Providing excellent service since 1988


Contractor Specialists

Qdos began in 1988 as a tax consultancy business and has grown in both size and reputation to become one of the leading providers of contractor specific insurance and one of the leading authorities on the IR35 legislation.

Unique Contractor Insurance


Over 50,000 contractors have entrusted Qdos Contractor to insure the risks of their contracting lifestyle. Qdos offers a wide range of business insurances from Professional Indemnity to Legal Expenses Insurance to a variety of trades from IT Contractors to Offshore Rope Access Technicians.

Qdos Contractor introduced tax loss insurance to the contractor market with the revolutionary Tax Liability Cover (TLC35), the first IR35 insurance to insure contractors for the losses if they were eventually caught by the IR35 legislation. This is one of our most popular insurance policies and we continue to find ways to ensure our customers are covered for the risks they face.

Leading Authority on IR35 Since 2000


Since the legislation came in to force in 2000, Qdos Contractor has been at the forefront of defending contractors against the legislation, providing IR35 insurances and contract review services.

We have successfully defended over 1,500 cases, and saved contractors over £35 million in tax.

Our tax advisers are ex-Revenue inspectors themselves and have been fighting the legislation since its implementation.

Over 50 accountants and recruitment agencies trust Qdos' opinion on IR35 status

Our team review over 600 contracts every month for IR35 status


Qdos Contractor led the way for stakeholders regarding the off-payroll working in the public sector changes which came into force April 2017, using their IR35 experience, technology and insurance capabilities to provide a pragmatic solution to recruitment agencies, public sector bodies, and contractors.
