Singapore has long positioned itself as an innovation hub in Asia, and its tax system reflects this ambition. Companies that invest in research and development, acquire intellectual property rights, or register patents and trademarks can access a range of tax deductions and incentives that significantly reduce the cost of IP creation and commercialisation.

This guide explains the key IP-related tax incentives available to Singapore companies in 2026 — including the enhanced R&D deductions under Section 14C and 14D of the Income Tax Act, the IP Development Incentive (IDI) under the Economic Development Board (EDB), and the writing-down allowances for intellectual property rights (IPRs).

Why Singapore Is Attractive for IP Holding

Beyond its competitive headline corporate tax rate of 17%, Singapore offers:

  • An extensive network of over 90 Avoidance of Double Taxation Agreements (DTAs), reducing withholding taxes on royalties received from overseas
  • No capital gains tax — gains from the disposal of IP assets are generally not taxable
  • Enhanced tax deductions for qualifying R&D and IP registration expenditure
  • The IP Development Incentive (IDI), which provides concessionary tax rates on qualifying IP income
  • Compliance with the OECD’s Base Erosion and Profit Shifting (BEPS) framework, including the modified nexus approach for IP regimes

Section 14C: Enhanced Deduction for R&D Expenditure

Under Section 14C of the Income Tax Act, companies carrying out qualifying research and development activities in Singapore may claim an enhanced tax deduction of 150% on qualifying R&D expenditure — compared to the standard 100% deduction.

What Qualifies

Qualifying R&D expenditure under Section 14C includes:

  • Staff costs (salaries, CPF, and other remuneration) for employees directly engaged in R&D activities in Singapore
  • Consumables used in R&D activities
  • Costs of R&D done in Singapore by external parties on behalf of the company (subject to conditions)

The R&D activities must be aimed at acquiring new knowledge, or creating new or significantly improved products, processes, devices, materials, or services. The IRAS R&D Tax Measures page provides detailed guidance on qualifying activities.

What Does Not Qualify

  • Market research, quality control, or routine testing
  • Social science or humanities research
  • R&D activities carried out wholly outside Singapore
  • Acquisition of existing technology for commercial use

Section 14D: R&D Expenditure Paid to Research Institutions

Where a Singapore company pays for R&D to be carried out by an approved research institution (such as A*STAR research institutes or Singapore universities), it may claim an enhanced deduction of 150% under Section 14D.

This makes co-investing in R&D with public research institutions particularly tax-efficient. The company must have the right to exploit the results of the R&D commercially to claim the enhanced deduction.

Writing-Down Allowances for Intellectual Property Rights (IPRs)

When a Singapore company acquires an intellectual property right — such as a patent, registered design, copyright, trade mark, know-how, or performance right — it may claim writing-down allowances (WDAs) on the cost of acquisition under Section 19B of the Income Tax Act.

How WDAs Work

The cost of the IPR is written down over a qualifying period chosen by the company: five, ten, or fifteen years. The company claims equal annual deductions over the chosen period, regardless of the useful life of the IP.

For example, if a company acquires a patent for S$300,000 and elects a five-year write-down period, it may claim S$60,000 per year as a tax deduction for five years.

Key Conditions

  • The IPR must be used for the purpose of producing income assessable to Singapore tax.
  • The IPR must have been created by or legally acquired from an unrelated party (related party acquisitions are subject to additional scrutiny).
  • The election of the write-down period is irrevocable once made.

IP Development Incentive (IDI)

For companies that derive significant income from qualifying IP — such as royalties, licence fees, and gains from IP disposals — the IP Development Incentive (IDI) administered by the Economic Development Board (EDB) provides a concessionary corporate tax rate on qualifying income.

Qualifying Income

The IDI covers income derived from:

  • Royalties and licence fees from qualifying IP assets
  • Gains from the disposal of qualifying IP assets
  • Income embedded in the sale price of products that incorporate the IP (under certain conditions)

Concessionary Rate

The IDI provides a concessionary tax rate of 5% or 10% on qualifying IP income, compared to the standard rate of 17%. The exact rate depends on the nature of the IP and the level of qualifying R&D activity carried out in Singapore.

Nexus Requirement

Consistent with the OECD’s modified nexus approach under BEPS Action 5, the IDI requires that qualifying income be linked to qualifying R&D expenditure incurred in Singapore. The greater the proportion of R&D carried out in Singapore, the greater the proportion of IP income eligible for the concessionary rate.

This means that companies seeking to benefit from the IDI must also invest genuinely in R&D activities in Singapore — not merely hold IP here for tax purposes.

Productivity and Innovation Credit (PIC) — Note on Discontinuation

The Productivity and Innovation Credit (PIC) scheme, which previously provided 400% tax deductions and cash payouts for qualifying innovation expenditure, was phased out for expenditure incurred after YA2018. Companies should not include PIC claims in current or future tax returns.

Practical Steps for IP Tax Planning in 2026

  • Keep detailed records of all R&D activities, including time sheets, project logs, and cost allocations — IRAS may request this documentation during an audit.
  • Segregate R&D expenditure from general operating expenditure in your accounts to make enhanced deduction claims easier to substantiate.
  • Before acquiring IP from a related party, ensure the transaction is at arm’s length and obtain appropriate transfer pricing documentation.
  • Consider applying for the IDI if your company is deriving or expects to derive significant royalty or IP licensing income — early engagement with EDB is recommended as IDI approval involves a detailed application process.
  • Elect your IPR write-down period carefully — the choice of five, ten, or fifteen years is irrevocable.
