How to Start an LLC in Mississippi (2026): Step-by-Step Guide

Published: June 2026 · Updated for the 2026 tax year

Mississippi is one of the cheapest, simplest states in the country to start an LLC — and one where the math keeps getting better. It's $50 to file, the whole thing is done online, the annual report costs nothing, and the state income tax is on a legislated path to zero. The catches aren't expensive; they're the kind you only find out about when you trip over them: the "free" annual report that quietly dissolves your LLC if you skip it, and an income tax most guides still describe with last year's rate. This guide walks through every step, what a Mississippi LLC actually costs year by year, how to form one from outside the US, and the deadlines you need on your calendar.

A note from Slava

I'm Slava, co-founder and CEO of Jupid. Before this I co-founded and scaled an AI-powered accounting platform to around $30M in revenue and more than 100,000 business users — the kind of company that ends up filing a lot of paperwork in a lot of states and watching customers trip over the same things again and again.

Mississippi is one of the friendliest states on this list. The fee is low, the filing is entirely online, and there's no annual fee to ambush you later. What there is, instead, is a pile of out-of-date third-party advice. A lot of "how to start an LLC in Mississippi" articles still quote a top income-tax rate of 5% — that number is gone. The 2025 Build Up Mississippi Act put the individual income tax on a glide path to zero: it's 4% in 2026 and steps down every year toward elimination. That's a real, ongoing difference to your bottom line, and almost nobody is telling Mississippi LLC owners about it correctly.

The other thing guides bury is the annual report. It's free, so people assume it doesn't matter — and then they don't file it, and the state administratively dissolves their LLC. Free does not mean optional.

So this guide does three things the others skip: it corrects the tax story, it adds up the real cost over time, and it hands you a dated checklist for your first 90 days so the April 15 annual report doesn't catch you. Everything here is current for 2026, with links to the official sources so you can verify before you file.

Should you actually form your LLC in Mississippi?

If you live in Mississippi and run your business from Mississippi, form your LLC in Mississippi. The popular advice to "form in Wyoming or Delaware instead" doesn't help you here: an out-of-state LLC that does business in Mississippi has to register as a foreign LLC with the Secretary of State, keep a registered agent here, and file an annual report — and as a foreign LLC that annual report costs $250 a year, versus $0 for a domestic Mississippi LLC. You'd be paying more, in two states, for the privilege of more paperwork. Mississippi's own costs are about as low as they get, so there's nothing to dodge.

Forming elsewhere makes sense in a narrower set of cases: you genuinely don't operate in Mississippi (no office, employees, or meaningful activity here), you're a non-resident with no US footprint at all, or you have a specific reason — outside-investor expectations, say — that points to Delaware. If you're weighing it, our best state to form an LLC tool walks through the trade-offs, and our Wyoming LLC guide covers the no-income-tax, non-resident case in detail.

For everyone else: Mississippi it is. Here's how.

How to start an LLC in Mississippi, step by step

1. Choose and check your LLC name

Your name has to include "Limited Liability Company" or an abbreviation — "LLC," "L.L.C.," "Limited Company," "LC," or "L.C." ("Limited" can be shortened to "Ltd." and "Company" to "Co.") — and it has to be distinguishable from every other entity on the Secretary of State's records. The comma before "LLC" is optional: "ABC Widgets, LLC" and "ABC Widgets LLC" are both fine. Search the Mississippi business entity search before you get attached to anything. Need ideas or want to check a few options at once? Our Mississippi business name generator is built for that. If you want to lock a name in before you're ready to file, a name reservation holds it for 180 days for $25 — though for most filers it's simpler to just file the Certificate when the name is free.

2. Appoint a Mississippi registered agent

Every Mississippi LLC needs a registered agent — a person or company designated to accept legal papers and official notices on the LLC's behalf — with a physical Mississippi street address. That can be an individual who actually lives in Mississippi (you can be your own LLC's agent if you're a Mississippi resident), or a registered agent company. A P.O. box won't do. The registered agent's name and address go on the public record, which is one reason people who'd rather not publish a home address — and everyone who lives out of state — hire a commercial registered agent for roughly $50–$150 a year.

