The government has published a table of rates and allowances (Annex A to the OOTLAR). The Tax Faculty will be publishing an updated version of our Tax rates and allowances summary.

Personal allowances

The intention to increase the personal allowance to £12,500 by 2020 was confirmed. 

The personal allowance in 2017/18 is £11,500. This will increase to £11,850 for 2018/19. 

Higher rate threshold

The intention to increase the higher rate tax threshold to £50,000 by 2020 was confirmed. 

The income tax 20% basic rate band for 2017/18 is £33,500 (with a 0% starting rate band of £5,000 for savings income in certain circumstances).

The 20% basic rate band will increase to £34,500 for 2018/19. As a result, the higher rate threshold (ie, the personal allowance plus the basic rate band) which is £45,000 in 2017/18 will be £46,350 in 2018/19.

In summary:

Year  Standard personal allowance Basic rate band of 20% on income Higher rate threshold Additional rate of 45% on income over

(*A lower higher rate threshold applies to earned income of Scottish taxpayers.)

Dividend allowance

The tax-free dividend allowance of £5,000 (more correctly described as a dividend nil rate band) was introduced from April 2016. As announced in the March 2017 Budget this is to be reduced to £2,000 from April 2018. No further changes to the taxation of dividends were announced in the Autumn 2017 Budget and the rates remain at 7.5%, 32.5% and 38.1% depending on the level of income.

National insurance

The NIC earnings limits have been uprated. The lower earnings limit will increase from £113 to £116 per week from April 2018. The primary and secondary thresholds will increase from £157 to £162 per week. The upper earnings limit will increase from £866 to £892 per week from April 2018.

For the self-employed, as announced earlier in November 2017, class 2 NIC will be abolished from April 2019 rather than April 2018 as previously planned. In the meantime the rate of class 2 increases to £2.95 per week from April 2018 (2017/18: £2.85) and the small profits threshold remains unchanged at £6,205 per annum. The lower and upper profits limits for class 4 NIC will increase from April 2018 to £8,424 (2017/18: £8,164) and £46,350 (2017/18: £45,000) respectively.

Capital gains tax

The CGT annual exemption for 2018/19 will be £11,700 (£5,850 for most trustees). This is an increase from £11,300 for 2017/18. There are no changes to the rates of CGT.

Property taxes

The lifetime allowance for pension savings will be £1,030,000 in 2018/19.

Corporation tax
