The problem it solves
An adviser needs to submit returns in your name. There are two ways of achieving that. The bad way is for you to send them your digital certificate and its password, which means giving a third party the ability to sign anything at all as you, for as long as the file exists. The good way is to make an entry in the tax authority's register of representatives, which records exactly what that person may do, in your name, revocably, with a date.
The second way costs nothing and is what the register was built for. It also produces something the first way never can: a trail showing who submitted what, which matters a great deal if a filing is ever questioned.
Three ways to grant it
- You grant it yourself online. You enter the electronic office with your certificate or with Cl@ve, open the register of representatives, choose the procedures you want to cover, enter our tax number and confirm. The entry is live within minutes and we receive it for acceptance. Time: ten minutes. This is the route we suggest whenever you already have a way of identifying yourself.
- You sign the standard form and we lodge it. The tax authority publishes an official representation form. You sign it, we present it with a copy of your identity document, and the office records the entry. Time: a few days, occasionally a few weeks, depending on the office. This is the route for anyone with no certificate and no Cl@ve.
- A notarial power of attorney. Heavier, but it works from anywhere in the world: signed before a notary in your own country, apostilled if applicable, translated if the office asks. It has the advantage of covering things the tax register does not, such as dealing with a bank or a town hall, so it is worth considering if your Spanish affairs go beyond tax.
Which powers to grant, and which to withhold
The register is granular. You are not handing over a blank cheque, and you should not accept an adviser telling you that the widest possible grant is simpler. What is needed for ordinary compliance work is modest.
| Group of procedures | What it lets us do | Our view |
|---|---|---|
| Filing returns and self-assessments | Submit your quarterly and annual forms | Needed. This is the core of it |
| Consulting your tax data | Read what the authority already holds about you: income reported by third parties, cadastral values, previous filings | Needed, and genuinely useful. Most catch-up work starts here |
| Receiving electronic notifications | Letters reach us rather than sitting unread in your inbox | Usually a good idea for non-residents, because the ten-day clock runs whether or not anybody reads it. Decide it consciously |
| Replying in inspection and penalty procedures | Represent you when there is an argument | Grant it when it is needed, not before. This is legal work and it should be a deliberate step |
What it does not allow
A representation entry is not access to your money. It does not permit anybody to move funds, to change your bank details for refunds without your instruction, or to act outside the procedures listed. It can be revoked by you at any moment, online, with immediate effect and without giving a reason. And it does not transfer your liability: the taxpayer remains you, which is exactly why you should read the draft figures we send before anything is submitted.
What usually goes wrong
- The grant is made for the wrong person. If the property is owned by two people, each owner grants their own representation. A single entry by one spouse does not cover the other, and with a non-resident couple that means two sets of returns and two grants.
- The grant is made by an individual when the taxpayer is a company, or the reverse. A company's grant has to be made by whoever holds the power to bind it, and the office checks.
- The representative never accepts. The entry is not complete until the person named accepts it. If nothing seems to have happened, that is usually why.
- The procedure group chosen does not include what is actually needed. The discovery tends to be made at 19:45 on the last day of the filing period. Grant the filing group and the tax-data group from the start.
- Nobody revokes the old adviser. Changing adviser does not cancel the previous representation. Revoke it explicitly, and check the register afterwards to confirm it has gone.
If you are registered for compulsory electronic notification, a letter is deemed delivered ten calendar days after it is made available, opened or not. Holidays do not pause it. For an owner who lives abroad and checks a Spanish mailbox twice a year, that rule turns a routine request for information into a default. Routing notifications to your representative fixes it — but you should know you have done it, and you should still be told each time one arrives. We forward every one on the day it lands.
How long it takes and what happens next
Granted online, the entry is usable the same day. Granted on paper, allow between one and four weeks. Once it is live, nothing else changes for you: you leave your documents in your folder, we prepare the figures, you see them, we file, and the receipt goes into your folder. That is the whole of it, and it is described in how it works.
If you have not yet decided whether you want your own certificate as well, read getting a digital certificate. Our recommendation is to have both: the representation so the work gets done, and your own certificate so you can always look at your own file without asking anybody's permission.
Pieter, Anneke and a certificate that travelled by email
Pieter and Anneke are Belgian and bought a flat in Benalmádena in equal shares. For years their agent asked for Anneke's digital certificate "because it is the only one that works" and filed every return with it, Pieter's included. When they changed adviser they found three things: the old agent still held a file able to sign in Anneke's name, nothing recorded who had filed what, and Pieter's returns had been submitted with a certificate that was not his. Two properly made grants of representation would have prevented all of it.
Name the firm, not the person
When your representative is a firm, the usual practice is to grant representation to the company rather than to one individual. If the lawyer handling your file is on holiday or leaves, the representation stays intact and anyone authorised in the team can still file on time. Check on the form that the tax number you enter is the company's, which begins with a letter, and not that of one of its members. Read the number twice: a single wrong digit authorises a stranger.
Reviewing the register once a year
The same section of the online portal shows, at any time, which grants you have made and which you have received. Look at it once a year, and whenever you change adviser, sell the property or stop having activity in Spain. A revocation takes effect from the moment it is recorded and does not affect anything already filed under the grant: those returns remain yours and remain valid. When you change representative, the order is always the same: revoke, check it has gone, then grant the new one.
Death, a sale, a transfer to a company
If the taxpayer dies, the representation ends with them, and the heirs have to grant their own — for the deceased's outstanding returns and for the new ones. If the property passes to a company or to another owner, the grant does not travel with the flat: whoever is the taxpayer from that point grants it. A grant of representation is a relationship between people, not an appendix to the property.
Why paper grants stall
The standard paper form arrives without a copy of the identity document, without a date, or with a signature that does not match. That is the usual reason the non-electronic route takes weeks. Our holiday let form takes each owner's details separately, precisely so that Pieter and Anneke's story is not repeated.
