Question 6 - Is there any immunity to a person chargeable with tax in cases of fraud/suppression of facts/ willful misstatement, who pays the amount of demand along-with interest before issue of notice?

Immunity for voluntary tax payment prevents issuance of notice where tax, interest and prescribed penalty are paid before notice

A person who, before issue of any notice, pays the ascertained tax along with interest and a penalty equal to fifteen percent of the tax involved-whether self-ascertained or ascertained by the proper officer-shall obtain immunity from notice in respect of the tax so paid and no notice shall be issued for that tax.
