If you manage the financial operations of a large company, multinational corporation (MNC), or foreign institutional investor (FII), this is the biggest change in 2026. The central government is now moving towards making fully automated tax filing and compliance mandatory for large taxpayers.
The government has opened API (Application Programming Interface) access to its tax portal to third-party developers. This means that you no longer have to spend hours navigating government websites to file taxes or respond to notices; your accounting software will automatically integrate with the government system and handle all the work.

After GST, Now Direct Taxes
The government had already granted API access to the Goods and Services Tax (GST) system, which provided significant relief to companies. Now, the news is that this door is also going to be fully opened for the Central Board of Direct Taxes (CBDT) and Customs. Experts believe that this significant step will enable consulting firms and tech companies to create advanced tools based on Artificial Intelligence (AI) that will calculate and file your tax liability without any manual intervention.
This change is also significant because currently, large companies have to access multiple government portals for GST notices, income tax returns, dispute resolution, and customs tracking. Now, all this data will be synced on a single platform.

Manual Filing Will End
Even though most returns are filed online these days, many processes, such as tracking tax appeals, are still largely manual. According to government sources, the APIs being released will transform the entire definition of tax compliance. This process will now be completely technology-driven.
For example, when an appeal is filed with the Income Tax Appellate Tribunal (ITAT), taxpayers have to repeatedly check the tribunal’s website for updates. But now, through API-based integration, all such updates will be delivered directly to the company’s internal system (ERP) at lightning speed.

AI and APIs
When direct access to government data is combined with AI tools, it will drive unprecedented digital transformation. These APIs allow large taxpayers to connect their internal accounting systems directly with the government’s tax ecosystem. Consultants will now use AI to create systems that require minimal human input.
In the case of GST, APIs already allow companies to monitor the MSME status of their vendors. This makes it incredibly easy to comply with special rules, such as paying MSME dues within 45 days. With this same feature now available in Direct Tax and Customs, the path to end-to-end automation has been paved for companies.

Benefits for Large Taxpayers
This new system will bring several significant changes. The primary benefit will be direct and secure data exchange between the ERP and the tax portal. Second, automatic notice alerts will be provided, and the system will automatically assist in drafting responses.

Furthermore, streamlined and real-time monitoring of tax appeals and court proceedings will be possible. Automated verification of vendors’ tax status will also reduce the risk of incorrect Input Tax Credit (ITC). Most importantly, the absence of manual entry will reduce the likelihood of human error to almost zero.
