Income Tax – An introduction
A brief history
Income Tax has a long history. It was first announced in 1798 and introduced in 1799 by the then Prime Minister, William Pitt the Younger, to help pay for the war against France under Napoleon. The tax raised almost £6 million in its first year. The tax was repealed a number of times in the early years but the foundations of Income Tax as we know it were laid by Pitt’s successor, Henry Addington, who brought in the Addington Act which introduced two major innovations:
Taxation at source – for example, the Bank of England deducting Income Tax when paying interest to holders of gilts.
Although there have been many changes since the Addington Act of 1803, it set a precedent to tax individuals that continues to this day!
Income Tax is a tax paid on taxable income received by individuals including:
There are certain types of income which are not taxable such as:
These income sources are ignored when calculating the amount of Income Tax payable.Individuals can be liable to Income Tax at any age and there are special rules to stop parents avoiding tax by putting assets into their children’s names.
Most individuals in the UK have a personal allowance threshold which is the amount of taxable income they are allowed to earn annually without being taxed.
The basic personal allowance for the tax year commencing 6 April 2018 is £11,850. The higher age related allowances for older individuals have now been phased out.
There remains a blind person’s allowance and a married couple’s allowance where one of the spouses was born before 6 April 1935.
The personal allowance is gradually reduced by £1 for every £2 of income over £100,000 irrespective of age.
The marriage allowance came into force on 6 April 2015 and applies to married couples and those in a civil partnership where a spouse or civil partner doesn’t pay tax or doesn’t pay tax above the basic rate threshold for Income Tax (i.e. one of the couples must currently earn less than the £11,850 personal allowance for 2018-19).
The allowance permits the lower earning partner to transfer up to £1,190 (2017-18: £1,150) of their unused personal tax-free allowance to a spouse or civil partner. This could result in an annual saving of up to £239 for the recipient (20% of £1,190).
Income Tax rates
After personal allowances are calculated, the amount of Income Tax payable depends on the level of income, the type of income and the Income Tax rates. The Income Tax rates for 2018-19 and 2017-18 are as follows:
For basic rate taxpayers the first £1,000 interest on savings income will be tax-free. For higher rate taxpayers the tax-free personal savings allowance will be £500. Anyone earning over £150,000 will not benefit from the personal savings allowance.
The High Income Child Benefit charge applies to taxpayers whose income exceeds £50,000 in a tax year and who are in receipt of Child Benefit. The charge either reduces or removes the financial benefit of receiving Child Benefit. Where both partners have an income that exceeds £50,000, the charge applies only to the partner with the highest income.
The Child Benefit charge is charged at the rate of 1% of the full Child Benefit award for each £100 of income between £50,000 and £60,000. For taxpayers with income above £60,000, the amount of the charge will equal the amount of Child Benefit received. Taxpayers affected by the change have the choice to keep receiving Child Benefit and pay the tax charge through Self Assessment, or elect to stop receiving Child Benefit and not pay the new charge.
A new dividend allowance was introduced in April 2016 and replaced the non-refundable dividend tax credit of 10%. The first £2,000 (2017-18: £5,000) of dividend income received is tax free regardless of the amount of non-dividend income.
However, dividends in excess of the £5,000 allowance will be taxed at the following new rates based on the recipient’s highest rate of Income Tax:
Dividends received within the £2,000 allowance will still count towards the basic or higher rate bands and may therefore affect the rate of tax paid on dividends received in excess of the £2,000 allowance. Dividends received by pension funds and dividends received on shares held in an ISA continue to be tax-free.
Income Tax is also due on certain non-cash benefits received from an employer including:
The rules for obtaining tax relief for business related expenditure incurred by employees are notoriously restrictive.
Paying Income Tax
Taxpayers who are employed usually have most, if not all, of their tax collected using the Pay as You Earn (PAYE) system. The employer will deduct tax using a tax code determined by HMRC to calculate how much tax should be paid.
In most cases, basic rate tax is also deducted on interest received from banks and building societies.
Taxpayers who are company directors, self-employed or who have complex tax affairs will need to file Self Assessment tax returns and pay their tax through the Self Assessment tax system. This is a special process with its own rules that can be found in one of our other guides.
National insurance is a separate tax (or contribution) payable in addition to Income Tax. National insurance contributions are meant to fund social security benefits such as an entitlement to the state pension. The amount of National Insurance payable by taxpayers depends on the level of income and their employment status.
Claiming Tax Relief
There are a number of tax reliefs which can reduce the amount of Income Tax due. These reliefs mainly relate to gifts to charities using Gift Aid, pension contributions and employees using their own car for business mileage.
