Subcontractor’s allowable expenses guide

Posted on by Jane Fretwell

As a CIS subcontractor you are classed by HMRC as being self-employed. This means that you can offset business expenses incurred against your total profits when working out your tax.  To qualify, all expenses incurred must be wholly and exclusively for the purposes of your trade. These will be deducted from your gross income.

Common examples of allowable expenses would be:

  • Motor expenses – Where a mileage log has been maintained
  • Telephone – Mobile and use of a home phone
  • Internet – Business element only
  • Small tools – where there are replacements or repairs
  • Use of home as office – can be claimed at £4 per week
  • Rent and rates – where a property is required for the trade
  • Light and heat – on a business property
  • Travel and subsistence – where you are required to work away from home
  • Printing, postage and stationery
  • Accountancy Fees
  • Insurance – such as professional indemnity insurance
  • Subscriptions – to a professional body associated with the trade
  • Advertising and promotion
  • Bank charges and interest

You can also claim capital allowances on any items of plant or machinery that you may need to purchase.

Completing your self-assessment tax return

As a self-employed person, it is a legal requirement to complete a tax return each year. The return must include all of the details of your self-employment plus any other sources of income.
