What is a Zonal Value?
The Bureau of Internal Revenue (BIR) assigns a zonal value to every classified area in the Philippines. It represents the minimum market value per square meter used as the tax base for real property transactions. In SIAYAN, Zamboanga del Norte, values range from ₱1.5 to ₱195 per sqm across 11 barangays.
Common Uses
- Sale of property. Capital gains tax (CGT) and documentary stamp tax (DST) are based on the selling price or zonal value, whichever is higher.
- Inherited property. Estate tax computation uses zonal value as the fair market value of the property.
- Donated property.Donor’s tax base includes the zonal value.
- Checking an asking price. A price below zonal value may signal urgency or trigger BIR scrutiny on the transaction.
Frequently Asked Questions
How do I use the tax calculator?▾
Scroll down to the calculator. Click any result row to auto-fill the zonal value, then enter the lot area in sqm. The calculator will estimate your Capital Gains Tax, Documentary Stamp Tax, and Transfer Tax based on BIR formulas.
What happens if the selling price is below the zonal value?▾
The BIR uses the higher of the two values as the tax base. If a property sells for less than its zonal value, taxes are still computed using the zonal value. This is why properties sold at prices below zonal value can raise flags during BIR processing.
How current is this data?▾
Data for SIAYAN is sourced from the latest BIR zonal value update (2018). Zonal values are updated by BIR periodically. Always verify with your RDO before processing a transaction.
Why do some areas have more entries than others?▾
BIR assigns entries at street or barangay level depending on how granularly each RDO mapped the area. Urban and commercial zones typically have more entries. The “Areas with Most BIR Data” card above shows the most granularly covered areas in SIAYAN.
