Is Research and Development Spending Tax-Deductible? NIRC Section 34(I) and CREATE MORE's Enhanced Deduction

Research and development spending is deductible under NIRC Section 34(I) — a business can either treat qualifying R&D costs as an ordinary expense deducted in full the year they are paid, or elect to capitalize and amortize them over at least 60 months. Registered Business Enterprises that elect the CREATE Act’s Enhanced Deductions Regime, as expanded by the CREATE MORE Act, get a further 100% additional deduction for R&D tied to their registered activity — a meaningful incentive most eligible companies never claim simply because they don’t know the two rules stack.

This guide covers what Section 34(I) allows and excludes, the outright-deduction versus 60-month-amortization election, how CREATE MORE’s enhanced deduction layers on top for qualifying RBEs, and a worked example comparing the two paths for a mid-sized product-development cost.

What does NIRC Section 34(I) allow for R&D spending? #

Section 34(I)(1) gives a taxpayer the default option to treat research or development expenditures connected with its trade, business, or profession as ordinary and necessary expenses, deducted in full during the taxable year they are paid or incurred. This is the simplest path — no election, no capital account, no spreading the cost across future years.

The provision’s own text reads:

“A taxpayer may treat research or development expenditures which are paid or incurred by him during the taxable year in connection with his trade, business or profession as ordinary and necessary expenses which are not chargeable to capital account. The expenditures so treated shall be allowed as deduction during the taxable year when paid or incurred.” — NIRC Section 34(I)(1)

Not every R&D-labeled cost qualifies, though. Section 34(I) carves out two specific exclusions: costs for the acquisition or improvement of land, and any expenditure incurred to ascertain the existence, location, extent, or quality of a natural deposit — oil, gas, or another mineral — including deposits in commercially marketable quantities. It also does not duplicate a deduction already available for the same expenditure under another provision of the Tax Code for the same taxable year; a cost that is properly deductible elsewhere is not deducted twice by relabeling it R&D.

When can R&D costs be amortized instead of expensed outright? #

Section 34(I)(2) gives a taxpayer an alternative: elect to treat qualifying R&D expenditures as deferred expenses and amortize them ratably over a period of not less than 60 months, rather than deducting the full amount in the year paid. This matters for costs that are chargeable to a capital account (because they produce a benefit lasting beyond one year) but are not otherwise subject to depreciation or depletion — precisely the kind of cost that outright expensing under paragraph (1) would not otherwise reach as cleanly.

Two mechanical rules govern the election:

• Amortization begins with the month the taxpayer first realizes benefits from the expenditure — not necessarily the month the cost was incurred, since a research project may not produce a usable benefit until later.
• Once a taxpayer elects the deferred-expense treatment, that election applies consistently to all of its qualifying R&D expenditures unless the Commissioner approves a change to a different method — a taxpayer cannot pick and choose outright expensing for some projects and 60-month amortization for others within the same election period without approval.

In practice, most ordinary and necessary R&D costs — salaries of research staff, materials consumed in testing, prototype costs — are simply expensed outright under paragraph (1), since that produces the earlier deduction. The amortization election under paragraph (2) becomes relevant mainly for larger, capital-account-adjacent R&D outlays where a business wants to match the deduction to when the resulting benefit is actually realized, or where accounting policy already treats the cost as a deferred asset.

How does CREATE MORE’s Enhanced Deductions Regime add to this? #

For a Registered Business Enterprise (RBE) that elects the Enhanced Deductions Regime (EDR) — available under the original CREATE Act, Republic Act No. 11534, and carried forward and expanded by the CREATE MORE Act, Republic Act No. 12066 — research and development expense qualifies for a 100% additional deduction on top of whatever is already deductible under Section 34(I). This is an incentive layered on top of the regular Tax Code rule, not a replacement for it, and it is restricted to RBEs that have registered a project or activity with an Investment Promotion Agency (IPA) and chosen EDR over the alternative Special Corporate Income Tax (SCIT) option.

The Enhanced Deductions Regime bundles R&D together with several other enhanced items available to a qualifying RBE:

To claim the enhanced R&D deduction, the expenditure generally has to be directly related to the RBE’s registered project or activity and incurred domestically — R&D spent on an unregistered product line, or research conducted and paid for entirely outside the Philippines, does not qualify for the additional layer even if the base Section 34(I) deduction still applies to it. As with the other enhanced deductions, this additional amount is computed only after gross income and ordinary operating expenses have already been determined — it is an extra deduction on top of, not a substitute for, the regular Section 34(I) treatment.

A company that has not registered with an IPA, or that registered but elected SCIT instead of EDR, does not lose the Section 34(I) deduction itself — it simply does not get the additional 100% RBE layer, since that piece is an incentive tied to registration and regime election, not a general Tax Code rule available to every taxpayer.

Worked example: outright deduction vs. RBE enhanced deduction #

A locally registered electronics assembler spends ₱2,000,000 in a taxable year developing a new circuit design — engineering salaries, prototype materials, and testing costs — all incurred and paid domestically and directly tied to its manufacturing operations. Compare two scenarios:

The ordinary corporation deducts the full ₱2,000,000 once, exactly as Section 34(I)(1) provides. The RBE, because it registered the assembly project with an IPA and elected the Enhanced Deductions Regime, deducts the same ₱2,000,000 under Section 34(I) and then claims a further ₱2,000,000 additional deduction under CREATE MORE’s enhanced R&D item — doubling the tax benefit of the identical cash outlay, without changing what was actually spent on the research itself.

Summary #

NIRC Section 34(I) gives every taxpayer, regardless of registration status, a choice for R&D spending: deduct it outright as an ordinary expense in the year paid, or elect to amortize it over at least 60 months once benefits are realized — excluding land costs and natural-deposit exploration costs either way. A Registered Business Enterprise that elects CREATE MORE’s Enhanced Deductions Regime can claim a further 100% additional deduction for R&D directly tied to its registered activity, stacking on top of the base Section 34(I) deduction rather than replacing it. A company weighing whether IPA registration and EDR election are worth pursuing should factor in this R&D layer alongside the other enhanced items — labor, training, power, and depreciation — since together they can substantially lower the effective cost of an R&D-heavy registered project.
