The 7 Universal Steps to Register a One Person Company

Regardless of which country you are in, the registration process follows the same fundamental steps. The specific forms, portals, and fees differ, but the logic is identical everywhere.

01
Choose Your Legal Structure
Decide between a single-member LLC (US), OPC (India), Ltd (UK), or your country's equivalent. If you are unsure, read our comparison guide to understand the trade-offs between structures. For most solo entrepreneurs, the one person company structure (not sole proprietorship) is the right starting point.

02
Reserve Your Business Name
Check if your desired name is available using your country's business name registry. The name must be unique and not conflict with existing registered businesses. Most countries allow you to search and reserve names online. In the US, check your state's Secretary of State database. In India, use the RUN (Reserve Unique Name) service on the MCA portal. In the UK, search the Companies House register.
Naming rules (common across countries): Must include entity suffix (LLC, OPC Pvt Ltd, Ltd). Cannot be identical or deceptively similar to existing companies. Cannot contain restricted words (bank, insurance, government) without approval.
⏱ 1–3 days 💰 $0–$30 🌐 Online
03
Prepare Required Documents
Gather your identification and draft the necessary formation documents. The exact requirements vary by country (see country-specific sections below), but you will generally need personal ID, proof of address, and formation documents specific to your entity type.
⏱ 1–2 days 💰 $0–$200 (if using a lawyer)
04
File Registration with Government
Submit your formation documents to the relevant government body. In the US, file Articles of Organization with your state's Secretary of State. In India, submit the SPICe+ form to the Ministry of Corporate Affairs (MCA). In the UK, file an application with Companies House. Most countries offer online filing for faster processing.
⏱ 1–10 days (processing) 💰 $12–$500 (gov fees) 🌐 Online
05
Get Your Tax Identification Number
Once your company is registered, apply for a tax ID. In the US, apply for an EIN (Employer Identification Number) from the IRS — it is free and issued instantly online. In India, PAN and TAN are auto-generated during SPICe+ registration. In the UK, register for Corporation Tax with HMRC to receive your UTR (Unique Taxpayer Reference) within 10 days.
⏱ Instant – 10 days 💰 Free 🌐 Online
06
Open a Business Bank Account
Keeping business and personal finances separate is essential for maintaining your limited liability protection. Bring your Certificate of Incorporation, tax ID, and personal identification to open a business bank account. Many banks also support online applications for business accounts. Consider choosing a bank with low fees, good online banking, and integration with accounting software.
⏱ 1–5 days 💰 $0–$50 (initial deposit)
07
Set Up Your Compliance Calendar
Mark all annual filing deadlines, tax return due dates, and renewal requirements in your calendar from day one. Missing deadlines can result in penalties, loss of good standing, or even dissolution of your company. Set reminders at least 30 days before each deadline. This single habit will save you from the most common compliance mistakes that trip up new business owners.

What to Do After Registration

Receiving your Certificate of Incorporation is just the beginning. Here are the essential post-registration tasks to complete within your first 30 days.

🏦
Open Business Bank Account
Separate your finances immediately. Bring your incorporation certificate, tax ID, and personal ID.
📊
Set Up Accounting
Choose accounting software (Wave, QuickBooks, Xero). Track every expense from day one — this saves you during tax season.
📜
Get Business Licenses
Check if your industry or location requires specific permits. Many online businesses need minimal licenses.
🛡️
Consider Business Insurance
General liability insurance protects against client claims. Professional liability (E&O) is important for consultants and service providers.
📅
Create Compliance Calendar
Mark annual report deadlines, tax filing dates, and license renewals. Set reminders 30 days before each due date.
🌐
Build Your Online Presence
Register your domain, set up a professional website, and create business profiles on relevant platforms.
⚠️ Common First-Year Mistakes

Mixing personal and business money — This can destroy your limited liability. Use separate accounts for everything. Missing annual filing deadlines — Late fees add up fast, and your company can lose its good standing. Not keeping receipts — Every business expense is a potential tax deduction, but only if you have documentation.
