Starting a Business
Do I Need a Lawyer to Form an LLC?
Filing the LLC paperwork itself is genuinely DIY-able — most secretaries of state offer online filing for $50–$300. But a single-member LLC with no operating agreement, sloppy commingling of business and personal money, and no S-corp election analysis is barely worth more than a sole proprietorship in real liability protection. The lawyer's value is the operating agreement, the tax election, and the formation steps non-lawyers skip.
The Short Answer
DIY filing the articles of organization is fine. What you actually need a lawyer for is: operating agreement (especially with multiple members), S-corp election analysis, EIN strategy, multi-state qualification, and the corporate-formality steps that preserve limited liability. Total lawyer cost for a competent formation package: $750–$2,500. LegalZoom's templates are mediocre and miss state-specific requirements.

What you can DIY
Filing the Articles of Organization (or Certificate of Formation) with your state. Most states have online filings — Delaware $90, California $70, Texas $300, Florida $125, New York $200.
Getting an EIN from the IRS. Free online application; takes 15 minutes.
Opening a business bank account. Bring articles, EIN, and operating agreement.
Buying basic business insurance. General liability + professional liability where applicable.
All of the above can be done in a weekend without legal help. The state filing alone takes 30 minutes.
When you really need a lawyer
Multiple owners (members). The operating agreement governs everything: profit splits, voting rights, decision authority, what happens when someone wants out, what happens on death or disability, dispute resolution. LegalZoom templates are inadequate. Real-world disputes between co-founders without a real operating agreement can cost $50,000–$500,000 to litigate.
S-corp election analysis. An LLC can elect to be taxed as an S-corp by filing IRS Form 2553. Done correctly, it can save 7.65% (the self-employment tax on the salary-vs-distribution split) on every dollar of profit above a reasonable salary. Done incorrectly, it triggers IRS scrutiny and back taxes.
Multi-state operations. An LLC formed in Delaware that operates in California must register as a "foreign LLC" in California — including the $800 minimum franchise tax. Wrong setup = expensive penalties.
Real estate or investment LLCs. Series LLCs, holding-company structures, single-member disregarded entities for asset protection — these are technical.
Capital raising / outside investors. Securities laws apply (federal Reg D, state blue-sky laws). DIY here is a federal crime.
Professional services (medical, legal, accounting). PLLC or PC structures are required in many states; rules on owner qualifications are technical.
Foreign owners. Non-resident-alien tax withholding, BE-13 reporting, and FIRPTA all change the structure.
Why operating agreements matter
An operating agreement is the contract between LLC members (or, in a single-member LLC, between you and the world). It's where the real liability protection lives.
Without an operating agreement, your LLC defaults to your state's LLC statute — usually a generic, member-friendly framework that's the wrong fit for most businesses.
Critical clauses: capital contributions (who owes what when); profit and loss allocation; distributions (timing and amount); management structure (member-managed vs. manager-managed); voting rights (per-member or per-share); decision thresholds for major actions; restrictions on transfers; buy-sell triggers and pricing; deadlock resolution; dispute resolution (mediation/arbitration); winding up.
Single-member LLCs need operating agreements too. Courts increasingly pierce the corporate veil for single-member LLCs without operating agreements and adequate corporate formalities.
Operating agreements typically run 25–60 pages from a real lawyer. LegalZoom's run 10–20 pages and miss critical clauses.
The S-corp election decision
By default, a single-member LLC is taxed as a sole proprietorship; a multi-member LLC is taxed as a partnership. Both pay self-employment tax (15.3%) on all net income up to the Social Security wage base.
An LLC can elect to be taxed as an S-corporation by filing Form 2553 within 75 days of formation (or by March 15 of the tax year for existing LLCs).
S-corp benefit: only the "reasonable salary" portion is subject to self-employment tax. The remaining profit is distributed to the owner without SE tax.
