(Tax Update) Malaysia Stamp Duty Overhaul : Self-Assessment and Higher Penalties Part 6

01“Eh... How Would LHDN Know?” — The Self-Assessment Era Is Here
Dear Clients,
Let me share with you a very normal day at our office.
A SME boss called me — voice low, a bit nervous — and asked:
“Eh... if I don’t prepare employment contracts, how would LHDN know?”
“What if I collect rental but don’t prepare or stamp tenancy agreement?”
“I lent RM200k to my brother’s company. No agreement... can or not?”
I laughed and replied,
“Bro, IRB officers don’t live on trees anymore.”
We both laughed. But I wasn’t joking.
02What is Self-Assessment?
In Malaysia, we’ve been under the Self-Assessment System (SAS) for over 25 years — for both individuals and companies.
Starting 2025, this concept now extends to Stamp Duty too.
What does that mean?
Simple:
You’re in charge.
Not IRB.
Not your secretary.
Not your tax agent.
You are expected to:
- compute your own tax
- claim correct reliefs and deductions
- file the return
- pay your tax
- and now — stamp your documents on time
Even if no one asks.
Even if no one checks (yet).
That’s the self-assessment spirit.
03How It Works (For Individuals)
Here’s a quick breakdown:
- Calculate Income – Total up all your income for the year
- Apply Deductions – Minus your reliefs, expenses, rebates
- Compute Tax – Based on the latest rates
- File Return – BE for employment, B for business
- Pay Tax – Before deadline
Under SAS, once you file, that’s your final assessment.
If IRB audits and finds a mistake?
That’s when the headache starts.
04Stamp Duty: Self-Assess Starting 2025
Same rule now applies to documents:
- Sign employment contract → Stamp within 30 days
- Sign tenancy agreement → Assess and stamp
- Lend money to related party → Agreement must be stamped
No letter will come.
No warning. If you miss it, penalty applies.
05Big Data + AI = No More Guessing
IRB no longer need to “check drawer.”
They just check the system.
They match your:
- bank info
- e-invoice data
- CP204 filing
- related party transactions
If numbers don’t match — red flag.
Audit will come.
06E-Invoice Will Change the Game
This is not future talk — it’s already here.
With e-Invoicing, all your sales, purchases, and payments go live into LHDN’s system.
No more:
- under-declared income
- fake documents
- backdated tenancy
- “tutup mata” on director advances
Everything is digitally traceable.
Self-assessment is no longer just trust — it’s backed by tech.
07Voluntary Compliance = Your Best Insurance
In this new era:
- You keep documents for 7 years
- You act before LHDN asks
- You don’t say “I didn’t know” in 2025
Because LHDN already knows.
