HMRC warning to check codes on letters as workers are owed £700 each – check if you’re affected
BRITS are being urged to check their tax codes immediately as thousands could be due a £700 refund from HMRC.
It comes as the May 31 deadline has passed for employers to issue P60 forms – a crucial document that confirms how much tax you’ve paid in the last financial year.
But tax experts are warning that many workers could be on the wrong tax code without even knowing it, potentially costing them hundreds of pounds.
One in three Brits has been on the wrong tax code at some point, with average overpayments hitting a hefty £689, according to research by Canada Life.
The blunder means HMRC could be sitting on billions in overpaid tax and the only way to get it back is to check your details and flag it.
Taxpayers should double check the ‘final tax code’ on their P60 that’s the string of letters and numbers near the top of the form.

Codes like "BR", "D0", or "D1" should raise a red flag.
These mean you may have been taxed at a flat rate with no tax-free allowance.
Anyone who stayed with the same employer up to April 5 should have already received their P60, either in the post or digitally.
And while it may be tempting to toss it aside, it’s an important piece of paperwork.

Those who’ve overpaid could see a refund land in their bank within five days once their claim is processed or receive a cheque in the post within two weeks.
But it’s not always good news, some may find they underpaid tax and owe HMRC money.
If that’s the case, most will be asked to repay it gradually over 12 months.
If you’re owed money, you may also receive a P800 letter or a simple assessment telling you how much you’re due and how to claim it.
There’s a four-year limit on claiming back overpaid tax, so if you think you've been overcharged, don’t delay.
