# ABN Subcontractor Requirements Guide for Australian Contractors

This guide outlines the practical requirements for onboarding ABN subcontractors in the construction industry, focusing on day-hire arrangements and compliance obligations.

## 1. Accounting System Requirements (Xero/MYOB)

### Essential Information Needed:
- **ABN** (Australian Business Number) - Must be valid and active
- **Legal Name** - Must match ABN registration exactly
- **Trading Name** (if different from legal name)
- **Contact Details** - Address, phone, email
- **Bank Account Details** - BSB and Account Number
- **GST Registration Status** - Registered or not registered
- **TFN** - Not required for ABN subcontractors (only for employees)

### Xero/MYOB Setup:
- Set up as a "Supplier" or "Contact" (not as an employee)
- No PAYG withholding required if they provide a valid ABN
- Mark as "TPAR Reportable" for construction services
- No superannuation guarantee obligations for genuine contractors

### TPAR (Taxable Payments Annual Report):
- Required for construction businesses paying contractors
- Report all payments made to ABN subcontractors annually
- Due 28 August each year
- Include: contractor name, address, ABN, total payments, GST

## 2. Due Diligence and Verification

### ABN Lookup Checks:
- **Verify ABN is valid and active** - Use ABN Lookup website or app
- **Confirm legal name matches** - Invoices must use legal name from ABN record
- **Check GST registration status** - Determines if GST should be charged
- **Document verification** - Screenshot/print ABN record for file

### Red Flags to Watch For:
- ABN not in contractor's personal name (for sole traders)
- Inactive or cancelled ABN
- Name discrepancies between ABN and invoices
- Refusal to provide ABN

### When ABN Not Provided:
- Must withhold 47% tax from payments (PAYG withholding)
- Report withheld amounts to ATO
- No tax deduction for payment if withholding requirements not met

## 3. Insurance Requirements

### Public Liability Insurance:
- **ABN subcontractors MUST have their own** public liability insurance
- Contractor's insurance does NOT cover ABN workers
- Minimum $5M recommended for construction work
- Request certificate of currency before work commences
- Verify coverage includes type of work being performed

### Professional Indemnity (if applicable):
- Required for design or advisory work
- Depends on nature of services provided

### Tool and Equipment Insurance:
- ABN workers responsible for their own tools/equipment
- Consider if working with expensive machinery

## 4. Workers Compensation in NSW

### Key Principle:
- **Having an ABN does NOT automatically make someone a contractor** for workers compensation purposes
- NSW uses multiple factors to determine worker status

### Contractor vs Worker Test:
Factors indicating contractor status:
- Can delegate/subcontract work
- Provides own tools and equipment
- Paid for result achieved, not time worked
- Has right to accept/decline work
- Bears commercial risk
- Markets services to public

### Workers Compensation Obligations:
- **Generally NOT required** to cover genuine ABN subcontractors
- **May need coverage** if contractor is deemed a worker under NSW law
- Use SIRA's "Worker or Contractor Tool" for unclear cases
- Consider obtaining voluntary coverage for regular subcontractors

### Best Practice:
- Document the contractor relationship clearly
- Ensure contractors have their own personal accident insurance
- Regular subcontractors should consider income protection insurance

## 5. ABN Invoicing and Payment Best Practices

### Invoice Requirements (Tax Invoices over $82.50):
- Must include: "Tax Invoice" label
- Contractor's ABN
- Invoice date and number
- Description of services
- Total amount including GST (if registered)
- GST amount (if registered)
- For invoices $1,000+: Must include customer's identity or ABN

### Day-Hire Specific Practices:
- **Daily timesheets** - Even for ABN workers, good to track hours
- **Rate agreements** - Document hourly/daily rates in advance
- **Same-day invoicing** - Quick turnaround for day-hire work
- **E-invoicing** - Email invoices for faster processing

### Payment Terms:
- **Standard terms**: 7-14 days for construction day-hire
- **Early payment discounts**: Consider 2% for payment within 2 days
- **Late payment fees**: Clearly state in terms (typically 5-10% after 30 days)
- **Payment methods**: Bank transfer preferred, avoid cash

### Record Keeping:
- Keep copies of all invoices
- Maintain contractor files with ABN records
- Track payments for TPAR reporting
- Store insurance certificates
- Document rate agreements
