Corporation Tax returns for Cumnor micro companies
Corporation Tax is charged on a limited company’s taxable profit, not its accounting profit. The main rate is 25%, the small profits rate is 19% for profits up to £50,000, and profits between £50,000 and £250,000 pay the main rate less marginal relief. Getting the adjustments right, such as adding back depreciation, claiming capital allowances and removing disallowable expenses, is what keeps the bill accurate.
What is included
- A tax computation built from your accounts
- Capital allowances on equipment and vehicles
- A review of director expenses, loan accounts and benefits
- Trading losses claimed where they arise
- Return filed with HMRC and a payment reference sent to you

Cumnor is in the Vale of White Horse council area, in the South East region. Vale of White Horse has around 6,245 VAT- and PAYE-registered businesses, and 5,470 of them, about 88%, have fewer than ten employees (ONS UK Business Counts, 2026). That is the group the micro-entity rules were written for.
The largest groups of micro businesses in Vale of White Horse are professional, scientific and technical services (1,145), construction (850) and wholesale and retail (550). For professional, scientific and technical services companies in Cumnor, fee income, work in progress at the year end and how directors are paid are the key decisions, so we plan these with you before the accounts are finalised. That puts professional, scientific and technical services at 21% of the local micro-business base.
Zooming in, the ONS neighbourhood area around Cumnor (Vale of White Horse 001) has 355 VAT- or PAYE-registered businesses, and 330 of them (93%) are micro businesses.
Vale of White Horse ranks 650 of the 1105 areas we serve by number of micro businesses, and its micro share of 88% is in line with the 89% average across them. In construction (850 micro businesses in Vale of White Horse), Construction Industry Scheme deductions, retentions and stage payments can distort profit, so we reconcile your CIS statements before the accounts are prepared. In wholesale and retail (550 micro businesses in Vale of White Horse), closing stock and the VAT treatment of different product lines are the usual pressure points, so we value stock carefully and check your VAT records.
