For certified accountants
Every client's Anexo F. The right rate on every lease.
In 2026 four regimes compete on every rent and the most favourable always applies. It's new, complex and easy to get wrong. An engine that gets it right, per lease, across the whole book.
Who is overpaying
Every client in one view, ranked by what they're overpaying. The email you'll send.
Bulk Anexo F
One year, every client, ready to transcribe. Print and CSV.
Deadline board
IMI, AIMI, rent updates, IMT refunds, mortgage resets. For every client, by date.
Your brand
Practice name, initials and colour at the top of every report.
How it works
- 1
The client exports, or you create them here
A file from the landlord area (Settings, Export), or the properties and leases typed in by you.
- 2
You import it
One click. The client appears with Anexo F, audit and deadlines.
- 3
You send the number
“You're overpaying €2,340 a year.” With your name at the top.
From €99/month
Up to 5 clients. Unlimited clients and up to 10 people on the team, €149/month.
See it working
The practice's book, client by client.
One book per client, with their properties, leases and deadlines. Before filing season starts, you see at once who is overpaying and what is missing.
One book per client, kept apart
Their properties, leases and transactions, without mixing or losing any of it.
The whole portfolio at once
Shows who is overpaying income tax, how much there is to recover, and which deadlines close in the next 30 days. As a list, not a search.
Anexo F filings come out in a batch
One per client per year, with the origin of every line, ready for the return.
The team signs in with their own access
Each person on their own account, in the same client book.
Every change is recorded with the name of whoever made it.
The real interface, in miniature. Every figure is an example. None of it is anybody's data.

“Is it worth it?” — the question that arrives by WhatsApp
A client sends you the listing. One click opens the transfer tax for both residences, the real acquisition cost, and the cashflow at the correct Category F rate. For the definitive answer the panel hands the facts to the full analysis, where you set the client's own profile.