Example: $200,000 net income. As LLC: $200,000 × 15.3% × half-deductible = $24,580 in SE tax. As S-corp with $80,000 reasonable salary: $80,000 × 15.3% = $12,240 in payroll tax. Savings: $12,340/year.
But: S-corp requires payroll, formal corporate records, no foreign owners, no more than 100 shareholders, only one class of stock (generally), and U.S. citizens/residents only. The compliance cost is $500–$2,000/year in payroll services.
S-corp is usually wrong for: businesses with significant losses (passive-activity rules limit deduction), businesses planning to take outside investment, businesses with non-resident-alien owners.
Get a CPA or tax lawyer to run the analysis before you elect. The election is hard to undo.
What does LLC formation cost?
DIY (state filing only): $50–$300 depending on state.
LegalZoom-class formation package: $300–$1,000 (plus state fees). Includes generic operating agreement template.
Lawyer-drafted formation (single-member): $750–$1,500. Includes filing, custom operating agreement, EIN, S-corp election analysis.
Lawyer-drafted formation (multi-member): $1,500–$3,500. Real custom operating agreement covering capital, voting, transfers, buy-sell.
Holding-company structures, real estate LLCs, multi-state setups: $2,500–$10,000+.
Annual maintenance: $50–$800 in state-mandated annual reports plus accountant fees ($500–$2,000) and any payroll services ($500–$2,000) for S-corp.
What goes wrong in DIY LLC formations
Veil-pierce risk. Without operating agreement, without separate bank account, without paying yourself a real salary, and with personal expenses run through the LLC, courts pierce the corporate veil and you're personally liable.
S-corp election missed deadline. The 75-day window from formation is short. Many DIY founders don't realize they need to elect at all and lose thousands per year in unnecessary self-employment tax.
Wrong state of formation. Forming in Delaware when you operate in California costs you the $800 California franchise tax PLUS Delaware fees PLUS foreign-LLC registration. Net loss.
Inadequate operating agreement. Generic templates miss state-specific requirements (California, Florida, New York all have unique rules).
Multi-member without buy-sell. Two co-founders with a 50/50 split, no buy-sell agreement, and no deadlock-resolution mechanism = guaranteed expensive litigation when they disagree.
Sole-prop with LLC name. Continuing to receive payments to your personal name after forming the LLC. The LLC structure does nothing — money still flows to you personally.
Forgotten compliance. Annual reports, biennial statements (NY), franchise tax (CA, TX, DE), registered-agent updates. Missed = administrative dissolution = no liability protection.
EIN not obtained or used. Operating an LLC under a personal SSN signals to courts and creditors that the LLC is a sham.

Frequently asked questions
Should I form my LLC in Delaware?
Probably not, unless you're planning to take venture capital or operate in multiple states. Form in the state where you operate. Delaware adds cost and complexity for most small businesses.
Single-member LLC vs. multi-member LLC?
Single-member is taxed as a sole proprietorship by default (or S-corp if elected). Multi-member is taxed as a partnership by default (or S-corp/C-corp if elected). The structure depends on owners and tax goals.
LLC vs. S-corp vs. C-corp?
LLC = flexible state-law entity, default partnership tax. S-corp = federal tax election available to LLCs and corporations, saves self-employment tax. C-corp = double taxation, but required for VC funding. Choose based on growth path and tax profile.
Do I need a registered agent?
Yes. Every LLC must have a registered agent with a physical address in the state of formation. You can be your own (free) or hire a service ($100–$300/year).
Will an LLC really protect my personal assets?
If you maintain corporate formalities — separate bank account, operating agreement, no commingling of funds, properly capitalized — yes. Skip those, and courts pierce the veil.
How much does it cost to keep an LLC active?
State annual report ($0–$800), accounting ($500–$2,000), tax preparation ($500–$2,500), and any S-corp payroll services ($500–$2,000). Total roughly $1,500–$8,000/year for an actively managed LLC.
