Honest answers

Working-papers questions, answered.

A one-page summary mapping the workings to the return boxes, per-supplier purchase schedules with VAT per line, a sales schedule, a separate reverse-charge schedule, an adjustments note (rounding, inferences, corrections), and the source documents themselves — attached or embedded, not in a separate archive. The test: any figure traces to its document in under a minute.

At least 6 years from the end of the tax year they relate to — invoices issued and received, the VAT account, and the workings behind each return. Firms with cross-border clients often retain longer, since several EU jurisdictions require 10 years.

Keep the inference visible: the row shows the rate applied, a flag that it was inferred rather than printed, and the source wording from the document preserved alongside. An inspector who can see what the document said and why the rate was chosen has nothing further to ask — it is the silent inference that invites questions.

Yes — the statement is the external check on the file. Payments without documents are missing paperwork; documents without payments deserve a look. Reconciling inside the period workflow, while the trail is warm, is dramatically cheaper than reconstructing it at year end.

The structure matters more than the tool. Excel with per-supplier schedules, embedded sources, and documented adjustments beats software that produces an opaque feed. The practical answer is both: Pileform generates the Excel file with the structure and evidence built in, and posts the confirmed entries to the ledger from the same workings.

The file builds itself.

Pileform outputs per-supplier workbooks with the source embedded and the adjustments shown — working papers as a byproduct. Sign up free, no card.
