EBTax Issue to split the tax --URGENT

HI Experts,

We have a requirement to increase the existing service tax from 14.00% to 14.5%.

Business wanted the 0.5% from 14.5% to be charged to expense account and 14.00% will be charged to tax liability account which we set on the tax rate.

So it would be like

14.5% = 14.00 (Liabillity account) + 0.5% ( Exepsne account)

I would like to know , how can we split the 14.5% into two tax lines so that when user will apply the tax 14.5% , 14% will be tax account and 0.5% will be expense account to hit.

or

is there any way to apply two taxes on invoices with 14.00 and 0.5% ?

Regards,
