IRS problems have many causes, but usually just one result – you have to pay what you owe, or settle for a negotiated amount. Most start with unfiled or incorrect tax returns or back taxes that haven’t been paid. For business owners, it’s often payroll tax problems. These may have resulted in a tax lien, wage garnishment or bank levies, and now you’re facing an audit and possibly penalties and interest.
