The eForm 12 2013 is the electronic version of the paper Form 12 2013 (PDF, 1.85 MB) and allows you to complete a return of your income and claim tax credits, allowances & reliefs (including any health expenses) electronically for the year ended 31 December 2013.
It is to be completed by a person whose main source of income is from a PAYE employment or pension or a non-proprietary company director who pays all his or her Income Tax under the PAYE system.
The electronic form is simpler to complete than the paper version. It will include certain important information from your Revenue record to help you complete your Return. You only need to complete the sections of the Form that are relevant to you.