3. File the Certificate of Formation online

This is the step that creates your LLC, and in Mississippi it's done entirely online. File the Certificate of Formation through the Secretary of State portal at corp.sos.ms.gov for $50 — there is no paper option anymore, so don't go looking for a form to mail. You'll list the LLC name, the registered agent and the Mississippi street address, the management structure (member-managed or manager-managed), the effective date, and contact information. Online filings are usually approved in about one to two business days, and a small card-processing fee may be added at checkout. Mississippi doesn't sell an expedited tier — it's already fast. Once it's approved, download your stamped Certificate; your bank will ask for it.

4. Write an operating agreement

Mississippi doesn't legally require an operating agreement, but every LLC should have one in writing. You don't file it with anyone; you keep it with your company records. It sets out ownership percentages, how profits are split, who can make decisions, and what happens if a member leaves. Even a single-member LLC should have one — it's part of how you keep the liability shield intact and how a bank or investor sees you're running a real entity.

5. Get your EIN from the IRS

An EIN is your LLC's federal tax ID, and you need it to open a bank account, hire anyone, and file taxes. It's free. Apply at irs.gov — if you have an SSN or ITIN, the online application takes a few minutes. If you don't (common for non-resident owners), file Form SS-4 by fax or mail, or call the IRS international phone line; see the non-resident section below. Never pay a third party for the EIN itself — the number is always free from the IRS.

6. Register for Mississippi taxes and local licenses

Forming the LLC doesn't cover your tax registrations. If you sell tangible goods (or taxable services) in Mississippi, register for a sales tax permit through the Department of Revenue's Taxpayer Access Point (TAP) before you start selling — a permit is required per location, and sales/use tax returns are due by the 20th of the month after the period. If you'll have employees, register for Mississippi withholding through TAP and for unemployment insurance with the Mississippi Department of Employment Security, and set up federal payroll. There's no statewide general business license, but many cities and counties require a local privilege license — check with your city hall or county. And any professional or industry license you'd need as a sole proprietor — contractor, cosmetology, food service, alcohol — you still need as an LLC.

7. File your free annual report every April 15

Every domestic Mississippi LLC files an annual report with the Secretary of State by April 15 each year. For a domestic LLC it costs $0 — but it's mandatory, and it's online only. You can file any time on or after January 1. The catch that trips people up is twofold: first, your first annual report is due the calendar year after you form, not the formation year; second, because it's free, people assume it's optional and skip it. It isn't. Miss it long enough and the state begins administrative dissolution — which freezes your ability to do business and forces you to pay reinstatement fees to get back in good standing. Put a reminder on your calendar for late March, every year.

What a Mississippi LLC really costs, year by year

Most guides quote "$50 to file" and stop. Here's the fuller picture — and the good news is that the picture is genuinely cheap.

Year one

Every following year

The "free annual report" trap nobody flags. Because the domestic annual report costs nothing, it's the easiest filing in the country to forget — and forgetting it is exactly how good-standing LLCs get administratively dissolved. There's no invoice to remind you, because there's no fee. Treat April 15 like a hard deadline anyway: file it the same week your taxes are due so the two land together.

The disappearing income tax. This is the part to actually plan around. Mississippi's individual income tax — the rate your LLC's pass-through profits are taxed at — is 4% in 2026 on income above $10,000, and under the Build Up Mississippi Act it steps down to 3.75% in 2027, 3.5% in 2028, 3.25% in 2029, and 3% in 2030, then keeps falling on revenue triggers until it hits 0% and the tax is eliminated. If you're choosing between Mississippi and a higher-tax neighbor, that trajectory matters more than any one-time filing fee.

DIY versus a formation service versus Jupid. Doing it yourself through the SOS portal is genuinely easy and costs the $50 state fee plus your time. A formation service charges $0–$300 on top of that (the "$0" packages still pass through the $50 and then upsell you a registered agent and a "compliance" subscription). Jupid forms your Mississippi LLC for free — you pay only the state filing fee — and then handles the bookkeeping and tax filings afterward, which is where most of the ongoing cost and hassle actually lives.

Forming a Mississippi LLC as a non-resident or foreign founder

You can own a Mississippi LLC without being a US citizen or resident — Mississippi imposes no residency requirement on members or managers. The practical hurdles are a Mississippi registered agent, an EIN, a US bank account, and your US and Mississippi tax filings.

Registered agent. You must list a Mississippi registered agent with a real Mississippi street address on your Certificate of Formation. If no member or manager lives in Mississippi, use a commercial registered agent here — budget around $50–$150 a year. P.O. boxes and mailbox-store addresses don't qualify, and the address is public.

