Can a company deduct money it puts into an employee retirement fund?

Yes. NIRC Section 34(J) allows an employer that establishes or maintains a pension trust to deduct contributions to it, on top of ordinary business expenses. The current year's normal cost — the actuarially computed cost of benefits accruing that year — is deducted in full in the year paid, the same as any other business expense under Section 34(A)(1).

Does the pension trust have to be BIR-approved before contributions are deductible?

The Section 34(J) deduction itself does not require BIR approval of the plan — it applies to a pension trust maintained to pay reasonable pensions to employees. In practice, however, employers seek a BIR Certificate of Qualification under Revenue Regulations No. 15-2025 anyway, because that certificate is what makes the trust fund's own investment income, and the retirement benefits employees eventually receive, exempt from income tax as well. Without it, the employer's contribution deduction can still apply, but the trust's earnings and the employees' payouts lose their separate tax exemptions.

What happens if an employer contributes more than the actuarially determined normal cost and past service cost?

Only a reasonable amount tied to the plan's actuarial funding requirements is deductible under Section 34(J). A contribution in excess of what the plan's actuary certifies as necessary to fund current and past service liabilities is not automatically deductible simply because it was paid into the trust — the BIR can disallow the excess as unreasonable, since the deduction is meant to fund an actual pension liability, not to shelter income.

Can a Company Deduct Contributions to Its Employee Pension Trust? NIRC Section 34(J) Explained

Q: What is the difference between normal cost and past service cost?

Normal cost is the cost of retirement benefits accruing for the current year's service and is fully deductible in the year paid. Past service cost is a lump sum an employer transfers into the trust to fund benefits for service employees already rendered before the plan existed or was amended — because it covers multiple prior years at once, NIRC Section 34(J) does not let it be deducted immediately; it must be spread in equal parts over 10 consecutive years starting the year the transfer is made.

Q: Can an employer deduct the full past service cost in the year it funds the plan?

No. Even if an employer transfers the entire past service cost into the trust in a single payment, NIRC Section 34(J) requires that amount to be apportioned in equal parts over 10 consecutive years beginning with the year the transfer is made — the employer cannot accelerate the deduction into fewer years, and cannot deduct any part of it twice.

An employer that sets up or maintains a pension trust for its employees can deduct its contributions to that trust under NIRC Section 34(J) — but not always in full, in the year paid. The current year’s normal cost is deducted outright, same as any other business expense, while a lump-sum past service cost transferred in to cover benefits for years already worked before the plan existed must instead be spread in equal parts over 10 consecutive years. Getting that split wrong is a common payroll-accounting error.

This guide covers what Section 34(J) actually allows, the normal cost vs. past service cost distinction that drives the 10-year amortization rule, how this interacts with BIR-qualified plan status under Revenue Regulations No. 15-2025, and a worked example of an employer funding a new plan’s past service liability.

What does NIRC Section 34(J) actually allow an employer to deduct? #

Section 34(J) lets an employer deduct amounts paid into a pension trust maintained to provide reasonable pensions for its employees, on top of the ordinary business-expense deduction it already claims for the trust’s normal cost. The provision is deliberately narrow: it is not a general deduction for any retirement-related spending, but a specific rule for funding a trust — meaning a formal fund, typically held by a trustee or funded through an insurance contract, set aside exclusively for paying employee pensions.

The text of the provision itself reads:

“An employer establishing or maintaining a pension trust to provide for the payment of reasonable pensions to his employees shall be allowed as a deduction (in addition to the contributions to such trust during the taxable year to cover the pension liability accruing during the year, allowed as a deduction under Subsection (A) (1) of this Section) a reasonable amount transferred or paid into such trust during the taxable year in excess of such contributions, but only if such amount (1) has not theretofore been allowed as a deduction, and (2) is apportioned in equal parts over a period of ten (10) consecutive years beginning with the year in which the transfer or payment is made.” — NIRC Section 34(J)

Two things follow directly from that text. First, the year’s ordinary contribution to cover the pension liability accruing that year is deducted separately, under the general business-expense rule in Section 34(A)(1) — Section 34(J) does not touch that part at all. Second, Section 34(J) itself only governs the excess amount transferred beyond that current-year contribution, and forces that excess to be spread over exactly 10 years, never allowed twice, and never accelerated.

