If you need to contact your contractor and ask for the records they hold for you, then here is a sample message that you can send them:
Please provide me with my 2017/18 Statement of Earnings that includes:
This information is required in order for me to complete my self-assessment tax return.
- total income
- income liable to deduction
- and tax deducted totals
These can be sent to me or forwarded directly to email@example.com
If they are not able to provide you with your records, then you may be able to contact the CIS Helpline at HMRC and ask them to provide you with a copy of the information they hold for you.
If all else fails, we can submit an appeal for this information on your behalf, although it may take 6-8 weeks for the information to arrive.
