What Does an Accountant Do When You First Start a Company?

Starting a new business is exciting, but it also comes with a long list of responsibilities. One of the best moves you can make early on is bringing an accountant on board. But what exactly does an accountant do when you first start a company?

In this blog post, we’ll walk through the key ways an accountant supports your business from day one, and why working with a firm like Crossley & Davis helps set you up for long-term success.

1. Helping You Choose the Right Business Structure

One of the first decisions you’ll make is whether to trade as a:

Sole trader
Limited company (Ltd)
Partnership or LLP

An accountant can explain the pros and cons of each based on your goals, income, and risk level – and help you choose the most tax-efficient option.

2. Registering Your Business with Companies House and HMRC

If you’re forming a limited company, your accountant can:

Handle the company formation process
Register your business with HMRC for Corporation Tax
Set up VAT or PAYE if needed

From Autumn 2025, all directors and PSCs will also need to verify their identity with Companies House. An accountant can take care of this for you.

3. Setting Up Accounting Systems and Software

Getting the right systems in place early helps you stay compliant and organised. Your accountant can:

Recommend and set up cloud accounting software (e.g. Xero, Quickbooks)
Create a chart of accounts tailored to your business
Set up tools for expenses, invoicing, and reporting

4. Making Sure You’re Compliant From Day One

Accountants ensure you:

Meet Companies House deadlines
Understand your tax obligations
Have a record-keeping system that meets HMRC requirements

They also help you avoid common new-business mistakes that lead to penalties.

5. Providing Tax Planning Advice

Starting with smart tax strategies can save you money from year one. Your accountant will advise on:

Allowable expenses
Whether to register for VAT voluntarily
The most tax-efficient way to pay yourself as a director

6. Acting as Your Trusted Business Advisor

Your accountant isn’t just there to file returns – they’re a sounding board and strategic partner.
