The Personal Allowance is the amount of income you can receive before paying income tax, and it is currently £12,570. For many people that sounds simple, but if you're a limited company director earning near or above £100,000, that headline number can mislead you because it doesn't stay intact.
If your company profits are rising, you've probably felt this already. You pay yourself a salary, take dividends, maybe add some interest or other income, then wonder why crossing a certain point seems to hammer your take-home pay harder than expected. That's because the personal allowance isn't just a tax-free perk. For directors, it's a planning lever. Used well, it helps you keep more of what you earn. Ignored, it drags you into one of the nastiest bands in the UK tax system.
Most basic guides stop at the definition. That's not enough. If you run a limited company, the key question isn't only what is a personal allowance. The more significant question is whether your pay strategy is preserving it, wasting it, or accidentally giving it back.
Your Guide to the Personal Allowance
You take a dividend that pushes your total income just over £100,000, then wonder why the extra money barely feels worth it. That is the point where the personal allowance stops being a basic tax-free threshold and starts becoming a director planning problem.
The personal allowance is the amount of income you can receive before income tax applies. It is currently £12,570. For a limited company director, the headline figure matters less than what happens when your total income starts to chip away at it.
Why directors need to care
A director has more control than an employee on PAYE. You can set salary, choose when to declare dividends, and decide whether to extract profits this tax year or leave them in the company. Those choices shape whether you keep your allowance or lose part of it.
That is the part many directors miss.
The personal allowance is not just a background tax rule. It is one of the pressure points in your remuneration plan. If you ignore it, you can drift into the £100,000 taper and create a punishing marginal tax position without realising it.
The version that matters for directors
For directors, the useful question is not whether the personal allowance exists. It is whether your income plan protects it.
- Up to £12,570 can be covered by your personal allowance: If your total taxable income stays within that level, no income tax is due on that slice.
- Income above that level becomes taxable: The tax you pay then depends on the type of income and the band it falls into.
- Once income moves above £100,000, the allowance starts shrinking: That is where planning gets serious, because each extra pound can cost far more than many directors expect.
If you are checking different pay options, run the numbers before declaring anything. A quick salary after tax calculation for directors will show whether a small increase in extraction improves your net position.
Practical rule: Treat the personal allowance as part of your profit extraction strategy.
Directors who stay well below £100,000 can often use the allowance without much friction. Directors hovering around that level need tighter control. A bonus, a larger dividend, rental income, or bank interest can be enough to start eroding it.
That is why casual year-end dividend decisions are expensive. If your income is anywhere near six figures, review the full picture before you vote another payment.
How the Personal Allowance Works in Practice
You pay yourself a modest salary, vote a dividend near year end, then realise other income has soaked up more of your personal allowance than expected. That mistake is common among limited company directors, and it usually shows up too late to fix cleanly.
Your personal allowance is used against income in a set order. For directors, that matters because pay rarely comes from one stream. You may have salary from your company, dividends, bank interest, rental income, or benefits. The mix changes the outcome.
Start with the income order
In broad terms, the personal allowance usually goes against non-savings income first, such as salary, before savings or dividends. That often works well for directors, but not always. If you have several income sources, the allowance can land in a less efficient place than you expected.
A common oversight for directors is treating all income types equally for tax purposes. They are not taxed the same way, and they do not use the allowance in the same way either.
- Salary usually uses the allowance first. That can be efficient if your salary level is deliberate.
- Dividends do not automatically get first use of it. A dividend-heavy extraction plan still needs checking against the rest of your income.
- Savings interest and other taxable income can distort the picture. Small amounts can still affect how much allowance is left for the income you planned around.
What this means for your remuneration
A low salary and larger dividends can work well. It can also backfire if you ignore the full income picture.
A significant risk is not the allowance itself. The greater danger is drifting toward £100,000 adjusted net income without noticing, then adding one more dividend or bonus that pushes you into the taper. At that point, a sloppy pay mix stops being a small inefficiency and starts becoming expensive.
If you are weighing up salary and dividends, run the numbers before approving anything. A salary after tax calculator for director pay planning will help you spot when an extra extraction improves cash flow and when it instead creates more tax.
Treat your personal allowance as part of your annual extraction plan, not as a background tax rule.
A practical director checklist
Ask yourself:
- Which income source is using my personal allowance first?
- Am I wasting allowance because my salary, dividends, and other income are poorly timed?
