You don't have to go to the inland revenue department to copy the tax. After copying it to your computer, you can use it to file tax returns. However, when copying taxes, we must be careful not to copy them at the end of the month. For example, if you declare your taxes on April 10, you cannot copy them on March 3 1 0. You should make copies of them before filing your tax returns in April. If the above situation occurs, you can take the ic card and ask the tax bureau to adjust it for you, and then copy it again on the computer.
