The minimum filing standard for fraud is 3000 yuan. However, due to the different levels of economic development in different places, the criteria for filing a case are not necessarily the same, which needs to be decided in combination with the local economic development level.

According to the Interpretation on Several Issues Concerning the Specific Application of Laws in Handling Criminal Cases of Fraud, those who swindle public or private property from 3,000 yuan to 654.38 million yuan, from 30,000 yuan to 654.38 million yuan and from 5 million yuan are deemed as "large amount", "huge amount" and "huge amount" respectively.

For the sentencing of fraud, China's criminal law also has relevant provisions: defrauding public and private property, with a large amount, shall be sentenced to fixed-term imprisonment of not more than three years, criminal detention or control, and fined; If the amount is huge or there are other serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than three years but not more than ten years and shall also be fined; If the amount is especially huge or there are other especially serious circumstances, he shall be sentenced to fixed-term imprisonment of not less than 10 years or life imprisonment, and shall also be fined or confiscated.
