It is a director drawing dividends past the point where the £500 dividend allowance and the basic rate band stop absorbing them, and finding a January bill nobody budgeted for. It is income crossing £100,000, where the personal allowance tapers away at £1 for every £2 above the threshold and the effective marginal rate on that band is far higher than the headline. It is a landlord still deducting mortgage interest as an expense rather than claiming the basic rate tax reducer. It is a capital gain reported without using the annual exempt amount, or a residential property gain missed entirely, which carries its own 60-day reporting deadline separate from the return.\u003C\u002Fp>\n        \u003Cp style=\"color:var(--muted);font-size:17px;line-height:1.6;margin-bottom:18px;\">A worked example. A director on a £12,570 salary taking £60,000 of dividends has £500 covered by the dividend allowance, part of the remainder taxed at the ordinary rate and the balance at the upper rate once total income passes the basic rate band. Shift £10,000 of that into an employer pension contribution before 5 April and the company saves Corporation Tax on it while the personal bill falls. Do the same thing on 6 April and you have waited a year for the benefit.
