I get a lot of queries on how to compute Philippine Withholding Tax on Compensation. I have been intending to make a post about it, but taking screenshots of the withholding tax table, while explaining the computation at the same time may be difficult for the readers to comprehend. Finally, you can now compute your withholding tax by using the BIR’s Withholding Tax Calculator. 
Restrictions/Limitations on the use of BIR’s Withholding Tax Calculator
- The application is not downloadable.
- The application is simply an automated computation of the withholding tax due based only on the information entered into by the user in the applicable boxes. Accordingly, the withholding tax due computed by the calculator cannot be used as basis of complaints of employees against their employers.
- No validation process is being performed on the following information:
- Basic Salary/Statutory Minimum Wage Earner (whether or not the basic salary is more than or less than the statutory minimum wage in the National Capital Region or in other regions)
- De Minimis Benefits (whether or not the total de minimis benefits received by the employee is more than or less than the total threshold)
- The Cumulative Average Method in computing withholding taxes (where the total supplementary compensation is equal or greater than the total regular compensation) cannot be accommodated in the calculator.

Wow, this is useful information. I've been working for decades and I never bothered knowing how to compute withholding tax. This calculator would make it easier. Thanks for sharing!
Taxes.. the government is taking too much taxes from us wage earners. I hope a new law will be passed and approved to lessen our taxes.. The bonus is already the first step I hope the monthly salary as well.
This is good. Sometimes, you just rely on HR/admin to do the job in computing the taxes. You can never check if they are correct unless you know how to compute it yourself.
