Beware of tax relief companies claiming to be able to help you with back taxes. Often, these companies request an upfront fee (sometimes thousands of dollars) in exchange for them applying for an IRS hardship program that you may not even qualify for. Only the IRS can determine your eligibility and tell you if you should apply. Often, the companies donâ€™t settle the debt or file the proper paperwork. Instead, contact the IRS Taxpayer Advocate Service for help. Remember: only and Enrolled Agent, CPA, or tax attorney has the authority to represent you before the IRS.
