EIN vs LLC in 2026: What You Actually Need to Start a US Business
If you've been Googling "EIN vs LLC" at 1 a.m. while filling out a Stripe application, you're not alone.
The two terms get mashed together in startup forums, but they solve completely different problems.
One is a tax ID.
The other is a legal structure.
You might need both, one, or neither, depending on what you're actually trying to do in 2026.
This guide walks through what each one is, when you legally need it, what they cost, and the exact order I'd register them in today.
I'll share what worked when I helped a friend launch a two-person Shopify store in Austin last September, plus the IRS rules that changed for the 2026 tax year.
EIN vs LLC: What's the Actual Difference?
Here's the cleanest way to think about it.
An EIN is a nine-digit number the IRS gives your business to identify it on tax forms, just like your Social Security Number identifies you.
An LLC is a legal entity registered with your state that separates your personal assets from your business liabilities.
They're not interchangeable.
An LLC is a thing your business is.
An EIN is a number your business has.
You can have an EIN without an LLC (sole proprietors do this all the time).
You can also have an LLC without an EIN if you're a single-member LLC with no employees, though most banks won't open a business account without one.
I made this mistake myself in 2023.
I assumed getting an EIN somehow protected my personal assets.
It doesn't.
The EIN is just a tax ID.
Liability protection comes from the LLC, the corporation, or whatever entity structure you formally register with your state.
Do You Legally Need an LLC to Start a Business in 2026?
No.
You can legally operate as a sole proprietor in all 50 states without filing anything, as long as you're using your own legal name.
The moment you start operating under a different name, like "Austin Coffee Roasters," you'll need either a DBA (doing business as) registration or an actual entity like an LLC.
That said, here's when an LLC actually starts to matter:
- You're handling client money, inventory, or anything that could be sued over
- You want to open a business bank account without commingling funds
- You're bringing on a co-founder or business partner
- You're applying for business credit, a Shopify Capital loan, or Stripe Atlas
- You're earning more than roughly $40,000–$50,000 in net profit and considering an S-corp election later
Last September I helped a friend in Austin file her LLC for a small e-commerce shop.
She was already doing about $3,200/month in revenue selling handmade ceramics on Etsy and Shopify.
The LLC cost $300 to file with the Texas Secretary of State, took 4 business days to approve, and gave her the legal separation she needed before she signed her first wholesale contract with a local boutique called Parts & Labour.
When the IRS Requires You to Get an EIN
The IRS publishes a clear list, but it's buried on Form SS-4.
Here's the short version.
You must get an EIN if any of these apply:
- You have employees (even one part-time worker getting a W-2)
- You operate as a corporation or partnership
- You file employment, excise, or alcohol/tobacco/firearms tax returns
- You withhold taxes on income (other than wages) paid to a non-resident alien
- You have a Keogh plan or solo 401(k)
- You're involved with certain trusts, estates, or non-profits
If none of those apply and you're a single-member LLC or sole proprietor, you can technically use your SSN.
But I'd still recommend getting an EIN.
It's free, it takes about 10 minutes on the IRS website, and it keeps your SSN off vendor W-9 forms and 1099s.
According to the SBA's 2025 Small Business Profile, identity theft involving misused SSNs cost US small business owners an estimated $1.2 billion last year.
An EIN is a free defense.
Real Cost Comparison: EIN, LLC, and DBA in 2026
The actual out-of-pocket cost varies wildly by state.
Here's what you're looking at today.
| Item | Cost (2026) | Processing Time | Who Issues It |
|---|---|---|---|
| EIN (federal tax ID) | $0 | Immediate online | IRS |
| DBA / Fictitious Name | $10–$100 | 1–14 days | County or state |
| LLC formation (filing fee) | $35–$520 | 1–15 business days | Secretary of State |
| Registered Agent (if needed) | $0–$300/year | Same day setup | You or a service |
| LLC annual report / franchise tax | $0–$800/year | Annual filing | Secretary of State |
| Operating Agreement (template) | $0–$200 | 1 day | You or attorney |
The EIN is genuinely free.
If a website is charging you $79 or $149 for an EIN, they're charging for the convenience of filling out the form for you.
Go straight to irs.gov, click "Apply for an EIN Online," and you'll have your number in under 15 minutes.
I've done this five times now for different projects.
Tax Treatment: How EIN and LLC Decisions Affect Your Return
This is where people get tripped up.
An LLC by itself doesn't change how you're taxed.
By default, the IRS treats a single-member LLC as a "disregarded entity," meaning your business income flows onto your personal Schedule C, exactly like a sole proprietor.
What changes the tax treatment is the election you file.
You can ask the IRS to tax your LLC as an S-corporation by filing Form 2553.
