EIN registration with the IRS is free. This calculator provides a comprehensive first-year and multi-year cost projection for forming and maintaining an LLC in Idaho. Idaho charges no fee for the annual report, but filing it is mandatory and missing it leads to administrative dissolution. Formation is $100 online or $120 on paper.

Example Calculation

Let's calculate the cost to form and maintain an LLC in Idaho.

Forming a single-member LLC in Idaho: state filing fee $100, registered agent service (~$125/year), EIN from IRS (free), and a DIY operating agreement (free, or $500-$1,500 with an attorney). Idaho's annual report/franchise tax is $0 — no recurring state fee.

Result: Year 1 total: approximately $225 (plus any optional attorney fees). Ongoing annual cost: approximately $125/year. Nationally, filing fees range from $35 (Montana) to $500 (Massachusetts) and recurring state costs range from $0 (several states) to $800/year (California) — so Idaho's cost may be far cheaper, or more expensive, than forming elsewhere. Don't form in Delaware or Wyoming just for their reputation — you'll still need to register as a foreign LLC at home and pay both states.

How much does it cost to form an LLC in Idaho?
