How a good year can cost you thousands in tax

Is the cash actually yours to take?

There’s a question that catches more e-commerce founders than it should: is the cash you’re looking at genuinely available to extract? In a fast-growing online business, three things routinely come apart: the profit on your accounts, the cash in your bank, and the amount you can lawfully pay yourself.

This matters because money drawn without the reserves to back it isn’t tax-free cash in your hands at all — it doesn’t become a dividend, it becomes a loan you owe back to the company, and an overdrawn loan account left unpaid carries its own tax charge. Get this wrong and an efficient extraction plan can still land you with an unexpected tax charge or an unlawful dividend.

^{Before you draw
‍}“Profit, cash and what you can lawfully draw are three different numbers.”

Wealth extraction is not a single decision but a sequence that should change as profits grow. The most efficient mix at £50,000 of surplus is rarely the right mix at £150,000. A useful way to think about it is in three broad stages, each with its own tools, its own statutory limits and its own trade-offs. The stages below are KKG’s own framing for that progression, not statutory terms:

Stage 1: Getting the salary and dividend mix right

For most e-commerce companies we work with, the starting point is straightforward: pay the director a salary of £12,570 (the personal allowance) and take the rest of your income as dividends. That salary is high enough to count as a qualifying year for the State Pension, low enough to keep employer National Insurance manageable, and it's tax deductible so it reduces your corporation tax bill. If your company can claim the Employment Allowance, this is almost always the right number.

The single-director exception

The main exception is a company with a single director and no other employees: it can’t claim the allowance, so there’s a modest employer NIC cost on the salary above the £5,000 secondary threshold — but once you weigh that against the corporation tax relief, £12,570 still usually comes out ahead. It’s a calculation worth running rather than assuming.

How far to push dividends

From there, draw dividends up to the top of the basic-rate band (broadly £50,270 of total income) where the profit and your personal cash needs allow. If your spouse or family are involved in the business, there may be scope to extract more across the household’s allowances rather than stacking it all onto your income — but that’s a planning layer in its own right, and we cover it in Stage 2.

Why the mix should move with your cash

One e-commerce-specific point: don’t treat this mix as fixed for the year. If your profit is seasonal or your cash is tied up in stock, the dividends you can actually take will move with the business. It’s often better to leave cash in the company to fund your Q4 inventory than to draw dividends you’ll only end up lending back. We’d typically set the salary in April and review the dividend position once your year-end profit is clearer. Plan for the tax's own timing too; in your first strong year, payments on account can land roughly one and a half times the bill in a single January.

Stage 2: Using the whole houselhold's allowance

Once your own salary and dividends are working efficiently, the next lever is to use other people's allowances. If your spouse or family genuinely contribute to the business, the household has more allowances and tax bands than you can use alone, and the goal becomes getting money out across all of them rather than stacking it onto your income.

Wages, dividends and a spouse’s pension

Our default recommendations here are threefold. First, employing a spouse or older children who do real work in the business — they can be paid a commercial wage for genuine duties, which is deductible for the company and uses their personal allowance. Second, the dividend split: where a spouse genuinely co-owns the company, dividends can run across both of your allowances and basic-rate bands. Third, an employer pension contribution for a spouse who works in the business, on the same efficient basis as your own.

The word that matters: genuine

The work needs to be genuine. Pay for real work at a commercial rate, an inflated wage for token duties fails the “wholly and exclusively” test and isn’t deductible. A dividend split only works if your spouse holds real ordinary shares, gifted outright with full voting and capital rights; an income-only arrangement invites an HMRC challenge under the settlements rules. And a pension contribution must be justifiable against their actual role in the business.

What the household layer is worth

For an e-commerce founder this is often more practical than it first sounds. A partner handling customer service, fulfilment, bookkeeping or marketing is doing genuine, evidenced work. Done properly, this layer meaningfully increases what the household extracts each year. Done as a paper exercise, it’s a risk that outweighs the saving — so document the roles, pay commercial rates, and structure any share gift correctly from the outset.

