IRS Collections

The firm handles all types of collections matters with the IRS. The IRS Collections department often takes a tough approach when dealing with a liability owed to the government, such as a levy against bank accounts, wage garnishments, or placing tax liens on assets. This can be a very stressful situation for people, however we work with clients to relieve that stress and develop the best strategy for dealing with unpaid tax liabilities. RJS LAW can help with IRS tax debt relief through an Offer in Compromise (OIC), IRS payment plan, placing accounts in non-collectible status, penalty abatements, innocent spouse relief, lien removal, and levy release.
