CT600 filing service for Selkirk businesses: local facts
Selkirk is in the Scottish Borders council area, in Scotland. ONS figures for 2026 count 5,000 VAT- or PAYE-registered businesses in Scottish Borders, and 4,490 of them (90%) employ fewer than ten people. Many are small enough to use the micro-entity regime.
The largest groups of micro businesses in Scottish Borders are agriculture, forestry and fishing (1,130), construction (630) and wholesale and retail (570). For agriculture, forestry and fishing companies in Selkirk, seasonal income, grants and farm equipment need careful year-end treatment, so we tie your accounts to bank records and an asset register. That puts agriculture, forestry and fishing at 25% of the local micro-business base.
Scottish Borders ranks 795 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 construction (630 micro businesses in Scottish Borders), 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 (570 micro businesses in Scottish Borders), 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.
Scottish companies are registered with Companies House in the same way as English ones and the filing deadlines are identical. Scottish income tax bands apply to salary, but dividends and Corporation Tax follow UK rules.

Questions from Selkirk directors
Do I need a CT600 if the company made a loss?
Yes, if HMRC has issued a notice to deliver a return. Filing also lets you carry the loss forward against future profits.
What happens if the CT600 is late?
An automatic £100 penalty applies if it is up to three months late, a further £100 after that, and tax-geared penalties follow if it is six months late.
How many micro businesses are there in Scottish Borders?
The 2026 ONS UK Business Counts show 4,490 micro businesses (fewer than ten employees) among 5,000 VAT- and PAYE-registered businesses in Scottish Borders.

No. Companies House and HMRC filing is entirely online, so we work with you remotely. We are based in Morden, south London, and work with limited companies across the UK, including those in Galashiels, Hawick, Peebles and Selkirk.
