RCTI Rules for AU Builders Paying Subcontractors — A Step-by-Step Compliance Walk-Through

Recipient Created Tax Invoices (RCTIs) are a quietly important compliance area for AU construction operators. When a builder generates the tax invoice on behalf of a subcontractor (instead of the subcontractor invoicing the builder), the transaction is technically a "Recipient Created Tax Invoice" — and it's only valid under specific ATO conditions documented in GSTR 2000/10.

Get the RCTI process right and you streamline subcontractor payment workflow, smooth GST reconciliation, and reduce administrative back-and-forth. Get it wrong and your input tax credits become disallowable on audit — meaning the ATO can deny GST credits on subcontractor spend years after the fact.

This is the step-by-step compliance walk-through for AU builders, EPC contractors and trade-business operators using RCTIs for subcontractor payments.

What an RCTI is — and why builders use them

Normally, the supplier (the subcontractor) issues a tax invoice to the recipient (the builder) for the supply of services. The recipient pays the invoice.

An RCTI inverts this: the recipient (the builder) issues the tax invoice on behalf of the supplier (the subcontractor). The builder calculates the value, GST, and issues a single combined claim + payment certificate.

For construction operators paying 10-50 subcontractors per project across multiple projects, RCTIs are operationally compelling:

• Builder controls the invoice timing (aligned with progress claim cycle)

• Eliminates back-and-forth on amounts (the builder calculates from agreed schedules)

• Reduces subcontractor admin burden (they don't need to invoice)

• Aligns RCTI lodgement with builder's BAS cycle

• Improves cash-flow visibility (builder knows exactly when payments hit)

The eligibility tests under GSTR 2000/10

RCTIs are NOT available for every recipient-supplier relationship. The ATO restricts RCTI use to specific scenarios. For construction operators, eligibility is met when:

1. Both parties are registered for GST

2. Both parties have an ABN

3. The subcontractor relationship falls within an RCTI-eligible class per GSTR 2000/10 — for construction, this is typically "professional services" or "construction services" supplied to a head contractor

4. Written agreement in place BEFORE the first RCTI is issued, documenting both parties' consent to the RCTI arrangement

5. Subcontractor agrees not to issue their own tax invoice for the same supply

The written agreement (point 4) is the most-commonly missed compliance point. Without it, the RCTI is not a valid tax invoice — and the builder's input tax credit claim can be disallowed on audit.

Step-by-step: setting up RCTI compliance

Step 1: Confirm subcontractor GST + ABN status

Before the first RCTI, verify:

• Subcontractor's ABN via abr.business.gov.au (ABN Lookup)

• Subcontractor's GST registration status (visible via ABN Lookup)

• Subcontractor's legal name matches the entity you're contracting with

Save a screenshot or print-to-PDF of the ABN Lookup result. This becomes the documentation.

Step 2: Establish the written RCTI agreement

The written agreement must be in place BEFORE the first RCTI is issued. It can be:

• A clause in the master subcontract agreement (most common)

• A separate signed "RCTI Agreement" document

• An exchange of emails where both parties confirm consent

Required elements per GSTR 2000/10:

• Identification of both parties (legal names + ABNs)

• Statement that the recipient will issue RCTIs for supplies under the agreement

• Statement that the supplier will NOT issue their own tax invoice for the same supplies

• Confirmation both parties are GST-registered

• Agreement to notify if GST registration status changes

Template clause for inclusion in subcontract agreements:

"The Builder and the Subcontractor agree that the Builder will issue Recipient Created Tax Invoices in respect of all taxable supplies made by the Subcontractor under this Subcontract. The Subcontractor will not issue tax invoices in respect of the same supplies. Both parties confirm they are registered for GST and will notify the other party within 7 days if their GST registration status changes."

Step 3: Generate the RCTI at each progress claim

The RCTI must include all standard tax invoice elements per ATO requirements:

• The words "Recipient Created Tax Invoice" prominently displayed

• Builder's ABN + name

• Subcontractor's ABN + name

• Date of issue

• Brief description of supplies

• GST-exclusive amount + GST amount + GST-inclusive amount

• If multiple supplies on one RCTI, total GST and total GST-inclusive amount

Most construction operators integrate RCTI generation with their progress-claim certification process. The progress claim certificate doubles as the RCTI when formatted correctly.

Step 4: Deliver the RCTI to the subcontractor

The RCTI must be delivered to the subcontractor — typically via email at the same time as payment is made. The subcontractor uses this document for their own BAS (claiming GST output liability) just as if they had issued the invoice themselves.

Step 5: Retain documentation for 5 years

For each RCTI: retain the signed written agreement, the RCTI document, ABN Lookup screenshot, and proof of delivery (email receipt) for at least 5 years post-issue. The ATO can audit RCTI compliance retrospectively.

What happens if RCTI compliance fails

If the ATO audits and finds the RCTI was not validly issued (no written agreement, supplier not GST-registered, etc.):

1. The RCTI is not a valid tax invoice

2. The builder's input tax credit claim on that RCTI is disallowed

3. The builder must repay the disallowed GST + interest + potentially penalty

4. For a $5M subcontractor spend across invalid RCTIs, the GST recovery could be ~$455k + interest + penalty — a six-figure remediation

The ATO has progressively tightened RCTI audit attention since 2022. We've seen RCTI compliance gaps surfaced as part of broader construction-industry compliance reviews.

Six common mistakes we fix in first-quarter engagements

1. No written agreement before the first RCTI. Most common failure. Builders inherit a contractor pool from previous management and don't realise the RCTI agreement wasn't established.

2. Subcontractor not GST-registered. Builder issues RCTIs for sub-$75k revenue contractors who haven't registered. Invalid.

3. ABN status not monitored. Subcontractor cancels GST registration mid-engagement. Builder keeps issuing RCTIs. The post-cancellation RCTIs are invalid.

4. RCTI doesn't include the required "Recipient Created Tax Invoice" label. Document technically not an RCTI without the label.

5. Subcontractor also issues their own tax invoice. Both parties trying to claim — agreement explicitly prohibits this.

6. Documentation not retained. 5-year retention period missed. When audit happens, builder can't produce the underlying RCTI agreements.

RCTI vs Subcontractor Statement (NSW SOPA + similar state schemes)

For NSW Security of Payment Act compliance (and similar state schemes), subcontractors have rights to issue "Payment Claims" with statutory force. These are NOT the same as RCTIs.

• Payment Claim under SOPA: a statutory document the subcontractor issues to enforce payment

• RCTI: a tax invoice the builder issues on behalf of the subcontractor (typically AFTER the SOPA process is concluded)

The two systems can coexist. The subcontractor issues a Payment Claim (which is not a tax invoice). The builder responds with a Payment Schedule. After the SOPA dispute is resolved, the builder issues the RCTI for the agreed amount.

Where this fits in a TechEdge engagement

• Finance Manager (from $2,750/mo): RCTI agreement template provision, monthly RCTI compliance check, ABN status monitoring.

• Financial Controller (from $4,950/mo): All the above plus formal RCTI process documentation, integration with progress claim certification workflow, annual RCTI compliance audit (internal).

• Head of Finance (from $8,500/mo): All the above plus contract template review (RCTI clauses in master agreements), ATO ruling requests for borderline cases, dispute resolution support.
