How our online tax advice works

A transparent process with no lock-in: we explain every step, send forecasts before each deadline and provide your documents organised by quarter for audits, banks or grant applications.

Working with an online tax adviser does not mean facing the Spanish tax authorities on your own. It means having a team of tax and accounting advisers who take care of everything while you focus on your business. This is how our process works, step by step:

1
Free registration with the tax and social security authorities

We handle your self-employed registration from start to finish: we select the IAE activity codes that best fit your work, file form 036/037 with the Spanish tax authority, register you under RETA and check whether you qualify for the reduced flat rate or other allowances. You do not need to visit an office.

2
Submit your invoices and expenses online

Each month, you upload your issued and received invoices to our online document submission system. The system records and confirms every submission, offering more assurance than email or a shared folder. We record and classify everything; you do not enter any data or need any software. If you are unsure whether an expense is deductible, we confirm it before recording it. We also send timely reminders for outstanding documents and keep reminding you until you confirm that everything has been submitted.

3
We file your quarterly and annual tax returns

We prepare and file VAT (form 303), personal income tax (form 130) and annual returns and summaries (forms 390 and 190, plus your income tax return).

4
Professional review of every tax return

Our professionals always review the result of each return. We notify you the first time, and whenever the amount differs from the usual figure or we detect a missing invoice.

5
Reminder before payment

Five days before payment is due, we send you a reminder with the exact amount so you do not forget.

6
Documents organised by quarter

Your dashboard gives you access to all filed returns, VAT ledgers, proof of payment and tax compliance certificates. Everything is organised by quarter and ready for audits, bank finance applications or public grant applications.
