Singapore CPF Top-Up Tax Relief Guide 2026: Save Tax with CPF Contributions
Last updated: July 2026 | SeaMoneyTips
What Is CPF Top-Up Tax Relief in Singapore?
CPF top-up tax relief allows Singapore residents to reduce their taxable income by making voluntary contributions to their CPF accounts. When you top up your CPF Ordinary Account (OA) or Special Account (SA), you can claim a tax relief of up to SGD 8,000 per year under Section 77A of the Income Tax Act.
This is one of the most effective ways to lower your income tax while simultaneously building your retirement savings. The relief applies to top-ups made to your own CPF accounts as well as top-ups made to your spouse, parents, grandparents, or siblings who are not earning more than SGD 2,000 per month.
Types of CPF Top-Up Tax Relief
There are several types of CPF top-ups that qualify for tax relief in Singapore:
Cash Top-Up to OA or SA (Section 77A)
This is the most common type of CPF top-up tax relief. When you make a voluntary cash top-up to your own OA or SA, you can claim up to SGD 8,000 in tax relief. The top-up must be made in cash (not via salary transfer or other CPF contributions).
Key points about Section 77A relief:
- Maximum relief: SGD 8,000 per year for top-ups to your own accounts
- Additional relief: Up to SGD 8,000 for top-ups to family members’ accounts
- Total maximum relief: Up to SGD 16,000 per year (SGD 8,000 own + SGD 8,000 family)
- Eligible accounts: OA and SA (not MediSave Account)
- Minimum age: None
MediSave Top-Up Relief (Section 77B)
Separately, you can also claim tax relief for voluntary contributions to your MediSave Account. The maximum relief for MediSave top-ups is SGD 8,000 per year. This is in addition to the Section 77A relief.
- Maximum relief: SGD 8,000 per year
- Eligible accounts: MediSave Account only
- Can be claimed alongside Section 77A relief
Voluntary Contribution (VC) to All Three Accounts
You can also make a voluntary contribution that is distributed across all three CPF accounts (OA, SA, and MediSave) based on the current allocation ratios. This type of contribution qualifies for tax relief under Section 77A, subject to the same SGD 8,000 cap.
How Much Tax Can You Save with CPF Top-Up?
The amount of tax you save depends on your marginal tax rate. Here is a breakdown of potential savings:
| Annual Income (SGD) | Marginal Tax Rate | Tax Saved (SGD 8,000 Top-Up) | Tax Saved (SGD 16,000 Top-Up) |
|---|---|---|---|
| 20,001 – 30,000 | 2% | SGD 160 | SGD 320 |
| 30,001 – 40,000 | 3.5% | SGD 280 | SGD 560 |
| 40,001 – 80,000 | 7% | SGD 560 | SGD 1,120 |
| 80,001 – 120,000 | 11.5% | SGD 920 | SGD 1,840 |
| 120,001 – 160,000 | 15% | SGD 1,200 | SGD 2,400 |
| 160,001 – 200,000 | 18% | SGD 1,440 | SGD 2,880 |
| 200,001 – 240,000 | 19% | SGD 1,520 | SGD 3,040 |
| 240,001 – 280,000 | 19.5% | SGD 1,560 | SGD 3,120 |
| 280,001 – 320,000 | 20% | SGD 1,600 | SGD 3,200 |
| 320,001+ | 22% | SGD 1,760 | SGD 3,520 |
For example, if you earn SGD 100,000 per year and top up SGD 8,000 to your SA, you save SGD 920 in tax. If you top up the full SGD 16,000 (SGD 8,000 to your own accounts and SGD 8,000 to a family member’s account), you save SGD 1,840.
How to Claim CPF Top-Up Tax Relief
Claiming your CPF top-up tax relief is straightforward. Here is the step-by-step process:
- Make Your CPF Top-Up – Log in to the CPF website or app and make a voluntary cash top-up to your OA, SA, or MediSave account.
- Check Your CPF Statement – Verify that the top-up appears in your CPF transaction history. You will need this as proof.
- File Your Tax Return – During tax filing (February to April), declare the CPF top-up amount under the “Reliefs” section of your tax return.
- Select the Correct Relief Type – Choose Section 77A for OA/SA top-ups or Section 77B for MediSave top-ups.
- Enter the Amount – Input the exact amount you topped up (up to SGD 8,000 per relief type).
- Submit and Verify – Submit your tax return and verify that the relief is reflected in your Notice of Assessment (NOA).
CPF Top-Up Tax Relief for Family Members
You can also claim tax relief when you top up your family members’ CPF accounts. The same SGD 8,000 cap applies, but there are additional eligibility criteria:
| Family Member | Eligibility Requirement | Relief Cap |
|---|---|---|
| Spouse | Not earning more than SGD 2,000/month | SGD 8,000 (combined with own relief) |
| Parent | Not earning more than SGD 2,000/month | SGD 8,000 (combined with own relief) |
| Grandparent | Not earning more than SGD 2,000/month | SGD 8,000 (combined with own relief) |
| Sibling | Not earning more than SGD 2,000/month, disabled or above 55 | SGD 8,000 (combined with own relief) |
The total relief for top-ups to family members is capped at SGD 8,000 regardless of how many family members you top up. For example, if you top up SGD 5,000 to your parent and SGD 5,000 to your spouse, your total family top-up relief is SGD 8,000 (not SGD 10,000).
