Automating Multi-Rate Tax Extraction with Eagle Doc's Invoice OCR API

In today's complex business environment, invoice processing remains a significant challenge for finance teams worldwide. With Eagle Doc's Invoice OCR API, businesses can now extract granular tax information at the line item level—a crucial capability for accurate accounting and tax compliance.

The Challenge of Multiple Tax Rates

Many countries implement varied tax rates across different product categories and services. This complexity appears directly on invoices as multiple tax percentages applied to different line items. Traditional OCR solutions often struggle with this nuance, extracting only the total tax amount while missing the critical per-item tax rates.

Eagle Doc's OCR API addresses this challenge by identifying and extracting tax percentages for each line item, even when multiple rates appear on a single invoice.

How Eagle Doc's Tax Extraction Works

The API employs advanced machine learning algorithms to:

1. Identify individual line items on an invoice

2. Extract the tax percentage associated with each item

3. Cross-reference tax labels with the tax summary section

4. Match tax codes or labels to their corresponding rates

5. Provide structured data output with per-item tax information

When an invoice contains tax labels (like "A", "B", or "C") instead of explicit percentages, the system intelligently locates the corresponding tax rates in the summary section and associates them with the appropriate items.

Countries with Multiple Tax Rates

Several countries implement complex tax structures that result in multiple rates appearing on invoices:

European Union (VAT)

EU countries typically have standard, reduced, and super-reduced VAT rates:

In France: 20% (standard), 10% (reduced), 5.5% (super-reduced)

In United Kingdom: 20% (standard), 5% (reduced)

In Italy: 22% (standard), 11% (reduced), 10% (reduced), 5% (super-reduced), 4% (super-reduced)
