Letter: A


Accounting Date: This is the final day in one's accounting period - usually the end of one's financial year. The date can be changed, but there are rules to be observed.

Accounting Period: The period on which one's accounts are based. Usually this includes the twelve months of one's financial year.

Additional Rate Tax: From the 2010-11 tax year, if you have earned more than £150,000 you will have to pay an additional rate of 50% tax on the amount above this level.

Age related allowances: Additional tax-free allowances available to individuals aged 65 and over in the tax year. These allowances will be restricted where the total taxable income exceeds the limits set for the year.

Allowances: These are tax-free amounts set by the government every year. Normally they are given to UK & commonwealth citizens, but are also available to others who qualify under specific rules. The basic and most common is the Personal Allowance -  it is available to everyone resident in the United Kingdom for tax purposes.

Anti-avoidance: Anti-avoidance rules are included in tax legislation in order to close any loopholes which may be used to avoid paying tax.

Annual Investment Allowance: You can claim a capital allowance called an Annual Investment Allowance (AIA) if you bought new equipment (but not cars) during the year up to an annual amount of £50,000. Add the cost of all the equipment together and, if the total cost is £50,000 or less, you can claim 100% of that whole amount as your AIA.

Appeals: An appeals procedure is laid down by law so that disagreements between a taxpayer and the HMRC can be settled by an independent tribunal. There is usually a given right of appeal against an HMRC decision. The appeal must be made within 30 days of the assessment or amendment, although late appeals may be accepted, and the grounds for the appeal must be stated. If there is no agreement, the appeal is usually heard by the General Commissioners, although some are heard by the Special Commissioners.

Approved Mileage Allowance Payments: AMAP is a way of calculating tax-free mileage expenses. An employer can pay up to 40p per mile for the first 10000 business miles and 25p per mile thereafter without any tax being due on the payment. If reimbursement is at less than these rates a claim for the remainder can be made.

At source: In terms of tax - where tax is deducted from income before it is effectively paid to the beneficiary. There are several schemes operating tax deducted at source, examples are: PAYE, Construction Industry Scheme (CIS4-CIS25), Non-resident landlord Scheme (NRL6), Tax on Interest
