The owner of the sole proprietorship in Singapore has unlimited business liability because it doesn’t have a separate entity. This implies that creditors can sue the owners for debts and can claim against your assets, like your personal property.
However, when you setup a private company, creditors can’t do that. In other words, your liability is limited to the sum of investment you’ve made in the entity while it keeps your personal assets protected from court orders.
By looking at this table, you can see that the effective tax rate for limited liability companies/private limited is imposed when their taxable income reaches 300,000 Singaporean dollars while taxable income for sole proprietorships is 100,000 Singaporean Dollars. Furthermore, for the first 3 years of the company setup and incorporation, there is zero tax on the first 100,000 Singaporean Dollars of profits every year. Also, once the income is taxed, then the LLC can distribute dividends to the shareholders, and that too, tax free.
