    It’s no revelation how many of us trust the power of the mobile to make quick transactions through mobile banking and UPIs. But when it comes to the tax return, we seek a fully reliable and confidential channel to operate through.

    Need of COTAX?

    The COTAX app, with its easy interface, makes tax returns extremely simple for those who are on the go. With a single tap, a user can upload their details & their Income Tax Return can be filed in under 7 minutes.


    During the development, the major challenge was maintaining the security over the platform as the user was using this platform to file the tax return where they share the confidential document with admin to prepare their tax that user has to file according to the income and wealth and other related documents. And apart from this, from the user's side, it was never easy to trust any platform and share the details easily until or unless you win the trust of the users.

What We Did?

  • Based on customer-centric methodology and confidentiality should be preserved well philosophy, we built a robust, innovative, and powerful Tax Return mobile app.

  • Using modern tech-stacks & robust development skills, our team has developed this mobile app that helps our client run their business and grab a large user base.

  • We collaborated with our client & understood their pain-point of the audience and Customized, highly intuitive designs to provide a flawless user experience.

  • For the pricing and packages, there are outstanding Integrated payment gateways effectively and make the application proceed smoothly.

  • New, advanced, and the most secure digital way to perform tax return process performed using latest technology, robust backend development & incredibly fast global deployment process.

The Result & Features

Maintaining the quality check and security method that we planned during the project's development helped us achieve the desired result, which was catered to us as the business requirements of the project. With the launch of the product, we have seen impressive app installs.
