The Best Prop Firms in Spain for 2026, Compared

What the CNMV supervises, and why FundedFast is not on its register

The CNMV (Comision Nacional del Mercado de Valores) authorises and supervises empresas de servicios de inversion: firms that execute client orders, manage portfolios, place financial instruments, or hold client money and securities. Those activities are defined by Ley 6/2023, de los Mercados de Valores y de los Servicios de Inversion, which transposes MiFID II in Spain. Our position is that a prop firm evaluation touches none of them. The challenge runs on a MatchTrader demo account, no money of yours is held or invested, no order of yours reaches a live market, and the profit share is paid out of FundedFast's own capital against simulated performance.

That is our reading of the perimeter, not a determination by the CNMV. The CNMV has published no guidance specific to prop firm evaluations, and the Spanish courts have not tested how the model should be classified.

FundedFast holds no CNMV authorisation and claims none. In practical terms none of the protections attached to authorisation apply to what you buy from us: no MiFID conduct or best execution duties, no FOGAIN investor compensation cover, and no access to the CNMV complaints route open to clients of authorised firms. Memento Enterprises Limited operates from Malta, and being established in the EU is not an investment services passport into Spain, which we neither hold nor claim. Before paying any prop firm, this one included, check the CNMV official registers and public warning lists at cnmv.es, then judge the firm on what you can verify: a payout history you can check, the complete rule set published before purchase, an identifiable operating entity, and terms that do not move after you pay.

This is general information about the regulatory perimeter, not legal advice and not a statement of the CNMV's view. Read the terms and conditions in full before buying a challenge.

Paying tax in Spain on what a prop firm pays you

A FundedFast payout reaches you from abroad, and for a Spanish tax resident it is taxable income in Spain. Which box it belongs in depends on how habitual and organised the activity is, and that classification drives both the rate you pay and the paperwork you file.

Occasional activity: the general IRPF rates

Where the activity is occasional, payouts are integrated into IRPF at the general progressive rates. That rate is the state scale plus your comunidad autonoma's own scale added together, so the combined marginal runs from roughly 18% at the bottom to about 54% at the top depending on where you live: approximately 45% in Madrid, 50% in Cataluna and 54% in the Comunitat Valenciana. Navarre and the three Basque territories operate their own foral income tax entirely. Nothing needs registering for this route; the amounts go into your annual return.

Habitual activity: registering as autonomo

Traders who operate regularly and in an organised way generally register as autonomo and declare rendimientos de actividad economica, which opens up deductions for costs such as equipment or data subscriptions where those costs correlate with the income and are properly documented. Registering is not one step: you file the declaracion censal de alta with the Agencia Tributaria on Modelo 036, under an epigrafe of the IAE that matches the activity, and you register with the Seguridad Social under the RETA, which carries its own monthly contribution. There is no binding Direccion General de Tributos ruling on prop firm payouts specifically, so this classification follows the general test in article 27.1 of Ley 35/2006 rather than a settled administrative criterion.

Stablecoin payouts raise a separate reporting question

If you take payouts in USDT or USDC and leave the balance with a provider outside Spain, you may cross into the informative declarations for foreign held assets: Modelo 721 for virtual currencies held abroad, and Modelo 720 for other foreign assets such as accounts or securities. Both are reporting obligations rather than taxes, triggered by balance thresholds of EUR 50,000, applied per asset category on Modelo 720 and to the year end total on Modelo 721, and both sit alongside your IRPF return rather than inside it.

Records and the Modelo 100

Keep the supporting record for every withdrawal: date, amount, the FundedFast reference, and the EUR countervalue at the date of receipt. The correct classification turns on volume, frequency and the means you employ, and the regional scales are revised annually, so confirm your own position with an asesor fiscal before presenting your Modelo 100.
