The Complete Post-LLC Setup Checklist (2026)
Everything you need to set up after forming your LLC, with real costs and timelines for banking, accounting, insurance, payroll, and more.
In This Article
A full post-LLC business setup runs $500 to $5,000 in your first year. Start with your free EIN from the IRS, then open a $0/month business bank account, connect accounting software, and get general liability insurance. Most founders can complete the essentials in 1 to 2 weeks.
Your LLC is filed. Now what? The real work of setting up a business starts after formation, and it typically costs between $500 and $5,000 in your first year depending on your business type. You need an EIN (free, 10 minutes), a business bank account ($0/month at Mercury or Bluevine), accounting software ($0 to $38/month), and at minimum a general liability insurance policy (median $45/month).
This checklist walks you through every post-formation setup task in order, with the exact cost, timeline, and link to complete each one. Skip a step, and you risk IRS penalties, uninsured lawsuits, or commingled funds that blow up your LLC's liability protection.
Setting up a business after LLC formation follows a predictable sequence. You start with your EIN, move to banking, then layer on accounting, insurance, a web presence, and (if needed) payroll. Most founders can complete the critical steps in 1 to 2 weeks and spend under $1,000 in the process.
The order matters. You cannot open a business bank account without an EIN. You cannot set up payroll without a bank account. And you should not accept your first payment without general liability insurance in place. Follow this checklist in order and you will avoid the most common (and most expensive) first-year mistakes.
- Phase 1 (Day 1): EIN + formation documents
- Phase 2 (Day 1-3): Business bank account
- Phase 3 (Week 1): Accounting software
- Phase 4 (Week 1-2): Business insurance
- Phase 5 (Week 2-3): Website + Google Business Profile
- Phase 6 (When hiring): Payroll setup
- Phase 7 (Ongoing): Compliance, licenses, taxes
For the complete step-by-step on any single task, jump to our dedicated guides: how to open a business bank account, how to set up small business accounting, or how to set up payroll.
Phase-by-Phase Breakdown
- 1
Get Your EIN and Foundational Documents
Your EIN is the gateway to everything else. Banks, payroll providers, and the IRS all require it. Apply for free at IRS.gov and receive your number instantly online.
- Apply for a free EIN at IRS.gov (10 minutes)
- Draft or finalize your LLC operating agreement
- Order a certified copy of your Articles of Organization from your state
30 minutes to 1 day $0 to $50 - 2
Open a Business Bank Account
Separating business and personal finances is the single most important thing you do after formation. A dedicated bank account protects your LLC's liability shield and simplifies taxes. Mercury and Bluevine both offer $0/month accounts with no minimum balance.
- Compare free business checking options (Mercury, Bluevine, Relay)
- Gather your EIN letter, Articles of Organization, and government ID
- Open your account online in under 30 minutes
1 to 3 business days $0 to $30/month - 3
Set Up Accounting and Bookkeeping
If you do nothing else, connect your bank account to accounting software so every transaction is tracked from day one. Wave is free. QuickBooks Simple Start runs $38/month as of 2026. Waiting until tax season to organize your books costs you deductions and sanity.
- Choose accounting software (Wave free, QuickBooks $38/mo, Xero $25/mo)
- Connect your business bank account and credit card feeds
- Set up your chart of accounts and tax categories
1 to 2 hours $0 to $38/month - 4
Get Business Insurance
General liability insurance is the baseline protection every business needs. At a median cost of $45/month, it covers third-party injuries, property damage, and advertising claims up to $1M per occurrence. Some clients and landlords require proof of insurance before you can start work.
- Get quotes from at least 3 providers (Next, Hiscox, The Hartford)
- Purchase general liability insurance ($45/month median)
- Add professional liability (E&O) if you provide advice or consulting
1 to 3 hours $500 to $3,000/year - 5
Build Your Business Website and Digital Presence
Your domain name costs about $10 to $15/year and a basic website runs $200 to $1,000/year on platforms like Squarespace or WordPress. Claim your Google Business Profile for free to appear in local search results and on Google Maps.
- Register your domain name ($10 to $15/year)
- Build a basic website with Squarespace or WordPress ($16 to $45/month)
- Claim your free Google Business Profile
2 to 8 hours $200 to $1,000/year - 6
Set Up Payroll (If You Have Employees)
If you hire employees, you need payroll software to handle tax withholding, direct deposits, and W-2 filing. Gusto starts at $49/month plus $6 per employee as of 2026. Skip this phase if you are a solo founder with no employees or contractors.
- Choose a payroll provider (Gusto, QuickBooks Payroll, OnPay)
- Register for state employer tax accounts
- Set up employee onboarding and direct deposit
1 to 3 hours $49 to $200+/month - 7
Handle Ongoing Compliance and Growth Tools
Your LLC has annual obligations including state annual reports, franchise taxes, and registered agent fees. Missing a filing deadline can cost you your good standing status or trigger penalties of $50 to $500+. Set calendar reminders now.
