If you run a business on your own in the Philippines, you have probably weighed two structures: a simple sole proprietorship, or a One Person Corporation (OPC). The choice changes who is liable for the business debts and, crucially, how the business is taxed. This guide explains, in plain English, what an OPC is, the law that created it, how it is taxed as a domestic corporation, the dividend question that creates potential double taxation, and how it compares to a sole proprietorship — with a worked example at the end.
What Is a One Person Corporation (OPC)?
A One Person Corporation, or OPC, is a corporation with only a single stockholder, who may be a natural person (a living individual), a trust, or an estate. It lets a solo entrepreneur operate through a corporation without finding partners or co-incorporators, which the older Corporation Code effectively required.
The key feature is that an OPC is a separate legal entity from its stockholder, with its own legal personality, its own Tax Identification Number (TIN), and its own assets. This is the biggest difference from a sole proprietorship, and the source of both its main advantage (limited liability) and its main tax cost (possible double taxation).
Legal Basis: The Revised Corporation Code (RA 11232)
The OPC was created by the Revised Corporation Code, which is Republic Act No. 11232, enacted in 2019. Before RA 11232, forming a corporation generally required at least five incorporators, which pushed solo entrepreneurs toward sole proprietorships or partnerships. The Revised Corporation Code removed that barrier by allowing a single stockholder to incorporate.
Because it is created under the Corporation Code, an OPC is regulated by the Securities and Exchange Commission (SEC), not the DTI that registers sole proprietorships. You can read the authoritative rules on OPC formation on the official SEC website. SEC oversight is also part of what makes an OPC more burdensome to maintain than a sole proprietorship.
Separate Legal Entity and Limited Liability
Because the OPC is a separate legal entity, the stockholder enjoys limited liability — personal assets are generally protected from the corporation's debts. If the OPC owes suppliers, defaults on a loan, or is sued, claimants normally look to the corporation's assets, not the stockholder's house, savings, or other personal property.
A sole proprietorship offers no such shield: proprietor and business are one, so business liabilities can reach the owner's personal assets directly. The trade-off is that the OPC's separate personality also means its income is taxed in its own right before any money reaches the stockholder. Note that "limited liability" is a general rule, not an absolute guarantee — courts can set it aside in cases of fraud or bad faith — but for an honestly run OPC the shield normally holds.
How an OPC Is Taxed: As a Domestic Corporation
This is the part most new OPC owners get wrong. An OPC is NOT taxed as an individual. Because it is a corporation, it is taxed as a domestic corporation, and its income is reported on a corporate income tax return — not on the owner's personal return the way a sole proprietorship's income would be.
So the OPC itself computes and pays corporate income tax on its net taxable income — gross income minus allowable deductions. Those deductions include the same choice between the 40% Optional Standard Deduction (OSD) and itemized expenses available to individual taxpayers under Section 34(L)(1) of the NIRC. Whatever remains after corporate tax may then be distributed to the stockholder, and that distribution can carry its own tax.
Corporate Income Tax Rates Under the CREATE Law (RA 11534)
The corporate income tax rates are set by the CREATE Law — formally Republic Act No. 11534, enacted in 2021 — which set up a two-tier system based on the size of the corporation:
- Regular rate of 25% — the default rate that applies to most domestic corporations.
- Reduced rate of 20% — available to a domestic corporation whose net taxable income does not exceed ₱5,000,000 and whose total assets do not exceed ₱100,000,000 (excluding the value of the land on which its business is situated).
Both thresholds must be met for the 20% rate. An OPC earning ₱4,000,000 but holding ₱150,000,000 in assets still pays 25%, because it fails the asset test; one with low assets but more than ₱5,000,000 in net taxable income also stays at 25%. Most genuinely small OPCs clear both thresholds and qualify for 20%.
Deductions: OSD and Itemized Expenses at the Corporate Level
The OPC first subtracts its allowable deductions from gross income. Two routes are available, mirroring the choice self-employed individuals face:
- Optional Standard Deduction (OSD) — a flat 40% of gross income, with no need to itemize. Quick and favorable for low-overhead businesses, so many service-type OPCs adopt it. See our OSD guide for the full mechanics.
