VAT Services Archives - Unison Globus

If you’re a UK accountant looking to outsource VAT services, then Unison Globus UK can help you reduce costs, improve turnaround times, and scale even during the busiest periods.

Many UK accountants feel VAT accounting represents one of the more complex services to deliver. With the risk of fines and penalties for late returns, and changes in UK and EU regulations affecting even the smallest businesses, many accountants decide to deliver VAT work using only experienced tax professionals.

However, when the tasks involved in preparing a VAT return are broken down, many parts can be outsourced easily, freeing up experienced in-house resources to focus on more complex VAT advisory work. Common tasks outsourced by UK accountants include:

Bookkeeping and transaction coding
VAT return preparation
VAT reconciliations
Updating purchase and sales ledgers
EU and international VAT accounting
Making Tax Digital (MTD) submissions
VAT registration and deregistration
Responding to routine HMRC correspondence.

Available outsourcing models

Regardless of the size of practice seeking to outsource work, there are a number of options available.

Practices with high number of similar clients often decide to employ a full-time qualified professional based offshore. The individual is an extension of the onshore team and works directly to UK management. Where workload is harder to predict, some practices decide an ad-hoc (‘pay as you go’) type resource works best for them. This means resources can be scaled up when demand is high (at quarter end for example) and scaled down when demand is not so high.

Accountants can test the outsourcing process with a small amount of work, such as digital bookkeeping or VAT return preparation. Outcomes can be evaluated for quality, technical accuracy, and turnaround against performance consistent with in-house targets.

Many offshore suppliers, including Unison Globus UK, offer a free-trial period, where accountants can test the service before entering into a contract.

One Unison Globus UK customer is Alan Woods, the founder and owner of Woods Squared, who says:

“I can understand why the prospect of overseas outsourcing feels daunting – we were certainly cautious at first, but by investing in the relationship and finding the right partner, we’re now so much more agile as a practice.”

For any accountants not convinced, using a pay-as-you-go model can be a really good way of testing the waters or dipping a toe into exploring how the right outsourcing partner could support your firm, both to alleviate immediate demand and to help you plan more strategically for the future.

Regardless of the outsource model implemented, the delivery of work is most effective when fully integrated with the onshore team.

What to look for in an outsource partner

Accountants can ensure they implement outsourcing effectively by following some simple rules to deliver the outcomes they need. The most effective outsource partners should demonstrate:

Wide experience of working with UK accounting firms of all sizes
Knowledge of UK VAT legislation and Making Tax Digital requirements
Staff trained in UK tax regulations and accounting standards
Experience with major commercial tax and accounting software.

The onshore team should also check:

References from similar UK firms working with the outsource partner
Arrangements for training and professional development of the offshore team
Turnaround times
Quality control procedures.

Data security arrangements.

There are many ways to share data securely with an offshore accountant – whether through a secure file transfer protocol server, by granting remote access to your server, or sharing files via cloud systems. Regardless of arrangements, the onshore accountant needs to be confident in the offshore IT and physical safeguards, such as anti-virus software, secure VPN connections and 24/7 surveillance.

Unison Globus UK ensures data security by using the most secure, advanced accounting software available with state-of-the-art systems and other physical safeguards to prevent the loss or misuse of data. We are GDPR and ISO 27001 compliant and use cloud-based solutions to ensure data cannot be downloaded, mitigating the risk of data loss or IP theft.

The closer a VAT filing deadline gets, the more expensive small oversights become.

An unreconciled transaction. A missing VAT invoice. A client record that wasn’t reviewed when it should have been. Issues that may seem minor earlier in the quarter can quickly create delays, rework, and compliance risks as the HMRC VAT return deadline July 2026 approaches.

For UK accounting firms, preparing for a VAT filing deadline is about more than submitting returns on time. Firms must review client records, verify VAT treatments, resolve discrepancies, and ensure compliance with Making Tax Digital (MTD) requirements, all while managing multiple deadlines and competing client priorities.

The strongest VAT compliance processes are built long before a return is submitted. Identifying gaps early, standardising review procedures, and maintaining accurate records can help firms reduce risk and avoid unnecessary pressure as deadlines approach. This checklist outlines the key areas accounting firms should review ahead of the July 2026 filing period and strengthen their VAT Return Preparation & Filing Services.

Why VAT Compliance Remains a Priority for Accounting Firms

VAT is one of the UK’s largest sources of tax revenue, generating approximately £179.6 billion in receipts during the 2025/26 tax year. As a result, VAT reporting remains a significant area of compliance focus for HMRC.

At the same time, HMRC’s compliance activity has continued to increase. Recent data showed VAT investigations involving medium and large businesses rose by 31%, while the estimated VAT tax gap widened to £11.9 billion.

For accounting firms, this means that accurate VAT Return Preparation & Filing is about more than meeting a deadline. It requires consistent processes, thorough reviews, and timely resolution of issues before a return reaches the submission stage.

Consider a common scenario. A client submits records shortly before the filing deadline, only for the review team to discover unreconciled transactions and missing VAT invoices. What appeared to be a routine return suddenly requires additional investigation, corrections, and client follow-up, all within a compressed timeframe.

