AI agents for business finance: what they can and can't do
What AI agents can do in bookkeeping, close, collections and compliance today, where a person must stay in charge, and how to judge a product.
The short answer
The Treasury Single Account pools the receipts of federal ministries, departments and agencies into one account structure at the Central Bank of Nigeria, so MDAs no longer keep their own accounts at commercial banks. It began as an initiative in 2012 and was escalated to full implementation in 2015, running on the Remita platform. For banks it meant losing cheap public deposits; the CBN still applies a separate, higher cash reserve ratio to public money held outside the TSA.
What the TSA is
Before the TSA, each federal ministry, department or agency (MDA) could hold accounts at commercial banks, collect revenue into them and keep balances there. The Treasury Single Account replaces that with one consolidated structure at the CBN. As ITEdgeNews reported from a 2017 seminar with the then Accountant-General, MDAs may not operate accounts outside the CBN, and public-sector accounts at private banks were ended. The idea is simple: the government should be able to see all its cash in one place, and not borrow at interest while its own agencies sit on idle balances elsewhere.
Why governments use one account
A single treasury account is a standard public-finance tool, not a Nigerian invention. The logic has three parts. First, cash management: if the Treasury can see every naira the government holds, it does not need to borrow to pay a bill while money lies idle in an agency's account. Second, control: spending has to pass through one gate, which makes leakages and unauthorised accounts harder to hide. Third, cost: fewer accounts means fewer bank charges. The trade-off is that agencies lose some flexibility and must wait for releases, and the system depends on the central platform working smoothly.
How money flows
- A citizen or company pays a federal fee, tax or charge through a bank or approved channel.
- The payment is routed to the relevant MDA's sub-account within the TSA at the CBN.
- The Office of the Accountant-General of the Federation sees the consolidated position and releases funds to MDAs for approved spending.
The collection system runs on Remita, software built by the Nigerian firm SystemSpecs (ITEdgeNews). When you pay a federal agency, the Remita Retrieval Reference (RRR) on your receipt is part of that system.
What it did to banks
Public-sector deposits were cheap funding for banks. When the TSA moved them to the CBN, banks lost those balances and the fees and float that came with them. The Accountant-General claimed in 2017 that the government was saving about ₦11 billion a month, over ₦132 billion a year, by avoiding overdraft interest, maintenance costs and other bank charges (ITEdgeNews, September 2017). That is the government's own estimate.
Some public money still sits outside the TSA, for example with state governments or bodies not enrolled. The CBN treats it differently: at its September 2026 Monetary Policy Committee meeting it retained a cash reserve ratio of 75% on non-TSA public-sector deposits, against 45% for ordinary deposits at commercial banks (CBN monetary policy decisions page).
| Item | Before TSA | With TSA |
|---|---|---|
| Where MDA revenue sits | Many commercial bank accounts | Sub-accounts at the CBN |
| Visibility of total cash | Fragmented | Consolidated at the Treasury |
| Bank funding from public deposits | Significant | Largely removed |
What it means for you
- Your own bank deposits are not affected; deposit insurance is covered in NDIC deposit insurance limits.
- Keep the RRR from any federal payment; it is how the payment is traced.
- For how the CBN's other tools work, see how to read a CBN circular and the CBN Act explained.
A common confusion is to think the TSA means the CBN holds everyone's money. It does not. The TSA covers federal government receipts. Private individuals and businesses keep banking with commercial banks, microfinance banks and other licensed institutions as before.
The ITEdgeNews report also recorded unresolved challenges in 2017, including some arms of government not enrolled. Current enrolment figures were not confirmed in our checks.
