How does Cofactu know which Spanish tax forms apply to me?

Cofactu analyses your real activity: invoices with withholding, rentals, intra-EU transactions and your tax profile. If your operations change, the profile updates without you having to switch forms on manually.

Are the forms filed directly with the AEAT?

Modelo 303 and 111 generate the standard BOE file to download and upload to the AEAT electronic office. Modelo 130 comes out as a draft to complete on the AEAT site. Modelo 115 is awaiting final validation of its record design. For Modelo 190, 347 and 349 Cofactu calculates and validates the data, but direct TGVI filing is still pending deployment and official testing.

Do the Modelo 303 boxes match the accounting?

Yes. The bases and amounts come from the same VAT register book and the same journal entries. You do not have to cross-check two separate systems or retype amounts.

Does Cofactu warn me when a deadline is near?

Yes. The tax calendar calculates the dates of each form and sends reminders in advance. The T-7 reminder (seven days before) is on by default and you can check the status of each obligation from the panel.

Stop chasing
forms and dates.

Cofactu detects what applies to you, calculates the boxes and warns you before the deadline. You review and file.
