The publication of the revised Compact, which sets out how voluntary and public sector organisations should behave towards each other, has been delayed.
The new version, which at 56 pages is a third of the size of the original document, was expected to be unveiled during Compact Week from 2 to 8 November.
But a Cabinet Office spokeswoman said it now expected the launch to take place "before the end of the year".
She said: "Some particularly interesting and complex issues arose during the consultation." She declined to say what they were.
"We are taking the necessary time to ensure that the refreshed Compact resolves these issues and fully meets the needs of both the public sector and the third sector," she said. "Rushing to a premature response would be of no benefit to anyone."
A 12-week consultation on the future of the Compact, which closed last week, attracted about 100 responses. Some organisations, including Voice4Change England, were concerned about proposals to abolish the codes of good practice.
Oliver Reichardt, head of the Compact team at Compact Voice, said: "Our priority is to properly consider the views of the voluntary sector and ensure that we deliver the best possible Compact. Taking time to get it right is the most important thing; the timetable must be what's best for the Compact."
