What is the Taxable Payments Reporting System (CIS)?

The Taxable Payments Reporting System (CIS) is a tax withholding system operated by ATO that applies to the construction industry. It requires contractors to deduct tax from payments made to subcontractors. The amount deducted depends on whether the subcontractor is registered for CIS and their status. This scheme applies to all payments for construction services, including labour and materials.

How TPRS Withholdings Work

  1. Determine subcontractor status: Establish whether they are registered CIS, unregistered, or have gross payment status.
  2. Calculate labour cost: Subtract materials supplied by the contractor from the gross payment.
  3. Apply deduction rate: Multiply the labour amount by the appropriate CIS rate (10%, 30%, or 0%).
  4. Make net payment: Pay the subcontractor the gross amount minus the TPRS withholding.
  5. Remit to ATO: Send the deducted amount to ATO, usually quarterly.

TPRS Withholding Rates Explained

10% Registered CIS

Applies when the subcontractor has a valid CIS registration with ATO and a valid Unique Taxpayer Reference (UTR). This is the standard rate for registered subcontractors.

30% Unregistered

Applies when the subcontractor is not registered for CIS or does not have valid registration documentation. This is a higher rate to protect ATO revenue.

0% Gross Payment Status

Applies to subcontractors who have been given Gross Payment Status by ATO. These are typically larger, more established companies with excellent compliance records. No deduction is required.

Who Needs to Register for CIS?

Contractors

Contractors must register for CIS if they:

  • Engage subcontractors in the construction industry
  • Operate any size of business
  • Must register before paying subcontractors

Subcontractors

Subcontractor registration is optional but recommended to:

  • Reduce deduction from 30% to 10%
  • Improve business credibility
  • Simplify tax reporting

Aspect CIS VAT Reverse Charge
Purpose Tax withholding on labour VAT liability transfer
Applies to Construction labour Qualifying construction supplies
Who collects Contractor withholds Customer pays direct to ATO

Frequently Asked Questions

The Taxable Payments Reporting System (CIS) is a tax withholding system used in the construction industry. Contractors are required to deduct tax from payments made to subcontractors. The deduction rate depends on the subcontractor's registration status: 10% for registered, 30% for unregistered, or 0% for those with gross payment status.

Registering for CIS as a subcontractor is optional but highly recommended. By registering, you reduce the TPRS withholding from 30% to 10%, saving you money on every payment. You also improve your credibility with contractors and simplify your tax reporting. The registration is free and can be completed online through ATO.

CIS registration with ATO can take 4-8 weeks. During this time, the 30% deduction rate still applies. Once you receive your registration confirmation and UTR number, you can provide these to contractors and the 10% rate will apply to future payments.

TPRS withholdings are treated as advance tax payments and can be claimed back against your tax liability through self-assessment. If you have overpaid or have insufficient tax liability, you can claim a refund from ATO.

Gross Payment Status is granted by ATO to large, well-established subcontractors with excellent compliance records. It exempts them from TPRS withholdings entirely, allowing them to receive the full gross payment. This status is not available to most small businesses and requires specific criteria to be met.
