Business Savings vs Term Deposits: Where to Park Cash

Every business guide says the same thing: park spare cash somewhere it earns interest. The advice stops there, as if choosing between a business savings account and a business term deposit is a trivial decision. It is not.

The real question is not "which has the higher rate" but "when do you need the money." A term deposit earning 0.5% more than a savings account is a poor choice if you need to break it early and pay a penalty that wipes out months of interest. Conversely, leaving $200,000 in a savings account earning a lower rate when you could safely lock away $150,000 for 6 months is leaving money on the table.

The Core Trade-Off: Rate vs Liquidity

Business savings accounts and term deposits are both deposit products protected by the Financial Claims Scheme (FCS), which guarantees up to {{config:fcs_guarantee:limit}} per account holder per ADI. The difference is how they handle access to your money.

Neither product is inherently better. The optimal choice depends on your business's cash flow predictability.

When a Savings Account Makes More Sense

A business savings account is the right choice when:

1. Your cash flow is unpredictable. If revenue arrives irregularly (project-based work, seasonal business), you need funds accessible at all times. Locking money in a term deposit creates refinancing risk if a large expense arrives unexpectedly.
2. You need operational liquidity. The cash is working capital, not surplus. It may be needed within days for payroll, supplier payments, or equipment.
3. The rate gap is small. If the difference between the best savings rate and the best term deposit rate is under 0.3% p.a., the liquidity benefit of the savings account may outweigh the marginal rate gain.
4. You are building a cash reserve. Business emergency funds should be accessible immediately. A term deposit defeats the purpose of an emergency buffer.

When a Term Deposit Makes More Sense

A business term deposit is the right choice when:

1. You have identified surplus cash. After covering 3-6 months of operating expenses in a savings account, any remaining cash is surplus. This surplus can safely be locked away.
2. You have a known future expense. If you need $100,000 for a lease payment in 6 months, a 6-month term deposit locks in the rate and ensures the money is there when needed.
3. You want rate certainty. In a falling rate environment, a term deposit protects against future rate cuts. If the RBA is expected to cut rates, locking in today's rate may be advantageous. The current cash rate is 3.85% p.a. with the next RBA meeting on 18 March 2026.
4. You run a trust or SMSF with strict cash mandates. Some structures require fixed-income allocations. Term deposits fulfil this requirement with zero credit risk (up to the FCS limit).

The Hybrid Approach: Splitting Your Cash

Most businesses should not choose one or the other. The optimal approach splits cash across both:

Step 1: Determine your operating reserve

Calculate your average monthly expenses (payroll, rent, suppliers, tax). Multiply by 3-6 months. This is your operating reserve - keep it in a business savings account for instant access.

Step 2: Identify genuine surplus

Anything above the operating reserve is surplus. This cash can be deployed to earn a higher return without liquidity risk.

Step 3: Match term deposits to known future expenses

If you have a BAS payment due in 3 months, a 3-month term deposit matches the maturity to the expense. If you have no specific timeline, a rolling series of short-term deposits (the laddering strategy) reduces the risk of needing to break a deposit early.

Worked example (rates used for illustration)

Assume a business with $300,000 in cash, monthly expenses of $40,000, and a BAS payment of $50,000 due in 3 months.

Compare this to keeping all $300,000 in a savings account at 4.50%: annual interest of $13,500. The blended approach in this example earns slightly less, but provides rate certainty on $180,000 of the balance and ensures the BAS payment is covered.

The maths will vary depending on current rates and the size of the rate gap between savings and term deposits.

Tax Considerations for Business Deposits

Interest earned on business deposits is taxable income for the business. Key considerations:

• Company tax rate: Small businesses (under $50 million turnover) pay 25% company tax. Interest of $10,000 results in $2,500 in tax.
• Trust distributions: For businesses operating as trusts, interest income can be distributed to beneficiaries in lower tax brackets.
• TFN withholding: If you have not provided a TFN to the deposit institution, they may withhold tax at the top marginal rate. Ensure your business TFN is registered with all deposit providers.
• GST: Interest income is a financial supply and is GST-free. However, it may affect your GST-free proportion for input tax credit purposes.

A Note on the Financial Claims Scheme

Both business savings accounts and term deposits are protected by the FCS up to {{config:fcs_guarantee:limit}} per account holder per ADI. If your business holds more than this amount, consider spreading deposits across multiple ADIs to maintain full protection. Read our full guide on the Government Deposit Guarantee.

The Bottom Line

The best place to park business cash is not a single product - it is a split. Keep your operating reserve in a business savings account for instant access. Lock genuine surplus in term deposits for a higher return. Match term deposit maturities to known future expenses. The goal is not to maximise the rate on every dollar, but to optimise the balance between earning interest and maintaining the liquidity your business needs to operate.
