Withholding in a foral territory
When you pay a salary, a professional's invoice or the rent on premises, you are obliged to withhold and pay over. So far, the same everywhere. What changes in Álava is who you pay it to and on which form: the Diputación Foral, the provincial council, has its own numbering and its own calendar, and the split between provincial and state administration depends on where the payer's tax address is and, in businesses operating across several territories, on the volume of operations.
An Alavese company with a workplace in Burgos or in La Rioja may have to pay withholding into two administrations. That split is not improvised at the year end: it is decided when the payroll is set up.
Two terms sit behind that sentence. Withholding in Spain means the payer deducts a percentage from what it pays and hands it to the tax authority on account of the recipient's own tax; it is not an extra cost to the payer, but failing to do it is the payer’s problem rather than the recipient's. And domicilio fiscal, the tax address, is the address on record with the administration, which is usually what determines which of the two authorities a business answers to.
What gets dragged along most: the rent on the unit
The classic failure in an industrial city is not withholding on the rent of the premises or the warehouse because the landlord said it was not necessary. The obligation belongs to the tenant, and so does the liability for not having complied with it. It is dragged along for years and surfaces when an inspection arrives, with four unexpired years behind it.
The general mechanics, in common-regime territory, are in Modelos 111 and 115; in Álava the substance is the same and the container is not.
We are a firm working with common-regime Spanish tax and with international tax. The ordinary compliance of an Alavese taxpayer is better done from a provincial firm, and we say so without going round the houses; we coordinate with the one you appoint. What we take on is the layer that crosses borders, the state layer, and the matter that neither administration has resolved yet.
Professionals and posted workers
Two matters come up often. The first is the professional invoicing an Alavese company from outside the territory who does not know whether withholding applies or which administration it goes to. The second is the employee the company sends abroad for a few months or a few years, with the effect that has on their tax residence and, on their return, on their reporting duties.
The second is the one that moves the most money and is the worst documented. Planned before leaving, there is room to act; asked about on the way back, something has nearly always been lost. We cover it in Modelo 247 on leaving Spain.
Both matters share a feature worth naming. They are decided by facts recorded at the time — a payroll set up one way, a departure documented or not — and neither of them can be improved retrospectively by a good argument. That is why we would rather look at a posting before it starts than at a return that has already gone in.

Working with Vitoria-Gasteiz, remotely
With the information return on assets held abroad, which is a state matter, we come in fully: it is in Modelo 720. In writing, and with a map at the start: which obligation you have, before which administration and how often, on a single sheet. For a taxpayer active on both sides, that map is worth more than any loose piece of advice.
After that, coordination with your provincial firm if you already have one. We do not compete with it: we take what it does not cover and pass on what it does. And we do not guarantee outcomes before either administration, because nobody serious can.
Where a matter reaches into another country, the adviser there is one you appoint. We keep no network of foreign firms and we will not opine on rules we do not practise; we coordinate with your adviser and make sure the Spanish part of the answer is consistent with theirs.
A professional from Miranda de Ebro with clients in Vitoria-Gasteiz: his withholdings
The other side of what is seen from Vitoria is the professional who lives in common territory, half an hour away, and works mainly for companies in Álava. His income tax and his VAT are state taxes from start to finish, and that is our ground. What gets complicated is the withholding his clients make.
| Clients of a building surveyor in 2026 | Income | Withholding |
|---|---|---|
| Three companies in Vitoria | 42,000 € | 15 %: 6,300 € |
| Private clients in Miranda and Burgos | 6,000 € | No |
| Total | 48,000 € | 6,300 €, 87.5 % of income with withholding |
With more than 70 % of income withheld, in 2027 he does not file Modelo 130, the quarterly income tax prepayment. His VAT, with a turnover like his, is paid in full to the state tax authority on Modelo 303, even though his clients are in Álava. And the 6,300 € withheld is credited in his 2026 return, provided it appears where it should, which is what the warning below is about. If you want us to handle his quarters, the form is the one for the self-employed.
The reverse case reaches us too: a professional from Vitoria who starts working for clients in Burgos or Logroño. There, income tax and VAT are foral and handled by his Álava adviser — they are met before the provincial tax authority, not the state one; the only thing we tell him is that his clients in common territory, under the rule of the payee's address, should pay his withholdings to the Diputación Foral, the provincial authority, and that his withholding certificate has to say so. It is the same problem seen from the other bank.
The calendar of a professional with clients in Álava
| When | What |
|---|---|
| 1 to 20 April, July and October, and by 30 January | Modelo 303 for the quarter; the 130 only in years when he is not exempt |
| January | Modelo 390 for VAT, and asking each client for the year's withholding certificate |
| March | Comparing those certificates with the tax data held by the state tax authority |
| From April to 30 June | Income tax return for the previous year, with the withholdings proved |
The March step is not in any official calendar and it is the one that prevents the most trouble. The tax data can be checked in the state tax authority's online office and show, payer by payer, what each client has declared withholding from you. The general income tax rule is in Modelo 130.
The Concierto Económico, the agreement that shares taxes between the state and the Basque provinces, assigns withholding on professional activities according to the tax address of the person being paid. If you live in common territory and your Álava client, out of habit, pays your withholdings to the Diputación Foral together with those of its Vitoria professionals, those withholdings do not appear in your state tax data. You subtract them in your return, because they were deducted from you, and the state tax authority does not see them. The usual result is a check that disallows them and asks you for the difference, while the two administrations settle it between themselves. We prevent it by comparing each certificate with the tax data in March and, if they do not match, asking the client to correct it before filing. If the letter has already arrived, the form is replying to the tax authority.
