Filing a Form 11 is required for self-assessed individuals in Ireland but many people don’t know where to begin. This section answers the most common questions about what it is, who needs to file it, and how to get it done correctly.
You can apply to be excluded from the obligation to submit your return electronically if you don’t have the internet or due to old age.
All Form 11’s must be submitted electronically unless you receive an exemption from Revenue.
The extended Form 11 deadline for e-filing vis ROS or using FastTax.ie is Wednesday, 19th November 2025. FastTax.ie makes it easy to complete your Form 11 and manage your filing obligations.

Pay Related Social Insurance (PRSI)
