Peter took £60,000 from his pension. The tax deducted was £25,379. The right amount was £11,432. Nobody made a mistake.
He retired in the spring at 62, and this was his first taxable withdrawal: £60,000 to clear the mortgage and sort out the kitchen, with no other taxable income this year.
On those facts the full-year tax comes to £11,432.
What actually left the payment was £25,379.
That's not an error, and it isn't the provider being difficult. A first withdrawal usually arrives before the provider holds a proper tax code, so it's taxed on what's called an emergency basis. In plain terms, the system assumes the £60,000 is the first of twelve identical monthly payments, and gives Peter one month's worth of allowances instead of a year's worth.
One twelfth of his tax-free allowance. One twelfth of the 20% band. One twelfth of the 40% band. The rest of the payment, over £48,000 of it, taxed at 45%.
So Peter is £13,947 short at exactly the moment he'd planned to spend the money.
He does get it back.
There's a claim that takes a few weeks, or HMRC settles up automatically after the tax year ends. Between April and June this year HMRC repaid £50.35 million of exactly this tax, across more than 12,600 claim forms. That's an average of about £3,993 a time, sitting with HMRC instead of with the people who'd earmarked it.
Here's the part almost nobody is told. A lot of that queue was avoidable. A small first withdrawal, taken early and well ahead of the main one, gets a live tax code onto the provider's records.
The main payment is then taxed with a proper share of the year's allowances behind it rather than one month's worth. The later in the tax year it lands, the closer it comes to the right figure, and a March payment can come out right to the pound.
Same pension, same money, same tax year. In one order it's £13,947 light on the day it matters. In the other, the gap shrinks, and with the timing right it disappears.
The withdrawal is rarely the mistake. The sequence is.
