National Insurance Cardnational Insurance number card

If you are a resident of the UK and turn sixteen you will automatically be sent a National Insurance number in the post. if you have not received this, please call the contact number so it can be chased up for you. if you have reached the age of 20 and have not realised that you don’t have a National Insurance number, instead of calling the helpine, you need to visit your nearest Job Centre Plus and fill out an application form. Don’t worry, if you can prove you are a UK citizen but don’t have a National Insurance card, you can start work before the one you applied for is sent out. In some cases you may be asked to attend an interview to receive your National Insurance card. The interview will involve a series of questions such as why you need a National Insurance number and what your current circumstances are. It you do have to attend an interview you will need to take with you documents that prove your identity such as a passport, driving licence or ID card. Please note that HMRC no longer issue plastic cards, and your number is sent to you in a letter, as there is little use for the cards themselves. Your National Insurance number is so that any payments can be associated directly with you, without confusion as everyone’s number is unique to them.

Lost National Insurance Number

The main place you will find you National Insurance number will be on the card that was sent to you in the post. However, if you have misplaced this card, there are a number of other places where you can find your national Insurance number such as on your monthly payslip from your place of work as well as your p60 which you typically get when you leave a job. It may also be found on any tax letters you may have received. If you still cannot find your card or the number, you can call the National Insurance helpline where you will be asked a series of questions. Alternatively, you can visit the Government website where you can download a CA5403 form and send it to the address that is shown on the form. If you have done this and have received no response after two weeks, then please call the helpline. In recent years, HMRC has in fact stopped sending out the National Insurance plastic cards that once displayed your number, and so you will only need to ring or fill out a form to retrieve your number if you have no other means of reaching it. Your number will not be told to you over the phone, if you ring up to retrieve your number, it will be sent to you in the post. Call the helpline if you have requested your national insurance number and have not yet received it in the post.


National Insurance Calculator

Online calculators allow employers to see how much tax has been deducted from their pay roll, which includes National Insurance contributions. Tax begins being deducted from a person’s salary when they start to earn over £10, 600, which is soon to be risen to £11, 000, so anything that is earned below that is tax free. A tax deduction is calculated on the amount you earn, with the average person’s salary seeing a significant deduction to pay their taxes. You as an employee can also use the tax calculator to see how much tax you can expect to pay from your income and the tax calculator is mainly aimed at those that pay tax through the PAYE system (Pay As You Earn) as it will give an average reading to people who are paid using this method. There are instructions online on how to use the National Insurance calculator, where you can get a basic or more accurate reading depending on your age and how much information you provide but if you are having any issues using the calculator, please call the helpline.

When you are applying for a job or are starting a new job, you will be asked by the employer for a National Insurance number either on the application form or just given to your new employer in person/over email. Your employer will then need to check that National Insurance number. It is important that all National Insurance numbers are correct so the right person is paid by the company. To check it, they might perform a National Insurance verification request, if the payroll they are using within their company does not already have the facility to do this. if you are an employer that needs to take this action, you can find detailed guides online explaining how to verify the national Insurance number of any employee in your business. If you are struggling to do this, please call the National Insurance helpline.

About National Insurance

National Insurance is a type of tax paid by UK workers towards certain state benefits. It was established way back in 1911 but has naturally seen significant expansion and improvement by the likes of the Labour Government, since then. The main aim is to provide cash assistance to those who are sick, unemployed or retired. Your National Insurance contributions during your working life will ensure that you qualify for a state pension when you reach the qualifying age. Recent research has revealed that National Insurance does nowadays make up a significant part of Government revenue. National Insurance will be paid by a person in employment who is aged 16 or over and earning above £155 per week and will stop being paid when a person reaches state pension age, which at the moment stands at age 55.
