Emergency Tax Code Numbers

What are Emergency Tax Code Numbers?

Emergency tax codes are temporary tax codes issued by HMRC when they don't have enough information to assign you a personal tax allowance. They are used to calculate the tax on your income until HMRC can issue a correct tax code. Emergency tax codes usually have the format 1250L or 1250 M, where 1250 is the tax-free allowance and L or M denotes the tax year.

When Do Emergency Tax Codes Apply?

Emergency tax codes are typically issued when you start a new job, change jobs, or have changes in your personal circumstances that HMRC isn't yet aware of, such as a change in residential status or a new benefit-in-kind. They can also be issued if HMRC needs more time to confirm your employment details or update your tax record due to administrative errors.

In the context of emergencies, these codes may apply when you've recently changed jobs or started working due to an urgent need for income, for example, during a financial crisis or a significant life change like divorce or the death of a partner.

Emergency tax codes can significantly impact your take-home pay. Since these codes assume you're a basic rate taxpayer, they may lead to an overpayment of tax, particularly if you're entitled to a tax allowance or other tax reductions. This can result in a lower net income and potentially leave you out of pocket.

On the other hand, if you're on a low income or not working full-time, an emergency tax code could mean you pay too much tax. In this case, you might be due a tax refund.
