He’s already one of the most eligible bachelors in the world – and turning 30 will soon make Prince Harry even more of a catch.

Thanks to a legacy from Princess Diana, he will pocket more than £10million as he celebrates his birthday on September 15.

And even though he’ll face a hefty tax bill, there will be more than enough left to keep the playboy prince happy.

Harry could have to fork out around £4million in duty, but tax experts say he could limit it to £3.6million if he gives cash to charities.

When William got his own £10million share of his mum’s estate two years ago, 40 per cent went on inheritance tax.

A royal insider said: “There is no way Harry would dodge the tax.

“There are few similarities between the average person and Harry and William but when it comes to tax, they also have to pay their way.

“William got hit with a hefty bill when he turned 30 and so will Harry. His aides have to work out the most tax-efficient way for him to handle the money.”

Harry, now in Chile after flying to Brazil to see England’s World Cup exit on Tuesday, currently earns £38,847 a year as an Army captain.

He was just 12 when Diana was killed in a Paris road crash in 1997.

She left £12,966,022 which was reduced to £8,502,330 after death duties. But insiders believe the fund has now swelled to more than £20million thanks to clever investments by royal ­advisors.

The huge amount came from the ­settlement she got in her divorce from Prince Charles, shares, jewellery, cash, and personal items from her Kensington Palace home.

Diana shared her wealth equally between her two sons – even though William will inherit his father’s money-spinning Duchy of Cornwall when he becomes Prince of Wales.

Harry’s huge windfall comes as Buckingham Palace accounts show the Queen will receive an inflation-busting five per cent rise in public funding to £37.9million next year due to record profits from the Crown Estate.

It has also emerged that the cost of doing up William and Kate’s Kensington Palace home is costing taxpayers £4.5million.

Royal aides insist the monarchy still offers value for money at 56p per person a year.
