What taxes will I pay as self-employed?

Income Tax: Based on your taxable profits after deducting allowable expenses.

CIS tax refers to the Construction Industry Scheme, which requires contractors to deduct money from a subcontractor’s payments and pass it to HMRC. These deductions count as advance payments towards the subcontractor’s tax and National Insurance. If you are working under CIS, it is important to keep accurate records of your deductions to claim them back in your self-assessment tax return.

How can I get a tax repayment?

To claim a tax repayment:

File your self-assessment tax return accurately.
Include any CIS deductions and other overpaid taxes.
HMRC will calculate the amount owed to you and issue a repayment. Ensure that all your records and claims are accurate to avoid delays.
