Start with the security record, not the net bank credit
Retrieve the purchase confirmation and identify the security, legal holder, acquisition date, cost, face value and maturity. Agree those details with the investment ledger. TreasuryDirect explains that bills are sold at a discount or at par and pay face value at maturity. The difference between purchase cost and maturity proceeds therefore needs a clear accounting record.
This is a reconciliation of a holding the business already owns. It does not establish whether Treasury bills fit the company's investment policy or whether a particular holding is classified as a cash equivalent. Ask the accountant to review recognition and presentation under the applicable framework using the actual acquisition and maturity information.

Follow the maturity instructions through the custodian
Determine whether the bill is held directly in TreasuryDirect or through a bank or broker. Obtain the applicable maturity and settlement records. TreasuryDirect distinguishes redemption from scheduled reinvestment and directs holders using banks or brokers to those institutions for their options and processes.
Identify the destination of the proceeds and any instruction to reinvest. A maturity schedule should not assume that the full face value will enter the operating bank account when another instruction is active. Confirm the actual event with the custodian's statement and any bank receipt.
If money passes through a custody cash account before reaching the bank, reconcile both stages. Keep transfer references and dates so the accountant can explain a delay without treating the same proceeds as available in two places at once.

Separate redemption from the new purchase
For a reinvestment, retain the maturity of the old bill and the acquisition of the new bill as distinct records. The new security can have a different purchase price even when its face value matches the old one. Reconcile any cash difference, fee or other adjustment to the custodian's evidence.
A hypothetical bill purchased for $49,600 and redeemed for $50,000 has a $400 purchase-to-maturity difference before considering other facts. If the accountant has already recognized some income over the holding period, the maturity entry must settle the existing schedule rather than recognize the same amount twice. The appropriate timing depends on the reporting and tax rules that apply.
Do not infer the new investment's cost from a small net bank credit alone. The custodian's trade and reinvestment confirmations should establish the gross redemption, new acquisition and amount paid out or otherwise retained. Preserve all three in the working paper.
Close the old holding and carry forward the supported new balance
Reconcile the old security's carrying amount and recognized income with its final disposition. Agree the new holding to the acquisition confirmation and statement. Investigate any residual balance left under the matured security's identifier rather than rolling it into an unexplained investment-difference account.
Update the treasury register and cash forecast using confirmed amounts and destinations. Keep unsettled transfers visible, and confirm that the designated bank account remains open and owned by the correct entity. A bank-account change should be communicated through the custodian's authorized process before future proceeds are sent.
Provide the accountant and tax preparer with the complete holding history and any information statements issued. Book income, tax reporting and cash receipts may require a bridge. Retain the approved reconciliation so the next period begins with identifiable holdings and no duplicate maturity income.
