Section 87A Calculator: Rebate & Marginal Relief (2026-27)

Last Updated: May 7, 2026 | Verified for AY 2027-28

Quick Summary: Section 87A Rebate & Relief

In FY 2026-27 (New Tax Regime), you pay ZERO tax if your taxable income is up to ₹12,00,000. If your income is between ₹12,00,001 and ₹12,77,500, you are eligible for Marginal Relief, which prevents your tax from exceeding your extra income.

Zero Tax Limit: ₹12 Lakhs

Standard Deduction: ₹75,000

Tax Trap Zone: ₹12.01L - ₹12.77L

In the New Tax Regime (FY 2026-27), Section 87A provides a full rebate for taxable income up to ₹12 Lakhs. However, crossing this limit triggers a 'Cliff Effect' where your tax can exceed your extra income. Marginal Relief caps this tax at the excess income earned, but after adding the 4% cess, you effectively pay a 104% marginal tax until the breakeven point (approx ₹12.77L).

Example Scenario: The ₹12.75 Lakh Income Trap

Under the new tax regime (FY 2026-27), Section 87A provides a rebate that effectively makes taxable income up to ₹12 lakh tax-free. However, the way this rebate is withdrawn creates a unique financial phenomenon known as the "Tax Cliff."

The ₹12,85,000 Gross Income Shock

Suppose you get a ₹10,000 bonus, taking your gross income from ₹12,75,000 to ₹12,85,000.

Old Salary: ₹12.75L Gross - ₹75k Std. Ded. = ₹12L Taxable. Tax: ₹0.
New Salary: ₹12.85L Gross - ₹75k Std. Ded. = ₹12.10L Taxable.
Base Tax: ₹42,000 (as per slabs).
Marginal Relief: Capped at excess income (₹10,000). Tax becomes ₹10,000.
Final Tax: ₹10,000 + 4% Cess = ₹10,400.

Outcome: You earned ₹10,000 extra but paid ₹10,400 in tax. Your net take-home salary actually DECREASED by ₹400!

This table shows how your tax liability explodes the moment you cross the ₹12 Lakh taxable threshold. Note the "Negative Return" zone where earning more results in less money in hand.

Gross Income	Taxable Income	Base Tax	Marginal Relief	Final Tax	Status
₹12,75,000	₹12,00,000	₹0	₹0	₹0	✅ Zero Tax Zone
₹12,85,000	₹12,10,000	₹42,000	₹32,000	₹10,400	⚠️ 104% Tax Trap
₹13,12,500	₹12,37,500	₹48,750	₹11,250	₹39,000	🛑 Peak Relief Zone
₹14,00,000	₹13,25,000	₹67,500	₹0	₹70,200	📈 Normal Slabs

3 Pro-Tips to Avoid the 87A Tax Cliff

1. Employee NPS (80CCD-2)

In the New Regime, your employer's contribution to your NPS (up to 10% of salary) is still deductible. Use this to pull your taxable income back below ₹12 Lakhs.

2. Strategic Bonus Timing

If a small bonus is pushing you into the ₹12.1L - ₹12.5L zone, consider requesting a deferral or diverting it to exempt allowances if possible under your HR policy.

3. Standard Deduction is Key

Remember that the ₹75,000 Standard Deduction is your best friend. Your actual "Safe Gross Income" is ₹12,75,000, not just ₹12,00,000.
