Registered person should file VAT 3 i.e. monthly return by the 20th day of the month following the tax period. Where the 20th day falls either on a weekend or a public holiday, the return must be submitted on the last working day prior to the weekend or public holiday.
The return must always be submitted whether there is tax payable or not.
Failure to submit and late submission of returns or submission of payment returns without payment of the tax due is liable to a default fine of KSh 10,000 or 5% of tax due, whichever is higher.
An additional interest of 2% per month or part thereof is also levied on the amount remaining unpaid after the due date.
