The Challenge

Tax compliance in Bangladesh often involves navigating complex regulations and lengthy legal documents. Many businesses and individuals face challenges such as:

• Difficult VAT and tax calculations
• Lack of accessible digital tools tailored to Bangladesh regulations
• Complicated legal documents that are hard to search and reference
• Limited awareness of recent amendments and regulatory updates

For entrepreneurs, tax professionals, and even students studying law or finance, finding accurate and structured information can be time-consuming.

At Code & Cognition, we identified an opportunity to build technology-driven solutions that make tax knowledge easier to access and understand.

The Solution

To solve these problems, we developed two complementary digital products that work together to simplify both tax workflows and legal research.
