Millions of workers urged to check key code on special payment slips arriving in DAYS – check if you’re overpaying

MILLIONS of workers have been urged to check a key code on a special payment slip revealing if they're overpaying tax.
The warning has been issued to employees who should receive their P60s before the end of the month.
P60s are issued to workers at the end of every tax year with the final deadline for bosses to send them May 31.
They are sent out either electronically or in paper form.
However, one key detail on the P60 could tell you you're paying the wrong amount of tax - your "final tax code".
If it turns out you are on the wrong code, it means you could be overpaying tax and are owed money from HMRC.
Bear in mind though, you may also be underpaying tax and have to pay HMRC any shortfall.
Sarah Coles, personal finance expert at Hargreaves Lansdown, said: "It isn’t always easy to get to grips with your P60, but the thing to look for is the final tax code.
"If it’s wrong, you could end up over-paying or under-paying your tax – either of which is a pain in the neck."
Your tax code could be wrong for any number of reasons, including if you have multiple jobs and your employer doesn't know your personal allowance has been used up from earnings elsewhere.
You may also be on the wrong code if you've changed jobs and your employer hasn't received the right documentation from a previous employer.
Or, someone in the HR department might simply have made a clerical error meaning you're on the wrong code.
A tax code is normally a five-digit mixture of letters and numbers. The most common tax code for the current tax year is 1257L.
This tax code is used for most people with one job and no untaxed income, unpaid tax or taxable benefits (like a company car).
You can check your tax code on your online personal tax account, via payslips, or on the HMRC app.
You can also, if you've received one, check your code on a "Tax Code Notice" letter from HMRC.
You'll need your Government Gateway ID and password to log in to your online personal tax account.
If you don't have this you can use your National Insurance number or postcode and two of the following:
You can also use which can give you a steer as to whether you're on the right one.
If, after checking, you think you're on the wrong tax code, you can contact HMRC to tell them via phone on 0300 200 3300.
This is usually the quickest way to get a response.
Or, you can send a letter to the following address: Pay as You Earn and Self Assessment, HM Revenue and Customs, BX9 1AS, United Kingdom.
If you are on the wrong tax code and have been paying too much, HMRC will change it so you pay the correct amount moving forwards.
They should also reimburse any tax you've already overpaid.
If you've been underpaying tax, you will usually have to pay the money back over 12 months.
But, only if you are earning enough over the personal tax allowance (£12,570) to cover the underpayment and owe less than £3,000.
HMRC might get in touch with you to tell you you're owed a tax rebate too - they'll do this via a P800 letter or a simple assessment letter in the post.
But again, a P800 might tell you if you've not paid enough tax and have to pay it back.
A P800 letter will tell you if you can claim online through the Government's website, in which case you'll need your Government Gateway ID and password.
If you claim the money online it will be sent to your bank account within five days.
You can also claim your refund through the HMRC app.
If your P800 letter states you will be paid your tax rebate via cheque in the post, you should receive it within 14 days of the date on your letter.
If you're owed tax from more than one year, you'll get a single cheque for the entire amount.
There are time limits in place to reclaim any overpaid tax, which is currently four years from the end of the tax year in which you are trying to claim.
So, if you're in any doubt you've overpaid tax, you should contact HMRC as early as possible.
Your tax code is a combination of letters and numbers.
The number will normally dictate the level of your tax-free allowance. So if your allowance is £11,000 the first four digits of your code will be 1100.
The letters have different meanings - here is a guide:
If your tax code begins with 'W1', 'M1' or 'X' you've been placed on an emergency tax code and may need to update your details.
If you change jobs, take on an additional role or have another change in circumstances it is also worth checking your details and making sure you are on the correct code.
It could be that HMRC has not received information about your change of circumstances and therefore will not update anything.