- Confirm your registered agent is active ($99 to $300/year)
- Set reminders for your state annual report deadline
- Research local business licenses and permits for your industry
1 to 2 hours $99 to $500/year
Here is a realistic year-one budget for a typical small business, broken down by category. Your actual costs will vary based on your business type, state, and whether you hire employees.
| Category | Low Estimate (Annual) | Mid Estimate (Annual) | High Estimate (Annual) |
|---|---|---|---|
| EIN Application | $0 | $0 | $0 |
| Business Bank Account | $0 | $0 | $360 ($30/mo) |
| Accounting Software | $0 (Wave) | $456 (QuickBooks $38/mo) | $600 ($50/mo) |
| Business Insurance (GL) | $265 | $540 | $3,030 |
| Registered Agent | $99 | $150 | $300 |
| Website (domain + hosting/builder) | $200 | $400 | $1,000 |
| Payroll Software | $0 (no employees) | $660 (Gusto $55/mo) | $2,400 ($200/mo) |
| Business Licenses/Permits | $50 | $200 | $500 |
| Legal Tools (contract templates, etc.) | $0 | $100 | $200 |
| Year-1 Total | $614 | $2,506 | $8,390 |
A freelancer or consultant with no employees and free software can get fully set up for under $700 in year one. A brick-and-mortar store with employees, higher insurance needs, and a more robust website should budget $3,000 to $8,000+.
The biggest variable is payroll. If you have no employees, you save $660 to $2,400/year immediately. The second biggest variable is insurance; a home-based consultant pays far less than a restaurant or construction company.

These are the mistakes that cost real money. Avoid all seven and you will be ahead of 90% of new business owners.
1. Mixing Personal and Business Finances
Using your personal checking account for business transactions is the fastest way to "pierce the corporate veil" and lose your LLC's liability protection. If you are ever sued, a court can hold you personally responsible for business debts if your finances are commingled. Open a business bank account on day one.
2. Skipping Business Insurance
A single slip-and-fall claim costs an average of $45,000. General liability insurance at $45/month covers up to $1 million per occurrence. Going uninsured is not saving money; it is gambling your entire business on zero accidents.
3. Paying for a Free EIN
Third-party websites charge $50 to $200+ to file an EIN application that is completely free on IRS.gov. The IRS itself warns against these sites. You receive your EIN instantly when you apply directly.
4. Ignoring Quarterly Estimated Taxes
As an LLC owner, you owe self-employment tax of 15.3% on net income plus federal income tax. If you do not make quarterly estimated payments, the IRS charges an underpayment penalty. Set up payments through EFTPS immediately after you start earning revenue.
5. Choosing Accounting Software Too Late
Every month you operate without proper bookkeeping costs you 2 to 5 hours of catch-up work at tax time. At a bookkeeper's rate of $40 to $60/hour, that is $80 to $300 in wasted time per month. Set up Wave (free) or QuickBooks before your first transaction.
6. Missing Your State Annual Report
Most states require an annual or biennial report for your LLC. The filing fee ranges from $0 to $300, but missing the deadline can result in penalties of $50 to $500+ and eventually administrative dissolution of your LLC. Set a calendar reminder the day you form your company.
7. Skimping on Your Registered Agent
If your registered agent misses a lawsuit notification, a court can enter a default judgment against your business. That means you lose the case without ever getting a chance to defend yourself. Professional registered agent services cost $99 to $300/year. That is cheap insurance against a potentially catastrophic outcome. Compare options in our guide to best registered agent services.
Frequently Asked Questions
A basic post-LLC setup costs $500 to $1,500 for a solo freelancer and $3,000 to $8,000+ for a brick-and-mortar business with employees. The biggest line items are insurance ($265 to $3,000/year), payroll software ($0 to $2,400/year), and your website ($200 to $1,000/year). Banking and your EIN are free.
Apply for your free EIN at IRS.gov. It takes 10 minutes, costs $0, and you need it before you can open a bank account, set up payroll, or file taxes. Have your LLC's legal name and your SSN ready before you start the application.
Yes. Commingling personal and business funds can eliminate your LLC's liability protection. If a court finds your finances are not separated, you could be held personally liable for business debts. Mercury, Bluevine, and Relay all offer $0/month business checking accounts. See our full guide on how to open a business bank account.
At minimum, get general liability insurance at a median cost of $45/month. If you provide professional advice, add errors and omissions (E&O) insurance. If you hire employees, most states require workers' compensation. If you have a physical location, consider a Business Owner's Policy (BOP) that bundles GL with commercial property coverage at about $83/month.
Yes. Wave's Starter plan offers free accounting, invoicing, and receipt scanning with no transaction limits. The paid Pro plan costs $16 to $19/month and adds automated bank transaction imports and advanced features. Wave makes money through payment processing fees (2.9% + $0.60 per transaction) and its optional payroll service.
Most founders complete the core setup (EIN, bank account, accounting, insurance) in 3 to 5 business days. Adding a website takes another 2 to 8 hours. Payroll setup takes 1 to 3 hours but requires your state employer tax registration, which can take 1 to 4 weeks depending on the state.
If you have no employees and pay yourself through owner's draws, you do not need payroll software. You will pay self-employment tax when you file your annual return. If you elect S Corp taxation for your LLC (which makes sense for many businesses earning over $80,000 to $100,000), you must put yourself on payroll. See our LLC vs S Corp tax comparison for the math.
