Benefits will land in people's accounts early due to the bank holiday for the Queen's state funeral.
There will be a national public holiday on Monday to allow Brits to pay their respects to the country's longest serving monarch.
The Queen will lie in state in Parliament's Westminster Hall ahead of the funeral, with hundreds of thousands of mourners expected to file past her coffin over four days.
The late sovereign will be borne to Westminster Abbey in a procession for the ceremony at 11am on Monday.
Government guidance suggests businesses and event organisers can decide whether to remain open during the ceremony - but they are advised to consider rescheduling plans that clash with the funeral.
The Department for Work and Pensions has confirmed that payments of benefits due to land in accounts on Monday will be made early.
People who are due to receive payments on Monday 19 September will instead be paid on Friday, 16 September, the last working day before the State Funeral.
It follows standard DWP and HMRC rules that see benefit and credit payment dates brought forward in line with national bank holidays.
The full list of payments affected are:
- Attendance Allowance
- Carer’s Allowance
- Disability Living Allowance
- Employment and Support Allowance
- Income Support
- Industrial Injuries Disablement Benefit
- Jobseeker’s Allowance
- Pension Credit
- Personal Independence Payment
- State Pension
- Universal Credit
- Child Benefit/Guardian’s Allowance
- Working Tax Credits
- Child Tax Credits
The Government has frozen almost all public facing activity over the 10-day national mourning period, which will draw to a close after the Queen's funeral.
Parliament rose early after two days of tributes to the late monarch and will not sit again until next week.
However vital work must continue in the background on issues such as the cost of living crisis.
New Prime Minister Liz Truss is still expected to unveil a mini Budget next week, setting out details on her plan to freeze annual energy bills at £2,500 for a typical household over the next two years.
She is also expected to flesh out her tax cutting proposals, which were at the centre of her successful Tory leadership bid.
But timing is very tight, as Ms Truss is also due to attend the UN General Assembly in New York - and Parliament is set to rise on Thursday for the annual party conference season.
