A consumer painting quote in Melbourne must show a single GST-inclusive total under Australian Consumer Law’s “single price” rule, the price you are quoted has to include GST and every mandatory charge, so a quote that hides GST and tacks it on only at invoice time is non-compliant and a clear red flag. According to the ACCC, when a business displays or quotes a price to a consumer it must state the total price as a single figure.
We’ve been painting Melbourne homes for more than three decades and written thousands of residential quotes. This guide explains exactly how GST works on a painting quote, why some quotes have no GST line at all, how to check a painter’s ABN and insurance for free, and how to compare quotes like-for-like so you’re not caught out by a hidden tax later.
Does a painting quote include GST?
Yes, a quote given to a consumer must show a single total that already includes GST and all compulsory charges.
This is the “single price” rule under Australian Consumer Law. When a business quotes or advertises a price to a household customer, the ACCC requires that price to be the total amount payable, stated as one figure, with GST and any other unavoidable fees already built in. You should never have to do mental arithmetic to work out what you’ll actually pay.
In practice, a compliant residential painting quote will read something like “$6,600 including GST”, one number, all in. It is fine for the quote to also show the GST component separately for transparency (for example, “$6,000 + $600 GST = $6,600”), as long as the prominent figure is the GST-inclusive total. What is not fine is a quote that shows “$6,000” in big print and only mentions “plus GST” in small text, or not at all, then surprises you with a 10% larger invoice.
Key takeaway: A consumer painting quote should always display a single GST-inclusive total. If the headline price excludes GST and the tax appears only on the final invoice, that quote does not meet the single-price rule.
Why do some painting quotes not charge GST?
Because a business only has to register for GST once its turnover reaches $75,000 a year, a painter below that threshold may legally charge no GST.
This trips a lot of homeowners up. GST registration is not automatic for every tradesperson. The ATO states that a business must register for GST once its annual turnover hits $75,000, a threshold that has not changed since GST was introduced in 2000. A sole-trader painter who turns over less than $75,000 a year may choose not to register, and if they aren’t registered they cannot charge GST at all.
That’s the legitimate reason some small operators’ prices look noticeably lower: there’s no 10% GST added because none applies to them. It’s perfectly legal. The thing to understand is that you’re then comparing a GST-free price against a GST-inclusive one, which is not a like-for-like comparison. A $5,000 quote from an unregistered painter and a $5,500 GST-inclusive quote from a registered one are actually much closer in underlying value than the headline numbers suggest.
It also has practical implications. An unregistered painter cannot issue a “tax invoice” and cannot give you a GST component, which can matter if you ever need to claim the work for tax (for example on an investment property). Larger, established painting businesses are almost always over the $75,000 threshold and therefore registered.
Key takeaway: A painter under $75,000 annual turnover may not be registered for GST and may charge none, which is legal but means their lower price isn’t directly comparable to a GST-inclusive quote.
How do I check a painter’s ABN and GST status?
Use the free ABN Lookup tool to confirm the ABN is active and whether the painter is registered for GST.
Every legitimate business operating in Australia should have an Australian Business Number (ABN). You can verify any painter’s ABN and their GST-registration status in under a minute, for free, at ABN Lookup, the public register run by the Australian Business Register. Enter the ABN printed on their quote, or search by business name, and you’ll see:
- Whether the ABN is active (a cancelled ABN is a serious warning sign)
- The entity name and type (sole trader, company, etc.)
- Their GST registration status and the date it took effect
- The business’s location state
If a painter who claims to charge GST does not actually appear as GST-registered on ABN Lookup, something is wrong, they may be charging you a 10% “GST” they’re not entitled to collect. Conversely, if they’re registered and charging GST, that all checks out.
A GST-registered painter also has obligations on the paperwork itself. The tax invoice they give you must show their ABN and either the GST amount or the words “price includes GST”. If a tax invoice arrives with no ABN and no GST statement, ask for a corrected one before you pay.
| What the quote shows | What it means | What to do |
|---|---|---|
| ”$6,600 including GST” | Compliant single-price quote from a GST-registered painter | Proceed; this is the standard you want |
| ”$6,000 + GST” as the headline | GST excluded from the prominent price, breaches the single-price rule | Ask for the GST-inclusive total in writing before comparing |
| No GST line, lower total | Painter likely under $75k turnover and not GST-registered | Legal, but compare against other quotes’ GST-inclusive figures |
| Charges “GST” but not listed on ABN Lookup | Collecting GST they may not be registered for | Query it; verify the ABN before signing |
| No ABN on the quote at all | Not operating as a registered business | Treat as a red flag; request the ABN and verify it |
What insurance should the quote confirm?
