Question 1

What is the difference between gross pay and net pay?

Accepted Answer

**Gross pay** is what you earn before anything is taken off — the figure in your contract and in the job advert. **Net pay** is what actually reaches your bank account after deductions. The gap is often substantially larger than people expect when they see a salary figure.

**What sits between the two**, using the UK as the example:

**Income tax.** Charged in bands, with a personal allowance taxed at 0%, then progressively higher rates on income above each threshold. Crucially, **only the income within a band is taxed at that band's rate** — moving into a higher band does not increase the tax on everything you earned below it. The belief that a pay rise can leave you worse off is almost always wrong, though a small number of specific thresholds do create genuine cliff edges.

**National Insurance.** A separate contribution with its own thresholds and rates, funding state benefits and the state pension.

**Pension contributions.** Under auto-enrolment a percentage goes to your pension before or after tax depending on the scheme. This is deferred pay rather than a loss, and your employer usually adds their own contribution on top.

**Student loan repayments**, taken as a percentage of income above a plan-specific threshold.

**Other deductions** — salary sacrifice arrangements, cycle schemes, childcare vouchers, union dues, and any court-ordered attachment of earnings.

**Reading your payslip:** it should show gross, each deduction itemised, net, and year-to-date totals. Your tax code determines how much tax-free allowance is applied, and an incorrect code is a common cause of over- or underpayment — worth checking, since the responsibility for spotting it usually falls on you.

Thresholds and rates change each tax year and differ by country and region.

Question 5

What is a tax code, and why might mine be wrong?

Accepted Answer

A tax code tells your employer or pension provider how much tax-free income to give you before deducting tax. It is issued by HMRC, applied by your employer, and it is wrong more often than people

Question 6
