If your year-end close keeps slipping and the tax provision is where it stalls, you are not alone — and the cause is almost always the same. The provision is treated as a year-end task rather than a year-round discipline, and by the time anyone looks at it, there is no time to resolve what it throws up. This guide explains exactly why the provision delays the close, what the delay costs, and how the groups that close on time avoid it.
📌 A typical stalled close
The situation: A growing group targets audit sign-off six weeks after its 31 December year end. Five weeks in, everything is ready except the tax provision. The finance team has drafted a number, but the deferred tax schedule was rebuilt from scratch that week, the reconciliation from accounting profit to tax charge doesn't yet exist, and a judgement on whether to recognise a deferred tax asset on prior-year losses is still open.
What happens: The auditor's first review generates eight queries. Each takes days to answer because the workings weren't built to anticipate them. The loss-recognition judgement bounces back and forth for a week. Sign-off slips from six weeks to ten — past the covenant reporting date, forcing an awkward call to the lender.
What would have prevented it: a deferred tax schedule maintained through the year, the reconciliation built as the numbers firmed up, and the loss judgement resolved and evidenced in November — not litigated in the final week.
Why the provision is where the close stalls
The tax provision sits at the end of the close process and depends on almost everything before it — the final numbers, the fixed asset movements, the provisions, the group position. So it is the last thing prepared, at the point when there is least time left. And it is the one part of the accounts that requires specialist judgement most finance teams don't have in-house. That combination — last in the queue, hardest to do, no specialist to do it — is why it becomes the bottleneck.
Four specific things turn it from a task into a delay:
- Stale data and lost context. By year-end, the people who understood the transactions may have moved on, and the underlying data is months old. Reconstructing what happened takes time the close doesn't have.
- Nobody owns it. The accountant assumes the auditor will sort it; the auditor is not permitted to prepare it; and internally there is no one with the specialist knowledge to take charge. It falls into the gap between compliance and audit, and drifts.
- The reconciliation isn't built. When the reconciliation from accounting profit to tax charge doesn't exist, every auditor query becomes a fresh investigation rather than a quick answer — and the queries pile up.
- Deferred tax judgements left to the deadline. The hardest calls — whether to recognise a deferred tax asset on losses, how to treat an uncertain position — are exactly the ones that need time and evidence. Made under deadline pressure, they either get rushed (and challenged) or stall the whole file while they're resolved.
What the delay actually costs
A slipping close is not just an inconvenience. It has real downstream cost:
Missed filing and reporting deadlines. A late provision delays the accounts, which delays filing, covenant reporting and investor updates — each with its own consequences.
A stalled or fraught audit. When the provision arrives late and unprepared, the tax section of the audit becomes a back-and-forth that can run for weeks, holding up sign-off for the whole set of accounts.
Senior time consumed at the worst moment. The delay pulls the finance director and the wider team into firefighting exactly when they are most stretched — at year-end — instead of the provision being a routine, prepared deliverable.
It repeats. A provision that delayed this year-end, left unfixed, delays the next one too — often worse, because the errors carry forward. For the full picture of what getting it wrong costs, see our guide to getting the provision right.
How the groups that close on time do it
The fix is not to work harder at year-end. It is to stop treating the provision as a year-end event. The groups that close on time do a few things consistently:
- They maintain the deferred tax schedule through the year rather than reconstructing it at year-end — so at the close it needs updating, not building from scratch.
- They resolve the judgement calls early. Loss recognition, uncertain positions — settled before deadline pressure, with evidence documented at the time.
- They build the reconciliation as they go, so it's ready for the auditor rather than assembled in a panic.
- They give the provision an owner — someone with the specialist knowledge to take charge of it as a defined responsibility, not an afterthought.
For a business without an in-house tax team, that ownership is what an Outsourced Head of Tax provides: the provision maintained through the year, the judgements made and evidenced early, the auditors handled, and the close no longer held hostage to the one part of the accounts nobody internally could take charge of. It is often the engagement that begins a longer relationship — the year-end pain is acute enough to prompt action, and once the provision is under control, the same judgement proves valuable across everything else.
Frequently asked questions
Why does the tax provision delay year-end?
Because it sits last in the close, depends on everything before it, and requires specialist judgement most finance teams lack in-house — so it arrives late, unprepared, and generates auditor queries that take time to resolve.
Can the auditor just prepare the provision to speed things up?
No. Auditors are not permitted to prepare the provision they audit — that would compromise their independence. They examine what you present, which is why the quality of what you hand them determines how long the audit takes.
How far ahead should the provision be prepared?
The deferred tax schedule and reconciliation should be maintained through the year, and the key judgements resolved before year-end. At the close, the provision should need updating and finalising, not building from scratch.
We don't have a tax specialist — what are our options?
An Outsourced Head of Tax can own the provision on a retained basis, maintaining it through the year and handling the auditors, giving a growing group senior tax judgement without a full-time hire.
