IRB has quietly launched a stamp duty operasi and they’re checking tenancy agreements, related-party contracts, and service agreements.

If you’ve signed any agreements but didn’t send them for stamping, it’s time to act.

Why?

Because from 1 Jan 2026, self-assessment begins under the revised Stamp Act. No more waiting for IRB. You calculate, you pay — or face penalties.

But don’t wait till 2026.

Rumour says IRB is already penalising unstamped documents during visits … applying the rules retrospectively @&£)%#

Hot items in IRB’s spotlight:
• Loan from director? Stampable.
• Rental agreement with related company? Stampable.
• Group service agreement? Stampable.
• Corporate guarantee? Definitely stampable.

In the past, SME bosses saw these as “internal documents.” Not anymore.

IRB’s approach is clear: Educate first, enforce next. But once 2026 hits, you’re fully accountable. IRB won’t review your agreements … that job’s yours.

What to do now:

1. Review all agreements … tenancy, loan, service, intercompany.
2. Stamp them voluntarily if you missed out earlier.
3. Talk to your tax agent before IRB talks to you.

Stamped agreements = peace of mind. Unstamped = penalty + risk in court.

Final reminder:
Have you stamped your agreement?
If you’re not sure — better check now than pay.
