The amount of capital which is disregarded varies, depending on what scheme you apply for.
As Berni said, for Jobseeker Allowance claims, the first €20,000 is disregarded.
For Supplementary Welfare Allowance claims, the first €5,000 is disregarded.
For Disability Allowance claims, the first €50,000 is disregarded.
If you're claiming Jobseeker's Benefit, based on your PRSI contributions, then you won't be means-tested on your capital at this time.
