Final answer:
The amount of Tatoo's capital loss carryover remaining after applying the carryback is $4,700.
Step-by-step explanation:
The amount of Tatoo's capital loss carryover remaining after it applies the carryback can be calculated by subtracting the net capital gains from the net capital losses over the years.
- Net capital loss in 2018: $13,000
- Net capital gain in 2016: $4,300
- Net capital gain in 2015: $3,000
- Net capital gain in 2017: $1,000 (even though there was a net operating loss)
Subtracting the net capital gains from the net capital losses, we get:
$13,000 - $4,300 - $3,000 - $1,000 = $4,700
So the amount of Tatoo's capital loss carryover remaining after it applies the carryback is $4,700.
