Frequently asked questions
Who has to file form 400?
According to the Agencia Tributaria Canaria (ATC, the Canary Islands Tax Agency): “Personas o entidades con actividad empresarial o profesional en Canarias (sede, domicilio fiscal o establecimiento permanente). Es el alta en el IGIC, aparte del 036/037 de la AEAT.”
What happens if I file form 400 late?
If you file it before the tax authority has asked you to and there is an amount to pay, there is a surcharge of 1% plus another 1% for each full month of delay, and of 15% plus interest after twelve months (art. 27 of the Ley General Tributaria, the General Tax Act). If there is nothing to pay, the general penalty is €200, which drops to €100 if you file without having been asked; for information returns it goes by the item of data (art. 198). The details are in the guide to missed deadlines.
Does Mis Obligaciones file form 400 for me?
No. Mis Obligaciones suggests it in your calendar with the reason, takes you to its official page and reminds you a week before and the day before. The filing is done by you, or your gestoría (tax adviser’s office), on the website of the Agencia Tributaria Canaria (ATC, the Canary Islands Tax Agency).
