In the complex world of business finance, few things are as vital — and as misunderstood — as Value Added Tax (VAT). For many UK business owners, keeping up with changing VAT regulations, filing returns accurately, and staying compliant with HMRC requirements can be overwhelming. That’s where VAT accountants come in.
A professional VAT accountant doesn’t just handle your tax paperwork; they ensure your business operates smoothly, remains compliant, and avoids costly penalties. In this guide, we’ll explain what VAT accountants do, why they matter for businesses of all sizes, and how working with a trusted provider like The Infinity Group can make your VAT process easier, faster, and fully HMRC-compliant.
What Is VAT and Why It Matters for UK Businesses
Value Added Tax (VAT) is a consumption tax applied to most goods and services sold in the UK. It’s collected by businesses on behalf of HMRC — which means if you’re VAT-registered, you’re responsible for charging VAT on your sales and paying it to the government.
As of 2025, most UK businesses with a taxable turnover above £90,000 must register for VAT. Even smaller businesses below this threshold may choose to register voluntarily to reclaim VAT on expenses.
But VAT isn’t just a matter of adding 20% to your prices — it involves understanding the right VAT scheme for your business, filing returns correctly, and ensuring that every transaction complies with HMRC regulations. This is where VAT accountants prove invaluable.
What Does a VAT Accountant Do?
A VAT accountant provides expert support to help businesses manage all aspects of VAT — from registration to filing and compliance. Their role includes both technical accounting work and strategic tax advice.
Let’s explore the key responsibilities of a VAT accountant in more detail:
1. VAT Registration and Deregistration
VAT accountants help businesses determine whether they need to register for VAT and guide them through the registration process with HMRC. They also advise when and how to deregister, such as when turnover falls below the threshold or during company restructuring.
Example:
A small construction company crossing the VAT threshold for the first time may not know how to handle registration. A VAT accountant ensures timely registration, preventing HMRC fines and backdated liabilities.
2. Preparing and Submitting VAT Returns
This is one of the most crucial responsibilities. VAT accountants prepare accurate VAT returns based on your business transactions and submit them through HMRC’s Making Tax Digital (MTD) platform.
They ensure all figures are correct, deadlines are met, and input and output VAT are reconciled properly.
Example:
A retail business might sell hundreds of items daily. A VAT accountant ensures the VAT portion of each sale and purchase is accurately reflected in the quarterly return, eliminating risk of overpayment or underpayment.
3. Advising on VAT Schemes
There isn’t a one-size-fits-all VAT system. HMRC offers various VAT schemes — including the Flat Rate Scheme, Cash Accounting Scheme, and Annual Accounting Scheme — each designed to suit different business types and turnover levels.
VAT accountants evaluate your operations and help select the most tax-efficient scheme.
For example:
- Flat Rate Scheme is often suitable for small businesses with low expenses.
- Cash Accounting Scheme helps manage cash flow by paying VAT only when customers pay you.
Example:
A freelance IT consultant could save time and money by adopting the Flat Rate Scheme — advice a VAT accountant would provide after reviewing income and expense patterns.
4. Handling VAT Audits and HMRC Inquiries
Even well-run businesses may face HMRC VAT inspections. A VAT accountant acts as your representative, ensuring all documentation is in order and responding professionally to HMRC inquiries.
Example:
If HMRC questions discrepancies between sales invoices and VAT returns, your accountant can provide explanations, evidence, and ensure compliance is demonstrated — reducing stress and risk.
5. VAT Planning and Compliance
Beyond simple filing, VAT accountants offer strategic planning — identifying opportunities for legitimate VAT recovery and advising on potential risks. They keep your business updated on changes in VAT law, such as post-Brexit trade rules or rate adjustments.
This proactive support helps businesses avoid errors that could lead to HMRC penalties.
Example:
A UK-based import/export company may face complex VAT issues post-Brexit. A VAT accountant ensures compliance with cross-border VAT rules and customs documentation.
6. Reclaiming VAT on Business Expenses
A vital part of VAT management is reclaiming the VAT you’ve paid on eligible purchases — from office supplies to travel expenses. VAT accountants ensure these claims are accurate, properly documented, and within HMRC’s rules.
Example:
A construction firm might purchase materials and tools regularly. A VAT accountant ensures input VAT is claimed correctly, reducing the company’s overall tax burden.
7. Providing Ongoing Advice and Support
The role of a VAT accountant doesn’t end after filing returns. They provide continuous support, helping you understand changes in legislation, plan for audits, and manage tax efficiently throughout the year.
This long-term guidance can be the difference between smooth financial operations and costly compliance errors.
Why VAT Accountants Matter More Than Ever in 2025
The UK tax landscape has evolved dramatically — especially with Making Tax Digital (MTD) and increased HMRC scrutiny on VAT compliance. Many small and medium-sized businesses (SMEs) are finding it harder to keep up with digital requirements, filing deadlines, and evolving tax schemes.
Here’s why VAT accountants are more important than ever:
1. Ensuring Full HMRC Compliance
HMRC penalties for incorrect VAT returns can be severe — up to 100% of the unpaid tax. VAT accountants help prevent these costly mistakes by ensuring all filings are accurate, timely, and fully compliant.
2. Saving Time and Reducing Stress
Manual VAT calculations and filings can consume valuable time better spent growing your business. Outsourcing VAT tasks to professionals saves hours of administrative effort.
3. Maximising VAT Recovery
VAT accountants know which expenses are eligible for VAT reclaim — often identifying tax savings that business owners overlook.
4. Avoiding Common VAT Pitfalls
Incorrectly charging VAT, missing deadlines, or applying the wrong VAT rate are frequent issues for small businesses. VAT accountants eliminate these risks.
5. Supporting Digital Tax Transformation
With MTD mandatory for nearly all VAT-registered businesses, VAT accountants ensure your accounting systems are fully integrated with HMRC’s digital platforms.
