IRS compliance services

Research complete. I collected authoritative, up-to-date guidance (IRS, FinCEN and related resources) covering IRS compliance services for US business owners and LLC founders, including entity classification, EINs, federal employment tax obligations (forms, deposit schedules, e-file), filing deadlines, recordkeeping, notices/audits/appeals, penalty relief, offers-in-compromise and installment agreements, and international reporting (FBAR/FATCA). I also captured practical action steps and recommendations for services tax professionals offer (bookkeeping, payroll, tax representation, penalty relief, voluntary disclosure/streamlined filings). I’m ready to draft the comprehensive blog post and newsletter content (including state-specific guidance where you specify states).
