What affects the price
The final amount you pay for tax relief services depends on several moving parts. Your total debt balance is the biggest factor, as it dictates the complexity of the negotiation. Other elements include whether you have unfiled tax returns, the number of years you are behind, and if the IRS has already started active collection efforts like wage garnishment or liens. We evaluate your specific financial situation and history to determine the right path forward. Exact pricing confirmed free on the call.
