4.2 Making Tax Digital (MTD) & Digital Record Keeping

4.2 Making Tax Digital (MTD) & Digital Record Keeping

Making Tax Digital (MTD) for VAT is a statutory regime designed to modernize the UK tax system, reduce avoidable calculation errors, and streamline compliance. Introduced in phases by HMRC, MTD requires all VAT-registered businesses to maintain digital accounting records and submit their 9-box VAT returns electronically using approved software. Understanding the operational and legal scope of MTD is critical for AAT Level 3 candidates.

The MTD Statutory Mandate

MTD for VAT was introduced under the Finance Act 2017 and secondary regulations:

• April 2019 Phase: Mandated for all VAT-registered businesses with taxable turnover exceeding the compulsory VAT registration threshold (£85,000 at the time).
• April 2022 Phase (Universal Rollout): Mandated for ALL VAT-registered businesses in the UK, regardless of turnover, including voluntarily registered businesses.

Under MTD, manual paper returns, direct web-form typing into the HMRC online portal, and paper ledger books are legally prohibited.

Functional Compatible Software & API Submissions

HMRC defines Functional Compatible Software (FCS) as a software program, or a set of software programs, that can perform all of the following functions digitally:

1. Maintain and preserve mandatory digital VAT records for at least 6 years.
2. Prepare 9-box VAT returns from those digital records.
3. Communicate electronically with HMRC via an Application Programming Interface (API) to submit return figures and receive confirmation.

Software Types & Bridging Software

• Commercial Accounting Software: Packages such as Xero, QuickBooks, or Sage natively store records and contain built-in API integration to file 9-box returns directly.
• Bridging Software: For businesses using spreadsheets (e.g. Microsoft Excel) to maintain digital records, bridging software is an API-enabled digital tool that extracts the final 9-box totals directly from the spreadsheet cells and transmits them to HMRC.

The Digital Links Mandate

A central requirement of MTD is the Digital Link. A digital link is an electronic transfer or exchange of data between software programs, products, or applications without human intervention or manual re-keying.

[!CAUTION] Strict Prohibition of Manual Transfers Under MTD regulations, manual copy-and-paste (Ctrl+C / Ctrl+V), typing data from one spreadsheet to another, or manually transcribing figures between accounting software modules is ILLEGAL.

Mandatory Digital Record Keeping Requirements

Businesses must store specific transaction details in a digital format. The digital records must include three core categories:

1. Designatory Data

• Legal business name and trading name.
• Principal place of business address.
• VAT Registration Number (VRN).
• Details of any special VAT schemes used (e.g. Cash Accounting Scheme, Flat Rate Scheme, Annual Accounting, Retail Schemes).

2. Digital Records of Supplies Made (Outputs)

For every supply made, the software must record:

• Time of supply (tax point date).
• Value of supply excluding VAT (net amount).
• Rate of VAT charged (standard 20%, reduced 5%, zero 0%, or exempt) and the resulting VAT amount.

3. Digital Records of Supplies Received (Inputs)

For every supply received, the software must record:

• Time of supply (invoice/tax point date).
• Value of supply excluding VAT (net amount).
• Amount of input VAT to be claimed.

Special Rules for Retailers (Daily Gross Takings)

Retail businesses making thousands of micro-transactions daily are exempt from recording line-by-line sales digitally. Instead, they are permitted to record Daily Gross Takings (DGT) as a single digital summary entry for each trading day.

Statutory Exemptions from MTD

HMRC grants statutory exemption from MTD rules only under narrow, strictly defined circumstances. Exemptions are not automatic; a business must formally apply to HMRC and receive written approval.

1. Religious Beliefs: Business owners whose religious beliefs are incompatible with using computers or electronic communications (e.g., certain strict religious orders like the Plymouth Brethren).
2. Practical Impossibility: Individuals for whom it is not reasonably practicable to use digital tools due to advanced age, disability, or extreme geographical remoteness with no access to broadband or cellular internet.
3. Insolvency: Businesses subject to formal insolvency, liquidation, or administration procedures.

Worked Scenario & Exam Traps

Scenario: Highfield Ltd uses an Excel spreadsheet to record sales and purchases. At the end of each quarter, the bookkeeper copies the total sales figure using Ctrl+C and pastes it into a separate bridging spreadsheet (Ctrl+V) before filing via MTD.

• Analysis: Highfield Ltd is in direct breach of MTD rules. While using spreadsheets and bridging software is permitted, copying and pasting data between spreadsheets breaks the mandatory digital link. To achieve compliance, Highfield Ltd must replace the copy-paste action with a cell formula link (e.g. =SalesSheet!G50) or export/import a CSV file.
