The Difference Between Pre-Tax And Post-Tax Deductions

Blue Orchid Accounting • September 26, 2022

If you’re offering benefits to your employees, you’re likely wondering how you can withhold wages for the proper benefits, and whether you do so before or after taxes. Understanding the difference between pre-tax and post-tax deductions is crucial – and that’s why we’re here to help. We’ve put together this helpful guide to clear up the distinction between these deductions and how to navigate them properly.


Pre-Tax Deductions


Pre-tax deductions are withheld from your employee’s wages before tax, and they reduce the income that your employee will need to pay tax on.


Common pre-tax deductions include:


  • Retirement plans and superannuation
  • Salary sacrifice items, such as laptops and cars
  • Life and health insurance
  • Transportation programs and parking expenses
  • Medical expenses


Let’s look at some particular common deductions in more detail.


Work Place Giving Deductions


If your employee regularly donates to charitable organisations, they can claim these donations as a pre-tax or post-tax deduction. If they plan to donate before tax, the amount they donate reduces the total pay which attracts withholding tax. If they give their donation post-tax, their taxable income won’t be reduced and they might opt for claiming their donation as a tax deduction when compiling and submitting their tax return.


Salary Sacrifice Superannuation Deductions


Within these deductions, your employee sacrifices a determined amount or a percentage of your wages pre-tax, which is paid into their superannuation fund. The sacrificed amount doesn’t reduce the employer’s superannuation payments.


Results Of Pre-tax Deductions


Once these items are deducted from an employee’s pay, the government then calculates the total tax payable.


Pre-tax deductions result in lower tax obligations for you and your employee, though your employee may end up owing tax when they use these benefits. Not all benefits are exempt from federal, state and local taxes, so it’s important you check relevant legislation to ensure you’re aware of what’s involved.


Post-Tax Deductions


Post-tax deductions are withheld after you withhold taxes from your employee’s wages, and they’ll have no impact on your employee’s taxable income.


Common post-tax deductions include:


  • Retirement plans
  • Life and disability insurance
  • Union wages


Let’s consider some of these deductions in more detail.


Union Or Professional Association Fees


These are deductions in which employees contribute towards their membership of a professional organisation or union body.


Child Support


Child support payment deductions are drawn from wages and paid through Services Australia. Child support payment deductions consider a portion of an employee’s wages as a Protected Earnings Amount (PEA), which remains free from withholding.


Results Of Post-Tax Deductions


Post-tax deductions are subtracted following payroll tax deductions. Both you and your employee will end up owing more payroll tax, but your employee won’t incur tax on the benefits when using them down the line. As you withhold taxes before benefit contributions, all taxes at federal, state and local levels are already paid.


Applying These Deductions


There are clear distinctions between pre-tax and post-tax deductions.


With pre-tax deductions, as your employee will need to pay tax on a lower income, they’ll attract a greater net pay. This can be especially helpful if a person has significant upfront expenses, such as rent, groceries, and medical bills.


Post-tax deductions result in a person paying more in tax down the line and receiving a lesser net pay. They will, however, not need to owe taxes in the future as they’ve already contributed these deductions.