Multiply this across dozens of VAT-registered clients, and the challenge becomes clear. As the HMRC VAT return deadline July 2026 approaches, firms that rely on structured review procedures are often better positioned to manage workloads, reduce errors, and maintain compliance standards across their client portfolio.

Key VAT Filing Requirements Firms Should Review Before Submission

A VAT return should never begin at the submission stage. By the time a return reaches final review, the underlying records, calculations, and supporting documentation should already have been validated.

Before filing returns ahead of the VAT return deadline July 2026, accounting firms should review the following areas:

VAT Records and Supporting Documentation

Businesses are required to maintain records that support the figures reported on their VAT returns. Missing invoices, incomplete expense records, or undocumented adjustments can lead to inaccuracies and create delays during the review process.

Sales and Purchase Reconciliations

Reconciliations help confirm that VAT calculations are based on complete and accurate transaction data. Any differences between accounting records and VAT reports should be investigated before a return is finalised.

VAT Coding and Transaction Treatment

Incorrect VAT coding remains one of the most common causes of reporting errors. Firms should review whether standard-rated, reduced-rated, zero-rated, exempt, and reverse-charge transactions have been treated correctly.

Input VAT Recovery

Input VAT claims should be supported by valid documentation and reviewed for eligibility. Errors in reclaiming VAT can increase compliance risk and result in future corrections.

Making Tax Digital (MTD) compliance support

Under Making Tax Digital requirements, VAT records must be maintained digitally and submitted through compatible software. Firms should confirm that digital records are complete and that submission processes remain compliant.

Internal Review and Approval Procedures

A consistent review process can help identify discrepancies, unusual transactions, and calculation errors before submission. Firms managing high volumes of returns often benefit from standardised review workflows that reduce the risk of oversight.

Once these areas have been reviewed, firms can move to a more detailed compliance checklist to help ensure returns are ready for submission.

Common VAT Errors That Can Delay Submission

Not every VAT issue stems from a complex technical rule. In many cases, filing delays and corrections can be traced back to routine oversights that were missed during preparation or review. Identifying these risks early is an important part of meeting VAT filing requirements and ensuring returns are ready for submission.

Incorrect VAT Treatment

Transactions that are assigned the wrong VAT treatment can affect the accuracy of reported figures and create additional work during the review process. This is particularly common where businesses deal with multiple VAT rates or less frequent transaction types.

Missing Supporting Records

A return is only as reliable as the records behind it. Missing invoices, incomplete expense documentation, and unsupported adjustments can create uncertainty and slow down the review process.

Outstanding Reconciliations

When differences between records remain unresolved, reviewers are often forced to spend valuable time investigating discrepancies close to the filing deadline. Addressing these issues early can help avoid unnecessary delays.

Errors in VAT Recovery

Reclaiming VAT without appropriate documentation or including ineligible expenses can result in inaccuracies that require correction later. Input VAT should always be reviewed alongside supporting evidence.

Late Adjustments

Changes made at the last minute are more likely to be overlooked. Whether the adjustment relates to revenue, expenses, or VAT treatment, it should be reviewed with the same level of scrutiny as the original transaction.

Digital Recordkeeping Issues

Maintaining digital records is now a routine part of VAT compliance. Gaps in recordkeeping, broken digital links, or incomplete data can create problems even when the figures themselves appear accurate.

Many of these issues are preventable when firms follow a consistent review process throughout the filing cycle. Reviewing records against key VAT filing requirements and addressing discrepancies early can help firms improve accuracy, reduce rework, and support a smoother VAT return submission UK process.

Completing a checklist is only part of the process. The real challenge for many accounting firms is ensuring these reviews are carried out consistently across multiple clients, reporting periods, and filing deadlines. This is where structured workflows, and additional compliance support can play an important role in maintaining accuracy and efficiency.

Why Firms Use Outsourced VAT Services During Filing Periods

For many accounting firms, VAT compliance is a recurring responsibility that must be delivered alongside bookkeeping, accounts preparation, payroll, tax, and advisory services. As filing deadlines approach, maintaining review quality and submission timelines can become increasingly challenging, particularly when client volumes grow or workloads fluctuate.

This is one of the reasons firms turn to outsourced VAT return services and broader accounting and bookkeeping outsourcing services to support internal teams during busy compliance periods. Rather than replacing in-house expertise, outsourcing is often used to extend capacity, manage recurring workloads, and help firms maintain consistent service levels.

Many accounting firms also rely on external support when managing multiple deadlines across VAT, bookkeeping, and audit and assurance engagements, especially when internal resources are stretched during compliance-heavy periods.

Support can be provided across a range of activities, including:

VAT return preparation and review
Transaction reconciliations
VAT data validation
Supporting documentation reviews
Making Tax Digital compliance support
Submission readiness checks

By choosing to outsource VAT return services, firms can reduce administrative pressure on internal teams while ensuring VAT-related work continues to move forward during peak filing periods. This can be particularly valuable when managing multiple deadlines, responding to changing client demands, or addressing temporary resource constraints.

As compliance expectations continue to evolve, many firms are looking for ways to strengthen delivery capacity without compromising quality. Access to Expert VAT Services can provide additional flexibility, helping practices maintain accuracy, improve turnaround times, and support clients more effectively throughout the filing cycle.
