3. New Year's invoices are included in the current year's expenses, and income tax is not allowed to be deducted before tax. It needs to be added in the final settlement of the current year. Accounting treatment is based on accrual basis. Invoices obtained last year can only be included in last year's expenses, not this year's expenses. If last year's unrecorded invoices were discovered only this year, according to the relevant provisions of the Accounting Standards for Business Enterprises, they can be treated as early errors and accounted for through "previous year's profit and loss adjustment".
