Taxable base
For those operations to which this special regime is applicable, the taxable base will be determined on a transaction-by-transaction basis, and will be the gross margin that the travel agency has in each one of them.
However, given the difficulty of knowing the actual amount of goods and services purchased at the time of calculating the gross margin by travel agencies (due to rappels in prices, under-occupancy rates or customer advances), the Directorate General of Taxes accepts the following criterion for determining the taxable base (consultation DGT V0100-15):
Provisional determination according to the percentage of the gross margin acquired during the previous calendar year, corresponding with all transactions attached to the special regime:
The taxable amount shall be the result of applying this percentage to the sum of the amount, including VAT , of all travel services accrued during the relevant settlement period.
Adjustment of the taxable base in the last self-assessment of the year according to the difference between the taxable base of the year, calculated by applying the actual gross margin percentage on the amount of travel services accrued during the year (including VAT), and the sum of the taxable bases stated in the self-assessments of the previous periods.
Gross margin means gross margin:
The difference between the amount charged to the customer, without VAT, and the actual amount, including VAT, of the supplies of goods and services made by other entrepreneurs and professionals and purchased by the agency for the realisation of the trip and which are of direct benefit to the traveller.
Services such as the purchase and sale or exchange of foreign currency or telephone, telex, correspondence and other similar expenses incurred by the agency are not considered to have been rendered for the purpose of the trip.
Operation by operation
Taxable amount = Charged to the customer (excluding VAT) - purchases for the benefit of the traveller (including VAT).
