OnlinePajak offers Indonesian individuals and enterprises free tax-filing software that allows them to prepare, pay and file their taxes. Having worked closely with the Indonesian Tax Office for three years, OnlinePajak is an official application service provider under ministerial decree. To sustain this free service, Online Pajak generates revenue from selling four value-added services to its user base: tax payment processing, company invoice processing, payroll software, and short-term financing to clients for invoice factoring and tax payments. OnlinePajak estimates that in 2017 tax year $3.3bn of revenue was collected by the government through its platform (3% of the state budget). This makes OnlinePajak one of the leading providers of e-taxation services in Indonesia.
