Corporate Tax Rates: Recent Changes Give Certainty

There are two categories of companies when it comes to the corporate tax rate. The two categories are determined by turnover and business activity.

The rate of 27.5% applies to corporate tax entities known as “base rate entities”. What is a base rate entity? Put simply, it is a company which carries on a business and has an aggregated turnover of less than $50 million. This is up from $25 million in the last financial year (ie 2017-18), but will stay at $50 million until 2023-24. The ALP has confirmed that it will not change the rules for base rate entities if elected – so there we have our first certainty.  


The rate for base rate entities is locked in at 27.5% until 2023-24. The tax rate for all other companies remains at 30%, ie the standard corporate tax rate. This will not change.


There had been legislation before Parliament that proposed to progressively extend the 27.5% corporate tax rate to all companies regardless of turnover. However, the legislation did not make it through the Senate and the Government has since announced that it would not proceed with this proposal. This provides us with our second certainty – there will be no changes to the standard corporate tax rate.

The tax rate for base rate entities is scheduled to reduce after 2023-24, as this has already been legislated. It is reasonable to state this as the third certainty – that the tax rate for base rate entities will decline progressively to 25% by 2026-27.

Now, this is all perfectly straightforward if your company is carrying on what may be termed a trading business, eg providing services, buying and selling trading stock, importing/exporting etc. But if the activities of the company wholly or partly consist of receiving returns on investments – such as rent, interest and dividends (which are termed “passive income”) – then it can get a bit tricky.

The Government never intended that companies receiving passive income should benefit from the lower tax rate. It recently changed the rules for base rate entities to ensure this does not happen.

A base rate entity will only qualify for the lower 27.5% rate for a particular year if its passive income is less than 80% of its assessable income (and of course its aggregated turnover is less than $50m). Put the other way, companies that receive more than 80% of their income in passive forms will pay tax at the standard corporate tax rate, regardless of turnover.

The passive income is termed “base rate entity passive income” in the amending legislation. And what qualifies? Well, dividends and the associated franking credits to start with. Interest (or a payment in the nature of interest) also qualifies – but not if the entity is a financier – as well as royalties and rent. Another key area that qualifies as base rate entity passive income is net capital gains. This could be important for smaller companies – in that the sale of a substantial asset could shake the income mix and possibly put access to the lower rate at risk.

Does your company derive investment income?

If you are not sure of the implications of the new company tax rates, we can help. For example, if your business operates via a company, it may be worthwhile using the CGT rollover provisions to transfer assets into a separate entity, to ensure that the 80% rule is not breached. The split 27.5% / 30% rate also has implications for the imputation system and franking credits, which we would be happy to discuss.  Contact one of our accountants in North Sydney, Crows Nest or Chatswood for any assistance.
