Introduction
Navigating your tax obligations as an Irish sole trader can feel overwhelming, especially with constant changes to PRSI rates and tax credits. This comprehensive guide answers the eight most searched questions by self-employed individuals in Ireland, providing up-to-date information for 2025. Whether you’re just starting out or looking to optimise your existing business, we’ll walk you through everything from payment deadlines and expense claims to VAT registration and record-keeping requirements. Each answer includes practical tips and direct links to official Revenue resources, helping you stay compliant while maximising your tax efficiency.
Important: We are not accountants, and this guide does not constitute professional tax advice. You should always consult your accountant regarding your specific circumstances.
1. When do I need to pay my self-employed tax in Ireland?
For Irish sole traders, here’s when you need to pay your self-employed tax:
The key deadline is 31 October each year, though you get a bit more time if you use Revenue Online Service (ROS); it’s extended to 14 November. On this date, you’ll need to handle three things:
- File your tax return for the previous year
- Pay any remaining tax you owe for that year
- Pay your preliminary tax for the current year
It’s wise to set aside about 35% of your income monthly to prepare for this.
For more detailed guidance, check out Revenue’s guide to self-assessment: Revenue Guide to Self-Assessment
A quick heads-up – if you miss the deadline, you’ll face interest charges (0.0219% daily) and potential surcharges of 5-10%, so it’s worth staying on top of these dates!
2. What expenses can I claim as a self-employed person in Ireland?
You can claim any expense that is wholly and exclusively for business use as a deduction against your taxable income. If an expense is only partly for business use, you can only claim the business-related portion.
Here are some key categories of allowable expenses:
Business Premises Costs:
- Rent and rates
- Utilities (heating, lighting, power)
- Insurance
- Security costs
Vehicle & Travel:
- Fuel, insurance, and repairs for business vehicles
- Business travel expenses (train, taxi, flights)
- Hotel accommodation for business trips
- Note: If using your car for both personal and business use, you can only claim the business portion.
- Note: If you’re a limited company, vehicle expenses are managed differently.
Professional & Financial:
- Accountancy fees
- Legal costs
- Bank charges and interest on business loans
- Professional indemnity insurance
Equipment & Supplies:
- Purchase of goods for resale
- Tools and equipment
- Repairs and maintenance
- Office supplies
Staff Costs:
- Employee wages
- Subcontractor costs
- Recruitment fees
- Employer’s PRSI
Working from Home:
You can claim a percentage of your household bills (heating, electricity, broadband) based on how much of your home is used for business.
Miscellaneous Business Expenses:
- Advertising and marketing
- Training courses related to your trade
- Website hosting and software subscriptions
- Any other costs necessary for running your business – for example, if you needed to hire a tiger for a photoshoot, that would be a legitimate business expense, but new carpets for your house wouldn’t qualify.!
Important: Keep all supporting documents (invoices, receipts, bank statements) for at least six years in case of a Revenue audit.
