What to do first in Connecticut
Use this order alongside the detailed checklist below. Work on independent tasks together, but confirm approvals before committing money or opening.
2. Before signing a lease
Describe the exact activity to planning or zoning and the industry regulator. Ask about permitted use, occupancy, inspections and approval timing before committing to premises or renovations.
3. Before taking payments
Complete applicable entity, name, tax and operating registrations. Confirm taxability, required customer documents and insurance. Test payments, receipts and customer follow-up before launch.
4. Before hiring
Resolve worker classification, employer accounts, payroll, new-hire reporting and coverage. Check industry staffing and background-check requirements before anyone starts.

Build a launch checklist for your business.
Choose your work, location and hiring plans. Review the full sequence below as well; this tool cannot identify every permit.

Your Connecticut launch sequence.
Use this sequence alongside the personalized checklist. Check the rules for your structure, activities and location.
Test demand and choose a structure
Define customers, prices, startup cash and recurring expenses. Compare ownership, liability and tax treatment before buying filing services.
Register the business and name
Use Business.CT.gov for LLC or corporation formation and out-of-state qualification. Sole proprietors follow a different route. A trade name is filed with the local town clerk; follow current town and entity-specific instructions.
Review federal tax identification
Apply directly with the IRS for an EIN when needed. Keep federal, entity and state tax account numbers separate.
Set up tax accounts
Register applicable tax accounts with Connecticut DRS through myconneCT. Review sales and use tax, taxable services and employer withholding. Formation, tax registration and local permits are separate steps.
Check industry and local permission
List all activities and locations. Resolve occupational credentials, zoning, occupancy, health, fire and sign approvals before opening.
Prepare coverage and hiring
With limited exceptions, Connecticut employers must carry workers’ compensation for their employees. Check owner, member and partnership elections and the actual worker relationship with the Workers’ Compensation Commission.
Calendar ongoing compliance
Check the Business.CT.gov annual-report instructions for your entity, first filing year, deadline and fee. Keep the registered agent, principal address and required owner or manager information current.
Keep state and local steps separate.
Trade-name certificates go to the local town clerk, while applicable state tax accounts are registered through myconneCT. Neither filing replaces occupational or local operating approvals.

View guidance →Online and interstate sales

View guidance →Separate business records

View guidance →Connecticut launch guide
Check the work and the address.
Construction and trade services
Check the appropriate Connecticut occupational regulator for contractor, builder and specialty-trade credentials. Confirm project permits and inspections with the municipality before bidding or beginning regulated work.
View guidance →Food, home kitchens and farms
Identify the food or agriculture regulator for your products and preparation site. Ask about cottage-food eligibility, market sales, processing and environmental permissions.
View guidance →Beauty, professional and automotive work
Check practitioner credentials, business or establishment approvals and regulated products. Describe every offered service to the relevant regulator.
View guidance →Home, shop, mobile or online
Ask local authorities about zoning, customer visits, storage, occupancy, signs, vending and events. Check the operating base even when customers buy online.

Review required coverage and business risks.
Workers’ compensation
With limited exceptions, Connecticut employers must carry workers’ compensation for their employees. Check owner, member and partnership elections and the actual worker relationship with the Workers’ Compensation Commission.
View guidance →Liability, property and vehicles

View guidance →Connecticut launch guide
Prepare before anyone starts work.
Employer accounts and payroll
Check Connecticut unemployment insurance, applicable withholding, new-hire reporting, wage and leave rules and required postings before hiring. Entity formation alone does not establish every employer account. Confirm employee versus contractor status with the relevant agencies.
View guidance →Employees or contractors
Review the actual working relationship before treating someone as an independent contractor. A written agreement or 1099 does not determine status; check duties with each relevant agency.
View guidance →Connecticut launch guide
Keep filings and renewals organized.
Entity-specific duties
Check the Business.CT.gov annual-report instructions for your entity, first filing year, deadline and fee. Keep the registered agent, principal address and required owner or manager information current.
View guidance →Other recurring obligations
Track tax returns, occupational and local licenses, coverage and business-record changes. Close or update accounts properly when work, ownership or locations change.

Find your city and county government’s official website. Look for planning or zoning, business licensing, building inspections and the tax or revenue office. Describe what you will actually do, including home visits, deliveries, storage and online fulfillment.
Ask these questions
- Is this activity permitted at this address?
- Which licenses, tax accounts and inspections apply?
- Do home occupation, signs, parking or customer visits change the rules?
- What must be approved before opening, and what renews later?
- Can you send the requirements and fee schedule in writing?
For a daycare, ask the child-care regulator before adapting a property. For a contractor, ask the trade board and the local building office.
