Bookkeeper for Electricians in Geelong: What Your Business Actually Needs

Why Electrical Businesses Have Specific Bookkeeping Needs

Running an electrical business in Geelong isn't just physically demanding — the financial administration carries its own set of compliance obligations that most generic bookkeepers miss. Between TPAR lodgements, subcontractor ABN verification, GST on materials and labour, and job-by-job cost tracking, electrical businesses have more moving parts than a standard service business.

Getting these wrong doesn't just create extra paperwork. It can mean ATO penalties, missed GST credits, and BAS figures that bear no resemblance to what the business actually owes or is owed. This post covers what good bookkeeping looks like for a Geelong electrical business.

TPAR: The Obligation Most Electricians Don't Know About

If your electrical business pays subcontractors — even occasionally — you are almost certainly required to lodge a Taxable Payments Annual Report (TPAR) each year.

TPAR is an ATO reporting obligation that applies to businesses in the building and construction industry (which includes electrical work) that make payments to contractors for work done on their behalf. Each year, by 28 August, you report:

• Each subcontractor's name and ABN
• Total gross amount paid to them during the financial year
• Total GST included in those payments

The ATO uses TPAR data to cross-check contractor income. If a contractor doesn't declare income that appears on multiple TPAR reports, they get flagged. For the business paying — that's you — failure to lodge attracts penalties starting at $313 per 28-day period late.

A good bookkeeper tracks all subcontractor payments throughout the year in Xero, so when August comes around, TPAR is generated accurately in minutes rather than reconstructed from memory.

Subcontractor Management in Xero

Beyond TPAR, the way you manage subcontractor payments day-to-day matters for both your BAS and your protection as a business owner. Here's what correct subcontractor handling looks like in Xero:

• ABN verification first: Before paying any subcontractor, check their ABN is valid at abr.business.gov.au. An invalid or cancelled ABN triggers the no-ABN withholding rule.
• Record as supplier bills: Each subcontractor invoice should be entered as a bill in Xero against that supplier's contact — not just a bank payment coded to an expense account. This creates the paper trail TPAR requires.
• No-ABN withholding: If a subcontractor cannot provide an ABN, you must withhold 47% of their payment. This withheld amount must be reported on your BAS (W4 field) and remitted to the ATO. Most bookkeepers never set this up correctly for clients who rarely encounter it.
• Separate account for subcontractor costs: Keep subcontractor labour separate from employee wages in your chart of accounts — they're treated differently for GST, payroll tax, and TPAR purposes.

GST for Electrical Businesses

Once your electrical business turns over $75,000 or more per year, GST registration is compulsory. Once registered, you must charge GST on taxable supplies (your labour and materials) and can claim GST credits on your business purchases.

The common GST issues we see in Geelong electrical business Xero files:

• GST on materials purchased vs materials on-sold: You charge GST when you sell materials to a client. You claim GST when you buy them from a supplier. Both need the correct code (GST 10%) in Xero — but they sit on opposite sides of your BAS (G1 vs G11).
• Bank fees coded as GST: Bank charges from your financial institution are input taxed, not GST-free. They should be coded as BAS Excluded. Coding them as GST (10%) means you're claiming credits you're not entitled to.
• Insurance premiums: Most insurance has a stamp duty component that is GST-free. If your insurance premium is $1,100, it might only contain $95 of GST rather than $100 — your bookkeeper needs to check each policy.
• Wage payments: PAYG withholding is handled through Single Touch Payroll, not your BAS. Wage payments in Xero must be coded as BAS Excluded — they are not a GST transaction.

Job Costing: Knowing Which Jobs Make Money

One of the most valuable things a bookkeeper does for an electrical business isn't compliance — it's helping you understand which jobs are actually profitable.

Job costing means tracking income and direct costs (labour time, materials, subcontractor costs) per job, so you can compare your quoted margin to your actual margin. A well-run Geelong electrical business knows:

• Their average gross margin by job type (residential, commercial, new construction vs maintenance)
• Which jobs consistently underperform — and why (usually materials waste or underpriced labour)
• Whether their charge-out rate covers actual costs when vehicle time, tool wear, and admin time are included

In Xero, job costing is set up through Tracking Categories — a feature most electricians never activate. Combined with job management software like Fergus or ServiceM8 (both of which integrate directly with Xero), you can see job-by-job P&L without any manual calculation.

Vehicle and Equipment Expenses

Vehicles and equipment are major cost categories for electricians — and they need to be handled correctly for both tax and GST purposes.

Vehicles: If your van or ute is used exclusively for work, 100% of operating costs (fuel, registration, insurance, repairs) are deductible and the GST is claimable. If there's any private use, only the business-use portion can be claimed. Your bookkeeper sets up the correct split in Xero and ensures the logbook or odometer records are being maintained.

Tools and test equipment: Items under the instant asset write-off threshold can be expensed in full in the year of purchase — rather than depreciated over several years. This threshold changes each financial year (check with your accountant), but for most small electrical businesses with an active ABN, the benefit of immediate expensing is significant. Your Xero chart of accounts should separate small tools (expensed immediately) from larger equipment (depreciated).

Payroll for Electrical Apprentices and Employees

Many Geelong electrical businesses employ apprentices or additional licensed electricians. Payroll compliance for electrical businesses includes:

• Award identification: Most electrical employees are covered by the Electrical, Electronic and Communications Contracting Award (MA000025). Pay rates, overtime rules, and allowances must be correctly applied.
• Single Touch Payroll (STP): Every pay run must be reported to the ATO via STP — Xero handles this automatically once payroll is set up correctly.
• Superannuation: Super must be paid at 11.5% of ordinary time earnings (rising to 12% from 1 July 2025) quarterly at minimum — and from 1 July 2026, it must be paid on each payday (Payday Super). Late super becomes SGC, which attracts penalties and loses deductibility.
• Apprentice wages and PAYG: Apprentice pay rates vary by year of apprenticeship. PAYG withholding must be calculated correctly based on the apprentice's tax file number declaration and applied at each pay run.

What a Bookkeeper Actually Does for an Electrical Business

If you're currently doing your own books (or leaving them until BAS time), here's what a Geelong electrical business bookkeeper handles month-to-month:

• Bank reconciliation — every transaction matched, categorised, and coded correctly in Xero
• Subcontractor payment recording and ABN verification
• TPAR preparation throughout the year — so August lodgement is simple
• Quarterly BAS preparation and lodgement via a Registered BAS Agent (with agent extension dates — typically 4 weeks later than the standard deadline)
• Payroll processing via STP — including apprentice awards and super
• Monthly P&L review — so you know whether the business made money this month, not just at tax time
• Job cost reporting — which job types are profitable, which aren't

For most Geelong electrical businesses turning over $400k–$2M, this comes to 4–8 hours of bookkeeping work per month — a fixed monthly cost that's a fraction of what it would cost to do it yourself badly and fix it at year-end.
