n Idaho LLC costs $100 to form online and $0 a year to keep current. Those are the two numbers that matter in January 2024, and together they make Idaho one of the cheaper compliance regimes in the country.

This is a guide for someone forming in Idaho this quarter. It will not explain why Idaho has become a formation state people talk about, because if you are here you have probably already noticed.

The mechanics

You file a Certificate of Organization with the Idaho Secretary of State. The online portal is called SOSbiz, and it is the path the state would prefer you take. Filing through SOSbiz costs $100. Filing the same paperwork on paper costs $120, a $20 premium that pays for somebody in Boise to retype what you could have typed yourself. The Secretary of State publishes the fee schedule at sos.idaho.gov and has held these numbers steady through the current year.

The certificate itself is short. Idaho Code Title 30, Chapter 25 (the Idaho Uniform Limited Liability Company Act) sets the required contents: the name of the LLC, the street and mailing address of the principal office, the name and street address of the registered agent, the name and address of each organizer, and whether the LLC is member-managed or manager-managed. If you use SOSbiz the form walks you through each field, validates the name against the state's registry, and lets you pay by card.

Processing is typically a few business days for online filings and noticeably longer for paper. Idaho does not publish the tiered expedite menu that Delaware does. If you need a same-week formation, file online and check the state's processing-time banner before you submit.

You will need an EIN, which the IRS issues from the time it takes to complete Form SS-4 online. You will need an operating agreement, which the Act expects but does not require you to file. And you will need to pick a federal tax classification: disregarded (single-member default), partnership (multi-member default), S-corp, or C-corp. Most founders let the default ride through the first full year and revisit only when revenue arrives.

Maintenance is where Idaho gets quietly interesting

Idaho requires an annual report from every LLC and corporation on the rolls. The fee for that report is $0. The state asks you to confirm the principal office, the registered agent, and the governors or members; it does not ask you to send money. The report is due by the end of the anniversary month of formation, and the Secretary of State will send a reminder to the registered agent's email on file.

Miss the deadline and the state does not charge a late fee. It simply administratively dissolves the entity after a grace period that currently runs about two months past due. Reinstatement costs $30 through SOSbiz, assuming you act within the statutory window. The practical effect: an Idaho LLC that is used and attended costs $100 total over its first two years, and a neglected one costs a few more dollars and a reinstatement filing to revive.

Compare Delaware, which charges $90 to form an LLC and then $300 a year, every year, forever, with a $200 penalty plus 1.5% monthly interest if you miss June 1. Over a five-year hold, a Delaware LLC bills out at about $1,590 in state fees assuming nothing goes wrong. An Idaho LLC over the same five years bills out at $100. The Delaware premium buys you the Court of Chancery and a case-law library investors ask for by name. For a holding entity running cash-flow operations in the Mountain West, it buys very little.

The corporate rate and why accountants are paying attention

Idaho's corporate income tax is a flat 5.8% of taxable income, one of the headline numbers in House Bill 436 signed in February 2022. The rate sits in Idaho Code § 63-3025. Before HB 436 the state had a graduated structure with a top rate of 6.5%; the bill collapsed both the individual and corporate brackets to single flat rates and has held at 5.8% through tax year 2023 and into 2024.

For owners of pass-through entities (S-corps, partnerships, and multi-member LLCs) the relevant provision is the pass-through entity tax election at Idaho Code § 63-3022L, added by House Bill 317 in 2021 and first available for tax year 2021. Electing PTEs pay Idaho income tax at the entity level, which preserves the federal deduction the TCJA's $10,000 SALT cap otherwise cuts off for itemizing owners. The entity-level rate matches the individual flat rate, and the owners take a credit on their Idaho returns for their share of the PTE tax paid. The election is annual and irrevocable for the year once made; miss the deadline and you are back to default conduit treatment.

This is not tax advice for your particular situation. It is the shape of the rules. A founder forming in Idaho in 2024 with Idaho-source income and itemized federal deductions will usually want the PTE election on the table from day one; a founder with no SALT-cap pressure or a C-corp structure will not.

The registered-agent market, briefly

Every Idaho LLC needs a registered agent with a physical Idaho address. Idaho Code § 30-21-404 requires the agent to be an individual resident of Idaho or a business entity authorized to transact business here. Commercial registered agents serving Idaho run roughly $50 to $150 a year at the commodity tier and up to several hundred at the full-service tier.

If you live in Idaho and own the address where mail actually arrives, you can be your own agent. Many single-member founders do. The tradeoff is that your residential address becomes public record on the state's business search, and that service of process will be delivered to you personally at home. For most operating businesses that is fine. For a founder with a public profile or a lawsuit exposure they would rather not have delivered at the front door, the commercial agent is worth the $100.

Who Idaho actually makes sense for in 2024

Three kinds of entities belong in Idaho right now.

The first is any operating business with an Idaho nexus: a contractor, a clinic, a retail location, an AirBnB portfolio physically located in the state. Foreign-qualifying a Delaware or Wyoming LLC into Idaho costs $100 for the Certificate of Authority plus the ongoing registered-agent fees in two states, and buys you nothing a domestic Idaho LLC does not already have.

The second is a holding entity for Idaho real estate. Idaho's series-LLC provisions sit in Idaho Code § 30-25-201(2), and the zero-dollar annual report means a portfolio of single-property LLCs does not generate a recurring fee burden the way it would in a state that charges per entity each year.

The third is any business whose owners live in Idaho and plan to keep living there. The PTE election under § 63-3022L works cleanest when the owners are Idaho residents filing Idaho returns; non-resident owners can still benefit, but the state tax return coordination gets more complicated and the SALT-cap math depends on the owner's home state rules.

Who Idaho does not make sense for: a venture-backed startup expecting institutional money inside eighteen months. Investors still want Delaware, and converting an Idaho LLC to a Delaware C-corp later costs several thousand dollars in legal and accounting work and leaves a visible scar in the cap table. Start in Delaware if that is the direction of travel.

For everyone else forming this quarter with an Idaho tie, the math is close to decided. File the Certificate of Organization through SOSbiz, pay the $100, get the EIN the same afternoon, and put a calendar reminder for the first anniversary-month annual report. The whole exercise costs less than a dinner and holds up until the business changes shape enough to need a different answer.
