UK MTD - MacroExcel

HMRC's 'Making Tax Digital for VAT' aims to avoid 'manual entry' mistakes, and that all underlying VAT line items of the VAT return are not only digitalized but at the end readily available so HMRC can perform soon closer to real-time tax audits. In 2020 the underlying digital VAT accounting data will be submitted to HMRC. That data will be used to review whether the numbers of the nine VAT returns submitted are correct. Not only a digital audit trail should exist when manual changes are made, but VAT controls should be run.

Lets show you how our MacroExcel works

From the main worksheet, it shows it is a natural follow-up exercise. It is user-friendly, and the VAT return preparation is just done in five steps. The VAT controls highlight possible errors either in calculation or in data quality. Tracking manual changes is easy. The upload of the file for UK MTD is done with just one click.

  1. In step 1 you select the taxpayer and reporting period from the ‘drop-down’ menu.
  2. In step 2 you upload the source VAT data with one-click. You select just the source file ‘Standard SAP VAT report’ generated from SAP. The file is uploaded in a separate sheet called ‘SAP_VAT_report’ and includes both line items and summary. The sheet is password protected against any manual entry.
  3. In step 3 you upload similarly the source VAT accounting data. The file is uploaded in a separate sheet called ‘Standard SAP VAT report’ generated from SAP and included both line items, and the summary. Also, this sheet is password protected against any manual entry.
  4. In step 4 you generate the final file in the JSON format in one click. That file can be uploaded to our web-portal and submitted to HMRC.
  5. In step 5 you finalize your work and you save the file with password protection


An overview of the relevant VAT management features of our MacroExcel

The sheet is password protected against manual entries. The mapping in the MacroExcel provides a linkage between the tax code and the VAT return box. The MacroExcel captures corrections in separate columns. The sheet displays the VAT result from the ‘initial’ and the ‘final’ data. In the sheet, a reverse VAT calculation check is performed to identify any errors coming from source data. For example typing mistakes, wrong amounts on invoices, etc.

Multiple ‘cross’ controls are run within the MacroExcel to validate the final result. A linkage exists between the final VAT return data and in a separate sheet called the ‘VAT declaration the UK’.

An extra feature that could be set up as a tailored exercise is that all corrections are done in separate sheet ‘Corrections_final’ – and never on source data. Easy to proceed – enter data you need to correct, mark the correction type, i.e. ‘Include’ or ‘Exclude’. The sheet automatically transfers the result to ‘VAT_calculation’. Tracking changes in the VAT result will be easy.

An extra feature that could be set up as a tailored exercise is that the VAT return results are reconciled against the VAT General Ledger balance in a separate sheet called ‘Reconciliation’. All amounts are automatically filled in from source sheets, i.e. ‘VAT_GL balance’, ‘VAT_calculation’, etc. The sheet highlights differences. It can indicate that some errors exist in reporting. For example, VAT data is posted directly to the VAT account without the use of a tax code and was therefore not captured in the VAT report. Optional functionality can be added that requests the user to explain these differences.

An extra feature that could be set up is the VAT overview that provides an overview of the submitted VAT figures from previous periods. Amounts are automatically filled in. Any significant difference in reported values across periods can indicate that some errors exist in reporting. For example, the sudden drop-down on the sales VAT without any business reason might mean issues with the billing module, etc.). The sheet is password protected against any manual entry.

During the design, we anticipated on the next submission requirement. Besides the nine numbers of the VAT return to perform data analysis, HMRC will request soon to receive VAT accounting data. The MacroExcel we developed can simulate such a tax audit. Our Bridging software developed will be able to upload and display the VAT accounting data, and when internally approved, submit this data to HMRC.

The VAT return MacroExcel is available for ‘All European’ countries. We standardized and optimized the entire European VAT return workflow. All the UK features explained are also included in the country VAT return MacroExcel.

Excel has limitations with handling large datasets. Excel limits the number of rows in a spreadsheet to about one million. The current VAT return process and future requirements combined can result that Excel cannot be used as big data has to be stored. MS Access and ACL software are alternatives we use that both can handle more data.

Short video

Multinationals can have specific manual changes or methods to calculate the numbers of the VAT return periodically. The existing VAT return process has to be optimized to meet the new HMRC objectives. With the MacroExcel, we keep close to the existing operational VAT return process.

Companies with VAT return obligations in the UK often use spreadsheets nowadays during the VAT return process, and those spreadsheets have to be upgraded to meet the new HMRC requirements (see below image). However that is not the only reason to use our MacroExcel.

The advantages of our MacroExcel

Our MacroExcel meets the new tax requirements, and automated data transfer takes place. A digital audit trail exists when manual changes are made and also the MacroExcel protects against 'copy & paste', 'cut & paste', and 'overwrites'. That is vital functionality to be compliant with the UK 'Making Tax Digital' objective. The MacroExcel is archived in SAP and readily available on HMRC request.

The advantages go however a bit further than that as for the tax function it facilitates tax risk management. A company often extracts raw VAT data from SAP to calculate the numbers of nine boxes of the UK VAT return via downloading the data in Excel and subsequently the VAT process owner consolidates the numbers.

In the MacroExcel all relevant VAT data is centrally available and accessible. For solid 'Tax Risk Management' purposes VAT controls are set up by which unforeseen tax risks can be avoided, especially when VAT controls are run during the soft landing period. When gaps are found remediation can still take place before mandatory submissions. That is the time when HMRC will perform similar data analysis to combat VAT fraud, VAT leakages and other non-tax compliance.

Examples of VAT controls that are standard in the MacroExcel are:

  • Reconciliation (boxes of the VAT return and VIES, Intrastat Arrivals & dispatches)
  • Reverse VAT calculation checks performed
  • VAT amounts compared with the displayed net amount
  • ‘Non-standard’ VAT rate checks due to discount processing


The MacroExcel is flexible, and we can add tailored VAT controls such as mathematical and logic VAT health checks at extra costs. When such VAT controls and a simulation of a tax audit is not preferred, we will provide an Excel sheet at small consideration to be used for upload puposes to our Bridging Software.

We upgrade a VAT return process that takes place outside of SAP to ensure it meets the new requirements and objectives of HMRC: archives VAT accounting records and uses our bridging software to communicate VAT return content to the new HMRC portal in an automated way. The VAT controls set up analyse VAT data on non-tax compliance.

When however an SAP add-on is considered the optimal solution to get all functionality in the SAP environment itself, the MacroExcel will only be used during a transitional period from April 2019 till ultimately December 2019. We will use the operational MacroExcel to set up in the SAP add-on the client specific and relevant VAT mapping.
