What Byrz is
Byrz is an on-demand modelling tool for Australian residential property investors. We run your property's actual numbers through a tax engine that mirrors the Income Tax Assessment Act 1997 and the proposed 2027 Budget reforms, then produce a single PDF you can read on your own or hand to an accountant.
The tool covers six ownership structures (personal, joint personal, discretionary trust, company, SMSF accumulation, SMSF pension), two sell dates, and the full set of proposed measures: the 1 July 2027 CGT split, the negative-gearing restriction on established residential, the trust minimum tax from 1 July 2028, and Division 296 on super balances above $3M.
What Byrz is not
Byrz is not a financial adviser, accountant, tax agent, credit licensee or investment manager. We do not give personal advice and we do not hold a licence to do so. The reports we generate are scenario modelling under transparent assumptions - the decisions remain yours, or your accountant's if you involve one.
We are also not a substitute for an accountant on complex structures. SMSF, discretionary trust and company ownership all carry compliance load and case-by-case nuance that no calculator can fully capture. The report is built explicitly as a discussion document for that conversation, not a replacement for it.
The methodology, in plain English
Every report runs the same property through the engine TWICE: once under today's rules, once under the proposed reform. The delta is the headline number. Where measures are not yet legislated, they're labelled as such in the report. Where we've had to apply defaults (e.g. trust beneficiary income split, SMSF balance, marginal tax rate), they're flagged with the specific assumption.
We model the federal layer end-to-end (income tax, CGT, negative gearing, depreciation, Div 296). State land tax is included when enabled, but stamp duty, foreign-tax credits, GST, super contribution caps and lender serviceability are explicitly out of scope - that's the line between modelling and advice. See our sources for every ITAA section, ATO ruling and Treasury announcement the engine draws on.
The team
Byrz is built by an engineering team based in Australia working alongside qualified Australian accountants who validate the tax mechanics. We are deliberately a small team; we built Byrz because we couldn't find a tool that would walk us through our own property positions without first signing up a fee-for-service adviser.
