The Ministry of Finance (MOF) has automated the tax compliance verification process by creating an online Bidder Portal where bidders, prior to bidding on a contract, can confirm their compliance status in real time.
First time users must register for E-Services. Once registered, bidders may access the new Bidder Portal by logging in using their ONe-key account and selecting E-Services from My Services. ONe-key is available through the ONe–key website.
