They discuss payslips, tax codes, and national insurance. A payslip shows £1.40 national insurance; there is talk of changing tax code and opting out of pension. Behnam explains that the tax code 856L means an £8,560 tax-free allowance, but because the job started in January there are only about three months of pay, so no tax should be taken. They calculate that around £350 has been paid so far and there is room for about 11 more weeks of tax-free earnings, so they decide to leave the tax code unchanged.
