SIBLINGS squabble all the time but quarrelling over tax reliefs do not immediately come to mind.

The Inland Revenue Authority of Singapore said last year there 3,000 cases of people who fought over who would claim parent relief on their taxes.

The parent relief is a tax break that recognises single or married taxpayers who look after their parents.

And that is the reason why the taxman now wants to seek consultation from the public on how to manage this process.

Common scenarios highlighted by IRAS include taxpayers who cannot agree who is should be the only person claiming the parent relief, or how they should share the amount claimed if they wanted to do so.

IRAS wants to hear views of how the parent relief should be claimed.

The public can give comments via a poll on feedback unit Reach - which stands for reaching everyone for active citizenry @ home - as well as through email at public_consultation@iras.gov.sg, and snail mail.
