Does HMRC accept scanned invoices and receipts?

Yes. HMRC accepts scanned copies of most financial records provided they are complete, legible, and capture all information from the original, front and back. A small number of documents, such as certain wet-ink or stamped originals, are worth keeping in physical form.

How long do UK finance teams need to keep records?

Limited companies must keep records supporting their accounts and tax returns for at least six years from the end of the relevant financial year, and VAT records for six years. Some payroll, pension, and asset records carry longer retention periods.

Should we scan our entire finance archive or just recent years?

Most teams get the best value by scanning the most recent two financial years, setting up day-forward scanning for new paperwork, and keeping older records in indexed off-site storage until their retention period expires, at which point they can be securely destroyed.

What resolution and file format are best for scanned financial documents?

Scan at 300dpi minimum and save as searchable PDF, or PDF/A for records with long retention periods. OCR should be applied so documents can be found by supplier name, invoice number, or amount rather than filename alone.

Can we destroy original documents after scanning?

In most cases yes, once scans have passed quality control. Originals should be destroyed through a confidential shredding service that issues a certificate of destruction, and any documents with legal significance in original form should be retained in secure storage instead.

Best Document Scanning Workflow for Finance and Accounts Teams

The best document scanning workflow for a finance or accounts team follows five stages: capture paperwork at a single point of entry, prepare and batch it, scan with OCR to a searchable format, index each document against your ledger references, and only then decide whether originals are stored or destroyed. Finance departments handle the highest volume of business-critical paper in most UK companies — invoices, remittances, expense receipts, bank correspondence — and a workflow that skips any of these stages tends to fail an HMRC enquiry or a month-end reconciliation at the worst possible moment.

Why Finance Paperwork Needs Its Own Workflow

Finance documents are different from general office paperwork in three ways. They arrive continuously rather than in one historical backlog, they carry statutory retention obligations, and they need to be matched to transactions in your accounting system — not just filed.

HMRC requires companies to keep records supporting their tax returns for at least six years from the end of the relevant accounting period, and VAT records for six years as standard. Under Making Tax Digital, digital record-keeping is already mandatory for VAT-registered businesses, so a scanned invoice is not a nice-to-have — it is increasingly the primary record. A generic “scan everything into a shared drive” approach satisfies none of this. A finance-specific workflow does.

The Five-Stage Workflow That Works

1. Single point of capture

Route all incoming financial paper — post, hand-delivered receipts, printed statements — to one owner or one tray. Split capture points are where invoices go missing and duplicate payments start. Many teams pair this with a dedicated email address for PDF invoices so digital and paper arrivals join the same queue.

2. Preparation and batching

Remove staples and paperclips, unfold corners, and group documents into logical batches: purchase invoices, sales invoices, expenses, bank documents. Batch separator sheets let a production scanner process hundreds of documents in one pass while keeping each one distinct. Preparation is tedious, which is exactly why it is the stage most often outsourced to a professional document scanning service that handles prep, scanning, and indexing as one job.

3. Scanning with OCR

Scan at 300dpi minimum and output to searchable PDF (or PDF/A for long-retention records). Optical character recognition turns each invoice into text you can search by supplier name, invoice number, or amount. For accounts payable, look for zonal OCR or invoice data capture, which reads specific fields — supplier, date, net, VAT, gross — rather than just producing a text layer. That field data is what makes the next stage fast.

4. Indexing against your ledger

Every scanned document should carry index fields that mirror how your accounts team actually searches: supplier or customer name, document type, invoice or PO number, date, and financial year. A consistent file naming convention matters too — 2026-07_SupplierName_INV12345.pdf beats scan_0047.pdf in every audit you will ever face. Indexing is the difference between digitised paperwork and a searchable financial archive.

5. Decide the fate of the originals

Once scans are verified, originals either go to secure off-site document storage for their remaining retention period or are securely destroyed with a certificate. HMRC accepts scanned records for most purposes, but some documents — wet-ink contracts, guarantees, certain stamped documents — are worth retaining physically. A scan-and-store or scan-and-shred decision should be made per document class, not per box.

Backfile First or Day-Forward First?

Most finance teams have two problems at once: years of archived paper and a daily inflow of new documents. Tackle them in this order:

Day-forward first. Stop the pile growing. Set up the five-stage workflow for everything arriving from a fixed cut-off date.
Backfile selectively. Scan the last two financial years — the records you are most likely to need for queries, audits, and credit control — and leave older years in indexed off-site storage until their retention expires.
Let retention do the work. Records past their six-year obligation usually justify confidential destruction rather than scanning at all.

This staged approach typically cuts the scanning bill substantially compared with digitising every box on day one, without leaving any compliance gaps.

Compliance Checkpoints for UK Finance Teams

Retention: six years for company and VAT records; longer for some payroll, pension, and capital asset documents.
UK GDPR and the Data Protection Act 2018: invoices and expense claims contain personal data, so access to the digital archive should be role-based and logged. The ICO can fine up to £17.5m or 4% of global turnover for serious breaches.
Audit trail: your workflow should show when a document was scanned, by whom, and that the image is unaltered — quality-control logs from a professional scanning provider cover this.
Secure destruction: originals and time-expired records should be destroyed under a certificate of destruction via a confidential shredding service, not an office wastepaper bin.

Mistakes That Undermine Finance Scanning Projects

The failures we see repeatedly are predictable: scanning without agreed index fields, so nobody can find anything; letting individual staff scan ad hoc on desktop devices, producing inconsistent quality and duplicates; destroying originals before scans have been quality-checked; and treating the project as an IT task rather than a finance process change. Each one is avoidable if the workflow is designed before the first page goes through a scanner — which is why a small pilot batch, checked end-to-end by the accounts team, is the smartest first step.

Get the workflow right and the payoff is immediate: supplier queries answered in seconds, month-end without the filing-cabinet shuffle, and an audit trail HMRC and your auditors can follow without a single box being couriered back to the office.