Getting an EIN without an SSN. The IRS online EIN tool requires the responsible party to have an SSN or ITIN, so foreign founders generally can't use it. Instead, file Form SS-4: on the line asking for the responsible party's SSN/ITIN/EIN, write "Foreign" — don't invent a number. Submit it by fax or mail, or call the IRS international EIN line (it's not toll-free), where someone outside the US can get the number over the phone. Check the current Form SS-4 instructions for the right fax and phone numbers, since the IRS changes them. Fax turnaround is usually a few business days; phone is immediate. The EIN is free.

ITIN. An ITIN (Form W-7) is a tax ID for individuals who aren't eligible for an SSN. Your LLC gets an EIN; you as an owner may separately need an ITIN if you have a personal US filing obligation — for instance, if the LLC is engaged in a US trade or business. ITINs are issued with a tax return attached or through an IRS Certifying Acceptance Agent and can take a couple of months.

The Form 5472 obligation — don't skip this. A single-member LLC owned by a non-US person is a "disregarded entity" that generally must file Form 5472 along with a pro-forma Form 1120 every year, reporting reportable transactions between the LLC and its foreign owner — even with no US income. The penalty for missing it is $25,000, plus more for continued failure. It's due with the Form 1120 deadline (generally April 15, extendable to October), and it can't be e-filed by a disregarded entity — it goes in by paper or fax. Almost no Mississippi LLC guide mentions this; build it into your annual calendar from day one.

US bank account. Most US banks want the owner physically present to open a business account, along with the EIN confirmation letter, the filed Certificate of Formation, the operating agreement, and a passport. Several fintech business-banking platforms onboard non-resident-owned US LLCs remotely — eligibility and policies change, so check current terms before you rely on any of them. You'll typically need a US business address, which can be your Mississippi registered agent or a virtual office depending on the bank.

Mississippi tax. If the LLC has Mississippi-source income or operates in Mississippi, expect a Mississippi return, and a nonresident member with Mississippi-source distributive income may face Mississippi nonresident income tax — at the current 4% rate, falling each year under the phase-out. There's no franchise tax on the LLC itself. Federally, if the LLC is engaged in a US trade or business, the foreign owner has US filing obligations of their own (Form 1040-NR for an individual, plus the Form 5472 filing above) — coordinate the effectively-connected-income rules with a US tax pro before your first filing season.

Registered agents and the Corporate Transparency Act (BOI)

Your registered agent is the person or company designated to receive lawsuits and official notices for the LLC, and it has to be a Mississippi resident or a registered agent company with a physical Mississippi street address. Because that address is public, plenty of Mississippi residents hire a commercial agent purely to keep their home address off the record.

On the federal beneficial-ownership side: under the Corporate Transparency Act, LLCs were originally required to file a Beneficial Ownership Information (BOI) report with FinCEN. That changed. FinCEN's interim final rule, published March 26, 2025, redefined a "reporting company" to mean only entities formed under foreign law that register to do business in a US state. As of early 2026, that means a Mississippi-formed LLC — even one with foreign owners — has no BOI filing obligation. It's still an interim final rule, and FinCEN has said it intends to finalize one in 2026, so this could shift; check fincen.gov/boi before you assume one way or the other. (If you register a foreign-formed entity to do business in Mississippi, the BOI rules still apply to that entity.)

Your first 30, 60, and 90 days

Days 1–30

• Get your EIN from the IRS (free; online if you have an SSN/ITIN, otherwise by fax, mail, or phone).
• Adopt your operating agreement — not required by Mississippi, but kept with your records.
• Confirm your registered agent designation is on file with the Secretary of State.
• Open a US business bank account (EIN letter, filed Certificate of Formation, operating agreement, ID).
• Check your city and county for a local privilege license and apply if required.
• Check your BOI status. As of early 2026 a domestic Mississippi LLC has no FinCEN filing to make; re-verify at fincen.gov/boi.

Days 31–60

• Register for a Mississippi sales tax permit through the DOR's TAP portal if you sell tangible goods; register for withholding if you'll have employees, and set up federal payroll.
• Set up bookkeeping. If profit will consistently clear roughly $40,000–$50,000, look into an S-corp election (Form 2553) with your accountant.
• Get any professional or industry licenses your work requires.
• Look into business insurance — general liability now, workers' comp once you have employees.
• If you're a foreign-owned single-member LLC, note the annual Form 5472 + pro-forma 1120 filing.

