How Much Does an LLC Cost in Idaho?

Here’s exactly how much it costs to form an LLC in Idaho.

Idaho charges $100 to file your LLC online with the Secretary of State. That’s your all-in cost for a basic LLC formation if you handle everything yourself. Add registered agent service, name reservation, or expedited processing, and you’ll pay more.

Most business owners spend between $225-300 total in the first year when they use a formation service. That includes the state filing fee, registered agent service, and the convenience of having professionals handle the paperwork.

Idaho LLC Fee Breakdown

Here’s every fee you might encounter when forming your LLC in Idaho:

Required Filing Fee

The Idaho Secretary of State charges a mandatory filing fee for all new LLCs:

• Online filing: $100
• Paper filing: $120 (includes $20 manual processing fee)

Filing online saves you $20 and processes faster. There’s no reason to file on paper unless you absolutely cannot access the online system.

Expedited Processing Options

Idaho offers two expedited processing tiers if you need your LLC approved faster:

• Expedited service: +$40 (added to filing fee)
• Same-day service: +$100 (added to filing fee)

Standard processing typically takes 5-7 business days. Expedited service reduces that timeline, while same-day service gets your LLC approved within one business day.

Name Reservation (Optional)

You can reserve your desired LLC name before filing your formation documents:

• Online reservation: $20
• Paper reservation: $40
• Duration: 4 months

Name reservation is optional but recommended if you’re not ready to file immediately or want to secure a specific name. Idaho’s 4-month reservation period is longer than most states.

Annual Report Fee

Idaho charges $0 for annual reports. This makes Idaho one of the most LLC-friendly states for ongoing compliance costs.

Your annual report is due by the end of the month your LLC was formed. Even though it’s free, you must file it every year to keep your LLC in good standing.

Additional State Fees

Other fees you might encounter:

• Foreign LLC registration: $100
• Certificate of Good Standing: $10
• DBA/Assumed Name: $25
• Articles of Amendment: Varies by change type

Required Services and Hidden Costs

Registered Agent Service

Idaho requires every LLC to have a registered agent with a physical address in the state. You have two options:

• Serve as your own registered agent: Free
• Professional registered agent service: $125-200 per year

Self-service works if you have an Idaho address and will be available during business hours to receive legal documents. Professional service makes sense for out-of-state owners or anyone who values privacy and reliability.

The registered agent must have a street address in Idaho (no PO boxes allowed) and be available during normal business hours.

EIN (Federal Tax ID)

Your LLC will need an Employer Identification Number (EIN) for tax purposes and to open a business bank account. The IRS provides EINs completely free through their online application.

Never pay for EIN services. Third-party companies charge $50-300 for something you can get free directly from the IRS. It takes 10 minutes online.

Operating Agreement

Idaho doesn’t legally require an operating agreement, but you should have one anyway. It protects your LLC’s limited liability status and prevents disputes between members.

You can draft a basic operating agreement yourself using online templates (free) or hire an attorney ($500-1,500 for custom agreements).

First-Year Cost Comparison

DIY Formation

Handle everything yourself and pay only the minimum required fees:

• Idaho filing fee: $100
• Registered agent (self-service): $0
• EIN from IRS: $0
• Operating agreement (template): $0

Total DIY cost: $100

This works if you have an Idaho address, time to research requirements, and comfort with legal paperwork. You’ll handle all filing, compliance tracking, and document preparation yourself.

Formation Service

Use a professional service to handle filing and ongoing compliance:

• Idaho filing fee: $100
• Service fee: $0-39 (most providers offer free basic packages)
• Registered agent service: $125-200/year
• EIN filing: Usually included
• Operating agreement: Usually included

Total service cost: $225-339

Formation services handle the paperwork, provide registered agent service, file for your EIN, and include compliance reminders. The extra $125-239 covers professional handling and ongoing support.

Why Use a Formation Service?

Time Savings

Researching Idaho’s requirements, completing forms, and tracking compliance deadlines takes 4-6 hours minimum. Formation services handle everything in minutes while you focus on your business.

Accuracy and Compliance

Mistakes on your Articles of Organization can delay approval or create legal problems later. Professional services know Idaho’s specific requirements and file correctly the first time.

Included Registered Agent

Most formation services include one year of registered agent service. This alone costs $125-200 annually, making the service fee essentially free.

Ongoing Support

Formation services send compliance reminders for annual reports and other deadlines. They also provide customer support when you have questions about your LLC.

After Formation: Additional Business Costs

Business Banking

Your LLC needs a separate business bank account to maintain limited liability protection. Mixing personal and business finances can pierce your LLC’s corporate veil, exposing your personal assets to business debts.

Look for business checking accounts with no monthly fees, unlimited transactions, and convenient online banking. Many banks waive fees for new LLCs during the first few months.

Business Insurance

Even with LLC protection, you should consider business insurance for professional liability, general liability, and property coverage. Insurance costs vary widely based on your industry and coverage needs.

Basic general liability insurance typically costs $300-800 annually for service businesses, while product-based businesses may pay more.

Accounting Software

Proper bookkeeping is essential for tax compliance and business management. Accounting software helps track income, expenses, and generates reports for tax filing.

Basic plans start around $15-25 monthly and include invoicing, expense tracking, and basic reporting features.

Idaho LLC Tax Considerations

Understanding tax implications helps you budget for ongoing LLC costs:

State Income Tax

Idaho charges a flat 5.8% income tax on LLC profits. LLCs are pass-through entities, so you’ll pay this tax on your personal return.

Federal Taxes

Single-member LLCs report income on Schedule C of their personal tax return. Multi-member LLCs file Form 1065 and issue K-1s to members.

Consider making an S-Corp election if your LLC generates significant profit, as it can reduce self-employment taxes.
