Question 1

What are administrative auctions and which bodies call them?

Accepted Answer

[Administrative auctions](/en/subastas-administrativas) are enforcement and compulsory sale procedures managed directly by public entities to recover unpaid debts (taxes, fines or contributions), without the need for a judge (vía de apremio). The most common bodies that call them are the [Tax Agency](/en/subastas-hacienda-aeat) (Hacienda), [Social Security](/en/subastas-seguridad-social), local councils, provincial deputations and regional governments.

Question 2

What types of seized assets can be acquired in these auctions?

Accepted Answer

The range of assets in administrative auctions is enormous. You can find real estate ([apartments](/en/subastas-publicas-viviendas), detached houses, commercial premises, garage spaces and rural estates) as well as movable assets ([seized vehicles](/en/subastas-embargados-vehiculos), machinery, furniture or transfer rights). All these assets come from the patrimony confiscated from debtors who failed to regularise their tax situation in time.

Question 3

How do I participate in council and provincial deputation auctions?

Accepted Answer

The vast majority of administrative auctions, including those at local level (councils and deputations), are now held electronically on the [BOE Auction Portal](/en/subastas-boe). To bid, log in with your digital certificate or Cl@ve and make a prior deposit or consignación (generally 5% of the auction value). If your bid is not the winner, the body returns the full retention to you.

Question 4

What risks and legal charges do I assume in an administrative award?

Accepted Answer

The biggest risk for an investor in the administrative route is prior registered liens. When you win a property seized by a council or the Tax Authority, you inherit and must take on all preferential debts that existed before that seizure (such as a prior bank mortgage). To avoid buying someone else's debts, subastAI's AI audits the auction notice and property registry entry, showing you the hidden risks before you bid.

Question 5

How do I calculate the real return on a public administration asset?

Accepted Answer

To secure a high return, you need to know the real market value of the asset and subtract your maximum bid, the Transfer Tax (ITP) payment and any prior charges. Instead of complex manual calculations, subastAI's financial engine unifies auctions from all Spanish administrations, cross-references Cadastre data and generates an investment audit with your exact profit margin.
