Best Kentucky LLC Formation Service in 2026
Kentucky has the cheapest LLC filing fee in the entire country — $40 — and a $15 annual report on top. On paper it looks like an unbeatable budget option. The catch most founders miss is the LLET (Limited Liability Entity Tax): every Kentucky LLC owes a $175 minimum annually to the Department of Revenue, on top of the SOS fees. So the real ongoing cost is $190/yr, not $15.
That changes the math, especially for non-US founders. Here's the honest comparison of services.
Quick verdict
| Service | Best for | Filing fee (Kentucky) | Service fee | Reg. Agent | EIN included | Non-US friendly |

| Doola | Non-US founders, one-person company | $40 | from $297 (Starter) | ✅ 1 yr | ✅ (incl. SS-4 paper filing) | ⭐⭐⭐⭐⭐ |
| Northwest | US residents wanting privacy | $40 | $39 + state | ✅ 1 yr | ❌ (+$50) | ⭐⭐⭐ |
| ZenBusiness | US residents, low budget | $40 | $0 (Starter) | ✅ 1 yr | ❌ (+$99) | ⭐⭐ |
| LegalZoom | US residents wanting brand | $40 | $0 (Basic) | $249/yr | ❌ (+$79) | ⭐⭐ |
| Bizee (formerly IncFile) | US residents, free starter | $40 | $0 + state | ✅ 1 yr | ❌ (+$70) | ⭐⭐ |
| DIY (Kentucky SOS direct) | Founders with US SSN + address | $40 | $0 | ❌ ($125+/yr separately) | DIY (free with SSN) | ⭐ |
Our recommendation for non-US founders: Doola — bundles LLC + EIN (SS-4 paper for non-SSN founders) + Registered Agent + Mercury Bank introduction in one flow.

Kentucky LLC basics
- Filing fee: $40 (Articles of Organization, one-time, online) — lowest in the US
- Annual report: $15 per year, due by June 30
- LLET (Limited Liability Entity Tax): $175 minimum annually to the Kentucky Department of Revenue. LLCs over $3M revenue pay more on a sliding scale.
- State income tax: 4% flat personal income tax on Kentucky-sourced income; Kentucky honors federal pass-through treatment
- Privacy: registered agent's name and address are public; members are not required on the public filing
- Veteran perk: 51%+ veteran-owned LLCs qualify for free filing and 4 years of waived annual report fees under the Boots to Business program
- Processing: online approval is immediate; mail is 1 business day plus transit
The LLET is the trap. Kentucky's $40 filing fee gets it onto every "cheapest state" list, but a one-person company actually pays ~$190/year minimum once you include the LLET. That's still cheap — but it's not free.
Service-by-service breakdown
1. Doola — best for non-US founders forming a Kentucky LLC
- Pricing: Starter $297/yr, Total Compliance $799/yr
- Includes: LLC filing + EIN (SS-4 paper for non-SSN founders) + Registered Agent (1 yr) + US business address + Mercury Bank introduction
- Turnaround: 2–4 weeks for non-US founders (EIN bottleneck), same-day for US founders thanks to Kentucky's immediate online approval
- Why we use it: The SS-4 paper EIN handling. Doing it yourself from outside the US adds 6–12 weeks before you can open a bank account.
- Caveat: Doola does not file the LLET return for you on the Starter plan — that's still on you (or your CPA). Total Compliance bundles tax filing.

Step-by-step Kentucky LLC formation
- Choose a name — must include "LLC", "L.L.C.", or "Limited Liability Company". Check at the Kentucky SOS business search.
- Designate a registered agent — must have a physical Kentucky street address (no PO Boxes).
- File Articles of Organization — $40 to the Kentucky Secretary of State. Online approval is immediate.
- Get an EIN from the IRS — free online with SSN. Non-US founders file SS-4 by fax/mail, 4–8 weeks. Doola does this for you.
- Register with the Kentucky Department of Revenue — via the Business One Stop Portal, for the LLET and any sales/withholding tax accounts.
- Open a US business bank account — Mercury Bank, 3-hour approval if your LLC + EIN are clean.
- File the Annual Report ($15) + LLET return ($175 minimum) — annual report by June 30; LLET by April 15 every year.
Kentucky's quirk: The $40 filing fee makes Kentucky look like the cheapest state in the US, but the $175 LLET minimum makes it ~3x more expensive than Wyoming ($60/yr) for a typical one-person LLC. Form here if you have actual Kentucky operations, not for paper-cheap formation.
FAQ
Why is Kentucky's filing fee so cheap?
Kentucky's $40 SOS filing fee is the lowest in the US. The state recovers revenue on the back end via the LLET ($175 minimum/year). Net-net, you pay similar amounts to mid-tier states.
Can a non-US resident form a Kentucky LLC?
Yes. No citizenship or residency requirement. You need a Kentucky-based registered agent (any service above) and an EIN, which Doola files by SS-4 paper if you don't have an SSN.
Do I really have to pay the $175 LLET if I make no money?
Yes. The $175 is the minimum LLET regardless of revenue. There's no "inactive" exemption — if your LLC exists, you owe it.
Is Kentucky better than Wyoming for a non-US founder?
No. Once you include the LLET, Kentucky is more expensive than Wyoming, has weaker privacy, and the state income tax kicks in if you have local operations. Pick Kentucky if you actually do business there. See our best state for LLC comparison.