- Itemized deductions — actual, substantiated expenses such as salaries, rent, utilities, and depreciation. Better when real costs run above 40% of gross income.
The choice is made annually on the corporate return — one method per year, switchable the following year. The corporate rate then applies to whatever is left after these deductions, not to gross receipts.
Dividends and the 10% Final Withholding Tax
Once the OPC pays corporate income tax, the remaining profit belongs to the corporation. To move it to the stockholder personally, the OPC typically declares a dividend, which is subject to a final withholding tax.
For a resident citizen receiving cash or property dividends from a domestic corporation, that rate is 10%. The corporation withholds the 10% and remits it to the BIR, and the stockholder receives the remaining 90%. It is a final tax, not declared again as graduated income.
The Double Taxation Question
Combine the last two sections and you get the defining tax feature of an OPC: the possibility of double taxation. The same peso of profit can be taxed twice:
- First, at the corporate level — the OPC pays corporate income tax of 20% or 25% on its net taxable income.
- Then, when distributed — the dividend paid to the stockholder is taxed again at 10% as a final withholding tax.
This is the key structural difference from a sole proprietorship, whose income is taxed only once as the proprietor's personal income, with no corporate layer and no dividend event.
Crucially, double taxation bites only on profits actually distributed. Profits the OPC retains and reinvests are taxed once, at the corporate rate — which is why OPCs suit owners who want to grow the business rather than extract every peso each year.
Can the Stockholder Also Draw a Salary?
Yes. The stockholder may also be employed by the OPC and draw a salary. With a genuine employer–employee relationship, payroll, and withholding, that salary is deductible to the OPC (lowering its net taxable income) and taxable to the stockholder as compensation income.
This matters because a salary is a deductible expense while a dividend is not. A reasonable salary therefore moves cash out of the corporation without triggering the dividend tax — it is taxed once, as compensation. The salary must be reasonable and genuinely earned; the BIR can challenge pay that merely disguises a dividend.
Sole Proprietorship vs One Person Corporation
The clearest way to understand the OPC is to place it beside the structure most solo entrepreneurs already know. The table below summarizes how a sole proprietorship and an OPC differ across the dimensions that matter most for tax and risk.
| Feature | Sole Proprietorship | One Person Corporation (OPC) |
|---|---|---|
| Separate legal entity? | No — owner and business are one | Yes — distinct legal personality |
| Liability of the owner | Unlimited — personal assets at risk | Limited — personal assets generally protected |
| Income tax on profits | Individual income tax — graduated 0–35% or 8% flat | Corporate income tax — 20% or 25% |
| Tax when owner takes out profit | None extra — already taxed as personal income | 10% final withholding tax on dividends |
| Double taxation? | No — single layer of tax | Yes, if profits are distributed as dividends |
| Compliance burden | Simpler — DTI registration, lighter reporting | Heavier — audited FS, BIR Form 1702, SEC reports |
The trade-off is plain: the sole proprietorship is simpler and avoids double taxation, but leaves the owner's personal assets exposed; the OPC adds cost and complexity and can be taxed twice, but shields personal assets behind limited liability. For the individual side, see our Sole Proprietorship tax guide.
Worked Example: ₱2,000,000 Net Taxable Income
Consider an OPC with net taxable income of ₱2,000,000 for the year and total assets under ₱100,000,000. Because both the income threshold (₱5,000,000) and the asset threshold (₱100,000,000) are met, the OPC qualifies for the reduced 20% rate. Here is how the tax is computed, and what happens if it then declares dividends.
| Step | Computation | Amount |
|---|---|---|
| 1. Net taxable income | After OSD/itemized deductions | ₱2,000,000 |
| 2. Applicable rate | Income ≤ ₱5M and assets ≤ ₱100M → 20% | 20% |
| 3. Corporate income tax | 20% × ₱2,000,000 | ₱400,000 |
| 4. Dividends declared | Distributed to the stockholder | ₱500,000 |
| 5. Dividend FWT rate | Resident citizen on domestic-corp dividends | 10% |
| 6. Final withholding tax | 10% × ₱500,000 | ₱50,000 |
So the OPC pays ₱400,000 in corporate income tax, and the ₱500,000 dividend it later declares triggers a further ₱50,000 final withholding tax. That ₱50,000 is the visible cost of double taxation — money the stockholder would not have paid had the business been a sole proprietorship, where the same income is taxed only once. The corporate tax applies to the full ₱2,000,000 of profit; the dividend tax applies only to the portion distributed.
