Hi everyone,
I’m trying to understand how the Labour Party’s proposed 28% Capital Gains Tax (slated for July 2027 if they win) would actually work for a normal "home and income" situation. I’ve been reading through the policy details, but tax rules for mixed-use properties get confusing quickly, so I’d love to know if I'm understanding this right.
To keep the math simple, I’ll use some round, hypothetical numbers to explain my plan:
Context: Let’s say I bought a property right at the COVID peak for $1,200,000, but with a 30% market drop, it's currently valued lower (around $840,000).
Extention Plan: For simplicity purpose, let's assume I do a home extension down the track (costing say, $300,000) to build a small flat attached to the house. It will likely be finished after the July 2027 rollout date.
- The new flat will take up about 25% of the total property area. It won't have separate council utility meters, and the plan is just to get long-term flatmates or boarders to help cover expenses. We live in the other 75% as their main home.
- We also want to save up for solar panels and a battery setup (say, $25,000) to keep power bills down for everyone.
From what I can gather, here is how the CGT would handle this if they ever sold the property years from now:
The Peak-COVID Rule: Because the original purchase price ($1.2M) was higher than the July 2027 market value ($840k), the tax baseline automatically locks in at the higher $1,200,000 mark so the owner isn't penalized for buying at the absolute peak.
Adding Renovations: Even though the extension and solar happen after 2027, the cash spent on them ($300k + $25k) counts as capital improvements. This gets added to the baseline, pushing the total tax-free threshold to $1,525,000.
The Pro-Rata Split: The 75% main home part stays completely tax-free. The 28% CGT only applies to the 25% rental portion of the profit made above that $1,525,000 milestone. So if the house eventually sells for $1,700,000, the overall difference above the baseline is $175,000. The tax would only apply to 25% of that difference ($43,750), making the final tax bill around $12,250.
Day-to-Day Taxes: Because we are doing long-term flatmates with a single meter, can just claim 25% of the shared power/rates bills against the rent?
Does this logic sound right to those who have been following the policy closely? Am I missing any hidden traps or missing details about how pro-rata splits work when a renovation happens after the tax comes into effect?
We may rent the space on and off basis. May be one year we may give space on rent but next year we may not. How would it work?
Really appreciate any guidance or corrections if I've misread the policy!
