How to Start a Business: The Financial Setup Checklist

Financial Foundations First

The excitement of starting a new business makes it tempting to focus entirely on the product, the customers, and the brand - and to treat financial setup as paperwork to be dealt with later. This is a common mistake that creates compounding problems. A business with proper financial infrastructure from day one has accurate records, complies with tax obligations, builds credit, and makes better decisions. A business that defers financial setup often finds itself scrambling to reconstruct records for a tax return, facing penalties for missed registrations, or unable to understand its own financial performance.

This checklist covers everything you need to set up the financial side of a new business correctly. Work through it systematically - ideally before you make your first sale.

Legal Structure and Registration

Choose your legal structure: sole trader, partnership, limited company, or LLP. Each has different tax, liability, and compliance implications - consult an accountant if you're unsure. Related reading: sole trader vs. limited company: which is right for you?
Register with the appropriate authority: sole traders register with HMRC for Self Assessment; limited companies register with Companies House
Apply for a VAT number if your taxable turnover exceeds or will exceed £90,000 (2024/25 threshold), or consider voluntary registration if clients can reclaim VAT
Register as an employer with HMRC if you'll be hiring employees from day one

Banking and Cash Infrastructure

Open a dedicated business bank account. Never use a personal account for business transactions
Set up a business savings account for tax reserves - transfer a percentage of every payment received as you go
Apply for a business credit card for expenses that benefit from card protections or rewards
Set up your payment processing: how will clients pay you? Bank transfer, card payment, PayPal, Stripe?

Accounting and Bookkeeping

Choose and set up cloud accounting software - this is the financial hub of your business
Connect your bank account via open banking for automatic transaction import
Configure your chart of accounts for your specific business type
Set up your invoice template with your business details, payment terms, and bank details
Establish an expense capture system - app, email folder, or physical folder - and commit to capturing receipts in real time
Set a recurring weekly bookkeeping appointment in your calendar

Tax Obligations to Register For

Sole trader: register for Self Assessment by 5 October following your first tax year of trading
Limited company: register for corporation tax with HMRC within three months of starting to trade
Register for VAT if applicable (see above)
Register as an employer if hiring from day one
Understand your tax payment deadlines before they arrive - not after

Insurance and Protection

Public liability insurance (essential if clients visit your premises or you visit theirs)
Professional indemnity insurance (essential for service businesses and consultants)
Employers' liability insurance (legally required if you have employees)
Contents and equipment insurance if you have significant physical assets
