Can a wage levy be stopped by agreeing to a voluntary payment plan?

The answer depends on who is levying the wages.  The South Carolina Department of Revenue will not release a levy after it has attached until the levy is paid in full.   They take 25% of the employee’s gross (before taxes) income.  Many times they will agree to cut the amount in half if the levy is causing a hardship.  The IRS will release a wage levy if the employee can agree to a voluntary Installment Agreement.  Depending on how much he owes in back taxes, this might be a Streamline Agreement, where he does not give them any of his financial data, or a regular Installment Agreement.  In this case the amount of the monthly payment depends on his current financial situation and is calculated based on that.
