What Is The Meaning Of An Emergency Tax Code?

An emergency tax code means that the tax code applies to a specific period during the year and not the entire tax term. Emergency codes are temporary and unlike regular tax codes, they can change in the middle of the tax term if there is a change in circumstance or income(s) of the individual to that they are being applied.

An emergency tax code such as OTW1 or OTM1 can apply in the following situations:

  • the individual is changing jobs and has been assigned a new tax code in the middle of the tax term 
  • the individual was previously self-employed and is returning to a salaried job 
  • the individual is returning to the workplace after a career sabbatical

The W1 extension indicates that the tax code is being applied for a particular week in question (this applies in the case of weekly wages which can change over time). Similarly, the M1 extension indicates that the tax code only applies to the month in which is being assigned and not the entire tax term.

What Is The Meaning Of A Basic Rate Tax Code?

The basic rate tax code is also an emergency tax code and is read as BRX. if you see a basic rate tax code on your payslip it means that all your earnings must be taxed at the basic rate of 20% without taking into consideration your tax-free Personal Allowance. 

It is usually applied when the HMRC and your employer do not have complete details regarding your employment and/or income details and the BRX tax code is assigned to you while the documentation is complete and a permanent tax code can be assigned to you.

In addition to this, a BRX tax code is assigned if:

  • an individual has not provided their employer with a complete P45 form or a P47
  • someone is being transferred from being self-employed to a PAYE employee
  • you are receiving an additional income through a second job or a pension

What Is The Meaning Of A Non-Cumulative Tax Code?

A non-cumulative tax code means that the HMRC is only taking into account the period in question for your tax calculation and deduction and not the entire tax term. This is usually a temporary or emergency tax code which will change before the end of the tax term when a permanent tax code is assigned to you.

A non-cumulative tax code indicates that your income will be taxed depending on whether you receive your pay on a weekly or monthly basis. In the case of weekly pay, you will find a W1 extension at the end of your tax code; while for a monthly salary, your tax code will end with an M1 extension.

This means that the income tax rate is applied to the entire sum of income(s) of an individual without the deduction of Personal Allowance from their earnings. 

What Is The Meaning Of A Cumulative Tax Code?

A cumulative tax code is the most common tax code that applies in simple cases of tax codes assigned to earnings. It is calculated on the basis of your year-to-date tax payments. 

This means that the cumulative tax code takes into account your tax payments made during a tax year while keeping an account of the amount of tax-free allowance that you have used during the same time. This means that any unused personal allowance can be passed on to future weeks.

The most commonly used cumulative tax code is 1257L. It indicates your tax-free personal allowance of 12,570 and that income earned above this amount will be subject to a tax deduction.
