Ireland version
How it works
Calculate a mileage-rate worksheet only after the applicable rate, eligible journeys and reimbursement treatment have been verified.
This is the Ireland planning view, with monetary inputs and outputs in EUR. A currency label does not establish that a tax rate, construction price, coverage rule or legal limit has been verified locally. The inputs and limitations below describe the actual scope.

Formula
modeled claim = maximum(0, eligible business distance × confirmed applicable rate − required reimbursement offset).
Calculations retain numeric precision internally. Displayed values are rounded for readability. Quantities that must be purchased as whole units are rounded up only where the formula explicitly requires it.
Read the inputs before calculating
- Confirmed eligible business distance: Enter the quantity described by the label. The measurement selector converts this physical quantity; it does not change the underlying scenario.
- Confirmed applicable allowance/deduction rate per distance unit: Enter the quantity described by the label. This is a price per displayed unit, so the price converts inversely to the physical quantity.
- Reimbursements that must offset this claim: Enter the quantity described by the label.
- Illustrative applicable marginal tax rate: Enter the quantity described by the label.
Reproducible worked example
The following is a fictional arithmetic example, not a local quote, a verified claimant or a market forecast. Its values are included so the formula can be checked. The form does not automatically confirm any verification checkbox.
0.50 per displayed distance unit is a fictional rate, not a statutory allowance.
| Input | Example value |
|---|---|
| Confirmed eligible business distance (km) | 10,000 |
| Confirmed applicable allowance/deduction rate per distance unit (/km) | 0.5 |
| Reimbursements that must offset this claim | 0 |
| Illustrative applicable marginal tax rate | 25 |
| Output | Calculated result |
|---|---|
| Distance multiplied by confirmed rate | EUR 5,000 |
| Modeled claim after entered reimbursement offset | EUR 5,000 |
| Illustrative tax effect, not a refund | EUR 1,250 |
Interpreting a changed assumption
Start with one complete scenario and change only one input when diagnosing a difference. Recheck units, the period of every rate, whether an amount is recurring or one-off, and whether a cost is already included elsewhere. A larger calculated benefit is not evidence that an assumption is more likely to occur.
Limitations
- Prices, consumption and contract terms are entered scenarios. This is not a retail quote, tax eligibility determination or vehicle safety certification.
- Ordinary commuting is not assumed eligible. UK banded mileage, Irish civil-service reimbursement bands and US deduction eligibility require the actual applicable rule; split rate bands rather than use an invented national flat rate. A deduction is not a cash reimbursement.
Frequently asked questions
What does this Business Mileage Deduction result represent?
Calculate a mileage-rate worksheet only after the applicable rate, eligible journeys and reimbursement treatment have been verified. It applies the displayed formula to your inputs; it does not infer omitted facts.
Are the starting amounts verified Ireland prices or legal rules?
No. Numeric defaults are illustrative unless an input or dated reference explicitly identifies a researched component. Currency is EUR; local quotes, eligibility and unsupported rules must be entered and verified separately.
What must I check before relying on the result?
Prices, consumption and contract terms are entered scenarios. This is not a retail quote, tax eligibility determination or vehicle safety certification.
Can I compare or share different assumptions?
Change one assumption at a time and use the browser-local project or share controls. A shared URL contains the encoded input values; do not include information you do not wish to disclose.
