Division 7A Calculator: How It Works

The Division 7A calculator works out the minimum annual loan repayment required under Australia’s tax rules when a private company lends money to a shareholder or their associate. You enter the loan balance, the benchmark interest rate, and the company’s distributable surplus, and the calculator returns the minimum repayment amount you must make by the lodgment deadline. This helps you avoid a deemed dividend, which would otherwise be taxed in the shareholder’s hands at their marginal rate.

Formula

The Division 7A minimum repayment is the larger of two amounts:

• Interest-only amount = loan balance × benchmark interest rate
• Distributable surplus (the company’s available profits for the year)

In symbols:

Minimum repayment = max(loan × rate, surplus)

Where:

• loan = the outstanding loan balance at the start of the income year (in AUD)
• rate = the ATO benchmark interest rate for that income year (as a decimal, e.g., 7.5% = 0.075)
• surplus = the company’s distributable surplus (in AUD)

The result is the minimum amount that must be repaid by the company’s lodgment deadline (usually 30 June or the due date of the company’s tax return). If the actual repayment is less, the shortfall is treated as a deemed dividend.

Worked Example

Using the defaults from the calculator:

• Loan balance = $100,000
• Benchmark rate = 7.5% (0.075)
• Distributable surplus = $50,000

Calculate the interest component:

Interest = $100,000 × 0.075 = $7,500

Compare with surplus: $50,000 is larger than $7,500, so the minimum repayment is $50,000.

The calculator shows:

• Minimum annual repayment = $50,000.00
• Interest component = $7,500.00
• Principal component = $50,000.00 – $7,500.00 = $42,500.00

So the shareholder must repay $50,000 by the deadline to avoid a deemed dividend.

When to Use This Calculator

Use this tool when you have a private company that has made a loan to a shareholder, director, or their family member (an “associate”) during the income year. The rules apply to loans made after 7:30pm AEST on 11 December 1997. You need the loan balance at the start of the year (or the date the loan was made if it was during the year), the ATO’s benchmark rate for that year, and the company’s distributable surplus.

The benchmark rate is published by the ATO each year. For the 2023-24 income year, it was 8.27%; for 2024-25, it is 9.27%. You must use the rate for the year the loan was made, not the current year.

How to Read the Result

The result is the minimum repayment you must make to avoid a deemed dividend. If you repay more than this, the excess reduces the loan balance further. If you repay less, the shortfall is treated as an unfranked dividend paid by the company, which is taxed in the shareholder’s hands at their marginal rate, and the company may also be liable for penalties.

Note that the repayment must be made by the company’s lodgment deadline (usually the due date of its tax return) to count for that year. If you miss the deadline, you cannot fix it by making a late repayment; the deemed dividend becomes unavoidable.

Common Mistakes and Pitfalls

• Using the wrong benchmark rate: The rate changes each year. Use the rate for the year the loan was made, not the current year.
• Ignoring the distributable surplus: The minimum repayment is the higher of interest and surplus. If the surplus is higher, you must repay that amount, even if it exceeds the interest.
• Forgetting to include all loans: Multiple loans from the same company to the same shareholder are aggregated for Division 7A purposes. You must consider the total.
• Assuming the loan is forgiven: If a loan is forgiven, it is treated as a dividend immediately, not as a repayment.
• Not considering the 7-year repayment rule: For loans made before 1 July 2018, there is a different repayment schedule. This calculator applies to loans made on or after that date, which follow the general rule of interest plus principal over 7 years (or longer if the loan is for a house or business asset).

Limitations of the Formula

The calculator uses the simplified formula: the minimum repayment is the higher of the interest-only amount and the distributable surplus. However, the actual Division 7A rules are more complex. For example:

• If the loan balance is less than the interest-only amount, the minimum repayment is the loan balance itself (you cannot repay more than you owe).
• If the loan is made partway through the year, the interest is calculated on a pro-rata basis.
• If the company has a distributable surplus of zero, the minimum repayment is the interest-only amount.
• There are special rules for loans used to acquire a dwelling or for certain business purposes, which may allow a longer repayment period.

This calculator gives a quick estimate, but for accurate compliance you should consult a tax professional or use the ATO’s own Division 7A calculator.

Frequently Asked Questions

What is the benchmark interest rate for Division 7A?

The benchmark rate is set by the ATO each year. For the 2024-25 income year, it is 9.27%. For the 2023-24 year, it was 8.27%. The rate is published on the ATO website and is based on the average yield on 10-year government bonds.

Can I use this calculator for loans made before 1 July 2018?

No. Loans made before that date are subject to different rules, including a 7-year repayment schedule that requires a minimum repayment of interest plus principal over 7 years. This calculator uses the post-2018 rules, which are simpler (interest plus principal over 7 years, but the minimum is the higher of interest and surplus). For older loans, consult the ATO’s specific guidance or a tax advisor.

What if the distributable surplus is negative?

If the distributable surplus is negative (i.e., the company has losses), the minimum repayment is simply the interest-only amount. The calculator uses the max() function, so it will correctly return the interest amount when the surplus is less than the interest.

Does the repayment have to be made in cash?

Yes, the repayment must be made in money or by set-off against a debt the company owes you. Other forms of payment, such as providing goods or services, do not count as repayment for Division 7A purposes.

What happens if I miss the repayment deadline?

If you do not make the minimum repayment by the company’s lodgment deadline, the shortfall is treated as an unfranked dividend. You cannot fix this by making a late repayment. The deemed dividend is taxed at your marginal rate, and the company may also face penalties.

Can I use a lower interest rate if the loan is from a related entity?

No. The benchmark rate is fixed by the ATO and cannot be negotiated. It is the same for all Division 7A loans, regardless of the actual interest rate charged. If you charge a higher rate, the excess is not a repayment; it is interest income for the company.