Days 61–90

• Calendar the annual report deadline: April 15 every year, free for domestic LLCs but mandatory — and remember the first one is due the year after formation. Set a reminder for late March.
• Document member contributions, ownership percentages, and contracts.
• Note the in-effect Mississippi income-tax rate for the year (4% in 2026, stepping down annually) so your estimated payments are right, and re-check FinCEN BOI guidance at fincen.gov/boi.

Common mistakes with Mississippi LLCs

Skipping the free-but-mandatory annual report. Why it hurts: because it costs nothing, there's no invoice to remind you — so people forget it, and the state administratively dissolves the LLC, freezing your ability to do business and forcing you to pay reinstatement fees. Fix: file it by April 15 every year (you can file from January 1), and the first time it's due is the year after you form. Calendar a reminder for late March.

Looking for a paper form to mail. Why it hurts: Mississippi is online only and no longer accepts mailed Certificate of Formation filings, so time spent printing and mailing is wasted — and old guides still describe a paper path. Fix: file through corp.sos.ms.gov; approval usually comes in one to two business days.

Planning around an outdated income-tax rate. Why it hurts: many guides still quote a top rate of 5%. Under the Build Up Mississippi Act it's 4% in 2026 and falling toward zero — getting the rate wrong throws off your estimated taxes and your state-choice math. Fix: use the current year's rate (4% for 2026, on income over $10,000) and check dor.ms.gov for the in-effect figure each year.

Thinking a Wyoming LLC dodges Mississippi's costs. Why it hurts: if you operate in Mississippi, the out-of-state LLC has to register here as a foreign LLC — which means a registered agent here and a $250-a-year foreign annual report, versus $0 for a domestic Mississippi LLC. You pay more in two states. Fix: if Mississippi is where you do business, form in Mississippi. Its costs are already among the lowest in the country.

Forgetting the local privilege license. Why it hurts: many Mississippi cities and counties require a local privilege license, and operating without one can mean back fees and penalties. Fix: call your city hall or county government in your first month and ask exactly what they need.

Frequently asked questions

How much does it cost to start an LLC in Mississippi in 2026? The state filing fee for the Certificate of Formation is $50, filed online through corp.sos.ms.gov (Mississippi no longer accepts paper). The EIN is free, and the annual report is free. So a do-it-yourself Mississippi LLC costs about $50 to form, plus an optional registered agent service (~$50–$150 a year) if you don't have your own Mississippi street address. It's one of the cheapest states in the country to start and keep an LLC.

Does Mississippi have an annual LLC fee? No fee — but a required filing. Every domestic Mississippi LLC must file an annual report with the Secretary of State by April 15 each year, and for domestic LLCs it costs $0. It is mandatory, though: if you don't file, the state can administratively dissolve your LLC. (Foreign LLCs registered in Mississippi pay $250 a year.) The first annual report is due the calendar year after you form.

Do I need a registered agent for a Mississippi LLC? Yes. You must list a Mississippi registered agent with a physical Mississippi street address on your Certificate of Formation. It can be you or another Mississippi resident, or a commercial registered agent. P.O. boxes are not allowed, and the address is public record.

Can a non-US resident own a Mississippi LLC? Yes. Mississippi has no citizenship or residency requirement for members or managers. You'll need a commercial registered agent in Mississippi and an EIN (which you can get without an SSN). If your LLC is a single-member foreign-owned disregarded entity, you'll also have to file Form 5472 with a pro-forma Form 1120 every year — the penalty for missing it is $25,000.

What is Mississippi's income tax rate in 2026, and is it really going away? Mississippi's individual income tax is 4% on taxable income above $10,000 in 2026 (the first $10,000 is exempt). Under the 2025 Build Up Mississippi Act it steps down each year — 3.75% in 2027, 3.5% in 2028, 3.25% in 2029, and 3% in 2030 — then continues falling on revenue triggers until it reaches 0% and the tax is eliminated. LLC profits pass through and are taxed at that individual rate; there's no separate franchise tax on the LLC.

How long does it take to form an LLC in Mississippi? Mississippi is online only, and online filings are usually approved in about one to two business days. There's no state expedited tier to pay for — and because it's already fast, you rarely need one.
