Common Mistakes That Cost You
Forgetting the Digital Certificate
Without a digital certificate, no online transaction with the government is possible. Up to 6 months delay.
✅ Obtain the FNMT certificate before anything else
Missing Quarterly Deadlines
Modelo 303 and 130 must be filed every quarter before the 20th. Late = fine from €100 upwards.
✅ Save the AEAT tax calendar on your phone
Issuing Incorrect Invoices
An invoice without NIF or IVA is legally invalid and cannot be deducted.
✅ Use approved invoicing software
Choosing the Wrong Legal Structure
Setting up an SL with income below €40K/year adds costs without real benefit.
✅ Consult an accountant before registering
Using a Personal Account for Business
Mixing personal and business money causes audit problems in the event of an inspection.
✅ Open a separate account from the very start
Starting Activity Before Alta
Issuing invoices before official registration with AEAT and RETA is a tax offence.
✅ Register first, then issue your first invoice
