"How do I submit the "CIS monthly"?"
The "CIS monthly" has to reach HMRC by the 19th of every month.
To submit a pay batch's "CIS monthly":
- First, select the pay batch on:
Menu > Pay batches - Then on the To-do tab, click the upcoming: "CIS monthly"
- Check the details are correct.
- In some cases, you'll be submitting a "nil return", if there hasn't been any CIS payments in the month.
- When you're ready, click: File with HMRC
- It usually takes 15 to 20 seconds for HMRC to finish processing your CIS monthly.
- While you're waiting for HMRC to respond, you can review the notes about "Payment", "Monthly filing dates", and more.
- And finally, you'll see a check on your To-do list to show it's been sent, and that HMRC's confirmed receipt. If you want to see more details, click the check.

Keep in mind that:
- Sometimes you go to a pay batch and there's no mention of "CIS monthly" in the "To-do" tab. If so, it means that the pay batch doesn't have any CIS subcontractors.
- You only have to submit a pay batch's "CIS monthly" if the pay batch has CIS subcontractors.
- Also keep in mind that you may sometimes need to submit a: "nil return"
- A "nil return" is required for any month where the pay batch does have CIS subcontractors, but didn't pay any CIS payments.
Sometimes, you may find you've made additional CIS payments for the tax month, even after you've submitted your: "CIS monthly"
Any additional CIS payments still need to be submitted to HMRC. This is done through an amendment submission of your: "CIS monthly"
To make changes, or send an amendment submission of a pay batch's "CIS monthly":
- First, select the pay batch on:
Menu > Pay batches - Then on the To-do tab, find the upcoming: "CIS monthly"
- Next, hover your mouse over the row and click the "Redo" link.
- The "CIS monthly" now loads with your up-to-date CIS payments for the month.
- You'll see each of your CIS subcontractors that you've made a CIS payment to, listed on one-row each.
- When you're ready, click: File with HMRC
- Like before, it usually takes 15 to 20 seconds for HMRC to finish processing your CIS monthly.
- And finally, as usual, you'll see a check on your To-do list to show it's been sent, and that HMRC's confirmed receipt.

Also remember that:
- Changes or amendment submissions of the "CIS monthly" can be made at any time up until nine months after the end of the tax month.
- This still means that you have to submit something by the 19th of every month, even if it's a: "nil return"
- But you can later resubmit further CIS amendments, even months afterwards.
- Whenever you resubmit the "CIS monthly" with changes, HMRC only stores the latest submitted filing for that tax month.
And that's it! That's all you need to do to resubmit your "CIS monthly"!
