VAT change

Hello,

While creating document we charge tax code in addition to the amount:

tax base amount 100

tax 16 %

total amount 116

We do tax return to the tax authorities at the collection status. When the customer pay 116 we transfer 16 to the tax authorities,

Now we face a case of VAT change from 16% to 17%. Therefore I sould collect 17 but in my system the document amount is 116 and not 117.

Is there a way to deal with VAT change?

Thanks,

Ben