CPF Top-Up vs Other Tax Reliefs
Here is how CPF top-up tax relief compares with other common tax reliefs in Singapore:
| Tax Relief | Maximum Amount | Requirement | Benefit |
|---|---|---|---|
| CPF Top-Up (Section 77A) | SGD 8,000 | Cash top-up to OA/SA | Retirement savings + tax relief |
| MediSave Top-Up (Section 77B) | SGD 8,000 | Cash top-up to MediSave | Healthcare savings + tax relief |
| CPF Special Account Top-Up | Included in 77A | Part of Section 77A | Higher CPF interest rate |
| Parent Relief | SGD 9,000 | Parents above 55 with income < SGD 4,000/month | Support for elderly parents |
| NSman Relief | SGD 1,500 | Completed NS | National service contribution |
| Course Fees Relief | SGD 5,500 | Approved courses | Lifelong learning |
The advantage of CPF top-up relief is that it directly benefits your retirement savings. Unlike other reliefs that are pure deductions, the money you use for CPF top-ups continues to earn CPF interest rates (up to 4% per annum for SA and MediSave).
Common Mistakes to Avoid
When claiming CPF top-up tax relief, avoid these common mistakes:
- Forgetting to Claim – CPF top-up relief is not automatic. You must declare it during tax filing.
- Exceeding the Cap – The relief is capped at SGD 8,000 per year for each type. Top-ups beyond this amount do not generate additional tax relief.
- Confusing Relief Types – Section 77A (OA/SA) and Section 77B (MediSave) are separate reliefs. You can claim both, but each has its own SGD 8,000 cap.
- Not Checking Family Eligibility – Your family member must not earn more than SGD 2,000 per month to qualify for the top-up relief.
- Mixing Up Voluntary and Mandatory Contributions – Only voluntary cash top-ups qualify for relief. Employer CPF contributions and mandatory employee contributions do not count.
- Claiming for the Wrong Year – The top-up must be made in the same calendar year as the tax filing year. Top-ups made in January 2026 can only be claimed for the Year of Assessment 2026 (filing in 2027).
CPF Interest Rates on Top-Ups
When you top up your CPF accounts, the money earns CPF interest rates. This is an additional benefit beyond the tax relief:
| Account | Base Interest Rate | Extra Interest (First SGD 60,000) | Effective Rate |
|---|---|---|---|
| OA | 2.5% per annum | 1% (for first SGD 20,000 in OA) | Up to 3.5% |
| SA | 4% per annum | 1% (for first SGD 30,000 in SA) | Up to 5% |
| MediSave | 4% per annum | 1% (for first SGD 30,000 in MA) | Up to 5% |
The extra interest applies to the first SGD 60,000 of combined CPF balances (capped at SGD 20,000 for OA). This means topping up your SA can earn up to 5% per annum – one of the risk-free returns available in Singapore.

Frequently Asked Questions
How do I top up my CPF account for tax relief?
You can top up your CPF account via the CPF website, CPF app, ATM, or at any SingPost branch. Log in with your SingPass, select the amount and account (OA, SA, or MediSave), and make the payment. The top-up will appear in your CPF transaction history for tax filing purposes.
Can I claim CPF top-up tax relief for my parents?
Yes, you can claim tax relief for top-ups to your parents’ CPF accounts, provided they are not earning more than SGD 2,000 per month. The relief for family top-ups is combined with your own relief under the same SGD 8,000 cap for Section 77A.
Is CPF top-up tax relief the same as CPF SA top-up relief?
Yes, CPF SA top-up relief falls under Section 77A of the Income Tax Act. When you make a voluntary cash top-up to your Special Account (SA), you can claim the same Section 77A relief with the same SGD 8,000 cap. SA top-ups also earn the higher SA interest rate of 4% per annum.
What is the deadline for CPF top-up to claim tax relief?
The top-up must be made before the end of the calendar year (31 December) to claim tax relief for that year. For example, top-ups made by 31 December 2026 can be claimed when filing taxes for the Year of Assessment 2026 (due by 18 April 2027). There is no specific monthly deadline within the year.
Can I top up my CPF OA for tax relief?
Yes, voluntary cash top-ups to your Ordinary Account (OA) qualify for Section 77A tax relief up to SGD 8,000 per year. However, SA top-ups are generally more beneficial because the SA earns a higher interest rate of 4% compared to the OA’s 2.5%.
Does employer CPF contribution count for tax relief?
No, employer CPF contributions do not qualify for Section 77A or 77B tax relief. Only voluntary cash top-ups that you make directly to your CPF accounts qualify for these specific reliefs. Employer contributions are already tax-exempt and do not need additional relief.
