How we write

Editorial guidelines

Everything on this site is general information, written in plain words, checked against official sources and dated. When we get something wrong, we fix it and say so.

Sources

• We rely on official and primary sources first: the State Revenue Office, the Valuer-General Victoria, Consumer Affairs Victoria, the ATO, Treasury, the Reserve Bank and legislation.
• Every guide and article lists its sources so you can check them yourself.
• We write in our own words and link to the original.

Dates

• Each page shows the date it was last checked.
• Figures that change, such as rates and averages, are shown with an "as at" date.

Numbers

Where we work out a figure ourselves, we say so, and it can be reproduced from the official rate table linked on the page. Calculator results are estimates, not assessments.

What we do not do

• We do not tell you what to do with your property, your loan or your tax.
• We do not say a valuation is wrong, or promise any saving or outcome.
• We do not predict prices, interest rates or changes to the law.
• We do not accept payment to change what an article says.

Corrections

Tell us at hello@investorsums.com.au. Confirmed errors are corrected promptly and the page's "checked" date is updated.

Languages

Guides and articles are published in English and Chinese. If the two differ, the English version and the official source prevail.
