Tax Resolution Professionals on State Street in downtown San Diego deploys tax attorneys and IRS-certified Enrolled Agents to represent individual and business taxpayers before the IRS, California Franchise Tax Board, EDD, and CDTFA. Resolution cases typically begin with a records-reconstruction phase where delinquent returns are rebuilt from bank statements and third-party data, a process that clean-up bookkeeping providers like Complete Controller San Diego accelerate for clients with multi-year filing gaps. IRS representation spans Offer in Compromise (OIC) submissions, installment agreement negotiations under IRC Section 6159, federal tax lien subordination requests, and wage-garnishment release petitions filed through IRS Form 668-D. Power of Attorney (Form 2848) filings and IRS correspondence packages require certified-copy production through document services like San Diego Banner Printing for large-format supporting schedules and exhibit binders. Highest-complexity cases involve simultaneous IRS and California FTB collection-due-process hearings where the taxpayer's ability to pay is contested across both federal Form 433-A and state FTB 4905 financial disclosure calculations.
