Delaware vs Idaho LLC: fees, taxes, and which to pick
Data last updated: Apr 21, 2026Delaware charges $110 to form an LLC; Idaho charges $100. Day-one sticker price is only part of the story, since most of the real cost comes from the annual obligations that stack up each year you keep the LLC open.
Over a rolling three-year window, Idaho runs about $910 less in total state fees than Delaware. Whether that gap matters depends on whether you actually operate in one of these states or are weighing a non-resident filing.
Delaware imposes an entity-level annual tax on every LLC ($300 minimum). Idaho does not. For pass-through LLCs that would otherwise owe nothing at the state level, that minimum is the deciding line.
On speed, Idaho typically clears standard online filings faster than Delaware. Both states offer expedited tiers at an additional cost for filers on tight timelines.
For most small operators the choice is not really between these two states at all. It is between forming where the business actually operates and trying to route through a non-resident filing. The data below shows what each option actually costs.
Key differences at a glance
- Idaho costs $10 less to form ($100 vs $110).
- Idaho is $300 per year cheaper to maintain ($100 vs $400).
- Delaware imposes an entity-level franchise or LLC tax that applies to pass-through LLCs. Idaho does not.
- Delaware has no annual report filing at all. Idaho requires an annual (or biennial) report every reporting period.

Three-year cost, side by side
Rough estimate of the state-facing cost to form and keep an LLC through three years. Both totals include a $100 per year registered-agent estimate.
Running total includes the one-time filing fee and annual ongoing costs (report fee or franchise tax plus a $100/year registered agent estimate).
What it costs under your specific situation
The table below runs the same LLC through four common scenarios. "Non-resident" rows assume a typical home-state foreign LLC registration adds about $200 per year of stacked cost; the real number depends on which state you live in and ranges from $50 to over $800 depending on jurisdiction.
| Scenario | Year 1 | Each year after | 3-year total |
|---|---|---|---|
| You live in Delaware, business operates there No foreign LLC registration needed. You pay Delaware fees only. | $510 | $400 | $1,310 |
| You live in Idaho, business operates there No foreign LLC registration needed. You pay Idaho fees only. | $200 | $100 | $400 |
| Non-resident forming in Delaware with operations elsewhere You pay Delaware's fees plus a typical home-state foreign LLC registration of about $200 per year. | $710 | $600 | $1,910 |
| Non-resident forming in Idaho with operations elsewhere You pay Idaho's fees plus a typical home-state foreign LLC registration of about $200 per year. | $400 | $300 | $1,000 |

Formation process, side by side
What actually happens from the moment you start filing to the moment you're in good standing. Use this as a checklist.
Delaware
- Check business-name availability on the Delaware entity search.
- Appoint a registered agent with a physical Delaware street address.
- File Certificate of Formation of Limited Liability Company for $110.
- Wait for approval. Online typically 10 business days. Paid expedite from $100.
- Adopt an operating agreement (recommended, not required by Delaware statute).
- Apply for a federal EIN (free from the IRS).
- Open a business bank account to separate personal and business finances.
- Pay the $300 annual Delaware LLC tax when it comes due.
Idaho
- Check business-name availability on the Idaho entity search.
- Appoint a registered agent with a physical Idaho street address.
- File Certificate of Organization Limited Liability Company for $100.
- Wait for approval. Online typically 7 business days. Paid expedite from $40.
- Adopt an operating agreement (recommended, not required by Idaho statute).
- Apply for a federal EIN (free from the IRS).
- Open a business bank account to separate personal and business finances.
- File your first annual report and pay $0 when it comes due.
Before you pick either state
A few things that apply no matter which state you choose. These trip up enough first-time filers that they're worth stating explicitly.
Registered agent is non-negotiable. Both Delaware and Idaho (and every other US state) require every LLC to designate a registered agent with a physical street address in the state of formation. You can serve as your own agent if you live in the state; otherwise a commercial agent runs $50 to $125 per year. Using your own home address makes it part of the public record.
Forming elsewhere does not escape your home state's tax. If you live and operate a business from your home state, forming the LLC in Delaware or Idaho does not avoid your home state's income tax. The moment you transact business at home, your home state requires a foreign LLC registration, and state tax liability follows your residence regardless of where the entity sits on paper.
EIN applications are free. The IRS issues Employer Identification Numbers directly at no cost. Any service charging you to "get your EIN" is reselling a free form submission. Single-member LLCs with no employees technically don't need one for federal tax, but nearly every bank requires an EIN to open a business account.
Operating agreement matters more than the state you pick. A well-drafted operating agreement governs member ownership, management, profit splits, buy-sell terms, and dissolution. Without one, your LLC runs on the state's default rules, which are rarely what you want. California, Maine, Missouri, and New York require a written one by statute; every other state treats it as strongly recommended.

Frequently Asked Questions
-
Is it cheaper to form an LLC in Delaware or Idaho?
Idaho is cheaper at formation ($100) than Delaware ($110). Ongoing costs are also different: $100 vs $400 per year. Total over three years: $400 vs $1,310.
-
Can I form an LLC in Delaware if I live in Idaho?
Yes, but your Idaho business will almost certainly need to register as a foreign LLC in Idaho too, which means paying Idaho's foreign registration fee and any ongoing Idaho obligations on top of the Delaware ones. The "form elsewhere to save" math usually doesn't work for operating businesses; it only works when you have no physical operations tied to any specific state.
-
How long does it take to form an LLC in Delaware vs Idaho?
Delaware online: 10 business days; Idaho online: 7 business days. Delaware offers paid expedite from $100. Idaho offers paid expedite from $40.
-
Which state has lower taxes for an LLC, Delaware or Idaho?
Delaware: state income tax applies to member-level pass-through income, plus a $300 minimum entity-level tax. Idaho: state income tax applies to member-level pass-through income, no entity-level franchise or LLC tax.
-
Do both states require a registered agent?
Yes. Every US state (and DC) requires every LLC to maintain a registered agent with a physical street address in the state. Delaware and Idaho both have this requirement. You can serve as your own agent if you live in the state; most out-of-state filers use a commercial agent for $50 to $125 per year.
-
Which state should I pick if I run an online business from home?
Form in the state you actually live in. Your home state's Department of Revenue treats your residence as nexus regardless of where the LLC is filed, which means you owe state income tax there anyway. Forming in Delaware or Idaho to escape your home state's tax doesn't work; it adds paperwork. The non-resident filings make sense when you genuinely operate nowhere in particular: international founders, purely passive holding entities, or real-estate LLCs owning property in other states.
