In particularly serious cases, the additional tax administration can impose extra additional tax at the rate of 40 per cent, in addition to the ordinary rate. To identify whether the additional tax will exist if the original tax rate is invalid or illegal. We will investigate the precedent case of supreme court and tribunal judge what they make decisions in the disputes of tax collection between tax authority and claimant for adjudgment.
