Short answer

How do I check EU VAT compliance with AI?

Your AI runs transaction data through the check_vat_compliance tool to identify the correct regulatory path. You'll get a clear breakdown of whether a sale falls under domestic rules, the One Stop Shop (OSS), or reverse charge requirements.

Tax path outcomes.

Where every transaction lands.

The AI categorizes every transaction into one of three regulatory buckets.

DOMESTIC

Local tax application

The AI identifies when a sale stays within a single country. You get the specific domestic VAT rate to apply.

OSS

One Stop Shop path

The AI flags cross-border B2C sales that qualify for OSS. This tells you which EU member state handles the collection.

REVERSE

Reverse charge logic

The AI detects B2B transactions where the buyer assumes the tax liability. You'll know exactly when to skip charging VAT.

HUMAN

Manual review needed

If the transaction data is missing key identifiers like VAT numbers or locations, the AI flags it for your review.

The workflow

What your AI does when a transaction arrives.

The AI processes raw transaction details to map them against EU tax regulations.

  1. Data ingestion

    Your AI reads the buyer's location, the seller's location, and the product type from your provided data.

  2. Path determination

    The AI evaluates the relationship between the parties to select the correct tax regime.

    check_vat_compliance

  3. Compliance flagging

    The AI checks if the transaction meets the specific thresholds for OSS or reverse charge.

    check_vat_compliance

FAQ

How this task behaves

  • 01

    Can the AI file my VAT returns automatically?

    No. The AI only identifies the correct tax path and regulatory category for your transactions.

  • 02

    Does the AI change my actual tax settings in my accounting software?

    No. The AI only provides the compliance analysis; it cannot modify your external software or records.

  • 03

    What happens if the buyer's VAT number is invalid?

    The AI will flag the transaction as needing human review because it cannot confirm the reverse charge path.

  • 04

    Can I use this for non-EU transactions?

    No. This specific tool is designed for EU domestic, OSS, and reverse charge logic.

  • 05

    Does the AI store my customer data?

    No. The AI processes the data you provide in the chat session to perform the check.
