Graduated Rates vs the 8% Income Tax Option

Two Ways to Pay Tax on Self-Employment Income

If you earn income as a sole proprietor, freelancer, or professional in the Philippines, the Bureau of Internal Revenue gives you a choice on how your income tax is computed. You can either use the graduated income tax rates under the TRAIN law together with the 3% percentage tax on gross sales or receipts, or you can elect the 8% flat income tax on gross sales or receipts in excess of ₱250,000, which is paid in lieu of both the graduated income tax and the percentage tax. The choice matters because, depending on your revenue and expenses, one option can save you tens of thousands of pesos a year compared to the other.

This choice is only available to self-employed individuals and professionals, including mixed-income earners on the business or practice-of-profession portion of their income. It is not available to VAT-registered taxpayers or to anyone whose gross sales or receipts exceed the current VAT threshold of ₱3,000,000 in a taxable year — that threshold is reviewed periodically, so confirm the latest figure on the BIR website before filing. Employees earning purely compensation income have no need to choose; their withholding tax already follows the graduated table.

How Graduated Rates Plus Percentage Tax Work

Under the graduated system, your taxable net income — gross sales or receipts less allowable deductions, either itemized or the 40% Optional Standard Deduction (OSD) — is taxed using the TRAIN law brackets, which remain in effect for individuals:

• Not over ₱250,000: 0%
• Over ₱250,000 up to ₱400,000: 15% of the excess over ₱250,000
• Over ₱400,000 up to ₱800,000: ₱22,500 plus 20% of the excess over ₱400,000
• Over ₱800,000 up to ₱2,000,000: ₱102,500 plus 25% of the excess over ₱800,000
• Over ₱2,000,000 up to ₱8,000,000: ₱402,500 plus 30% of the excess over ₱2,000,000
• Over ₱8,000,000: ₱2,202,500 plus 35% of the excess over ₱8,000,000

On top of this, non-VAT registered taxpayers under this option pay the 3% percentage tax (BIR Form 2551Q) on gross sales or receipts, regardless of whether the business turned a profit. This is a separate, cumulative tax on top of income tax — not an alternative to it.

Example: A bookkeeper operating as a sole proprietor earns ₱1,200,000 in gross receipts for the year and uses the 40% OSD instead of itemizing expenses. Taxable net income is ₱1,200,000 less 40% (₱480,000), or ₱720,000. Using the table above: ₱22,500 + 20% of (₱720,000 − ₱400,000) = ₱22,500 + ₱64,000 = ₱86,500 in income tax. Add 3% percentage tax on the full ₱1,200,000 gross receipts, or ₱36,000. Total tax liability: ₱122,500.

How the 8% Flat Tax Works

The 8% option is simpler to compute and to comply with. It is charged on gross sales or receipts in excess of ₱250,000 for the year, and it replaces both the graduated income tax and the 3% percentage tax entirely — you no longer file 2551Q at all while under this option. There are no deductions to track, which is precisely why it appeals to service providers and professionals with few deductible expenses.

Using the same bookkeeper above with ₱1,200,000 in gross receipts: (₱1,200,000 − ₱250,000) × 8% = ₱950,000 × 8% = ₱76,000. That is the entire tax due for the year — no separate percentage tax to add. Compared to the ₱122,500 total under graduated rates plus percentage tax, this taxpayer saves ₱46,500 by electing the 8% option.

Which Option Actually Costs Less?

The honest answer is: it depends on your expense ratio. The 8% option tends to win for consultants, freelancers, and professionals whose operating costs are low relative to revenue, because they have little to gain from itemizing or even claiming the 40% OSD. The graduated-plus-percentage-tax combination tends to win for businesses with substantial documented costs — retailers, traders, or anyone with real cost of goods sold and overhead — because itemized deductions can push taxable net income, and therefore the income tax due, down far more than a flat 8% on gross would allow.

As a rule of thumb, if your actual deductible expenses exceed roughly 40-50% of your gross sales or receipts, run the numbers on graduated rates before committing to 8%, since the percentage tax savings from switching are usually smaller than the deduction benefit you would give up. If your expenses are modest, the 8% option is usually both cheaper and far less work at filing time. In Kontabler, once you tag your business as using the 8% option or the graduated method, every recorded sale is automatically computed against the correct basis, and your quarterly tax due — whether it's the 8% flat computation or the graduated table plus 3% percentage tax — is posted to your books automatically, so you can compare both scenarios before locking in your election.

Electing, Switching, and Filing Deadlines

You signify your choice of the 8% option either when you first register with the BIR (via Form 1901, or 1905 if updating an existing registration) or on your first quarterly income tax return of the taxable year, BIR Form 1701Q, due on or before May 15. Once made, the election is irrevocable for that taxable year — you cannot switch back to graduated rates mid-year simply because your circumstances changed. If you fail to signify a choice, the BIR defaults you to the graduated rates.

• 1701Q (quarterly income tax): due May 15, August 15, and November 15, with the annual return (1701) due April 15 of the following year.
• 2551Q (percentage tax, applicable only if you are under graduated rates and not VAT-registered): due within 25 days after the close of each taxable quarter.

Two situations force a mid-year shift regardless of your election: if your actual gross sales or receipts exceed the ₱3,000,000 VAT threshold, you must register as a VAT taxpayer and use graduated rates going forward, with earlier quarters recomputed accordingly; and under the Ease of Paying Taxes (EOPT) Act, the ₱500 annual registration fee (Form 0605) has been removed altogether, and businesses may now issue a single Sales or Commercial Invoice for both cash and credit transactions instead of separate receipts and invoices, simplifying documentation either way. Filing late under either option exposes you to a 25% surcharge plus 12% annual interest on the unpaid tax, so whichever method you choose, keep your quarterly filings current.

Because the election locks you in for the full year, the smartest approach is to project your gross sales and estimate your real expense ratio at the start of the year — or as soon as you register — rather than deciding based on a single good or bad quarter.
