Is it okay for small-scale taxpayers of property companies to keep accounts with white stripes?

1, IOUs cannot be deducted before tax, which is beyond doubt, and it will also involve the possibility of tax evasion by the other party, and the tax bureau will trace it;

2. In addition to considering tax risks, the financial system requires that white bars are not allowed to offset accounts. Without a formal invoice, it is impossible to confirm the authenticity and legality of the relevant expenses, so it is not allowed from the financial point of view.
