Swingvy uses a computerized method to calculate the employee's MTD (Month Tax Deduction). This method is equivalent to the e-PCB by IRB.     **Note:** PCB stands for Potongan Cukai Bulanan in the Malaysian national language. The acronym is popularly known for monthly tax deductions among many Malaysians.   A couple of values are needed to obtain an accurate PCB result.   Before starting the computation of the employee's MTD, we must identify the employee's status and some other information below:   - Residential Status - Marital Status - Disable Individual - Spouse Working - Disable Spouse - No of Children - Past month remuneration - If the employee has worked before in the current year - Past month EPF contribution - Maximum RM4,000 relief per year - Past month MTD amount - If any - Past month tax relief deduction - If any - Current month remuneration - Current month EPF contribution - Current month tax relief deduction Below is an example of PCB computation with a simulation data:    ![](https://help.swingvy.com/hubfs/image-png-Jun-03-2021-01-43-08-35-AM.png)   First, calculate the P-value from the above values   **P-Value** P-value is the total chargeable income for a year   ![](https://d2x3xhvgiqkx42.cloudfront.net/5d53f37f-36d4-4148-a7ef-a6f707c9e2c9/1a446691-50d0-4b24-989b-92269b27a4c7/2019/08/09/37cddf9a-abb9-419d-889e-60bcbe1518f8/334a736f-b197-4fb0-a53d-74b324c5ee47.png)   From the P-value, we are able to determine the percentage of tax based on the first chargeable income   **Table of the tax rate** ![](https://help.swingvy.com/hubfs/image-png-Jun-21-2023-04-16-33-7509-AM.png) ![](https://help.swingvy.com/hubfs/image-png-Jun-21-2023-04-40-56-5835-AM.png) The MTD amount will be calculated with the formula defined by the IRB. #### **Verify MTD results with Swingvy's one-click verification** To verify the PCB result manually can be a very hassle task, the result might also turn out vary if the amount used during the verification is not consistent.
