Officials from The Pensions Regulator (TPR) and Pension Protection Fund (PPF) will give evidence to MPs about British Home Stores (BHS) on 9 May.
The Work and Pensions Committee also intends to hear from the BHS pension trustees and Retail Acquisitions head Dominic Chappell.
It will speak to these groups of witnesses ahead of former owner Sir Philip Green who has indicated his willingness to give oral evidence in parliament.
In a letter from committee chairman and MP Frank Field (pictured above) to Green, Field suggested 15 June as a potential date for him to appear before the committee but no firm date has been settled on yet.
Field also confirmed in the letter there were now no plans to invite Green's wife Lady Green to give evidence.
These proceedings are part of an inquiry by the select committee into pensions regulation and the impact of the BHS liabilities on the PPF if it absorbs the scheme.
There have been discussions about who is to blame for the situation with a number of experts arguing trustees at BHS did the best they could under the very difficult circumstances.
The Business, Innovation and Skills Committee launched a separate inquiry looking into the sale and acquisition of BHS on 28 April.
Its chair and MP Iain Wright said: "The sale and acquisition of BHS raises serious questions about the stewardship of the business both before, during, and after the sale. We welcome this opportunity to question the key players and we will also be keen to quiz advisers on their role in this process."

Opportunities for defined benefit (DB) schemes to pursue investment approaches that help repair the UK’s economy cannot stand in the way of improving member outcomes, Aegon says.
More members transferred out of defined benefit (DB) pension schemes in October after September's record lows while values were surprisingly stable, according to XPS Pensions Group's Transfer Watch.
Joanna Smith says trustees will need to accurately identify if covenant issues are short-term affordability concerns, or the start of more material deterioration.
