Salt.
🇬🇧 White-label for UK firms

White-label capacity for UK accounting firms.

Bookkeeping and MTD-ready VAT preparation for your UK clients, built inside your own Xero or practice-management environment. Your firm keeps the HMRC agent authorisation and the submission.

What your clients are dealing with

A UK client under Making Tax Digital has to produce a VAT return from software carrying an unbroken digital link — no spreadsheet copy-paste into the return — every quarter, alongside CT600 and Companies House deadlines that don't move for a backlog.

Making Tax Digital means the VAT return must come out of MTD-compatible software with an unbroken digital link — no spreadsheet copy-paste into the return.

How Salt slots in

Firms use us for the production layer: bookkeeping, quarterly VAT preparation under MTD, and the accounts and CT600 workpapers assembled ready for review. We work inside your Xero or practice-management environment under your client codes, and we are never client-facing.

What stays with your registered agent

Your firm keeps the HMRC agent authorisation and makes the submission. We prepare MTD-compliant, reconciled files to your standard; we never submit under our own agent code.
