You can apply for two tax credits, Child Tax Credit and Working Tax Credit .
Child Tax Credit is a payment for people with children, whether they are in or out of work. It is paid by HM Revenue and Customs (HMRC). You can get Child Tax Credit if your income is low enough and you are responsible for at least one child. You will get money from Child Tax Credit for each child. You do not need to have a very low income to get some help from Child Tax Credit, so most people with children get the credit.

If you are working, you may still be able to get benefits or tax credits if you are on a low income. It does not matter whether you are working for someone else or self-employed. The benefits you can get depend on your circumstances, your earnings and other money you have coming in, and on how many hours you work each week. There are different benefits for people who work less than 16 hours a week and for people who work 16 hours or more.
This information is mainly for people who work at least 16 hours a week. There is also information about help if you work less than 16 hours, and if you get certain benefits and then start work or increase your hours or wages.
