In a recent survey of our clients, the most common factor that our contractors enjoyed most about our service was how efficient it was, and how proactive their accountant was.

The purpose of Nasa’s IR35 Guide is to help you understand more about IR35 and to find out how it affects contractors working through their own LTD Company


The guide includes information on the history of the legislation and outlines why it is so important to gain professional assistance in determining whether or not your contracts fall, as HMRC would say ‘inside’ or ‘outside’ of IR35.  It should be noted however that this information should not be relied upon as a tool that solely determines your IR35 status.  It is strongly recommended that you seek a professional IR35 review of each of your contracts along with the true working relationship you have with each client before attempting to declare your IR35 status.


Pricing Structures


We understand that you want an Accountant which is upfront, honest and transparent about Accountancy fees - so we don't hide them.

Many Accountants may ask you to contact them to find out a cost, and then push you with a 'hard-sell' approach.

We're confident in the services we offer, and never push anyone to sign up. Although having your own LTD company isn't a daunting thing, we know it's not always an on-the-spot decision.

We've put all of our pricing and service offerings in one place so you don't have to hunt all over to find out what you need to know:
