Have you ever wondered how to make your savings work harder without losing a chunk to taxes? With whispers of potential cuts to the cash ISA allowance swirling, many savers are on edge, worried about how to protect their hard-earned money. The good news? There’s a clever way to keep earning solid, tax-free returns without relying solely on a cash ISA. By diving into the world of money market funds within a stocks and shares ISA, you can potentially pocket over 4%—sometimes even 5%—without the taxman taking a bite.
Why Stocks and Shares ISAs Are Your Secret Weapon
The financial world is buzzing with speculation that the cash ISA allowance—currently a generous £20,000 per tax year—might face a drastic cut. Some experts suggest it could drop to as low as £4,000 or £5,000. For higher earners, this could mean a hefty 45% tax on interest earned above the new limit. But here’s where things get interesting: a stocks and shares ISA offers a workaround that’s both low-risk and tax-efficient. By investing in money market funds, you can keep your returns shielded from HMRC while enjoying yields that rival or beat traditional savings accounts.
I’ve always found it frustrating when policy changes threaten to chip away at our financial freedom. Yet, this potential ISA limit cut feels like an opportunity to explore smarter strategies. Let’s break down how you can use a stocks and shares ISA to stay ahead of the game.
What Are Money Market Funds, Anyway?
Think of money market funds as the cool, low-risk cousin of traditional investments. These funds pool your money into short-term, high-quality debt instruments—like government bonds, bank certificates, or corporate debt with strong credit ratings. Their goal? To deliver steady, predictable returns that track UK interest rates, much like a savings account, but with the added perk of being held in a tax-free wrapper like a stocks and shares ISA.
Money market funds offer a stable, cash-like return without the volatility of stocks, making them a great fit for cautious savers.

Unlike riskier stock market investments, these funds prioritize safety. They’re designed to keep your capital secure while generating a modest income. With interest rates hovering above 4%, many funds are currently offering yields that make them a compelling alternative to cash ISAs or regular savings accounts.
How Much Can You Earn?
The big draw of money market funds is their yield—the income they generate. Right now, some of the top-performing funds are delivering between 4% and 5.3% annually. For example, certain funds track the Bank of England’s Sterling Overnight Index Average (SONIA), which sits around 4.25%. While these yields aren’t guaranteed and can fluctuate, they’re a solid benchmark for what you might expect.
- Typical yields: Many funds offer 4% to 5.3% based on the past 12 months.
- Variability: Yields can dip if interest rates fall, so keep an eye on economic trends.
- Tax-free perk: When held in a stocks and shares ISA, every penny of that yield is yours to keep.
Here’s a quick reality check: if you invested £20,000 in a fund yielding 4.8%, you’d earn around £960 a year, tax-free. Compare that to a savings account where you might lose nearly half to taxes if you’re a higher-rate taxpayer. It’s a no-brainer for anyone looking to maximize their returns without taking on much risk.
Are Money Market Funds Risk-Free?
Let’s get one thing straight: no investment is entirely risk-free, and money market funds are no exception. While they’re considered low-risk, there are a couple of things to watch out for. For starters, yields can vary, and in rare cases, returns might even turn negative if interest rates plummet or fund charges eat into profits.
Back during the 2008 financial crisis, some funds took a hit when uncertainty rocked the banking sector. Thankfully, regulations have tightened since then, making such events less likely. Still, it’s worth noting that money market funds don’t come with the £85,000 Financial Services Compensation Scheme protection you’d get with a savings account or cash ISA.
While money market funds are low-risk, they’re not bulletproof. Always understand the trade-offs before investing.

That said, many financial institutions stand behind their funds, often covering small losses to keep investors happy. In my view, the risk is minimal for most savers, especially if you’re using these funds as a short-term, cash-like option within your ISA.
How to Use Your Full ISA Allowance
One of the best parts about a stocks and shares ISA is its flexibility. You can pour your entire £20,000 annual allowance into money market funds if you want. Or, if the cash ISA limit drops to, say, £5,000, you could split your strategy: keep £5,000 in a cash ISA and invest the remaining £15,000 in money market funds via a stocks and shares ISA.
| Option | Amount | Tax-Free? |
| Cash ISA | Up to £5,000 (if reduced) | Yes |
| Stocks and Shares ISA (Money Market Funds) | Up to £20,000 | Yes |
| Regular Savings Account | Unlimited | No |
This approach lets you maximize your tax-free allowance while keeping things low-risk. But if your goal is long-term wealth growth, you might want to mix in some equities or other assets. Money market funds are great for stability, but stocks could offer higher returns over time—though with more volatility.
Another Cash Option: Parking Funds in Your ISA
Not ready to commit to a money market fund? Most investment platforms let you “park” your money in cash within a stocks and shares ISA while you decide what to do next. Some platforms even pay decent interest on these cash balances—sometimes as high as 4.3% or more, depending on the provider.
- Check the interest rate: Some platforms offer as little as 1%, while others are far more competitive.
- Compare platforms: Look for ones with low fees and high cash yields.
- Plan your next move: Use the time to research funds or stocks for long-term growth.
This strategy is perfect if you’re new to investing or just want a safe place to stash your cash while you figure things out. Personally, I think it’s a smart way to keep your money working without jumping into riskier assets right away.
Why Now Is the Time to Act
With talk of a cash ISA limit cut looming, now’s the moment to explore your options. Money market funds within a stocks and shares ISA offer a rare blend of tax efficiency, decent returns, and low risk. They’re not perfect—yields can dip, and there’s no government-backed safety net—but for many savers, they’re a game-changer.
Perhaps the most exciting part is the flexibility. You can tailor your ISA to fit your comfort level, whether that’s sticking with cash-like funds or dipping a toe into the stock market. Whatever you choose, the key is to stay proactive. Don’t let potential policy changes catch you off guard—start planning today to keep your savings tax-free and thriving.
So, what’s your next step? Are you ready to explore money market funds, or will you park your cash while you weigh your options? One thing’s for sure: with a stocks and shares ISA, you’ve got the tools to make your money work smarter, not harder. Let’s beat the taxman together.
