6. New vs Old — எது Choose பண்ணணும்?

  • Minimal deductions claim பண்றவங்க (no home loan, low 80C) — New Regime clearly better
  • ₹3.5-4 Lakh+ deductions claim பண்ணுறவங்க (80C ₹1.5L + HRA + Home Loan Interest ₹2L) — Old Regime still beneficial-ஆ இருக்கலாம்
  • Salaried, no home loan — New Regime பொதுவா better
  • Home loan + high HRA + full 80C — Old Regime calculate பண்ணி பாருங்க
💡 Golden Rule

எப்போவும் இரண்டு regime-லும் calculate பண்ணி compare பண்ணுங்க. Income Tax Department website-ல calculator இருக்கு, அல்லது CA/tax advisor-கிட்ட check பண்ணுங்க. Blanket rule இல்ல — உங்க specific deductions-ஐ பொறுத்தது.

7. Regime எப்படி Switch பண்றது?

  • Salaried individuals — ஒவ்வொரு வருஷமும் ITR file பண்ணும்போது regime switch பண்ணலாம் (unlimited times)
  • Business/Professional income உள்ளவங்க — switch பண்ண restrictions இருக்கு, one-time switch back option மட்டும்
  • Default — நீங்க specifically Old Regime select பண்ணலைன்னா, New Regime automatic ah apply ஆகும்
  • Employer-க்கு inform பண்ணணும் — TDS calculation-க்கு, year start-லேயே employer-கிட்ட உங்க preferred regime சொல்லுங்க

8. Surcharge & Cess

Income RangeSurcharge
Above ₹50 Lakh10%
Above ₹1 Crore15%
Above ₹2 Crore (New Regime)25% (capped)
Above ₹5 Crore (Old Regime only)37%

Health & Education Cess: 4% — total tax (including surcharge) மேல calculate ஆகும், both regimes-லும் applicable.

⚠️ New Regime Advantage

New Regime-ல max surcharge 25% (37% apply ஆகாது) — very high-income earners-ku (₹5 Crore+) இது oru additional benefit.

9. Common Mistakes

  • Old Regime deductions New Regime-ல் expect பண்றது — 80C, HRA, Home Loan Interest New Regime-ல கிடைக்காது (Employer NPS exception)
  • Regime compare பண்ணாம decide பண்றது — Both regimes-லும் calculate பண்ணாம oru decision எடுக்கக்கூடாது
  • ₹12L exact limit-ல் risk எடுக்கறது — ₹12,00,001 taxable income வந்தா rebate போயிடும், full tax apply ஆகும்
  • Business income உள்ளவங்க unlimited switch expect பண்றது — Restrictions இருக்கு, careful ah decide பண்ணுங்க
  • Employer-க்கு regime தெரிவிக்காதது — Wrong TDS deduct ஆகி, year-end refund claim பண்ணணும்
