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.
Use cases
- Extract VAT data from Fortnox or Bokio balance reports automatically
- Generate eSKD XML files for seamless upload to Skatteverket portal
- Calculate reverse charge VAT for EU and non-EU service purchases correctly
- Parse scanned receipts and invoices using OCR to build VAT summaries
- Format and print professional SKV 4700 PDF reports for archiving

Known limitations
Designed specifically for Swedish VAT (SKV 4700) and only Swedish VAT — does not handle other countries' VAT/sales tax. The Skatteverket auto-fill flow requires Claude Cowork (browser automation); pure terminal-only setups can still use the offline PDF↔eSKD converter. BankID signing must be done manually by the user — the skill cannot and will not sign on your behalf. Fortnox/Bokio/Visma readers depend on those services' web UIs; layout changes may occasionally require an update. Not yet adapted for the upcoming K2/K3 reporting changes.
