The facts to know
What is a National Insurance number for?
To record the tax and National Insurance you pay.
A National Insurance number is a unique personal reference that keeps track of the tax and National Insurance contributions recorded against your name throughout your working life. It is not, on its own, proof that you're allowed to work in the UK. That's a separate check employers must do.
Why it matters: Many people wrongly assume a National Insurance number proves the right to work, which the exam specifically corrects.
Memory hook: NI number: tracks your contributions, doesn't prove your right to work.

When are young people in the UK sent a National Insurance number?
Just before their 16th birthday.
You don't have to apply for a National Insurance number as a teenager living in the UK. It's sent to you automatically, shortly before you turn 16. This is well before most people start working, so the number is ready and waiting for when a first job eventually comes along.
Why it matters: The age is asked precisely, and it is easy to confuse with the age you can start work.
Memory hook: Sweet sixteen, almost: your NI number arrives just before the big birthday.

Which government department collects taxes in the UK?
HM Revenue & Customs (HMRC).
HM Revenue & Customs, usually shortened to HMRC, is the government department responsible for collecting taxes in the UK. The money it collects, especially income tax, funds everyday public services such as roads, schools, the police and the armed forces, the practical link between paying tax and public life.
Why it matters: HMRC is a name you'll need to recognise instantly, because the wrong answers name similar-sounding but incorrect departments.
Memory hook: HMRC: Her Majesty's tax collectors, funding the roads you drive on.

What is the system called where an employer takes income tax directly from your pay?
Pay As You Earn (PAYE).
Most employees never have to work out their own tax bill, because their employer takes the correct income tax straight out of their wages before they're paid, and sends it to HMRC directly. This automatic system is called Pay As You Earn, or PAYE for short, and it runs every payday.
Why it matters: PAYE is the default system for most workers, so understanding it helps you contrast it with self-assessment for the self-employed.
Memory hook: PAYE: Pay As You Earn, tax taken before it even reaches your pocket.

How do self-employed people in the UK pay their tax?
Through self-assessment, by completing a tax return.
Self-employed people don't have an employer to deduct tax automatically, so they must work it out and pay it themselves through a system called self-assessment. This means filling in a tax return each year, declaring income and expenses, and sending the payment directly to HMRC rather than having it taken from wages.
Why it matters: It's the direct opposite of PAYE, and the test likes contrasting the two systems.
Memory hook: Self-employed, self-assessed. No boss to do it for you.
