How to Form an LLC
in Idaho

Idaho charges a $100 Certificate of Organization filing fee for online submissions through the Idaho Secretary of State's SOSBiz portal (sosbiz.idaho.gov), or $120 for paper filings mailed to the Boise SOS office. Online is the standard path — same-day to 1 business-day processing with no paid expedited tier needed. Eleet AI charges $249 all-inclusive — that covers the $100 state fee, Certificate of Organization preparation, filing through SOSBiz, and first-year Idaho registered agent service. National services commonly advertise ID formation packages at $0–$199 then add the $100 state fee, a mandatory registered agent ($125–$299/yr), and various upsells, pushing the realistic first-year total to $300–$550+.

No — Idaho's annual report is completely FREE ($0) under Idaho Code § 30-25-211. This is genuinely unusual: Idaho is one of only six US states (Arizona, Idaho, Missouri, New Mexico, Ohio, South Carolina) with no recurring state-level LLC fee once you've filed the Certificate of Organization. The annual report itself is still mandatory — due by the end of your LLC's anniversary month each year through SOSBiz — but the filing fee is $0. Miss the deadline and you pay a $30 late fee; miss it for too long and your LLC is administratively dissolved (reinstatement is $30). For context on lifetime cost: an Idaho LLC filed in 2026 and kept in good standing through 2036 pays exactly $100 total to the state ($100 formation fee + ten $0 annual reports). The only US states that beat Idaho's lifetime cost are New Mexico ($50 one-time, no annual) and Missouri ($50 or $105 one-time, no annual). Idaho is tied-cheapest among states requiring an annual report filing.

Idaho has a 5.695% FLAT state income tax under Idaho Code § 63-3024, applied uniformly to both personal income and corporate income. That rate took effect January 1, 2024 under HB 40 (2024), further reducing the flat rate from 5.8% (2023) to 5.695% (2024+). Idaho moved from progressive to flat in 2022: HB 1 (2022) consolidated the 1.125%–6.5% progressive brackets into a 5.8% flat rate retroactive to January 1, 2022; HB 436 (2022) then dropped it to 5.8%; HB 40 (2024) dropped it to 5.695%. The trajectory is clearly downward — Idaho has cut its top marginal rate from 6.925% (2021) to 5.695% (2024+), a 17.8% reduction in three years. Pass-through LLC income flows to Idaho-resident members on Form 40 at the 5.695% flat rate (out-of-state members pay Idaho tax only on Idaho-source income). For comparison: 5.695% is comfortably below California 13.3% top / Oregon 9.9% top / Montana 5.9% top / Utah 4.55% flat / Wyoming 0% and Texas 0% / Nevada 0% / Washington 0% wage / Tennessee 0%. Idaho's combination of low flat rate + Affected Business Entity (ABE) federal SALT-cap workaround below makes it competitive with most non-zero-tax states.

Idaho's ABE (Affected Business Entity) election under Idaho Code § 63-3026B was enacted in 2021 under HB 317 to serve as a federal SALT-cap workaround for Idaho LLCs and S-Corps. Here's what it does: for federal tax years 2018–2025, the Tax Cuts and Jobs Act (TCJA) capped individual SALT (state and local tax) deductions at $10,000 per year. For profitable LLCs taxed as partnerships, high-income members lost the ability to fully deduct their Idaho income tax on federal Schedule A. The ABE election lets the LLC itself pay the 5.695% Idaho income tax at the ENTITY level (fully deductible at the federal level as a business expense, uncapped) while members receive a corresponding Idaho tax credit to avoid double taxation. For a multi-member Idaho LLC with $500,000 in annual pass-through income, ABE election can shift roughly $28,475 of Idaho tax from member Schedule A (capped at $10K combined with property tax) to entity Form 41S (fully deductible), saving somewhere between $5,000 and $10,000 in federal tax per year depending on member brackets. The ABE election is made annually on Idaho Form 41S when filing. IRS Notice 2020-75 confirmed the legitimacy of PTE-level workarounds. Eleet AI does not file Idaho tax returns but flags ABE as an election your CPA should evaluate at tax time.

Yes. Idaho imposes a 6% statewide sales tax under Idaho Code § 63-3619 on retail sales of tangible personal property and certain services. Most Idaho cities have NO local sales tax addition — the 6% rate is the total combined rate across most of the state. The exception: about 15 "resort cities" (population under 10,000, tourism-dependent) are authorized under Idaho Code § 50-1046 to levy a local-option sales tax by voter approval. Sun Valley and Ketchum charge 3% local (combined 9%), McCall charges 1.5% local (combined 7.5%), Stanley charges 3% local (combined 9%), Sandpoint charges 1% local (combined 7%), Driggs charges 1% local (combined 7%), Victor charges 1% local (combined 7%), and Lava Hot Springs + Donnelly + a handful of others charge 1% local (combined 7%). For a Boise, Meridian, Nampa, Caldwell, Idaho Falls, Pocatello, Twin Falls, Coeur d'Alene, or Lewiston business, the sales tax rate is exactly 6% with no municipal or county additions — among the simplest US sales-tax administrations (comparable to Connecticut 6.35% flat statewide, Mississippi 7% flat, Indiana 7% flat). LLCs with Idaho economic nexus register with the Idaho State Tax Commission through the Taxpayer Access Point (tax.idaho.gov/tap). Economic nexus threshold is $100,000 in Idaho-source sales per prior or current calendar year under Idaho Code § 63-3611.

