If you own a rental property or run a business, you’ve probably asked this at some point:
“Is this a repair I can claim… or something I have to capitalise?”
It’s one of the most common (and confusing) tax questions we get.
Inland Revenue has just released updated guidance (IS 26/01), and while the full document is detailed, the core principles are actually quite straightforward once you break them down.
Let’s walk through what you need to know.
The Simple Starting Point
To claim a deduction, the cost must:
- Relate to earning income, and
- Not be considered capital expenditure
That second point is where things get tricky.
Repairs and maintenance = usually deductible now
Improvements or upgrades = usually capital (not immediately deductible)
So… What’s the Difference?
At a high level:
Repairs = fixing wear and tear, keeping something in working order
Maintenance = ongoing upkeep
Capital/Improvements = making something better, newer, or different
But in practice, it’s not always obvious.
The Two-Step Test
IRD and the courts use a two-step approach:
Step 1: What exactly is the asset?
Before you even look at the work, you need to ask:
What is the thing being worked on?
Is it:
- The whole building?
- A roof?
- A heat pump?
- A separate chattel (like an appliance)?
This matters because:
- Replacing part of something might be a repair
- Replacing the whole thing is more likely capital
Step 2: What was actually done?
Now look at the work itself, and ask:
Did it just fix wear and tear? Or did it replace, upgrade, or significantly improve the asset?
Key triggers that push something into capital:
- Replacing or reconstructing most (or all) of an asset
- Changing how it works or extending its life significantly
- Upgrading it beyond its original condition
A Practical Guide
Here’s a simple way to think about it:
Situation: Fixing a leak, patching damage, repainting
Likely Treatment: Yes - Deductible (repair)
Situation: Replacing part of something worn out
Likely Treatment: Yes - Usually deductible
Situation: Replacing the entire asset (e.g. full roof, full kitchen)
Likely Treatment: No - Capital
Situation: Upgrading to a better or more modern version
Likely Treatment: No - Capital
Situation: Work that’s part of a bigger renovation project
Likely Treatment: No - Capital
A Few Important Watch-Outs
1. Buying a Property That Needs Work
If you buy a property and then fix it up straight away:
That work is often not deductible
Why? Because it’s considered part of getting the asset ready for use, not repairing something you’ve used to earn income.
This is covered in QB 25/17 (Essential Initial Repairs) and catches a lot of property investors out.
2. “It’s Just Repairs” (But Actually It’s a Project)
If multiple jobs are done together as part of a bigger plan:
The whole lot can be treated as capital
Even if some parts look like repairs on their own.
3. Healthy Homes Work
Costs to meet Healthy Homes standards can fall on either side:
- Some items = repairs (deductible)
- Others = improvements (capital)
This is covered in QB 20/01, and it depends on the nature of the work.
4. Fixing Defects (Like Leaky Buildings)
Even if you're fixing a problem:
If the work is extensive and changes the building significantly, it’s likely capital
The cause doesn’t matter - it’s the scale and nature of the work that counts.
If It’s Capital… Is It Lost?
Not necessarily. Capital costs may:
- Be added to the asset’s value, and
- Be claimed over time through depreciation (if applicable)
There may also be newer rules (like Investment Boost) that apply depending on timing and asset type.
The Key Takeaway
There’s no single rule that covers every situation. But in most cases, it comes down to this:
Are you fixing something… or improving it?
And just as importantly:
How big is the work, and what exactly are you working on?
How we can help
This is an area where small details make a big difference and getting it wrong can mean either:
- Missing out on deductions, or
- Claiming something you shouldn’t
