There is no time limit for the input tax deduction, that is to say, if the input tax deduction is formed, it can be retained indefinitely until the deduction is completed.
In the "VAT reform" pilot, general taxpayers run VAT exemption items (or simple taxation items and non-VAT taxable services). When the input tax cannot be accurately divided, it is necessary to calculate the non-deductible input tax.
The calculation formula is:
Non-deductible input tax amount = total non-deductible input tax amount in the current period × (sales of taxable items in the current simple taxation method+sales of non-VAT taxable services+sales of VAT-exempt items) ÷ (total sales in the current period+total turnover in the current period).
Value-added tax is generally paid monthly, and "current period" is "current month". The monthly operating conditions of enterprises are different, and the proportion data are also different. From this point of view, the proportional calculation method is not perfect. It is precisely because of this that a blank of VAT planning is left for enterprises.
Extended data:
Invoice refers to the business vouchers issued and collected by all units and individuals in buying and selling goods, providing or receiving services and engaging in other business activities. It is the original basis of accounting, and it is also an important basis for law enforcement inspection by audit institutions and tax authorities. Receipt is the proof of receipt and payment, and invoice can only prove that the business has happened, but can't prove whether the money has been received or paid.
Invoice refers to the text issued by the seller to the buyer in economic activities, including the name, quality and agreed price of the products or services provided to the buyer. In addition to the advance payment, the invoice must also include the money paid by the buyer to the seller according to the agreed conditions, and must include the date and quantity, which is an important proof of accounting. According to China's accounting system, valid invoices for purchasing products or services are called tax invoices. The charging vouchers of government departments have different names in different periods and different charging items, but most of them are collectively referred to as administrative fee receipts. For internal audit and verification, each invoice must have a unique journal number to prevent duplicate or skip invoices.
Simply put, an invoice is the original proof of the cost, expense or income incurred. For the company, the invoice is mainly the basis for the company to make accounts, and it is also the expense certificate for paying taxes; For employees, invoices are mainly used for reimbursement.
