For some, the one-month deadline is insufficient to finish their profit tax return form. But luckily, a company can request for an extension. The IRD will send out a Circular Letter at the start of the year to inform representatives about the Block Extension Scheme. It includes programs for block extension and notifications of detailed updates. A further extension of time beyond the Block Extension Scheme extended due dates will be given only in the most extraordinary situations. Any such request should be given in writing, together with an explanation of why the procedure cannot be completed in a timely manner and supporting documentation.
