1. Trade Details and Calculations

March 1: Bought 500 shares at $20

Action: Buy
Shares: 500
Price per share: $20
Total cost: 500 × $20 = * *$ 10,000**
No gain or loss at this point.

March 2: Sold 500 shares at $10

Action: Sell
Shares: 500
Price per share: $10
Proceeds: 500 × $10 = * *$ 5,000**
Cost basis: $10,000 (from March 1 purchase)
Realized loss: $5, 000 -$ 10,000 = -$5,000

This is a realized loss of $5,000. However, we need to check if this loss is disallowed due to the wash sale rule.

Wash Sale Rule

The wash sale rule disallows a loss if you buy "substantially identical" securities within 30 days before or after the sale. In this case:

You sold 500 shares at a loss on March 2.
On March 5, you bought 200 shares of the same stock.

Since the March 5 purchase occurred within 30 days of the March 2 sale, the wash sale rule applies to the 200 shares bought on March 5. The disallowed loss is calculated as follows:

Disallowed loss: 200 shares × ( $20 -$ 10) = $2,000
Allowed loss: $5, 000 (t o t a ll oss) -$ 2,000 (disallowed loss) = $3,000

The disallowed loss of $2,000 is added to the cost basis of the 200 shares bought on March 5.

March 5: Bought 200 shares at $5

Action: Buy
Shares: 200
Price per share: $5
Total cost: 200 × $5 = * *$ 1,000**
Adjusted cost basis (due to wash sale): $1, 000 +$ 2,000 (disallowed loss) = $3,000

March 5: Sold 200 shares at $20

Action: Sell
Shares: 200
Price per share: $20
Proceeds: 200 × $20 = * *$ 4,000**
Adjusted cost basis: $3,000
Realized gain: $4, 000 -$ 3,000 = $1,000

March 10: Bought 100 shares at $20

Action: Buy
Shares: 100
Price per share: $20
Total cost: 100 × $20 = * *$ 2,000**
No gain or loss at this point.

March 10: Sold 100 shares at $25

Action: Sell
Shares: 100
Price per share: $25
Proceeds: 100 × $25 = * *$ 2,500**
Cost basis: $2,000
Realized gain: $2, 500 -$ 2,000 = $500

2. Summary of Gains/Losses

Allowed loss from March 2 sale: -$3,000
Gain from March 5 sale: $1,000
Gain from March 10 sale: $500

3. Total Taxable Income

Net gain/loss: - $3, 000 +$ 1,000 + $500 = * * -$ 1,500**
This is a **net loss of $1, 500 * *, w hi c h c anb e u se d t oo ff se t o t h erc a p i t a l g ain sor u pt o$ 3,000 of ordinary income for the year.

4. Wash Sale Impact

The wash sale rule disallowed $2, 000 o f t h e l oss f ro m t h e M a rc h 2 s a l e . T hi s$ 2,000 was added to the cost basis of the 200 shares bought on March 5, reducing the gain on the March 5 sale.

Final Answer

Allowed loss: $3,000 (from March 2 sale)
Gains: $1, 000 (M a rc h 5) +$ 500 (March 10) = $1,500
Net taxable loss: -$1,500
Wash sale disallowed loss: $2,000 (added to cost basis of March 5 purchase).

• 謝謝啊。也是這麽算的。就是整個loss之後，買回來一部分盈利了，剩下的就成了allowed loss? -害怕- ♂ (96 bytes) () 01/22/2025 postreply 15:29:59

• 這個deepseek明顯沒有理解樓主的最後一句話。disallowed loss根本不存在了。chatgpt才是對的。 -lanyin0314- ♂ (106 bytes) () 01/22/2025 postreply 15:36:12
