Preparing for a client's year-end audit request on Italian payroll

A client’s auditor sends a request list for the Italian entity. It lands on your desk in the busiest weeks of the year. The auditor wants evidence, not explanations. This article covers what to produce and how fast.

The scenario  

Your platform employs people in Italy on behalf of a foreign client. The client’s group auditors are closing the year. They ask for proof that Italian payroll, withholding and social contributions are correct and filed. The request usually comes through the client’s finance lead, who is not an Italian payroll expert and needs answers they can forward unchanged.

The partnership manager owns the relationship. The operations manager owns the evidence. Payroll owns the numbers. The audit goes well when those three agree on who sends what before the first reply goes out.

Reply fast, deliver in stages  

Send a short acknowledgment the same day. Confirm that you received the list, name one contact, and say which items you can deliver immediately and which need preparation. Do not wait until everything is ready to say anything.

Then deliver in stages. Auditors prefer a steady flow they can start testing over a late complete package. Put the items that exist as ready documents first. Put the items that need reconciliation last.

Stage one: documents that already exist  

These should be retrievable without new work:

• Employment contracts and any amendments for each employee in scope.
• The national collective agreement applied to each role, with the level and the date it was assigned.
• Payslips for the audit period.
• The payroll register for each period.
• The Certificazione Unica issued to each employee. Per a secondary source, the deadline for employee CUs in 2026 was 2026-03-16. Send the filing receipt together with the document, so the auditor sees both that it was issued and that it was filed on time.

If any of these cannot be pulled quickly, that is a process gap. Note it and fix it after the audit.

Stage two: payments and filings  

This is where auditors spend their time. They want to see that what was withheld and accrued was actually paid and reported.

• Proof of payment of withholding tax and social contributions, matched to the payroll periods they cover.
• Filing receipts for the periodic contribution declarations.
• The status of the annual withholding-agent declaration, the Modello 770. Per a secondary source, the deadline falls on 2026-10-31. That date is a Saturday, so the due date moves to 2026-11-02. If the audit request arrives close to that date, say clearly whether the filing is done, in preparation or scheduled. A plain status line with a date is better than silence.

These dates come from a secondary source. Check them against the official calendar before you quote them to a client in writing.

Stage three: reconciliations  

This is the part that takes preparation. Auditors compare payroll to the general ledger. They want to see that gross pay, employer contributions, withholdings and net pay in your records tie to the amounts the client booked.

Produce a reconciliation by period with these columns:

• Gross pay per payroll register.
• Employer contributions accrued.
• Withholdings accrued.
• Net pay disbursed.
• Amount invoiced to the client.
• Differences, each with a one-line reason.

Unexplained differences are what cause follow-up questions. Explain every one, even the small ones. A rounding note costs you a sentence. A missing explanation costs you a week.

Stage four: leave and variable pay  

Expect questions on accrued leave, end-of-service entitlements, bonuses and benefits. Provide the balance per employee at period end, the rule used to calculate it, and the source document. These are liabilities on the client’s balance sheet, so the auditor will test them.

How to keep the answers usable  

Auditors forward your files to colleagues in other countries. Make each file stand alone.

• Name files by employee reference, period and document type. Never use personal data in file names.
• Add a cover note to each package that says what it contains, the period, and the source system.
• Write in plain English. Give the Italian term once, with its meaning, then use it consistently.
• Keep one index that lists every request item, its status and where the evidence sits.

Protect personal data. Share only what the request requires, through the secure channel the client has agreed to, and log what was sent and when.

What good looks like  

The best response needs very little of your time during the audit itself. The documents are already organized by employee and period. Filing receipts are stored with the filings. Reconciliations are produced as part of each close, not rebuilt on request.

If you must assemble all of this by hand each year, the cost shows up as delay and as exposure. Build the evidence trail into the monthly cycle and an audit request becomes a retrieval task.

Before the next request  

Run a dry run. Take one employee and one period, and try to produce the full evidence set, from contract to filing receipt to ledger tie-out. Time it. Whatever slows you down is what will slow you down in a real audit.

Partnership teams that want to align on how this evidence is exchanged with their platform can request the data-exchange specification.
