Changes — tax rules and calculator updates
What changed, when, and why.
Every change to a tax rule or to how YieldAfter calculates is recorded here with its date. Rule values and their sources are listed on the methodology page.
2026-09-30 — Editorial standards, related calculators and advertising
- Added editorial standards and a corrections policy to the About page: primary sources, rule status, versioning, tests before publishing and a public change log.
- Every page links to OwnerCost (the cost of owning your home) and KeptOffer (take-home pay) for its country.
- Removed the site's own ad-consent banner. Ads stay off and can only be switched on together with a Google-certified consent platform.
2026-09-30 — Australia: state stamp duty and land tax
- Stamp duty is now calculated for all eight states and territories from each revenue office's general rates, instead of being typed in.
- Annual land tax is calculated from the land value you enter, on your total holdings in the state, and included as a deductible running cost. NSW uses a three-year average and the ACT a five-year average of land values; WA includes the Perth metropolitan levy.
- New state pages for NSW, Victoria, Queensland, WA, SA, Tasmania, the ACT and the Northern Territory.
- Checked against Revenue NSW's and the Queensland Revenue Office's published worked examples. The ACT duty table is flagged because the latest published rates are for 1 July 2025.
2026-09-30 — Engine v1: year-by-year after-tax model for the UK, US and Australia
- New financial core: monthly mortgage schedules (interest-only and repayment), multi-year projection, after-tax IRR, break-even rent and mortgage rate.
- UK: real income tax bands with property income as the top slice (Finance Act 2026 s.6), 2027/28 property rates of 22%/42%/47% (s.7), Section 24 relief calculated under ITTOIA 2005 s.274AA with carry-forward and the three-way cap, 22% relief from 2027/28, personal allowance taper, High Income Child Benefit Charge, SDLT with the 5% surcharge, and CGT at 18%/24%.
- US: 2026 federal brackets and standard deduction (Rev. Proc. 2025-32), 27.5-year mid-month depreciation, the $25,000 passive loss allowance with suspended losses, NIIT, and depreciation recapture on sale.
- Australia (new): 2026–27 resident rates and Medicare levy, the negative gearing quarantine from 2027–28, the deemed sale on 30 June 2027, CPI indexation and the 30% minimum tax from the Treasury Laws Amendment (Tax Reform No. 1) Act 2026.
- Hold vs sell rebuilt: the previous version compared sale proceeds with rental income without repaying the mortgage or counting the property kept, so it almost always favoured selling. Both paths now end at the same date and repay the loan.
- Cash flow now includes mortgage principal for repayment loans; previously only interest was deducted, which overstated cash-on-cash returns.
- The Section 24 credit is now capped by property profit and adjusted total income as the law requires; previously it was capped by tax, which understated tax when interest exceeded profit.
2026-09-30 — Site housekeeping
- Canonical URLs now end in a slash, matching what the server serves.
- Unknown addresses return a real 404 page.
- US pages no longer show UK terms.
