Question 1

Is plumber labor taxable in New South Wales?

Accepted Answer

In New South Wales, labor performed by plumbers is generally subject to GST under ATO: GST and the Building and Construction Industry (NAT 3753). You must calculate the statutory 10% tax on both materials and service labor unless an explicit capital improvement exemption applies.

Question 2

What GST rate should a plumber charge on parts and materials in New South Wales?

Accepted Answer

The statutory base combined GST rate in New South Wales is 10%. When billing clients for fixtures, piping, valves, water heaters, and drain assemblies, apply 10% to the materials subtotal. DoxMitra automatically separates taxable materials from tax-exempt labor to ensure you never over-collect or under-collect taxes.

Question 3

What mandatory fields must be on a plumber invoice in New South Wales?

Accepted Answer

To be fully audit-compliant with the Australian Taxation Office (ATO), your invoice must include: (1) Licensed contractor business name, physical address, and contact details; (2) State license number (NSW Fair Trading — Contractor Licence) or tax ID; (3) Client name and job location; (4) Itemized breakdown separating physical parts from labor; (5) Calculated New South Wales GST; (6) Sequential document number; and (7) Payment terms or receipt confirmation.

Question 4

How long must a plumber keep invoices and receipts in New South Wales?

Question 5

What is the legal difference between a plumber estimate, invoice, and receipt in New South Wales?

Accepted Answer

An **Estimate** is a non-binding quotation or scope proposal outlining anticipated labor and materials for backflow prevention, gas line extensions, and main sewer connections. An **Invoice** is a formal, legally enforceable request for payment once milestones are reached or work is completed. A **Receipt** is proof of payment showing a zero balance due. DoxMitra lets you switch between all three with a single click while preserving line items.

Question 6

How do I handle tax-exempt clients or commercial subcontracts in New South Wales?

Accepted Answer

If you are subcontracting for a general contractor or working for a tax-exempt entity (schools, government, nonprofits) in New South Wales, obtain a signed copy of NAT 2954 (BAS lodgement). In DoxMitra, you can set the tax rate to 0.00% and record the exemption certificate number in the notes section to maintain a clean audit trail.
