Struggling to Save for GST? You’re Not Alone (And You’re Not Bad at Business)

For many startups, creatives, and small business owners, GST is one of the hardest parts of running a business because it quietly drains cash if it’s not managed well.

Here are practical, proven ways to make GST far less painful.

1. Separate GST From Your “Real” Money

One of the simplest and most effective strategies is to set up a dedicated GST bank account.

Each time money comes into the business, transfer the GST portion (usually 15% or 1/9th of income received) straight into that account. That way:

  • GST is never mistaken for profit

  • Your main account shows what you can actually spend

  • Filing time becomes boring (which is exactly what we want)

2. Automate Where Possible

If remembering to move GST relies on motivation, it will eventually fail.

Options include:

  • Automatic bank rules that sweep a percentage of income into a GST or tax account

  • Treating GST like PAYE — it leaves the account before you pay yourself

  • Weekly or fortnightly transfers instead of scrambling at the due date

3. Treat GST Like a Bill, Not a Surprise

GST isn’t optional, and it’s not negotiable — so it helps to treat it like rent or power.

This could mean:

  • Setting aside money each month toward the expected GST bill

  • Checking “GST owed if filed today” in your accounting software regularly

  • Planning for it well before the return is due

4. Make Sure Your Accounting Is Actually Correct

From a technical perspective:

  • GST is only payable once you’ve provided a taxable supply

  • Deposits, progress payments, and timing differences can affect when GST is due

  • Incorrect treatment can mean paying GST earlier than required

From a practical perspective:

  • Business expenses paid privately are often missed

  • Missed expenses = higher income tax and less GST claimed

  • That’s money unnecessarily left on the table

5. Maximise Legitimate Deductions

If cash flow is tight, GST can feel heavier than it needs to.

Making sure you’re:

  • Capturing all business-related expenses

  • Correctly apportioning mixed-use costs

  • Recording reimbursements for personal spending on the business

6. Choose the Right Filing Frequency

Monthly, two-monthly, or six-monthly GST returns all suit different types of businesses and personalities.

Smaller, more frequent payments can be easier for some. Others need longer cycles, but only if they have a solid saving system in place.

This is about matching the structure to how you actually operate, not what you “should” be able to do.

If GST is a constant source of stress in your business, that’s usually a sign it’s time for better systems, not more discipline.
