A provision is neither a precautionary reserve nor a means of smoothing results. It is the accounting expression of an obligation that has already arisen at the closing date, whose timing or amount remains uncertain. This definition, which may seem theoretical, settles almost all tax reassessments on the subject: what the tax authorities reject is almost never an excessive provision, but a provision set up for a risk that did not yet exist at the closing date.
The three cumulative conditions
A provision may be recognised only if the following three conditions are all met:
- The entity has an obligation towards a third party at the closing date. This obligation may be legal — a contract, a law, a dispute — or implicit, arising from a consistent practice that creates a legitimate expectation on the part of the third party.
- It is probable or certain that this obligation will result in an outflow of resources, without at least an equivalent consideration expected from that third party.
- The amount can be reliably estimated.
The second condition is the one that rules out the most provision proposals. A future expense that provides a consideration in return — an investment, a marketing campaign, a recruitment — cannot be provisioned, however certain it may be. The outflow of resources must be without any return.
The first eliminates provisions for future risks. A dispute arising after the closing date cannot be provisioned for the closed financial year, even if the event occurs before the accounts are finalised; it may, where relevant, be disclosed in the notes.
Provision, impairment, accrued expense
Three related notions that tax reassessments distinguish carefully.
The provision for risks and charges appears on the liabilities side. It covers an obligation whose timing or amount is uncertain: an employment tribunal dispute, a warranty given to customers, restructuring already under way, site remediation.
Impairment adjusts the value of an asset on the assets side of the balance sheet. It records that a receivable, inventory or security is worth less than its carrying amount. A doubtful receivable is not covered by a provision on the liabilities side but by an impairment, assessed receivable by receivable.
The accrued expense corresponds to an obligation that is certain both in its principle and in its amount, simply not yet invoiced. It does not fall under the provisions regime and does not need to meet its conditions.
Classifying an accrued expense as a provision, or vice versa, is not a neutral choice: provisions appear on a special statement attached to the income tax return, and their deductibility regime is more stringent.
The most common provisions
For litigation. This requires legal action initiated or a claim made before the closing date. Its amount is assessed against the actual risk, not the opposing party's claim. Systematically provisioning the full amount of the claimant's demands is a practice regularly challenged.
For warranties given to customers. This may be based on historical claims statistics, provided the statistics are documented and specific to the company. This is one of the rare cases where a statistical approach is accepted.
For impairment of receivables. This requires an individual assessment. A provision calculated by applying a uniform percentage to all overdue receivables is the textbook case for rejection.
For restructuring. This requires a detailed plan and an announcement creating a legitimate expectation among the persons concerned before the closing date. An intention that has not been formalised is not sufficient.
For pension obligations. Their recognition on the liabilities side is optional in individual financial statements, with provisioning being the preferred method. Their tax deductibility, however, is excluded.
Tax deductibility
A provision that has been properly recognised is not necessarily deductible. Tax rules add their own conditions: the expense must be clearly specified as to its nature and amount, probable and not merely contingent, and must result from events occurring at the closing date. The provision must finally be actually recognised in the accounts and appear on the special statement.
Expressly excluded from the right to deduct, among others, are:
- Provisions for self-insurance, where the company chooses not to take out insurance.
- Provisions covering fines and penalties, which are themselves non-deductible.
- Provisions for pension obligations.
- Provisions calculated on a flat-rate basis, without a case-by-case analysis.
This last point is the most common ground for reassessment. The statistical method is accepted only where it is based on data specific to the company, documented, and applied to a homogeneous population — provisions for warranties being the typical example. These principles form part of the general framework set out in our article on corporate taxation.
Reversal, a symmetrical obligation
A provision must be reversed as soon as the obligation disappears or its amount is revised downward. The reversal constitutes taxable income for the financial year.
Maintaining a provision that has become unjustified is an irregularity just as much as setting it up without justification, and it is easier to detect: an audit compares the provision with the event that gave rise to it. A provision for litigation maintained three years after a settlement was signed is an immediate red flag, and it weighs against the assessment of good faith during a tax audit.
Symmetrically, the provision must be adjusted upward if the risk worsens, without waiting for it to materialise.
Usage scenarios
Employment tribunal dispute ongoing at the closing date. Provision for the risk assessed with legal counsel, documenting the valuation method. Keep the analysis memo: it is what justifies the amount, not the opposing party's claim.
Overdue customer receivables. Assess on a case-by-case basis, taking into account reminders, guarantees and the debtor's situation. Document the reasoning for each impaired receivable.
Year-end closing. Review both existing and new provisions. Omitted reversals are just as costly as unjustified provisions, and are easier to detect. The related discipline falls under bookkeeping.
Frequently asked questions
When can a provision be set up? When an obligation towards a third party exists at the closing date, an outflow of resources without equivalent consideration is probable, and the amount can be reliably estimated. The three conditions are cumulative.
Is a provision always deductible? No. Deductibility adds its own conditions and expressly excludes several categories, including flat-rate provisions, self-insurance provisions and pension obligation provisions.
What is the difference with an impairment? A provision appears on the liabilities side and covers an obligation; an impairment adjusts the value of an item on the assets side. A doubtful receivable is covered by an impairment, assessed individually.
Can a future risk be provisioned? No. The event must be ongoing at the closing date. A dispute arising after the closing date is disclosed in the notes, not provisioned for the closed financial year.
What happens if the risk disappears? The provision must be reversed, which generates taxable income. Keeping it in place is an irregularity, easily detected during an audit.
Is a flat percentage on receivables accepted? No, not for receivables, which require an individual assessment. A statistical approach is accepted only for homogeneous populations and with documented data specific to the company, as is the case for warranty provisions.
Key takeaways
A provision is justified by a fact, not by caution. The fact must exist at the closing date, commit the company towards a third party, and result in an outflow of resources without consideration.
Two habits avoid almost all tax reassessments. Documenting each provision individually, which rules out flat rates and uniform percentages. And reviewing existing provisions every year to reverse those that have become unjustified — an omission that is easier to spot, and more damaging to the assessment of good faith, than the provision itself. The logic is the same as that governing depreciation: the accounting treatment must reflect a demonstrable economic reality, not an intention.
