Our verdict on IRIS VAT Filer

IRIS VAT Filer is desktop bridging software for accountants, practices and corporate finance teams submitting UK VAT returns to HMRC under Making Tax Digital. It supports VAT returns only and is available as an integrated Accountancy Suite module or as a standalone product. The workflow is suited to practices that need to collect VAT figures from multiple sources, submit through HMRC APIs and coordinate client information and approvals within the IRIS ecosystem.

The product’s main strength is its coverage of the VAT submission workflow. Users can import VAT values from Microsoft Excel spreadsheets, CSV files, KashFlow and Xero, then submit figures to HMRC through Making Tax Digital APIs. IRIS VAT Filer can retrieve VAT obligations, previous submissions, liabilities and payment data, giving practices access to both filing and HMRC account information. Job Profiles provide progress tracking, while links to the IRIS central client database and IRIS Practice Management support structured client workflows.

The platform fits most naturally where an organisation already works with IRIS systems or needs a Windows desktop tool for assisted VAT filing. IRIS OpenSpace adds a client communication and approval connection, which is relevant for practices that need clients involved before submission. Purchasing is handled through contact with sales or an advisor, and the published offering includes both Accountancy Suite integration and standalone access. Practices seeking a Windows-based VAT workflow with HMRC connectivity and IRIS client processes should shortlist it; teams requiring a non-Windows product or fully automated filing should look elsewhere.
