Tax Deductions for Builders: The 2026 Guide

Building is a high-overhead business. Between tools, vehicles, and insurance, your expenses stack up fast. The good news is that most of these are deductible.

1. Equipment & Tools

From cement mixers to cordless drills. If it's used to generate income, it's deductible.
Tip: Don't forget small items like drill bits, saw blades, and sandpaper. These "consumables" are 100% deductible immediately.

2. Sun Protection

If you work outdoors (which you do), the ATO allows you to claim:

• Sunglasses (must be UV rated).
• Sunscreen (Zink/SPF 50+).
• Hats and caps (even better if they have your logo).

3. Electronics & Home Office

Do you do your quotes and invoices at night? You can claim a portion of your laptop, iPad, phone bills, and even home internet usage based on the percentage of business use.
