If your Singapore company has under-declared income, over-claimed deductions, or missed a tax filing obligation, you have a window to come clean — and pay materially less than if IRAS finds the error first. IRAS’ Voluntary Disclosure Programme (VDP) allows companies to disclose errors in corporate income tax, GST, withholding tax, and stamp duty before an audit begins, and in return receive a reduced penalty regime that has saved many SMEs from six-figure surcharges.
This article explains how the VDP works in 2026, who qualifies for the reduced penalty rates, what counts as a “qualifying” voluntary disclosure, how to make the disclosure, and the practical decisions directors should make before deciding whether to disclose or to wait.
Why the VDP Matters
Singapore’s tax regime is self-assessment. Companies file Form C-S or Form C with their corporate income tax return, file GST Form F5, and pay withholding tax (WHT) at source. Errors happen — misclassified expenses, omitted income, missed WHT on payments to non-residents, missed stamp duty on share transfers. When IRAS later discovers the error during a desk audit, field audit, or data-matching exercise, the penalty regime in section 95 of the Income Tax Act and section 59 of the GST Act bites hard: up to 200% of the tax undercharged plus interest.
The VDP reduces those penalties dramatically if the disclosure is voluntary, timely, and complete.
The Three Tiers of VDP Treatment
Tier 1 — Voluntary disclosure within the “grace period”
For most taxes, IRAS treats the disclosure as fully voluntary if it is made within 1 year of the statutory filing deadline. Penalties for disclosures in this period are typically 5% per annum of the tax undercharged (no flat penalty). For GST, the position is similar but tied to the GST F5 return period.
Tier 2 — Voluntary disclosure after the grace period but before IRAS contacts the taxpayer
Beyond the grace period but before IRAS opens an audit, the VDP penalty is generally 5% flat plus 5% per annum. This is materially below the 100%-200% normal penalty regime.
Tier 3 — Disclosure after IRAS has commenced an audit or investigation
Once IRAS has contacted the company about a specific period or transaction, the VDP penalty rates no longer apply for that disclosure. The full statutory penalty regime applies, subject to IRAS’ discretion to reduce the penalty if the taxpayer cooperates.
The lesson: the earlier the disclosure, the lower the penalty. Directors who suspect an error should not wait for IRAS to come knocking.
What Counts as a “Voluntary” Disclosure?
IRAS’ position is that a disclosure is voluntary if:
- It is made before IRAS commences an audit, investigation, or inquiry into the relevant period or transaction;
- It is complete and accurate — including all related entries (e.g. if you disclose under-declared revenue, you must also disclose the matching expenses);
- The taxpayer cooperates fully during the resolution of the disclosure, including providing supporting documents on request;
- The tax liability and any imposed penalty are paid in full on assessment (or under an approved payment plan).
If IRAS has already issued an audit query letter for the period in question, a disclosure of the same error within that period is not voluntary. But a disclosure of an unrelated error in a different period can still qualify.
Common Situations Where the VDP Is Used
- Under-declared revenue: rebates, commissions, or related-party transactions omitted from the corporate tax return.
- Over-claimed deductions: capital expenditure misclassified as revenue, private expenses passed through, or pre-trade expenses claimed before the qualifying date under section 14U ITA.
- Missed withholding tax: WHT under section 45 ITA on royalties, interest, or technical service fees paid to non-residents. This is one of the most common VDP cases for SMEs that don’t realise WHT applies to overseas vendor payments.
- GST errors: under-declared output tax (especially on barter transactions or imported services under the reverse charge), over-claimed input tax, or missed GST registration past the S$1 million threshold.
- Stamp duty: missed stamping of share transfers within the 14-day window, or under-stamping of property transfers and leases.
- Section 24 ITA related-party transactions: post-event review showing intra-group prices were not at arm’s length.
How to Make a Disclosure
For corporate income tax, the disclosure is made through the IRAS myTax Portal using the “VDP” submission category, or by letter to the assessing branch. The submission should include:
- A clear statement that the disclosure is being made under the VDP.
- The year(s) of assessment or accounting periods affected.
- A description of the error and how it arose.
- Computation of the additional tax liability for each affected period.
- Supporting workings and documents (revised P&L, journal entries, contracts, invoices).
- An undertaking to settle the assessment in full.
For GST, the disclosure is made via the GST F7 (Disclosure of Errors on GST Return). For WHT, the disclosure is made via the S45 amendment route in myTax Portal. For stamp duty, the disclosure is made via the IRAS e-Stamping portal with a remission application under section 73 of the Stamp Duties Act.
VDP and Section 33 GAAR — A Word of Caution
The VDP does not apply to tax avoidance arrangements caught by section 33 ITA (the General Anti-Avoidance Rule) or to tax evasion offences under section 96 ITA. If the error involves dishonest intent, the disclosure may still attract criminal penalties, although IRAS may treat the voluntary disclosure as a mitigating factor in sentencing. Directors should obtain legal advice before making a VDP submission in cases involving deliberate misstatement.
Should You Disclose? A Decision Framework
Before making a VDP submission, directors should weigh:
- The size of the error. If under S$2,000-S$5,000 across all years, IRAS may not consider it material and the cost of disclosure may outweigh the saving.
- The likelihood of detection. IRAS data-matching across CPF, SSIC, ACRA, customs, and bank account data is increasingly sophisticated. Errors in related-party transactions and WHT are particularly easy to detect.
- The director liability angle. Section 95 ITA directors’ personal liability provisions can attach to deliberate or negligent under-declarations. Voluntary disclosure mitigates director exposure.
- The audit trail. If the company is about to be sold or financed, the buyer/lender’s tax due diligence will surface the issue. Disclosing first is almost always cheaper than disclosing in response to a buyer’s discovery.
What Happens After the Disclosure?
IRAS will review the submission, may request supporting documents, and will issue a notice of additional assessment. The reduced VDP penalty is computed on the additional tax. Payment is due within 1 month of the notice unless a payment plan is approved. After payment, the matter is closed for the disclosed years — but the disclosure does not insulate the company from audit of other years.
If IRAS disagrees with the computation or the characterisation of the error, the normal objection and appeal process under section 76 ITA applies — VDP does not waive appeal rights.
Statutory Provisions and References
IRAS’ published guidance on the VDP is available at iras.gov.sg (search “Voluntary Disclosure Programme”). The penalty regimes are at section 95 of the Income Tax Act 1947 and section 59 of the GST Act 1993, both at sso.agc.gov.sg. Section 33 GAAR is at section 33 of the Income Tax Act 1947.
