Continuous Transaction Controls CTC; digitisation of VAT invoice reporting

Real-time transaction-based reporting and pre-clearance of VAT invoices to tax authorities to improve tax collections and simplify compliance

Governments seize control of invoicing process

As governments around the world look to close the VAT Gap – missed VAT or GST tax collections – many are turning to mandated live invoice reporting and validation. .This is commonly termed Continuous Transaction Controls (CTC) or transaction-based reporting. It comes in a number of forms, including e-invoices or transaction list reporting. And most countries now impose validation checks and cross-checking to customer records (in real-time) before invoices are issued – meaning the issuer has surrendered CTC is offering opportunities to simplify compliance further along the reporting chain, including removal of VAT return obligations.

The trend started in South America, with pioneers such as Chile and Mexico, and now is spread to Europe and Asia. The EU is evaluating its own version of Digital Reporting Requirements, but faces challenges with a proliferation of standards already.

At VAT Calc, we are passionate about getting the most complex VAT or GST calculation right without expensive or lengthy implementations and heavy support. This means our customers remain agile to report their transactional data in any CTR format around the world.

Common features of Continuous Transaction Controls (CTC)

  • Reporting of invoices to the tax authorities:
    • Secure electronic or e-invoices format (e.g. Italy SdI); or
    • As invoice transaction listing in XML or similar format (e.g. SAF-T or Control Statements)
  • Invoice data is transmitted to the authorities interface or portal:
    • Automatically via API or similar from invoice issuer’s ERP, accounting, invoice, e-commerce platform, point-of-sale or similar system;
    • Manual upload of listings
    • Manual invoice-by-invoice creation in portal; or
    • Via approved invoice agent
  • Typically, in real-time or within a few days of the creation of the invoice
  • Most tax authorities impose basic invoice validation checks, in real time, and will return a approve, errors or reject message to the issuer
  • Increasingly, the country platforms will also transmit the validated invoice to the customer of the invoice issuer, and only at this point will the invoice be considered legally issued from a VAT perspective. Many countries are becoming increasing sophisticated at enabling customer to review, reject or approve the invoices online in full invoice exchange platforms. This can also include cross-checking of sellers and purchasers invoices and book-keeping.
  • The standardisation of these platforms has been variable. The European Commission is pursuing some harmonisation (see below) following on from its work on the core invoice standarisation. But many countries have already launched their own systems which will present challenges for interoperability.
  • Data from such centralised systems are now being used to prepare pre-filled draft VAT returns which taxpayers can then review, adjust and approve. Thus simplifying the VAT compliance process for both the taxpayer and tax authorities.

EU Digital Reporting Requirements

As part of the EU VAT in the Digital Age reforms currently in publica consultation,  there is a channel for a harmonised Digital Reporting Requirements (DRR) which includes a Continuous Transaction Control (CTC) evaluation. This grew from the 2020 EU Tax Action Plan proposals for a fairer and more efficient EU tax regime.

Tax Engine and VAT reporting with CTC

VAT Calc’s tax engine, ‘VAT Calculator’, has been developed with the EU’s VAT in the Digital Age reforms in full focus, including Continuous Transactions Controls agility to live calculate and report invoice data. And since VAT Calculator is built on the same single platform are our VAT Filer product, there is full reconciliation on VAT return reporting.
