What is a bogus self-employed arrangement, and does this contract protect against it?

It exists when the person in fact works as an employee: hours and place set by the company, its orders, its tools and a fixed payment with no risk of their own. The relationship is then one of employment under Spanish law (arts. 1.1 and 8.1 of the Workers' Statute), whatever the contract says. This contract describes an independent relationship; what counts before the labour inspectorate and the courts is how the work is really done.

What if the professional earns 75 % or more of their income from this client?

They are then an economically dependent self-employed worker (TRADE, art. 11 of Spain's Law 20/2007), with a regime of its own: the contract must be in writing with set content and registered with the Spanish public employment service (SEPE). This document does not cover that case: it includes a statement that it does not apply and a duty to say so if it comes to apply.

Must the self-employed professional's invoice carry Spanish income-tax withholding?

If the person carries on a professional activity and invoices a business or another professional, yes: the general withholding is 15 %, and 7 % in the year the activity starts and the two following years. Those taxed by the Foral Treasuries of Navarre or the Basque Country (Álava, Bizkaia, Gipuzkoa) follow their own rules. The contract does not fix the rate: it refers to whatever withholding applies.
