Contractor Accountants

If you are currently working as a contractor (or are considering working as one), you have the opportunity to take home a greater proportion of your earnings each month. In order to do so, however, it’s important that you make the right choices. If you make the wrong ones, you could end up facing a significant level of paperwork or even fines from HMRC for failure to comply with IR35.

Get it right and you can benefit from taking home a greater percentage of your earnings each month and relax, not having to worry about admin tasks and paperwork.

Focusing on the three principles of trust, care and compliance, ICS is here to help contractors remain compliant, increase their monthly take home income and reduce the stress of paperwork and admin tasks.

Limited Company Service
