About This Skill
Simplify Your Swedish Tax Compliance
Navigating the Swedish Tax Agency's (Skatteverket) e-service for annual accounts can be a complex and error-prone process for sole traders (enskild firma). This skill automates the extraction, calculation, and registration of the Förenklat årsbokslut (K1), ensuring your financial reporting is accurate and compliant with Swedish accounting standards.
What It Does
This skill handles the end-to-end workflow of preparing and submitting an annual closing. It provides expert-level assistance with:
- Data Extraction: Parsing balances from your General Ledger (huvudbok) and mapping BAS chart of accounts (1xxx–8xxx) to specific Skatteverket codes (B1–B16, R1–R11, and U1–U4).
- Complex Calculations: Automating periodization fund (periodiseringsfond) allocations, VAT reconciliation (momsfordran/skatteskuld), and equity (eget kapital) balancing.
- E-Service Navigation: Expert guidance through the Skatteverket web portal, including handling non-standard UI behaviors like the missing 'Next' buttons on specific forms (B8) and hidden field sections (R5/R6/R7).
- Pre-Submission Audit: Performing structural checks to ensure assets equal liabilities and equity, and verifying the result (R11) against the ledger.
Why Use This Skill?
Unlike generic AI prompts, this skill is purpose-built for the Swedish tax ecosystem. It understands the nuances of the Kontantmetoden (Cash Method) vs. Fakturametoden (Accrual Method), correctly interprets debit/credit sign conventions in Swedish ledgers, and knows exactly how to handle export sales and VAT reporting periods. It transforms a multi-hour manual task into a guided, high-precision operation, reducing the risk of tax audits and accounting errors.
