Our dedicated team works alongside your organisation to deliver expert guidance and practical strategies, helping you optimise tax efficiency and mitigate risk.
Why Choose an Outsourced Tax Partner?
Partnering with Jerroms Miller means gaining access to award-winning industry specialists who understand the intricacies of tax legislation. We provide tailored services that align with your business needs, offering flexibility, efficiency, and peace of mind.
From routine compliance work to strategic tax planning, we handle the technical details so you can focus on growing your business.
Our Packages
Our retainer packages are designed to give you priority access to senior tax expertise, proactive commercial advice, and long-term strategic support, helping you make confident decisions, faster.
Importantly, day-to-day enquiries that naturally lead to project work are not charged separately. We see these conversations as part of building a strong advisory relationship, not an additional cost.
As you move from Bronze to Gold, you gain increasingly proactive support, greater cost efficiency, and additional resources designed to strengthen your client offering and upskill your team.
Any unused hours can be carried forward to the next month.
Non-Compete Assurance
To protect the integrity of our advice and your commercial position, our retainer relationships include a clear non-compete framework. This means we prioritise your relationship with the client and we work with you to deliver the best outcome.

Why Choose Us
An outsourced tax partner is where your firm can get senior tax expertise without the cost of an in-house tax partner. You can get specialist tax advisers on complex work as and when you need them, either as a flexible pay-as-you-go basis or a monthly retainer package.
A traditional tax consultancy usually works directly with the end business. We work behind you, supporting your firm and your clients, so you can offer corporate tax advisory work when and how you may need. See how we support accountancy firms, lawyers and solicitors and corporate finance teams.
We work in the way that best suits your firm. In most cases, we work through you, allowing you to remain the primary adviser to your client while we provide specialist tax support behind the scenes. Where appropriate, we can also join client meetings alongside you, acting as an extension of your team to deliver expert tax advice.
Reconstructions and demergers, shareholder exits, management buyouts, employee share schemes, SEIS and EIS fundraising, and succession planning, alongside corporate tax advisory and compliance reviews.
Both. Our pay-as-you-go option starts from 30-minute sessions for occasional work, and our Silver and Gold retainers suit firms that need regular support. See our packages.
You will be working with a dedicated, named specialist who coordinates any wider input, so you get a consistent point of contact rather than a different person each time. You can meet the team here.
