Investment tax credit must be added to income and deducted from assessed tax for discretionary tax review.

The Administrative Court ruled that the investment tax credit must be included in the calculated income and subsequently deducted from the assessed tax amount when conducting a discretionary tax review. The taxpayer argued for the application of this specific tax relief mechanism under the Investment Allowance Act for the 1983 tax year. The court affirmed that the credit functions as a tax reduction requiring both income inclusion and final deduction to ensure accurate discretionary assessment.
