CP37 Form Malaysia: Withholding Tax on Overseas Payments

1. What Is the CP37 Form?

Quick Answer: CP37 is LHDN’s “Account of Deduction from Royalty and Interest to a Non-Resident Person” under section 109 of the Income Tax Act 1967. The Malaysian payer deducts tax from the payment, sends LHDN the form and pays the tax within one month. Royalty is taxed at 10% and interest at 15%, unless a tax treaty sets a lower rate.

The key idea is simple. The overseas supplier owes Malaysian tax on income it earns from Malaysia, but LHDN cannot easily chase a company in London or Singapore. So the law makes the Malaysian payer collect it. The official CP37 form (Pin 1/2024) quotes section 109 directly: the payer must deduct the tax and pay it “within one month after paying or crediting” the royalty or interest, whether or not it was actually deducted.

Three points follow for a marketing budget:

• The duty sits with you, not the supplier. If you pay the full invoice and forget the tax, LHDN collects it from your business.
• “Paid or credited” starts the clock. Booking the invoice as payable in your accounts can count, not just the bank transfer.
• One form per payee. LHDN’s notes ask for a separate CP37 for each non-resident person you pay.

Whether the cost is deductible on your own return is a separate question, covered in our guide on whether advertising is tax deductible in Malaysia. This post is about the withholding step that protects that deduction.

2. CP37 vs CP37D vs CP37F: Which Form Do You Need?

Quick Answer: The form depends on the type of payment, not the supplier. Use CP37 for royalty and interest, CP37D for special classes of income such as in-Malaysia services and equipment rental, CP37F for other paragraph 4(f) income, and CP37A for contract work done in Malaysia. Most marketing payments land on CP37, CP37D or CP37F.

LHDN’s withholding tax page (last updated 5 October 2026) lists every form. These are the ones a marketing or website budget is most likely to touch.

Two limits matter. First, LHDN says special classes covering services and advice “shall only apply to the amount attributable to services which are performed in Malaysia”. Equipment rental has no such limit. Second, a tax treaty can lower the rate, but only if you hold written proof from the foreign tax authority that the supplier is resident there.

3. Which Overseas Marketing Payments Need Withholding Tax?

Quick Answer: Licences to use someone’s creative work, advice or services performed physically in Malaysia, and rental of moveable equipment are the usual triggers. Pure remote work done entirely abroad often falls outside the special classes. Ad platforms, software subscriptions and freelancers each have their own quirks, so test each payment rather than assuming.

Each grey area has its own deep dive. See our guides to withholding tax on marketing SaaS like Canva and Semrush, overseas freelancers on Fiverr and Upwork, paying overseas influencers and withholding tax on Google and Facebook ads. Local agents and affiliates are a domestic matter under a different rule, covered in Section 107D for affiliates and agents.

4. How Do You Calculate CP37 Withholding Tax? A Worked Example

Quick Answer: Multiply the gross payment by the rate, pay the supplier the balance and send the tax to LHDN within a month. If your contract promises the supplier the full amount “net of tax”, you must gross it up instead, which raises your real cost by about 11% at a 10% rate.

Picture Brand Z Sdn Bhd licensing a foreign illustrator’s character for a 12-month campaign. The fee is RM20,000 and the licence is a royalty. Figures are illustrative.

If Brand Z pays on 15 March 2027, the form and the RM2,000 are due by 15 April 2027. Many overseas creators also ask for a self-billed e-invoice and proof of tax paid, so they can claim credit at home. Our guide to self-billed e-invoices for overseas ad payments covers that document. Separately, buying services from abroad can also trigger 8% imported services tax, which is a different tax with its own return.

5. How Do You Submit CP37 and Pay Through e-WHT?

Quick Answer: Log in to MyTax, open e-WHT, pick the right form, enter payer, payee and payment details, then submit to get a bill number. Pay with that bill number through FPX on ByrHASiL or selected banks within one month of paying the supplier. Keep the invoice, payment proof and receipt together.

LHDN still accepts some manual routes, but it encourages online filing, and e-WHT keeps the form and payment linked. Use this checklist for each overseas payment:

1. Classify the payment. Royalty, special class, 4(f) income or contract payment, using the table in Section 2.
2. Check for a treaty rate. Get the supplier’s certificate of residence from its home tax authority before applying any lower rate.
3. Deduct at payout. Pay the supplier the net amount and record the gross, the tax and the net.
4. Submit the form on e-WHT. Log in to MyTax with your company role, complete the CP37, CP37D or CP37F and note the bill number. Use one form per non-resident payee.
5. Pay within one month. Pay by bill number through ByrHASiL (FPX) or a selected bank. Companies without a Malaysian FPX bank can use an e-TT virtual account number instead.
6. File the evidence. Keep the supplier invoice, proof of payment, the e-WHT slip and any treaty certificate for future reviews.

