Step-by-Step Compliance Guide

  2. Next, fulfill Federal income and self-employment tax obligations for your LLC, with potential costs varying and a one-time requirement.
  3. Ensure compliance with the Federal Trade Commission (FTC) regarding Truth-in-Advertising and Consumer Protection, which carries no initial fee and is a one-time requirement.
  4. Adhere to the Americans with Disabilities Act (ADA) compliance standards for customers, as determined by the Department of Justice, with costs varying and a one-time requirement.
  5. Display the OSHA Job Safety & Health Poster from the U.S. Department of Labor, which has varying costs and requires annual renewal.
  6. Maintain thorough record retention for tax and employment records, as required by various agencies like the IRS and OSHA, with a one-time requirement.
  7. File your Federal Annual Income Tax Return (IRS Form 1065 or 1120) annually with the IRS, with no associated fee.

Common Mistakes to Avoid

  • Assuming a single federal license covers all tree service operations ignores the need for specific state and local permits.
  • Overlooking annual requirements, like the OSHA poster renewal, can lead to penalties.
  • Failing to properly categorize workers as employees or independent contractors can result in tax issues.
  • Neglecting to comply with FTC advertising rules can lead to legal action and fines.
  • Believing that simply forming an LLC automatically handles all tax obligations is a common error.
