Advice needed

BernaO

one of client did register for Trademarks this year. I put trademarks register under intangible -trademarks and Amortization of trademark can add profit and loss as expenses. I need advice for two points:
1. amortization of trademarks can nor be deductible from taxable income so I should add back amortization such as depreciation when I calculate corporation tax.
2. If I calculate amortization in profit and loss account I can still claim Capital allowance for trademarks, If I can claim capital allowance for trademarks and I shouldn't calculate amortization or should calculate amortization if even i claim capital allowance?

Many thanks for helping