Small, frequent licences get some relief. LHDN lets you defer small-value payments under sections 109 and 109B and pay them in two batches a year, which suits teams buying stock assets every month.

6. What Happens If You Pay CP37 Late or Not at All?

Quick Answer: Late tax is increased by 10%, paid separately on Form CP147. Until the tax and the increase are paid, the whole overseas payment is disallowed as a business expense. Claiming it anyway on your return can draw an incorrect-return penalty. Paying later, with the increase, restores the deduction.

LHDN’s own example on its withholding tax page uses a RM200,000 royalty paid on 15 November 2023, with the RM20,000 tax received on 20 December 2023: the payer owed a further RM2,000. The bigger hit is usually the lost deduction, not the 10%. Here is how that plays out on our RM20,000 licence.

The most common marketing mistakes behind these numbers:

• Paying by company card. A licence bought on a card skips accounts payable, so nobody checks for withholding tax.
• Assuming “foreign” means “exempt”. Royalty and equipment rental are caught even when the supplier never visits Malaysia.
• Applying a treaty rate without a certificate. No written residence proof means the full domestic rate applies.
• Mixing up taxes. Withholding tax, digital service tax on foreign software and SST on local invoices are three separate checks.

If you have missed a payment, pay the tax and the increase quickly; LHDN takes withholding tax appeals and remission requests online through MyTax. Your agent can also advise on related timing questions, such as when SST is due on agency invoices.

7. How Can Marketing Teams Make CP37 Routine?

Quick Answer: Flag overseas suppliers before the first payment, not at year end. Collect the supplier’s country, entity type and treaty certificate at onboarding, agree the tax clause in the quote, and route every overseas marketing invoice through finance so the one-month clock is never missed.

A short supplier checklist does most of the work:

• Onboarding form. Ask every new supplier for legal name, country of tax residence, Malaysian tax number if any, and what exactly they deliver.
• Tax clause in every quote. State whether fees are inclusive of Malaysian withholding tax, so the gross-up surprise never happens.
• One owner for MyTax. The person with company access to e-WHT should see every overseas invoice the day it is approved.
• Prefer local where it makes sense. Work bought from a Malaysian supplier carries none of these withholding steps, though SST on software and IT services may still apply.

Sole proprietors are not off the hook: the payer duty applies to any business that claims the expense, and the deduction on Form B marketing claims depends on it too. ZenWeb helps on the marketing side, with clear local quotes, Malaysian invoices and e-invoice-ready websites, while your tax agent handles the filing. Our digital marketing services keep campaigns, creative and reporting under one Malaysian roof.

8. Conclusion: Know Your Form Before You Pay Overseas

CP37 and its sister forms are simple once you know the pattern. Classify the payment, apply the rate, file on e-WHT and pay within a month. Royalty, in-Malaysia services and equipment rental are the usual marketing triggers; fully remote work abroad often is not. As at October 2026 the rates and the one-month rule are stable, but Budget 2027 is tabled on 9 October 2026, so check LHDN’s notices for any change.

9. Frequently Asked Questions

1. What is the CP37 form used for?

CP37 is the LHDN form for withholding tax on royalty and interest paid to a non-resident under section 109 of the Income Tax Act 1967. The Malaysian payer deducts 10% from royalty or 15% from interest, unless a treaty rate applies, and pays it within one month.

2. What is the difference between CP37 and CP37D?

CP37 covers royalty and interest. CP37D covers special classes of income under section 109B, such as advice or services performed in Malaysia and rent for moveable property. Both carry a 10% domestic rate for these payments.

3. When must CP37 withholding tax be paid?

Within one month after the payment is paid or credited to the non-resident. Late payment adds a 10% increase, paid separately on Form CP147, and the expense is disallowed until the tax and increase are paid.

4. Do I need CP37 when paying an overseas freelancer?

It depends on what you buy. A licence to use their work can be royalty, taxed at 10%. Services done fully outside Malaysia often fall outside the special classes, but check any licence element with a tax agent.

5. Can I submit CP37 online?

Yes. LHDN encourages filing through e-WHT on the MyTax portal, which issues a bill number. You then pay through FPX on ByrHASiL, selected banks, or an e-TT virtual account if you have no FPX bank.
