Embed the AU Negative Gearing Grandfathering Checker

Paste this into any HTML block on your site. The widget will render automatically, mobile-responsive, no setup.

<iframe
  src="https://nestpath.com.au/embed/grandfathering-checker?utm_source=embed&utm_medium=widget"
  width="100%"
  height="900"

  title="AU Negative Gearing Grandfathering Status Checker — by NestPath"
  style="border:0;max-width:740px;display:block;margin:0 auto;"
></iframe>

Default height 900px covers the widget + most filled-in result states. For very tall result outputs (SMSF, special entity) the iframe scrolls internally.

WordPress (with iframe shortcode plugin)

Squarespace, Wix, Webflow, Ghost, Shopify, Notion:use the default iframe HTML above inside an "Embed" or "HTML" block.

Substack: iframes are restricted — instead link to the source guide with the checker embedded.

• 3 questions, 30 seconds — contract date + property type + buyer entity
• Definitive status: grandfathered / new-build carve-out / established ring-fenced / special-entity
• Plain-English rules + action items + source citation (Budget Paper No. 2 page reference)
• Special-case handling: SMSF, discretionary trust, partnership, vacant land
• No PII collected. Pure client-side logic. Mobile-responsive.

The widget is licensed CC BY 4.0. You can embed it on commercial AND non-commercial sites for free. The only requirement is that the "Built by NestPath" attribution at the bottom of the widget remains visible — please don't modify the iframe contents or strip the attribution.

Disclaimer to include on your site:"This tool provides general educational information only and is not personal tax advice. Confirm your position with a registered tax agent before contract exchange."

Does it cost anything?

No. Free for commercial and non-commercial use under CC BY 4.0.

Do I need an API key?

No. The widget is pure client-side React — no backend calls, no rate limits, no key registration.

Will the widget update if AU FHB policy changes?

Yes — automatically. The iframe loads the current widget from NestPath, so any update we make to the logic or copy flows through to every embedded instance immediately.

What if I want a customised version?

For colour/branding variants reach out via the NestPath contact page. We can add per-embed UTM tracking for partner sites.

Is the data accurate?

Yes — logic is built from the 12 May 2026 federal budget (Budget Paper No. 2) plus ATO ruling SMSFR 2012/1 and section 26-102 ITAA 1997 for vacant-land treatment. Sources cited per output state.
