How to calculate your 2021 Tax Refund

Tax time is arguably one of the most exciting times of the year for most Australians. 

I mean, who isn’t excited about finding out how much tax they will get back? (or.. How much you might have to pay back), which doesn’t seem as exciting.

But there’s really only one way to find out. And who knows, there might be some extra working from home deductions, among others deductions without receipts, you can claim. 

Using the in-built tax refund calculator inside One Click Life’s Tax Return app is the quickest and easiest way to accurately calculate and get your tax refund estimate. It’s so easy you could do it from your couch in minutes.
