If you are under 55 and topping up your CPF for tax relief, fund your Special Account first. Both a cash top-up to your MediSave Account and to your Special Account earn the same 4% floor rate, and both draw from the same $8,000 self tax relief cap in 2026. The difference is what the money does afterwards: SA savings can later move into your Retirement Account and turn into a lifelong CPF LIFE payout, while MA savings are locked to healthcare and stop accepting top-ups the moment you hit the $79,000 Basic Healthcare Sum. The only times MA goes first are when you are self-employed offsetting MediSave payable, or you are already near the Full Retirement Sum and your SA top-up room has run out. This guide walks through the rules, the limits, and the decision for 2026 numbers.
For a salaried worker under 55 who wants the $8,000 tax relief and the highest long-term return, the Special Account top-up wins. The interest is identical at 4%, but an SA top-up is on the path to a Retirement Account and a CPF LIFE payout, whereas a MediSave top-up is ring-fenced for medical bills and insurance premiums and caps out at the Basic Healthcare Sum.
The two routes are not mutually exclusive. The relief is shared, so any dollar of relief you use on MA is a dollar you cannot use on SA. You get to split a single $8,000 self cap across both accounts however you like, plus a separate $8,000 for topping up family members.
| Feature | MediSave Account (MA) | Special Account (SA) |
|---|---|---|
| Interest rate (floor) | 4.0% p.a. | 4.0% p.a. |
| Tax relief | Shares the $8,000 self cap | Shares the $8,000 self cap |
| 2026 ceiling | $79,000 Basic Healthcare Sum | Up to Full Retirement Sum ($220,400) |
| What the money is for | Hospital bills, MediShield/IP premiums | Becomes RA, funds CPF LIFE payout |
| Can it become retirement income | No, healthcare only | Yes, via Retirement Account |
| Reversible | No | No |
The Special, MediSave and Retirement Accounts all sit under the same interest formula, often called the SMRA rate. The Government has extended the 4% floor on all SMRA monies through 31 December 2026, so for the first half of 2026 both the SA and MA pay 4.0% per annum, against 2.5% for the Ordinary Account.
On top of that base, members below 55 earn an extra 1% on the first $60,000 of combined CPF balances, with at most $20,000 of that counted from the Ordinary Account. The extra interest on OA balances is credited into the SA, not the OA. So the early dollars in your SA or MA can effectively earn 5% while your combined balance is still small. Because the base rate is the same on both accounts, interest alone does not separate the two, which is why the decision comes down to liquidity, limits and purpose. The CPF interest rates guide breaks down exactly how the extra-interest tiers stack.
Cash top-ups under the Retirement Sum Topping-Up scheme (to your SA or RA) and voluntary cash top-ups to your MediSave Account both qualify for CPF Cash Top-up Relief. The relief is capped at $8,000 for top-ups to your own accounts and a further $8,000 for top-ups to your loved ones' accounts, giving a maximum of $16,000 a year. A top-up you make in 2026 is claimed in the 2027 Year of Assessment (YA 2026 covers income earned in 2025).
The detail that trips people up: the $8,000 self cap is shared across your SA/RA and MA top-ups combined. Put $8,000 into your SA and you have used the whole cap; you can still pay more into MA, but the extra earns no further relief. Two more conditions matter. Relief on SA/RA top-ups is granted only up to the current year's Full Retirement Sum of $220,400, so once your SA balance plus mandatory contributions are projected to hit the FRS, the top-up room for relief closes. And from 2025, cash top-ups that qualify for the Matched Retirement Savings Scheme no longer attract tax relief.
Relief goes to the giver, not the recipient. If you top up your parent's MediSave, you claim the relief, not them. And the whole thing sits under the $80,000 overall personal income tax relief ceiling, so if you are already near that limit, a top-up may give you no tax benefit at all. To see how a top-up changes your actual bill, run your figures through the income tax calculator before committing.
Take Priya, 34, with $50,000 in her MediSave Account at the start of 2026. The Basic Healthcare Sum is $79,000, so her MA can still take $29,000 before it is full. She also has plenty of room in her Special Account, well below the $220,400 Full Retirement Sum. She has $8,000 of cash she wants to put to work, and she is in the 11.5% marginal tax bracket.
If Priya puts the full $8,000 into MA, she uses her entire self relief cap, cuts her chargeable income by $8,000, and saves about $920 in tax. Her MA grows at 4%, but the money can only ever pay healthcare bills and insurance premiums. If she instead puts the same $8,000 into her SA, she gets the identical $920 tax saving and the identical 4% rate, except the money is now headed for her Retirement Account and a CPF LIFE payout. Same cap, same relief, same interest; one outcome is locked to hospital bills and the other becomes lifelong income.
The split matters when MA is the binding constraint. If Priya wanted to fund both, she might put $3,000 into MA to keep insurance premiums covered and $5,000 into SA. That still totals $8,000 of relief, but only the $8,000 in aggregate counts; the cap does not double up by spreading across accounts. The lesson holds at any income: decide what the dollar is for first, because the tax relief is the same either way. The income tax calculator shows the exact saving at your own bracket.
