How can a restaurant in Spain prove to the tax authorities that the tips it shares out among staff are not undeclared sales?

When a restaurant or bar in Spain collects tips, especially by card, and then shares them out among its staff, the key issue in a tax inspection is not just how they are recorded in the till. What really matters is whether the business can prove that the money actually went to the employees. If it cannot, the AEAT (Spanish Tax Agency) may treat those amounts as company income, subject to Impuesto sobre Sociedades (Spanish corporation tax) and, if their voluntary nature is disputed, also to VAT (IVA).

Is an internal distribution list enough?

A list showing names, amounts and payment dates is a good starting point and helps a great deal. On its own, however, it is weak evidence: it is an internal document, it is not signed by the employees, and the burden of proving where the money went lies with the company.

Two concepts should be kept apart:

• Tronc / sharing method: the rule applied (by hours, points, job category, venue…). The list is the application of that rule, not the rule itself.
• Proof of payment: what shows that each employee actually received their share.

How to strengthen the evidence

• Cross-check the list against bank movements: transfers to employees or, if paid in cash, till or bank withdrawals matching the dates and amounts.
• A signed acknowledgement from each employee of the amounts received during the year, always with the real date of signature. It must never be backdated or show amounts that do not reflect reality.
• A document describing the sharing method actually applied, also with the current date.

With these measures, the risk of the inspectors treating the tips as undeclared sales is significantly reduced. It cannot be 100% guaranteed, as it depends on how the authorities assess the evidence.

What about withholding tax and social security?

If it is shown that the money went to the employees, it constitutes employment income paid by the company. Therefore, the liability for unwithheld IRPF (Spanish income tax) (art. 99 of the IRPF Law) and for social security contributions (art. 147 of the General Social Security Law) exists and does not go away. Proving the distribution prevents the tips being treated as sales, but it does not remove this second liability: they are separate matters.

What can be done is to limit it:

• Voluntarily regularise before any formal request. With the tax authorities, the late-filing surcharges under art. 27 of the Ley General Tributaria (General Tax Law) would apply instead of penalties. With Social Security, supplementary contribution returns would be filed with their surcharges.
• Calculate the base accurately, per employee and per company, to know the real amount before deciding how to regularise.

As regularisation affects payroll and contributions, it is advisable to coordinate the tax review with the employment law side.
