    hi this is gerald..,i just want to ask since i am
    earning like 16000 per month and every 5th of the
    month a commision of lets say
    in every 5th of everymonth iam earning:
    7500 (16000 month salary / 2)
    + 30000
    and my tax withheld is like 10k????isnt it unfai????
    iam working hard and yet all that is left on me is like 2/3 of what i should have????really unfair!!!!!its unjust!!!!!

  2. admin says:


    You should be using MONTHLY computation instead of SEMI-MONTHLY. By using the calculator, enter 16,000 in your basic salary and the 30,000 commission will fall under allowances-other. I assume you are still single with no dependents and the calculator will have 10,160.67 as your withholding tax.

    My sister is living in United Kingdom and their taxes goes as high as that percentage and they think it is still fair. What is NOT FAIR here in the Philippines is that we could not see where our taxes go.

  3. Useful information for BIR Withholding Tax and your post regarding for BIR looks very interesting. I always like to leave comments when I see a good looking website. Keep up the great work.

    Good day! How do we compute the tax refund for an employee who only rendered 8 months of work for the year? Your answer will be much appreciated. Thank you

  5. admin says:

    Try computing your total salary for that 8 months with Philhealth, SSS and PAGIBIG already deducted. Divide it by 8 then use the monthly computation. Your monthly tax should be around that value, assuming you have no other income for that year.

    hi this is jennie. please help me with this. the company i will be working for asked me if i wanted the tax deducted according to my tax status which is ME3 or the 15%. apparently the company is under some RA provision which allows it to deduct 15% of withholding tax. i would like to know where i would have less deductions. could you also tell me please how to compute the ME3? thank you so much in advance.

    I just wanna ask if the allowance is included on the tax also

  11. Raymond says:

    How should the withholding tax of the 13th month be computed. Specifically the amount going over P30,000? Should that amount be added to the December taxable Income? Or should it be on a separate pay slip? The computation differs on theses 2 options.

    ie: A monthly income of PhP40,000

    Should it be computed together?
    Taxable: 40,000 + 10,000(amt over 30k of 13th mnth)


    Should it be computed separately?

    Taxable: 40,000 (for December pay slip)
    Taxable: 10,000 (13th month pay slip)

    Using the calculator returns different results when done either way. Smaller for withholding tax for separate slips.


  12. admin says:

    As far as I know, 13th month is not taxable if it is below 30K. What is in excess of 30K will be taxed. The reason why it is inaccurate because the 13th month tax is calculated using the annual process and not monthly. I am sorry but we did not include annual calculation on this tool.

  13. ritzel says:

    I’d like to know if I can file a case to my employer. I’ve been working with the company for about 6 years. Every month, they deducted withholding tax on my salary but February came, I did not receive any single amount for my tax refund. I really need your reply. Thanks!

  14. admin says:

    @ritzel, what I can suggest is for you to go to BIR and ask for your ITR (Income Tax Return) and compare it with what your company is deducting from you every month. This BIR tool of ours is for us to have a value close to your tax schedule.

  15. arcee says:

    hi, am just confused and really in need of help. my previous salary was amounting to php12,000+ monthly, gross income and under contractual, so no other deductions except for the taxes which is in 10% and 3%. 10% will be the withholding tax. this situation last for almost a year and 2 months. after a while, the general accounting division notice that my salary range will supposed to be under the 2% withholding tax. i asked the assigned officer if i could make a refund on the excess 8% deducted from my salary, she told me that since tax is already remitted i can’t make a refund. i made a computation, i suppose to have a refund almost php12,000. what i’m trying to ask here is, is there any way to refund the excess tax collected from me? please, i really need an answer, 12,000 is so hard to earn.

  16. ako po ay sumasahod ng minimum 426 pesos a day,i have 2 kids.magkano po ang kailangan ko contribute sa tax

  17. admin says:


    If meron pong 22 working days in a month, your monthly income would be around Php9,372. If gagamitin natin ang calculator, mga Php21.12 lng ang babayaran mong buwis kada buwan. Ito po ay estimate lamang. Kung ang binabayaran nyo po is mahigit Php100, cguro po sobrang taas na po yun. Kung mga Php50, pwede pa nating masasabing reasonable.

