How do I calculate the taxable base?
The taxable amount is the total amount of the consideration.Consideration is understood to be any effective credit in favour of the person carrying out the taxable transaction, derived from either the main or the ancillary services, received or to be received.
Included in the taxable base:
The commissions, transport costs, packing and packaging (including those that are returnable), insurance, premiums for anticipated services, debts assumed in consideration for the operation, and any other expense that is passed on to the recipient of the operation (except for supplements).
Not included in the taxable base:
The discounts and rebates granted prior to or at the same time as the transaction and which do not constitute remuneration for other transactions.
Where discounts or rebates are granted after the transaction is made, the taxable amount must be modified.Likewise, the taxable base must be modified when returnable packaging is returned.
Interest for the deferment or delay in payment of the price usually charged in the market, which is subsequent to the delivery of goods or provision of services, provided that it is stated separately on the invoice.Interest established by law or court decision as a consequence of the delay in payment of the price, and which is of a compensatory nature, does not form part of the taxable base.Example:interest on late payment regulated in the Public Administration Contracts Law.
The supplementary:sums paid in the name and on behalf of the client, by virtue of express mandate of the client.It shall be evidenced by an invoice issued by the supplier to the customer and not to the intermediary.(Example:driving licence fees paid by driving schools in the name and on behalf of their customers).
Where the consideration is not known at the time of accrual it should be fixed provisionally.Once known, the provisional taxable base must be rectified, if appropriate.
If the transaction is in a foreign currency, the selling exchange rate set by the Bank of Spain and in force at the time of accrual shall be applied.
There are specialities in the case of exchanges, deliveries of several goods for a single price, self-consumption, linkage between the parties, transactions between principal and commission agent (see Article 79 VAT Law ).