That's typically worth doing once your net business profit hits around $40,000–$50,000 per year, because S-corp election lets you split income between salary and distributions, saving you on self-employment tax.
| Structure | 2026 Self-Employment Tax | Federal Form | Best For |
|---|---|---|---|
| Sole proprietor | 15.3% on all net profit | Schedule C (1040) | Side income under $40k |
| Single-member LLC (default) | 15.3% on all net profit | Schedule C (1040) | Same income, plus liability shield |
| LLC taxed as S-corp | 15.3% on salary portion only | Form 1120-S + W-2 | Net profit $40k–$200k |
| Multi-member LLC (default) | 15.3% per partner share | Form 1065 + K-1s | Two or more owners |
| C-corporation | 21% flat corporate rate | Form 1120 | Raising VC funding |
According to the IRS Tax Statistics report (2024 data, released May 2025), about 71% of S-corporations have receipts under $500,000, which tells you S-corp election is mainstream small-business territory, not just for big firms.
The Order I'd Register Things in Today
If I were starting fresh tomorrow with the same lessons I've learned, here's the exact sequence I'd follow.
- Pick your business name and check availability. Search your state's Secretary of State database and the USPTO trademark database (uspto.gov/trademarks).
- Buy the domain immediately. Even $12 on Namecheap is worth it before someone grabs it.
- File your LLC with the state. This locks in your legal name.
- Get your EIN from irs.gov the same day your LLC is approved.
- Open a business bank account. Chase, Mercury, and Bluevine all accept LLCs with EINs.
- Set up bookkeeping in QuickBooks, Wave, or even a Google Sheet from day one.
- File for an S-corp election only when your projected net profit crosses $40,000.
I skipped step 6 the first time around and spent a brutal weekend in March 2024 reconstructing 11 months of transactions from Stripe and bank exports.
Don't be me.
Common Mistakes I See First-Time Founders Make
After helping six different friends set up their businesses since 2023, I keep seeing the same handful of errors.
Here are the ones that cost real money:
- Paying $300 for an EIN. It's free directly from the IRS. Always.
- Forming an LLC in Delaware "for the tax benefits" when you operate entirely in California. You'll pay both Delaware fees and California's $800 minimum franchise tax. Form where you actually do business.
- Mixing personal and business expenses. This single mistake can pierce your LLC's liability shield in court.
- Filing the S-corp election too early. Under about $40k net profit, the payroll compliance overhead eats the tax savings.
- Forgetting the annual report. Texas, Delaware, California, and most other states will dissolve your LLC if you miss two consecutive filings.
- Using a free template Operating Agreement without reading it. Especially with co-founders. Spend $200 on a real one.
State-by-State LLC Filing Fees and Annual Reports
Where you form your LLC matters because the fees vary by an order of magnitude.
Here's a snapshot of common states for 2026, sourced from each Secretary of State's published fee schedule.
| State | LLC Filing Fee | Annual Report / Tax | Processing Time |
|---|---|---|---|
| Delaware | $110 | $300/year | 1–2 weeks standard |
| California | $70 | $800 minimum franchise tax | 5–10 business days |
| Texas | $300 | $0 (no income tax) | 3–5 business days |
| Florida | $125 | $138.75/year | 2–4 business days |
| New York | $200 | $25–$4,500 (income-based) | 7 business days |
| Wyoming | $100 | $60/year | 1–2 business days |
| Kentucky | $40 | $15/year | 1 business day |
| Massachusetts | $500 | $500/year | 5–7 business days |
The takeaway: form your LLC in the state where you actually live and work.
The "Delaware advantage" really only matters for companies raising venture capital, since VCs prefer Delaware C-corps for governance reasons.
For a single-member LLC running a Shopify store from your apartment, you'll save thousands by skipping the out-of-state filing.
Frequently Asked Questions
Q.
Can I get an EIN without an LLC?
A.
Yes.
Sole proprietors can apply for an EIN using their personal name and SSN through the IRS website at no cost.
It's actually recommended so you don't have to give out your SSN on W-9 forms to clients.
Q.
Do I need a new EIN if I convert my sole proprietorship to an LLC?
A.
Yes, in most cases.
The IRS treats the LLC as a new legal entity, so you'll apply for a fresh EIN even if you keep the same business activity and bank accounts.
There's no fee for the new EIN.
Q.
How long does it take to form an LLC in 2026?
A.
It depends on the state.
Kentucky and Wyoming approve LLCs in 1–2 business days, while California and New York can take 7–14 days.
Most states offer expedited 24-hour processing for an extra $50–$100.
Q.
Will an LLC actually protect my personal assets if I get sued?
A.
It can, but only if you maintain the legal separation.

Q.
Should I use LegalZoom or file my LLC myself?
A.
For a straightforward single-member LLC in your home state, filing directly with the Secretary of State takes about 20 minutes and saves $100–$300.
Services make more sense for multi-state operations or if you genuinely don't have time.
