Before you pay a deposit: what the law in your state allows
The deposit a tradesperson can ask for is capped by law, and the cap changes by state and job size. So do the licence, written contract and insurance rules. Check what applies at your job value, with every rule cited to the act and your state regulator, verified on 2026-07-17.
What applies at your job value
Pick your state and a rough job value. The requirements that apply at that value appear below, with the official source behind each one. Your final signed contract price decides, not the estimate.
Choose a state and a value to see the requirements that apply at that size of job.
Whatever the value, check the licence first
Every state runs a free official register. It is the single strongest check before any money moves:
- New South Wales: Check a NSW licence (Service NSW) (opens in new tab)
- Victoria: Check a registered building practitioner (Building and Plumbing Commission) (opens in new tab)
- Queensland: Check the QBCC licensee register (opens in new tab)
Then see the public evidence we hold: check a business by name or browse the registers we track.
Common questions
How much deposit can a tradie ask for?
It depends on your state and the contract value. In NSW, residential building-work deposits are capped at 10 percent. In Victoria it is 10 percent under $20,000 and 5 percent at $20,000 or more. In Queensland it steps from 20 percent (small jobs up to $3,300) to 10 percent, then 5 percent at $20,000 or more. The cap binds on the final signed contract price.
Is a 30 percent deposit legal?
For residential building work in NSW, Victoria and Queensland, a 30 percent deposit is above the legal cap. Queensland's off-site work rule can allow up to 20 percent when more than half the contract value is genuine off-site work such as prefabrication. Check the rule for your state and talk to the regulator before paying.
When does a tradesperson need a licence?
Each state sets its own threshold: general building work over $5,000 in NSW, over $10,000 in Victoria (a registered building practitioner), and over $3,300 in Queensland. Electrical, plumbing and gas work needs a licence at any value everywhere. The licence checks are free and official.
What happens if I pay more than the legal cap?
The caps exist because a large deposit is the most common way homeowners lose money to bad operators. If an ask is above the cap, that is a fact worth raising with the tradesperson and, if needed, your state regulator. This page cannot tell you what to do in your specific situation; the regulator can.
This is guidance from the public rules, not legal advice. The thresholds bind on your final signed contract price, not an estimate, and state law changes. Check the regulator's current page before you sign or pay anything.
