IRPC: what to expect from corporate income taxation
The Corporate Income Tax Code accompanies the IRPS reform and aims to simplify the current structure of company taxation.
The reform has two parts that work together. IRPS covers individuals; IRPC covers companies and replaces the current framework for taxing corporate profits. It is no accident that Category B of IRPS points, for taxpayers with organised accounts, precisely to the IRPC rules: the two codes were designed to fit one another.
The stated objective is simplification. Fewer scattered statutes, assessment rules closer to international practice and a more direct relationship between accounting and the taxable base. For companies with well-organised accounts, the transition tends to be administrative. For those with weak records, it is the moment that weakness becomes expensive.
Three fronts deserve attention now: the quality of the accounting that will underpin the assessment, documentation of costs whose deductibility may be questioned, and the treatment of transactions with related or non-resident parties.
Until the final law is in force, the best investment is internal organisation. No tax reform penalises a company whose books are in order.
