a practical question about capital grant accounting

Dear Tutor,

I have a question about the capital grant accounting. I hope you can help me with it. This is not an acca exam question, but I got it from work.

“A budget holder in authority rings me for some financial advice. They received a capital grant into the Authority in March 2019 but will not spend it until the next financial year.”

What advise can I give him in terms of budget allocation? How does the accounting of grant work? It should relate to next financial year, right?

Thank you so much in advance for your help.

Katie
