Choose How You Want to Work
There are basically two methods of running a building business in Ireland: as a self-employed person (the most popular option) or as a company (we suggest registering Ltd company to open construction business in Ireland). When it comes to making the right choice, consider the following aspects:
- Whether you’re planning to hire employees or not – sole traders can be employers either, however, it’s better to register as a Ltd company
- Whether you’re looking to expand – entrepreneurs anticipating growth should register as Limited companies and enjoy the perks of owning a company
- Evaluate risk potential: Sole proprietors are solely liable for tax compliance and the debts of their enterprise (they will be obliged to sell their assets to pay off their debtors if the business stops generating income). If a limited liability company fails to pay its debts, the director’s private capital is inviolable and cannot be used to collect the debt.
