Cash flow is the lifeblood of an SMSF property investment. After the 2026 residential borrowing ban, SMSF trustees buying residential property with cash need positive cash flow even more urgently — there is no leverage to amplify returns, so the property must earn its keep from day one. This guide explains how to calculate your SMSF property cash flow and what the numbers mean for your fund’s health.
How to Calculate SMSF Property Cash Flow
SMSF property cash flow is the annual rental income minus all annual property costs, including property management fees, council rates, water rates, insurance, maintenance and repairs, body corporate levies (if applicable), and any loan repayments if using an LRBA for commercial property.

Frequently Asked Questions
What happens if my SMSF property is cash flow negative?
If your SMSF property is cash flow negative, the fund must cover the shortfall from member contributions or other income. This is legal but must be planned for carefully — the ATO expects SMSF trustees to demonstrate that the fund can meet all liabilities as they fall due. Persistent negative cash flow in an SMSF is a compliance risk.
Does the SMSF tax rate affect cash flow calculations?
Yes. SMSFs in the accumulation phase pay 15% tax on rental income, which is significantly lower than personal income tax rates. In pension phase, rental income is tax-free. This tax advantage improves SMSF property cash flow compared to personally held investment properties.
Should I sell my SMSF residential property if it is cash flow negative after the ban?
This depends on the capital growth outlook, your fund’s overall cash position, and how long until members retire. Many SMSF specialists are recommending a strategic review of residential holdings in light of the ban — particularly for properties with low yields and high holding costs. Speak to an SMSF-accredited financial adviser before making this decision.
