Business income and tax calculator

How it works

When you run your own business, you need to figure out how much money you need to make to cover everything - your personal income, business expenses, taxes, and still have some profit left over.

What you tell it:

  • How much profit you want your business to keep
  • How much you want to pay yourself personally
  • How much it costs to run your business
  • How much you pay other people to help you

What it calculates:

  • Based on your income, it figures out how much tax you'll owe (income tax, Medicare levy, and potentially a surcharge if you don't have private hospital cover)
  • It adds up everything you need plus taxes to figure out your total gross revenue target

Smart adjustments: Tax is deducted from owner's pay. If your profit is high and tax exceeds owner's pay, then tax is deducted from your profit.

What you get:

  • A clear breakdown showing exactly where all your money goes
  • The total amount you need to earn to meet your goals
  • The ability to see this as monthly or yearly targets
  • Real-time updates as you adjust your goals

switched from hnry to thriday its been night and day difference customer service is much faster and better over all platform is easer to use and has many more features and when i have a complex issue i can get help fast from an accountant i don't normally write 5 star review's ever but I've had a few people go above and beyond to help me on thriday now so felt compelled to do so as that level of service is very rare now days so i would recommend them to other business owners without hesitation
