LLC Cost Methodology: How LLC Formation Cost Is Calculated

Every LLC fee on this site comes directly from the Secretary of State office that charges it. No estimates, no copy-paste from a competitor’s page, no AI-hallucinated numbers. This is the public methodology behind that data.

TL;DR

The 5-year LLC cost figure on every state page combines six measurable inputs: the state filing fee, the annual or biennial report fee, the franchise tax (where one applies), the registered-agent service market rate, optional add-on services (operating agreement, EIN service, expedite), and any state-mandated publication cost. We pull each of the first three from the state’s Secretary of State or Department of Revenue website and timestamp the verification with a lastVerifiedDate flag. Verified data is refreshed on a 90-day cadence. Anything older than 90 days renders with an orange freshness warning. We never quote a figure we can’t link back to a .gov URL or an IRS publication, and we publish the underlying dataset as CSV for anyone who wants to audit it.

The six cost components we measure

LLC cost is a stack, not a single number. Five-year total cost of ownership for a US LLC formed in 2026 breaks down across six line items:

1. State filing fee — the one-time fee charged by each state’s Secretary of State office to register the Articles of Organization (or Certificate of Formation, in some states). Range: $35 (Montana) to $500 (Massachusetts). Source: each state’s SOS website.
2. Annual or biennial report fee — a recurring filing required by 43 states + DC to keep the LLC in good standing. Cadence varies (annual, biennial, decennial). Range: $0 (Arizona, Missouri, New Mexico, Ohio, South Carolina, Texas under threshold, Mississippi) to $500 (Massachusetts).
3. Franchise tax or net worth tax — a few states impose a state-level entity tax on top of the report fee. California ($800/yr minimum), Delaware ($300/yr flat), Tennessee ($300+ sliding), Alabama ($50/yr), New York filing fee tied to gross income, Texas margin tax above $1.23M revenue. Most states have none.
4. Registered agent service market rate — every state requires the LLC to maintain a registered agent with a physical street address in the formation state. Founders living in the formation state can act as their own RA at $0. Otherwise, market rates run $50/yr (Wyoming Registered Agent Services) to $249/yr (LegalZoom).
5. Operating agreement cost — five states (CA, DE, ME, MO, NY) legally require an operating agreement. The other 45 do not require one but bank account opening usually does. Tiers: free SBA template ($0), online template ($39-$99), attorney-drafted single-member ($400-$800), attorney-drafted multi-member with profit/loss allocations ($800-$1,500). Source: American Bar Association Section of Business Law model OA library — last verified 2026-04-25.
6. Publication or notice cost — three states (New York, Arizona, Nebraska) require newspaper publication of formation notice. New York is the most expensive: $1,200-$2,000 in Manhattan, $200-$500 in upstate counties. Arizona: $30-$300, exempt in Maricopa and Pima counties. Nebraska: $40-$200.

The 5-year total = filing fee + (annual fee × 5) + (franchise tax × 4 — most states exempt year 1 or charge it post-formation) + (RA fee × 5 if hired) + operating agreement + one-time publication. Year-1 total = filing fee + first-year report + first-year franchise tax (where applicable, often exempted) + RA fee + operating agreement + publication.

Where the data comes from

Each of the 51 jurisdictions (50 states + D.C.) publishes its LLC fees online. We verify directly against the source, not against secondary aggregators. Below is the full source list as of the 2026-04-25 verification cycle.

Primary state Secretary of State sources

Federal sources

• IRS Apply for an EIN online — confirms the EIN is free; used to debunk paid EIN service value.
• IRS Form 2553 (S-corp election) — used for the S-corp election section.
• IRS Form 8832 (entity classification) — single-member-vs-multi-member tax classification rules.
• IRS Form 5472 (foreign-owned LLCs) — non-resident LLC owner reporting.
• IRS Limited Liability Company (LLC) overview — federal tax classification baseline.
• IRS Publication 535 (Business Expenses) — deductibility of LLC fees and franchise taxes.
• Social Security Administration 2026 contribution and benefit base — used for 2026 self-employment tax wage base ($168,600).
• FinCEN Beneficial Ownership Information (BOI) — Corporate Transparency Act reporting requirements.
• SBA Apply for Licenses and Permits — used for industry-specific compliance cost adders.
• American Bar Association Section of Business Law — operating agreement model library and PLLC requirements.

