Enterprise systems
Tax administration systems (ITAS / MTS)
An integrated tax administration system keeps a single taxpayer register and runs every tax type on one platform, from registration and filing to collection, objections and appeals.
Why it matters
One platform for every tax type
The problem
Separate systems for each tax type produce conflicting taxpayer records and slow reconciliation. Compliance is hard to see across tax types, and a change in legislation can take months to put into effect.
What changes
A single view of every taxpayer. Legislative changes handled through configuration, not new code. Audit effort directed by risk, and online self-service that lowers the cost of compliance for taxpayers.
What we deliver
The full compliance lifecycle
01
Unified taxpayer register
One record for each taxpayer across all tax types.
02

03
Compliance and enforcement
