What Taxes Apply to an Unregistered Joint Venture?

Introduction

Businesses sometimes join forces for a single construction project, supply arrangement, property venture, or other commercial undertaking without forming a corporation or registering a formal partnership. Although this arrangement may appear informal, Philippine tax law may treat the participants as having created a taxable joint venture or partnership.

The absence of a separate juridical personality, partnership registration, or corporate registration does not by itself remove tax obligations. When persons pool money, property, services, or expertise, share risks, and divide commercial profits, the Bureau of Internal Revenue (BIR) may examine the arrangement as a taxable business enterprise.

This distinction is important. A joint venture that qualifies for the statutory exclusion applicable to certain construction projects may receive special tax treatment. An ordinary unregistered joint venture, however, may be subject to corporate income tax, business taxes, withholding obligations, registration requirements, invoicing rules, and penalties for noncompliance.

When Does an Informal Arrangement Become a Taxable Joint Venture?

For tax purposes, the substance of the arrangement is more important than its label. The parties need not call themselves “partners” or “joint venturers,” and the agreement need not always follow the formal requirements ordinarily associated with a registered partnership.

In Evangelista, et al. v. Collector of Internal Revenue, General Register No. 9996, 15 October 1957, the Supreme Court recognized that persons who pooled resources to acquire, manage, and lease property for profit could be treated as a partnership or joint venture for tax purposes. The Court emphasized that the conduct and purpose of the enterprise, rather than the absence of formal registration, determine the tax characterization.

The circumstances that may indicate a taxable joint venture include:

• an agreement to contribute money, property, labor, or services;
• a common commercial undertaking or project;
• joint control or management of the activity;
• sharing of profits, losses, or project risks; and
• business operations carried on with some degree of continuity or profit motive.

An arrangement described as a “memorandum of understanding,” “cooperation agreement,” “consortium,” or “project collaboration” may still be treated as a joint venture if its actual terms and implementation show a community of interest in a business undertaking.

Why Registration Status Matters

The National Internal Revenue Code distinguishes between duly registered general partnerships or general professional partnerships and other entities that fall within the statutory meaning of “corporation” for income-tax purposes.

Section 22(B) of the National Internal Revenue Code includes partnerships, joint accounts, associations, and other comparable arrangements within the tax concept of a corporation, subject to stated exclusions. The special treatment for a general professional partnership applies only when the partnership is formed solely to exercise a common profession and no portion of its income arises from trade or business.

Presidential Decree No. 1774 further amended the statutory definition to exclude certain joint ventures or consortia formed for construction projects or petroleum, coal, geothermal, and other energy operations pursuant to a government service contract. This exclusion is specific and should not be extended automatically to every unregistered commercial collaboration.

In Commissioner of Internal Revenue v. Ledesma, General Register No. 17509, 29 April 1970, the Supreme Court explained the different tax treatment of duly registered and unregistered partnerships. A duly registered general partnership is generally not subject to corporate income tax on its partnership income; instead, the partners report their respective distributive shares. An unregistered partnership, by contrast, may be assessed corporate income tax on its profits, while the partners may also be taxed on their shares.

Income-Tax Liability of an Unregistered Joint Venture

An unregistered joint venture engaged in an ordinary commercial enterprise may be treated as a corporation for income-tax purposes. Its taxable income may therefore be subject to corporate income tax under the applicable provisions of the National Internal Revenue Code.

The participants may not avoid the joint venture’s tax liability simply by dividing the receipts among themselves. The BIR may first determine the gross receipts, allowable deductions, taxable income, and income-tax liability of the enterprise. It may then examine whether the participants separately received taxable distributive shares, compensation, management fees, or other income.

The tax consequences may include:

• income tax on the taxable income of the unregistered joint venture;
• income tax on the participants’ respective shares or other payments received;
• value-added tax or percentage tax, depending on the nature and level of receipts;
• withholding taxes on payments to employees, suppliers, contractors, professionals, or participants when legally applicable; and
• registration, invoicing, bookkeeping, and information-reporting obligations.

The precise tax computation depends on the character of the activity, the taxable period, the gross receipts, the applicable tax regime, and the documents supporting the reported expenses and payments.

Special Rule for Certain Construction Joint Ventures

Not every construction joint venture is treated in the same manner as an ordinary taxable unregistered business. Administrative rulings recognize a special treatment for a joint venture formed exclusively for a specific government construction project, provided the required conditions are satisfied.

Among the conditions reflected in the relevant BIR rulings are that the co-venturers are licensed local contractors, are duly accredited or registered with the Philippine Contractors Accreditation Board, and formed the joint venture solely to undertake the specified construction project.

BIR Ruling No. 1421-2018, BIR Ruling No. 1309-2018, BIR Ruling No. 707-2019, BIR Ruling No. 708-2019, BIR Ruling No. 187-2021, and BIR Ruling No. 216-2022 reflect the BIR position that a qualified construction joint venture may be exempt from corporate income tax and the two-percent creditable withholding tax on gross payments, while the individual co-venturers remain liable for tax on their respective shares of the joint venture’s net income.

That treatment is not a blanket exemption for all construction collaborations. It depends on compliance with the conditions stated in the governing law, regulations, project documents, contractor registrations, and the applicable BIR ruling. A joint venture that undertakes unrelated projects, admits unqualified participants, operates beyond the approved project, or fails to maintain the required records may not qualify.

