What filers said

“It’s wonderful! We have saved so much time in completing our tax returns. It is so easy to use — if there are problems they are worded so that you can understand the problem.”
Questions
What gets filed?
The CIS300 monthly return, and subcontractor tax-treatment verifications.
Do I still log into the Government Gateway?
Not for each return. Gateway Solver keeps the credentials on the PC that files, and sends the return from there.
What if my figures are already in Excel or a payroll system?
Import a CSV or Excel file, or let payroll or an in-house system drive the upload.
HMRC’s supplier list still shows the earlier name, Insite 123, next to Gateway Solver. The list is on GOV.UK. Install notes and the knowledge base are on the product page.
