BTST Buy Today Sell Tomorrow and Tax-Loss Harvesting

Understanding Tax-Loss Harvesting

As the financial year approaches conclusion, income typically comprises both realised profits and unrealised losses. Without intervention, tax liability applies to profits earned, whilst loss recognition is deferred to the following year. This timing mismatch results in higher tax outflows, reducing capital available for reinvestment and potential returns.

One can defer tax payment by booking unrealised losses, then re-establishing the same position. This strategy reduces tax burden for the current year by offsetting gains with losses.

For FY 2024-25 (AY 2025-26): India lacks explicit regulation prohibiting tax-loss harvesting. In contrast, the United States classifies such practices as “wash sales,” disallowing the offsetting of realised gains through this mechanism within 30 days of the loss-making sale.

How Tax-Loss Harvesting Works:

Example for FY 2024-25:

Suppose you have:

Realised STCG of Rs 3,00,000 (already booked through sales)

Unrealised loss of Rs 1,20,000 in current holdings (market value declined but not sold)

Without action:

Tax on Rs 3,00,000 at 15% = Rs 45,000 (plus cess = Rs 46,800)

With tax-loss harvesting (before 31st March 2025):

Sell the loss-making holdings to book Rs 1,20,000 loss

Re-purchase the same securities immediately (or next day)

Net taxable STCG = Rs 3,00,000 – Rs 1,20,000 = Rs 1,80,000

Tax on Rs 1,80,000 at 15% = Rs 27,000 (plus cess = Rs 28,080)

Tax saved = Rs 18,720

Your new cost basis for the repurchased securities is the current market price, and you’ve preserved the same portfolio composition whilst reducing current year tax liability.

Important Considerations for FY 2024-25:

Transaction Costs: Factor in brokerage, STT, and other charges when deciding whether tax-loss harvesting is worthwhile

Documentation: Maintain clear records showing genuine transactions, not sham arrangements

Timing: Execute before 31st March 2025 to claim losses in FY 2024-25

Scrutiny Risk: Repeated buying and selling of identical securities multiple times within short periods may attract scrutiny

Advisory: Indian market participants are strongly advised to consult a Chartered Accountant before implementing tax-loss harvesting strategies, particularly for filing FY 2024-25 returns. This precaution avoids potential complications during tax assessments or scrutiny proceedings, particularly if identical shares have been repeatedly purchased and sold. The Income Tax Department may question transactions that appear designed solely to avoid tax without genuine commercial substance.

Best Practices for FY 2024-25:

Document the investment rationale for repurchasing the same security

Avoid excessive frequency (multiple times in the same security within the same year)

Maintain commercial substance—genuine transactions at market prices

Consider alternative securities in the same sector if concerned about scrutiny

Ensure sufficient time gap (at least 1-2 days) between sale and repurchase

For those engaged in equity investment through a stock broker or following trading calls based on market analysis, tax-loss harvesting represents a legitimate strategy for managing annual tax liability when executed properly. However, proper documentation and professional guidance ensure the approach withstands scrutiny from tax authorities.

BTST Classification: Speculative, Non-Speculative, or Short-Term Capital Gain?

For FY 2024-25 (AY 2025-26): Buy Today Sell Tomorrow (BTST) or Acquire Today Sell Tomorrow (ATST) transactions have gained considerable popularity amongst equity traders. These transactions involve purchasing shares with the intention of selling the following day (or within T+1/T+2 settlement period) without accepting delivery into the DEMAT account.

The absence of delivery raises the question: should BTST be classified as speculative, similar to intraday equity trading?

Current Tax Treatment Debate:

Two contrasting viewpoints exist on this matter:

View 1: Speculative Business Income

No physical delivery taken to DEMAT account

Intention to profit from short-term price movement

Similar in nature to intraday trading

Should be classified as speculative business income

Losses can only offset speculative gains

Carry forward for 4 years

View 2: Short-Term Capital Gain (Prevalent Practice)

STT is paid on BTST transactions by exchanges

Settlement occurs through recognised stock exchange mechanism

Technically, delivery does occur (through the settlement system), just not to your DEMAT

Should be treated as STCG

Taxed at 15% if STT paid

Losses can offset STCG and LTCG

Practical Guidance for FY 2024-25:

The tax treatment largely depends on frequency and pattern:

Occasional BTST Transactions (1-10 trades per year):

Generally acceptable to treat as Short-Term Capital Gain

Taxed at 15% (plus cess)

Less likely to attract scrutiny

File using ITR-2

Frequent BTST Trading (Regular pattern, high volume):

More prudent to classify as Speculative Business Income

Demonstrates a systematic business activity

Taxed as per income tax slab

File using ITR-3

Losses can only offset speculative gains

Income Tax Department’s Position:

While there’s no definitive circular specifically addressing BTST, the Income Tax Department’s approach during assessments has generally been:

STT payment is a key indicator for capital gains treatment

Frequency and volume matter significantly

Systematic profit-seeking through BTST may be viewed as business activity

Consistency in classification across years is important

Recommendation for FY 2024-25:

For investors utilising a stock screener to identify overnight opportunities or those participating in IPO allocations with short-term exit strategies (common in IPOs where shares are sold within 1-2 days of listing), the following approach is advisable:

If BTST is incidental to your investment activity:

Treat as STCG

File ITR-2

Maintain records showing STT payment

If BTST is your primary trading strategy:

Treat as speculative business income

File ITR-3

Maintain proper books of accounts

Consider audit implications if turnover exceeds thresholds

Grey Area Alert: BTST remains somewhat of a grey area in Indian tax law. The safest approach is to:

Maintain consistency once you’ve chosen a classification

Document your rationale for the chosen classification

Consult a Chartered Accountant before filing FY 2024-25 returns

Be prepared to justify your classification if questioned during assessment

Important Note on Recent Developments:

Some tax practitioners suggest that with the tightening of delivery-based classification rules and increased scrutiny on trading activities, the Income Tax Department may increasingly view systematic BTST as speculative business income rather than capital gains. For FY 2024-25 filing, err on the side of caution if your BTST activity is substantial.

