Why we work with Derry businesses
Derry businesses face a distinct mix of challenges: a strong reliance on tech and manufacturing alongside a large public sector and higher education base. We work with limited company directors, contractors, and small business owners across the City Centre, Waterside, and Bogside, offering remote-first support with in-person meetings on request. Local firms get the confidence they need on corporation tax, VAT, and R&D credits, particularly for the city's growing software and engineering sectors.
The Derry business scene
Derry's economy is unusually balanced for a city of 85,000. Allstate NI's Derry office employs over 1,000 people in software development and business services, while Seagate Technology runs a major manufacturing plant in the Waterside area. Ulster University's Magee campus drives a steady pipeline of spin-outs and contractors in edtech and healthtech. Altnagelvin Hospital is the largest public sector employer in the North West, creating demand for payroll and VAT services among healthcare contractors. Manufacturing remains significant, with Du Pont operating a specialist materials facility near the Creggan estate. The city centre has seen a rise in independent retail and hospitality businesses, many of which need straightforward bookkeeping and VAT support. The Bogside and Creggan areas are home to numerous community enterprises and social enterprises that require tailored accounting for grant-funded income.

How Derry’s economic mix shapes our service emphasis
Derry's sector mix shapes our service emphasis in three clear ways. First, the concentration of tech and software businesses around Allstate NI and Magee means R&D claims are a regular requirement. A Derry software developer automating data processing for the health sector might claim £12,000 in R&D credits against server costs and developer time. Second, Seagate Technology and Du Pont anchor a manufacturing base where capital allowances on plant and machinery, plus patent box relief, are common priorities. A 20-employee precision engineering firm in the Waterside could reduce its corporation tax bill by £8,500 through capital allowances on new CNC equipment. Third, the large public sector and healthcare presence at Altnagelvin Hospital creates demand for payroll and IR35 compliance among locum doctors, nurses, and allied health contractors. We also see many higher education contractors from Magee needing help with trading through a limited company, VAT registration, and quarterly filing. We advise on cross-border issues for clients working in Buncrana or Strabane while remaining UK tax compliant.

Derry worked example
Worked example: £15,585 net R&D credit on £103,900 of spend
8-employee software developer
Take a Derry city centre software developer with two full time developers and three contractors, building an AI driven diagnostic tool for a local hospital trust. Software work is often left out of R&D claims on the assumption that relief is for physical products. It is not: algorithm design and data processing that resolve genuine technical uncertainty qualify, and the evidence sits in project records, sprint notes and test results. Suppose those records support £103,900 of qualifying expenditure. Under the merged R&D expenditure credit scheme at 20 per cent that is a £20,780 gross credit, worth £15,585 net after the corporation tax charge on the credit at the 25 per cent main rate. If part of the output is exempt, a partial exemption method may also recover input tax currently blocked.
Illustrative example. It is not a record of a client engagement and the figures are worked through to show how the rules apply, not taken from a real return.
