Before 5 April: The Year-End Checklist That Could Save You Thousands

Why the Deadline Punishes the Unprepared

Every tax year ends the same way: abruptly. On 5 April, allowances reset, elections close and planning opportunities that existed in February vanish overnight. The conversations that needed to happen in January — with your accountant, your pension adviser, your bank, your key people — are precisely the ones that get deferred, and the cost of deferral is rarely trivial. Some of the items below are worth thousands of pounds a year; others protect relationships that money cannot replace.

Here are the seven conversations worth having while there is still time to act.

1. Your Accountant: Dividends Versus Salary

For owner-managers of limited companies, the split between salary and dividends remains one of the most effective planning levers — and one of the most time-sensitive. Salary must be processed through payroll before the year ends to count, and dividend decisions require available profits and proper paperwork dated within the tax year.

Leave it too late and your options narrow to whatever the payroll can process in time. The realistic benefit of getting the balance right depends on your profit level and other income, but for many owner-managers the difference between a considered split and a default arrangement runs into four figures annually. Ask specifically about the optimal salary threshold, the availability of your dividend allowance, and whether your company's profits support a final distribution before 5 April.

2. Your Pension Adviser: Allowances That Don't Roll Over

Annual pension allowances are use-it-or-lose-it in most cases. The annual allowance currently sits at £60,000 for most individuals, with carry-forward allowing unused allowance from the previous three tax years to be tapped — but only if contributions are made before the deadline.

Higher earners affected by the tapered allowance, and anyone who has recently seen a step change in income, should check their position now rather than in April. A contribution that uses carry-forward can shelter a substantial sum from tax that would otherwise be payable at 40% or 45%. The deadline risk is absolute: a contribution intended for one tax year but paid after 5 April generally cannot be backdated.

3. Your Accountant Again: Capital Allowances and Equipment

If your business has been contemplating equipment, vehicles or technology purchases, the timing question is live. Full expensing allows qualifying plant and machinery to be deducted from taxable profits in full in the year of purchase — but the asset must be in use before the year ends. A purchase agreement signed on 4 April with delivery in May may achieve very little. Ask whether a planned capital spend should be accelerated, and what the cashflow implications are of doing so.

4. Your Bank: Facilities Before You Need Them

Banks lend most willingly to businesses that don't urgently need the money. An annual review of your overdraft headroom, invoice finance limits and any revolving facility is best done before the year end, when your latest accounts are fresh and your trading position is documented.

The deadline risk here is softer but real: a seasonal cashflow squeeze in the new tax year is far harder to fund reactively than proactively. The realistic benefit is not a tax saving but optionality — the ability to act on opportunities or absorb shocks without a scramble.

5. Your Key Staff: Retention Incentives With a Tax Year Clock

Bonuses, share awards and salary sacrifice arrangements all interact with the tax year. If you are planning a retention bonus or considering a share-based incentive, the mechanics differ depending on whether it is implemented before or after 5 April. Salary sacrifice arrangements — for pensions, electric vehicles or additional holiday — need to be varied in employment terms and processed through payroll before the year closes.

The risk of delay is twofold: the tax efficiency may be deferred by a full year, and a promised incentive that slips can do more harm to morale than no promise at all.

6. Your Spouse or Partner: The Household Position

Less glamorous, frequently overlooked. The marriage allowance can transfer up to £1,260 of personal allowance between partners where one is a basic-rate taxpayer and the other has unused allowance — worth up to £252 a year, and claims can be backdated, but only so far. More significantly, review who holds income-producing assets: dividend and savings income sitting with the higher-rate taxpayer in a household where the other partner pays basic-rate tax is a permanent leak that no April scramble can repair.

7. Yourself: The Position Review

Finally, set aside an hour to look at the whole picture — company profits, personal income, pension positions, capital gains realised in the year, and any upcoming disposals. Isolated decisions made without the full picture are how allowances get wasted. Most accountants will run a year-end planning review if asked by early March; ask in April and you will be booking it for next year.

The Pattern Behind the Checklist

Notice what all seven conversations have in common: none can be meaningfully executed after the deadline. Tax planning is not about cleverness in the final week; it is about sequencing ordinary decisions early enough that they land in the right tax year.
