Generally Not Taxable

  • Selling shares held as long-term investments
  • Selling a residential property (capital asset)
  • Selling cryptocurrency held as an investment
  • Foreign-sourced capital gains remitted to Singapore
  • Gains from fixed deposits and bonds held to maturity

May Be Reclassified as Income

  • Frequent, systematic share trading (high volume)
  • Short holding periods with leveraged borrowing
  • Property flipping as a primary occupation
  • Crypto trading activity run as a business
  • Using sophisticated hedging strategies on positions

How IRAS Determines Capital vs. Income

IRAS weighs the "badges of trade" holistically. No single factor is decisive, but the more that apply, the greater the risk of reclassification.

Frequency

How often you buy and sell — more transactions suggest a trading business.

Holding period

Very short holds (days or weeks) point toward a trading intent.

Financing

Borrowing to fund purchases signals a profit motive beyond passive investment.

Repetition

Repeated similar transactions over time indicate a systematic pattern.

Primary occupation

If trading is your main job or generates most of your income, IRAS takes note.

Organisation

Dedicated staff, offices, or trading infrastructure all indicate a business.

Summary

Singapore imposes no capital gains tax — this tool explains the rules, calculates property stamp duty, and estimates tax when frequent trading income is reclassified.

How it works

  1. Select a scenario: property stamp duty, trading income tax, or a general CGT rules explainer.
  2. For stamp duty: enter the property value and buyer profile (Singapore citizen, PR, or foreigner).
  3. BSD is calculated on the first purchase price bracket; ABSD is added based on residency and number of properties owned.
  4. For trading income: enter your annual trading profit and other income; the tool applies 2024 IRAS personal tax rates.
  5. Results show total stamp duty or income tax owed, the effective rate, and a line-by-line breakdown.
  6. A plain-English rules summary explains when IRAS is likely to reclassify gains as income.

Use cases

  • Verify that a long-term share sale in Singapore is free of capital gains tax.
  • Calculate BSD and ABSD before purchasing a residential property in Singapore.
  • Estimate income tax exposure if you trade stocks frequently and IRAS treats gains as business income.
  • Understand the difference between investment income (not taxable) and trading income (taxable) under IRAS rules.
  • Plan property purchases for permanent residents buying a second home.
  • Model stamp duty costs for foreign buyers acquiring Singapore real estate.
  • Assess the tax impact of selling a property within the Seller's Stamp Duty (SSD) window.
  • Compare after-tax returns on Singapore assets versus jurisdictions that impose CGT.
