Offset account setups that actually work for sole traders

For sole traders working from home, the best offset setup is simple: keep business and ATO money away from your home loan, and pay yourself a steady “wage” into a clean offset-linked personal account. That usually means three main accounts: business trading, tax/GST holding, and a personal everyday account feeding your offset.

This structure keeps lenders happy, protects your family home from business risk, and still lets you smash down interest.

A three-account structure keeps your offset clean and lenders comfortable.

The core setup: three accounts plus your offset

For most home‑based sole traders, a three‑account structure works best:

1. Business trading account – all client income in, business expenses out.
2. Tax/GST/PAYG holding account – ring‑fence ATO money as it comes in.
3. Personal everyday account + linked offset – your “salary” lands here and flows into the offset.

This is the same discipline lenders love to see in your bank statements over 3–6 months. It’s also consistent with the three‑account model we use in /insights/red-flags-mixed-business-personal-accounts-spook-lenders-fix.

How the money should flow

• Step 1 – Client pays invoice into your business trading account.
• Step 2 – Move the tax/GST portion (often 25–35% of income, depending on your rate and GST) into your tax holding account.
• Step 3 – Transfer a fixed “wage” (say $4,500 a month) from business to your personal everyday account.
• Step 4 – Sweep surplus from your personal account into the offset each week or month.

ATO money never touches your offset. Business expenses never come from your offset. That’s the key discipline.

Why not just run everything through the offset?

Mixing business and personal in your offset looks clever short‑term but creates three big problems:

1. Lenders see a risky business. Regular transfers from offset/redraw to cover BAS, wages or stock are a red flag that the business can’t self‑fund core costs.
2. ATO money gets spent. When GST and PAYG sit in the same offset you buy groceries from, the next BAS can hurt badly.
3. Tax tracing gets messy. It becomes harder for you and your accountant to prove what’s deductible, especially if you ever convert the home to an investment later.

We’ve seen many self‑employed clients in this position when reviewing their banking for a home loan. Cleaning it up is often step one before we apply, as explained in /insights/structuring-business-personal-accounts-lenders-see-real-income.
