The options discussed on this page are found by selecting Menu --> Setup --> Till --> General --> VAT

The VAT table sets the codes that are used in all the calculations, reports, and receipts for items sold via the till. The entries you make in this table will depend entirely on what you have agreed with your local tax office / accountant, be sure to have all the information to hand before making any changes to this screen.

Code 
Reflects what has been set up in the Sales Groups, along with the default Percentage of 20.00%. Whilst slightly mis-leading at face value, this 20.00% should be left in.

Fixed Fee 
The two columns that come under this heading allow any fixed professional fees to be entered (rare, but seen occasionally around Contact Lenses), and the Dispensing Fee Group can link to a matrix sometimes used for working out VAT based on the selling price of frames and lenses. See Dispensing Fees

% Fee 
The most common exemptions are based on Percentages. can also be set, split between Professional Fees (Prof Percent) and Dispensing Fees (Disp Percent). Generally, X (Chairtime) should be 100% exempt for professional fees, and your percentage exemption for dispensing fees are show in the far column. Sundries will always be 0% in both columns.

IMPORTANT NOTE

The new values will only be used for transactions / reporting from that point forward. To run a fix to update previous sales / payments with the new VAT values, please raise a ticket at the top of this page.
