Dual-listed shares offer global investors better access to markets and increased trading flexibility. But they also carry hidden tax risks. One of the biggest is withholding tax leakage, which happens when the same dividend is taxed at different rates depending on the listing location. Many investors do not realise how much dividend tax they lose this way, or that they may be able to reclaim it.
This article explains how dual listings affect withholding tax, why tax leakage happens, and how investors can recover lost income through careful planning and action.
What Are Dual-Listed Shares?
A dual-listed company (DLC) is listed on two separate stock exchanges, often in different countries. The company acts as one business, but each listing is legally distinct. For example, BHP is listed in both the UK and Australia.
These structures give investors more ways to trade, but they also expose them to different withholding tax rules. Although the dividend comes from the same company, each country can apply its own WHT rate. That difference can reduce returns.
How Withholding Tax Works Across Listings
Withholding tax is charged by the country where the dividend is paid. If a share is dual-listed, each country may apply a different WHT rate to foreign investors. For example, an investor who holds shares in Australia may pay 30% in dividend tax, while the same shares listed in the UK may only be taxed at 15% due to a treaty.
These differences create tax leakage. The same investment can result in very different outcomes depending on which listing the investor chooses.
Why Tax Leakage Happens in Dual-Listed Shares
Many investors do not know that listing choice affects their tax bill. Even when a double tax treaty allows a lower rate, investors often fail to file the required paperwork. As a result, the higher rate applies.
Some custodians and brokers also apply default WHT rates without checking whether treaty benefits apply. This is common when shares are held in pooled accounts, where the beneficial owner is not clearly identified.
Timing adds another challenge. Dividends may be paid at different times on each exchange, causing confusion and delays. Investors may struggle to track which listing the dividend came from.
Even when investors notice an overcharge, claiming a refund is not easy. Each country has its own rules, forms, and deadlines. The process is often slow, manual, and filled with barriers. Many investors give up before reclaiming what they are owed.
Foreign Investors Face Greater Exposure
Foreign investors, especially pension funds and asset managers, are more likely to lose money through tax leakage. Even a small difference in withholding tax can lead to large losses over time. Many investors do not check whether the right rate was applied or track what they could have reclaimed.
In dual-listed structures, it is even harder to tell which listing paid the dividend. If records are not clear, investors might not even realise they have been overcharged. Once the reclaim window closes, the tax is gone for good.
Tax Treaties Can Help—If Used Properly
Most countries have tax treaties that cap how much withholding tax they can charge on dividends paid to foreign investors. These treaties often reduce the rate from 30% to 15% or lower.
But to get the lower rate, investors must take action. This usually means submitting forms, showing proof of tax residence, and confirming that they are the true owner of the shares. If this paperwork is not filed, the full rate applies.
Dual-listed shares make the process harder. A dividend paid from South Africa may be taxed differently than the same dividend paid from the UK. Unless investors file documents in both countries, they may overpay.
How to Reduce Withholding Tax Losses
Investors should check their holdings and see if they own dual-listed shares. Comparing WHT rates in each country helps them choose the more tax-friendly listing.
They should also work with custodians or tax recovery experts who can apply relief at source, so the lower treaty rate is used from the start. If too much tax was paid, investors need to file a WHT reclaim as soon as possible.
Keeping tax forms up to date, using clear records, and automating dividend tracking all make the process easier and more accurate.
Additional Insight
Before buying dual-listed shares, investors should check the withholding tax rates and treaty benefits in each country. This means looking at local tax rules and the investor’s home-country treaties. Countries like South Africa and France often have more complex rules or higher default rates, which make dividend tax leakage more likely. Relief-at-source is more common for large institutions, but retail investors can still benefit—especially if their broker supports tax documentation. Working with a withholding tax specialist early on helps avoid overpayment and ensures investors get the most from their global investments.
