How automatic VAT reclamation can save you time and money

Updated: August 2026

Every year, UK businesses miss out on hundreds of millions of pounds-worth of VAT rebates because they simply aren’t being claimed. For many organisations, it can feel like the administrative burden of going through the reclaim process outweighs the cost benefit of securing the return. 

If you’re still looking at VAT reclaim through a manual lens – chasing receipts, cross-referencing invoices and keying data into HMRC and your own accounting systems every quarter – the good news is that automations are available that can capture, classify and validate your VAT data so that getting back what you’re owed is almost effortless.

The trouble with manual VAT recovery 

Manual VAT recovery is still the standard for plenty of UK businesses. As a result, companies often miss out on VAT that they could legitimately reclaim due to avoidable issues like missing receipts and misclassified expenses. They also lose time to what we call ‘shadow work’ – time-consuming, tedious tasks that could be avoided through process improvements.

If you’re losing time to shadow work, you’re losing money to inefficient processes before you even begin to count the value of unclaimed VAT itself. 

• Teams are chasing receipts long after spending is done

• Invoices and receipts are being re-keyed into spreadsheets and accounting systems, creating additional opportunities for human error

• VAT rules are being applied inconsistently across teams, a particularly common problem in travel, entertainment and cross-border spending

• Finance specialists are losing hours to the reconciliation of disparate data sources before preparing VAT returns

"Manual processes can stretch out the reclamation workflow from weeks to months.” Said Ed Eden, SVP Strategic Finance at Perk. “This means that even where all receipts are present and accounted for, your organisation could be wasting time and money on working hours that could be better spent elsewhere.

“In collaboration with Forrester, we found that employees lose around seven hours per week to this kind of shadow work – roughly one full working day for every week worked. Clearly, this is an issue in need of a solution."

Traditional VAT recovery versus AI-assisted reclaim

A traditional VAT recovery process can feel slow, error-prone and heavily reliant on the accuracy of each team member involved from the point of payment through to submitting a VAT return.

1. Employees pay on personal or corporate cards, then submit their expense claims with receipts attached

2. Invoices arrive via email or post to be manually keyed into the system

3. Finance teams check each receipt for VAT information, entering details into spreadsheets or accounting software and coding expenses manually

4. VAT rules are applied using local knowledge and checklists, which may vary between team members and business locations. For example, in Spain there are four different VAT rates for expense management:

   1. 21% standard VAT rate for all goods and services

   2. 10% intermediary VAT rate

   3. 4% reduced VAT rate

   4. 0% VAT rate

Complexities often led to errors in VAT recovery. Mistakes in calculations, missed opportunities for VAT reclaims, and compliance issues are all common pitfalls in traditional VAT recovery.

In contrast, AI-driven processes revolutionise how tasks are performed, automating large portions of the journey from payment to VAT return.

• Receipts and invoices are captured digitally, for example through mobile photos automatically attached to expense submissions

• Optical character recognition (OCR) extracts key details like supplier names, payment dates, net amounts and VAT amounts

• AI models categorise your spending and map it to the correct VAT codes and rates

• Spending rules and policies are applied automatically – for example, blocking the application of client entertainment VAT

• Data flows directly into your accounting or ERP system, ready for use in VAT returns

Because your data has already been correctly coded and connected with digital receipts or invoices, preparing an AI-driven VAT return becomes a simple review and submission process – rather than a multi-step audit trail.

Features of an AI-assisted solution

Automated data extraction

Instead of a human typing out numbers from a crumpled taxi receipt, AI-assisted solutions like Perk use a blend of advanced vision and language technologies to transfer data in seconds.

Receipt images are automatically cropped and adjusted to remove shadows and creases, before OCR technology converts visual pixels into machine-readable text. While traditional OCR can identify characters, AI-powered OCR recognises text even if it’s smudged, handwritten or in an unusual font. 

Natural language processing (NLP) then allows AI to understand the context of your receipts, for example, knowing that £ means GBP currency and vice versa. With NLP, AI can pull out supplier details and transaction data for processing in an instant. VAT can be detected even when it isn’t clearly separated on your receipts, and when invoices are using non-standard layouts.

Data verification and classification

Once your data has been extracted, artificial intelligence performs background checks to cross-reference that information with VAT rules and thresholds, to categorise and classify expenses, and to check accuracy. Any discrepancies and potential errors are immediately flagged for review.

“Correctly determining the VAT treatment of goods and services is a challenge for multinational businesses.” Says VAT Calc’s Richard Asquith. “AI can assist by rapidly analysing product attributes and matching them to tax categories, reducing reliance on manual interpretation.”

Multilingual and multiregional capabilities

If you’re receiving receipts and invoices related to overseas payments, chances are you’re going to need multilingual capabilities in your accounting process. AI-powered VAT reclaim solutions can easily handle documents in a range of languages, and are designed with multiregion VAT regulations in mind. 

AI fraud detection

Irregularities and anomalies in your data may indicate fraudulent activity, whether this is carried out intentionally or by accident. AI can add a new layer of security and compliance assurance to your expense processes, including VAT reclaim, by automatically detecting and alerting you to potential indicators of fraud.

Improved documentation

Automated VAT systems automatically link every line item to its supporting digital document, approval log and coding history, making it easier to respond quickly if HMRC raises a query.
