FAQ
Common questions, answered.
What's the Diwali to March 31 tax planning window?
5 months of intensive year-end planning. November-December: compliance deadlines (TP audit, MGT-7, PAS-6, MSME-1, Q3 advance tax, GSTR-9, Form ODI APR). February: pre-Budget. March: last-mile Section 80C/80D/80G + Section 54 reinvestment + Q4 advance tax. Final decisions before FY ends 31 March 2027.
Should I buy ELSS before Diwali or in March?
Both work. Diwali-based ELSS SIP spreads cost. March-based lump-sum optimises timing based on actual annual tax position. For most individuals: SIP throughout year + top-up in March to hit INR 1.5 lakh Section 80C limit.
How to time Section 54 reinvestment?
If LTCG realised in current FY: reinvestment window is 2 years forward (purchase) / 3 years forward (construction). Deposit in Capital Gain Account Scheme (CGAS) by 31 July 2027 if actual investment delayed. Must complete investment within 2/3 year window from original sale date.
New or Old regime for AY 2027-28?
Varies by deduction profile. For individuals with substantial deductions (HRA + home loan interest + Section 80C + 80D + 80G), old regime typically better. For simpler profile (minimum deductions), new regime often better due to lower rates + INR 7 lakh rebate. Use BQP calculator at bharatquantumprospera.com/new-vs-old-tax-regime-calculator.html.
What's the biggest Diwali-season compliance miss BQP sees?
Director DIR-3 KYC catch-up (missed 30 September deadline, deactivated DIN blocking all MCA filings). Fix urgently with INR 5,000 late fee + 24-72 hour reactivation. Also: PAS-6 half-year (29 November) + MSME Form I (29 November) often missed.