- Will this extra payment push me closer to the £100,000 danger zone?
Directors who ask those questions early usually keep more of what they earn. Directors who leave it until the year-end accounts often find they have created a tax problem with no clean way back.
The Tapered Allowance for Higher Earners
You approve an extra dividend because the company had a good year. Then your tax position gets worse faster than expected. For a limited company director, that usually starts at £100,000 adjusted net income, where the personal allowance begins to taper away.
The rule is simple. Once your adjusted net income goes above £100,000, your personal allowance falls by £1 for every £2 of extra income. By £125,140, it is gone.
The trigger point directors must watch
For directors, £100,000 is not just another threshold. It is the point where a routine extraction decision can become expensive.
One more dividend. One bonus through payroll. One extra source of taxable income. Any of those can start stripping away the allowance that was sheltering part of your income from tax.
That is why this catches directors who otherwise run their companies well. They may be disciplined on corporation tax and dividend planning, but still miss the personal tax cost of crossing the taper line. If you want a quick sense of the impact, this take-home pay on a £100k salary guide shows why this threshold deserves proper attention.
A quick visual often helps:
The maths is simple. The planning is not.
Use these three checkpoints:
- At £100,000: your full personal allowance is still available.
- Above £100,000: every extra £2 reduces your allowance by £1.
- At £125,140: your personal allowance has been fully removed.
The calculation is easy. The mistake is treating it as background admin rather than a pay-planning issue.
Directors rarely receive income from one clean source. Salary, dividends, benefits, rental income, savings interest, and other taxable amounts can all affect the position. That is why a director can feel comfortably below the line while the full tax picture says otherwise.
Why adjusted net income matters
The taper is based on adjusted net income, not the salary figure you happen to remember from payroll.
This is the starting point for strategic planning. If you only track PAYE salary and ignore dividends or other taxable income, you can cross into the taper without noticing until it is too late to fix cleanly.
Director warning: The costly mistake is assuming your personal allowance will still be there at year end just because your salary looked sensible.
For a limited company director, the right question is not “What can I take out?” It is “What extraction mix keeps me clear of the taper, or at least makes the cost worth paying?” That is the point of managing this threshold properly.
The 60% Marginal Tax Rate Trap Explained
This is the part that annoys people, and rightly so.
The band created by the taper produces a very high marginal tax effect for income between £100,000 and £125,140, as highlighted in FreeAgent's explanation of the personal allowance income trap. People often call this the 60% tax trap.
Why the rate feels so brutal
It isn't a separate official HMRC tax band. It's an effect.
You earn extra income in that range and pay higher-rate tax on it. At the same time, you lose part of your personal allowance. Losing that allowance means more of your existing income becomes taxable as well. So the extra income hurts twice.
That's why directors are often baffled by the jump in tax. They look at one extra slice of income and expect one tax charge. What they get is tax on the new income plus tax triggered by the shrinking allowance.
Worked example of the 60% tax trap
A simple example makes it clear. Assume income moves from £100,000 to £110,000.
| Item | Calculation | Amount |
|---|---|---|
| Extra income received | Income above £100,000 | £10,000 |
| Higher-rate tax on extra income | 40% of £10,000 | £4,000 |
| Personal Allowance lost | £1 lost for every £2 above £100,000 | £5,000 |
| Extra income now exposed to tax because allowance is lost | Taxed at 40% | £2,000 |
| Total extra tax triggered | £4,000 + £2,000 | £6,000 |
That means £10,000 of extra income can trigger £6,000 of income tax in this band. That's why people refer to a 60% marginal rate on that slice.
Why this matters more for directors than employees
Employees often fall into this band because of a pay rise or bonus. Directors can fall into it through choices they control, which is why poor planning is even harder to excuse.
Common triggers include:
- Late dividend decisions: You leave extraction until year end, then overshoot.
- Bonus thinking: You pay yourself more from the company without checking the adjusted net income effect.
- Ignoring the full picture: Salary looks manageable, but dividends and other income push you into the trap.
If you're trying to assess whether six-figure income is still working for you, this guide on take-home pay on a £100k salary is a useful benchmark.
A director can increase gross income and still feel poorer than expected. This band is usually the reason.
The right conclusion
Don't obsess over the label. Whether you call it a taper, an income trap or a 60% marginal rate, the conclusion is the same.
