Withholding tax deductions
In some industries, the IRD require employers to deduct and pay to the IRD withholding tax on behalf of their independent contractors.
The tax rate is generally 15% to 20% but if the contractor refuses to supply an IRD number or tax code declaration the rates vary from 25.5% to 45% depending on the industry.
The contractor must supply the employer with an IRD form “IR330” which details his name, IRD number, WT code and the rate of tax to be deducted. Page 4 of the IR330 shows the rates for various industries.
The employer is required to forward the WHT to the IRD each month as part of their employer return.
The tax code that a contractor must use is “WT”
Using the WT tax code means the employer does not pay ACC levies on behalf of the contractor, the contractor pays these themselves.
When a contractor who has Withholding Tax Deduction issues an invoice to the employer it must show the WHT
to be deducted and the GST if the contractor is GST Registered.
Both the GST and WHT must be calculated on the gross amount. The example below shows the steps required to complete an invoice correctly
Step 1 Calculate Gross Value Of Goods Or Services
Step 2 Calculate The GST & WHT On Gross Value – $400 * 15% GST = $60.00 (If GST Registered) $400 * 20% WHT = $80.00 (Check % Applicable).
Step 3 Deduct WHT From Gross Amount
Step 4 Show Sub Total
Step 5 Add GST (If GST Registered)
Step 6 Show Total
Sample Invoice Where Withholding Tax (WHT) Is Deducted.
– 10hrs @ $40.00 400.00
– Less WHT -80.00
– Sub – Total 320.00 GST 60.00
In the above example the employer would pay $380 to the contractor and $80 to the IRD as WHT The contractor would pay $60 to the IRD as GST and when his Income Tax is calculated at the end of the year there will be a $80 credit at the IRD towards his taxes.
A WORD OF CAUTION! We have found instances where the employer has been required to pay WHT
to the IRD as their industry has to deduct it and our client (the contractor) has deducted WHT from
their invoice but the employer has not passed it to the IRD believing they don’t have to.
This has left the contractor effectively underpaid by the employer by the amount of WHT and at the end of the year they have to pay tax on the full amount.
When starting work for a new employer, the contractor should ascertain that the employer is registered with the IRD as an employer and returns the WHT to the IRD. A necessary step here for the contractor is to ensure he gives the employer a completed copy of the IR330 form.
