    About this skill

    Automated Swedish VAT Reporting (Momsdeklaration SKV 4700)

    Streamline the complex process of filing VAT returns with the Swedish Tax Agency (Skatteverket). This skill automates the entire workflow from data extraction to digital submission, ensuring compliance with the latest 2026 regulations and field mappings (SKV 4700).

    What it does

    • Data Extraction: Integrates with cloud accounting software like Fortnox and Bokio, or parses local bookkeeping folders (PDFs, images via OCR, and text files).
    • Smart Calculation: Automatically maps Swedish accounting codes (e.g., 2611, 2640, 3001, 3308) to the correct VAT boxes (Ruta 05-49).
    • Validation: Performs critical checks, such as verifying reverse charge consistency and ensuring export sales are excluded from Box 05.
    • eSKD Generation: Creates valid XML/eSKD files (ISO-8859-1) for direct upload.
    • Automated Filing: Navigates Skatteverket's e-service via Chrome to fill in forms or upload files via the DataTransfer API.

    Why use this skill

    Manual VAT reporting is prone to errors, especially regarding reverse charge (omvänd skattskyldighet) and European vs. non-European service purchases. This skill eliminates "copy-paste" risks and handles the technical nuances of Skatteverket's portal, including Shadow DOM navigation and specific rounding rules used by professional software like Fortnox.

    Output

    The skill produces a detailed calculation summary for review, a professional PDF breakdown of all boxes, a valid .skd file for submission, and finally, a confirmation receipt from Skatteverket after your approval.

    Browser access is used to log into Skatteverket's e-service via BankID and to fill the SKV 4700 form on the user's behalf, plus to read VAT reports from web-based bookkeeping tools (Fortnox, Bokio, Visma). Read/Write Files stores the generated eSKD XML and PDF reports locally. Terminal runs the offline Python helper for PDF↔eSKD conversion. Network access is only used for the bookkeeping providers and Skatteverket itself — no telemetry, no third parties. The user signs every submission manually with BankID; the skill never has access to credentials or signing keys.
