For UK limited company directors, the period before the 2025/26 tax year-end is a key opportunity to reduce tax and improve cash flow. Decisions made before 5 April can affect how much Corporation Tax your company pays and how efficiently profits are taken out of the business. Once the deadline passes, many of these options become unavailable.
Making tax planning decisions too late is a common mistake. When decisions are made during accounts preparation, salary levels, dividends, pension contributions, and expense timing are often already fixed, which can result in missed reliefs and higher tax bills than necessary.
The strategies in this guide are legal, practical, and fully compliant with HMRC rules. They focus on using timing and existing allowances sensibly, showing that effective year-end tax planning is usually about early action rather than complexity.
Strategy 1: Optimise Salary vs Dividends Before 5 April
For most limited company directors, income is taken through a combination of salary and dividends, and each is taxed in a very different way. Salary is subject to Income Tax and National Insurance for both the director and the company, while dividends are paid from post-Corporation-Tax profits and do not attract National Insurance.
Because of this, even small changes to the mix can have a noticeable impact on your overall tax position.
Key points to consider before the 5 April year-end include:
- Salary is often set around National Insurance thresholds to protect State Pension entitlement while keeping NIC costs low
- Dividends are usually more tax-efficient for additional income, but they are taxed based on your total income for the year
- An increase in salary can make sense if company profits are lower, pensionable earnings need to rise, or dividend tax rates are higher.
- Declaring dividends before April 5 can help use unused dividend allowances or basic rate bands rather than lose them.
For example, a director who has taken a modest salary may find that declaring an additional dividend before year-end keeps them within a lower dividend tax band, whereas waiting until the next tax year could mean paying more tax on the same amount. The right approach depends on personal income, company profits, and future plans, which is why there is no single salary and dividend split that works for everyone.
A quick review with limited company accountants can help fine-tune your salary and dividend mix before deadlines hit. After extracting profits efficiently, the next step involves exploring more tax-efficient ways to invest company funds.
Strategy 2: Make Pension Contributions Using Company Profits
Using company profits to make pension contributions is one of the most tax-efficient planning tools available for limited company directors. Employer pension contributions are usually treated as an allowable business expense, which means they can reduce your company’s taxable profits and, in turn, lower your Corporation Tax bill. At the same time, the money goes toward your long-term retirement rather than being lost to tax.
Before the 5 April year-end, directors should review the following points:
- Employer pension contributions are normally deductible for Corporation Tax, provided they are made wholly and exclusively for business purposes.
- Company pension payments are usually more tax-efficient than personal contributions, as they avoid Income Tax and National Insurance.
- Most directors can contribute up to the annual allowance, with unused allowances from the previous three tax years potentially available through carry forward.
- Contributions must be paid into the pension scheme before year-end to count for that tax year.
- A common mistake is authorising contributions but missing the payment deadline, which delays tax relief.
From a compliance perspective, documentation matters. Pension contributions should be recorded in the company’s books and, if necessary, backed up by board decisions. They should also be directly related to the director’s job in the company. HMRC may challenge contributions that appear excessive or lack a clear business rationale, especially if paperwork is incomplete.
Once pension allowances have been reviewed and used where appropriate, the next area to consider is whether asset purchases before year-end could unlock further tax relief through capital allowances.
Strategy 3: Use Capital Allowances Before Year-End
Capital allowances allow limited companies to deduct the cost of certain business assets from taxable profits, reducing Corporation Tax for the year. Reviewing planned purchases before the year-end can make a real difference, as relief is usually only available once the asset has been bought and put into use by the company.
Before making any purchases, it helps to understand what qualifies:
- Capital allowances typically apply to plant and machinery, such as IT equipment, tools, office furniture, and certain vehicles
- The Annual Investment Allowance (AIA) lets most businesses deduct the full cost of qualifying assets up to the annual limit in the year of purchase
- Computers, servers, and other IT equipment usually qualify, making year-end upgrades a common planning step
- Vehicles have special rules, with electric cars and low-emission vehicles often qualifying for more generous allowances
- The business must purchase and use the asset before the end of the accounting period to qualify for relief.
There are also some practical risks to watch out for. Assets bought personally and later used by the company may not qualify in the same way as items purchased directly by the company. It’s also important not to buy equipment purely for tax reasons if it is not genuinely needed for the business. HMRC can deny relief where purchases lack a clear business purpose or are incorrectly treated in the accounts.
Once capital allowances have been considered, the next step in year-end planning is looking at how the timing of income and expenses can further manage taxable profits.
Looking ahead also helps with compliance. Our MTD for Income Tax 2026 guide explains what’s changing and why early planning avoids last-minute stress
Strategy 4: Manage the Timing of Income and Expenses
Managing when income and expenses fall is a practical way for limited companies to control taxable profits while staying within the rules. The focus should always be on normal commercial activity, supported by proper records, rather than artificial adjustments made only to reduce tax.
Accelerate allowable expenses before year-end
Bringing forward genuine business expenses can increase deductions in the current accounting period. This may include routine costs such as professional fees, software subscriptions, insurance, or rent, provided they relate to the period and are allowed under accrual accounting. Corporation Tax is based on when costs are incurred, not simply when cash leaves the bank.
Defer income when commercially appropriate
In some cases, income can be pushed into the next accounting period if the work is completed after year-end or if contracts allow later invoicing. It is important that any deferral reflects the reality of the work done, as HMRC may challenge income moved purely to reduce tax.
Understand accruals versus cash flow
Many directors focus on bank balances, but taxable profits are calculated on an accruals basis. This means invoices raised, work completed, and expenses incurred matter more than when money is received or paid. Reviewing accruals before year-end helps avoid surprises in the final tax bill.
Example of how timing affects Corporation Tax
If a company plans to renew an annual software licence in April, paying and incurring that cost before year-end may allow it to be deducted in the current period, reducing taxable profits. Similarly, delaying invoicing for work genuinely completed after year-end can shift income into the next period, lowering the current Corporation Tax liability.
Once income and expenses have been reviewed, the final area to address is how profits are extracted before year-end without triggering avoidable tax charges.

