Tax Depreciation Review Through Data Analysis

A tool for comprehensive tax depreciation inspection and review of tax carrying amount.

The tax depreciation analysis tool enables a bulk review of the register of tangible and intangible fixed assets in accordance with the current tax legislation.

The tax depreciation analysis tool is one of the tools employed in data analytics for the corporate income tax using information from the client’s assets register in the form of a data file. Once the data is uploaded to the analytics tool, automated tests verify the appropriateness of specific provisions of the Income Taxes Act for tax depreciation applied and identify specific items that may be in breach of the Act or could be modified to achieve savings.
