1.4 VAT Records, Retention & HMRC Powers of Inspection

1.4 VAT Records, Retention & HMRC Powers of Inspection

VAT is a self-assessed tax. HMRC does not check every invoice before a return is filed; instead the law requires the business to keep a complete audit trail and gives HMRC the power to come and look at it afterwards. That is why the AAT scope of content for this unit asks you to understand what records must be kept, how long they must be kept, how they may be kept, the penalties for failure, and HMRC's rights of inspection. This section covers all five.

1. What Records Must Be Kept

A registered business must keep enough records to show that the figures on each VAT return are right. HMRC does not prescribe a single filing system, but it does prescribe the content. In practice the required records fall into three layers.

Layer 1: The business records

These are the ordinary books and documents the business would keep anyway:

• Copies of all sales invoices issued, including those for zero-rated, reduced-rated and exempt supplies.
• All purchase invoices received for which input tax is claimed, plus receipts for cash purchases.
• Credit and debit notes issued and received.
• Import and export documentation, including monthly postponed import VAT statements and C79 import VAT certificates.
• Till rolls, daily gross takings records and bank statements.
• Records of anything taken out of the business for private use.
• Records of items on which input tax cannot be reclaimed (see section 2.2), so the exclusions can be evidenced.

Layer 2: The VAT account

The VAT account is a specific statutory record — a summary that links the business records to the return. It must show, for each prescribed accounting period, two columns:

The totals of the two columns become Box 1 and Box 4 of the return, and the difference becomes Box 5. If an assessor asks you "where does the VAT return come from?", the correct answer is the VAT account, not the sales ledger.

Layer 3: Scheme-specific records

Some schemes add records of their own — a stock book for margin schemes, a record of the flat rate percentage used and the date it changed, or daily gross takings for a retail scheme. Under Making Tax Digital, the digital records must additionally include designatory data and, for each supply, the tax point, the net value and the rate of VAT.

2. How Long Records Must Be Kept

HMRC can agree a shorter period in specific circumstances, for example where storage would be genuinely impracticable, but this must be agreed in advance and in writing. A business cannot unilaterally decide to shred records early.

3. How Records May Be Kept

Records may be kept on paper, electronically, or as part of a software package, provided they are:

1. Complete — the whole audit trail from source document to return.
2. Readable — HMRC must be able to read them, and a scanned image must be legible.
3. Preserved — an electronic record must remain accessible for the full retention period, which means thinking about superseded file formats and cancelled software subscriptions.

Under MTD the choice narrows: the specified digital records must be held in functional compatible software, and the transfer of data between programs must be by digital link rather than manual re-keying. Section 4.2 covers this in detail.

Practical point: if a business scans purchase invoices and destroys the paper, the scans must capture all the VAT-relevant detail — supplier VAT number, tax point, net, rate and VAT amount. A photograph that crops off the VAT registration number is not an adequate record, and the input tax claim can be denied.

4. HMRC's Rights of Inspection and Visits

HMRC's information and inspection powers sit in Schedule 36 of the Finance Act 2008. In outline, an officer may:

• Issue an information notice requiring the business to produce documents or provide information reasonably required to check its tax position.
• Enter and inspect business premises, business assets and business documents — but not any part of the premises used solely as a dwelling.
• Carry out a VAT compliance visit, usually with at least 7 days' written notice, agreeing a mutually convenient date. Unannounced visits are possible but need approval, and in some cases authorisation from the tribunal.
• Remove and copy documents, giving a receipt for anything taken away.

A visit typically covers the last few returns: the officer walks the audit trail from the return figures back through the VAT account to sample invoices, and tests the high-risk areas — blocked input tax, private use, zero-rating evidence, and scheme eligibility.

What a business should do

1. Confirm the officer's identity and the scope of the visit.
2. Have the VAT account, returns and supporting records available for the periods under review.
3. Answer factually, and say so plainly if a query is beyond your knowledge rather than guessing.
4. Escalate anything that could indicate an under-declaration to your line manager before the officer raises it, so a voluntary disclosure can be considered (section 4.3).

5. Penalties for Record-Keeping Failures

Failure to keep, preserve or produce the required records is a separate offence from getting the return wrong. A record-keeping penalty of up to £3,000 can be charged for each failure. Worse, if records are missing HMRC does not simply give up: it will raise an assessment based on its best judgement of the tax due, and the burden then falls on the business to displace that assessment with evidence it no longer has.

⚠️ EXAM TRAP: Candidates often assume the only consequence of poor records is a fine. The bigger commercial risk is the denial of input tax — no valid VAT invoice means no deduction, regardless of whether the expense was genuinely incurred.

6. Worked Scenario

Scenario: Brackenford Joinery Ltd files quarterly returns. In August 2026 an HMRC officer gives notice of a visit covering the four quarters to 30 June 2026. The bookkeeper finds that:

• The VAT account exists but has not been updated for the fuel scale charges posted directly to Box 1.
• Purchase invoices for the quarter to 30 September 2025 were water-damaged and destroyed; only bank statements survive.
• One supplier invoice for £4,800 including VAT shows no VAT registration number.

Analysis:

1. VAT account gap: not fatal, but it must be reconstructed before the visit so the Box 1 figures can be traced. This is exactly the reconciliation described in section 6.2.
2. Destroyed invoices: the business is inside the 6-year retention period, so there is a record-keeping failure. Bank statements alone do not evidence input tax. The bookkeeper should request duplicate invoices from suppliers immediately — HMRC will accept duplicates.
3. Invoice with no VAT number: this is not a valid VAT invoice, so the £800 of input tax is not recoverable until a corrected invoice is obtained. The claim should be reversed if the corrected invoice does not arrive before the return is verified.
