Explained: Tax and Your Employee Share Scheme (ESS)

Being offered shares, options or other equity in the company you work for can be an exciting opportunity. An Employee Share Scheme (ESS) can allow you to participate in the future growth of your employer and potentially build wealth alongside your regular salary. However, accepting an ESS offer can also introduce tax obligations that are easy to underestimate, particularly when the value of your shares or rights changes significantly over time.

For Australian employees, the tax treatment of an ESS depends on factors including the type of interest you receive, the amount you pay for it and the rules governing the particular scheme. An ESS interest can include shares, stapled securities and  rights to acquire shares or stapled securities.. Broadly, where you receive an ESS interest at a discount, that discount may be included  in  your assessable income. Depending on the arrangement, it may be taxed upfront or at a later deferred taxing point.

Understanding these rules before a tax liability arises can put you in a much stronger position. Rather than treating your ESS as something separate from the rest of your finances, it is worth considering how the potential tax bill, investment exposure and eventual sale of your interests fit into your broader financial position.

When Do You Pay Tax on an Employee Share Scheme?

One of the most important questions to answer is when your ESS becomes taxable. Under a taxed-upfront scheme, the discount on an ESS interest is generally included in your assessable income in the financial year in which you acquire the interest. Under an eligible tax-deferred scheme, the tax liability is instead delayed until a deferred taxing point occurs.

The timing of a deferred taxing point depends on the type of ESS interest and the conditions attached to it. For interests acquired under the rules applying from 1 July 2015, the maximum deferral period can extend to 15 years. Other events may trigger taxation earlier, such as restrictions on disposal being lifted or the relevant risk of forfeiture ending. For rights, exercise and the restrictions applying to the resulting shares can also be relevant. Importantly, ceasing employment is no longer itself a deferred taxing point for employment ending on or after 1 July 2022.

This distinction matters because a tax liability may arise even if you have not received cash from selling your shares. If a substantial ESS amount becomes taxable while you continue to hold the investment, you may need to fund the resulting tax bill from savings or other sources. Planning for this possibility can help you avoid an unexpected cash-flow problem at tax time.

ESS Tax and Capital Gains Tax Are Different

Another common source of confusion is the relationship between ESS taxation and capital gains tax (CGT). They are related, but they generally deal with different stages of your investment.

The ESS rules determine how the discount, that is in connection with your employment and  associated with receiving your shares or rights, is taxed. Once the relevant ESS taxing point has occurred, a later increase or decrease in value may generally fall within the CGT regime when you eventually dispose of the investment. The cost base used for CGT purposes needs to reflect the relevant ESS tax treatment so the same economic benefit is not taxed twice.

Holding periods can therefore become important. Depending on your circumstances, an individual may be eligible for the CGT discount when a CGT asset has been held for at least 12 months, but ESS arrangements can make determining the relevant acquisition date and cost base more complicated than simply looking at the date the shares appeared in your account. Certain eligible start-up ESS arrangements also have specific concessions and rules relating to CGT.

Before selling, exercising rights or making another significant decision, it can be worthwhile understanding both the immediate ESS consequences and what that decision could mean for a future capital gain or loss.

What Should You Look for in Your ESS Documents?

Your offer documents and scheme rules are more than paperwork to file away. They can contain information that is critical to understanding both the commercial value of your ESS and its potential tax consequences.

Start by confirming what you have been offered. Is it a share, an option, a performance right or another right to acquire shares in the future? Then check the issue price, exercise price, vesting conditions, performance hurdles, disposal restrictions and leaver provisions. The documents should also help identify whether the arrangement is taxed upfront, tax deferred or intended to qualify for the start-up concession. For some tax-deferred rights, the scheme rules or offer documents need to expressly state that the scheme is tax deferred.

Keep your ESS statements and other supporting documents as well. Employers generally have ESS reporting obligations, and the information provided can help determine what needs to be included in your tax return.

Most importantly, do not wait until you are preparing your tax return to consider the implications. If shares are vesting, restrictions are about to lift, you are considering exercising options or an exit event is approaching, reviewing the position beforehand gives you more opportunity to plan.

Plan for Your ESS as Part of Your Broader Financial Position

An Employee Share Scheme can be valuable, but its value should be considered alongside the tax obligations and investment risks that come with it. Holding a significant amount of wealth in your employer’s shares can also create concentration risk because your income and part of your investment portfolio may depend on the performance of the business.

Practical planning starts with knowing your likely taxing points and estimating potential liabilities before they arise. From there, you can consider whether you have sufficient cash available to meet the tax bill, when you may want to exercise or sell interests, and how an eventual exit fits with your wider investment and financial objectives. Keeping clear records of acquisition dates, exercise prices, market values, ESS statements and transactions can also make future tax reporting significantly easier.

Every Employee Share Scheme is different, so the appropriate tax treatment cannot be determined from the words “employee shares” or “options” alone. Your individual circumstances and the terms of the scheme are critical.
