Administrative Law

Spanish Tax Agency and tax inspections, fines and penalties, planning, licences and holiday rentals, public liability, appeals and judicial review. In English, Spanish and Russian.

Dealing with the authorities

When the Tax Agency, the Town Hall or another authority gets it wrong

A letter from the Tax Agency, a fine, a refused licence or works being stopped can arrive at any moment. Deadlines to respond are short — sometimes only ten days — and whatever is not raised in time is very hard to fix later.

At Rosmedian Law we review the file, explain your real options and file submissions and appeals on your behalf, including online. If the administrative route is not enough, we defend you before the administrative courts.

  • You have received a request or an assessment from the Tax Agency
  • You have been fined or penalised and believe it is unfair
  • You need a building, business or holiday rental licence
  • You have suffered damage caused by a public service
  • You want to appeal a decision or the authority is not responding

How we work

Short deadlines, fast response

In administrative law time matters: the sooner we review your case, the more options you have.

  1. File review

    We read the notice and the full file, check the deadlines and spot procedural and substantive errors.

  2. Strategy

    We tell you whether to pay, negotiate, make submissions or appeal, with a clear estimate of costs and chances.

  3. Submissions and appeals

    We prepare and file the documents and, where appropriate, ask for payment or enforcement to be suspended in the meantime.

  4. Courts

    If the authority maintains its position, we go to the administrative courts and represent you throughout.

FAQ

What clients ask us most about the authorities

I have received a fine. Should I pay or appeal?

It depends on whether there are solid grounds to appeal. For traffic fines, paying within 20 calendar days of notification cuts the amount by 50%, but you give up the right to contest it. In other penalty proceedings, voluntary payment and admitting liability can each give a 20% reduction. Before paying, it is worth checking the notice, the evidence and the legal classification for defects.

What are the deadlines to appeal?

Against an express decision, an administrative appeal (alzada or reposición) must be filed within one month, and a judicial review claim within two months. In tax matters, the reposición appeal and the claim before the Tax Tribunal also have a one-month deadline. If the authority does not reply (administrative silence), in most cases those deadlines do not run against you.

The Tax Agency has sent me a request. What should I do?

Do not ignore it: the deadline to respond is usually ten working days and failing to reply can lead to a penalty. We analyse exactly what the Agency is asking for, which documents to provide and how to submit them. As a rule, the Tax Agency can only review the last four years.

Do I have to pay while I appeal?

Administrative penalties cannot be enforced until they are final in the administrative route, and tax penalties under appeal are suspended without any guarantee. For tax debts and other assessments, however, you must request suspension and usually provide a guarantee; otherwise they can be collected with surcharges.

I fell in the street because of a broken paving stone. Can I claim?

Yes, through a public liability claim against the Town Hall or the body responsible. You need to prove the damage and its link to the poor state of the public service: photos, witnesses, medical reports. The deadline is one year from the accident or from when the injuries stabilise.

I have works without a licence. Can I be forced to demolish them?

In the Valencian Community, the Town Hall has fifteen years from completion of the works to order planning legality to be restored; on protected rural land there is no time limit. Many works can be legalised if they comply with the planning rules. Before buying a home, it is worth checking its planning status.

What do I need to let my home as a holiday rental?

In the Valencian Community the home must be entered in the Tourism Register, with a municipal planning compatibility report, and since 1 July 2025 you also need the national single registration number, which is mandatory to advertise on platforms. In residential buildings, the owners’ association must approve it by a three-fifths majority. Many municipalities have restricted new licences, so check before you buy.

What are the risks of taking the authorities to court?

In judicial review, as a rule, the losing party pays the other side’s costs, although courts usually cap them at a moderate amount. That is why we assess your real chances with you before filing. In many cases a well-prepared administrative appeal solves the problem without going to court.
