Business Structure for Tax Purposes: What to Consider

When you look solely at business structure for tax purposes, it might be tempting to think that you have an easy decision to make when it comes to deciding the best business structure to use at tax time. It is more complex than mere tax rates. This is what to consider:

  • Liability Exposure: Sole traders are exposed to all legal risks, but companies act as a form of protection.
