CT600 tax return filing in Ilminster

CT600 filing for Ilminster limited companies

The CT600 is the company tax return form. It is filed online and has to be accompanied by the full statutory accounts and a tax computation in iXBRL format. Filing the CT600 with HMRC is a separate duty from filing accounts at Companies House, even though most companies deal with both in the same week.

CT600 filing service for Ilminster businesses: local facts

Ilminster is in the Somerset council area, in the South West region. Somerset has around 24,665 VAT- and PAYE-registered businesses, and 22,160 of them, about 90%, 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 Somerset are construction (3,515), agriculture, forestry and fishing (3,430) and professional, scientific and technical services (2,900). For construction companies in Ilminster, Construction Industry Scheme deductions, retentions and stage payments can distort profit, so we reconcile your CIS statements before the accounts are prepared. That puts construction at 16% of the local micro-business base.

Zooming in, the ONS neighbourhood area around Ilminster (South Somerset 019) has 415 VAT- or PAYE-registered businesses, and 365 of them (88%) are micro businesses.

Somerset ranks 90 of the 1105 areas we serve by number of micro businesses, and its micro share of 90% is in line with the 89% average across them. In agriculture, forestry and fishing (3,430 micro businesses in Somerset), seasonal income, grants and farm equipment need careful year-end treatment, so we tie your accounts to bank records and an asset register. In professional, scientific and technical services (2,900 micro businesses in Somerset), 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.
