What you get
About this skill
What it does
This skill automates the creation of professional tax prepayment memos (voorafbetalingen) for Belgian accountants. It analyzes a client's estimated tax liability, examines payments already made, and generates a structured memorandum that outlines current deficits and future payment scenarios.
Why use this skill
Manually calculating "vermeerdering" (tax increases) and "bonificaties" (bonuses) across multiple quarters is time-consuming and prone to error. This skill handles the math for both corporations (VenB) and individuals (PB), factoring in fiscal year deviations and specific legal forms. Unlike a generic prompt, it follows a rigorous accounting logic: it builds a transparent "config block" of rates, calculates the cost of inaction, and presents clear scenarios to the client.
Supported tools & Output
Designed for use with fiscal data exports or manual input from accounting software. The output is a client-ready memo in Dutch or English featuring:
- A transparent configuration block with current tax rates and deadlines.
- A detailed table comparing different payment strategies (e.g., "Full catch-up in Q3" vs "Split Q3/Q4").
- Practical payment instructions with structured communications.
- Risk sensitivity analysis (e.g., "What if profit is 20% higher?").
