Cadrumo¶
Cadrumo is a helper for preparing your Spanish tax forms. It ships as the
aeat command-line application.
This is the landing page for Cadrumo’s documentation. It shows how to turn local records into checked modelo figures and export files. You upload those files yourself to the Agencia Estatal de Administración Tributaria (AEAT). The project source is on GitHub.
Cadrumo is for autónomos, small businesses, and the people who help them prepare Spanish filing records. You prepare one taxpayer’s records at a time. The project is in beta, so expect changes between versions.
The guides on this page are ordered by the usual filing path. Start at the first thing you have not done yet. The path runs from installing the CLI and setting up the taxpayer, through preparing records and deciding what is due, to producing an export and following the full filing loop.
Important
aeat is not tax advice, is not affiliated with AEAT, and does not replace
AEAT’s official tools or professional advice. It builds, checks, and exports
files locally. You file through official AEAT channels yourself and remain
responsible for every declaration you submit. Read the full disclaimer
before you rely on aeat.
Where to start¶
Use this when you are new to aeat and want the shortest path through profile,
transactions, calculation, verification, and local export.
Use this when aeat does not yet know which taxpayer, activity, or local
profile to use.
Use this when records are not yet in the ledger, or when they still need review, classification, export, split, merge, or evidence links.
Use this when imported rows need business, personal, mixed-use, category, or tax-field decisions.
Use this when you need to see which modelos are due and which period to prepare.
Use this when you want the full repeatable loop: prepare, verify, export, file through AEAT, and keep local history.
