However, according to the accounting accrual basis and the principle of timeliness, the current expenses should be charged in the current period, and in case of other special circumstances, they should also be reimbursed and charged in time.

In actual work, it is impossible to reimburse and collect all invoices and expenses in the current month. VAT invoices still have a deduction period of 180 days. Explain that the law also allows us to deal with it according to the actual situation of our work. But being a man, you can't go too far. Therefore, taxation now generally requires that in case of New Year's Eve, the documents and expenses of the fourth quarter of last year can be reimbursed in the first quarter of next year. In other words, the reimbursement and accounting period of expense invoices are generally controlled within 180. This is just an unwritten habit, so it is for reference only.
