For many small businesses, December is a whirlwind. Sales spikes, staff holidays, client gifts, Christmas parties, and last-minute expenses make it an exciting month — but it can also create a January cash flow hangover that hits hard once the holiday rush is over.

At Tax Store, we see this pattern every year: businesses start the new year with slow sales, overdue bills, low cash reserves, and a sudden rush of ATO obligations. The good news? With a bit of holiday cash flow planning and smart financial management, you can protect your business cash flow and make January one of your strongest months instead of your most stressful.

Here are our top tips to help your small business stay cash-flow-ready this holiday season.

1. Forecast December and January Cash Flow Before the Rush
A simple small business cash flow forecast gives you a clear view of:

• Expected income and sales
• Holiday expenses and staff leave payouts
• Penalty rates and overtime costs
• BAS, PAYG, and superannuation deadlines
• Supplier payments due early January

By mapping out your post-Christmas cash flow, you can make informed decisions, delay non-essential spending, and avoid a January cash flow crunch.

2. Build a Holiday Cash Buffer

Even a small cash reserve can reduce financial pressure in January. If your business has had strong trading months, set aside enough to cover two to four weeks of core expenses, including rent, wages, utilities, and subscriptions.

A holiday cash buffer ensures you can meet essential payments without relying on late sales or short-term loans

3. Incentivise Early Payments from Clients
Late payments are especially painful during December and January. To protect your cash flow:

• Offer small early-payment discounts
• Provide faster payment options (Stripe, PayPal, Bank Transfers)
• Send email reminders before your holiday closure
• Require deposits for large jobs scheduled for January

4. Manage Holiday Staffing Costs Strategically

December often brings additional staffing costs:

• Penalty rates and overtime
• Casual or temporary staff
• Paid leave and public holiday loadings

Planning staffing early and setting efficient rosters ensures your business doesn’t overspend during the festive season. Clear communication of hours and leave policies is essential for smooth operations.

5. Review Subscriptions and Recurring Expenses

December is a great time to review business expenses:

• Cancel unused software subscriptions
• Replace old tools
• Avoid duplicate platforms
• Pause automatic

Eliminating unnecessary costs frees up cash to cover January expenses.

6. Manage Stock Carefully
For businesses with physical inventory, over-ordering in December can tie up cash and force discounts in January. Focus on products that actually sell, and align your stock levels with expected demand to maintain a healthy cash flow.

7. Communicate Operating Hours Early

Let your customers know:

• When your business will close for the holidays
• When you will reopen
• Cut-off dates for orders or services

Clear communication prevents last-minute work, encourages pre-holiday sales, and helps you manage cash flow into January.

8. Don’t Forget January ATO Obligations

Even during slow periods, tax obligations continue. Plan ahead for:

• Superannuation payments
• PAYG installments
• BAS preparation
• Payroll obligations

Being prepared ensures your post-Christmas cash flow isn’t suddenly drained by ATO deadlines.

9. Consider Short-Term Financing Before You Need It

The best time to secure a line of credit or overdraft is while your cash flow is strong, not when you’re under pressure. Having access to short-term financing gives your business flexibility during seasonal fluctuations.

10. Get Expert Guidance Early

A strategy session with your accountant can help you:

• Build a holiday cash flow plan
• Optimise tax outcomes
• Identify cost savings
• Review payroll and leave liabilities
• Prepare for the new year
