Common ABN business expenses
Materials, supplies, subcontractor payments, equipment hire, vehicle costs, insurance, accounting, software, phones, and work tools can all be relevant.
Keep income and GST clear
Track contract income excluding GST separately from GST collected. If registered for GST, BAS records need to match your invoices and expenses.
Avoid mixing private costs
Use a separate bank account or bookkeeping file so private spending does not get mixed with business deductions.