Compliance Requirements of an OPC
Because it is a corporation, an OPC must meet corporate-grade obligations. At a minimum, it must:
- Keep books of accounts — accounting records, registered with the BIR, that substantiate its income and expenses.
- File an Audited Financial Statement (AFS) with the BIR — financial statements examined and signed by an independent Certified Public Accountant, which sole proprietorships below certain thresholds can avoid.
- File the corporate income tax return (BIR Form 1702) — the annual return through which the corporate income tax is reported, along with any quarterly filings.
- Comply with SEC reporting — the filings and notifications the Revised Corporation Code requires of corporations, such as appointing a nominee and certain annual submissions.
These obligations mean real, recurring cost — accountant's and audit fees, plus the time to keep corporate records and meet deadlines. A sole proprietorship is markedly simpler and cheaper to keep compliant, which is why many small operators accept its unlimited liability.
When an OPC Makes Sense, and When a Sole Proprietorship Is Simpler
There is no universally "better" structure. An OPC tends to make sense when the risk and credibility factors outweigh the extra cost and tax:
- Risk protection — if your business takes on contracts, debt, or liabilities that could exceed what you would personally risk losing, the limited-liability shield protects your personal assets.
- Credibility — some clients, banks, and government suppliers prefer or require dealing with a registered corporation.
- Reinvestment — if you intend to keep most profits inside the business to grow it, the OPC's single-layer corporate tax on retained earnings is efficient, since double taxation bites only on distributed dividends.
Conversely, a sole proprietorship is simpler and cheaper, and is often the right call when the business is small, low-risk, and the owner wants to draw out most of the profit to live on. You avoid the audit and SEC filings, you pay individual income tax once (graduated 0–35%, or the 8% flat rate), and there is no dividend layer. The decision comes down to weighing asset protection and reinvestment against lower cost and single taxation.

Is an OPC taxed as an individual or as a corporation?
As a corporation. An OPC is a separate legal entity, so it is taxed as a domestic corporation and pays corporate income tax (20% or 25% under CREATE) on its net taxable income. It does not file the individual income tax return that a sole proprietor files.
Why is there double taxation in an OPC?
Because profits are taxed once at the corporate level (20% or 25%) and again when distributed as dividends (10% final withholding tax). It applies only to profit actually paid out; profit retained in the business is taxed once, at the corporate rate.
Can I avoid the dividend tax by paying myself a salary instead?
A reasonable salary paid to the stockholder as a genuine employee is deductible to the OPC and taxed once as compensation — it never becomes a dividend, so it avoids the dividend tax. The salary must be reasonable and truly earned; the BIR can challenge pay that merely disguises a dividend.
Key Takeaways
- A One Person Corporation (OPC) has a single stockholder and was created by the Revised Corporation Code (RA 11232, 2019).
- It is a separate legal entity, so the stockholder enjoys limited liability — personal assets are generally protected from corporate debts.
- An OPC is taxed as a domestic corporation: corporate income tax of 25%, reduced to 20% when net taxable income ≤ ₱5,000,000 and total assets ≤ ₱100,000,000 (CREATE Law, RA 11534).
- Corporate tax applies to net taxable income — gross income less allowable deductions (including the 40% OSD or itemized expenses).
- Dividends to a resident citizen carry a 10% final withholding tax, creating potential double taxation — unlike a sole proprietorship, taxed once as personal income.
- A salary to the stockholder is deductible to the OPC and taxed once as compensation, avoiding the dividend tax.
- OPC compliance is heavier: books of accounts, an audited financial statement, BIR Form 1702, and SEC reporting.
