Why oil and gas contractors choose us
The problem with generalist accountants
Generalist accountants don’t know the nuances of your work, and that can be costly.
-
You might miss valuable tax deductions
-
You could overpay thousands in tax on salaries or dividends
-
The worldwide subsistence allowance is often not known to generalist accountants
-
IR35 or VAT mistakes can lead to big penalties
We understand your industry. That’s why our clients trust us to deliver personal, specialised support, without the “pile-them-high” factory model. Our work is instead delivered by a Chartered Accountant.
What we can help with
We don’t just “do your accounts” – we focus on strategic planning, identify smart tax deductions, ensure full compliance, and draw on our international experience to create a tailored plan that helps you keep what you earn.