The SA top-up does double duty. It earns 4% today and it builds the pot that becomes your Retirement Account at 55, which CPF later converts into a CPF LIFE monthly payout for life. A dollar in MA can only ever pay a medical bill or an insurance premium; a dollar in SA can become retirement income.
There is also a compounding advantage to topping up early. Money put into the SA at 30 earns 4% (and often the bonus 1%) for 25 years before it even reaches the Retirement Account, then keeps compounding until payouts start. The earlier you start, the smaller the top-up you need to reach the same target. If you want to model this, the compound interest calculator shows how a fixed annual SA top-up grows over time, and the compounding explainer covers why the first years matter most.
MA is not the loser in every scenario. There are clear cases where it should go first.
Self-employed persons must pay compulsory MediSave contributions based on their net trade income. A voluntary cash top-up to your MediSave Account can offset the MediSave payable for the year and still count towards tax relief, subject to the same shared $8,000 cap. If you are self-employed and your MediSave is below the Basic Healthcare Sum, funding MA clears an obligation you owe anyway while earning 4%.
Relief on SA top-ups is only granted up to the current year's FRS of $220,400. If your projected SA balance plus mandatory contributions for the year already reach the FRS, an SA top-up earns no relief. At that point a MediSave top-up, if your MA is still below the $79,000 Basic Healthcare Sum, is the only CPF route left to use the remaining relief.
From 2026 the Government runs the Matched MediSave Scheme, a five-year pilot to 2030 that matches every dollar of voluntary cash top-up to an eligible member's MediSave, up to $1,000 a year. For someone who qualifies, that is an instant 100% return on the first $1,000, which dwarfs the 4% an SA top-up earns. To be eligible you must be a Singapore Citizen aged 55 to 70, hold less than half the Basic Healthcare Sum in MediSave, earn no more than $4,000 a month, own at most one property, and that property's annual value must be no more than $21,000. Eligibility is assessed automatically each year and CPF notifies you at the start of the year.
The catch on the tax side: a top-up that earns the matching grant does not also earn CPF Cash Top-up Relief. For an eligible lower-income member, the $1,000 grant is worth far more than the tax relief would have been, so MA wins that first $1,000 outright. This sits alongside the Matched Retirement Savings Scheme, which does the same for RA top-ups, so check which one you qualify for before deciding where the dollar goes.
If your priority is making sure premiums for MediShield Life and your Integrated Shield Plan are covered for years without touching cash, MA does exactly that. It pays approved premiums directly. For someone close to a large planned medical expense or with thin emergency savings, locking money into MA for healthcare can be the more honest fit than chasing the higher long-run return of SA.
Before locking cash into MA, it helps to know what the account can and cannot do, because that is the real difference from an SA dollar. MediSave is ring-fenced for approved healthcare spending and insurance premiums, with a withdrawal limit on most categories so the balance is not drained in one go.
Premiums for MediShield Life and CareShield Life are deducted from MediSave automatically. Premiums for an Integrated Shield Plan can also be paid from MA, but only up to an age-based Additional Withdrawal Limit; anything above that is paid in cash. The rest of MediSave covers hospital and day-surgery bills, selected outpatient treatments, health screenings, scans and approved chronic-disease care, each with its own cap.
The practical point for the MA-vs-SA call: an MA top-up only ever discharges a healthcare cost. If your insurance premiums already run smoothly off your existing MediSave balance, an extra top-up is money parked for bills you may not face for decades, when the same dollar in SA would be compounding toward a payout you will definitely use.
Both accounts have a hard ceiling, and they behave differently.
The MediSave ceiling is the Basic Healthcare Sum. For 2026 it is $79,000 for members below 65, up from $75,500 in 2025, and it rises most years until you turn 65, at which point your cohort figure is fixed for life. Once your MA hits the BHS, it stops accepting top-ups, and any overflow from mandatory contributions spills into your SA (before 55) or RA. So there is a finite amount of MediSave top-up room, and for higher earners it can already be full from employer contributions alone.
The SA ceiling for relief purposes is the Full Retirement Sum, $220,400 in 2026. You can hold more than the FRS in your SA, but cash top-ups stop earning relief once the FRS is in sight. The FRS itself rises about 3.5% a year for cohorts through 2027, so the relief room generally grows over time. The CPF retirement sum guide lays out the BRS, FRS and ERS figures and how they convert to payouts.
| Ceiling | 2026 amount | What it limits |
|---|---|---|
| Basic Healthcare Sum (BHS) | $79,000 | Max you can hold in MediSave (below 65) |
| Full Retirement Sum (FRS) | $220,400 | Limit for tax relief on SA/RA top-ups |
| Self cash top-up relief | $8,000 | Shared across SA/RA and MA top-ups |
| Family cash top-up relief | $8,000 | Top-ups to loved ones' SA/RA or MA |
| CPF Annual Limit | $37,740 | Total CPF inflows incl. mandatory contributions |
In January 2025 CPF closed the Special Account for members aged 55 and above. This is the single biggest source of confusion when people read older MA-vs-SA articles, so it is worth being precise about who it affects.
