The UK tax year starts on 6 April. It ends on 5 April the following year, so the 2026/27 tax year begins on 6 April 2026.
If you're a limited company director, that date matters far more than it first appears. One week you're thinking about company profit, payroll, and whether to vote a dividend. The next, you're trying to remember which decisions belong to you personally and which belong to the company. That confusion is common, and it usually shows up right when time is shortest.
Many individuals search for the date new tax year starts because they want a simple answer. Directors need something more useful. You need to know why that date shapes salary planning, dividend timing, pension contributions, and the cut-off point for decisions that can change your personal tax position.
Think of 6 April as the opening day of a new planning season. 5 April is the closing bell on the old one. If you only treat those dates as admin markers, you miss the point. For a director, they mark the handover between one set of opportunities and the next.
The Most Important Date in a Director's Diary
If your year-end routine feels messy, you're not alone. A lot of directors reach late March or early April and suddenly realise they still need to review dividends, pension contributions, drawings, and personal income. The pressure comes from trying to tidy up a whole year in a small window.
The core rule is simple. The UK tax year starts on 6 April and ends on 5 April the following year. The pattern is fixed, and the 2026/27 tax year begins on 6 April 2026, as explained in this guide to when the UK tax year starts and ends.
That sounds like a calendar fact. For a director, it's really a planning trigger.
Why directors need to care
You live with two financial realities at once. You have your company, which earns profits and pays money out. Then you have your personal tax position, which decides how salary, dividends, pension funding, and other income are assessed.
When those two aren't lined up in your head, poor timing creeps in. You can make a perfectly sensible company decision that lands awkwardly on your personal side because it happened before or after 5 April.
Practical rule: The date new tax year starts isn't just about compliance. It tells you when your personal tax clock resets.
The shift from deadline to opportunity
Many directors treat early April like a filing problem. That's too narrow. It's a decision point.
Use 5 April to ask what still needs to happen in the current tax year. Use 6 April to ask how you want the next year to look. That change in mindset matters because tax planning works best before money is paid, not after.
A good way to think about it is like closing one notebook and opening another. Once the page turns, some choices belong to the old year and some only work in the new one. Knowing which is which helps you stop reacting and start directing the flow of income more deliberately.
Why the UK Tax Year Starts on 6 April
The 6 April start date feels odd because it doesn't match the calendar year. That isn't a mistake. It's a long-standing feature of the UK system, and it's why tax planning often feels slightly out of step with the rest of business life.
Historically, the unusual date comes from changes to the calendar that left the tax year on its own track. You don't need the full history lesson to use the rule well, but it helps to know this isn't some temporary quirk. It's firmly established in how UK personal tax works.
Why the odd date still matters now
The practical point is more important than the history. Your personal tax affairs are measured against an April to April cycle, not a January to December one. That applies across the areas directors usually care about most, including income, dividends, and pension planning.
If you're trying to build a clean mental model, stop thinking in calendar years when you're making personal tax decisions. Start thinking in tax years.
A useful primer on the broader framework sits in this tax year overview.
Where people get tripped up
Most confusion comes from habit. Your diary, management accounts, and commercial plans often run by month, quarter, or calendar year. Tax doesn't.
That creates awkward moments such as:
- A dividend feels like a spring decision when, for tax purposes, the exact day can put it in one tax year or the next
- A pension contribution feels annual but the relevant cut-off for personal tax planning is still tied to the tax year
- A personal income review gets delayed because January feels like a natural reset, even though the tax system hasn't reset then
The tax year is its own lane. If you plan by the calendar alone, you'll often act too early, too late, or in the wrong sequence.
The real lesson for directors
You don't need to like the date. You just need to respect it.
Once you accept that the tax system runs on an April cycle, the date new tax year starts becomes easier to work with. Instead of asking, "Why is it like this?" the better question is, "What decisions should I make before 5 April, and what decisions are better held back until after 6 April?"
That shift is where useful planning starts.
Personal Tax Year vs Your Company's Financial Year
This is the point that confuses directors most. Your personal tax year is not the same thing as your company's financial year.
They may overlap. They may sit close together. They may be nowhere near each other. But they are not the same clock.
Two clocks running at once
Think of it as wearing two watches.
One watch is set by HMRC for you as an individual. That is the personal tax year. It always runs from 6 April to 5 April.
The other watch is set by your company accounts. That financial year can end on a different date depending on how the company was set up and what accounting period it uses. If you need a separate guide to that side of the timing, this explainer on the tax year end for planning purposes helps.
