Implementation Capabilities for Vertex Solutions

Rapid legislative changes, such as those stemming from the South Dakota v. Wayfair ruling in the US, and the Making Tax Digital for VAT notice in the UK, require businesses to act now. MKS Tax implements Vertex Cloud, Vertex Indirect Tax O Series for sales tax, use tax, lease tax, and VAT, and Vertex Indirect Tax Returns to help businesses face these challenges confidently.

How the Implementation Works

For businesses using our previous generation tax engines, MKS Tax provides a direct 2-week upgrade path to Vertex Cloud Indirect Tax and Vertex Indirect Tax O Series. No programmatic changes to your ERP systems are needed.

For VAT, MKS Tax supports the full spectrum of VAT compliance concepts, including reporting, partial input VAT recoverability, cash-based VAT accounting, currency conversion, consolidated invoicing, VAT withholding, and electronic invoice records submission.
