The Official Revenue Formula
Understanding the Core Formula
Revenue's Remote Working Relief Formula:
((A × B) ÷ C – D) × 30%
A = Total allowable utility bills
(electricity, heating, broadband)
B = 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.
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.
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
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
All domestic electricity consumption, including electric heating systems that serve home office spaces.
Heating Expenses
Gas, oil, solid fuel, and other heating systems that maintain comfortable working temperatures.
Broadband Costs
High-speed internet connectivity essential for remote working, including reasonable portions of bundled services.
Professional expense identification typically uncovers 15-25% more qualifying costs than self-analysis through comprehensive utility categorisation.
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.
✅ INCLUDE These Days
- • Full home working schedules
- • Partial home days meeting substantial work criteria
- • Home working due to weather or meetings
- • Approved remote work substituting office activities
❌ EXCLUDE These Days
- • Office working days
- • Annual leave
- • Public holidays
- • Sick leave (unless worked from home)
- • Weekend work outside normal hours
Professional day counting methodology often identifies 20-30 additional qualifying days annually through comprehensive classification.
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 These Employer Contributions:
Professional allowance coordination ensures optimal balance between employer payments and employee relief claims for maximum tax efficiency.
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.
Tax Benefit Calculation
Apply your marginal tax rate to the specified amount:
Standard Rate Taxpayers (20%)
€20
benefit per €100 specified amount
Higher Rate Taxpayers (40%)
€40
benefit per €100 specified amount
Understanding benefit calculation helps set realistic expectations while highlighting opportunities for strategic tax planning that enhances relief outcomes.

Advanced Calculation Considerations
Leap Year Adjustments
Leap years need using 366 days in the denominator rather than 365, slightly reducing proportional calculations.
The impact typically reduces relief by €1-€5 annually, 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.
Shared expense situations need careful apportionment that professional services manage efficiently.
Variable Employer Allowances
Some employers provide variable allowances based on working frequency, requiring comprehensive tracking.
Variable allowance coordination ensures accurate deduction while optimising overall tax efficiency.
Multi-Property Calculations
Workers who change residence need separate calculations for each property.
Multi-property situations create unique challenges that professional services manage through comprehensive tracking.
Common Calculation Errors
Utility Cost Underestimation
Self-calculation attempts frequently miss qualifying utility categories and underestimate costs.
Common omissions: Electric heating, broadband portions, seasonal variations.
Professional analysis eliminates these errors.
Working Day Miscounting
Inaccurate day counting represents the most common error, undercounting by 15-30%.
Common mistakes: Excluding occasional work, misclassifying partial days.
Professional counting ensures comprehensive identification.
Formula Application Errors
Mathematical errors in formula application reduce final relief amounts.
Complex formulas create numerous opportunities for calculation errors.
Professional services eliminate mathematical errors.

Frequently Asked Questions (FAQ)
How do I calculate relief if I work different days each week?
Count all actual home working days regardless of schedule variability. The formula accounts for irregular patterns by using total annual working days.
What if my utility bills don't align with the tax year?
Use bills that cover the tax year period, pro-rating partial bills if necessary. Professional services manage billing cycle alignment to ensure accurate calculation.
Can I use estimated utility costs if I don't have all bills?
Revenue needs actual utility bills for relief claims. Estimates aren't acceptable, though professional services can help reconstruct missing documentation.
How do I calculate relief for shared accommodation?
Include only your portion of shared utility costs based on actual payment responsibility. If you pay 50% of household bills, use 50% in calculations.
What happens if my calculation shows negative relief?
If employer allowances exceed your calculated specified amount, you simply receive the tax-free employer payments without additional relief claims.
Do I need to recalculate if my circumstances change?
Circumstance changes during the year need updated calculations using actual figures. Professional services manage changes while optimising relief.
