New vs Old Tax Regime — Slabs, Rebate Aur Deductions

FY 2026-27 mein new tax regime default hai — lower slab rates lekin most deductions (80C, HRA, home loan interest) available nahi hain. Old regime mein deductions milte hain lekin rates thodi zyada hain. Naye regime mein ₹12 lakh tak income par Section 87A rebate se effectively zero tax ban jaata hai; old regime mein ye limit sirf ₹5 lakh hai.

ITR Filing — Kaunsa Form, Due Date Aur Belated/Revised Return

Sahi ITR form choose karna filing ka sabse pehla step hai — salary-only income ke liye ITR-1, capital gains/multiple properties ke liye ITR-2, business/professional income ke liye ITR-3/ITR-4. AY 2026-27 ke liye forms mein kuch changes bhi aaye hain (2 house properties allowed ab ITR-1/4 mein bhi). Agar due date miss ho jaaye, belated return file kar sakte hain — late fee ke saath.

Advance Tax Aur Form 26AS/AIS/TIS Reconciliation

Agar net tax liability ₹10,000 se zyada hai, advance tax 4 instalments mein pay karna hai — miss karne par interest lagta hai. ITR file karne se pehle Form 26AS (tax credits), AIS (broad transaction data) aur TIS (AIS summary) teeno ko reconcile karna zaroori hai taaki koi income miss na ho aur notice ka risk kam ho.

Capital Gains Aur HUF — Investment Aur Family Tax Planning

Shares/mutual funds par STCG flat 20% lagta hai (≤12 months), aur LTCG 12.5% ₹1.25 lakh se upar (>12 months) — ye exemption annual aur aggregate hai, per-investment nahi. HUF (Hindu Undivided Family) apna alag basic exemption aur most deductions claim kar sakta hai, lekin sirf legitimate HUF income (ancestral property, non-member gifts) par — salary kabhi HUF ko nahi ja sakti.

Freelancers Aur Professionals — Presumptive Taxation Aur Tax Audit

Specified professionals (CA, doctor, engineer, IT consultant, etc.) Section 44ADA ke under gross receipts ka 50% taxable income declare kar sakte hain — ₹50 lakh standard limit, ₹75 lakh agar 95%+ receipts banking channels se aaye hon. Isse kam declare karne par books maintain karna aur tax audit (Section 44AB) mandatory ho jaata hai. Detail mein: 44ADA Presumptive Taxation Guide aur Tax Audit Section 44AB — Applicability.
