India's large taxpayers, ranging from corporations and multinational companies to foreign institutional investors, may soon transition to near-fully automated tax compliance as the central government expands Application Programming Interface (API) access across its tax administration systems.
According to sources aware of the development, the government has already enabled API access for Goods and Services Tax (GST) platforms, while similar access for direct taxes administered by the Central Board of Direct Taxes (CBDT) and customs systems is expected in the next phase.

Single-System Compliance Likely for Corporates
Industry experts say the move could significantly reduce compliance friction for large enterprises that currently operate across multiple government portals to track returns, notices, assessments and litigation under GST, income tax and customs laws.
Although most tax filings are already digital, several backend processes-such as appeal tracking, notice monitoring and litigation management-continue to require manual follow-ups due to the lack of system integration.
Queries sent to the finance ministry on the proposed rollout did not receive a response.
APIs to Enable AI-Led Tax Management
Government provided APIs allow authorised third parties, including consulting firms and tax-technology providers, to directly connect corporate accounting systems with official tax portals. Experts believe this will enable AI-based compliance tools capable of automating filings, validations and status monitoring with minimal human involvement.
"These APIs fundamentally change how tax compliance is managed," said a person familiar with the matter. "Large taxpayers can integrate government systems directly into their internal workflows, while consultants can overlay AI to create intelligent, self-monitoring compliance frameworks."
For example, once an appeal is filed before the Income Tax Appellate Tribunal (ITAT), taxpayers currently need to manually check tribunal websites for updates. API integration could allow such updates to be pushed automatically into enterprise dashboards, eliminating repetitive checks.
GST APIs Already Delivering Results
Under GST, APIs are already being used by companies to:
- Track vendor MSME classification
- Ensure compliance with rules mandating payment to MSMEs within 45 days
- Automate reconciliations and vendor-level compliance checks
Customs compliance is also expected to benefit substantially. The customs ecosystem has traditionally suffered from limited integration with GST systems, particularly affecting businesses involved in import-export activities.
Toward Real-Time Tax Governance
For large taxpayers, the government's API initiative could mark a decisive shift from fragmented, manual compliance processes to centralised, system-driven tax governance. Experts say that once implemented across all major tax regimes, the framework could significantly enhance compliance accuracy, transparency and response times.
