tax on horse racing profits

{Amount of temporary income (profit) - expenses - special deduction (500,000 yen)} x 1/2 = taxable income amount of temporary income

If you apply this tax calculation method to the actual race,
As an example, in the race on February 23, 2020,

（28,000,000-10,000,000-500,000）×1/2＝8,750,000

Since this is the amount of tax withheld from profits,

28,000,000－8,750,000＝19,250,000

This is the calculation.

Instant Johnson, a comedy trio, said, ``It was decided that the lost betting ticket would not be an expense. It's like the whole thing is taken away," he said of his own experience.

In other words, you actually spent 100,000,000 yen in a horse race and missed out, but suddenly made a profit of 150,000,000 yen in one race.

However, the tax office didn't calculate the betting ticket 100,000,000 as an expense, so it was taxed excessively.

150,000,000×0.45＝67,500,000

Actual profit is 150,000,000-100,000,000 (expenses) -67,500,000 (income tax)

＝-17,500,000

As a result, it turned into a deficit.
