However, the input tax deduction has no time limit, that is to say, if an input credit is formed, it can be retained indefinitely until the deduction is completed.
When the general taxpayer in the pilot project of "VAT reform" concurrently engages in VAT-exempt items (or simple taxation items and non-VAT taxable services), and 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 input tax amount that cannot be divided 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 usually paid monthly, and "current period" is "current month". The monthly operating conditions of enterprises are different, and the proportion data are different. From this perspective, the proportional calculation method is not perfect. It is precisely because of this that enterprises are left with the blank of VAT planning.
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 an important basis for law enforcement inspection by audit institutions and tax authorities. The receipt is the proof of receipt and payment, and the 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 include the payment from the buyer to the seller according to the agreed conditions, and must include the date and quantity, which is an important proof of accounting. China's accounting system stipulates that valid invoices for purchasing products or services are called tax invoices. The vouchers of government departments' fees and levies have different names in different periods and different fees and levies, but most of them are collectively referred to as administrative fees and receipts. For internal audit and verification, each invoice must have a unique journal number to prevent the invoice from repeating or skipping.
Simply put, the 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.
