Interest Deduction Limit on Shareholder Loans in the Philippines

Under Philippine tax law, interest paid on a shareholder loan is generally deductible from gross income only if it is an ordinary and necessary business expense, is paid on a valid indebtedness, and is supported by proper documentation. The National Internal Revenue Code of 1997 (NIRC), as amended by Republic Act No. 10963 (the TRAIN Law), allows a deduction for interest expense under Section 34, but the deduction is not unlimited. Where the lender is a shareholder or related party, the Bureau of Internal Revenue scrutinizes the transaction closely because payments may be treated as disguised dividends or unreasonable compensation rather than genuine interest.

What the law says about interest expense

Section 34 of the NIRC, as amended, allows deductions from gross income for ordinary and necessary trade, business, or professional expenses. Interest paid on indebtedness incurred in the conduct of trade or business falls within this category, provided the indebtedness is valid and the interest rate is reasonable.

The TRAIN Law amended Section 34 but retained the framework that deductions must be substantiated. A taxpayer claiming interest expense must show that the loan exists, that the interest was actually paid or accrued, and that the transaction has a genuine business purpose. The deduction is not automatic simply because a payment is labeled "interest."

The related-party problem

When the lender is a shareholder, the BIR may recharacterize the interest payment. If the loan terms are not arm's-length, the interest may be treated as a dividend or as excessive compensation. This matters because dividends are subject to different tax treatment, and excessive interest can be disallowed entirely.

The risk is highest when the shareholder is also an officer or controlling owner. In those cases, the BIR examines whether the company could have borrowed from an unrelated bank on similar terms. If the shareholder loan carries an above-market rate, the excess may be disallowed. If the loan has no written terms, the entire deduction may be challenged.

Documentation the BIR expects

To support an interest deduction on a shareholder loan, the borrower should maintain:

• A written loan agreement stating the principal, interest rate, maturity, and payment terms.
• Proof that the funds were actually received and used for business purposes.
• Evidence of actual interest payments, such as bank records or official receipts.
• A comparison showing that the interest rate is comparable to prevailing market rates.
• Board resolutions approving the loan, especially for corporate borrowers.

Without these, the deduction is vulnerable on audit. The burden of proving entitlement to a deduction rests on the taxpayer.

Withholding tax on interest payments

Interest paid to a shareholder who is a resident individual is subject to a final withholding tax of 20% under Section 24(B)(1) of the NIRC, as amended. For a domestic corporate lender, Section 27(D)(1) imposes a final tax of 20% on interest from currency bank deposits and similar arrangements. The borrower, as withholding agent, must withhold and remit the tax.

Failure to withhold can result in assessment against the borrower, even if the interest was paid. This is a separate liability from the deductibility question.

Frequently asked questions

Is interest on a shareholder loan fully deductible?

Not automatically. It must be an ordinary and necessary business expense, paid on a valid indebtedness, at a reasonable rate, and supported by documentation. Related-party loans face stricter scrutiny.

What interest rate is considered reasonable for a shareholder loan?

Philippine law does not fix a single rate. The test is whether the rate is comparable to what an unrelated lender would charge under similar terms. A rate far above market may be disallowed.

Can the BIR treat shareholder loan interest as a dividend?

Yes. If the loan is not genuine or the terms are not arm's-length, the BIR may recharacterize the payment as a dividend or excessive compensation, which changes its tax treatment.

Practical takeaways

• Interest on a shareholder loan is deductible only if it is an ordinary and necessary business expense supported by a valid loan and actual payment.
• Related-party loans are scrutinized for arm's-length terms; above-market rates may be disallowed.
• A written loan agreement, board approval, and proof of business use are essential.
• The borrower must withhold the applicable final tax on interest paid to the shareholder.
• Failure to document or withhold can result in disallowance and assessment.
