Savings is one of those topics that tends to sit at the bottom of the to-do list for busy business owners. There’s always something more pressing — a client to invoice, a VAT return to file, a cash flow gap to manage. But with interest rates still at levels we haven’t seen for years, and some meaningful tax rule changes landing in 2026/27, it genuinely pays to take stock of where your savings are sitting and whether they’re working as hard as they should be.

According to the ONS, the UK household saving ratio fell to 10.9% in Q1 2025. For many owner-managed business owners, the picture is often more complicated than that headline suggests — you’re saving in multiple places, across personal accounts, business accounts, and sometimes pension wrappers, without a clear strategy linking them together.

In our experience, a bit of structure here can make a meaningful difference. This post sets out how we think about savings for business owners in 2026.

The first and most important principle for any business owner is clarity about what is personal money and what belongs to the business. It sounds obvious, but it’s surprisingly common for the two to blur — especially in the early years of running a company.

Your business current account should not be your emergency fund. Keeping a healthy cash buffer in the business is sensible, but beyond that, surplus cash sitting in a low-interest business current account is quietly losing value in real terms. At the same time, drawing everything out just to park it in a personal easy-access account isn’t necessarily the right answer either — it depends on your tax position, the structure of your business, and what you actually plan to do with the money.

For limited company directors in particular, decisions about where to hold savings — in the company, drawn as salary, taken as dividends, or contributed to a pension — each carry different tax implications. There’s no single right answer, but the worst outcome is making those decisions by default rather than by design.

Before chasing the best savings rate, it’s worth getting clarity on which pot of money you’re actually trying to grow. That context shapes everything else.

The annual ISA allowance remains frozen at £20,000 for 2026/27 — it has been unchanged for several years now, which means inflation has steadily eroded its real value. For anyone with the capacity to save meaningfully, using the full allowance each tax year remains one of the most straightforward tax-efficient moves available to individuals.

There have also been some adjustments to the rules around the taxation of savings interest more broadly this year. The personal savings allowance — the amount of interest you can earn before paying income tax — remains £500 for higher-rate taxpayers and £1,000 for basic-rate taxpayers, but with savings rates still competitive, more people are finding they breach these thresholds than they expected to.

For business owners taking a higher income, the personal savings allowance can disappear entirely at the additional rate threshold. If you’re in that position and holding significant cash savings outside an ISA wrapper, you may be paying more tax on that interest than you need to.

The key takeaway is simple: if you’re not using your ISA allowance each year, you’re leaving a tax-free wrapper on the table. For the right person, a Cash ISA at a competitive rate beats a standard savings account at a higher headline rate once tax is factored in.

For a long time, Cash ISAs were considered barely worth the bother — rates were so low that the tax-free benefit barely mattered. That’s changed. As of June 2026, competitive Cash ISA rates from challenger banks and building societies are sitting at levels that would have seemed remarkable five years ago.

The spread between the best rates and the worst is significant. Leaving money in a legacy instant-access account with a high street bank while better rates are available elsewhere is a common and entirely avoidable oversight. A few hours of comparison shopping — or a conversation with someone who can help — can make a real difference over the course of a year.

That said, the right product depends on how accessible you need the money to be. Fixed-rate ISAs and fixed-term bonds typically offer higher rates in exchange for locking funds away for one, two, or three years. For a business owner, that trade-off matters — you need to be confident the money you lock away won’t be needed if the business hits a difficult patch.

We tend to suggest clients think of their personal savings in layers: an accessible emergency fund (three to six months of personal outgoings), then longer-term savings where the money can work harder. Matching the product to the purpose avoids the situation where you’ve chased a better rate but then need to break the term early.

For limited company directors especially, pension contributions are one of the most tax-efficient ways to save. Employer contributions made directly from a limited company are typically a deductible business expense, reducing the company’s corporation tax bill while simultaneously building a pension pot outside the company.

This makes pensions structurally very different from other savings vehicles. Rather than taking money as a dividend, paying income tax on it, and then saving what’s left, a company pension contribution goes in before tax is paid — at the company level. For higher-rate taxpayers, the effective cost of making a pension contribution is substantially lower than saving the equivalent amount from post-tax income.

The annual allowance for pension contributions currently stands at £60,000 per year (or 100% of earnings if lower), though the rules around carry-forward and high earners can get complicated. If you’ve been deferring pension contributions while building your business — which is understandable in the early years — it’s worth understanding whether you can make use of carry-forward to catch up.

Pensions aren’t the right vehicle for every pound of savings. The money is locked away until at least age 57 (rising to 58 by 2028), so they sit alongside rather than instead of more accessible savings. But for business owners thinking about long-term wealth building, ignoring pensions while chasing Cash ISA rates is missing the bigger opportunity.