What is the difference between normal cost and past service cost? #

Actuaries who fund pension plans split what an employer owes the trust into two categories, and NIRC Section 34(J) treats each one differently for deduction purposes. Getting this distinction right determines whether an employer’s contribution is fully deductible this year or must be recognized over a decade.

Normal cost is the actuarially computed cost of retirement benefits accruing for the current year of employee service. Because it relates only to the year in which it is paid, it is deducted in full that year under Section 34(A)(1) — the same treatment as salaries, rent, or any other ordinary and necessary business expense.
Past service cost is a separate, typically much larger, lump-sum amount an employer transfers into the trust to fund pension benefits for service employees already rendered in earlier years — most commonly when a company first establishes a plan and wants to credit employees for years already worked, or when it later increases benefit levels retroactively. Because this amount effectively funds many prior years of accrued liability all at once, Section 34(J) does not allow it to be expensed immediately; it must instead be apportioned in equal parts over 10 consecutive years, starting with the year the transfer is made.

An employer that pays only normal cost each year has nothing to amortize — the full amount is simply deducted annually as it is paid. The 10-year rule only bites when a company is catching up on funding for years of service that predate the trust’s creation or a benefit increase.

Does the plan need to be BIR-qualified for the deduction to apply? #

The Section 34(J) deduction applies to a pension trust maintained to pay reasonable pensions, without itself requiring a separate BIR approval — but employers pursue BIR qualification anyway, because it unlocks two further exemptions that Section 34(J) does not provide on its own. A BIR-qualified plan, since Revenue Regulations No. 15-2025 replaced the BIR’s 1968-era approval rules under Republic Act No. 4917, requires the employer to secure a Certificate of Qualification for the retirement plan.

Qualification matters because it is what makes (1) the trust fund’s own investment income, and (2) the retirement benefits employees eventually receive, exempt from income tax and withholding tax in their own right — separate questions from whether the employer can deduct its contributions. An employer can generally still deduct reasonable, actuarially supported contributions to an unqualified trust under Section 34(J), but without qualification, the fund’s earnings are taxable as they accrue and the payouts employees eventually receive lose the exemption available under NIRC Section 32(B)(6)(a). In practice, that makes BIR qualification the more valuable prize, and most employers pursue both tracks together rather than relying on the Section 34(J) deduction alone.

Worked example: funding a new plan’s past service cost #

A mid-sized manufacturing company with 80 employees establishes a formal, trusteed retirement plan for the first time in 2026 and wants to credit staff for years already served before the plan existed. Its actuary certifies the following for the plan’s first year:

Item	Amount	Tax treatment
Normal cost (current year’s accruing benefits)	₱1,200,000	Deducted in full in 2026 under Sec. 34(A)(1)
Past service cost (funding prior years of service)	₱5,000,000	Apportioned over 10 years under Sec. 34(J)
Annual past service cost deduction (₱5,000,000 ÷ 10)	₱500,000	Deducted each year from 2026 through 2035
Total deductible in 2026	₱1,700,000	₱1,200,000 normal cost + ₱500,000 first-year past service tranche

Even though the company transferred the full ₱5,000,000 past service amount into the trust in a single 2026 payment, it can only claim ₱500,000 of that transfer as a deduction in 2026 — the remaining ₱4,500,000 is recognized at ₱500,000 per year through 2035. The ₱1,200,000 normal cost, by contrast, is not subject to any spreading rule and is deducted in full the same year it is paid, exactly as it would be for any other current business expense.

Summary #

NIRC Section 34(J) lets an employer deduct contributions to an employee pension trust, but splits the treatment: normal cost — the actuarial cost of the current year’s accruing benefits — is deducted in full each year under Section 34(A)(1), while any past service cost funding prior years of service must be apportioned in equal parts over 10 consecutive years and can never be deducted twice. Section 34(J) qualification is separate from BIR plan qualification under Revenue Regulations No. 15-2025, which instead governs whether the trust’s investment income and employees’ eventual retirement payouts are tax-exempt. Employers setting up or funding a plan for the first time should have their actuary clearly separate normal cost from past service cost before claiming either deduction, since misclassifying a lump-sum past service payment as fully deductible current-year cost is a common — and easily assessed — payroll-accounting error.
