This one arrives as a shock because it looks like a mistake. The payment is described as taxable, nothing is deducted from it, and then a tax credit certificate turns up with your credits cut and your rate band shortened. Nothing has gone wrong. That is the mechanism.
The short version
- Is it taxed?
- Yes, Maternity Benefit is taxable
- USC and PRSI
- Neither applies to it
- Deducted at source?
- No. The Department pays it to you in full
- How the tax is collected
- By reducing your tax credits and rate band
- Do you declare it?
- No. The Department tells Revenue directly
- Also taxable
- Paternity, Parent's, Adoptive and Health and Safety Benefit
- Who decides
- Revenue sets the credits; the Department pays the benefit
Nothing is taken out of the payment itself
Citizens Information is unambiguous: the Department of Social Protection does not take any tax from your social welfare payment before it is paid to you. Maternity Benefit lands whole. Neither the Universal Social Charge nor PRSI applies.
So if your only income for the year were Maternity Benefit, you might well pay no tax at all, because claiming a social welfare payment also gives you the Employee Tax Credit on top of your normal credits. Tax is only really in play when the benefit sits alongside other income.
The tax comes out of your credits instead
Here is the sentence that explains the certificate: "Social welfare payments are taxed by reducing your tax credits and rate band." Revenue's term for it is coding in.
Your employer keeps taxing your salary through PAYE exactly as before. To collect the tax owed on the benefit, Revenue shrinks the credits and, on higher incomes, the standard rate cut-off point that your salary is taxed against. The result is more tax deducted from your pay, without your pay having changed. It looks like a pay cut and it is a tax collection.
The alternative is worse, which is worth knowing before you resent it. If the benefit were not coded in, you would be treated as a self-employed person for it and would owe the tax in a lump sum by 31 October the following year.
You do not declare Maternity Benefit to Revenue. The Department notifies Revenue of these payments, so it reaches your record without you doing anything. That is also why the figures can be wrong without anyone lying to you: they are an estimate of what Revenue expects you to receive.
If the numbers on the certificate look wrong
Because the reduction is calculated from the benefit Revenue expects you to get, the reduction is only as accurate as that expectation. It is worth reading the certificate properly rather than filing it: check that the benefit figures on it match the number of weeks you are actually going to be paid, and the payments you are actually getting.
If they do not match, that is a question for Revenue, who set the credits, rather than for your employer or the Department. Your employer only applies what the certificate tells them, and the Department only reports what it pays.
Which family payments are taxed
Every one of these is on the same mechanism. The split is not intuitive, so it is worth seeing it in one place:
- Taxable: Maternity Benefit, Paternity Benefit, Parent's Benefit, Adoptive Benefit, Health and Safety Benefit, and One-Parent Family Payment.
- Not taxed: Child Benefit, and Fuel Allowance.
So the two payments most parents receive land on opposite sides: the one you claim for the leave is taxable, and the monthly one for the child is not.
If your employer tops up your pay
Many employers continue paying you during maternity leave and have the benefit paid to them instead. Where that happens, the tax on the combined amount is handled through your payroll in the normal way. Our guide to maternity leave and Maternity Benefit covers how that arrangement works and what to confirm with your employer.
Who decides
Revenue decides your tax credits and rate band and issues the certificate. The Department of Social Protection decides and pays the benefit, and reports it to Revenue. This page explains a mechanism; it is not tax advice and it cannot tell you what you personally will owe. For a question about your own certificate, Revenue is the authority, and a qualified tax adviser is the route if the position is complicated.