Taking money or other benefits from a private company is not always as simple as making a withdrawal. Under Australia’s Division 7A tax rules, certain payments, loans and forgiven debts can be treated as taxable dividends. Here is a practical overview of how Division 7A works and how private business groups can manage the risk. What is Division 7A? Division 7A is designed to prevent shareholders and their associates from accessing private company profits without paying the appropriate tax. It applies mainly where a private company provides a financial benefit to: A shareholder; or An associate of a shareholder, such as a spouse, relative, family trust or related entity. If Division 7A applies, the benefit may be treated as an unfranked dividend. This means the recipient may need to include the amount in their assessable income without receiving a franking credit. What transactions can trigger Division 7A? Division 7A can apply to more than straightforward cash withdrawals. Common risk areas include: Payments A payment may include: Paying a shareholder’s private expenses; Paying personal credit-card balances; Transferring company property below market value; Paying school fees or mortgage expenses; or Providing company assets for private use. Recording a payment as a “shareholder drawing” does not prevent Division 7A from applying. Loans and advances Division 7A may apply where a private company lends money to a shareholder or associate and the amount is not repaid before the company’s lodgment day. The lodgment day is generally the earlier of: The due date for the company’s tax return; and The date the return is actually lodged. This means lodging the company return early may bring forward the deadline for addressing the loan. Forgiven debts Division 7A may also apply where the company forgives a debt owed by a shareholder or associate. A formal debt release is not always required. Risk can arise where the company writes off the amount or acts in a way that suggests it does not intend to collect the debt. How can a company loan avoid becoming a deemed dividend? A shareholder loan can generally avoid an immediate Division 7A dividend if it is placed under a complying written loan agreement before the company’s lodgment day. A complying loan ordinarily requires: A written and legally effective agreement; Interest charged at no less than the annual Division 7A benchmark rate; A maximum term of seven years for an unsecured loan; or A term of up to 25 years for a qualifying loan secured by a registered mortgage over real property. The ATO’s benchmark interest rate for the 2026–27 income year is 8.77%. Because the benchmark rate changes annually, businesses should update their loan calculations each year. Minimum yearly repayments Once a complying Division 7A loan is established, the borrower must generally make a minimum yearly repayment from the following income year. The repayment is calculated using: The opening loan balance; The benchmark interest rate; and The remaining term of the loan. If the borrower pays less than the required amount by 30 June, the shortfall may be treated as an unfranked dividend. Businesses should also avoid temporary or circular repayments. For example, a shareholder should not repay a company loan immediately before 30 June and then borrow the money back shortly afterwards. Division 7A contains rules that may disregard these repayments. What is distributable surplus? A Division 7A dividend is generally limited to the company’s distributable surplus. Distributable surplus is calculated using a statutory formula based broadly on the company’s net assets, subject to specific adjustments. It is not necessarily the same as: Accounting profit; Retained earnings; Cash held by the company; or The balance of the company’s franking account. Market values and the legal character of assets and liabilities may affect the calculation. For this reason, businesses should prepare a documented distributable-surplus calculation rather than relying only on the balance sheet. Division 7A and family trusts Division 7A can also affect trust structures. A common arrangement occurs where a trust distributes income to a private company but does not immediately pay the amount. This is commonly referred to as an unpaid present entitlement, or UPE. In June 2026, the High Court delivered its decision in Commissioner of Taxation v Bendel. The Court found that the UPEs in that particular case were not loans made by the corporate beneficiary to the trustee for the purposes of section 109D. However, Bendel does not mean that all UPEs are automatically outside Division 7A. The trust deed, distribution resolutions and subsequent use of the funds remain important. Separate Division 7A provisions may apply if the trust provides payments, loans or other benefits to the company’s shareholders or their associates. Private groups with corporate beneficiaries should therefore review existing UPE arrangements in light of Bendel and the ATO’s updated position. Can a Division 7A mistake be corrected? The Commissioner has discretion under section 109RB to disregard a deemed dividend, or allow it to be franked, where the Division 7A outcome arose from an honest mistake or inadvertent omission. Relief is not automatic. The ATO may consider: How the mistake occurred; Whether reasonable care was taken; The taxpayer’s compliance history; and Whether appropriate corrective action was completed. Corrective action may involve repayments, interest, amended accounts, loan documentation or amended tax returns. Documents should never be backdated or created to support transactions that did not actually occur. Practical steps for business owners Division 7A should be reviewed throughout the year—not only when the company tax return is prepared. A practical compliance process should include: Reconciling shareholder and director loan accounts; Identifying private expenses paid by the company; Reviewing benefits provided to shareholders and family members; Documenting new loans before the company’s lodgment day; Calculating minimum yearly repayments; Confirming repayments have cleared by 30 June; Checking the source of repayment funds; Preparing a distributable-surplus calculation; and Reviewing trust distributions and UPEs. The bottom line Division 7A can turn an informal payment, loan or accounting entry into an unfranked taxable dividend. The best risk-management strategy is to identify transactions early, maintain effective documentation and review all shareholder and related-party accounts before 30 June and before lodging the company’s tax return. Division 7A is highly fact-dependent. Business owners should obtain professional advice before implementing or correcting a private company or trust arrangement.
