IRS problems create overwhelming stress for taxpayers who fall behind on tax obligations. The federal government imposes significant interest rates and accumulating penalties on unpaid taxes, quickly escalating financial burdens. Beyond monetary penalties, the IRS can garnish wages, seize bank accounts, and place liens on property, making professional assistance essential.
Specialized tax resolution professionals focus specifically on resolving complex tax issues like back taxes and IRS disputes. Unlike general tax preparers, these certified specialists possess in-depth tax code knowledge and can represent clients directly before the IRS. They work to secure settlements for less than full liability or negotiate manageable payment plans, alleviating immediate pressure and guiding clients toward sustainable resolutions.
James is a CPA and also a Certified Tax Resolution Specialist ® (CTRS). The CTRS represents a pinnacle of expertise and dedication in the field of tax problem resolution. This designation is awarded to tax professionals specializing in tax problem resolution who meet educational, proven experience, and examination standards set by the American Society of Tax Problem Solvers.
Candidates must demonstrate advanced tax law knowledge, complete specialized training, and pass a comprehensive exam. Working with a Certified Tax Resolution Specialist assures you that your tax professional is uniquely qualified to handle your tax problems with negotiation skills and collection resolution strategies.
He frequently speaks on tax representation topics at numerous organizations. His articles have appeared in AP News, KTVN CBS, Fox 21, NBC 21WFMJ, WBOC-TV CBS, The Business Journals, and many more news publications.
James serves on the board of directors for a variety of local and national non-profits and volunteers to give back to his community. He has been accepted into the L.A. Biz Leadership Trust, an invitation-only network of influential business leaders in the greater Los Angeles area. He has also served as the President of the KACPA Society. He holds memberships in the Association of International CPAs, National Society of Accountants, KA Chamber of Commerce, and Korean Real Estate Brokers Association of Southern California.
