Idaho LLC formation costs

Idaho offers one of the most affordable LLC formation options in the United States, with a $100 online filing fee and no annual report charges. This combination of low upfront costs and minimal ongoing expenses makes Idaho particularly attractive for entrepreneurs seeking predictable compliance costs.

Beyond the state filing fee, you'll need to consider registered agent services, operating agreements, and optional professional assistance. Idaho's transparent fee structure eliminates surprise charges common in other states, allowing you to budget accurately for both formation and long-term compliance.

Required Idaho LLC formation costs

Every Idaho LLC faces three essential expenses before beginning operations:

Required Cost Amount Notes
State filing fee $100 online / $120 paper Required for all LLCs; paper filing includes $20 manual processing fee
Registered agent $0 (self) / $125-$400/year Must maintain an Idaho physical address; professional service provides privacy
Operating Agreement $0 (DIY) - $1,000+ Professional drafting recommended for multi-member LLCs

The $20 difference between online and paper filing reflects Idaho's preference for digital submissions, which also process faster and provide immediate confirmation.

Optional formation costs

Beyond Idaho's mandatory $100-$120 filing fee, several optional services can streamline your formation process or provide valuable legal protections, though none are required by state law.

1. Professional services

Professional services offer expertise that becomes particularly valuable for complex business structures. Attorney fees for comprehensive formation assistance typically range from $1,500 to $5,000, including custom operating agreements and ongoing compliance guidance. Accountant consultation for initial tax planning runs $100-$500 and often prevents costly mistakes once you're operational. 

Business formation services provide a middle ground, with basic packages starting around $0 in service fees (plus the state fee) while premium offerings include registered agent services and compliance tracking.

2. Additional filings

Additional filings address specific needs that may arise during formation. For example:

  • Name reservation costs $20 and protects your chosen LLC name for 120 days while you finalize funding or partnerships. 
  • Expedited processing adds $40 for next-day service or $100 for same-day processing when timing is critical. 
  • DBA registration costs $25 if you plan to operate under a name different from your LLC's registered name.
  • Certified copies cost $10 plus $0.25 per additional page when banks or lenders need official verification of your LLC's existence
  • Getting an EIN is free from the IRS
  • Local licensing costs vary significantly by city and industry, typically $10-$500 for initial permits

Ongoing annual costs

Idaho's ongoing compliance costs remain refreshingly simple compared to most states, with the biggest advantage being completely free annual report filing. However, the state still requires you to file, even though it’s free. 

Your recurring expenses depend primarily on business licenses and professional services rather than state-mandated fees.

  • Idaho annual report: Due by the end of your LLC's anniversary month ($0 online—completely free, making Idaho exceptional among U.S. states)
  • Idaho franchise tax/annual fee: No franchise tax—Idaho doesn't impose additional entity-level taxation on LLCs, with profits flowing directly to personal tax returns
  • Registered agent fees: $35–$49 annually if using a professional service; free if serving as your own agent
  • Local business licenses: Annual renewals vary by municipality and industry, typically $10-$500 depending on business type and location
  • Professional services: Accounting and legal support costs $300-$900 annually for tax preparation and compliance guidance as needed
