Annual compliance + bookkeeping + tax bundle

I used parallel searches and targeted scraping to gather authoritative federal and state-level guidance on annual compliance, bookkeeping, and tax requirements relevant to US LLC owners and business founders. Sources include IRS small business filing guidance, FinCEN BOI rules, and state pages for Delaware, California, and Texas (franchise taxes and annual/statement of information requirements). Key findings: 1) Federal tax filing rules by entity type (Form 1040 Schedule C, 1065, 1120/1120-S), estimated tax obligations, payroll filing requirements, and common deadlines (March 15 for partnerships/S Corps; April 15 for C Corps and sole proprietors). 2) BOI reporting requirements under FinCEN (who must file, deadlines, updates). 3) State-specific examples: Delaware franchise tax calculation and payment requirements; California annual Statement of Information and $800 minimum franchise tax; Texas franchise tax thresholds and public information report/filing. 4) Bookkeeping best practices: regular reconciliations, separation of personal/business accounts, recommended software (QuickBooks, Xero, Wave), maintaining chart of accounts, monthly close, year-end preparation, and retention timelines (3–7 years). 5) Practical compliance bundle components: registered agent, annual report filing, bookkeeping (monthly/quarterly), payroll tax filings, federal/state tax return preparation, estimated tax management, BOI filing assistance, and pricing models (flat subscription, tiered packages, hourly for one-offs). 6) Penalties and consequences: late fees, interest, administrative dissolution, and significant fines for failure to file BOI or Form 5472. I included verbatim excerpts from each source below to support these findings.
