General financial personnel at the management level, such as chief financial officer and financial manager, do not often deal with taxation. They only show their faces in front of tax when they encounter some special circumstances, such as on-site tax inspection or major tax-related interests that need to be negotiated. More people who deal with taxation are the competent accountant and the on-site accountant. As for how often, it depends on your business volume. For example, under normal circumstances, I'm afraid our unit can't handle tax once a year, unless there are some tax problems reported by a certain number of people, or things like changing the taxpayer's qualification from business tax to business tax. However, if the business volume of the unit is large, especially the tax-related business, it may be handled every month.
