Apportioned claimant-paid bills
apportionedBillsBeforeReimbursement = round to cents(allowableBillsActuallyPaid × remoteDays ÷ daysInAssessmentYear)

Where

allowableBillsActuallyPaid

apportionedBillsBeforeReimbursement
Apportioned claimant-paid bills (EUR/year)Source: Calculated output

Money inputs and outputs use EUR. Pay, time, benefits and work-related costs use the units stated beside each input.

2. Worked example

Input assumptions

Apportion €1,200 of claimant-paid allowable bills across 120 eligible remote days.

Calculation and outputs

Example

Apportion €1,200 of claimant-paid allowable bills across 120 eligible remote days.

Estimated Income Tax relief
47.34 currency units
Allowable remote-working cost
118.36 currency units
Specified amount after reimbursement
394.52 currency units
Apportioned claimant-paid bills
394.52 currency units

Apportioned bills, reimbursement, allowable cost and estimated relief remain separate.

Interpretation

Use the result only for supported expenses, workdays and the entered tax rate.

3. Validation and boundary checks

  • The worked example uses the same shared-work-logic engine as the interactive planner.
  • Unsupported eligibility, policy branches and out-of-range assumptions fail closed.
  • Result cards, trace, CSV, PDF and methodology bind to named engine result fields.

4. Assumptions and source classification

  • Costs and remote days meet Revenue eligibility rules.
  • The entered bills are the claimant-paid share after any household split.
  • The highest Income Tax rate is confirmed.

Official dependencies used by this calculator are captured in the Wage101 evidence register and version-acknowledged in this page history. User-entered work and pay assumptions remain separate from those official inputs.

5. Limitations

  • The tool does not decide expense eligibility or claim acceptance.
  • Employer daily allowance, USC, PRSI and full tax return effects are excluded.

This is educational decision support, not personalised tax, legal, financial or career advice. Check how the rules that apply in Ireland treat your work and pay circumstances, and seek qualified advice where appropriate.

6. Update and evidence policy

Registered family-level suites test formula invariants and example reconciliation; the release ledger records that coverage without claiming a separate oracle for every line of public copy. Registered official sources block dependent public workflows when their evidence or version acknowledgement is unavailable or invalid. Work and pay inputs remain user-supplied because they vary by person, job and contract.
