This guide explains how to use the Count.ie vat registration threshold headroom. Compare relevant annual domestic taxable turnover with the ordinary Irish goods/services thresholds. Follow the inputs, method and worked example below, then compare your own scenario.
Guide written .
Open the VAT registration threshold headroom calculatorWhat to prepare
- Gather supplier quotes, invoices, time records and the actual scope of the job or business decision.
- Separate revenue from VAT, direct costs from overheads, and profit from the timing of cash receipts.
- Use the same accounting period and currency for related inputs.
Understand the inputs
The calculation method
Ordinary services threshold €42,500; goods threshold €85,000. Mixed supplies use €85,000 when qualifying goods are at least 90% of turnover; the zero-rated-material manufacturing exception uses €42,500.
Worked example
Illustrative inputs and their result.
Example inputs
- Relevant annual domestic taxable goods turnover, ex-VAT (€)
- 0
- Relevant annual domestic taxable services turnover, ex-VAT (€)
- 40000
- Goods manufactured/produced from zero-rated materials and sold at reduced/standard VAT
- No
Calculated example result
- Threshold
- €42,500.00
- Remaining Headroom
- €2,500.00
- Turnover Excess
- €0.00
How to interpret the result
A profitable estimate can still create a cash shortfall. Read the cost and timing assumptions as well as the headline profit, price or return; the result is a scenario, not a sales forecast.
Keep the scope constant while changing price, volume, supplier cost or time. A lower-sales or higher-cost case helps show whether the decision depends on an optimistic assumption.
Common mistakes to avoid
- Do not confuse markup on cost with margin on selling price.
- Include work that is easy to miss, such as travel, setup, rework and administration, where the model supports it.
- Do not treat tax collected or an unpaid invoice as freely available cash.
Assumptions and sources
Threshold comparison, not a registration decision. Irish-established domestic traders only. Confirm the applicable annual assessment period and turnover definition. Imports/acquisitions, cross-border supplies, exempt activities, non-established traders and EU SME eligibility can create separate obligations.
