Do You Need an Accountant When Starting a Limited Company? A Startup Guide

7 July 2026

Starting a limited company is an exciting milestone, but it also brings a new layer of financial and legal responsibilities that many first-time directors do not anticipate. From registering with HMRC to filing annual accounts with Companies House, the compliance obligations can quickly feel overwhelming. This guide explains what an accountant does for a new business and helps you decide whether you need one from day one.

The Compliance Obligations of a Limited Company

When you set up a limited company, you take on a range of statutory duties that do not apply to sole traders. These include:

Registering the company with Companies House and maintaining a registered office address
Registering for Corporation Tax with HMRC within three months of starting to trade
Preparing and filing annual accounts with Companies House
Submitting a Corporation Tax return to HMRC each year
Filing a confirmation statement with Companies House annually
Keeping accurate accounting records and maintaining statutory books

Missing deadlines or filing incorrect information can result in financial penalties and in serious cases can reflect poorly on you as a director. Having an accountant in place from the start ensures these obligations are met correctly and on time.

What Does an Accountant Do for a Startup?

Many new business owners assume that an accountant simply files their tax return at the end of the year. A good accountant provides ongoing support across every stage of your business journey. For startups, this typically includes:

Business structure advice. An accountant can help you decide whether a limited company is the right structure for your business or whether another arrangement might be more appropriate.
Tax efficient remuneration planning. Working out the most tax efficient combination of salary and dividends from day one can save you a significant amount of money over the course of a year.
Bookkeeping and accounting setup. Getting your bookkeeping right from the start avoids costly corrections later. An accountant can set you up on cloud accounting software and ensure your records are organised from the outset.
VAT registration advice. If your turnover is approaching the VAT threshold, or if voluntary registration makes sense for your business, an accountant can guide you through the options.
Year-end accounts and tax returns. Preparing and filing compliant accounts and Corporation Tax returns to meet Companies House and HMRC deadlines.
Business advisory support. As your business grows, an accountant can help you interpret your numbers, plan for the future and make informed decisions.

When Should You Hire an Accountant for Your New Business?

The ideal time to engage an accountant is before you start trading, or at the very latest as soon as your company is incorporated. Getting professional advice at the beginning means your company is structured correctly, your tax position is optimised from day one and you avoid the common mistakes that can prove costly to unravel later.

If you have already started trading without an accountant, it is never too late to bring one on board. At Affinity Associates Isaacs & Co, we regularly work with business owners who have been managing on their own and need help catching up or restructuring their affairs.

How Much Does a Startup Accountant Cost?

The cost of accountancy support for a new limited company varies depending on the services you need. A basic compliance only package covering year end accounts and Corporation Tax typically starts from around £100 per month. If you also need payroll, VAT returns, bookkeeping support and ongoing advisory access, fees will reflect the additional work involved.

At Affinity Associates Isaacs & Co, we offer fixed monthly fee packages tailored to new businesses so you have predictable costs and no surprises. We are transparent about what is included and always discuss our fees upfront.

What Should You Look for in an Accountant for a New Business?

Not all accountants are equally well suited to working with startups. When choosing an accountant for your new limited company, look for someone who:

Holds a recognised professional qualification such as ACCA or ACA
Has experience working with new businesses in your sector
Communicates clearly and is easy to get hold of
Offers proactive advice rather than simply reacting to deadlines
Uses modern cloud accounting software
Offers a fixed fee structure so you know exactly what you are paying
