Accounting Checklist for New Business Owners in London

Starting a new business is an exciting venture, but it comes with a range of responsibilities - one of the most important being your accounting and financial setup. Whether you’re launching a limited company, sole proprietorship, or partnership in the UK, getting your accounting in order from day one is crucial for compliance, cash flow, and long-term success. If you’re a new business owner in London or the surrounding areas, this accounting checklist will help you stay organised and on top of your financial obligations.

1. Register Your Business with HMRC or Companies House

   If you’re setting up as a limited company, you’ll need to register with Companies House and ensure your company complies with filing obligations such as annual accounts and confirmation statements. Sole traders and partnerships must register with HM Revenue & Customs (HMRC) for self-assessment.

2. Open a Dedicated Business Bank Account

   A separate business bank account is essential for maintaining clear financial records. It simplifies your bookkeeping, helps track deductible expenses, and is a legal requirement for limited companies.

3. Choose the Right Accounting Software

   Cloud-based accounting platforms like Xero, QuickBooks, and FreeAgent allow you to manage your accounts efficiently and in real time. These tools help track expenses, create invoices, and generate financial reports.

4. Understand VAT Obligations

   If your business’s taxable turnover exceeds £90,000, you must register for Value Added Tax (VAT). Even if you're below the threshold, voluntary VAT registration could offer advantages depending on your customer base.

5. Set Up a System for Bookkeeping and Expense Tracking

   Accurate bookkeeping ensures that all income and expenses are recorded properly. Keep digital or physical receipts and consider hiring a professional to maintain your records.

6. Know Your Tax Deadlines

   Missing deadlines can result in penalties. Be aware of key dates such as the 31st January self-assessment deadline, corporation tax deadlines, and VAT return dates.

7. Plan for Payroll and PAYE (if hiring staff)

   If you plan to employ staff, you’ll need to register as an employer with HMRC and set up Pay As You Earn (PAYE). This system deducts income tax and National Insurance from employee wages.

8. Work with a Trusted Local Accountant

   Partnering with a proactive and experienced accountant can save you time, reduce your tax bill, and ensure you stay compliant. An accountant can also offer business advice, financial planning, and growth support.
