£51,000 after tax

A salary of £51,000 gives you £40,141 a year after tax, which works out at £3,345.08 a month. Only about seven hundred and thirty pounds of it sits above £50,279, so in England, Wales and Northern Ireland the higher rate reaches a very thin slice of your pay.

How this was worked out

1. Salary: £51,000
2. Personal allowance: £12,570. Payroll applies it as tax code 1257L, which gives £12,579 of tax-free pay.
3. Taxable income: £51,000 − £12,579 = £38,421
4. Basic rate: £37,700 × 20% = £7,540
5. Higher rate: £721 × 40% = £288.40
6. Income tax: £7,828.40
7. National Insurance: (£50,270 − £12,570) × 8% = £3,016, plus (£51,000 − £50,270) × 2% = £14.60, total £3,030.60
8. Take-home pay: £51,000 − £7,828.40 − £3,030.60 = £40,141

Seven hundred pounds over the line

Income tax on this salary comes to £7,828.40. The personal allowance of £12,570 comes off first and leaves £38,421 of taxable pay. Almost all of that is in the basic rate band at 20%. The small remainder above the band limit of £37,700 is charged at 40%, which adds under three hundred pounds to the bill.

National Insurance on £51,000 comes to £3,030.60. The main rate of 8% covers pay from £12,570 up to £50,270, and the thin slice that pays higher rate tax pays National Insurance at just 2%. Your next thousand pounds of pay is therefore worth £580 after deductions, a marginal rate of 42%.

A pension that pulls you back into the basic band

A five per cent salary sacrifice moves £2,550 into your pension. That sum is bigger than the part of your salary above the higher rate threshold, so after the sacrifice all of your taxable pay is back inside the basic rate band. Take-home falls by £1,735.60, to £38,405.40. With the sacrifice in place, a raise loses only 26.6% to tax and National Insurance, because five per cent of it goes into the pension and the rest stays in the basic rate band.

A net pay or relief at source scheme puts the same five per cent into the pension but leaves you £38,245.20, which is £160.20 less, since only salary sacrifice also cuts National Insurance. Your employer pays £6,900 of its own National Insurance on this salary, and salary sacrifice lowers that by £382.50.

Scotland and student loans

In Scotland, £51,000 leaves £38,571.13 a year, £1,569.87 less than elsewhere in the UK. The Scottish higher rate of 42% begins above £43,671, so a Scottish taxpayer on this salary pays it on more than seven thousand pounds of income. All four undergraduate loan plans take a repayment here. Plan 5 takes the most at £2,340, and Plan 4 the least at £1,548. The page for fifty thousand pounds shows a salary with no higher rate slice at all.
