Tax Rates — Individuals & HUF

Assessment Year 2026-27 (FY 2025-26)

Two regimes
The new regime under section 115BAC is the default. The old regime is optional and must be opted into (and, for those with business income, Form 10-IEA applies). Most deductions and exemptions are unavailable under the new regime.

New regime — section 115BAC (default)

Maximum 87A rebate
Rebate & marginal relief (new regime)
Resident individuals with total income up to ₹ 12,00,000 pay nil tax (rebate u/s 87A up to ₹ 60,000). Just above ₹ 12 lakh, marginal relief caps the tax so it does not exceed the income over ₹ 12 lakh. With the ₹ 75,000 standard deduction, a salaried person is effectively tax-free up to ₹ 12,75,000.

Standard deduction ₹ 50,000; rebate u/s 87A up to ₹ 12,500 where total income does not exceed ₹ 5,00,000. Chapter VI-A deductions (80C, 80D, etc.), HRA and home-loan interest remain available.

Surcharge on income-tax

Above ₹ 1 crore – ₹ 2 crore15%15%
Above ₹ 2 crore – ₹ 5 crore25%25%
Above ₹ 5 crore37%25% (capped)
Surcharge — watch points
Surcharge attracts marginal relief at each threshold. The surcharge on dividend income and on capital gains u/s 111A/112A/112 is capped at 15%. Under the new regime the highest surcharge is 25%. Health & education cess @ 4% applies on tax plus surcharge in every case.
Quick example (new regime)
Total income ₹ 16,00,000 (after standard deduction): tax = 5% of 4L + 10% of 4L + 15% of 4L = ₹ 1,20,000, plus 4% cess = ₹ 1,24,800.

From 1 April 2025, a firm/LLP must deduct TDS @ 10% on salary, remuneration, interest, commission or bonus paid to a partner where the aggregate exceeds ₹ 20,000 in the year.
Alternate Minimum Tax (AMT)
Where a firm/LLP claims specified deductions (e.g. Chapter VI-A Part C, s.10AA), AMT @ 18.5% (plus surcharge/cess) of adjusted total income applies u/s 115JC. AMT credit may be carried forward for 15 years. LLPs cannot opt for the lower company regimes.

MAT vs AMT
MAT (s.115JB) applies to companies at 15% of book profit where it exceeds regular tax (not for 115BAA/BAB). AMT (s.115JC) applies to non-corporates claiming specified deductions, at 18.5% (15% for co-operatives) of adjusted total income. Both generate a credit carried forward for 15 years; both attract surcharge and 4% cess.
Opting in
The lower company/co-operative regimes are irreversible once opted (Form 10-IC / 10-ID / 10-IF). Individuals with business income switching to the old regime use Form 10-IEA.

2Tax on (agricultural income + basic exemption limit)
3Tax payable = Step 1 − Step 2 (plus cess)
What qualifies

A 48-month second chance
The Finance Act 2025 extended the window to file an updated return from 24 to 48 months from the end of the relevant assessment year (effective 1 April 2025). For AY 2025-26, ITR-U may be filed up to 31 March 2030.

Additional tax payable — section 140B [s.267]

Filed within (from end of AY)Additional tax (on tax + interest)
12 months25%
12 – 24 months50%
24 – 36 months60%
36 – 48 months70%
ITR-U can only go UP
An updated return cannot reduce tax, claim or increase a refund, or be filed where it shows a loss return (subject to the limited Budget 2026 relaxation for reducing a carried-forward loss). It is blocked where a search, survey or seizure has occurred, or assessment/reassessment is pending, and can be filed only once per AY.
Compute the full cost first
Pay the regular tax, interest u/s 234A/B/C, and the additional tax via Challan 280 (code 300) before filing — ITR-U is invalid without proof of payment. File the relevant ITR form alongside ITR-U.

AIS & TIS

Annual Information Statement / Taxpayer Information Summary

Reconcile before filing
The AIS consolidates information reported to the department — TDS/TCS, interest, dividend, securities and mutual-fund transactions, foreign remittances, SFT data and more. The TIS presents an aggregated, category-wise summary used for pre-filling the return.
Feedback
Where an entry is incorrect, duplicated or relates to another person, submit feedback in the AIS. Always reconcile the AIS/TIS and Form 26AS with your books before filing to avoid mismatches and notices.

Transition & Planning

Income-tax Act 1961 ↔ 2025

The transition

A new code from 1 April 2026
The Income-tax Act, 2025 replaces the 1961 Act with effect from 1 April 2026. It is shorter (about 536 sections) and introduces the single concept of 'Tax Year' in place of 'previous year' and 'assessment year'. Returns for FY 2025-26 (AY 2026-27) are still filed under the 1961 Act.

Financial Planning Guide

General principles

  • Emergency fund — keep 6–12 months of expenses in liquid form before investing
  • Protection first — adequate term life cover and family health insurance
  • Tax-efficient saving — use EPF/PPF/NPS/ELSS within goals, not merely for deduction
  • Asset allocation — balance equity, debt and gold to risk appetite and horizon
  • Retirement — start early; NPS adds the 80CCD(1B) benefit under the old regime
  • Estate hygiene — maintain nominations and a will across bank, demat and property