Withholding Tax on Distributive Shares

The tax treatment of payments to joint-venture participants must be distinguished from the withholding rules applicable to partners of a general professional partnership.

In Request for Review of Bureau of Internal Revenue Ruling No. JV-317-2022 dated 28 June 2022, DOF Opinion No. 018-2022, 7 November 2022, the Department of Finance stated that the withholding rule for income payments to partners of a general professional partnership could not automatically be applied to the distributive shares of co-venturers in a non-taxable joint venture. The opinion reasoned that a general professional partnership and a joint venture are not similar entities for this purpose and that withholding taxes must have a specific legal basis.

This does not mean that every payment connected with a joint venture is free from withholding. Payments for professional services, compensation, rentals, contractors’ services, interest, dividends, or other separately classified transactions may still carry withholding obligations under the applicable provisions and regulations.

The parties should therefore identify the legal character of every payment instead of treating all transfers as a tax-free “profit share.”

Official Receipts, Invoices, and Proof of Sales

A joint venture that conducts business must properly document its sales, services, collections, purchases, and expenses. Profit-sharing arrangements do not replace the obligation to issue the required invoice or other prescribed sales document for a sale of goods or rendition of services.

Failure to issue the required document can create several problems. It may expose the enterprise to tax assessments based on third-party information, weaken the deductibility of expenses, prevent customers from substantiating purchases, and support the imposition of civil or criminal penalties.

Section 258 of the National Internal Revenue Code penalizes the unlawful pursuit of business when a person carries on a business subject to an annual registration fee without paying the required tax. The provision imposes a fine of not less than P5,000 but not more than P20,000 and imprisonment of not less than six months but not more than two years, upon conviction, subject to the circumstances stated in the law.

Separate violations may arise from failure to register, failure to file returns, failure to keep books, failure to issue invoices, failure to withhold or remit taxes, and submission of false or fraudulent returns. The applicable penalty depends on the specific act, the taxpayer’s status, the amount involved, and the evidence of willfulness or fraud.

Typical Scenarios

Construction Consortium for a Government Project

Two PCAB-licensed local contractors form a joint venture solely to build a government facility. They execute a project-specific agreement, secure the required registrations, maintain separate project books, submit the required documents, and comply with the conditions recognized in the applicable BIR ruling.

This arrangement may qualify for the special treatment applicable to qualified construction joint ventures. The participants should not assume that qualification is automatic merely because the project is government-funded or because the agreement uses the word “consortium.”

Unregistered Property-Leasing Venture

Several individuals contribute money to acquire commercial property, lease it to tenants, manage the property jointly, and divide the rental income. Even without a registered partnership, the arrangement may be treated as a partnership or joint venture for tax purposes under the reasoning of Evangelista, et al. v. Collector of Internal Revenue, General Register No. 9996, 15 October 1957.

The participants may face assessments for income tax, business taxes, withholding taxes, registration penalties, and penalties relating to invoices and books of accounts.

Profit-Splitting Without Sales Documents

A contractor receives payments from a customer and transfers agreed portions to two informal business partners. No invoice is issued by the joint venture, the parties do not maintain project books, and the transfers are described only as “profit sharing.”

The arrangement may be examined as an unregistered taxable business. The absence of invoices and records may make it difficult to establish the actual gross receipts, legitimate expenses, and proper allocation of taxable income. It may also expose the participants to separate penalties for noncompliance.

Recommended Compliance Measures

Persons intending to conduct a joint commercial activity should address tax compliance before receiving project payments or issuing commercial quotations.

1. Classify the arrangement. Determine whether the activity is a partnership, joint venture, corporation, general professional partnership, or another form of business association.
2. Review the statutory exception. If the activity involves construction or energy operations, verify whether the precise statutory exclusion applies and whether all regulatory conditions are met.
3. Register the business and tax accounts. Secure the registrations, permits, books, and invoicing authority required for the business activity.
4. Use a dedicated accounting system. Maintain records of contributions, project receipts, expenses, advances, distributions, and payments to third parties.
5. Issue the required invoices. Ensure that sales and service transactions are documented in the form and manner prescribed by current tax rules.
6. Review every payment category. Determine whether a transfer is a distributive share, compensation, professional fee, reimbursement, contractor payment, rental, interest, or another taxable payment.
7. Obtain written tax advice for unusual projects. A project-specific tax review is particularly important where the parties intend to rely on a construction-joint-venture exception.

Conclusion

An unregistered joint venture is not necessarily an untaxed arrangement. Philippine tax law may look beyond the parties’ terminology and determine liability from the actual pooling of resources, conduct of business, sharing of risks, and division of profits.

The ordinary rule is that a commercial joint venture may be treated as a taxable entity even if it has not been registered as a corporation or partnership. A limited exception may apply to qualified construction joint ventures formed exclusively for specified government projects, but the exception depends on strict factual and regulatory compliance.

Business partners should therefore formalize their arrangement, register the enterprise, issue the required sales documents, keep complete books, classify payments correctly, and verify whether any statutory or administrative exception genuinely applies. Informal profit-splitting without invoices and tax records can result in assessments, penalties, and possible criminal exposure.
