Verdict: Idaho wins for most businesses
For most Idaho-based businesses, forming locally in Idaho is the smarter choice. You avoid paying fees in two states and managing compliance in both. Delaware only makes sense if your business genuinely operates there or your investors require a Delaware entity, and even then the total costs deserve a hard look.

Compare LLC Costs: Idaho vs Delaware
Idaho
Delaware
Costs include every mandatory state charge: the filing fee, the report fee (annualised where a state files biennially), any state entity-level tax shown in its own row above, a one-time publication cost where a state requires publication, and any one-time registration charge a state requires before the LLC may trade. Annualising makes the 1, 3 and 5 year rows a cost of ownership rather than a payment schedule: a biennial state charges its whole report fee in the years it falls due and nothing in between. Entity-level taxes that only apply after a corporate election, or above an owner or income threshold, are excluded and flagged on the state's own cost page. New York's publication cost is carried at a $250 floor, roughly $200 of newspaper cost in a low-cost county plus the $50 Certificate of Publication fee. No county-clerk-designated New York City newspaper publishes a rate card, so the four-figure NYC estimates in wide circulation cannot be traced to a primary source and are not asserted here; budget for materially more than the floor if you file in a NYC county. Montana's annual report is free when filed by April 15 and $35 after, a waiver the Secretary of State applies at its discretion. Every fee was verified against the state's own fee schedule, statute, or revenue authority on 29 July 2026. Excludes registered agent and legal fees.

Filing Fees & Formation Costs
Idaho charges $100 to form an LLC, while Delaware charges $110. Idaho is $10 cheaper upfront. The cost that usually gets overlooked: if you form in Delaware but operate in Idaho, you must also register as a foreign LLC in Idaho (a $100 filing) and maintain a registered agent in Delaware (typically around $150 per year). That puts the realistic first-year cost of the Delaware route at roughly $360, versus $100 for simply forming in Idaho. Speed isn't a basis for choosing between them: neither Idaho nor Delaware publishes a standard processing time, so any figure comparing the two is guesswork.
Taxes: Idaho vs Delaware
Both Idaho and Delaware levy a personal income tax on pass-through business income, and your LLC's profits will be taxed where you live and operate. Forming in Delaware doesn't change what an Idaho-based owner pays. Idaho levies a personal income tax (flat 5.695%). Delaware LLCs owe a flat $400 annual LLC tax (no report required).
Privacy & Asset Protection
Delaware allows anonymous LLC formation. Member and manager names don't appear on routine public filings. Delaware's Certificate of Formation requires no member or manager names, and LLCs file no annual report, so ownership never appears on a public filing. Idaho doesn't offer that same privacy. Idaho's annual report requires at least one member or manager (a 'governor'), and filings are public. Both states provide charging-order protection for LLC members, and for most small businesses the practical difference in asset protection between the two is minimal. One important caveat: if you register your Delaware LLC as a foreign LLC in Idaho, that Idaho registration is itself a public record, which can undercut much of the privacy benefit for a business that operates in Idaho.
Annual Maintenance Costs
Idaho LLCs file a free annual report (due in the anniversary month), and Delaware LLCs file no annual report at all. If you form in Delaware while operating in Idaho, you maintain filings in both states, Delaware asks for no report, but Idaho still wants its equivalent for your foreign registration, and pay a Delaware registered agent roughly $150 per year. Counting report fees, the agent and any entity-level tax, that brings the Delaware route to roughly $550 a year, versus about $0 to keep a domestic Idaho LLC in good standing. The tax inside those totals: Delaware LLCs owe a flat $400 annual LLC tax (no report required).
When Delaware Actually Makes Sense
Forming in Delaware makes sense in a few specific situations: you need anonymous ownership. Idaho puts owner or manager information on public filings and Delaware doesn't (usually via a holding company, since operating in Idaho still requires a public foreign registration there), you're raising venture capital or institutional investment. Many investors specifically prefer or require Delaware entities, your business genuinely operates in Delaware, with a real office, employees, or property there, or you're relocating to Delaware in the near future. For a typical small business based in Idaho, none of these usually apply. Registering a Delaware LLC to do business back home means $100 in Idaho foreign-registration fees, on top of Delaware's $110 formation fee, while Idaho's own annual report stays free to file and is due in the anniversary month. When in doubt, form where you actually do business.
