The layout of the P45 reports can be customised. To customise any of the reports, click the Edit button. See Report Editing for information on how to edit reports. If you do customise a report, the customised version is saved in a text file outside of KwikPay, so you can exchange custom reports with other Kwikpay users.
If you want to run a custom version of a report created outside of your copy of KwikPay, you will need to link that report to KwikPay so that it uses the custom version of the report instead of KwikPay's built-in version. You can do that by clicking the ... button. That will open a file open window where you can select the file name of the custom report.
Both the P45 Report and P45 Summary Report is structured as a main report listing the basic payee details and year to date totals. Note that the P45 report prints information on the HMRC pre-printed P45 laser single sheet stationery, so any changes could upset the alignment of printout on the form.
