Follow the process outlined here if you have outstanding invoices from your previous system, and you want to include them on CIS reports and returns produced from Sage Accounting. Your CIS reports and returns will not be accurate unless you follow this process.
We may record your CIS in different ledger accounts to the system you have come from, and this will affect the way you enter your opening balances
As all outstanding invoices with CIS must be re-entered in Accounting, you'll need to follow this process to enter your opening balances correctly.
You may have some CIS invoices that are already paid from your old system as well as some unpaid ones for the same period. This means you'll have a mixture of invoices from both systems for the same reporting period. When this happens:
Enter opening balances for CIS on sales
Enter the current outstanding balance for each customer contact who is a contractor. You can enter this as a single overall total or enter multiple outstanding balances for the same customer.
For your outstanding CIS invoices, the opening balance will be the total invoice values less the amount of CIS withheld.
TIP:
In our example, we have an outstanding invoice for a contractor where we charged £100 labour with a CIS deduction rate of 30%. The outstanding amount will be for £90. (£100 Labour + £20 VAT less the £30 CIS)
In the example below, we've added an opening balance for a CIS contractor for £90.

If you're entering more than one opening balance, repeat for each one.
You can easily adjust the opening balances if you make a mistake. Just select the opening balance and make the required changes.
Next enter the balance of your CIS ledger accounts. This is usually taken from the final trial balance used in your old system.
When you activated CIS, we set up the additional CIS ledger accounts of CIS Tax Withheld and CIS Labour for you. We recommend that you use the CIS Tax Withheld ledger account we have created and enter your opening balance against this account.
For your CIS Labour Expense or CIS Materials, you can use the ledger accounts we have set up for you and enter opening balances against these accounts. You can also use your existing ledger accounts, make sure you set them as CIS ledger accounts before you start.
For CIS, you will have an opening balance for the Trade Debtors, CIS Withheld, VAT, as well as the ledger accounts you used for labour and materials.
In our example shown below, as we only have one outstanding CIS invoice, we've added the following opening balances.
| Ledger Account | Debit | Credit |
|---|---|---|
| 1132 CIS Withheld | 30 | |
| 4911 CIS Labour | 100 | |
| 2200 VAT on Sales | 20 |
In our example, the opening balances for our single outstanding balance will have values for the Trade Debtors, CIS Tax Asset Withheld, CIS Labour and VAT.

You can easily adjust the opening balances if you make a mistake. Just open the opening balance and make the required changes to the ledger account or amount.
To make sure your outstanding CIS invoices are reported correctly on CIS reports and returns, you must re-enter them in Sage Accounting.
Before you can do this, reverse your outstanding balance for each CIS supplier with a credit note.
Make sure that you use the ledger account for CIS Labour Expense, so the CIS is deducted automatically.
Enter the following information:
| Date | Enter your start date in Accounting. |
| Ledger account | Choose the ledger account for CIS Labour. If you also charged for materials, enter this on a second line using the CIS Materials ledger account. This is to ensure the CIS is deducted from the credit note and the balance of the ledger accounts is reduced correctly. |
| Amount | Enter the total net value of all outstanding CIS invoices. In our example, this £100. |
| VAT | If you're on the Standard VAT scheme, select the VAT rate used for the original invoice. This will be added to your VAT Return but then reversed when you re-create your CIS invoices. |
In our example shown below, as we only had one outstanding invoice, we've just entered a single credit note. Here you can see that the CIS has been deducted.

If we check our trial balance, we'll now see our CIS opening balances reversed. In our example, we only entered opening balances for our single CIS invoice, so the trial balance now shows zero.

This is to make sure the credit note is not left outstanding on your customer's account.

Now that everything has been reversed, just re-enter your outstanding CIS invoices. Enter each outstanding invoice individually as you'll need to know when it's been paid and make sure the CIS is reported correctly.
This will:
Enter the following information:
| Date | Enter your start date in Accounting. This should be the same date that you used for the credit note. |
| Ledger account | Choose the ledger account for CIS Labour. If you're also charging for materials, enter this on a second line, using the ledger account you used for the credit note. This is to make sure that CIS is deducted on the invoice and the balance of the correct ledger accounts is updated correctly. |
| Amount | Enter the net value of the outstanding CIS invoice. In our example, as we only have the one invoice, this is £100. |
| VAT | If you're on the Standard VAT scheme, select the VAT rate used for the original invoice. This reverses the VAT recorded on the credit note. |
In our example shown below, the following ledger accounts have been updated
| Ledger Account | Debit | Credit |
|---|---|---|
| Trade Debtors | 90 | |
| 1132 CIS Withheld | 30 | |
| 4911 CIS Labour | 100 | |
| 2200 VAT on Sales | 20 |
The trial balance will now reflect the value of your outstanding invoices and will be reported on your CIS reports and returns.

Enter the current outstanding balance for each supplier who is also a sub-contractor. You can enter this as a single overall total or enter multiple outstanding balances for the same supplier.
You'll need to enter the total amount outstanding, but it's only the total of CIS invoices that we're interested in for the rest of the process.
For your outstanding CIS invoices, the opening balance will be the total invoice values less the CIS deducted.
TIP:
For example, we have an outstanding invoice for a subcontractor where we've been charged £100 labour with a CIS deduction rate of 30%. The outstanding amount will be for £90 (£100 Labour + £20 VAT less the £30 CIS).
In the example below, we've added an opening balance for a CIS subcontractor for £90.

If you're entering more than one opening balance, repeat for each one.
Next enter the balance of your CIS ledger accounts. This is usually taken from the final trial balance used in your old system.
When you activated CIS, we set up additional CIS ledger accounts CIS Tax Liability and CIS Labour Expense for you.
We recommend that you use the ledger accounts we have created and enter your opening balance against this account.
For your CIS Labour Expense or CIS Materials, you can either:
If you want to do this then:
For CIS, you will have an opening balance for the Trade Creditors, CIS Tax Liability, VAT, as well as the ledger accounts you used for CIS Labour Expense and CIS Materials.
If you make a mistake, you can change your opening balances at any time.
In our example shown below, as we only have one outstanding CIS invoice, we've added the following opening balances.
| Ledger Account | Debit | Credit |
|---|---|---|
| 1132 CIS Tax Liability | 30 | |
| 4911 CIS Labour Expense | 100 | |
| 2200 VAT on purchases | 20 |

To make sure your outstanding CIS invoices are reported correctly on CIS reports and returns, you must re-enter them in Sage Accounting.

Enter the following information:
| Date | Enter your start date in Accounting. |
| Ledger account | Choose ledger account for CIS Labour Expense. This is to ensure CIS is deducted from the credit note and the balance of the ledger account is reduced correctly. |
| Amount | Enter the total net value for labour of your outstanding CIS invoices. In our example, this is £100. |
| VAT | If you're on the Standard VAT scheme, select the VAT rate used for the original invoice. This will be added to your VAT Return but then reversed when you re-create your CIS invoices. |
In our example shown below, as we only had one outstanding invoice, we've just entered a single credit note. Here you can see that the CIS has been deducted.

If you check your trial balance, you'll now see your CIS opening balances reversed. In our example, we only entered opening balances for our single CIS invoice, so the trial balance now shows zero.

| Trade Creditors | 90 | |
| 1132 CIS Tax Liability | 30 | |
| 4911 CIS Labour Expense | 100 | |
| 2200 VAT on Purchases | 20 |
The trial balance will now reflect the value of your outstanding invoices and will be reported on your CIS report and returns.
