A business or organizational structure is the type of entity you want to own and that determines how it should be run with regards to legalities, amount of tax you pay, responsibilities, procedures, & asset protection. There are four main business structures namely sole trader, partnership, company, and Trusts. The structure of your business can affect certain areas such as legal compliance, tax to pay and entitlements to discount on capital gains tax. Your ideal business structure is determined by your individual income/wage levels, business profit levels, assets you own, risk of being sued, and family members/beneficiaries income levels.