Why this matters in real life
Company profits sit inside the company until you extract them. The moment you pay yourself, timing starts to matter personally.
That means a director has to ask two different questions:
| Question | Whose clock matters |
|---|---|
| When does the company recognise income and prepare accounts? | The company's financial year |
| When does the payment count for me personally? | Your personal tax year |
This is why two payments from the same pot of company profit can land differently for you.
A simple timing example
Suppose your company has enough retained profit to support a dividend. If that dividend is declared and paid just before 5 April, it falls into one personal tax year. If the same amount is declared and paid just after 6 April, it falls into the next one.
The company may still be using the same bank account, the same profit pool, and the same overall commercial plan. But your personal tax position has shifted because your own clock has moved on.
That is why directors often feel caught out. They are looking at the company watch when they should be checking the personal one.
Director's lens: A company decision doesn't become a personal tax event when you think about it. It becomes one when the payment is actually made and falls into your tax year.
Common signs you're mixing the two up
- You look only at year-end accounts and assume that tells you everything about your personal tax position
- You vote dividends late without checking whether crossing 5 April changes your outcome
- You plan pension funding from company cash flow alone without asking which personal tax year you want the contribution linked to
- You say "this tax year" when you really mean the company's accounting year
That last one sounds minor, but it's where a lot of mistakes start. Precise language leads to better decisions.
Key Planning Windows for Company Directors
For directors, the key date is not just when the new tax year starts. It's the narrow band around 5 April and 6 April where decisions stop belonging to one year and start belonging to another.
Treat that period like the handover between two shifts. One team is finishing. Another is taking over. If instructions are unclear, things get missed.
Before 5 April
This is your last chance to make decisions count in the current personal tax year. By this stage, you're usually not inventing a brand-new strategy. You're checking whether the existing one has been used properly.
Focus on the decisions that can still be controlled before the cut-off:
- Salary review: Check whether your salary level still fits the wider remuneration plan and whether payroll timing matches what you intended personally.
- Dividend timing: Review whether a dividend should be taken before the tax year closes, or deliberately left until after the new one begins.
- Pension funding: Consider whether a personal or company pension contribution belongs in the current year rather than the next.
- Investment wrappers: If you use an ISA or other personal planning tools, decide whether you want the current year's opportunity used before it disappears.
- Capital transactions: If you're already planning to sell or transfer assets, timing can change which tax year the gain sits in.
The cut-off on 5 April
5 April is the line in the sand for personal tax planning. Once that date passes, the old year's unused opportunities generally stop being current-year opportunities.
Directors often get frustrated because they may have had the right idea, but the action happened too late. In tax planning, timing is part of the strategy, not a small detail at the end.
If a decision depends on the tax year, "almost done" isn't done. The tax year only recognises what actually happened by the deadline.
After 6 April
Once the new tax year opens, the pressure changes. You're no longer trying to rescue the old year. You're setting the tone for the new one.
A useful first review covers these areas:
Map expected income
Estimate what you'll likely take as salary, dividends, and any other personal income over the year.Check company cash flow
Your personal plan only works if the company can support it without creating strain elsewhere.Set pension intentions early
Early planning is usually cleaner than trying to fix everything near the deadline.Watch interaction with company obligations
Your company has its own tax and filing rhythm. Even though that sits on a different timetable, it still affects the cash available for personal planning.
Why Corporation Tax still matters here
Corporation Tax doesn't run on your personal tax year. But it still affects director planning because company cash is finite. A company may look profitable on paper while cash is already spoken for by tax, VAT, payroll, or upcoming liabilities.
So even though the personal cut-off is 5 April, good planning always asks one extra question. Can the company fund this sensibly, or am I solving one tax issue by creating a cash issue elsewhere?
Optimising Your Finances Before 5 April A Practical Example
Directors usually understand the theory once it's explained. The harder part is seeing how several moving parts fit together in one decision. A practical example helps.
Let's use Alex, a limited company director. Alex has had a good year, has company profits available, and wants to avoid the usual late-March scramble. The aim isn't to invent clever tricks. It's to make sure the right actions happen in the right tax year.
Step one starts with the personal picture
Alex's first mistake in earlier years was looking only at company profit. That gave half the story.
This time, Alex begins by listing expected personal income for the current tax year, including salary already taken, dividends already voted, and any other income outside the company. That creates a working map. Without it, any extra dividend or pension contribution is just guesswork.
