What is an emergency tax?
An emergency tax code is applied to your salary by HMRC. It is only a temporary measure until the tax office has more information about you. Once they have the relevant information, your tax code is adjusted.

Why am I on an emergency code?
You are usually placed on emergency tax when you start a new job, or if you are starting your first ever job, in this case, HMRC will have no financial information about you, so an emergency tax code will be applied automatically. Other reasons may include that you have started, or stopped receiving work benefits, you have started a full-time job after being self-employed, or you claim marriage allowance or expenses.
How do I know if I am on emergency tax?
An emergency tax code will be on your payslip. Different companies use different play slip templates, but you can generally find your tax code near your national insurance number. Over the course of the year, HMRC will adjust how much tax you pay as it gathers more financial information about you. Though the payments are corrected over the year, you may still have paid too much tax, and you can claim a tax refund.
How much is emergency tax?
Emergency tax means you are paying more than the basic UK tax rate. A basic rate taxpayer will pay an extra £1,300 in taxes if they earn up to £45,000, while higher-rate taxpayers will pay an extra £4,600 in taxes if they are earning up to £100,000. Anyone over £100,00 per year begins to lose personal allowance by £1 for every £2 they earn over that number, at over £123,000 you do not get any personal allowance.
