Quick answer: A Philippine tax refund happens when your employer withheld more tax than you owed for the year. In the year-end adjustment the employer recomputes your tax on the whole year and returns the excess, usually in your December pay or your final pay if you leave earlier. You can estimate it with the Withholding Tax Calculator.
This page covers the year-end adjustment. For how monthly deductions work read withholding tax explained, and for the certificate that shows the result see BIR Form 2316.
Why refunds happen
Every payday your employer withholds tax based on that period’s pay, as if you would earn the same amount all year. Your true income tax is computed on the whole year. Because withholding cannot predict the year in advance, the two rarely match.
- Total withholding higher than annual tax: you get a refund.
- Total withholding lower than annual tax: the shortfall is deducted.
The year-end adjustment formula
Under Revenue Regulations 11-2018, in December (or in your last payroll if you leave earlier) the employer does the annualized computation:
Taxable pay for the year (this employer)
+ Taxable pay from previous employer (per Form 2316)
+ Bonuses and benefits above ₱90,000
= Annual taxable compensation
Annual income tax (TRAIN brackets)
− Tax already withheld (this employer + previous employer)
= Refund (negative) or additional tax (positive)The result is added to or deducted from your pay and the adjusted figures appear on your BIR Form 2316.
Worked examples
Example 1: hired in March at ₱30,000 a month
Payroll withheld ₱1,007.55 a month for 10 months, as if you would work all year, which is ₱10,075.50. Your real taxable pay is 10 × ₱27,550 = ₱275,500, so your annual tax is only 15% × (₱275,500 − ₱250,000) = ₱3,825.
Tax withheld ₱10,075.50
Annual tax due − ₱3,825.00
Refund ₱6,250.50Example 2: resigned at the end of June
Six months at ₱30,000 gives taxable pay of 6 × ₱27,550 = ₱165,300, under the ₱250,000 exemption. Annual tax is ₱0, so every peso withheld (6 × ₱1,007.55 = ₱6,045.30) is refunded in your final pay.
Example 3: a big bonus month (you owe, not refund)
A ₱60,000 earner receives a ₱60,000 13th month pay and an ₱80,000 performance bonus. Benefits total ₱140,000, so ₱50,000 is above the ₱90,000 exemption.
Regular taxable pay: (₱60,000 − ₱3,450) × 12 = ₱678,600
Plus taxable bonus excess ₱50,000
Annual taxable compensation ₱728,600
Annual tax = ₱22,500 + 20% × (₱728,600 − ₱400,000) = ₱88,220
Withheld on regular pay: 12 × ₱6,518.40 ₱78,220.80
Additional tax in December ₱9,999.20Bonuses can push you in either direction, which is why December payslips sometimes shrink.
Example 4: two employers in one year
You earned ₱30,000 a month at Company A from January to June and the same at Company B from July to December. If you give Company B your Form 2316 from Company A, B annualizes both and the total tax is ₱12,090. If you do not, B sees only 6 months (₱165,300 taxable, tax ₱0) and refunds the ₱6,045.30 it withheld. Your two employers have then collected only ₱6,045.30 against a true bill of ₱12,090. You would owe about ₱6,045 when you file your own return, because you cannot use substituted filing. Always hand over your old 2316.
Who usually gets one
- Mid-year hires, as in Example 1.
- Resigned or separated employees, as in Example 2.
- Employees with unpaid leave or months of reduced pay.
- Those whose benefits turned out exempt, such as 13th month pay up to ₱90,000 or de minimis benefits.
- Anyone who gave HR a late 2316 from a previous employer.
If you are on a steady full-year salary without bonuses, expect little or nothing.
How much will you get?
Estimate it yourself in five minutes. Use the Year-end adjustment tab of the Withholding Tax Calculator with your year’s taxable pay, your contributions, your 13th month and bonuses, and the tax withheld shown on your payslips. For the annual-tax side alone use the Income Tax Calculator. The numbers should match the “tax due” line of your Form 2316.
If you have multiple employers
With two or more employers in the year, the BIR does not allow substituted filing. File Form 1700, combine both incomes, and claim the tax credit for all tax withheld. See the income tax return guide for the form and the deadline.
If you still owe tax
If the adjustment shows extra tax, it is normally deducted from your December pay or final pay. If you have other income that was not withheld, you may also need to file and pay by April 15.
