Can I extend my work visa in Ireland if I earn a good amount?

No, earning a high income does not automatically allow you to extend your work visa in Ireland.

Work visa extensions are generally based on specific circumstances, such as waiting for a work permit decision or facing significant personal issues - not your salary. You must apply for an extension while you are still in Ireland and before your current visa expires.

Extensions are discretionary and not guaranteed. Plan ahead and consider applying for a new employment permit or visa before your current permission runs out to avoid gaps in your legal status.
