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

Compare LLC Costs: Delaware vs Idaho
Delaware
Idaho
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
Delaware charges $110 to form an LLC, while Idaho charges $100. Idaho is $10 cheaper upfront. The cost that usually gets overlooked: if you form in Idaho but operate in Delaware, you must also register as a foreign LLC in Delaware (a $200 filing) and maintain a registered agent in Idaho (typically around $150 per year). That puts the realistic first-year cost of the Idaho route at roughly $450, versus $110 for simply forming in Delaware. Speed isn't a basis for choosing between them: neither Delaware nor Idaho publishes a standard processing time, so any figure comparing the two is guesswork.
Taxes: Delaware vs Idaho
Both Delaware and Idaho 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 Idaho doesn't change what a Delaware-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, your home state, actually offers more formation privacy than Idaho: Delaware allows anonymous LLC formation, while Idaho requires owner or manager information on public filings. 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. From a privacy standpoint there's no reason for a Delaware-based business to form in Idaho.
Annual Maintenance Costs
Delaware LLCs file no annual report at all, and Idaho LLCs file a free annual report (due in the anniversary month). If you form in Idaho while operating in Delaware, you maintain filings in both states, Idaho's report, though Delaware asks for nothing on the foreign-registration side, and pay an Idaho registered agent roughly $150 per year. Counting report fees, the agent and any entity-level tax, that brings the Idaho route to roughly $150 a year, versus about $400 to keep a domestic Delaware LLC in good standing. The tax inside those totals: Delaware LLCs owe a flat $400 annual LLC tax (no report required).
When Idaho Actually Makes Sense
Forming in Idaho makes sense in a few specific situations: your business genuinely operates in Idaho, with a real office, employees, or property there, or you're relocating to Idaho in the near future. For a typical small business based in Delaware, none of these usually apply. Registering an Idaho LLC to do business back home means $200 in Delaware foreign-registration fees, on top of Idaho's $100 formation fee, while Delaware itself never asks for an annual report at all. Delaware already allows anonymous formation, so the privacy argument for Idaho doesn't apply to a Delaware-based owner. Trading Delaware's no-annual-report status for Idaho's filing calendar is a step backwards for most owners. When in doubt, form where you actually do business.
