Calculating VAT when it's not shown.

[BliarOut]

Is there a multiplier I can apply to an amount when the VAT component isn't shown eg. on a parking receipt?

I'm trying to fill in my VAT return/pay my expenses and some of my receipts don't show the VAT amount separately.

Good job I put all the amounts in Excel then

I'm only talking about poxy amounts for office stationery, parking etc... The receipts do show a VAT number, just not a VAT component in some cases.
