Secure user accounts

Only key Taxlab staff have access to our Microsoft Azure server space. We provide several configurations for authentication, including multi-factor authentication from Microsoft. You control which user accounts have access to which tax computations.

Taxlab authentication

Users create an individual Taxlab user account for authenticating each session. Authentication is required for each session. A strong password is required and passwords are encrypted. Login details are not remembered by the browser between sessions. User accounts are locked temporarily if incorrect passwords are repeatedly entered

Once enabled, when logging into Taxlab you will be prompted to confirm your identity via your mobile phone. There is an additional monthly subscription cost for this service.

Active Directory authentication

Data transfers and storage

Data transfers between the user’s machine and our Microsoft Azure server space occur over an encrypted channel with SSL encryption. The Taxlab system and data is hosted on a Microsoft Azure data centre as follows.

Physical security

Storage of production data remains with the Azure datacentre network which adheres to strict security procedures. Should data be moved from Microsoft Azure our policy is to encrypt it.

Redundancy and backups

Our production data storage uses the built in geo-replication of Microsoft Azure. We can do a point in time restore for recovery of recent history. Additionally our databases are backed up nightly in multiple locations. Backups can typically be restored within two hours. Data and backups are stored indefinitely by Taxlab, including after termination of a subscription to meet IRD requirements.
