Tips for it contractors
- ·State the billing period and rate clearly (e.g. '10 days @ $720, 1–14 June'). Agencies and finance teams reconcile against timesheets.
- ·If your client deducts schedular/withholding tax (IR330C), show it as a deduction line and note the rate. Your IR3 needs to reconcile to it.
- ·Most IT contractors clear the $60,000 GST threshold quickly. Register, show the 15% line, and remember GST sits on top of the gross before any withholding.
IT Contractor invoicing, answered.
How does withholding tax appear on a contractor invoice?
If your client deducts schedular payments under an IR330C, show your gross fee, then GST at 15% if registered, then a withholding tax deduction line at your nominated rate. The 'amount payable' is what lands in your account; the withheld amount is credited to your IRD account.
Do I charge GST and have withholding tax deducted?
Yes, they're separate. GST (15%) is added on top of your fee if you're registered. Withholding tax is then deducted by the payer from the payment. Show both as distinct lines so your records reconcile at year end.
Should I invoice a day rate or hourly?
Either is standard for NZ IT contracting. Day rates suit ongoing engagements; hourly suits variable work. Reference the period or sprint so the client can match the invoice to delivered work. See our contractor rate calculator to set the number.
