How to Treat Treasury Bill/Fixed Deposit Investment in QuickBooks

Growing a business isn’t all about increasing sales from operating activities, which up till now remains the best strategy to sustain the business, but investing some of the available cash in your bank in safe and secure investment opportunities that generate passive income. After all, your cash is subject to inflationary risk if it is kept in a savings account where interest rates at an all-time low (2-3%) per annum.

The cash generated from sales didn’t come in as a donation or gift from customers, you dissipated efforts,  and value to ensure your customers feel satisfied, so a high-risk investment like the stock isn’t one you should even consider, rather it is safer to keep your funds in risk-free assets like FGN bonds or CBN Treasury Bills, an investment that is fully backed by the federal government.

As a business owner, you are strongly advised to keep track of all these investments in your books so you can easily track the cash flow, also known as interest income from various risk-free investments. One of the best software for managing “fixed income investments and interest earned” is QuickBooks.

We had just helped a corporate society, who invest members’ savings/thrift primarily in CBN Treasury Bills and Fixed Deposit with interest paid upfront into the account, migrate their 12-months transactions from excel into QuickBooks Online.

Here are three scenarios, we treated during the data migration:

  • Investment in Treasury Bills with Interest paid upfront.
  • Rollover of maturing investments with interest.
  • Additional investment in Fixed Deposit/Treasury bills
  • Liquidation of existing holdings on maturity

Basic Setup:

The relevant bank accounts have been set up to track all fund flows in and out of the account while CBN Treasury Bills/Fixed Deposit investments are added to the “Chart of Account” under Assets.

Investment in Fixed Deposit/Treasury Bills with Interest Paid Upfront

All investment in Treasury Bills is treated under the “Write Cheque Window” where payment is debited from a specific bank account and moved to the investment account, depending on the amount invested.

The interest paid upfront was also treated accordingly using “Journal Entry” as thus:




For interest received into the bank account but wasn’t fully earned in the current financial year, we had to prorate the interest using the maturity period to ascertain the amount to be recognized in the current year while the balance is treated as income received but no earned (under current liability) until the investment matures.

For instance, assuming the CBN T-Bills is for 365 days but the financial year end period from the start of the investment is only 100 days.

(100/365) x N19,200,000 = N5,341, 600.

The balance of N13, 858, 400 is treated as “Income Received but Not Earned“.

Rollover of maturing investments.

We were also informed that a mail is sometimes sent to the asset management company requesting that the CBN Treasury Bill investment and interest earned, upon maturity, be rolled over to the subsequent period.

For T-Bills rolled over, we used the same “Journal Entries” to pass the necessary entries so that the principal is re-invested while interest is earned on the new investment.

Additional investment in Fixed Deposit/Treasury bills

The procedure for treating investment in TBills and fixed deposit also applies to additional investment. On your report, the value of the investment should reflect the current amount invested so far.

Liquidation of existing holdings on maturity

On fixed deposits liquidated before or on maturity, we cleared the investments account with the value of the liquidation and transferred the value to the receiving bank.
