Stay compliant as a founder! Key steps include forming your entity before getting an EIN, securing federal and state licenses, and understanding tax obligations. Don't forget new Beneficial Ownership Information (BOI) reporting requirements effective January 1, 2024. State-specific rules are crucial: California LLCs face an $800 annual tax, New York LLCs have a publication requirement, and Delaware offers online annual report filing. Florida and Texas also highlight BOI reporting. For comprehensive guidance, consult official sources like the IRS, SBA, DOL, FTC, and state government sites.
