A few months ago, Celine asked me to make an app she can use in computing the taxes and statutory deductions based from a specific salary. There wasn't an existing app yet for that purpose. Since it will not only benefit her (and me), but a lot more too, I decided to start developing the app. However, due to time constraints and because of the complicated processes in computing the taxes and deductions, it took a long while to develop the app.
Last week, I have finished the prototype of Salary Calculator. It is an online tool for Filipinos that they can use to compute their net pay, withholding taxes and contributions to SSS, Philhealth and PAG-IBIG. Users just need to provide their basic pays, and allowances (taxable and non-taxable allowances), as well as the rate (semi-monthly, monthly or annual). Then with just a click of the "Compute" button, the app will display the gross pay, withholding tax amount, net pay and the deductions for PAG-IBIG, SSS, and Philhealth. The withholding tax was computed based from the monthly taxable income using the BIR Revised Withholding Tax Table. The computation of the other deductions are based from PhilHealth Contribution Table, SSS Contribution Table, and Republic Act No. 9679 (for the PAG-IBIG contributions).
The app can be accessed at http://sweldongpinoy.tigcal.com and is still a work in progress. Try the app and please give comments and suggestions.
Update: The app is now called Sweldong Pinoy and is now also available on Chrome Web Store. We've also made an Android app which can now be downloaded on Google Play.
Update (December 19, 2012): The app is now at http://www.sweldongpinoy.com. The previous URLs redirect to this website now. We'll also be publishing an update to the app in connection to the increase in the PhilHealth contribution (see PhilHealth Circular 11 s. 2012 for details). For updates, you may also follow @sweldongpinoy on Twitter. Thank you very much for using the app!
Update (March 28, 2013): We already have a blog at http://blog.sweldongpinoy.com. We'll be posting news and updates about the app there.
