Northern Ireland is part of the United Kingdom, but it is not just another regional market. The work has to be clear about UK tax, and about the special VAT rules that can apply when goods move across the Irish border.
TreyBridge Accountants works with owner-managed businesses in Belfast and across Northern Ireland from our office in Hull. We have one office, and it is not in Belfast. Day-to-day work is done online in your accounting software, with video meetings as the normal rhythm and an in-person meeting only where travel can be arranged and is genuinely useful.
Northern Ireland is part of the UK, so UK tax, HMRC filings and Companies House rules apply in a way they do not for a company in the Republic of Ireland. That is one reason a Hull firm that already serves businesses across the UK and Ireland can be a practical fit, provided we are honest about how the relationship works.
Our motto is Navigating Your Numbers. We are known for tax planning, management accounts, helping businesses become more profitable, and getting accounts in order. We work with owners in many sectors, not only digital or technology firms, including businesses heading towards £1 million turnover and beyond.
Official figures show a substantial owner-managed market. As of March 2026, Belfast had 11,485 VAT and/or PAYE enterprises, according to the Office for National Statistics. Around that sit ports and logistics, manufacturing, agri-food, construction, professional and public services, retail, hospitality and a growing technology community.
The distinctive issue for many owners is not only the usual questions of profit, cash, salary and dividends. It is also the border. Goods moving between Northern Ireland and the EU, including the Republic of Ireland, can fall under the Windsor Framework. In that goods regime, a business identified as trading under the framework uses an XI prefix in front of its UK VAT number on paperwork with EU customers or suppliers. Services generally follow ordinary UK VAT rules, not that goods framework. If your Northern Ireland company also has a sister company in the Republic of Ireland, or you sell goods into Great Britain or the EU, the UK VAT position needs to be thought through carefully. We have a dedicated page on UK VAT returns for Irish companies where that is the main need.
The practical model is remote. We are a Xero Gold Partner and also support QuickBooks, Sage and FreeAgent. Dext can keep receipts and bills moving without anyone posting a folder to Hull. Payroll and personal tax can sit with the same team, so director pay and the company's tax plan are not pulled in different directions.
Meetings are by video as standard. You can also come to our office at C4DI, Queen Street, Hull, if you are travelling to Great Britain. We will not describe ourselves as a Belfast firm, and we will not imply that we have a branch in Northern Ireland.
Aaron Gilmore is personally ACCA registered. The firm itself is not an ACCA firm. The firm is supervised by HMRC for anti-money laundering and is registered with Companies House as an Authorised Corporate Service Provider. This is the same remote-first service we provide to clients elsewhere in the UK and Ireland, including London and Manchester.
We get the books onto a reliable cycle, prepare management accounts, plan tax before the year end, and keep filing on time. If the records have slipped, we start there. If you are considering a change of accountant, we will handle the handover with your permission. Where UK VAT, including XI treatment for goods, is part of the picture, we will be clear about what we can do in-house and when specialist customs support is the safer route. We will talk about profit, cash, tax and the decisions in front of you, in plain English.
No. We have one office, in Hull. We work with Belfast and Northern Ireland clients online, with video meetings as standard. We will not present a Belfast address or telephone number as our own.
Yes, for most owner-managed businesses. Northern Ireland is part of the UK, so HMRC and Companies House filings are national, the books can be kept in cloud software, and meetings can be by video. An in-person meeting in Hull can be arranged if you are travelling.
We can help you keep UK VAT returns on time in compatible software, and we can explain the official difference between goods, which may use an XI VAT prefix under the Windsor Framework, and services, which generally follow ordinary UK rules. Some goods movements need specialist customs support, and we will say so if that is the case. If you also have a company in the Republic of Ireland that needs help with UK VAT, see our page on UK VAT returns for Irish companies.
No. Professional services and technology are part of the city's mix, but we also work with trades, manufacturers, agri-food businesses, retailers, hospitality businesses and other owner-managed companies across Northern Ireland.
Yes, in most cases. We are a Xero Gold Partner and also support QuickBooks, Sage and FreeAgent. If your current system is doing its job, we can usually continue with it. If it is not, we will talk through a move before anything is changed.
