a monthly basis, and take 2 exemptions, the IRS will leave you 1666.67 to live on.
It won't matter if you make $2000.00 per month or $20,000.00 per month, the IRS will leave you 1666.67 to live on each month until the debt is paid off or you do something else to deal with the debt like:
a. Arrange a payment plan or non-collectible status situation based on another set of budget figures.
b. Propose an Offer in Compromise
c. File a Bankruptcy
Obviously the IRS doesn't use the IRS Publication 1494 to collect the debt. It uses it to force you to do something about the debt.
