First question: 1. The new tax law can fully deduct the actual salary. 2. The deduction limit of trade union funds is 2% of wages, welfare funds are 14%, and staff education funds are 2.5%. The above three items can be deducted by 80 * (2%+ 14%+2.5%) = 65438+. The taxable income of the company in that year was 800+10-15 = 7.95 million yuan.

The second question: the taxable income in that year was 6000-2000-450-1000+10+5 = 25.65 million yuan; Make up for the loss of 2565-160-140 = 22.65 million yuan in the previous five years.

Payable enterprise income tax is 2265 * 25% = 5,662,500 yuan.

The third question: the title does not indicate the year, and the personal income tax on wages and salaries cannot be calculated. Because 20 1 1 is the threshold of 2000 before September, and then it is 3500.

The fourth question is the same as the third. .
