On the issue of taxation, both individual industrial and commercial households and partnership enterprises are levied according to individual income tax, and there is no tax preference.

You can sign a partnership agreement with Wang. This behavior is legally understood as:

1. Wang is an individual industrial and commercial household;

2. Your family invested in this individual industrial and commercial household and agreed to change the nature of the enterprise into a partnership enterprise.

In the partnership agreement, the above two points must be made clear to avoid potential legal risks.

Supplementary answer:

Divided into two questions:

1. Financial problems

No matter how big the initial investment is and how different the dividends are, we should always negotiate our respective shares before signing the partnership agreement. Before a partnership enterprise is registered, all financial problems before its establishment should be properly handled. The articles of association of a partnership enterprise shall define and standardize the rights and responsibilities from the date of its establishment.

2. Dispute settlement

If no agreement can be reached on the above financial issues, a lawsuit can be filed to confirm the rights and interests of family members with the judgment of the court.

The risk is that because Wang is registered as an individual industrial and commercial household, the court will decide that Wang has debts to your family, not that your family has invested in Wang. The difference is that if you are in debt, Wang Can will repay the principal plus interest. If you invest, your family has the corresponding investment rights, including voting rights and dividend rights.
