As long as you are an American, you cannot escape two things: 1. You will definitely die. 2. Those who have income must pay taxes. Americans must "summarize" and submit the tax payable for the previous year before April 15th each year. Take all your income from the previous year (which will have vouchers), deduct various tax exemptions, and then calculate how much you should pay based on the appropriate tax rate. Usually, arrangements have been made in the previous year to pay a small amount in advance each time you receive your salary (to avoid having to pay a large amount at once after aggregation). Then after summarizing, the amount that should be paid is subtracted from the amount that has been paid in advance. More refunds and less compensation. Everyone with income must file a tax return. The president is no exception. Of course you can pay an accountant to do it for you. Nowadays, you can file your tax online or fill out a form and mail it to the tax bureau. Every year before 12 o'clock in the evening on April 15, post offices in various places work overtime to accept the long queues of people. Be sure to stamp it before 12 o'clock. That is to meet the deadline. Almost all tax accountants will take a long vacation after April 15th. Because before that day, I was so busy every day that I was dizzy.
