Do you need any license or permits to open your own factory?

Answer:yes

Explanation:

The most common license and permit requirements for manufacturing businesses include:

a basic business operation license from the city or county where your business will operate

a federal employer identification number (EIN) - - also called a tax identification number - - from the IRS, and a similar tax ID number from your state's department of taxation or revenue

a fictitious business name or "doing business as" (dba) permit, if you will operate under a name that is different from your legal entity's registered name

zoning and land use permits that cover your manufacturing business's operations

sales tax license to sell your manufactured goods

health department permits if your manufacturing business includes the preparation or sale of food

building permits.

However, licenses and permits are mandatory, and before you can legally begin to operate your business, you need to have all its licenses and permits in place. Additionally, if your business has employees or sells taxable goods or services, you need to register with the taxing authorities.
