Official DSP eligibility parameters
\text{Weekly Shortfall} = \max\Big(0, \text{DSP Child Income Threshold} - \text{Net Weekly Family Income}\Big) \\
\text{Weekly WFP Payment} = \max\Big(€20, \lceil \text{Weekly Shortfall} \times 60\% \rceil \Big) \\
\text{Annual Tax-Free Cash} = \text{Weekly WFP} \times 52 \text{ Weeks} \quad [100\% \text{ Tax-Free}]The Working Family Payment (WFP, formerly Family Income Supplement) is a weekly tax-free payment for working families with dependent children. You must work at least 38 hours every fortnight (combined or single). If your net weekly household income falls below the official DSP threshold for your family size, the State pays 60% of the difference (minimum €20/week), fixed for 52 weeks regardless of minor pay changes.

No! Working Family Payment is 100% tax-free. It is not subject to PAYE Income Tax, USC, or PRSI deductions and is paid directly into your bank account.
No! Universal Child Benefit (€140/month per child), Housing Assistance Payment (HAP), and the Fuel Allowance are legally disregarded and not counted as income when assessing your WFP application.
Once granted, WFP is guaranteed for 52 consecutive weeks. If your earnings increase or you earn extra overtime during that 1-year period, your weekly WFP amount remains completely unaffected until annual review.
