Under Portuguese law, employers must compensate employees for the extra costs of working from home, and up to €1 a day is tax-exempt when the payment meets legal conditions: €0.10 for electricity, €0.40 for internet, and €0.50 for equipment. That works out to roughly the standard monthly amount over a typical work month, with a potential increase if a collective bargaining agreement applies an additional uplift. To keep those payments exempt employers need a written telework agreement or documented expense evidence, plus correct reporting on the monthly wage declaration (DMR).
TL;DR:
- The tax-exempt telework allowance in Portugal is capped at about €1 per day, covering electricity, internet, and equipment costs, provided proper documentation exists.
- Employers must have a written telework agreement linking the allowance to actual expenses for it to stay exempt from taxes and social security.
- Costs already covered by the employer, such as a company-provided laptop or direct internet payment, cannot also qualify for exemption.
- The allowance is calculated by summing daily caps of €0.10 for electricity, €0.40 for internet, and €0.50 for equipment, then multiplying by the number of full telework days.
- Failing to document expenses or having a flat allowance without an agreement risks reclassification as taxable salary, increasing payroll and compliance risk.

What Does Portuguese Law Say About Home Office Compensation?
The legal duty to pay for telework expenses comes straight from the Labour Code. Article 166.º requires a written telework agreement between employer and employee, and Article 168.º obliges the employer to cover the additional costs that working from home actually creates, things like higher electricity use, personal internet, and the equipment needed to do the job. This isn’t a fringe benefit an employer can choose to skip. It’s a statutory cost of letting someone work outside the office, and CMS’s overview of Portuguese remote work law confirms employers must cover systems, equipment, and the increased energy and internet costs tied directly to remote work.
Portaria n.º 292‑A/2023 turned that general obligation into hard numbers, setting the daily tax-exempt caps that employers now use to calculate payments without triggering income tax or social security contributions, as set by official Portuguese regulation. The Portuguese Tax Authority’s binding guidance under PIV_25747 confirmed that amounts within those limits are not taxable income, provided the underlying agreement and conditions are met, and it specifies how these amounts should appear on payroll reporting.
Three things employers should take away from this framework:
- The compensation duty exists regardless of company size or sector.
- The tax exemption is conditional, not automatic. Skip the paperwork and the payment becomes taxable salary.
- Circular Letter No. 20249 draws a line between amounts based on documented proof of expenses and amounts paid as a flat allowance, and the tax treatment differs slightly depending on which method a company uses.
Which Home Office Expenses Actually Qualify?
Four categories count toward the tax-exempt allowance, and Portuguese guidance treats them as an exhaustive list rather than a starting point:
- Residential electricity used for work.
- Personal internet service.
- Computer equipment or its equivalent (a laptop, monitor, or similar work tool).
- Maintenance costs tied to that equipment, which are typically considered part of the overall equipment expenses.
How a company structures the payment changes its tax treatment. A fixed monthly allowance stays exempt only if it’s written into an individual telework agreement or a collective bargaining agreement, with an amount that reasonably reflects the categories above. Pay it as evidence-based reimbursement instead, and the employer needs receipts or a documented calculation tying the payment to real expenses. Skip both routes, and the Tax Authority can reclassify the payment as ordinary salary.
Pro Tip: If your company already provides a laptop or pays the employee’s internet bill directly, don’t also pay the €0.40 or €0.50 allowance for that item; the exemption only covers costs the employee is actually bearing.
How Do You Calculate the Home Office Allowance?
The math is simple once you know the three components. Portaria n.º 292‑A/2023’s daily caps add up like this:
- Electricity per telework day
- Internet per telework day
- Equipment and maintenance per telework day
- Daily total sum
- Monthly total calculated by multiplying daily total by actual telework days
Worked example 1: An employee teleworks the full month and receives a fully exempt amount based on the standard daily cap.
Worked example 2: If a collective bargaining agreement applies, an increased daily cap may apply, raising the total exempt monthly amount accordingly.
For partial months or mixed office/home schedules, pro-rate by counting only full telework days, generally defined as a day covering at least one-sixth of the employee’s weekly working hours. An employee who works from home three days a week on a 40-hour contract gets the allowance for those three days only, not the other two spent in the office. If the employer already covers internet directly, drop the internet component from the calculation and pay only the electricity and equipment portions, with the daily exempt amount adjusted accordingly.
How Should Payroll Record and Report These Payments?
Payroll needs three things on file: the written telework agreement, a record of days worked remotely, and the payroll processing receipt showing the exempt amount was calculated correctly. That receipt, not the employee’s personal utility bill, is what the tax authority treats as the relevant document, according to Garrigues’s analysis of the clarified PIT framework.
