Answers to the questions we’re asked most often about our services and how we work.
What types of businesses does N-SAS work with?
N-SAS works with businesses of all sizes across the UK — from sole traders and owner-managed SMEs to larger corporates. We have particular expertise in property, technology, professional services, and financial services sectors. We tailor our approach to each client’s specific needs and stage of growth.

How does the initial consultation work?
Your first consultation with N-SAS is completely free and without obligation. It typically lasts 30–60 minutes and can be conducted by phone, video call, or in person. We’ll discuss your business, your current financial situation, and your goals — and give you an honest view of how we can help.
How are your fees structured?
We offer transparent, fixed-fee and retainer-based pricing for most services so you always know what to expect. For project work such as M&A advisory or complex tax restructuring, fees are agreed upfront before work commences. We never surprise our clients with unexpected bills.
Can N-SAS help with HMRC investigations or disputes?
Absolutely. Our experienced tax investigation team handles HMRC enquiries, disputes, and compliance checks. We represent clients throughout the process, from initial correspondence through to tribunal if necessary. Acting early is key — contact us as soon as you receive any HMRC communication.
Does N-SAS offer ongoing support or one-off engagements?
