You had paid for the provisional tax for the year of assessment 2007/08(07/08年暫繳稅 xxxx). No more action required by you. The amount has been deducted from the gross refund of tax 應退還稅款 xxxx.
However, if the income in 2007/08 is greater than the income you earned in 2006/07, you still have to pay for the difference of the final tax payable less the amount you had paid for the provisional tax 07/08年暫繳稅 xxxx in next year. And, again, a provisional tax for 08/09.
