"How do I file the "CIS monthly"?" 

The "CIS monthly" has to reach HMRC by the 19th of every month. 

To file a pay batch's "CIS monthly": 

1. First, select the pay batch on: Menu > Pay batches 
2. Then click: Monthly > CIS monthly 
3. Check the details are correct. 
4. And click: File with HMRC 
5. And then click: Yes ... mark as done 
6. It usually takes HMRC around 15-20 seconds to finish processing the return and send back the result. 
7. And finally, you'll see two checkmarks on your To-do list to show it's been sent, and that HMRC confirmed receipt. If you want to see more details, click either of the checkmarks. 

"How do I re-file the "CIS monthly"?" 

To make amendments to a pay batch's "CIS monthly": 

1. First, hover your mouse over the row and click the "Redo" link. 
2. The "CIS monthly" now loads with the up-to-date info. 
3. You could also check the box for nil returns if needed. 
4. Then click: File with HMRC 
5. And finally, when you re-file the "CIS monthly" with changes, HMRC only stores your last filing. 

And that's it! That's all you need to do to re-file your "CIS monthly"!
