Availability
Descodify is pre-launch and invitation-only, so we are not accepting new users right now. That also closes IRS filing to anyone without a login. Existing users can still sign in and read their previous IRS declarations. Descodify opens to new users in January 2027. That is the date Descodify opens, not a tax deadline: the Modelo 3 submission period is set separately by law.
Most solo entrepreneurs in Portugal spend €900–1,400/year on compliance. Completo is €228/year.
Accountant fees, tax consultants, and time spent navigating the AT portal. Completo covers invoicing, VAT, Social Security, and IRS filing - and you understand every step.

Frequently asked questions
Can I really invoice for free?
Yes. Starter includes full invoicing built to AT's requirements, with ATCUD, automatic VAT, and every invoice sent to the tax authority. No limits, no trial period.
What's the difference between Starter and Completo?
Starter covers invoicing and income visibility. Completo adds full expense tracking, guided VAT and Social Security submissions, deadline reminders, and IRS filing (your completed declaration, ready to submit - €49 as a one-off, included with Completo). If you want Descodify to walk you through your obligations, Completo is for you.
Do I need an accountant?
Many solo entrepreneurs on the simplified regime handle their own obligations. Descodify explains every step - no jargon, no surprises. If you already have an accountant, Descodify works alongside them - you get visibility, they get structured data.
How much does IRS filing cost?
Free during early access, and early access is invitation-only for now. Descodify is pre-launch and invitation-only, so we are not accepting new users right now. That also closes IRS filing to anyone without a login. Existing users can still sign in and read their previous IRS declarations. Descodify opens to new users in January 2027. That is the date Descodify opens, not a tax deadline: the Modelo 3 submission period is set separately by law. The published rate is €49 as a one-off, included with Completo. Once open, Descodify generates a Modelo 3 XML you can upload to the Portal das Finanças, or a guided walkthrough that shows you what to enter, field by field (campo by campo). The public IRS reader stays free and needs no sign-up.
Can I switch plans?
Upgrade or downgrade anytime. If you cancel Completo, you keep Starter features and access to your data. No lock-in.
Is there an API?
Yes, and it's included on every plan, including the free Starter. Issue invoices, sync customers and products, and build your own integration from your store or back-office. See the developer docs for the full reference and a quickstart.
Is there a discount for annual billing?
Yes. Completo is €15/month when billed annually (€180/year) instead of €19/month.