The quote should confirm current public liability insurance, and you should ask for a certificate of currency before work starts.
Separate from tax, you want proof the painter is insured. Public liability insurance covers you and third parties if the painter damages your property or injures someone while working on your home, for example, paint damage to flooring, a fall, or harm to a neighbour’s property. Before any work begins, ask the painter for a current certificate of currency for their public liability policy. This single document confirms the cover is active and shows the insured amount.
Consumer Affairs Victoria advises Victorian homeowners to confirm a tradesperson’s details and insurance when getting quotes, rather than taking verbal assurances at face value. A professional painter will hand over a certificate without hesitation. Modernize Solutions carries $20 million in public liability cover and can provide a certificate of currency on request.
Key takeaway: Always ask for a current certificate of currency for public liability insurance before work starts, a verbal “yes, we’re insured” is not proof.
How should I compare quotes fairly?
Compare every quote on a GST-inclusive basis so you’re measuring like-for-like, then confirm ABN, GST status and insurance before signing.
The single biggest mistake Melbourne homeowners make is comparing a GST-exclusive number against a GST-inclusive one and thinking the first painter is cheaper. To compare fairly:
- Get every price as a GST-inclusive total. If one quote excludes GST, ask the painter to restate it inclusive, or simply add 10% yourself before comparing.
- Note who is and isn’t GST-registered. An unregistered painter’s price has no GST to add, factor that in rather than assuming they “forgot” it.
- Verify each ABN on ABN Lookup so you know you’re dealing with a registered business.
- Confirm insurance with a certificate of currency for each painter you’re seriously considering.
Only once all the numbers are on the same GST-inclusive footing can you judge which quote is genuinely better value, and value is about scope, preparation and warranty, not just the headline figure. What a GST-inclusive total should land near depends on the size of the job. Our Melbourne house painting cost guide sets out the price factors and typical ranges.
Is a quote that adds GST later a red flag?
Yes, quoting a price low and adding GST only on the invoice breaches the single-price rule and inflates your final bill by 10%.
If a painter quotes you “$5,000” and then issues an invoice for $5,500 “plus GST,” you’ve effectively been quoted a price that was never the real total. Under the ACCC single-price rule, the price quoted to you as a consumer should already have included that GST. This isn’t a paperwork technicality, it’s a 10% difference on a four- or five-figure job. Always insist the written quote states the GST-inclusive total up front, so there are no surprises when the invoice lands.
Key takeaway: Getting a quote in writing with the GST-inclusive total clearly stated protects you from a 10% “surprise” at invoice time.
“A painting quote should be one honest number, GST included, if you have to do maths to find out what you’ll really pay, the quote isn’t being straight with you.”, Modernize Solutions, painting Melbourne homes since 1987
“We put GST-registration and a $20 million insurance certificate on the table because a homeowner deserves to verify exactly who they’re hiring before brush touches wall.”, Modernize Solutions, painting Melbourne homes since 1987
What if the painter has no ABN at all?
A painter operating without any ABN is not running a registered business, treat it as a serious red flag.
A missing ABN means there’s no easy way to verify who you’re dealing with, the business may not be properly established, and you’ll have little recourse if something goes wrong. Every professional Melbourne painter should be able to give you an ABN that appears as active on ABN Lookup. If they can’t or won’t, walk away and find a painter who operates transparently.

Frequently asked questions
Should a painting quote include GST?
Yes. Under Australian Consumer Law’s single-price rule, a price quoted to a consumer must be a single total that already includes GST and all mandatory charges. A Melbourne painting quote should therefore show a GST-inclusive total. A quote that hides GST and adds it only at invoice time is non-compliant and a red flag.
Why do some painting quotes not charge GST at all?
A business only has to register for and charge GST once its turnover reaches $75,000 a year. A painter under that threshold may not be registered and may legally charge no GST, which is why some small operators’ prices look lower. There is simply no GST line because none applies.
How do I check a Melbourne painter’s ABN and GST status?
Use the free ABN Lookup tool from the Australian Business Register. Enter the painter’s ABN or business name to confirm the ABN is active and whether they are registered for GST. A GST-registered painter’s tax invoice must also show their ABN and either the GST amount or the words “price includes GST”.
What insurance should a painting quote confirm?
Ask for a current certificate of currency for public liability insurance before any work starts. This protects you and third parties if property is damaged or someone is injured. Modernize Solutions carries $20 million in public liability cover and can supply a certificate on request.
