The start of the new tax year warrants as much planning as the end of the old tax year.

While the end of the tax year on 5 April is a major focus of tax planning, it doesn’t end there. The following day may require much less immediate attention, but there is an argument for considering it to be just as important. For example:

• Personal allowances The personal allowance for 2025/26, the new tax year, remains at £12,570, the same as it has been since 2021/22. Above that level, income tax will normally enter the equation. If you (or your spouse/civil partner) do not have enough income to cover the personal allowance, then you could consider transferring investments between yourselves so that the income generated escapes tax. You should also consider whether or not to claim the marriage allowance if your partner pays no tax and you pay no more than the basic rate (or vice versa).
• At the opposite end of the income scale, once your income (after certain deductions) exceeds £100,000, you start losing your personal allowance at the rate of £1 for each £2 of excess. In those circumstances, a transfer of investments and the income generated can also make sense – this time by reducing your taxable income.
• Other tax allowances and bands Similar principles apply to other allowances, such as the personal savings allowance (up to £1,000), the dividend allowance (£500) and the thresholds of tax bands. It is much easier to shuffle around future income at the start of the tax year than attempt to do so as 5 April looms near.
• High income child benefit charge (HICBC) If you or your partner (marriage is irrelevant) have income (after certain allowances) of over £60,000 and both claim and receive payments of child benefit, then whichever of you has the higher income is taxed on that benefit. The tax charge is 1% of the child benefit for each £200 of income over the £60,000 threshold, meaning the tax matches the benefit at £80,000. If you have two children, this is equivalent to an extra 11.26% added to your marginal tax rate. Shifting your investment income could therefore save tax, even if you both pay the same marginal rate of tax.
