What is BIR Form 1601C
Form 1601C, also known as the Monthly Remittance Return of Income Taxes Withheld on Compensation, is a tax form used by employers to report and remit the income tax withheld from their employees’ salaries each month. Every time an employer deducts tax from an employee’s pay, that amount must be declared to the BIR through this form.

Frequently Asked Questions
You report total compensation paid to employees, calculate how much tax was withheld for that month, and remit the correct amount to BIR
Failure to timely file or pay can incur a 25% surcharge, 20% interest per annum, and possible compromise penalties, depending on circumstances
Yes. As long as you’re paying compensation and withholding income tax from that employee’s salary, you’re required to file 1601-C every month, even if it’s just for one person.
Yes, but if you’re not withholding tax because all your employees are minimum wage earners, you may still be required to file a “No Withholding” or “Zero Return.” However, if there are no compensation payments at all (e.g., closed operations), you may be exempt for that period. It’s best to consult your RDO.
Yes. You can file an amended return if you made an error in the original form (e.g., wrong amount withheld or paid). Just make sure to indicate that it is an “Amended Return” when submitting in Taxumo.
The monthly 1601-C is the basis for how much tax you’ve remitted for your employees. At year-end, you issue each employee a Form 2316, which shows how much income they earned and how much tax was withheld and remitted to the BIR on their behalf.