Strategy 5: Review Director Loans and Dividends Before Filing
Director’s loan accounts are a common area where limited company directors face unexpected tax charges. When the company takes money that is not salary, dividends, or reimbursed expenses, it results in a director’s loan. Not reviewing these balances before year-end can lead to tax and compliance issues for the company.
Key points to review before filing include:
- A director’s loan account becomes overdrawn when withdrawals exceed salary, dividends, or repayments.
- Overdrawn balances at year-end can trigger additional tax if not cleared within the required timeframe.
- Section 455 tax applies when loans remain outstanding, creating a temporary corporation tax charge for the company.
- Overdrawn loans can often be cleared with dividends or salary, provided there are sufficient profits and the timing is correct.
- Dividends must be properly declared, and salaries must be processed through payroll for them to be valid.
- Accurate records and supporting documentation are essential to avoid challenges from HMRC.
Online Accountants can spot director loan issues early and help resolve them before penalties apply. With director loans and dividends reviewed, the focus can shift to pulling all planning steps together into a clear year-end checklist.

Final Year-End Tax Planning Checklist for Directors
Before the 2025/26 tax year-end, limited company directors should step back and review the key areas that most often affect their final tax bill. Before deadlines lock in decisions, a simple checklist can ensure you don’t miss anything important.
Use this year-end checklist as a final sense check:
- Salary and dividend levels are reviewed to ensure they remain tax-efficient for both the company and the director.
- Pension contributions assessed and paid in time to secure Corporation Tax relief.
- Planned asset purchases are reviewed to confirm whether capital allowances can be claimed.
- Income and expenses are checked to ensure they fall into the correct accounting period.
- Director loan accounts were reviewed and cleared where needed to avoid unexpected tax charges.
Completing this review before year-end provides clarity and reduces the risk of last-minute surprises. With the main planning areas covered, directors can approach filing with confidence, knowing their tax position reflects deliberate choices rather than rushed decisions.

Wrapping Up
Year-end tax planning for limited companies is not about loopholes or aggressive tactics. It is about understanding the rules, using available allowances correctly, and making decisions at the right time. In many cases, small actions taken before 5 April can have a meaningful impact on both Corporation Tax and personal tax outcomes.
Leaving planning until filing time often removes flexibility and increases the risk of surprises. Reviewing salary and dividends, pension contributions, asset purchases, income timing, and director loan balances early gives directors more control and clearer options.
If you want clarity before deadlines approach, a short year-end review with experienced Limited Company Accountants can make the difference between rushed compliance and confident, well-planned filing.
FAQs
When should UK limited companies start tax planning?
Ideally, tax planning should start several months before the 5 April year-end. Early planning allows directors more flexibility to adjust salary, dividends, pension contributions, and spending decisions without rushing or risking mistakes close to deadlines.
Can year-end tax planning reduce Corporation Tax legally?
Yes. When done correctly, year-end tax planning is fully compliant with HMRC rules. It focuses on using existing allowances, reliefs, and timing rules as intended, rather than aggressive or artificial arrangements.
Are pension contributions better than dividends for tax?
In many cases, company pension contributions are more tax-efficient because they can reduce Corporation Tax and avoid Income Tax and National Insurance. However, whether they are better than dividends depends on personal income levels, future retirement plans, and cash flow needs.
Can Online Accountants handle year-end tax planning remotely?
Yes. Many limited company directors work with Online Accountants to review their tax position, model different scenarios, and handle compliance remotely, often with real-time data and digital records.
What happens if I miss year-end planning opportunities?
Most year-end planning options cannot be backdated once the deadline has passed. Missing these opportunities can mean paying more tax than necessary and having fewer options available when accounts and returns are prepared.