If you're in this zone, casual pay planning is expensive. The wrong dividend, the wrong bonus timing, or the wrong pension decision can turn profitable trading into avoidable personal tax drag.
Strategic Planning for Company Directors
You finish a profitable year, declare one more dividend, and then realise that extra income did more than add tax at the top rate. It also stripped away part of your personal allowance. For a limited company director, that mistake is expensive and avoidable.
The directors who handle this well do not treat remuneration as a year-end clean-up job. They set it up deliberately across salary, dividends, pension funding, and timing. The target is simple. Keep control of adjusted net income so you do not drift into the taper without noticing.
Build your remuneration plan before year end
If your income is anywhere near six figures, guessing is careless.
Start with a full income forecast for the tax year. Include salary, dividends, benefits, savings income, rental income, and anything else that feeds into your personal position. Many directors look only at PAYE and then get caught by dividends declared late in the year.
Your review should answer three practical questions:
- How much income do you need personally? If you do not need to extract it now, leaving profit in the company can be cheaper than forcing yourself into the taper zone.
- Is your salary doing a useful job? A salary should support your wider tax plan, not undermine it.
- Are dividends being declared with a tax number in mind? If not, you are making distribution decisions blind.
The point is not to chase the highest gross income. The point is to keep more of what the company earns after tax.
Use pensions as a tax control tool
For directors in or near the taper band, pension contributions are often the cleanest fix.
They can reduce adjusted net income and help preserve your personal allowance. That makes them more than a retirement decision. They are a current-year planning tool. Used properly, they can stop a small overshoot from turning into a costly personal tax problem.
If you are considering this route, review how salary sacrifice can cut tax for higher earners and compare it with employer pension contributions from your company.
Before you extract extra income, check whether paying more into a pension gives you a better net result.
Control timing with intent
Bunching income is one of the most common director mistakes.
A large dividend in March, a bonus after profits come in, or a delayed decision once the accounts are clearer can push one tax year into the taper even when your earnings are steady over time. That is bad planning, not bad luck.
Check the timing of:
- Dividends. Split them across tax years if the commercial position allows.
- Bonuses. A bonus paid in the wrong year can create a personal tax spike with no real financial upside.
- Other household income. If shares are already structured appropriately, review whether income is concentrated too heavily on one person.
Timing matters because the taper is based on the tax year in front of you, not the story you tell yourself about long-term averages.
Do not ignore smaller reliefs
Gift Aid can help reduce adjusted net income. That will not rescue poor remuneration planning on its own, but it can improve the result if you already intend to donate.
Some directors also consider EIS or SEIS. Treat those as investment decisions first. Tax relief does not turn a weak investment into a good one.
What good planning looks like
A director with a strong plan usually does the following:
| Planning area | What good looks like |
|---|---|
| Salary | Set at a deliberate level that supports the wider extraction plan |
| Dividends | Declared to fit your tax position, not just available reserves |
| Pension | Used to manage adjusted net income where needed |
| Donations | Included in the numbers if Gift Aid is relevant |
| Household planning | Reviewed so income is not concentrated inefficiently |
Here is the practical rule. If your income is near £100,000, every extra pound needs a reason. Casual extraction in this range is how directors fall into the 60% trap and wonder why strong profits produced a weak personal result.
Managing Your Allowance and Seeking Advice
A personal allowance looks simple on paper. For a director, it isn't simple in practice.
The danger is rarely ignorance of the headline amount. It is widely understood that a tax-free threshold exists. Instead, the challenge often stems from poor execution. They misjudge adjusted net income, take dividends too late, bunch income into one year, or fail to use pensions and other reliefs when the taper starts biting.
Common mistakes that create unnecessary tax
Some errors come up again and again:
- Relying on rough estimates: Directors often guess their year-end income and get it wrong.
- Looking only at salary: That misses the wider income picture.
- Making decisions too late: By the time the accounts are done and dividends are declared, the planning window may have narrowed.
If your income is anywhere near the taper zone, tax planning done after the fact is usually damage control, not strategy.
The right next move
If your income is comfortably below the taper threshold, the main goal is to use the allowance sensibly and keep your remuneration structure tidy.
If you're approaching or sitting within that band, the personal allowance becomes a strategic issue. At that point, reviewing salary, dividends, pension contributions, donation planning and timing isn't optional if you want to avoid needless tax leakage.
The directors who handle this well don't wait for a surprise tax bill. They review their position before year end, model the effect of extra income, and act early.