Reporting has shifted slightly over time. Earlier guidance pointed payroll teams toward code A23 on the monthly wage declaration (DMR) for these exempt amounts; current administrative practice increasingly directs exempt telework compensation toward code A27, and payroll software or your accountant should confirm which code your current DMR template expects.
| Item | Requirement |
|---|---|
| Written agreement | Required under Article 166.º before fixed allowances qualify for exemption |
| DMR code | A23 historically; A27 under evolving current guidance |
| Supporting document | Payroll processing receipt, per PIV_25747 binding guidance |
| Payment timing | Due immediately following the expense period, per OCC guidance |
Timing matters as much as the amount. Compensation is due right after the expense arises, meaning most companies fold it into the same month’s payroll run rather than settling it quarterly or annually.
What Happens When the Employer Covers Equipment Directly?
Once an employer supplies the laptop, monitor, or pays the internet bill outright, that specific slice of the allowance disappears for the employee. CMS’s guide to remote work rules is explicit that costs already covered by the employer don’t also qualify for the employee-side tax exemption. Paying both would mean compensating the same expense twice.
A few practical edge cases come up often:
- Part-time and mixed schedules: only count full telework days, generally at least one-sixth of weekly contracted hours, toward the allowance.
- No written agreement: a flat monthly top-up paid without a signed telework agreement risks being treated as taxable salary, adding both income tax and employer social security exposure.
- No expense link: if a fixed allowance bears no reasonable relationship to actual costs incurred, the tax authority can challenge the exemption even when an agreement exists.
Employer Compliance Checklist for Telework Payments
Getting this right comes down to a handful of concrete steps, not a vague sense of “being compliant.”
- Draft a written telework agreement covering hours, equipment ownership, and the specific allowance amount, satisfying Article 166.º.
- Define what counts as a full telework day in that agreement, ideally the one-sixth weekly-hours threshold, to avoid later disputes.
- Choose either the fixed-allowance route or the evidence-based reimbursement route, and apply it consistently across the team.
- Confirm which DMR code your payroll system uses for exempt telework compensation, and verify it against current guidance rather than assuming last year’s code still applies.
- Retain payroll processing receipts as your primary compliance document, not employee utility bills.
Pro Tip: Run a quarterly audit of telework payments against your written agreements; mismatches between what’s paid and what’s documented are exactly what draws scrutiny during a labor or tax inspection.
Companies managing this manually across even a handful of remote employees often find the DMR coding and agreement paperwork harder to keep consistent than the math itself. An Employment Cost Calculator can help estimate the full cost of a Portuguese hire, telework allowances included, before you commit to a headcount plan. And if your payroll team needs a broader reference, this payroll compliance checklist for hiring in Portugal covers the documentation steps beyond just telework pay.
Why Formalizing Telework Pay Protects Both Sides
Portugal’s telework tax rules are more layered than most EU peers, and academic analysis of the framework points to that complexity as a real source of employer error. A signed agreement and a clean payroll trail aren’t bureaucratic overhead. They’re what stands between a routine allowance and a reclassified tax liability during an audit. Employers who treat the paperwork as optional are the ones who end up paying twice, once to the employee and once to the tax authority.

FAQ
How Do I Calculate My Portugal Home Office Compensation?
Add the three daily caps set by Portaria n.º 292‑A/2023: €0.10 for electricity, €0.40 for internet, and €0.50 for equipment, giving €1 per telework day.
What Law Regulates Telework in Portugal in 2026?
The core rules sit in Articles 166.º and 168.º of the Portuguese Labour Code, which require a written telework agreement and employer coverage of additional remote-work costs. Portaria n.º 292‑A/2023 sets the specific tax-exempt daily amounts that apply under those articles.
How Much Does a 20-Hour Part-Time Job Pay in Portugal?
Part-time pay depends entirely on the role, sector, and hourly rate agreed in the contract, since Portugal sets no fixed part-time salary schedule. For telework compensation specifically, a part-time employee working from home only receives the daily allowance for days that meet the full-telework-day threshold, generally at least one-sixth of their weekly contracted hours.
Can I Earn Money Working From Home in Portugal?
Yes, both as an employee under a telework agreement with your employer or as a self-employed worker, though the tax-exempt home office allowance discussed here applies specifically to employees compensated by an employer for teleworking costs. Self-employed individuals follow separate expense deduction rules rather than the Portaria 292-A/2023 caps.
What Happens if There’s No Written Telework Agreement?
Without a signed agreement, a fixed monthly telework allowance loses its tax-exempt status and can be reclassified as ordinary taxable salary. That exposes both the employee to extra income tax and the employer to added social security contributions, according to CMS’s guidance on remote work risk.
