8% vs Graduated: the exact numbers for 2026

Short answer — two crossovers, because of percentage tax: comparing income tax only, the crossover is ₱937,500 of gross receipts. But in the real world, non-VAT taxpayers on graduated rates also owe 3% percentage tax on gross (BIR 2551Q) — while electing 8% replaces it. With percentage tax included, the crossover drops to ≈₱535,700: above that, 8% almost always wins. Here's the full math, the mistakes people make, and when the rule of thumb breaks.

The two options, precisely

Option A — 8% flat: you pay 8% on gross receipts over ₱250,000 (the first ₱250k stays exempt). No deductions, simpler compliance, but requires gross ≤ ₱3M and you keep paying percentage tax obligations replaced by the 8% election.

Option B — graduated + OSD: deduct 40% of gross as the Optional Standard Deduction, then apply the TRAIN rates (0% to 35%) to the remaining 60%.

Crossover #1: ₱937,500 (income tax only)

Below ₱1M of taxable income the graduated rate is 20% — but that 20% only hits 60% of your gross (after OSD), which is effectively 12% of gross, minus the cushion of the ₱250k exemption and bracket base. The algebra: 8%×(g−250,000) = 22,500 + 20%×(0.6g − 400,000) solves to g = ₱937,500. Both options compute ₱55,000 exactly there.

Per R.A. 10963 (TRAIN) individual rate tables; assumes OSD, no itemized deductions.

When the rule of thumb breaks

• Your actual expenses exceed 40% of gross → itemized deductions beat OSD, pushing graduated further down. 8% wins less often.
• You're VAT-registered → VAT is a separate 12% on top; the income-tax comparison stands but cash flow changes.
• Gross over ₱3M → 8% is off the table entirely; you're graduated (and generally VAT-registered).
• Employed + freelance → your salary is taxed (and withheld) separately; the 8%-vs-graduated election applies to the freelance side. The calculator's mixed mode handles this.

The mistakes that cost money

• Picking 8% "for simplicity" at ₱500k gross — that's ₱16,500/year donated to the BIR vs graduated+OSD.
• Forgetting the ₱250k exemption applies to 8% too — some calculators charge 8% on the whole gross; correct is 8% on the excess.
• Not re-deciding annually — your income crosses the ₱937.5k line and nobody tells you. Recompute each January.
• Confusing percentage tax with income tax — the 8% election replaces the 3% percentage tax for non-VAT taxpayers; graduated does not.

Decision, in one paragraph

Crossover #2: ≈₱535,700 (with 3% percentage tax — the real-world one)

If you're non-VAT on graduated rates, add 3% of gross (Form 2551Q) to Option B — the 8% election replaces percentage tax entirely. The equation becomes 8%×(g−₱250k) = [graduated on 60% of g] + 3%×g, which solves to g ≈ ₱535,714. Two worked checks: at ₱600k gross, 8% costs ₱28,000 vs graduated ₱16,500 + ₱18,000 PT = ₱34,500 → 8% wins. At ₱400k, both compute ₱12,000 — dead tie. Below ₱250k gross, 8% owes ₱0 while graduated still owes 3% of gross — another quiet reason small freelancers pick 8%.

Decision, in one paragraph

Non-VAT and comparing real cash out? The line is ≈₱535k gross: below it graduated+OSD usually pays less (if your books are in order), above it 8% wins and keeps winning. VAT-registered or comparing income tax in isolation? Use ₱937.5k. Under ₱250k? 8% = ₱0. Then verify with your RDO before filing; this is a calculator and a guide, not legal advice.

Old one-paragraph rule (income tax only)

Under ~₱930k gross and expenses under 40% of revenue? Graduated + OSD. Over ~₱940k, or you value not maintaining books of accounts at 8%'s slightly higher tax? Take 8%. Between ₱900k and ₱1M, the difference is under ₱3,000 — decide on compliance preferences.
