RBI Bulletin Oct 2026: New IT Act Rules for Indian Taxpayers

What Happened?

The Reserve Bank of India's October 2026 Bulletin has issued critical guidance on monetary policy coordination and its tax implications under the new Income Tax Act 2025. While primarily focused on RBI's policy stance, this bulletin contains specific references to updated tax compliance procedures, digital payment tracking, and TDS (Tax Deducted at Source) requirements that affect salaried employees, businesses, and financial institutions for Assessment Year 2026-27. The bulletin emphasizes stricter documentation norms for foreign remittances and enhanced reporting obligations for high-value transactions.

Background & Legal Context

The Income Tax Act 2025 introduced several amendments to the 1961 Act, particularly in sections dealing with:

• Section 194A (Interest Income) — TDS on interest from banks and post office now starts at ₹40,000 (earlier ₹10,000). The RBI Bulletin October 2026 emphasizes that banks must implement this change for all interest credits from October 1, 2026 onwards.
• Section 195 (Foreign Remittances) — Enhanced documentation requirements for remittances abroad. The IT Act 2025 now mandates Form 15CA and Form 15CB submission even for routine salary remittances by NRIs, effective immediately.
• Section 206C (TCS on Sales) — Tax Collected at Source on high-value e-commerce transactions has expanded. From October 2026, TCS applies to online sales above ₹30 lakh per financial year (earlier ₹50 lakh).
• Section 139 (Returns) — The Act 2025 mandates digital filing only for businesses with turnover above ₹1 crore. No paper returns accepted from AY 2026-27.
• Section 80D & 80U (Medical Deductions) — New limits introduced: ₹1 lakh for individuals below 60 years, ₹2 lakh for senior citizens. These are final limits under Act 2025.

The RBI Bulletin specifically notes that monetary policy transmission depends on compliant taxpayer behavior and urges all financial institutions to strictly implement these IT Act 2025 provisions without deviation.

What Does This Mean for You?

For Salaried Employees: Your interest income from savings accounts and fixed deposits will now have TDS deducted from October 2026 if annual interest exceeds ₹40,000. This is a significant change from the previous ₹10,000 threshold under the 1961 Act. If you have multiple bank accounts, the TDS might be triggered faster. You should monitor your interest credits and request your bank to not deduct TDS if your overall income is below the taxable limit (submit Form 15G or 15H immediately to avoid this).

For Business Owners: If your annual turnover is above ₹1 crore, you must file returns digitally only from AY 2026-27. No physical or paper returns will be accepted. The IT Act 2025 has removed the option entirely. Additionally, TCS on your e-commerce sales has tightened — if you sell goods worth ₹30 lakh or more in a financial year, buyers must deduct 1% TCS at the point of transaction. This means your cash flows will be reduced by TCS amounts.

For NRIs and Foreign Remitters: The RBI Bulletin emphasizes that any remittance abroad now requires Form 15CA signed by a CA and Form 15CB (if amount exceeds ₹1 lakh). Even routine salary remittances cannot skip this. Violations under Section 195 can attract penalties up to ₹10,000 plus prosecution risk under Section 271G of the IT Act 2025.

For Medical Expense Claimants: If you were claiming ₹1.5 lakh or ₹2.5 lakh deduction for health insurance under Section 80D in previous years, the IT Act 2025 has capped this at ₹1 lakh (below 60 years) and ₹2 lakh (senior citizens). Your tax savings will reduce from AY 2026-27. Plan your health insurance premiums accordingly.

For Financial Institutions: Banks and financial entities must implement TDS changes on interest from October 1, 2026 immediately. The RBI Bulletin warns that non-compliance will trigger regulatory action and penalties. Your Form 26AS (tax credit statement) must reflect accurate TDS information.

What Should You Do Now?

Immediate Actions (October-November 2026):

• Salaried Employees: Approach your bank and submit Form 15G (if income is below taxable limit) to prevent TDS on interest. Collect all interest statements from all bank accounts and consolidate them.
• Business Owners: If turnover exceeds ₹1 crore, ensure your accountant is trained in digital filing using the CBDT's e-filing portal. Download and install the latest tax compliance software that supports IT Act 2025 formats.
• NRIs: For any pending remittances, engage a Chartered Accountant immediately to prepare Form 15CA and Form 15CB. Do not remit money without these forms — it's a violation of Section 195 and invites penalties.
• Medical Deduction Claimants: Review your health insurance policies and medical expense claims. If you were claiming more than the new cap, restructure your claims under Section 80D for AY 2026-27. Consider claiming spouse/children deductions separately to maximize total benefit.
• E-Commerce Sellers: Audit your annual sales figures. If sales will cross ₹30 lakh, inform your buyers about TCS implications. Update your invoices to mention TCS separately. Reconcile TCS received with your Form 26AS monthly.

Compliance Checklist:

• Update PAN details if not linked to Aadhaar by October 2026 (Section 139AA, IT Act 2025).
• Maintain original digital copies of all income documents — the 2025 Act mandates 6-year digital retention.
• If you have multiple incomes (salary + interest + business), file ITR-2 or ITR-3 form digitally only from October 2026.
• Download and maintain your updated Form 26AS showing revised TDS credits from all deductors.

Key Takeaways

• TDS on Interest Lowered Threshold: Interest TDS now starts at ₹40,000 (not ₹10,000), affecting bank depositors immediately from October 1, 2026. File Form 15G if eligible.
• Foreign Remittance Rules Tightened: All remittances abroad require Form 15CA and Form 15CB under Section 195 (IT Act 2025). Non-compliance invites ₹10,000 penalty.
• Digital Filing Mandatory: Businesses with ₹1 crore+ turnover cannot file paper returns from AY 2026-27. Only e-filing is allowed under Section 139.
• TCS Threshold Reduced for E-Commerce: Sales above ₹30 lakh now trigger 1% TCS (earlier ₹50 lakh). This reduces your cash inflows immediately.
• Medical Deduction Caps Finalized: Section 80D benefits capped at ₹1 lakh (below 60 yrs) and ₹2 lakh (senior citizens). Cannot claim beyond these limits under IT Act 2025.

Bottom Line: The RBI Bulletin's October 2026 update signals stricter tax compliance across all sections. Whether you're earning interest, remitting money abroad, selling online, or claiming medical deductions, the IT Act 2025 changes directly impact your tax liability and compliance burden. Start implementing these changes now to avoid penalties and interest under Sections 221, 222, and 271G of the IT Act 2025.
