🏡💰 Can a 99-1 ownership structure legally help a couple avoid ABSD on a second property?

This is one area where property owners need to be especially careful in 2026.

A genuine 99-1 ownership arrangement is not automatically illegal. The problem arises when the ownership structure does not reflect the parties' true beneficial ownership, or when the arrangement is deliberately structured as a two-step scheme to reduce ABSD. The Court of Appeal's May 2026 decision has made this distinction much more important.

Why does this matter?

For a Singapore Citizen buying a second residential property, the current ABSD rate is 20%.

So on a $2M property:
💰 20% ABSD = $400,000

That explains why some couples have considered 99-1 structures.

But the key question isn't simply:

"Can we put the property under 99-1?"
It's:

📋 Does the ownership reflect the genuine arrangement?
💰 Who is actually contributing the purchase funds?
🏡 Who has the beneficial interest in the property?
📊 What happens if one spouse later buys another property?
⚖️ Does the entire arrangement have a legitimate commercial purpose?

IRAS has also warned that two-step "99-to-1" arrangements designed to pay ABSD only on a small share can result in the rightful stamp duty being recovered, with a 50% surcharge on the additional duty payable if tax avoidance is established.

There is a very different strategy called genuine decoupling, where an existing co-owner later transfers their share to the other owner at market value and the correct stamp duty is paid. That remains a legitimate transaction when properly structured.

📌 The lesson in 2026 is simple: 99-1 isn't a magic ABSD shortcut.

If the legal ownership, financial contribution and beneficial ownership don't genuinely line up, the potential savings can quickly become a much bigger liability.

For any decoupling or 99-1 arrangement, get proper legal and tax advice before committing to the structure.
