Officials say the deal is essential to meet the growing energy demands of Bangladesh, which is facing a daily gas shortage of up to 14m cubic metres or about 25% of its totalrequirement.
But it is not clear whether the move will help to address the country's worsening energy crisis, since it faces a daily shortfall of around 2, 000 megawatts of electricity - or about one-third of its totalrequirement.
Confusingly, the annual tax return does not supersede an existing monthly requirement to report and pay tax on non-taxed income if total earnings exceed a certain threshold.
