Short answer: yes. If you work for yourself in Ireland and your income from self-employment is €5,000 or more in a year, you pay Class S PRSI. Earn less than that and you are exempt, although you can choose to pay €650 as a voluntary contributor to keep your record alive.
PRSI catches a lot of new sole traders off guard. Nobody deducts it for you, there is no payslip, and the first time most people meet it is on their Form 11. This guide covers who pays, how much, what you actually get for the money, and what goes wrong if you ignore it.
What does PRSI mean for sole traders and self-employed people?
PRSI stands for Pay Related Social Insurance. It is the charge that funds Ireland’s social insurance system, and every social insurance contribution you make is recorded against your PPS number. That record decides whether you qualify for the State Pension and a range of other social welfare benefits later on.
Employees have PRSI deducted through the PAYE system, usually at Class A. Self-employed people sit outside that machinery. You calculate and pay your own self-employed PRSI through self-assessment, alongside your income tax and USC.
This applies whether you call yourself a sole trader, a freelancer, or a contractor. For PRSI purposes they are all the same thing, though there are some legal distinctions worth knowing, which we cover in our guide to the difference between a sole trader and self-employed.
What PRSI class do sole traders pay?
Sole traders and other self-employed people pay Class S PRSI. The Department of Social Protection’s operational guidelines on PRSI for the self-employed confirm that Class S covers self-employed workers aged between 16 and 66, including sole traders, professionals, farmers, and certain company directors.
Class A PRSI, by contrast, is for employees. The two classes build up different entitlements, so knowing which one you are on matters. Plenty of people hold both at once: if you keep a part-time job while building a business on the side, you pay Class A on your wages and Class S on your trading profits. We have written before about whether you can be a sole trader and a PAYE employee at the same time, and the answer is yes.
How much Class S PRSI do I pay?
From 1 October 2025, the rate of PRSI for Class S is 4.2% of your total income for tax purposes, or €650, whichever is greater, according to Citizens Information. Total income here means your gross income less allowable expenses. Up to 30 September 2025 the rate was 4.1%, so a blended rate of 4.125%, or the minimum payment of €650, applies to 2025 self-employed annual income for anyone paying PRSI through the Revenue self-assessed system.
And it keeps climbing. The rate rises to 4.35% from 1 October 2026 under the Government’s planned schedule of PRSI rate increases.

Your situation |
What you pay |
|
Self-employment income of €5,000 or more |
4.2% of total income or €650, whichever is greater (from 1 October 2025) |
|
2025 annual income (rate changed mid year) |
Blended rate of 4.125%, or the €650 minimum |

Over €5,000 but told by an Inspector of Taxes you need not file a tax return |
Flat rate contribution of €310 paid directly to the Department of Social Protection |
|
Self-employment income under €5,000 |
Exempt, with the option to pay €650 as a voluntary contributor |

From 1 October 2026 |
Rate rises to 4.35% |
That €650 minimum trips people up. Even in a lean year where 4.2% of your profit works out at €300, you still owe €650 once over the €5,000 threshold. A flat rate floor, not a percentage.
Do I pay PRSI if I earn under €5,000?
No. If your income from self-employment comes in under €5,000 for the year, you are exempt from Class S PRSI. The catch: an exempt year is a blank year on your social insurance record, and blank years can cost you a chunk of your State Pension decades later.
That is why Citizens Information flags the option to pay €650 as a voluntary contributor if you meet the conditions. For someone with a small side business, paying voluntarily can be one of the cheapest ways to keep pension entitlements ticking over. If you are weighing this up, our guide on how much a sole trader can earn before paying tax covers the related income tax thresholds.
What benefits does Class S PRSI cover?
Your Class S contributions are not just another tax. They buy real cover, including:
- State Pension (Contributory), the big one for most self-employed people. Eligibility rules are on the State Pension (Contributory) page.
- Jobseeker’s Benefit (Self-Employed), if your business closes or you have to stop trading.
- Maternity Benefit, Paternity Benefit, Parent’s Benefit and Adoptive Benefit.
- Invalidity Pension and Treatment Benefit (dental and optical).
- Widow’s, Widower’s or Surviving Civil Partner’s (Contributory) Pension.
Class S does not cover everything Class A does. Illness Benefit and Occupational Injuries Benefit are the notable gaps, which is why many self-employed people take out income protection separately. And if you are moving from a welfare payment into self-employment, the Back to Work Enterprise Allowance can ease the transition while your welfare entitlements adjust.
How and when do I actually pay it?
There is no separate PRSI bill. You pay Class S PRSI as part of your annual self-assessment return to Revenue, and Revenue’s guide to PRSI under self-assessment confirms it is collected with your income tax. In practice that means:
- You register for self-assessment with Revenue when you start trading.
- You file a Form 11 tax return each year by 31 October (later if you file and pay through ROS).
- Your PRSI is calculated on the return and paid with your income tax and preliminary tax for the current year.
Started trading mid year? You are still assessed on that year’s profits, however many months you actually traded. Profits fluctuate, and your annual PRSI contribution moves with them, subject always to that €650 floor. If Form 11 season fills you with dread, our tax return accountants handle the whole filing, PRSI included. While you are at it, check whether you also owe USC when you run your own business.
How do I check my PRSI record?
Every contribution is recorded against your PPS number by the Department of Social Protection. You can request a statement of your contributions through MyWelfare.ie using a verified MyGovID account. Check it every few years; gaps are far easier to fix while the paperwork is fresh than when you are claiming a pension.
What happens if I do not pay PRSI?
Gaps in your record reduce or delay your benefits. Citizens Information is blunt about the pension consequence: your State Pension (Contributory) will only be paid from the date you have paid all outstanding contributions and any outstanding income taxes in full. Skipping PRSI in your thirties can quite literally postpone your pension in your sixties.
You generally stop paying at age 66, although if you defer claiming your State Pension you can keep contributing up to age 70 to improve your entitlement. Until then, treat it as compulsory insurance, priced well below anything a private insurer would quote.
FAQs about PRSI for the self-employed
Is a sole trader the same as self-employed for PRSI?
For PRSI purposes, yes. A sole trader is simply one form of self-employment, and both pay Class S on the same basis. The terms differ slightly in legal and registration contexts, but the Department of Social Protection treats them identically.
If I am employed and self-employed, do I pay PRSI twice?
You can pay under two classes in the same year: Class A on your employment earnings through the PAYE system and Class S on your self-employed income. Each builds your record, though entitlement rules differ between classes, so check your specific situation.
Can I pay PRSI voluntarily if I am exempt?
Yes, subject to conditions. If you earn under €5,000 from self-employment you may pay €650 as a voluntary contribution to protect your record. Citizens Information’s guide to becoming self-employed explains the process.
How many PRSI contributions do I need for the State Pension?
You need a minimum of 520 paid contributions, which is ten years’ worth, and your final pension rate depends on your full contribution history. Check your record early rather than at retirement.
Want to confirm your PRSI obligations as a sole trader?
If your self-employed income is over €5,000, plan for Class S at 4.2% or the €650 minimum through your next return. If you are under the threshold, decide whether a voluntary contribution makes sense for your pension. Either way, pull your income figures together, confirm you are registered with Revenue, and look at your contribution record on MyWelfare.
