Navigating First-Home New-House Concessions & Substantial Renovations: What Homebuyers Need to Know

Buying a home is one of the biggest decisions many people make, and in Australia (or other places with similar rules), there are often tax or duty concessions available for first-home buyers. But what happens when you buy an existing house which was recently renovated heavily—can that home ever qualify as a “new” home for concession purposes? The answer isn’t simple, and understanding substantial renovations is key.

What are the main concessions / reliefs?

First-Home Concession

This typically applies to any first home you buy (whether new or existing), provided you meet criteria like never having owned a residence before, using the home as your primary place of residence within a certain period, and staying under price/value thresholds.

First-Home (New Home) Concession

This is specifically for homes that are new residential premises, or homes that have been substantially renovated by the seller, making them “new” in the eyes of the relevant law. Because of this, the rules are stricter, and whether a renovation qualifies as “substantial” can change whether you pay full duty/GST or get a concession.

So what counts as “substantial renovation”?

Here are the main principles, based on legal rulings & guidance:

1. Renovations must affect the building as a whole
   It’s not enough to renovate just one room or part of the house. To be considered “substantial”, most of the house should have been renovated. If only a kitchen or a bathroom is redone, but much of the rest is unchanged, that likely won’t be enough.

2. Removal or replacement of all, or substantially all, of the building
   This doesn’t mean you absolutely have to demolish the foundation or remove the roof or external walls—but the renovation must be so extensive that many parts of the building (structural or non-structural) are removed or replaced. This might include:

   • Replacing many non-structural components, such as plumbing, wiring, fixtures, fittings, bathrooms and kitchens throughout most rooms.

   • Possibly some structural work (though not always required), like altering walls (if that affects many rooms), doors/windows involving external walls, flooring, etc.

3. What doesn’t count (or usually doesn’t)

   • Cosmetic renovations alone (painting, changing carpet, light fixtures, minor repairs).

   • Only one area being redone (e.g. just the kitchen and bathroom) with very little else touched.

   • Renovations done after you buy generally don’t change the status of the home at the time of purchase for the purpose of a new-home concession (since what matters is what the seller did, not what you do later).

Why this matters

If a home is considered “new residential premises” (including after substantial renovations by the seller), the sale may be subject to GST / additional duties, or you might be eligible for special first-home/new-home duty/concession relief. Misunderstanding can lead to unexpected additional costs. Conversely, if it doesn’t qualify, you might still get a first-home concession but not the “new home” one.

Practical tips for homebuyers

Ask the seller for documentation

Vendor statements, invoices, declarations that specify whether the property has been substantially renovated, whether the sale is a taxable supply, etc.

Inspect well:

Look at how many rooms are renovated, whether things like wiring/plumbing are replaced, doors/windows, internal walls, etc. The more rooms/parts touched, the more likely the renovation is “substantial”.

Get legal/tax advice before contract signing

It’s best to clarify whether the property will qualify for the new-home concession (or attract GST) rather than be surprised later.

Bottom line

Buying an old house and renovating it yourself after purchase usually doesn’t make it qualify as “new” for first-home new-house concessions.

Only when the renovation has been done by the seller, and it is truly substantial (affecting almost all of the building), might it be treated as a “new residential premises.”

If not, you’ll likely only qualify for the “first home concession” for existing homes, which has its own benefits, but not the same as a new-home concession.

If you’re considering a purchase and wondering whether the property might qualify under “substantial renovations,” feel free to reach out. It’s one of those areas where the details make all the difference.
