Yes, at least it's not accurate. It's just a rough idea. It's even better to report more taxes, and it's very troublesome to find out less taxes. The tax authorities will think that you have evaded taxes, not only will you be urged to pay, but you will also be fined in serious cases.

How to correct it?

Keep accounts according to the regulations, make a profit statement every month (if accounting statements are not needed), and file tax returns according to the profit statement. If the business is relatively simple, you can set fewer subjects to reflect the financial situation of the enterprise. In this way, your records are basically consistent with the actual situation and will not cause tax trouble. Once checked, it can also provide information.
