Many tax issues arise not from applying the wrong VAT rate, but from miscalculating the taxable base to which that VAT is applied. Pass-through expenses, subsidies, discounts, unpaid amounts, or advances are some of the situations that generate the most errors and, consequently, tax adjustments and penalties.
When it comes to VAT, most companies focus their attention on the applicable tax rate. However, experience shows that many problems with the Tax Agency arise earlier—specifically when determining the tax base.
The tax base is the monetary amount to which the corresponding VAT rate is applied. It seems like a simple matter, but it isn’t always so. The regulations include numerous specific provisions that require certain items to be included and others to be excluded, as well as the need to subsequently adjust the amounts initially reported.
An incorrect interpretation can result in additional tax assessments, penalties, and late-payment interest.
1. Not everything a company collects is excluded from the tax base
As a rule, the tax base consists of the total consideration received from the customer or even from third parties. This means that, in addition to the main price, other incidental amounts related to the transaction must be included.
These include:
- Shipping costs.
- Commissions.
- Insurance premiums.
- Expenses passed on to the customer.
- Containers and packaging.
- Taxes related to the transaction, except for VAT itself.
2. Interest Is Not Always Included in the Tax Base
The general rule states that interest accrued before the time VAT becomes due is included in the tax base. Conversely, interest resulting from deferrals occurring after the supply may be excluded provided certain legal requirements are met.
3. Subsidies may require the collection of additional VAT
Not all subsidies are treated the same. When a government subsidy is directly related to the price of the goods or services provided, it must be included in the tax base. Conversely, subsidies intended to finance infrastructure, investments, or activities of general interest generally do not form part of the tax base.
4. Reimbursements continue to cause numerous errors
Reimbursements are paid by the service provider on behalf of and for the account of their client. They are not part of the tax base, but very strict requirements must be met for this to apply. It is essential that there be an express mandate from the client, the original invoice be issued in the client’s name, the exact same amount paid be passed on, and the service provider does not deduct the input VAT.
5. Subsequent discounts require a VAT adjustment
Discounts granted after the invoice is issued may reduce the tax base. This occurs, for example, with so-called commercial “rebates.”
6. What happens when the customer doesn’t pay?
The VAT Law allows for the recovery of charged but uncollected VAT in certain cases. Among other requirements:
- A minimum period of six months or one year must have elapsed since the VAT became due, depending on the volume of transactions.
- Collection must be pursued through the courts or by a notary.
- The adjustment must be reported electronically to the AEAT.
- A corrected invoice must be issued.
Additionally, there are specific rules that apply when the debtor files for bankruptcy.
7. Transactions Between Related Parties Under Special Scrutiny
When there are related-party relationships, the tax authorities may substitute the agreed-upon price with the normal market value. This occurs especially when one of the parties cannot fully deduct the VAT or when the pro-rata rule applies.
