Malaysia's New Stamp Duty Self-Assessment System: What Businesses Need to Know

Could Your Everyday Business Agreements Be Subject to Stamp Duty?

Many businesses assume that only formal contracts attract stamp duty. In fact, the substance of a document matters more than its title. If a written document creates legally binding rights or obligations, it may be regarded as an "instrument" under the Stamp Act 1949 and could be subject to stamp duty—regardless of whether it is called an MOU, Letter, Service Agreement, or Addendum.

With the introduction of the Stamp Duty Self-Assessment System (SDSAS) from 1 January 2026, businesses are responsible for determining whether stamp duty applies, calculating the duty payable, and ensuring timely payment.

Could Your Business Agreements Be Subject to Stamp Duty?

Many businesses execute dozens—sometimes hundreds—of agreements every year. The following are some of the more common documents that may attract stamp duty.

Business Area	Examples of Agreements
Sales and Operations	Service Agreements, Consultancy Agreements, Maintenance Contracts, Technical Services Agreements, Outsourcing Agreements, Distribution Agreements, Agency Agreements
Procurement and  Projects	Supply Agreements, Supply & Installation Contracts, Construction Contracts, Subcontract Agreements, EPC Contracts
Property	Tenancy Agreements, Lease Agreements, Equipment Rental Agreements
Corporate	Share Subscription Agreements, Shareholders' Agreements, Joint Venture Agreements, Business Sale Agreements, Asset Purchase Agreements
Finance	Loan Agreements, Guarantees, Security Documents, Debentures, Indemnities
Human Resources	Employment Contracts, Fixed-term Contracts, Renewal Agreements, Secondment Agreements, Internship Agreements*
Intellectual Property	Licence Agreements, Technology Transfer Agreements, IP Assignment Agreements
Other Legal Documents	Settlement Agreements, Franchise Agreements, Letters of Appointment, Addendums and Contract Variations

Whether a document is dutiable depends on its legal effect and the applicable provisions of the Stamp Act 1949.

It's Not Just Agreements...

Businesses are often surprised that documents with relatively simple titles may also require stamping, such as:

• Letters of Appointment

• Contract Addendums

• Variation Agreements

• Renewal Letters

• Binding Memoranda of Understanding (MOUs)

• Certain Offer Letters

• Side Letters

• Emails that create enforceable rights or obligations

The guiding principle is simple:

A useful rule of thumb is this: if a document creates, varies or records legally enforceable rights or obligations, it should be reviewed to determine whether stamp duty and exemptions apply.

Conduct a Stamp Duty Health Check

With SDSAS, businesses should review their agreements, identify dutiable instruments, and implement robust stamp duty procedures. As LHDN shifts towards self-assessment, stamp duty is expected to become an increasing area of audit focus.
