How to Set a Materiality Threshold for Prepayments
Guidance on setting the right materiality threshold for your prepaid expense policy, so you track what matters and skip what does not.
Not every advance payment needs to be tracked as a prepaid asset. A £50 magazine subscription paid annually does not warrant a 12-month amortization schedule. A £50,000 insurance policy absolutely does. The materiality threshold is the line between the two — and getting it right saves your team significant time while keeping your financials accurate.
What Is a Materiality Threshold?
A materiality threshold for prepayments is the minimum amount above which a payment must be recorded as a prepaid asset and amortized over the benefit period. Below this threshold, the payment can be expensed immediately in the period it is paid. The threshold is set by the company as part of its accounting policy.
How to Determine the Right Level
- Consider your total revenue and balance sheet size — a £1,000 threshold is appropriate for a £5M revenue company but too low for a £100M company
- Look at your audit materiality — your threshold should be well below the overall audit materiality level
- Consider the volume — if setting the threshold at £500 means tracking 200 items, £1,000 or £2,000 may be more practical
- Benchmark against industry practice — most SMBs use a threshold between £500 and £5,000
- Factor in cumulative effect — ten £400 items that you skip individually might add up to a material total
Documenting the Threshold
Your prepaid expense policy should clearly state the threshold, the rationale for choosing it, and the process for reviewing it periodically. Include examples of what falls above and below the line. This makes the policy actionable for your team and defensible with your auditors.
Review your materiality threshold annually. As your business grows, the threshold should increase. As your finance team grows, you may be able to handle a lower threshold.
Edge Cases
Some items fall just below the threshold but recur every month across many departments. In aggregate, they may be material even if individually they are not. Your policy should address this — either by tracking the aggregate or by applying a separate rule for recurring items.