If you are under 55, nothing changed. You still have a Special Account, it still earns the SMRA rate, and you can still top it up under RSTU for tax relief up to the FRS. The closure does not touch you yet.
If you are 55 or above, you no longer have an SA. The savings were moved to your Retirement Account up to the FRS, with any excess sent to the Ordinary Account at 2.5%. For this group the question is no longer MA vs SA; it is MA vs RA. Topping up the RA (up to the Enhanced Retirement Sum of $440,800 in 2026) keeps that money at the 4% floor and buys a larger CPF LIFE payout, while OA cash sitting idle earns only 2.5%. The OA vs SA comparison and the Retirement Account explainer cover how the accounts relate after 55.
Both top-ups are done through the CPF website or the CPF Mobile app, and the relief is reflected automatically in your tax assessment the following year. You do not file anything separately with IRAS.
Every CPF top-up is a one-way door. Once the money is in your SA, RA or MA, you cannot pull it back out for a holiday, a renovation, or a market dip. That permanence is the price of the 4% floor and the tax relief.
Before topping up either account, make sure you have an emergency fund of three to six months of expenses in cash, and that you have used cheaper or more flexible wins first. If your marginal tax rate is low, the relief saves you little; the marginal tax rate explainer shows why the same $8,000 top-up is worth far more to a high earner than a fresh graduate. For those weighing CPF against a Supplementary Retirement Scheme contribution, which is also tax-deductible but lets you invest more freely, the SRS vs CPF top-up comparison sets the two side by side.
If you are under 55 and salaried, top up the Special Account first. Both earn 4% and share the same $8,000 tax relief cap, but SA savings later become your Retirement Account and fund a CPF LIFE payout for life, while MediSave is locked to healthcare and caps out at the $79,000 Basic Healthcare Sum. Top up MediSave first only if you are self-employed offsetting MediSave payable, or your SA relief room has already hit the Full Retirement Sum.
Yes. Cash top-ups to your own MediSave Account and your own SA or RA share a single $8,000 relief cap each year. Topping up SA by $8,000 uses the whole cap, so further MediSave top-ups that year earn no extra relief. A separate $8,000 cap applies to top-ups for family members. A top-up made in 2026 is claimed in the 2027 Year of Assessment.
Neither. Both the MediSave and Special Accounts earn the same SMRA floor rate, which is 4.0% per annum for at least the first half of 2026, with the 4% floor extended to 31 December 2026. The Ordinary Account earns 2.5%, which is why people move money into SA or MA rather than leave it in OA.
Yes, if you are under 55. The Special Account closure in January 2025 only applied to members aged 55 and above. If you are below 55 you still have an SA, it still earns the SMRA rate, and you can still top it up under the Retirement Sum Topping-Up scheme for tax relief up to the Full Retirement Sum. Members 55 and above top up their Retirement Account instead.
You can top up your MediSave Account until it reaches the 2026 Basic Healthcare Sum of $79,000. The system blocks any top-up that would push the balance above that ceiling. Only the portion that draws on the shared $8,000 cap earns tax relief, and your total CPF inflows for the year cannot exceed the CPF Annual Limit of $37,740.
Often not. CPF Cash Top-up Relief reduces your chargeable income, so the cash saving equals your top-up multiplied by your marginal tax rate. A high earner can save hundreds or more on an $8,000 top-up, while someone with little or no tax payable saves nothing. If the relief is your only reason, check your marginal rate first; the long-term 4% return may still justify the SA top-up on its own.
No. Cash top-ups to your MediSave, Special or Retirement Account are permanent and cannot be withdrawn on demand. MediSave can only be used for approved medical expenses and premiums, and SA/RA savings are committed to your retirement payouts. Keep a separate emergency fund in cash before topping up either account.
The Matched MediSave Scheme is a Government pilot from 2026 to 2030 that matches every dollar of voluntary cash top-up to an eligible member's MediSave, up to $1,000 a year. To qualify you must be a Singapore Citizen aged 55 to 70, hold less than half the Basic Healthcare Sum in MediSave, earn no more than $4,000 a month, own at most one property with an annual value of $21,000 or less. If you qualify, the matching grant is a 100% return on that first $1,000, which beats topping up SA, but matched top-ups do not also earn tax relief.
MediSave pays for approved healthcare and insurance only. MediShield Life and CareShield Life premiums are deducted automatically, and Integrated Shield Plan premiums can be paid from MediSave up to an age-based Additional Withdrawal Limit, with the rest in cash. It also covers hospitalisation, day surgery, scans, health screenings and approved outpatient or chronic-disease treatment, each with its own withdrawal cap. It cannot be used for everyday spending, housing or general retirement income, which is the core reason an SA top-up is usually the more flexible choice.
