# How do I submit third party payment files to Cintra for processing?

Similar to paying **HMRC**, the **Pay Third Party** functionality allows you to combine payments, from different payrolls to third parties, into a single payment file and makes a payment run to a third party person or company/organisation. A third party payment can be for union dues or child care etc.

Now that you have created a third party payment file, you can you can use **Cintra** to pay your **HMRC** payments.
