/ Old regime

Full deduction suite.

Rates: 0% up to INR 2.5L / 5% from 2.5-5L / 20% from 5-10L / 30% above 10L.
Section 87A rebate: full tax rebate for income up to INR 5 lakh (effective zero tax).

Section 24 home loan interest: INR 2 lakh deduction (self-occupied) or unlimited (let-out).
Section 80TTA savings interest INR 10K + Section 80TTB senior INR 50K.
Section 80E education loan interest (no upper limit).
Section 80CCD(1B) NPS additional INR 50K.

/ Decision framework

Choose based on actual deductions.

Rule of thumb: new regime better if your total deductions (80C + 80D + 80G + HRA + home loan interest + specific others) are LESS than approximately INR 3.5 - 4 lakh. Old regime better if deductions exceed that threshold.

Specific scenarios where old regime wins:

HRA receiver with high rent in metro: HRA exemption often INR 2-5 lakh alone.
Home loan borrower: Section 24 interest INR 2 lakh + Section 80C principal INR 1.5 lakh.
Health insurance self + senior parents: Section 80D INR 1 lakh.
Combined with Section 80G donations + Section 80E education loan.

Specific scenarios where new regime wins:

Young professional with minimal deductions.
Rental income (no HRA + no home loan).
Simple PPF-only investment with no health insurance / donations.
Variable income years where Section 80C target not met.
Specific income types below INR 7 lakh (87A rebate zero tax).

/ Switch between regimes

Flexibility rules.

Non-business income: can switch between new + old each year. Choose per FY based on actual deduction profile.
Business income (Section 44AA books of accounts): once opted out of new regime, can switch back only ONCE in lifetime. Section 115BAC(5) proviso. Significant restriction.

FAQ

Common questions, answered.

Is new or old regime default?

New regime is default from AY 2024-25 (FY 2023-24 onwards). Must explicitly opt INTO old regime via Form 10-IEA (for business income) or at ITR filing (for non-business). Non-choice = new regime applied.

Can I switch regimes every year?

For non-business income: yes - switch each year based on actual deduction profile. For business income (Section 44AA books of accounts): once opted out of new regime, can switch back only ONCE in lifetime. Significant restriction - decide carefully.

What's the typical breakeven between regimes?

Approximately INR 3.5 - 4 lakh of total deductions (80C + 80D + 80G + HRA + home loan interest + specific). Below this: new regime typically wins. Above this: old regime typically wins. Specific calculation depends on actual income + specific deductions.

Does new regime allow Section 80CCD(2) employer NPS?

Yes - Section 80CCD(2) deduction for employer NPS contribution allowed in new regime (specific carve-out). This is one of the few deductions preserved in new regime, alongside standard deduction INR 75K + Section 10(10) gratuity + specific exemptions.

Can I use HRA in new regime?

No - HRA exemption under Section 10(13A) NOT available in new regime. If you receive HRA + pay rent + want HRA exemption: must opt into old regime. For salaried with high rent + no home loan, old regime typically wins.
