Online Accountant UK: How to Choose and Work With One

For 2026/27, Corporation Tax is generally 19% on profits up to £50,000 and 25% on profits over £250,000, with marginal relief between those limits. The thresholds can be affected by associated companies. The VAT registration threshold is £90,000 of taxable turnover in a rolling 12-month period; the deregistration threshold is £88,000.

Choosing an online accountant in the UK is about more than finding a firm that uses digital tools. You are choosing a working relationship: who handles your company’s accounts, how questions get answered, what you need to provide and what happens when the work is finished, or when you decide to move on.

If you have been searching for an accountant near me, an online service may still suit your company. The key is to compare the people, terms and processes behind the website, not just the location or headline promise.

What matters when choosing an online accountant?

Start with the practical details that will affect your day-to-day experience.

Who will actually do the work?

Ask who will prepare your bookkeeping, annual accounts and Corporation Tax work, and who will review it. Find out whether you will have a named contact, access to a wider team, or both. Ask who covers your work when your usual contact is away.

A clear answer gives you a sense of responsibility and continuity. If the firm cannot explain who owns your file or how queries are routed, it may be difficult to get help when something needs attention.

How and when will they respond?

Ask how you should contact the team and what response time you can normally expect. Find out how urgent matters, such as a payroll issue or an upcoming filing, are escalated, and who monitors messages when your contact is unavailable.

A realistic, written service standard is more useful than a general promise to be responsive. Check whether it appears in your engagement letter.

Does the software fit your company?

Ask which accounting and document-sharing systems the firm uses, whether they can work with your current setup, and whether the software cost is included in the agreed service.

Make sure you understand how to submit documents, who can access them and how you can retrieve your company records if you leave. Digital tools can make sharing information easier, but they do not replace clear responsibilities or careful reviews.

What does the fee include?

Limited-company accounting and tax support starts at £85pm+. The work included can vary, so ask for a written explanation of what the quoted service covers. For example, clarify whether it includes bookkeeping, annual accounts, Corporation Tax work, VAT returns, payroll, confirmation statement support and routine advice, or whether any of these are separate.

Ask what could lead to additional work and how the firm will tell you about it before proceeding. The aim is not to assume every service must be included; it is to know where your responsibilities and the accountant’s responsibilities begin and end.

How will your data be protected, and how can you leave?

Ask how the firm shares and stores documents, who is authorised to access your records, and how you can get copies of your information. Find out what happens to access and records if the engagement ends, including whether the firm will support a handover and how any work in progress is handled.

A clear exit process is part of a sound working arrangement. You should understand what records you can take with you and how to avoid disruption to upcoming filings.

Questions to ask before signing

To compare firms fairly, ask each one the same questions and note the answers:

• Who will prepare and review my company’s work?
• Will I have a named contact, and who covers when they are away?
• How should I send records and ask questions?
• What response time should I expect, and how are urgent issues handled?
• Which services are included in the engagement, and what is excluded?
• What information must I provide, and by when?
• How are deadlines tracked and reminders sent?
• How are records stored, shared and returned if I leave?
• How will extra work or changes to the agreed scope be discussed?
• What qualifications, professional standing, AML supervision and insurance does the firm have?

Ask the firm to explain its answers in plain English. You should be able to compare the proposals without guessing what phrases such as “full support” or “proactive service” mean in practice.

How the relationship works after appointment

A good online relationship has a routine that both sides understand.

Onboarding

At the start, the accountant will usually need to understand your company, its activities and its existing records. You may be asked for company documents, previous accounts and tax filings, bookkeeping information, payroll details and relevant tax references. The firm should explain what it needs, how to provide it securely and what happens next.

Agree who is responsible for keeping records current. If you are expected to upload invoices or categorise transactions, make sure you know how often to do that and where questions should go.

Regular records and queries

Set a regular rhythm for sending documents and responding to questions. The accountant may ask you to clarify transactions, provide missing records or review reports. Prompt answers help keep the work moving; in return, you should know when to expect updates and how the team will flag an issue that could affect your company.

Reviewing and approving filings

Before accounts or tax returns are submitted, the accountant should explain what you are being asked to approve and how to raise questions. Read the figures and ask about anything you do not understand. An online approval process can be convenient, but it does not remove the need to check the information or agree the final submission.

Managing deadlines

Agree who monitors each relevant deadline, when the accountant needs information from you and what happens if records arrive late. A filing date is not always the same as a tax payment date, so ask the firm to distinguish between them.

The 2026/27 UK small-business tax deadlines calendar can help you see the dates to discuss with an accountant. Your own deadlines will depend on your company and tax position.

What good, and bad, looks like online

A healthy relationship is personal even when it is remote. Good signs include a named contact or clearly accountable team, realistic response expectations, proactive reminders, clear explanations and written agreement about what is included.

Warning signs include messages disappearing into an unmonitored helpdesk, repeated chasing for basic answers, important deadlines being raised at the last minute, or extra charges appearing without a clear explanation. Vague scope can also lead to scope creep: you may think a task is included while the firm considers it additional work.

Pay attention to how the firm communicates before you appoint it. If you cannot get a straightforward answer to a reasonable question during the selection process, consider how that may feel when you are dealing with a time-sensitive issue.

When an online accountant may not be the right fit

Online accounting is not right for every company. You may want a more hands-on service if your records need substantial clean-up before routine work can begin, or if your company is part of a complex group with several entities and interconnected transactions. Ask prospective firms directly whether they have the experience and capacity for that work.

You may also prefer in-person meetings, especially if that is important to how you discuss sensitive or complicated decisions. A local or hybrid arrangement may suit you better. The point is to choose a way of working that lets you communicate clearly and understand what is happening in your company’s accounts.

Check the firm before appointing

In the UK, the title “accountant” is not protected. Ask about the qualifications and professional-body membership of the people responsible for your work, and verify the details directly with the relevant body. Also ask who supervises the firm for anti-money-laundering purposes and what professional indemnity cover it holds. Confirm that the supervision and cover are appropriate for the services you are engaging.

We check the credentials and regulatory standing of our accountants before we introduce them. Every accountant we work with is vetted for their qualifications, membership of a registered body for public practice, and AML registration, and your details are shared only with a vetted few who fit your brief. Always confirm a firm's registration, supervision and cover directly before you appoint them.

If you are a company director who also needs help with a personal tax return, use our Self Assessment registration form. A Self Assessment tax return is £300 inc VAT.

Find an online accountant who fits your company

The right online accountant should make responsibilities clear, explain the service in a way you understand and help you keep work moving throughout the year. Compare the contact arrangements, software fit, scope, data access and exit terms, not just the first impression.