Standard online processing through the Idaho Secretary of State's SOSBiz portal (sosbiz.idaho.gov) is same-day to 1 business day — among the fastest SOS turnarounds in the US, comparable to Wyoming's WyoBiz, New Mexico's Enterprise portal, Colorado's SOS online, and New Hampshire's QuickStart. Paper filings mailed to the Boise SOS office take 7–10 business days once received. Idaho does NOT offer a paid expedited tier because standard online processing is already fast enough that expediting is unnecessary. If a national formation service quotes you an Idaho "expedited" upcharge, that is a phantom fee the state does not recognize — you are paying the service, not the state. Eleet AI's standard Idaho filing uses SOSBiz online submission and typically delivers a filed Certificate of Organization within 1 business day.

Yes. Under Idaho Code § 30-21-401, every Idaho LLC must designate a registered agent with a physical Idaho street address — no P.O. boxes, no private mailbox services, no virtual-office-only addresses. The agent must be available during normal business hours to accept service of process and official state correspondence. Idaho uses standard "registered agent" terminology (not "resident agent" like Michigan/Maryland/Massachusetts, or "statutory agent" like Arizona/Ohio). You can serve as your own registered agent only if you personally have an Idaho street address. If you do not live in Idaho, you MUST use a commercial registered agent. Commercial registered agent services typically cost $100–$299 per year when purchased separately. Eleet AI includes first-year Idaho registered agent service free with every Idaho LLC formation, then $100/yr after — the same flat rate we charge in all 50 states.

This comparison comes up often because both states pitch low fees and business-friendly environments. Short answer: if you actually operate in Idaho (Boise tech, Treasure Valley growth, Magic Valley agriculture, Idaho Falls INL contracting, Coeur d'Alene tourism), form in Idaho — anything else creates a foreign-qualification headache. If you're a non-resident seeking anonymous holding-company structure with no Idaho nexus, form in Wyoming. Honest comparison: (1) Filing cost: ID $100 vs WY $100 — tied. (2) Annual report: ID $0 vs WY $60/yr (Idaho wins lifetime — WY is $700 over 10 years vs ID $100). (3) State income tax: ID 5.695% flat on pass-through to resident members vs WY 0% no state income tax. (4) Sales tax: ID 6% vs WY 4% state + up to 2% local. (5) Public anonymity: ID requires members/managers listed on Annual Report once per year vs WY allows fully anonymous public-record ownership under W.S. § 17-29-201. (6) Asset protection: both have charging-order exclusive remedy (ID § 30-25-503 for multi-member; WY § 17-29-503 is stronger for single-member LLCs per case law). (7) Series LLCs: ID NOT permitted vs WY permitted under W.S. § 17-29-1001. Bottom line: if you're an Idaho resident running an Idaho business, ID beats WY because foreign-qualifying a WY LLC back into Idaho costs $100/yr ID SOS + WY $60/yr = $160/yr recurring, defeats the point. If you're a non-resident holding Idaho real estate or intellectual property without active operations, WY anonymity + 0% income tax may outweigh Idaho's $0 annual-report advantage.

No. Idaho's Certificate of Organization under Idaho Code § 30-25-201 requires the organizer's name, signature, and mailing address, plus management structure designation (member-managed vs manager-managed) — and while members are not listed on the initial Certificate of Organization, the Annual Report filed each year in your LLC's anniversary month requires you to list either members (for member-managed LLCs) OR managers (for manager-managed LLCs), along with the principal business address and registered agent. That annual disclosure is free but public record through the SOSBiz database. Idaho's privacy profile is weaker than Wyoming (W.S. § 17-29-201 no member/manager disclosure), New Mexico (NMSA § 53-19-8 no member/manager disclosure), or Delaware (no member/manager disclosure on Certificate of Formation or annual franchise tax filing). Idaho's privacy profile is COMPARABLE TO most East Coast states — you will appear on a single annual public-record filing, not be anonymous. If public-record anonymity is a hard requirement, Wyoming or New Mexico is the right answer. Federal Beneficial Ownership Information (BOI) reporting with FinCEN applies to all US LLCs regardless of state-level anonymity.

Idaho does not legally require a written operating agreement — Idaho Code § 30-25-105 permits oral, implied, or written agreements — but you should absolutely have a written one. Without a written agreement, courts default to the statutory rules in the Idaho Uniform Limited Liability Company Act (Idaho Code Title 30 Chapter 25, effective July 1, 2015, RULLCA-based), and those defaults may not match how you actually want the LLC to operate (profit/loss allocations, distribution timing, member withdrawal rights, voting thresholds, buy-sell provisions, dissolution triggers). For single-member LLCs, a written operating agreement is particularly important: it strengthens the liability shield in litigation by demonstrating the LLC is a genuine separate entity with real governance, and it is often required by banks opening business accounts, title companies closing real-estate purchases, and lenders making business loans. Eleet AI offers an Idaho-specific operating agreement template for $99 that includes ID-statute-specific language on charging-order protection under Idaho Code § 30-25-503, member rights, capital contributions, distribution rights, and dissolution.
