8 Realistic Side Incomes for Irish Adults in 2026
According to the Central Statistics Office, over 340,000 Irish adults hold a second income source or side work outside their main employment. Yet most remain uncertain which options actually stack up financially—or what Revenue.ie expects of them. This guide strips away the hype and shows you eight side incomes that work in Ireland right now, with honest timings, effort levels, and the tax reality you need to know.
1. Pet-Sitting and Dog Walking
Pet-sitting is one of the most reliable side incomes for people in Ireland with flexible schedules. Apps like Rover and local services such as DogBuddy connect you with pet owners willing to pay €15–€25 per 30-minute walk, or €40–€70 per day for minding pets while owners are away. A Dublin-based pet-sitter we spoke to averaged €400 per month by walking dogs four times weekly in her neighbourhood.
The tax angle: Income over €1,000 per year is taxable. Register as self-employed with Revenue.ie if you exceed that threshold.
2. Freelance Writing and Content Creation
If you can write, platforms like Contently, Mediavine, and local Irish publications (Irish Examiner freelance pool, TheJournal.ie contributors) pay between €50 and €300 per article depending on length and publication. Building a portfolio takes 2–3 months, but once established, a reliable freelancer can earn €600–€1,200 monthly.
Real calculation: Sarah, a communications officer in Cork, writes one 1,500-word feature per week for an online magazine at €150 per piece. That's €600 monthly, or €7,200 yearly—well below the €20,000 self-employment threshold where she'd owe income tax, but she still registers as self-employed to claim tax relief on her home office and equipment.
3. Short-Term Rental of Parking Space or Driveway
In Dublin, Cork, and Galway, parking is a pain point. If you own a driveway or garage, listing it on JustPark or ParkWhiz can generate €80–€150 per month. A south Dublin homeowner with a single space close to Luas reported consistent bookings at €100 monthly—€1,200 per year with minimal effort.
The catch: This counts as rental income and must be declared to Revenue. However, owner-occupied properties benefit from the Rent-a-Room Relief scheme (up to €14,000 per year in certain cases), though parking falls into a grey area—contact a tax advisor or your local revenue office to confirm your liability.
4. Online Tutoring and Test Prep
With the leaving certificate and competitive third-level entry, Irish parents pay well for maths, English, and languages tutoring. Wyzant, Chegg, and local platforms like Tutor.com pay €15–€25 per hour; private tutoring (advertised locally or via word-of-mouth) can reach €30–€50 per hour. A part-time tutor taking ten students at €25/hour for one hour per week earns €1,000 monthly.
What you need: You'll typically need a bachelor's degree and a clear DBS check (Garda vetting). It's flexible, tax-deductible (materials, travel), and highly scalable.
5. Affiliate Marketing and Niche Websites
This is the longest road to meaningful income, but it works. Building a niche Irish blog or YouTube channel around money, property, gardening, or parenting, then monetising via affiliate links and ads, can generate €200–€500 monthly after 12–18 months of consistent work. A Waterford-based gardener built a site on composting and permaculture, earning €300 monthly in affiliate commissions by year two.
Realistic expectation: Expect zero income for the first 6–9 months. This suits people who enjoy writing and are patient with delayed returns.
6. Reselling on Vinted, eBay, and Etsy
Whether you're upcycling furniture, selling vintage clothes, or hand-making crafts, online marketplaces are proven income channels. A part-time reseller in Dublin shifting €50–€150 worth of items weekly nets €150–€300 monthly after fees and postage. Etsy shop owners selling handmade goods (jewellery, prints, candles) can average €400–€800 monthly with strong marketing.
Tax note: Casual selling is usually okay up to a point, but if it becomes habitual and profit-focused, you're trading—register with Revenue and claim business expenses.
7. Freelance Virtual Assistance
Busy entrepreneurs and small business owners in Ireland hire virtual assistants for email management, scheduling, social media, and bookkeeping. Rates start at €12–€18 per hour for general admin, climbing to €25–€40 per hour for specialised tasks like bookkeeping or copywriting. A part-time VA working 10 hours weekly at €16/hour earns €160 per week, or roughly €650 monthly.
Platforms include Upwork, Fancy Hands, and local Irish communities on LinkedIn and Facebook.
8. Cash-Back and Rewards Apps
While not a serious income driver, apps like Cashback Office, TopCashback, and Irish grocery loyalty schemes (Tesco Clubcard, Dunnes Everyday Plus) do add up. Realistically, you're looking at €30–€80 per month if you're deliberate about it. It's passive, requires no tax return (under miscellaneous income thresholds), and perfect for offsetting everyday spending.
Tax, National Insurance, and Registration
According to Citizens Information, if you earn under €1,000 from self-employment annually, you don't legally need to register—but many advisors recommend it for protection and record-keeping. Over €1,000, registration is mandatory. You'll owe income tax at the standard rate (20%) or higher rate (40%) depending on your main employment income, plus 4% employer + 8% employee PRSI (if applicable).
Keep all receipts, track mileage and expenses carefully, and use an accountant (€150–€300 annually) or free tools like Revenue's PAYE Services to file your return. One honest note: many people underestimate their tax liability—budget for a chunk of your side income to go to Revenue.
Frequently Asked Questions
Do I need to tell my main employer about side income?
Not legally, unless your employment contract prohibits it (check your paperwork). However, if you receive taxable side income, you must declare it to Revenue. Your main employer isn't notified, but Revenue may flag unusual tax returns if you don't.
Can I claim a home office deduction for side income?
Yes. If you use a dedicated room or desk for self-employed work, you can claim a proportion of rent, utilities, and broadband as business expenses. Revenue suggests either €4 per week (flat rate) or an actual calculation with proof. Keep records.
What's the most realistic monthly income from side work in Ireland?
That depends entirely on your skill, time, and market. Pet-sitting or tutoring can reliably deliver €400–€800 monthly within 2–3 months. Affiliate sites or reselling can take longer but may scale to €500–€1,500+ after a year. Don't expect overnight results—consistency beats hype.
Making side income in Ireland is achievable, tax-legal, and increasingly common.
