Simplifying Taxation for MSMEs: File your BIR Form 1601C even without an Accountant

The BIR Form 1601C is listed as one of the Bureau of Internal Revenue (BIR) tax returns in our blog post 4 Common Tax Deadlines MSMEs should remember. Now, let’s dive deeper into the details.

Understanding the tax returns can save you from potential headaches down the road. That’s why we prepared a comprehensive guide that only requires a little bit of your patience and some organized record-keeping. Remember, the more you know, the less intimidating it becomes.

What is the BIR Form 1601C?

The BIR Form 1601C also called Monthly Remittance Return of Income Taxes Withheld on Compensation is the tax form used to file for Withholding Tax on Compensation (WTC).

WTC is the monthly tax deductions made by employers on the salaries and wages before paying their employees. This withholding process is implemented to streamline the individual income tax collection process of the BIR. WTC is NOT a tax on your business. It is a tax imposed on the income of your employees. You, as the employer, are simply collecting it on behalf of the BIR, instead of your employees paying it directly.

How to compute the WTC?

The amount of WTC is computed per employee through the steps that follow:

Step 1. Determine the total compensation

The BIR defines the terms compensation or wages as all remunerations for services rendered by an employee to their employer. The BIR classified the compensation for the purpose of WTC into:

  • Regular Compensation – this includes the basic salary and other fixed allowances of the employee and;

  • Supplementary Compensation – this includes the following:

    1. Commission

    2. Overtime pay

    3. Fees, including directors fees

    4. Profit sharing

    5. Monetized vacation leave in excess of ten (10) days

    6. Sick leave

    7. Fringe benefits received by rank-and-file employees

    8. Hazard pay

    9. Taxable 13th month pay and other benefits

    10. Other remuneration received from an employee-employer relationships

The above basically means ALL compensation and benefits you give to your employees regardless of what you call it. List all these then proceed to Step 2.

Step 2. Determine the taxable compensation

The total compensation of your employees is not automatically taxable. You can deduct their non-taxable or exempt compensation to arrive at their taxable compensation.

Non-taxable or exempt compensation normally includes the following:

  • Employee’s share on the mandatory government contributions such as the Social Security System (SSS) contributions, Philhealth contributions and the Pag-Ibig or the Home Development and Mutual Fund (HDMF) contributions;

  • De minimis benefits;

  • 13th month pay and other benefits up to Php 90,000 in total for the year; and

  • Other non-taxable or exempt compensation as explicitly indicated in the National Internal Revenue Code (NIRC or Tax Code) and other pertinent laws.

It is also important to note that you are not required to withhold tax on compensation for employees who are minimum wage earners.

Step 3. Determine the WTC using the Withholding Tax Table

The Withholding Tax Table is provided by the BIR. The WTC from January 1, 2023 and onwards is shown below.

We’ve also prepared a printable withholding tax table; you may download it through this link.

See example below to see how to apply Steps 1 and 2, and how to use the Withholding Tax Table in Step 3.


Employee A is paid monthly and earns a basic salary of Php 25,000 per month with no other benefits. She has the following government contributions based on her monthly salary:

SSS: Php 1,125.00

Philhealth: Php 500.00

Pag-Ibig: Php 100.00

Total: Php 1,725.00

*The above amounts are taken from the contribution tables provided by SSS, Philhealth and Pag-ibig.

Let’s apply the steps above in computing for the WTC of Employee A.

Step 1 – The total compensation is her basic salary of Php 25,000 since she doesn’t have any other benefits.

Step 2 – The non-taxable compensation of Employee A is her total government contributions. Her taxable compensation is:

Php 25,000 – Php 1,725 = Php 23,275

Step 3 - Per Step 2, Employee A has a taxable compensation of Php 23,275. In the withholding tax table, Employee A falls under the compensation range of “Php 20,833 - Php 33,332”. Under this range, the withholding tax shall be Php 0.00 + 15% over Php 20, 833. So, the computation will be:

WTC = 0 + 15% * (23,275 – 20,833)

WTC = 0 + 15% * (2,442)

WTC = 0 + 366.30

WTC = 366.30

The amount you will withhold from Employee A will be Php 366.30. Her net pay is then computed as follows:

Total Compensation (Step 1) Php 25,000.00


Government Contributions ( 1,725.00)

Taxable Compensation (Step 2) 23,275.00


WTC (Step 3) ( 366.30)

Net Pay Php 22,908.70

Continue this process for the rest of your employees. You will need to consolidate their total compensation, non-taxable or exempt incomes and their withholding tax on compensation then you’re ready to file your BIR 1601C.

The BIR, in its efforts to simplify the tax calculation process, also has a Withholding Tax on Compensation Calculator, an online application tool for calculating WTC designed to assist employers and employees in accurately determining the amount that will be withheld from salaries.

In using the WTC Calculator, you will have to input the amount in the boxes that corresponds to the details of the employee’s compensation.

Let’s plot the details given in the example above. First, you will need to enter the taxable compensation of Employee A.

Always make sure to select the correct payroll period applicable to your employee. In our example, it is stated that Employee A is paid monthly.

Next, enter the non-taxable compensation.

Then, on the bottom of the calculator, you will see a “Compute” button. Just click it and the WTC will be automatically computed.

Just remember, while online calculators can be useful tools it can also have its limitations. It will only rely on the data you have provided, so you will have to double-check the data you are entering to ensure its accuracy and completeness. If you're uncertain about any aspect of the computation or if you're dealing with a complicated compensation detail of employees, it's advisable to consult a tax professional for guidance.

When should you file the BIR Form 1601C?

The BIR 1601C is filed on a monthly basis. The deadline for filing is on or before the 10th day of the following month in which the taxes were withheld. For example, the form for the month of June (showing the amount of WTC made in June) is due on or before July 10.
