Question 1

What core compliance problems does the eu-vat-oss-calculator solve?

Accepted Answer

This skill automates the extraction and calculation of VAT for quarterly OSS filings by processing raw sales data from various platforms and identifying which sales require tax remittance versus those handled by a 'Merchant of Record'. It solves the complexity of tracking the €10,000 threshold and managing 27 different tax rates.

Question 2

What exactly is included in the purchase?

Accepted Answer

Upon purchase, you receive the full AI agent skill configuration and a specialized Excel workbook template pre-loaded with current EU-27 tax rates and auditable formulas. It includes logic for mapping ISO country codes and platform-specific exports like Stripe and Shopify.

Question 3

How do I set up this skill and which AI agents are supported?

Accepted Answer

This skill is designed for use with leading AI agents and LLMs capable of file processing and data manipulation. Simply upload your sales exports to the agent running this skill, and it will populate the provided spreadsheet automatically.

Question 4

How does the skill handle sales from platforms that already collect VAT on my behalf?

Accepted Answer

Yes, the logic is pre-configured to distinguish between 'Deemed Suppliers' (like Gumroad or Etsy) who collect VAT for you and 'Payment Facilitators' (like Stripe) where you remain liable. This prevents double-taxation and ensures your OSS return is accurate.

Question 5

How are tax rate changes and regulatory updates handled?

Accepted Answer

The skill is updated whenever the EU Commission adjusts VAT rates or the OSS threshold rules, including upcoming changes for 2026. Buyers have access to these logic updates to ensure their bookkeeping remains compliant with the latest regulations.

Question 6

Can I audit the calculations made by the AI?

Accepted Answer

The skill generates a formula-driven XLSX file rather than a static PDF. This allows you or your accountant to verify every calculation and see exactly how the VAT was extracted from your gross sales for auditing purposes.
