Vpf contribution to avoid tax as per new income tax law beyond 2.5 lakh

Max VPF a private salaried class employee can claim to avoid tax as per new income tax law. Like last year Income Tax department created a new law according to which if contribution to PF is more than 2.5 Lakh then the amount beyond this 2.5L will be taxable. Something like that.
So please confirm me how much one can contribute beyond PF amount so that access VPF will not fall in taxable category.


Thanks
