The IRS has no time limit for assessing taxes when you never filed returns and typically requires the most recent six years for compliance. Federal filings trigger state tax agency reviews within 60-90 days, so coordinate both simultaneously. Separate your business obligations from personal returns to prioritize critical liabilities and prevent Trust Fund Recovery Penalty assessments against business owners personally.
Identify notices requiring 30-day responses like CP504, Letter 1058, or Notice of Deficiency to prevent automatic assessments. Document reasonable cause for late filing such as medical emergencies, natural disasters, or death in family to support penalty abatement requests. We file all required returns with complete deductions, prepare reasonable cause statements, negotiate penalty relief, and arrange payment plans that protect your wages and bank accounts from IRS levies.