Step two checks whether extraction still makes sense
Now Alex asks a more strategic question. Is it better to take more money before 5 April, or leave it until after 6 April when a new personal tax year begins?
There isn't one universal answer. If Alex has room in the current year for extra extraction without creating a poor tax result, taking funds before 5 April may be sensible. If the current year already looks crowded, delaying until the new year may be cleaner.
Many directors slip at this point. They focus on whether they can take a dividend, when the better question is whether they should take it now.
Planning insight: Don't treat dividends like taps you turn on whenever cash is available. Treat them like timed releases that need to land in the right tax year.
Step three uses pensions as a pressure valve
Suppose Alex realises personal income is already high enough that taking more cash now feels inefficient. A company pension contribution may become part of the discussion.
That doesn't mean pensions are always the answer. It means they can change the shape of extraction when taking more cash personally before 5 April no longer looks attractive. For many directors, the company and personal plan can then begin to work together rather than fighting each other.
If you want to understand the framework in more detail, this guide to pension contributions and annual allowance planning is worth reviewing.
A short explainer can also help if you prefer to hear the logic worked through:
Step four avoids the all-or-nothing mindset
Alex doesn't need one giant move. Often the best result comes from a combination of smaller decisions:
- A final dividend review if the current tax year still has space for further extraction
- A pension contribution decision if moving cash out personally now looks less attractive
- An ISA funding plan so personal savings strategy is not left until after the deadline
- A hold decision where doing nothing before 5 April is better than rushing into the wrong year
What this example really shows
The value isn't in memorising Alex's situation. It's in the sequence.
Start with the personal tax year. Overlay company cash and profit. Check timing. Then decide whether income should be taken, delayed, redirected, or left alone. That is what practical director planning looks like when it's done properly.
Your New Tax Year Action Plan Starting 6 April
A lot of directors breathe out on 6 April as if the pressure has gone. In reality, that's the best moment to take control.
When the new tax year opens, you have something valuable that disappears quickly: time. Time to plan income before it is paid. Time to shape dividends before they become routine. Time to decide how much of your strategy should come through salary, company contributions, or retained profit.
What to do in the first few weeks
You don't need a complex spreadsheet on day one. You do need a structured review.
- Rebuild your income plan: Decide what you want your mix of salary and dividends to look like for the new tax year.
- Check likely company profit: A remuneration plan that ignores expected trading reality won't hold up.
- Schedule pension thinking early: If pensions are part of your wider strategy, choose that intentionally rather than using them as a late fix.
- List major personal events: House moves, school fees, travel plans, or large purchases can all affect how much you need to draw.
- Review retained profit policy: Sometimes the smartest move is not extraction but keeping funds in the company for a defined reason.
Why early planning works better
Early planning gives you choices. Late planning gives you leftovers.
By the time March arrives, much of the year has already happened. Salary has been run. Dividends may already have been taken informally. Cash may already have been used elsewhere. Planning gets harder because options have narrowed.
A director who uses 6 April well is usually calmer by 5 April the following year. Not because tax has become simpler, but because fewer decisions are being made under pressure.
The start of the tax year is the cleanest point to design your year on purpose instead of discovering it by accident.
A better mindset for the year ahead
Don't think of tax planning as a once-a-year emergency. Think of it as a rolling process with one especially useful reset point.
The date new tax year starts matters because it gives you a clean edge. You can look at the company, look at your personal needs, and decide how the next twelve months should work before momentum takes over.
That is where directors usually make their best decisions.
Turning a Deadline into a Decision Point
The simple answer is that the UK tax year starts on 6 April and ends on 5 April the following year. For a limited company director, the more useful answer is that these dates shape when income lands, when planning opportunities close, and when a fresh strategy should begin.
The key skill is not memorising the date. It's understanding what sits on either side of it.
Your personal tax year runs on one timetable. Your company runs on another. Once you see those as separate clocks, a lot of confusion clears. Dividend timing makes more sense. Pension decisions become more deliberate. The rush around early April starts to feel less like chaos and more like a checkpoint.
That is the shift worth making. Stop treating 5 April as a panic deadline and 6 April as just another day in the diary. Use them as decision points.
If this has highlighted gaps in your current setup, that's useful. It usually means there is planning value in reviewing how you take income, how your company supports that, and whether your timing is doing what you think it is. Even small changes in sequence can make your year feel more organised and more intentional.