  18. admin says:


    Your HR can apply the refund on your behalf. BIR will always refund if there is a need for a refund.

  26. benreyes says:

    Hi good day po, ano po kayang mali sa tax computation ng employer namin? kasi po last year ng nagkaroon po ako ng refund na more than 20,000.00php. At tama po ba na installment ang refund namin include po nila every payroll as adjusment po sa salary ko.More than 5 years na po nila ginagawa yon sa lahat ng employee na meron refund.

  27. benreyes says:

    Add ko lng po, di po talaga pwede magpost ang employer ng list of employee na meron tax refund.Kaya lng po namin nalalaman na may refund kami kapag meron na adjustment sa pay slip namin. Other deduction naman sa mga payable.

  28. admin says:


    Mas maganda po na save nyo ang mga payslip ninyo with the tax data in there. Then at the end of the year, you can go to BIR and ask for the total and compare it with yours. Yan lng po ang masa suggest ko.

  29. admin says:

    based sa calculation ko gamit ang tool, from 292.54 to 394.78 ang range ng tax mo.

  30. admin says:


    Period: Monthly
    Basic Salary: 31351
    Status: Single
    SSS/GSIS: 2821.59
    Philhealth: 375

    I used the tool and i arrived with the answer
    Tax: 5082.99

    Curious lang po ako.. everytime po ba na mag remit ng withholding taxes ang isang employer sa BIR ay may kasama ba itong list of employees with the correspnding TINs? is it like the same sa pag report po gaya ng RF1 sa philheath or R3 sa SSS?

    ive heard from one bookkeeper na kpag dw nkapag remit na ng taxes (1601C bir form) ay di n raw maibbgay ng BIR mismo if in case may refund BUT ang employer na raw ang respnsible na magbbalik sa mga emplyado? how true?

    hope to hear from you the soonest!

    thanks po!

    Hi! Just want to know how tax on 13th month pay was computed?
    In our present management all 13th month was taxed kahit less than 30k. reason nila para di daw kami mabigatan sa year end tax. pero sobra naman po yata laki ng tax…yung iba umabot po ng 25% of their 13th month po ba yun?

  34. tootz says:

    gusto ko lang po sana malaman kung may tax table din po na ginagamit sa pag compute ng tax sa 13th month pay.

    thanks po!

  35. admin says:

    yung 13th month pay pag less than 30K, non-taxable. at the end of the year at sobra ang nabayad na tax, may refund dapat yun.

  36. admin says:

    non-taxable yung 13th month pay pag less than 30K. sa pgkakaalam namin, yung sobra sa 30K, idadagdag sa taxable income for the year.

  37. admin says:

    Yes po. Same pa rin yung formula.

  38. admin says:

    ito po yung tool

    base sa tool, yung tax mo is 6,776.67.

  40. Leen Aquino says:

    May I ask about my case….

    from S to HF1 w/one child, na update po ung tax ko 15aug12
    at wla akong kaltas ng TAX hanggang 30sep12. pero end of

    wlang kaltas ng TAX but 30dec11 may TAX REFUND SYA???

    UNFAIR!!! po diba…

    anu po ba ung mali??? HR po ba???

  41. admin says:

    hello Leen, supposedly, ang whole year mo maapektuhan ng change of status mo. Yung HF1 na bale ang gagamitin sa whole year. Try to ask your HR about your annual tax calculation na gamit ang HF1 and the total tax you have paid. Kung may sobra, dapat yung ang tax refund.

  42. jipri says:

    Hi Admin,

    I’d like to ask how tax refund is computed.

    I joined a company March of 2012 as probationary with salary of 15,000 and got regularized September 2012 with 16,000 as basic. I would want to be familiar and have knowledge on how tax refund is computed.

    I hope I could get a response as soon as possible.

    THANK YOU :)
