You're doing it right, @MiguelLuis,

We record the money received from the claim as income in QuickBooks Online. Then, the VAT code to use would be NO VAT since this is classified as a refund from HMRC after processing your wage expenses. Let me outline the steps for you.

To add the income account:

1. From the Accounting menu then pick Chart of Accounts.
2. Use the New button.
3. Choose Income from the Account Type ▼ drop-down.
4. Pick a Detail Type from the list.
5. Fill in the Name then Save and close.

To deposit the claim:

1. Tap the + New button, and select Bank Deposit.
2. Enter the account where the claim is to be deposited in the Account field.
3. Update the Date field.
4. Add the income account in the Account column.
5. Enter HMRC in the Received From column to indicate where the fund came from.
6. Add the Amount, then press Save and close when done.
