Trust accounts consolidation (TAC) data publications: background information


Information about previous trust account consolidation data publications and our process for future data consolidations.

Introduction to TAC data sets

The primary function of the trust accounts consolidation dataset is to collect data to enable production of our consolidated NHS provider accounts, and to collect data to support production of the Department of Health and Social Care’s (DHSC) group accounts.

This dataset existed for the first time in 2017/18. Each year beyond this will be a separate dataset.

The codes used to identify pieces of data (‘maincode’ and ‘subcode’) may change between years. The TAC dataset replaces two datasets for the years 2016/17 and earlier:

  • previously we collected foundation trust consolidation (FTC) data from NHS foundation trusts. Data publications from these processes are available in a collection on the Monitor website
  • the Department of Health and Social Care collected financial information and monitoring system data from NHS trusts. Data publications from these processes have been made available on the DHSC website.

Accounting policy changes and other significant developments

We have listed the major changes in accounting policy or other significant developments that affect the data each year compared to the previous year. This list is not intended to be exhaustive and we cannot assure the accuracy of any multi-year analysis a user may wish to perform.

Years prior to 2017/18

Information on major accounting changes for years prior to 2017/18 is provided in the background information as part of the FTC data collection on the Monitor website.


There were no significant changes to accounting standards applicable to 2017/18 compared to 2016/17.

This year saw the introduction of a new format for financial reporting data collection for NHS trusts and NHS foundation trusts. 


IFRS 9 and IFRS 15 were new standards implemented in 2018/19. Although the application of the standards did not have a material impact on the reported results for the sector, there was a significant effect on the presentation within the income and receivables notes included in the accounts. Further information on the implementation of the standards can be found in the DHSC Group Accounting Manual.
