Optional Standard Deduction (OSD) is a tax method in the Philippines. It allows taxpayers to deduct a fixed 40% of gross income instead of itemizing actual business expenses.
Under OSD, the Bureau of Internal Revenue (BIR) allows a standard deduction without requiring receipts for individual expenses. Tax is computed only on the remaining 60% of income, making compliance simpler.
Why Choose OSD?
OSD is commonly chosen by professionals and entrepreneurs whose actual expenses are relatively low.
- Simpler compliance: Individual taxpayers are not required to submit an Audited Financial Statement (AFS).
- Potential tax savings: When actual expenses are below 40%, OSD results in lower taxable income.
How OSD Works
- The choice to use OSD must be made in the First Quarter Income Tax Return (BIR Form 1701Q or 1702Q).
- Once selected, OSD applies for the entire taxable year.
- Individuals: 40% of gross sales or receipts
- Corporations: 40% of gross income (sales less cost of goods sold)
This method affects how income is reported and finalized when filing Annual Income Tax Returns in the Philippines.
OSD vs Itemized Deductions
OSD offers minimal record-keeping and lower audit exposure, while itemized deductions require full documentation of actual expenses and are more suitable for businesses with high operating costs.
Note: Some individuals may instead opt for the 8% Flat Income Tax, which simplifies compliance further. However, OSD may be more tax-efficient for higher-income earners using graduated tax rates.