Stage 3: When pensions beat dividends

Once your own and the household's bands are used up, the maths turns against further dividends. They’re taxed at 33.75% in the higher-rate band and 39.35% above it. And worst of all between £100,000 and £125,140, where your personal allowance tapers away and the effective marginal rate reaches roughly 60%. If you have children, two more thresholds bite here: child benefit tapers away above £60,000, and free childcare disappears at £100,000 — both recoverable by paying into a pension

‍

The employer pension contribution

For surplus cash at this point, our default recommendation is an employer pension contribution rather than further dividends. Paid by the company into the director’s pension, it’s normally deductible for corporation tax (subject to the “wholly and exclusively” test) and isn’t taxed as your personal income going in — so profit moves across largely intact instead of being taxed twice.

The catch: no access until 55 (rising to 57)

The catch is that this isn’t extraction in the everyday sense: pension funds generally can’t be accessed until age 55, rising to 57 from 6 April 2028. So, the first question is whether you’ll need the money before then. E-commerce owners should be especially careful here, cash that looks surplus in March is often exactly what you want for Q4 stock. The pension route suits genuine long-term surplus, not money that’s merely idle today.

Keeping within the annual allowance

There’s also a ceiling on how much you can pay in: the annual allowance caps the contributions that attract tax relief each year, and that allowance is reduced further for high earners under the tapering rules. Carry-forward of unused allowance from the previous three years can stretch that ceiling in a bumper year. For a genuinely profitable business, the surplus in a strong year can exceed what a pension will absorb — another reason to plan the timing rather than divert cash in a single lump.

Other levers worth knowing

The three stages above are the workhorses, but they aren’t the whole toolkit. A handful of smaller levers sit alongside them, and for a profitable e-commerce company they’re worth a deliberate look.

Charging the company rent

If you personally own premises the business trades from, or you genuinely work from home, the company can pay you a commercial rent for that space. Rent is deductible for the company and, unlike salary, carries no National Insurance. But charging rent on a property can affect the capital gains reliefs available when you eventually sell it, so it’s a trade-off to weigh rather than a free win. In the same vein, if you’ve lent your own money into the company, which is common in the early, cash-hungry years of an online business; the company can pay you interest on that loan, again outside the dividend regime.

The small tax-free allowances

Then there are the small, often-overlooked allowances: the company can reimburse approved mileage and a flat home-working allowance, both tax-free, and modest tax-free perks such as trivial benefits and an annual staff function. None of these is transformational on its own, but they’re the natural extension of the “use every allowance” principle behind Stage 2. A fully electric company car is a larger version of the same idea: the benefit-in-kind charge is still comparatively low, the company gets relief on the cost, and it funds a personal-use asset efficiently; though the benefit rates are rising, so the maths is worth checking before you commit.

The big one: your eventual exit

One final point that this article deliberately sets to one side: everything above is about extracting cash while you trade. The single largest tax-efficient extraction in most founders’ lives is the eventual exit: selling the business, or winding it down and drawing the retained profits as capital rather than income. That sits in an entirely different part of the tax code, with its own reliefs and its own long lead times, and it’s a planning exercise in its own right. It’s worth knowing now, though, that the way you structure shareholdings today (the very same spousal split that powers Stage 2) can shape what that exit looks like years before it happens.

What to actually do

1. Check the cash is yours to take first Before extracting, confirm the company has the distributable reserves to cover a dividend (reserves, not bank balance) and keep an eye on your director’s loan account so you don’t drift overdrawn. Profit, cash and what you can lawfully draw are three different numbers.
2. Plan draws across  tax years, not in lump sums Concentrating a large sum into a single tax year can push income needlessly into higher bands; spreading the same amount across years draws on each year's allowances and basic-rate band. Set a regular draw based on your expected year-end profit, and revisit it as the picture firms up.
3. Work the three stages in order Get the salary and dividend mix right first; use the household's allowances once your own are full; then divert genuine long-term surplus into an employer pension.
4. Time it around your trading cycle If your profit is seasonal or your cash is tied up in stock, don’t extract cash you’ll need for Q4 inventory; leave it in the company rather than drawing dividends you’ll only lend back.
5. Keep the family planning genuine. Spousal dividends, family wages and a spouse’s pension all work, but only with real shareholdings, real work at commercial rates, and proper documentation.
6. Talk to us before year-end, not after Most of this only works if it’s set up while the year is still running. Once the year has closed, your options narrow.
