How to Submit Form B via MyTax in Malaysia

For many Malaysian employees, salary is not their only source of income. They may run online businesses, freelance, or earn commission. When this happens, they are usually required to file Form B instead of the usual Form BE.

As HR or an employer, you don’t file Form B on behalf of staff, but you can guide them so they stay compliant and avoid penalties.

What is Form B?

Form B is the income tax return form for individuals with business income in Malaysia. Employees need to use Form B (not Form BE) if they:

Run a side business as a sole proprietor
Work as a freelancer or gig worker (writer, designer, rider, online seller, etc.)
Earn significant commission income (insurance agents, property agents, etc.)
Are a partner in a partnership – the partnership files Form P, but each partner still files Form B

Form B is used to declare:

All income (business, salary, rental, commissions, etc.)
Business expenses
Tax reliefs and rebates

Submission today is mainly done online through MyTax e-Filing, which is faster and more accurate than manual forms.

What You Need Before Submitting Form B

Before logging into MyTax, it helps to prepare all documents first so the filing process is smooth. Ask employees (or yourself, if you are the taxpayer) to prepare:

MyTax Login

Registered account at mytax.hasil.gov.my (IC + password).

Business Documents

Profit & Loss statement for the year
Business registration details (SSM)
Bank statements, invoices, and receipts (for reference)

Supporting Documents for Tax Reliefs

EPF/SOCSO, insurance, lifestyle relief, donations, etc.

CP500 Instalment Information (If Any)

Amounts already paid through CP500 so they can be credited correctly.

Step-by-Step: How to Submit Form B via MyTax

Form B looks long, but MyTax guides you section by section. Here is the process in simple steps that HR can share with employees.

Step 1: Log In to MyTax

Go to mytax.hasil.gov.my.
Log in using MyKad / identification number and password.
First-time users must register for MyTax before they can use e-Filing.

Step 2: Access e-Filing

On the main page, click e-Filing.
Select e-Form (e-Borang).
Choose Form B / e-B for the correct Year of Assessment (YA).

Step 3: Fill In Personal Details

Check that name, IC number, address, email, and phone number are correct.
Update any changes (for example, new address or marital status).

Step 4: Declare Business Income

Go to the business income section.
Enter:
- Gross income from business or freelance work
- Allowable business expenses (rent, utilities, marketing, transport, etc.)
The system will calculate net profit or loss based on the figures, which should match the Profit & Loss statement.

Step 5: Declare Other Income (If Any)

If the individual also has other income, they must declare it here, for example:

Employment income (salary)
Rental income
Dividends or interest
Commission not already included in business income

This gives LHDN a full picture of total income for the year.

Step 6: Input Tax Reliefs & Rebates

Go to the relief and rebate section.
Enter eligible items such as:
- EPF and life insurance
- SOCSO/EIS
- Lifestyle relief (books, gadgets, internet)
- Medical expenses for self or parents
- Approved donations or zakat
These reliefs help reduce chargeable income and the final tax amount.

Step 7: Review the Tax Summary

At the Summary page, MyTax will automatically calculate:
- Total income
- Total reliefs
- Tax payable or tax refund
- CP500 instalments already paid (if applicable)
Carefully review the numbers. If something looks wrong, go back and edit the relevant sections.

Step 8: Submit Form B

When everything is correct, click Sign and Submit.
Enter IC number and password to sign the declaration.
After successful submission, download and save the acknowledgement slip (PDF). This is proof of filing and often needed for loan applications or future reference.

Step 9: Make Payment (If Tax Is Payable)

If there is tax payable, MyTax will show the amount due.
Pay using FPX or other available methods directly from the portal or later via LHDN’s payment channels.
Save the payment receipt for your records.

Tips for a Smooth Form B Submission

A few small habits can help your employees file Form B smoothly and avoid unnecessary stress.

Practical tips you can share as HR:

Prepare Documents Early

Ask staff to keep a simple folder for income and expense records throughout the year.

Don't Wait Until the Deadline

For recent YA references, manual Form B deadlines are around 30 June, and e-Filing deadlines are around mid-July. Filing early avoids slow systems and last-minute mistakes.

Check Figures Carefully

Remind staff to double-check income, expenses, and reliefs before submitting. Errors can trigger queries or amendments later.

Keep Copies of Everything

Encourage employees to save their acknowledgement slip and key working sheets. This helps if LHDN requests clarification.

FAQs

Do I need to submit Form B online?

Today, e-Filing via MyTax is the preferred method. It is faster, more secure, and reduces calculation errors. Manual filing is still possible, but MyTax is strongly encouraged.

When is the deadline for Form B?

In recent years, for Year of Assessment 2024, the deadlines are:

Manual submission: 30 June
e-Filing (MyTax): 15 July

Future years are usually similar, but HR should always check LHDN’s latest deadline announcement for the correct year.

What happens after I submit Form B?

After submission:

MyTax generates an acknowledgement slip confirming receipt.
LHDN reviews the information and will accept it as filed unless they find issues.
If there is tax payable, the employee must pay by the due date; if there is overpayment, LHDN may issue a refund to the bank account provided.

Can I edit Form B after submitting?

Yes, minor corrections may be done through e-Amendment within a limited time after submission, or by contacting LHDN for further guidance.

Do I still need to submit Form B if my business made zero profit?

Yes. If an individual is registered and has business activity, they generally still need to file Form B, even if the business made a loss or zero profit. They can report the loss and any eligible reliefs. Non-filing can still lead to penalties.
