The Official Revenue Formula
Understanding the Core Formula
Revenue’s remote working relief calculation uses the formula: ((A × B) ÷ C – D) × 30%, where each variable represents specific elements of your working arrangement and costs:
-
A = Total allowable utility bills (electricity, heating, broadband)
-
B = Number of days worked from home during the year
-
C = Total days in the year (365 or 366)
-
D = Employer allowance received for remote working
This formula ensures fair apportionment of household utility costs to work-related activities while accounting for employer contributions and preventing double-relief claiming.
Professional calculation services ensure accurate variable identification and optimal formula application that maximises relief within Revenue compliance requirements.
Before calculating your claim, confirm your eligibility through Who Qualifies for Remote Work Tax Relief Ireland 2025.
Formula Component Breakdown
Variable A (Utility Bills): Include all qualifying electricity, heating, and broadband expenses paid during the tax year. This encompasses various utility types and payment arrangements that require comprehensive identification.
Variable B (Working Days): Count actual days spent working from home, excluding weekends, holidays, leave periods, and office working days. Accurate counting significantly impacts final relief amounts.
Variable C (Year Days): Use 365 days for standard years or 366 for leap years. This ensures proper proportional calculation regardless of calendar variations.
Variable D (Employer Allowance): Deduct all employer payments for remote working to prevent double-claiming and ensure compliance with Revenue requirements.
Step-by-Step Calculation Process
Step 1: Gathering Utility Cost Information
Begin by collecting annual utility bills for electricity, heating, and broadband services covering the complete tax year. Include all qualifying expenses regardless of payment method or billing frequency.
Electricity costs should encompass all domestic electricity consumption, including electric heating systems that serve home office spaces during working periods.
Heating expenses include gas, oil, solid fuel, and other heating systems that maintain comfortable working temperatures during remote work hours.
Broadband costs cover high-speed internet connectivity essential for remote working, including reasonable portions of bundled services that include internet connectivity.
Professional expense identification typically uncovers 15-25% more qualifying costs than self-analysis through comprehensive utility categorisation and optimal inclusion procedures.
Step 2: Accurate Working Day Counting
Count every day you performed substantial employment duties from home, including regular scheduled days, additional remote work, and approved home working that substituted for office activities.
Include days when you worked full home schedules, partial home days that met substantial work criteria, and home working due to circumstances like weather or meetings.
Exclude office working days, annual leave, public holidays, sick leave (unless worked from home), and weekend work outside normal employment hours.
Professional day counting methodology often identifies 20-30 additional qualifying days annually through comprehensive day classification and optimal counting procedures.
Step 3: Employer Allowance Documentation
Document all employer payments related to remote working, including daily allowances, reimbursements, and any other payments designed to support home working costs.
Include regular daily allowances, occasional reimbursements, equipment allowances that substitute for relief claiming, and other employer contributions to home working costs.
Calculate total annual employer contributions accurately to ensure proper deduction from relief calculations and compliance with Revenue requirements.
Professional allowance coordination ensures optimal balance between employer payments and employee relief claims for maximum overall tax efficiency.
Step 4: Applying the Mathematical Formula
Insert identified values into Revenue’s formula: ((Utility Bills × Working Days) ÷ 365 – Employer Allowance) × 30%
This calculation determines your “specified amount” eligible for tax relief at your marginal tax rate, creating the foundation for final benefit calculation.
Verify calculation accuracy through cross-checking and validation procedures that prevent common mathematical errors in complex multi-variable formulas.
Professional calculation services ensure mathematical accuracy while optimising formula application for maximum legitimate relief recovery.
Step 5: Tax Benefit Calculation
Apply your marginal tax rate to the specified amount: Standard rate taxpayers (20%) receive €20 benefit per €100 specified amount, while higher rate taxpayers (40%) receive €40 benefit per €100.
The tax benefit calculation determines actual cash refund amounts, demonstrating how tax rate differences significantly impact final relief values for identical circumstances.
Understanding benefit calculation helps set realistic expectations while highlighting opportunities for strategic tax planning that enhances relief outcomes.
Detailed Calculation Examples
Example 1: Full-Time Remote Worker
Michael’s Situation:
-
Annual electricity/heating: €2,000
-
Annual broadband: €600
-
Home working days: 240
-
Employer allowance: €0
-
Tax rate: 40%
Calculation Process:
-
Total utilities: €2,000 + €600 = €2,600
-
Apportionment: (€2,600 × 240) ÷ 365 = €1,709
-
Less employer allowance: €1,709 – €0 = €1,709
-
30% relief rate: €1,709 × 30% = €513
-
Tax benefit: €513 × 40% = €205
Result: Michael receives €205 annual tax relief.
Example 2: Hybrid Worker with Employer Allowance
Sarah’s Situation:
-
Annual utilities: €1,800
-
Home working days: 120
-
Employer allowance: €2.50 per day (€300 total)
-
Tax rate: 20%
Calculation Process:
-
Apportionment: (€1,800 × 120) ÷ 365 = €591
-
Less employer allowance: €591 – €300 = €291
-
30% relief rate: €291 × 30% = €87
-
Tax benefit: €87 × 20% = €17
Result: Sarah receives €17 additional relief plus €300 tax-free employer allowance.
Example 3: Part-Time Remote Worker
Emma’s Situation:
-
Annual utilities: €1,200
-
Home working days: 80
-
Employer allowance: €0
-
Tax rate: 20%
Calculation Process:
-
Apportionment: (€1,200 × 80) ÷ 365 = €263
-
30% relief rate: €263 × 30% = €79
-
Tax benefit: €79 × 20% = €16
Result: Emma receives €16 annual tax relief.
Advanced Calculation Considerations
Leap Year Adjustments
Leap years require using 366 days in the denominator rather than 365, slightly reducing proportional calculations and affecting final relief amounts for identical circumstances.
The impact varies based on working day counts and total expenses, typically reducing relief by €1-€5 annually for most workers, though professional calculation ensures accurate leap year management.
Shared Expense Calculations
When utility bills are shared between multiple people, calculations must reflect individual payment responsibility rather than total household costs.
Shared expense situations require careful apportionment based on actual payment arrangements, creating complex calculations that professional services manage efficiently.
For complete details on qualifying expenses, see Expenses Covered Under Remote Work Tax Relief Ireland 2025.
Variable Employer Allowances
Some employers provide variable allowances based on working frequency, seasonal patterns, or changing business needs, requiring comprehensive tracking and accurate annual calculation.
Variable allowance coordination ensures accurate deduction from relief calculations while optimising overall tax efficiency across changing employer contribution patterns.
Multi-Property Calculations
Workers who change residence during the tax year require separate calculations for each property, with proper apportionment of expenses and working days across different locations.
Multi-property situations create unique calculation challenges that professional services manage through comprehensive tracking and optimal apportionment procedures.
Common Calculation Errors
Utility Cost Underestimation