Verification cadence

Each fee is rechecked on a 90-day cycle. The verification log lives at the bottom of every page in the lastVerifiedDate field. When the date is older than 90 days, the figure renders in subtle orange with a “verification pending” footer — never blocked, never hidden. This is on purpose. We’d rather show 95-day-old data with a freshness warning than silently age stale data.

The verification process runs on the calendar quarter:

• Q1 cycle (January) — re-fetch all SOS pages, diff against prior quarter, update changed values, log changes in the public changelog.
• Q2 cycle (April) — repeat. Most state fee changes hit on July 1 (state fiscal-year transitions) so April is a baseline.
• Q3 cycle (July) — most aggressive cycle. Several states change fees here (NV did this in 2024; FL adjusts annual report price points occasionally).
• Q4 cycle (October) — pre-year-end pass to capture any ad hoc legislative changes.

Between cycles, breaking news (court rulings, emergency legislation) triggers an off-cycle update. The 2024 Corporate Transparency Act enforcement timeline is one example: we updated our BOI guidance four times in Q1 2024 as the FinCEN deadline shifted.

How we handle disputed or ambiguous fees

A few fees defy a single-number answer. Three examples:

California $800 franchise tax exemption. AB 85 (2020) waived the first-year $800 minimum franchise tax for LLCs formed 2021-2023. The exemption sunset was extended by AB 1138 (2022) and verification of current-year applicability requires checking the Franchise Tax Board’s current-year LLC bulletin. For the 2026 cycle, our verified position is that the first-year exemption is no longer in effect — newly formed CA LLCs in 2026 owe the $800 minimum franchise tax in year 1. This is sourced directly from the FTB’s current LLC publication, last verified 2026-04-25.

New York filing fee tied to gross income. Beyond the $200 formation fee, NY imposes an annual LLC filing fee on any LLC treated as a partnership for tax purposes. The fee scales with gross income from $25 (under $100K) to $4,500 (over $25M), per tax.ny.gov. We surface this as a separate line — not folded into the formation fee — because most founders confuse it with the $200 SOS filing fee.

Texas franchise tax under the no-tax-due threshold. Texas requires every LLC to file an annual Public Information Report and Franchise Tax Report by May 15. Most LLCs (those under $1.23M annual revenue in 2026) owe $0 franchise tax — but they must still file. We list TX as a “$0 ongoing fee” state for typical small-business users, with a footnote explaining the filing requirement.

When a fee is genuinely in flux (mid-legislative-session changes, pending court cases), the page renders with a “data verification in progress” banner instead of a number. We’ve used this pattern twice in two years — both times during the FinCEN BOI rule freezes.

Currency, rounding, and edge cases

All figures are in US dollars (USD) without inflation adjustment. The 2026 figures are 2026 nominal dollars as charged. We do not project 2027+ figures because state legislatures change fees unpredictably; instead, the 5-year total assumes current 2026 fees hold flat — which is the convention used by LegalZoom’s state-by-state cost guide and the SBA business cost worksheets.

Rounding: the table values are exact as charged. The 5-year total is computed as filing fee + (annual fee × 4 ongoing years after year 1) + year-1 specifics, then rounded to the nearest dollar.

Edge cases handled in the calculator and on state pages:

• Zero-fee annual report states (AZ, MO, NM, OH, SC, TX-under-threshold, MS). Calculator outputs “$0 / no annual report” with a label, not a bare $0.
• Biennial filers (CA, NY, IA, IN, NE, AK, DC). 5-year ongoing = report fee × 2 (the report fires in years 2 and 4 after formation typically; CA-specific cadence verified separately).
• Decennial filers (Pennsylvania). $70 every 10 years. 5-year average ongoing = $7/year (we do not include this as a year-1 cost — it appears in year 11 if you formed in 2026).
• States with publication requirement (NY, AZ, NE). Publication cost is not added to the headline 5-year total because it varies wildly by county and is paid to private newspapers, not the state. Instead, it appears in a “Hidden costs” callout with the source URL for each state’s official publication FAQ.
• States requiring registered agent to be a resident. All 50 states require the RA to have a physical street address in the formation state. If the founder doesn’t live there, the calculator defaults to assuming a $120/yr commercial RA service.
• First-year tax exemptions. California’s first-year $800 franchise tax was waived under AB 85 for LLCs formed 2021-2023; we verify the current-year FTB bulletin and update the calculator each January. As of 2026-04-25, the exemption is not in effect for LLCs formed in 2026.

