Small Business Tax Regime Planner

The decision every Filipino freelancer and small shop faces

When you register a business or freelance practice with the BIR, you choose how your income is taxed, and that choice can swing your bill by tens of thousands of pesos a year. This planner weighs the three routes open to a small operator: the 8 percent flat tax on gross, the graduated income tax paired with the 3 percent percentage tax, and the VAT path that becomes compulsory once you grow past the registration threshold. It reads your projected annual gross and your expense ratio, then estimates each route's annual tax and names the cheapest legal one. The expense ratio is the lever most people overlook, because it is what decides whether a tax on revenue or a tax on profit serves you better.

How the three routes are estimated

The 8 percent flat tax, as modelled here, applies 8 percent to your gross sales after a PHP 250,000 reduction, and it replaces both income tax and percentage tax in one stroke, which is why low-cost service earners often favour it. The graduated route taxes your profit (gross minus expenses) on the TRAIN brackets that start at zero below PHP 250,000 and climb to 35 percent, then adds the 3 percent percentage tax on gross. The VAT path applies the same graduated income tax to profit but layers on net VAT, which this calculator models simply as 12 percent of sales less 12 percent of expenses. Both the 8 percent option and the percentage-tax route are only open while your gross stays under the PHP 3,000,000 VAT registration threshold; cross it and the planner marks them unavailable and points you to the VAT path. These rates, the PHP 250,000 reduction, and the PHP 3,000,000 threshold are the figures the calculator assumes, and you should confirm the current numbers with the BIR, since the brackets and thresholds are periodically revised and the VAT estimate here is deliberately simplified.

A PHP 2,500,000 practice at a 35 percent expense ratio

Take a consultant projecting PHP 2,500,000 in gross with expenses running 35 percent, so PHP 875,000 in costs and PHP 1,625,000 in profit. This is under the VAT threshold, so all three routes are on the table. The 8 percent flat tax works on PHP 2,500,000 less PHP 250,000, giving PHP 180,000. The graduated-plus-percentage route taxes the PHP 1,625,000 profit at PHP 308,750, then adds PHP 75,000 of percentage tax for PHP 383,750. The 8 percent flat tax wins by a wide margin.

The contrast is stark at this margin: the flat route costs barely half the graduated one. The chart sets the two available routes side by side.

When the answer flips

The 8 percent flat tax is not always the winner; it shines for low-expense earners. Push the expense ratio up and the graduated route, which taxes only your thin profit, starts to close the gap and eventually overtakes the flat tax, since 8 percent of high gross can exceed the graduated tax on a small profit. A trader buying and reselling stock at a 70 or 80 percent cost ratio is a classic case where graduated wins. The practical move is to run your real expense ratio through this planner, not a guess, because that one input is what tips the decision. A common mistake is electing 8 percent at registration and forgetting that the election is annual and that crossing PHP 3,000,000 forces you out of it mid-stream into VAT.

Who can actually choose the 8 percent flat tax?

It is open to self-employed individuals and professionals whose gross stays under the PHP 3,000,000 VAT threshold, and you elect it, typically on your first quarterly return for the year. Mixed-income earners apply it differently, without the PHP 250,000 reduction on their business income, since that reduction is meant to stand in for the income-tax-free band a pure business earner would otherwise use. Confirm your eligibility and the election mechanics with the BIR, because missing the election window can lock you into the graduated route for the year.

Should I voluntarily register for VAT even if I am below the threshold?

Sometimes. If your customers are themselves VAT-registered businesses, they can claim back the VAT you charge, so VAT registration need not cost them anything and lets you reclaim input VAT on your own purchases. If you sell mainly to consumers who cannot reclaim it, staying non-VAT and on the 3 percent percentage tax usually keeps your prices more competitive. This planner treats VAT as the route once you are over the threshold; below it, weigh your customer mix before opting in voluntarily, and confirm the rules with the BIR.