Advance Tax Requirements for Business Income

For FY 2024-25 (AY 2025-26): Paying advance tax becomes mandatory when generating business income. As outlined previously, payments must be remitted annually according to a specified schedule: 15 percent by 15th June 2024, 45 percent by 15th September 2024, 75 percent by 15th December 2024, and 100 percent by 15th March 2025. These percentages apply to estimated annual income.

The fundamental question emerges: upon what figures are these percentages calculated?

Business income introduces inherent uncertainty. Whilst profits may appear substantial through September, assuming identical performance until the financial year’s conclusion proves unrealistic. Results could improve or deteriorate significantly.

Specific Challenges for Trading Business Income in FY 2024-25:

Volatile Markets: Market conditions can change dramatically, making profit estimation difficult

Lumpy Gains/Losses: A single large trade can significantly alter annual P&L

Seasonal Patterns: Some traders perform better in certain quarters

Changing Strategies: Trading approach may evolve during the year

Prudent Approach for FY 2024-25:

Rather than trying to estimate full-year business income at the start:

15th June 2024 Payment:

Estimate conservatively based on Q1 (April-May) performance

If profits are Rs 1,00,000 by May, estimate annual at Rs 6,00,000

Pay 15% of estimated tax on Rs 6,00,000

15th September 2024 Payment:

Re-evaluate based on April-August actual performance

Adjust estimate up or down

Ensure cumulative payment reaches 45% of revised estimate

15th December 2024 Payment:

Re-evaluate based on April-November actual performance

Make final adjustment to estimates

Ensure cumulative payment reaches 75% of revised estimate

15th March 2025 Payment:

By this point, you have 11 months of actual data

Pay balance to reach 100% of estimated tax

Interest for Non-Payment/Short-Payment:

Advance tax payment remains compulsory, with non-compliance attracting penalties:

Section 234B Interest: 1% per month on shortfall if total advance tax paid is less than 90% of assessed tax

Section 234C Interest: 1% per month for deferment calculated as:

If less than 12% paid by 15th June: 1% on shortfall for 3 months

If less than 36% paid by 15th September: 1% on shortfall for 3 months

If less than 75% paid by 15th December: 1% on shortfall for 3 months

Example Calculation for FY 2024-25:

Actual tax liability for FY 2024-25: Rs 2,00,000

Advance tax paid:

15th June 2024: Rs 20,000 (should be Rs 30,000, shortfall Rs 10,000)

15th September 2024: Rs 50,000 (cumulative Rs 70,000, should be Rs 90,000, shortfall Rs 20,000)

15th December 2024: Rs 80,000 (cumulative Rs 1,50,000, should be Rs 1,50,000, no shortfall)

15th March 2025: Rs 50,000 (cumulative Rs 2,00,000, 100% paid)

Interest calculation under 234C:

June shortfall: Rs 10,000 × 1% × 3 months = Rs 300

September shortfall: Rs 20,000 × 1% × 3 months = Rs 600

December: No shortfall, no interest

Total 234C interest = Rs 900

If total advance tax paid was less than Rs 1,80,000 (90% of Rs 2,00,000), additional interest under Section 234B would apply.

The optimal approach involves making partial payments throughout the year, progressively adjusting estimates. This provides clearer perspective on year-end obligations whilst minimising interest liability. Moreover, overpayment can be reclaimed through refunds from the Income Tax Department, which processes such requests with reasonable efficiency (typically 2-4 months after ITR processing).

Practical Tips for Trading Business Income in FY 2024-25:

Maintain a separate savings account for tax liability—transfer a portion of each profit immediately

Use conservative estimates initially—overpaying is better than underpaying

Track cumulative performance monthly to refine estimates

Set calendar reminders for advance tax dates

Keep digital copies of all advance tax challans for ITR filing

Consider professional help if annual turnover exceeds Rs 1 crore

For those managing significant trading activity in the stock market, whether through systematic equity investment strategies or active trading programmes guided by a financial advisor, maintaining advance tax compliance prevents unnecessary interest charges whilst ensuring capital remains optimally deployed. Resources at https://stoxbox.in/ offer comprehensive guidance on tax planning for various trading and investment scenarios, helping market participants navigate advance tax requirements efficiently whilst focusing on their primary objective—generating sustainable returns from stock market activities.

Critical Reminder for FY 2024-25: Unlike salaried individuals where TDS covers tax liability automatically, traders and investors with business income or substantial capital gains bear personal responsibility for advance tax compliance. The Income Tax Department’s systems now automatically detect trading activity through data from stock exchanges, making non-compliance easily detectable and subject to interest penalties.