What we don’t include in the headline cost

The calculator and state pages compute direct LLC entity cost. Several adjacent costs are intentionally excluded because they vary per business and would mislead a comparison:

• Federal income tax — depends on the owner’s tax bracket and entity tax classification.
• State income tax on owners — pass-through to personal returns; varies by owner’s state of residency.
• Self-employment tax — 15.3% on net SE earnings up to the 2026 SSA wage base of $168,600. Detailed in our LLC tax cost calculator spoke.
• City and county business licenses — typically $25-$500/yr depending on jurisdiction. Cited per locality in our hidden costs spoke.
• Sales tax permit registration — usually free or under $50, but registration is required in any state where you have nexus.
• Workers compensation insurance — required in 49 states (Texas is the exception; opt-out allowed). Premiums depend on payroll and industry.
• Foreign qualification fees — $100-$750 per outside state where you have nexus, plus that state’s annual report. The home-state vs Wyoming/Delaware myth math is detailed in our pillar page and the Delaware vs Wyoming comparison spoke.

These are surfaced in the “What this doesn’t include” callout on every state and result page. We don’t bury them. The point of the calculator is that it gives a defensible direct LLC cost — not a complete business-cost projection.

How to suggest a correction

If you find a stale or wrong number, email [email protected] or open an issue at the public correction tracker. Each correction triggers a re-verification against the source URL, and corrections are logged with the date and the corresponding source. Common types of corrections we receive:

• A state changed its fee (most common in Q3 around fiscal-year transitions)
• A state added a new fee category (rare; happened with NV’s 2024 restructure)
• A federal rule shifted (FinCEN BOI is the most active in this category)
• A typo in a number we entered correctly into the dataset but rendered incorrectly in the page

Corrections older than 30 days without a documented response are escalated to the editor. Our correction-handling SLA is 5 business days from receipt.

Reviewer attribution

This methodology and the underlying data are pending external review by a credentialed reviewer (CPA or licensed attorney). The reviewer slot is open as of 2026-04-25 and will be filled before the v1 launch. Once filled, the reviewer’s name, credential, license number where applicable, and review date will appear at the top of every page. The data is compiled and maintained by Aissam Baidi, founder and researcher of US business formation costs (LinkedIn).

Frequently asked questions

How often is the data refreshed?

Every 90 days at minimum, on a quarterly cycle (January, April, July, October). Off-cycle updates happen when a state announces a fee change or a federal rule shifts. Each page shows its own lastVerifiedDate so readers can judge freshness independently of the site-wide cycle.

Can I cite this data in a research paper?

Yes. The dataset is published under CC BY 4.0. Cite as: Baidi, A. (2026). LLC Cost Methodology and Dataset. llcformationcost.com/methodology. Last verified 2026-04-25. Citations to specific state values should reference the state SOS URL listed in the table above, since that is the primary source we ourselves are quoting.

Why do you not list a single “average LLC cost”?

Because the median is misleading. The 51-jurisdiction filing fee distribution is bimodal — a cluster around $50-$150 (most states) and a long tail of expensive outliers (MA $500, TN $300, TX $300). The mean would be pulled up by outliers; the median ($100) would understate the cost of LLCs in expensive states. We publish the full distribution and let readers choose their reference state.

How do you handle disputed fee figures (e.g., when one secondary source says $X and another says $Y)?

We don’t use secondary sources. Every fee on this site is sourced from the state’s own .gov website or an IRS publication. If the SOS page is unclear or under maintenance, we wait — we don’t reach for a faster but lower-quality source.

Does this methodology page fall under E-E-A-T scrutiny?

Yes. The methodology + author bio + reviewer block are the EEAT signals Google looks for on YMYL (“your money or your life”) content. Every state page links back here so readers (and ranking algorithms) can audit the data trail. The methodology page is itself written to be a citable reference — the kind a Wikipedia editor or academic paper could link.

What’s the licensing on the data?

CC BY 4.0. Use it freely with attribution to llcformationcost.com. We deliberately picked the most permissive Creative Commons license short of public domain because the data is itself sourced from state .gov websites that are public-domain or near-public-domain. Aggregating it adds value (single CSV, normalized field names, verification dates) but the underlying numbers belong to the public.
