The latest numbers compare to a £5.4m loss in the previous year from a turnover of £215.9m.
The company blamed the figures on project delays caused by second staircase rules and build cost inflation.
Further provisions were also made for building safety remediation work with £18.96m now set aside for post-Grenfell upgrades.
Higgins restructured the business during the year with £1.1m spent on redundancy payouts.
The firm said: “Higgins Partnerships project delivery was segmented into regions resulting in a significant improvement in operational efficiency whilst providing a strong platform for growth.
“The business will reap the benefit of the restructure in our current financial year.”
