Employee share schemes are increasingly common across Australian startups, listed companies, and professional services firms — and they create a set of bookkeeping and payroll obligations that differ significantly from ordinary salary and wages, with the taxing point rules being the most critical and the most frequently misunderstood.
Division 83A of the Income Tax Assessment Act 1997 governs the tax treatment of employee share scheme (ESS) interests. Bookkeepers acting for employers who operate an ESS need to understand both the employer's accounting obligations and the PAYG withholding rules that apply when the taxing point is reached.
The Two Taxing Points: Upfront vs Deferred
An ESS interest — which can be a share, option, right, or stapled security — is taxed at one of two points depending on the scheme structure:
Upfront taxing point (Division 83A-B): The default position. The employee is taxed in the income year in which the interest is acquired. The taxable amount is the discount — the difference between the market value of the interest at the acquisition date and the amount the employee paid (if any).
Deferred taxing point (Division 83A-C): Applies where the scheme satisfies specific conditions, including: the interests are subject to a genuine risk of forfeiture or a disposal restriction, and the employer has made an election to use the deferred taxing arrangement. Under deferred treatment, the tax is triggered at the earliest of: when the real risk of forfeiture or disposal restriction ceases, when the employee ceases employment, or 15 years after acquisition.
For employers, the distinction matters because it determines when PAYG withholding must be remitted and when the associated payroll tax and super obligations arise.
The $1,000 ESS Discount Exclusion
Under section 83A-35 of the ITAA 1997, eligible employees can receive an ESS discount of up to $1,000 that is excluded from assessable income in a given income year. This concession applies only where:
- The scheme is available to at least 75% of permanent Australian-resident employees who have completed three or more years of service
- The scheme is not discriminatory (i.e., it broadly benefits the workforce rather than targeting executives)
- The employee's adjusted taxable income does not exceed $180,000 in the year
Where the $1,000 exclusion applies, only the discount in excess of $1,000 is included in the employee's assessable income. For example, an employee who receives shares worth $3,200 for nil consideration has a discount of $3,200, of which $1,000 is excluded and $2,200 is taxable.
Bookkeepers should check the scheme documentation to confirm whether the employer has designed the scheme to qualify for this exclusion. It is a valuable employee tax benefit, but it requires specific structural features that not all ESS arrangements satisfy.
Recording the Shares on the Employer's Books
From the employer company's perspective, the issue of shares under an ESS creates equity transactions, not expense transactions — with one significant exception.
For a company issuing new shares: The issue of shares to employees at a discount is recorded as:
- Debit Share-Based Payments Expense (or Employee Benefits Expense)
- Credit Share Capital (at fair value) or Contributed Equity
The expense represents the fair value of the services received from the employee in exchange for the equity instrument. Under AASB 2 Share-based Payment, the cost is measured at the grant date fair value of the equity instruments issued, not the market value at vesting.
For an employer purchasing existing shares on-market for employees: The employer buys shares and holds them as a treasury instrument until vesting. The journal is:
- At purchase: Debit ESS Asset (or Prepaid Compensation), Credit Cash
- At vesting: Debit Employee Benefits Expense, Credit ESS Asset
For option plans: No shares are issued at grant; they are issued only on exercise. The option expense is spread over the vesting period using AASB 2 valuation methodology.
Bookkeepers who are not managing the statutory financial accounts may not need to apply AASB 2 in full — but they should at a minimum be aware that the cash outflow for purchasing shares is not an operating expense at the time of purchase, and that the ESS discount has tax implications that trigger payroll obligations.
PAYG Withholding for ESS Interests
Where the taxing point of an ESS interest falls in the current income year, the employer has PAYG withholding obligations. The ATO's ESS withholding rules (Schedule 1, Part 2-5 of the Taxation Administration Act 1953) require:
- The employer must withhold tax from any ESS discount amount that constitutes ordinary income
- The withheld amount must be remitted to the ATO through the employer's regular PAYG withholding cycle
- The ESS discount and associated PAYG withholding must be reported in the employer's Single Touch Payroll data for the relevant income year
The ESS annual report is a separate lodgement obligation. Employers must lodge an ESS Annual Report with the ATO by 14 August following the end of the income year. This report details the number of interests provided, the discount amounts, and the employees who received them. Failure to lodge attracts penalties.
From a payroll coding perspective, ESS income is typically coded separately from ordinary wages in the STP reporting framework. Most payroll software has a dedicated ESS income type — confirm that the correct income type code is selected so that the ATO's data-matching of employee tax returns and employer ESS reports reconciles correctly.
Practical Checklist for ESS Bookkeeping
At each ESS vesting date or taxing event:
- Confirm whether the taxing point is upfront or deferred and which income year applies
- Calculate the discount amount per employee (market value at taxing point less amount paid)
- Apply the $1,000 exclusion if the scheme qualifies
- Calculate PAYG withholding on the net taxable discount
- Record the payroll journal including ESS income and PAYG withholding
- Remit PAYG withholding through the regular payroll cycle
- Update STP payroll data with ESS income type
- Flag the ESS Annual Report obligation on the client's compliance calendar (due 14 August)
ESS arrangements vary enormously — startup options, listed company rights plans, and small business employee share schemes each have different structural features. When in doubt, refer the employer to a tax adviser for scheme-specific guidance before coding the transactions.
