What an LLC costs every year in Idaho

Annual Report

By the last day of the month the LLC was formed, each year, starting one year after formation If the report is not filed, the Secretary of State can administratively dissolve the LLC 60 days after sending notice.

State tax on the LLC

Idaho charges no franchise tax and no annual report fee on LLCs. An LLC taxed as a partnership that does business in Idaho files Form 65 with the State Tax Commission by April 15. It pays no entity-level income tax, but it must withhold tax for nonresident individual members with $1,000 or more of Idaho income, or pay it for them on a composite return. A seller's permit, needed to sell taxable goods, is free.

How long Idaho takes

The Secretary of State currently lists about 3 to 5 days. Expedited service costs $40 for evidence of filing within eight working hours, or $100 for same-day service if the filing arrives before 1 p.m. Mountain time.

What is different about Idaho

• There is no annual report fee, but a missed report is grounds for administrative dissolution.
• Paper filings cost $20 more than online ones, and paper annual report forms are available only on request.
• An administratively dissolved LLC has up to 10 years to apply for reinstatement, for $30.

What else you pay in year one

Registered agent. Free if you serve as your own agent at a Idaho street address; a service charges an annual fee if you would rather keep your address off the public record.
EIN. Free from the IRS. Anyone charging for an EIN alone is charging for the form.
Annual report or franchise tax. Most states ask for a yearly report and some charge a fee or tax with it; the amount and deadline are set by Idaho. Check the Secretary of State page before you file so the first renewal is not a surprise.
Licences and permits. City and county rules depend on what the business does, not on the entity type.

Questions founders ask about Idaho

How much does an LLC cost per year in Idaho?: Nothing in state filing fees, because the annual report is free. Ongoing costs are a registered agent, if you use a service, and any taxes the business owes.
How much does it cost to form an LLC in Idaho?: $100 online through SOSbiz, or $120 on paper because of the $20 manual processing fee. Expedited service adds $40, or $100 for same-day.
What happens if I miss my Idaho LLC annual report?: The Secretary of State can start administrative dissolution, and the LLC has 60 days after the notice to file. A dissolved LLC can apply for reinstatement within 10 years for $30.
How much does it cost to start an LLC in Idaho?: The Idaho state filing fee for an LLC is $100, paid once when you file the formation document. That is right at the national median: 18 of 51 jurisdictions charge less, and the national median is $100. Registered agent service, expedited processing and any EazeAccounts package are separate.
Do I need a registered agent in Idaho?: Yes. Every state requires an LLC or corporation to name a registered agent with a physical street address in Idaho who is available during business hours to receive legal and official mail. You can be your own agent if you live in the state, or use a service.
What is the difference between the state fee and the EazeAccounts fee?: The state fee goes to the Idaho Secretary of State and is the same whoever files for you. The EazeAccounts formation package covers preparing and filing the documents, the EIN, the operating agreement or bylaws, and setting your books up from day one. You always see both amounts before you pay.
Is the state filing fee refundable if my filing is rejected?: Generally no. States keep the fee even when a filing is rejected for a name conflict or a missing detail, which is why the name check and document review happen before anything is submitted.
