3 Ways to Fund Your RSU Tax Bill Before the ATO Comes Knocking

Receiving company shares is a great moment. It is a big part of your pay package. But a share vest often comes with a tax bill. Many people are surprised by this. You need to plan for it. If you don’t, you might have to sell shares at a bad time. You could face cash flow problems. This guide will explain the process. You will learn three clear ways to fund your tax bill. This helps you keep more of your shares for the future.

Shares are not like cash in your bank. When they vest, the government sees it as income. This means you owe tax. The tax amount is based on the value of the shares on the day they vest. You pay this at your normal income tax rate. It is important to know this number first. Then you can make a smart plan.

Step 1: calculate your full tax liability

Your first job is to figure out how much tax you will owe. You cannot plan without this number.

Find your marginal tax rate. This is the tax rate you pay on your highest dollar of income. It includes your salary and the value of the vested shares. Your total income for the year decides this rate.

Know the value at vest. The tax office uses the market value of your shares on the day they vest. This value is your taxable income from the shares. Multiply the number of shares by their price on that day. This gives you the total amount added to your income.

Calculate the tax. Apply your marginal tax rate to the value of the vested shares. This shows your estimated tax bill. Remember, this is just an estimate. Always talk to a tax professional for your exact numbers. They can help you with offsets or deductions.

Step 2: plan how to fund the tax bill

Once you know your tax bill, you need a plan to pay it. You have three main options. Each option has pros and cons. Your choice depends on your cash, your goals, and your view on the share price.

Option 1: sell shares at vest

This is the simplest method. You sell some of your shares right when they vest. You use the cash from that sale to pay the tax.

• How it works: When the shares vest, you immediately sell enough to cover your tax bill. The number of shares you keep is lower, but you have no tax debt.
• The tax rule: If you sell within 30 days of vesting, you are taxed on the sale price and there is no separate capital gain. Your cost base equals the market value at vest.
• Pros: It is simple and instant. You do not need to find cash from elsewhere. There is no loan or interest to worry about.
• Cons: You reduce your shareholding right away. You might sell if the share price is low. You miss out if the share price goes up later.

This option is good if you want a clean process. It works if you don’t have other savings to use.

Option 2: use your savings

This option lets you keep all your vested shares. You pay the tax bill with money you already have saved.

• How it works: You use cash from a savings account or an offset account. You pay the tax bill when it arrives. Your shares stay in your investment account.
• Important rule: You must have the cash ready. Do not spend it on something else. The tax bill will come, often months after the vest. You need to be sure the money is still there.
• Pros: You keep 100% of your vested shares. Your investment grows if the share price rises. You avoid selling at a potentially bad time.
• Cons: It ties up your cash. That money cannot be used for other goals. You lose the interest you might earn on that savings.

This is a strong choice if you have spare cash. It lets your shares grow without being sold.

Option 3: use home equity

This option uses the value you have built in your home. It is for people who own property. You set up a loan facility against your home’s equity.

• How it works: You arrange a line of credit with your bank before the shares vest. Once the tax bill is due, you draw money from this line of credit. You use that loan to pay the tax.
• Important rule: You must set this up in advance. Banks take time to approve these loans. Do not wait until the tax bill arrives.
• Pros: You keep all your vested shares. You do not touch your personal savings. It can be a low-cost way to borrow money.
• Cons: You take on debt. You must pay interest on the borrowed money. This adds to your costs. It also adds risk if you cannot repay the loan.

This option is good if you have home equity. It works if you believe your shares will grow in value faster than the loan’s interest rate.

Comparing your three funding options

It’s helpful to see these options side by side. The table below shows the key points.

Option	Key Action	You Keep…	Main Risk
Sell Shares at Vest	Sell shares immediately.	Fewer shares. No debt.	Selling when share price is low.
Use Your Savings	Pay with existing cash.	All shares. Cash is locked up.	Tying up your savings for months.
Use Home Equity	Pay with a secured loan.	All shares. Your savings.	Taking on debt and paying interest.

How to choose? Think about your own situation. Ask yourself these questions.

• Do I have spare cash I won’t need soon? If yes, Option 2 (Use Savings) is strong.
• Do I believe my company’s share price will rise a lot? If yes, avoid Option 1 (Sell Shares). Try to keep all shares using Options 2 or 3.
• Do I own a home with available equity? If yes, Option 3 is possible. Talk to your bank early.
• Do I want the simplest path with no debt? If yes, Option 1 is the easiest.

Your action plan

Now you know the steps. Here is what to do next.

1. Talk to a professional. Speak with your accountant or tax adviser. Get them to calculate your exact tax liability. This is the most important step.
2. Check the vest date. Know exactly when your shares will vest. Mark it on your calendar.
3. Review your finances. Look at your savings. Check your home equity. See which funding option fits your life.
4. Set up your choice. If you choose to use savings, move the cash aside. If you choose a line of credit, contact your bank now. Do not wait.
