The first double payment for pensioners, carers, job seekers, and people with disabilities will be paid in the week of October 28, while the Christmas bonus will be paid in the week of December 2.
Minister for Social Protection Heather Humphreys is set to confirm the payment dates for the cost-of-living supports announced in the Budget.
The Finance Bill and the Social Welfare Bill, which will give effect to the measures announced in the Budget when they are passed by the Oireachtas in the coming weeks, are to be presented to the Cabinet.
When the bills will be enacted, and whether the legislation might be accelerated to pave the way for an election, is not yet clear, but some payment dates have now been nailed down.
The two double child benefit payments will be made on 5 November and 3 December.
On the week beginning 4 November, four payments will be issued, including the €400 Working Family Payment, the €400 Disability Support Grant and the €300 lump sum for households in receipt of the fuel allowance.
The following week, beginning on 11 November, will see a €400 lump payment issued to carers and a €200 Living Alone Allowance paid to widows, widowers and other single person households.
The €100 lump sum for people in receipt of the Child Support Grant will be paid on the week of 25 November.
Minister for the Environment Eamon Ryan will also tell the Cabinet that the €125 energy credits will be paid from the beginning of November and again at the start of January.
