The 8% vs graduated choice, explained

If you are self-employed or a professional in the Philippines, the BIR gives you a choice that ordinary employees do not have. You can be taxed under the regular graduated rates (the same 0%–35% brackets everyone uses, applied to your income after deductions), or you can elect a flat 8% income tax on your gross sales or receipts above ₱250,000 — a single rate that takes the place of both the graduated income tax and the 3% percentage tax. The right choice can save you tens of thousands of pesos a year, and it depends almost entirely on how much you can deduct.

How the comparison works

The 8% side is simple: the calculator takes your gross income, subtracts the ₱250,000 that purely self-employed taxpayers are allowed, and applies 8%. The graduated side first reduces your gross by your deductions, then runs the result through the BIR brackets. You can deduct in one of two ways: the Optional Standard Deduction (OSD), a flat 40% of your gross that needs no receipts, or itemized deductions, your actual documented business expenses. If your real expenses are higher than 40% of your income, itemizing usually wins; if they are lower, the OSD — or the 8% option — usually wins.

There are two eligibility rules to keep in mind, both built into the calculator. The 8% option is available only if your gross sales for the year do not exceed the ₱3,000,000 VAT threshold and you are not VAT-registered; above that, you must use the graduated rates. And the ₱250,000 reduction inside the 8% computation applies only to purely self-employed individuals — mixed-income earners who also have a salary do not get it twice, because it is already part of the graduated schedule on their compensation.

These are the rates the graduated side of the calculator applies to your income after deductions. The 8% option replaces this entire schedule with a single flat rate.

Frequently Asked Questions

Who can use the 8% tax option?

Purely self-employed individuals and professionals whose gross sales or receipts do not exceed ₱3,000,000 for the year and who are not VAT-registered. It is elected in the first-quarter return and applies for the whole year (BIR RR 8-2018).

Is the ₱250,000 deducted in both options?

Effectively yes, but differently. Under the 8%, purely self-employed taxpayers subtract ₱250,000 from gross before applying 8%. Under the graduated rates, the ₱250,000 is the 0% first bracket — it is already in the schedule, so it is not subtracted separately.

What is the Optional Standard Deduction (OSD)?

The OSD is a deduction equal to 40% of your gross sales or receipts that individual taxpayers may claim instead of itemizing — no receipts required (NIRC §34(L), BIR RR 8-2018). It is the simplest way to reduce your taxable income on the graduated side.

When is 8% better than graduated?

The 8% option tends to win for freelancers with low deductible expenses, because graduated taxation only helps when your deductions are large. If your documented expenses exceed 40% of your income, itemized graduated often beats the 8% — which is exactly what the calculator above settles for your numbers.
