What is Estimated Chargeable Income (ECI) and how to File it?
Estimated Chargeable Income (ECI) is your company’s taxable profit, calculated after deducting allowable business expenses, for a specified Year of Assessment (YA).
To ensure accurate filing and avoid costly errors, businesses can engage Plutus Services for expert guidance in ECI calculation, submission, and overall tax compliance.
Who Must File ECI by When?
All companies must file their ECI within 3 months of the end of their financial year
Waiver available if:
- Company revenue ≤ S$5 million, and
- ECI is nil for the YA (before exemptions)
Note: Some entities, such as foreign universities or REITs, are automatically exempt .
Why Early Filing Matters
- Qualifies your company for installment payment options.
- File in Month 1 → up to 10 instalments
- Month 2 → up to 8 instalments
- Month 3 → up to 6 instalments
- File in Month 1 → up to 10 instalments
- Avoid penalties—late filing may lead to assessment based on prior years and loss of instalment benefits.
How to File for ECI?
File ECI via myTax Portal—requires CorpPass approval. If actual taxable income changes post-filing, you must submit a revision online
💵 Payment and Assessments
- You’ll receive an Estimated Notice of Assessment(s) once IRAS processes your filing
- Payment due within 1 month, unless instalment plan applies. Refunds or additional payments automatically processed based on final tax return .

2️⃣ Profit and Loss Summary (before tax)
| Description | Amount (S$) |
| Revenue / Turnover | [e.g. 500,000] |

3️⃣ Adjustments to Net Profit
(Add back non-deductible expenses / remove non-taxable income)
| Adjustment Description | Add / (Less) | Amount (S$) |
| Depreciation (non-deductible) | Add | [10,000] |
| Non-tax deductible entertainment | Add | [2,000] |

| Non-taxable income (e.g. dividend from subsidiary) | Less | [2,000] |
= Estimated Chargeable Income (ECI)
ECI = Net Profit + Additions – Deductions
ECI = 155,000 + (10,000 + 2,000 + 3,000) – (8,000 + 5,000 + 2,000) = 155,000 + 15,000 – 15,000 = S$155,000
