Terms of service

01 Agreement and acceptance

By accessing or using the RegInfra API, website, or any associated services (collectively, "the Service"), you agree to be bound by these Terms of Service ("Terms"). If you are accessing the Service on behalf of a company or other legal entity, you represent that you have the authority to bind that entity to these Terms.

If you do not agree to these Terms, you must not access or use the Service.

RegInfra is operated by its founders ("we", "us", "RegInfra"). The Service is currently in beta and subject to change. These Terms apply to all users, including free trial users, paid subscribers, and integration partners.

02 Description of service

RegInfra provides a Tax Deducted at Source (TDS) compliance reasoning API built for the Indian market and compliant with the Income Tax Act 2025 (effective 1 April 2026). The Service calculates applicable TDS rates and amounts, stores decision reasoning per transaction, and returns structured audit-ready responses.

Current capabilities include TDS calculation and decision storage for 19 sections under the Income Tax Act 2025. Additional sections and features may be added over time.

03 Permitted use

You may use the Service solely for lawful business purposes related to TDS compliance in India. Permitted uses include:

• Integrating the API into your internal payment or accounting systems to calculate TDS at the time of vendor payment
• Storing and retrieving TDS decision records for your own business transactions
• Using the API response as a reference for your own TDS deduction and filing processes
• Evaluating the Service during a free trial for the purpose of deciding whether to subscribe

04 Prohibited use

You must not use the Service in any of the following ways:

• Reselling, sublicensing, or white-labelling the Service to third parties without written permission from RegInfra
• Using the Service to process transactions on behalf of clients or third parties as a bureau or managed service without a separate agreement
• Attempting to reverse-engineer, scrape, or extract the underlying rule logic, rate tables, or decision models
• Sending requests that exceed your plan's rate limits through automated means intended to circumvent controls
• Using the Service for any unlawful purpose or in violation of applicable Indian law
• Submitting false, fabricated, or test data to the production API environment
• Sharing API keys with parties outside your organisation

05 No warranty on tax accuracy — important

We make reasonable efforts to keep our rule engine updated with current law, including the Income Tax Act 2025 and applicable Finance Acts. However, we do not warrant that every output is correct for your specific factual circumstances, that the Service reflects the most recent CBDT circulars at the exact moment of your request, or that the Service is a substitute for professional tax advice.

You remain solely responsible for the accuracy of your TDS deductions, filings, and payments. RegInfra shall not be liable for any tax demand, interest, penalty, or notice arising from reliance on the Service's outputs without independent professional verification.

06 API keys and account security

Access to the Service requires an API key issued by RegInfra. You are responsible for keeping your API key confidential, all API calls made using your key, and notifying us immediately at contact@reginfra.com if you suspect your key has been compromised.

RegInfra reserves the right to revoke or rotate API keys at any time in response to security concerns, abuse, or non-payment.

07 Rate limits and fair use

Each subscription plan carries a monthly API call limit and a per-minute rate limit.

Requests exceeding the per-minute rate limit will receive a 429 response. We reserve the right to suspend access for patterns of use that are abusive or materially exceed plan limits.

08 Data handling and privacy

When you use the Service, we store the transaction identifiers, amounts, and dates you provide, PAN numbers (masked in logs), the TDS decision output and reasoning chain, and your API key identifier for attribution.

We do not sell your data to third parties. Transaction data is stored in a PostgreSQL database hosted on Render (Singapore region) with encrypted connections.

You are responsible for ensuring that any PAN numbers or personal data you submit are handled in accordance with applicable Indian data protection laws.

09 Service availability

We target reasonable uptime and monitor the Service continuously. However, we do not guarantee any specific uptime SLA during the beta period. We will communicate planned maintenance windows in advance via email where possible.

10 Payment and cancellation

Paid plans are billed monthly in advance in Indian Rupees. Unused API calls do not carry over to the next billing period.

You may cancel your subscription at any time by contacting us at contact@reginfra.com. Cancellation takes effect at the end of the current billing period. We do not offer pro-rated refunds for partial months unless agreed otherwise.

RegInfra reserves the right to change pricing with 30 days' written notice to existing subscribers.

11 Termination

RegInfra may suspend or terminate your access if you breach these Terms, fail to pay outstanding amounts, your use poses a security or legal risk, or we discontinue the Service.

Upon termination, you may request an export of your transaction data within 30 days by contacting us at contact@reginfra.com.

12 Limitation of liability

To the maximum extent permitted by applicable law, RegInfra and its founders shall not be liable for any indirect, incidental, special, or consequential damages, or any tax demand, penalty, or enforcement action arising from your use of the Service.

Our total aggregate liability for any claim shall not exceed the total fees paid by you to RegInfra in the three months preceding the claim.

13 Intellectual property

All intellectual property in the Service belongs to RegInfra. You receive a limited, non-exclusive, non-transferable licence to use the Service as described in these Terms. You retain ownership of your own transaction data.

14 Governing law and disputes

These Terms are governed by the laws of India. Any dispute shall be subject to the exclusive jurisdiction of the courts in Mumbai, Maharashtra, India.

Before initiating any legal proceedings, you agree to attempt to resolve disputes informally by contacting us at contact@reginfra.com.

15 Changes to these terms

We may update these Terms from time to time. Material changes will be communicated to registered users by email at least 14 days before they take effect. Your continued use of the Service after the effective date constitutes your acceptance of those changes.

The current version is always available at reginfra.com/terms.

16 Section 206AB — data reliance disclosure

The Service's 206AB applicability check is based on the information you provide in the API request — specifically the is_206ab_applicable field. RegInfra does not independently query the TRACES portal.

You are responsible for maintaining accurate and current 206AB status for each vendor in your systems and updating this status after the annual list refresh (typically post July 31 each year).
