Panama: Domestic Corporate Taxation
Filing Requirements and Payment of Tax
The tax year is the calendar year, ending 31st December, although a different year can be agreed with the tax authorities. A tax return is due within three months (can be extended to six). The previous year's tax return must be accompanied by a forecast of the current year's tax, which is then payable at a rate of 1% per month.
Any under-payment of tax must be paid along with submission of the previous year's return.
