What are the four steps in a return's drawer on HMRC Dues?

On the Returns tab each company × tax × period is a row; click it for the drawer. 1 Check runs the pre-submission checks against Xero. 2 File records the filing made in Xero, the payroll app or the accountant's software and stores the return. 3 Pay adds the filed liability to a payment run. 4 Match ties the bank payment Xero recorded to the period, which is what turns the row Paid. An unfiled period's amount is Xero's figure so far, shown grey — an estimate, not a debt. Filter by tax and by To file, Done or All.
