The changes relate both to individual (personal) and corporate income tax returns, and apply to tax returns for 2012 and later tax years.
Provisional assessment request
Under the new rules, a provisional assessment must be timely requested (e.g., before the first day of the fifth month after the end of the tax period, or by 1 May), and the tax return must be timely filed (e.g., before the first day of the fourth month after the end of the tax period, or 1 April).
Still, interest can be charged even if the 2012 individual or corporate income tax return was timely filed before 1 April 2013.
However, under the new rules, interest on an amount of tax due cannot be assessed if, after a taxpayer’s request for a provisional assessment filed before 1 May (or a tax return filed before 1 April), a provisional assessment is imposed that is the same as the amount stated in the request or reported in the tax return.
If, however, after receiving the tax return, the tax inspector chooses to impose a final assessment and refrains from imposing a provisional assessment, interest on tax due will be charged (although the amount of interest will be limited). In this situation, interest will be calculated over the period 1 July through 13 August 2013.
Under the new rules, the interest on tax due is limited to 19 weeks after the tax return is filed, provided that the tax assessment is imposed for the same amount as reported in the tax return. Furthermore, no interest on tax due will be assessed over the first six months after the end of the tax period.
