What a gestor does,and what to hand over.

The short answer
A gestor is a Spanish administrative and tax agent. For a non-resident owner, the gestor files Modelo 210 with the tax office on your behalf, using the numbers you supply.
What does a gestor do?
A gestor deals with the Spanish administration for you. For holiday home owners that mostly means filing Modelo 210 for each owner, once for rental income and once for vacant days, and answering letters from the tax office.
A gestor is not the same as a lawyer or an auditor. They rely on the figures you give them.
What should you hand over?
- Rental income for the year, per home
- Costs for the year, with invoices and receipts
- The number of days let, used by you, and empty
- The cadastral value, from the IBI bill
- Each owner’s NIE, ownership share and certificate of tax residence
The cleaner this package is, the less time the gestor spends and the fewer questions come back.
What does a gestor cost?
Fees differ by firm and region. Most charge a fixed price per return, per owner. Ask for the price per return in writing, and ask whether rental income and vacant days are charged separately.
Do you need one?
You are not required to use a gestor. You can file Modelo 210 online yourself with a Spanish digital certificate. Most non-resident owners use one because the form is in Spanish and mistakes are expensive to correct.
Where does Casatax fit?
Casatax prepares the numbers and the export. Your gestor files. Filing is a separate service from your gestor, and you stay responsible for the return.
Questions
Does the gestor check my figures?
Only as far as you agree. Most file what you provide, so the bookkeeping has to be right before it reaches them.
Can my gestor be anywhere in Spain?
Yes. Filing is online, so the gestor does not need to be near your home.
Who is responsible if the return is wrong?
You are, as the taxpayer.
