Malaysia Tax Filing Guide for Business Owners

By Axecta Management Services, Kuala Lumpur · Last verified: 29 October 2026

Start with your structure, not the form

Malaysian tax is not one return for everyone. The Inland Revenue Board (LHDN, also branded HASiL) separates companies, individuals who run a business, and partnerships, and each has its own form, rate table and timeline. A first-time business owner often searches “how to file tax” and lands on a guide written for employees, which leads to the wrong form. The first step is to write down what you are, because that decides everything that follows.

A single business can have more than one row. A Sdn Bhd with staff files Form C and Form E. A sole proprietor with employees files Form B and Form E. The sections below take each in turn.

What LHDN publishes each year

LHDN’s Return Form Filing Programme for 2026 (published 30 December 2025, updated 1 April 2026) is the document to bookmark. As at October 2026 it lists:

The programme also says taxpayers and employers must use e-Filing at MyTax, and that tax agents file through the Tax Agent e-Filing system. Mandatory e-Filing started for companies in year of assessment 2014, for LLPs in 2021, and for individuals and partnerships in year of assessment 2023. Paper filing is no longer the normal route.

How a company’s Form C date works

LHDN’s company tax page and taxpayer responsibilities page say a company must furnish its return within 7 months after the close of its accounting period. The date therefore moves with your financial year end. A company with a 31 December year end has a different date from one that closes on 30 June. The programme’s grace date also moves by month, so work out your own date rather than copying a competitor’s. The detail is covered in Form C filing deadline and common mistakes and when corporate tax is payable.

Step by step: the annual filing cycle

1. Register with LHDN. Individuals who run a business, partnerships, LLPs, employers and companies not yet registered need an income tax reference number through e-Daftar. LHDN’s page says to expect it within 3 working days after completing the online application. For a business owner, the documents include the SSM registration certificate (and a list of partners for a partnership).
2. Keep monthly books. Tax is only as accurate as the accounts. See monthly bookkeeping vs annual accounts.
3. Close the year and prepare accounts. Profit and loss, balance sheet and supporting schedules.
4. Prepare the tax computation. Adjust accounting profit to adjusted income, deduct capital allowances, and arrive at chargeable income. See which business expenses are deductible.
5. Estimate and pay during the year. Companies submit a CP204 estimate and pay monthly instalments; see CP204 estimated tax.
6. Log in to MyTax and file. Individuals logging in for the first time without a digital certificate are guided through registering one using e-CP55D (web) or e-KYC (face identification), according to LHDN’s income declaration page.
7. Pay any balance. LHDN’s individual FAQ lists the ByrHasil online application, LHDN collection agents, and overseas transfer for payers abroad, and says to keep the receipt.
8. File the employer return if you employ staff.
9. Keep records. See tax record-keeping requirements.

Employer filings run on a separate clock

If you employ staff you file Form E for the previous year by 31 March, with a one month e-Filing grace period in the 2026 programme. The programme’s guide notes say a Form E is only complete if the CP8D listing is submitted by the due date. Sole proprietorships, partnerships, Hindu joint families and deceased persons’ estates that have no employees are exempted from the CP8D. Dormant companies, LLPs, trust bodies and co-operative societies must still file Form E and CP8D. Dormant means never having started operations, or having ceased business. See employer payroll obligations and PCB/MTD explained.

What late or wrong filing can cost

LHDN’s offences, fines and penalties page lists these as at October 2026:

The programme’s guide notes add that for returns other than Form E and Form P, LHDN can take action under section 112(1) or impose a penalty under section 112(3). For Form E and Form P the action is under section 120(1). Take the figures as a guide to seriousness, not a quote of what you would pay, because the outcome depends on the case.

Illustrative scenario

This is an illustration, not a client case. A trading Sdn Bhd closes its books on 31 December. Under the 7 month rule its Form C is due by 31 July of the following year. It has paid-up capital within RM2.5 million, gross business income within RM50 million and, assume, meets the other conditions in PR 8/2025. If its chargeable income is RM700,000, LHDN’s published YA 2023 to 2024 rates (15% on the first RM150,000, 17% on RM150,001 to RM600,000, 24% on the rest, per the company tax rate page) give:

The CP204 instalments over the year should approximate this, and the Form C reconciles the difference. The rate page was last updated 25 June 2026 and lists bands only up to YA 2023 to 2024, so check it for the year you are filing. For the rate rules see Malaysia corporate tax rate for Sdn Bhd.

What this means for different owners

Sole proprietor

Your business profit is added to any other income and taxed through Form B. LHDN’s individual FAQ says an individual who runs a business must register for a tax number even if the business makes a loss. Business income returns fall due on 30 June rather than 30 April.

Sdn Bhd

The company is a separate taxpayer. The directors are responsible for making sure Form C, the CP204 and, where there are staff, Form E are filed. LHDN’s programme says dormant companies must still furnish Form E and CP8D, so do not assume that no trading means no filing.

Foreign-owned company

Foreign ownership affects eligibility for the lower SME rates under PR 8/2025, which adds a 20% foreign ownership test from YA 2024. Confirm the ruling’s conditions before relying on the 15% or 17% bands.

Partnership

The partnership files Form P; each partner declares a share in their own return. See partnership tax and Form P.

Common mistakes

• Filing the wrong form. A business owner using Form BE (no business) when Form B applies.
• Treating the grace period as the deadline. It is a safety margin, and it does not apply to payment of the balance for Form E or Form P.
• Mixing personal and business spending. It pollutes the computation and weakens deductions.
• Skipping nil or dormant filings. A company with no trade still has employer-return duties under LHDN’s programme, and its other returns should be confirmed, not assumed.
• Late accounts. The return waits for finished accounts, so accounts delayed past the year end often mean a rushed return.
• No CP204 revision. See CP204 estimated tax for the revision windows.
• No record trail. Missing invoices cost deductions.

How Axecta helps

Axecta’s tax team prepares the computation, files through MyTax and handles LHDN follow-up. We give each client a filing calendar showing every date for the year, including Form C, CP204 revisions and Form E. Where a client is still on shoebox bookkeeping, we start with the accounts, because the return depends on them. See our tax compliance and filing service.

2. Check you have an LHDN tax number and MyTax access.
3. Open the current Return Form Filing Programme and mark your dates.
4. Agree who prepares the accounts and the computation.
