FIZ is an app for independent professionals in Portugal that automates tax declarations and provides certified invoicing. It's designed for sole traders who need to manage their VAT and Social Security obligations without hiring an accountant. The system is certified by the Portuguese Tax Authority (AT).
It simplifies the entire process, from creating an invoice to submitting your periodic tax forms. FIZ automatically calculates what you owe for VAT and Social Security based on the invoices you issue. When a deadline approaches, you review the declaration and submit it with one click. This avoids errors and missed deadlines.
The platform combines several tools into one place.
What sets FIZ apart is its Tax Shield guarantee. This provides a monetary payment if a declaration submitted through the platform results in a fine. The service is fully integrated with the official tax and social security systems, ensuring your submissions are secure and timely.
