To better understand the rules for offsetting capital losses
Solution
The numbers $5,500 ; $800 and $6,300 are arrived as follows:
In the year 2015:
STCG after setting off STCL of 2015 and 2014 is $1,500;
LTCL is $22,000 and LTCG is $12,000 only, there is shortage of $10,000 to set off LTCL, so STCG can be used to set it off, then there is $8,500. It is also known that, $3,000 can be set off against the ordinary income, then there would be $5,500 ($8,500 - $3,000) of LTCL to be carried forward.
In the year 2016:
STCG after setting off STCL is $1,500.
LTCG is $5,700 and LTCL carried forward is $5,500 and LTCL in 2016 is $5,500. LTCL after setting off STCG balance and LTCG is $3,800. It is also known that, $3,000 can be set off against the ordinary income, then there would be $800 ($3,800 - $3,000) of LTCL to be carried forward.
In the year 2017:
STCL after setting off against STCG is $2,000
LTCG is $3,500 out of which $2,000 can be set off against STCL, after which LTCG which can be set off against LTCL is $1,500. LTCL carried forward from 2016 is $800 and LTCL in 2017 is $10,000. LTCL remaining after setting it off against LTCG is $9,300. It is also known that, $3,000 can be set off against the ordinary income, then there would be $6,300 ($9,300 - $3,000) of LTCL to be carried forward.
