Stamp Duty: What It Is & Why Banks Deduct It
Stamp duty is a statutory tax charged on certain documents and electronic instruments to validate them for legal purposes, Stamp duty has existed for decades, In Nigeria the scope of stamp duties was expanded to cover electronic documents and transactions, meaning receipts, electronic transfers and other digital payment records can attract a fixed duty. The Finance Act and the Stamp Duties Act together and clarifications from tax authorities determine which electronic transactions are dutiable.
Where The Rule Comes From:
- Stamp Duties Act (Cap S8 LFN 2004) and updates (Finance Act) — these provide the statutory framework for stamp duties and were updated to explicitly include electronic instruments.
- FIRS clarifications & circulars — the Federal Inland Revenue Service (FIRS) issued guidance on stamping electronic documents and what qualifies as a dutiable instrument.
- CBN / banking circulars — the Central Bank of Nigeria and other apex banking circulars have directed banks and financial institutions on collecting certain statutory levies (including the collection and remittance mechanics for stamp duties). The CBN’s guide to bank charges sets how banks may apply fees and statutory levies in practice.
These combined instruments are why banks (and more recently some fintech) now collect a small fixed stamp duty on eligible electronic receipts or transfers.
How banks collect stamp duty (the N50 charge):Although the legal framework is about stamp duty generally, the practical, widely-seen implementation in Nigeria is the ₦50 charge applied to eligible inflows. Common operational rules banks have applied include:
- The ₦50 stamp duty is often charged on receipts or transfers equal to or above a threshold (commonly ₦10,000 in many banks’ implementations; earlier implementations used ₦1,000 in some circulars). There have been variations and clarifications over the years.
- The duty is typically debited from the receiving account (i.e., the beneficiary pays it), not the sender.
Banks remit collections to the appropriate government account following CBN/FIRS instructions and reporting procedures . NIBSS and other payment ecosystem players also track such collections when applied by fintech.
Note: The exact threshold (₦1,000 or ₦10,000) and scope have changed across circulars, bank notices and court decisions — which is why you may see slight differences between banks or fintech.
Why Banks Deduct Stamp Duty:
Revenue for government: Stamp duties are a recognized tax source. Expanding them to electronic instruments helps capture revenue from the digitalized economy. The money deducted is sent to FIRS (for corporate accounts), State IRS (for individual accounts) It contributes to Government revenue, Public services and infrastructure Some financial instruments (e.g., receipts, bank cheques)
Legal validation: CBN has issued multiple circulars directing banks to charge ₦50 on qualifying transfers, Remit immediately to the appropriate tax authority. This makes the deduction automatic in all Nigerian banks. Stamp duty historically validates documents for use in court or for official purposes — electronic receipts are now part of that regime.
Formalizing digital transactions: As more commerce moves online, consistent statutory treatment helps tax administration and record-keeping. The stamp duty is charge on Electronic transfers of ₦10,000 and above, Deposits into current or savings accounts from another bank.
How Stamp Duty Relates To Other Small Banking Charges:
The ₦50 stamp duty alongside items like SMS alert fees, card maintenance and small transaction fees (e.g., the ₦11.25 micro-charges some banks apply). These are distinct:
- Stamp duty = statutory tax (remitted to government in line with FIRS/CBN directives).
- Other small charges (SMS alerts, maintenance, service fees) = bank/commercial fees for services. See SMS Alert charges in Nigeria | How to stop them , See ATM Withdrawal Charges Explained,

How to reduce or manage stamp duty
- Consolidate inflows: fewer, larger receipts may reduce the number of times a stamp duty is applied (depending on threshold rules).
- Use same-bank transfers where possible for transfers between your own accounts (many banks exempt transfers between accounts owned by the same customer in the same bank).
- Compare banks & fintech: some fintech and banks set different thresholds or rules — shop around, and read the fee schedule before transacting. Recent fintech implementations show continued expansion of stamp duty collection across the payment ecosystem.
- Ask for clear receipts: stamp duty collections should be visible and documented on your bank statement — keep proof if you need to query a charge.
- Follow regulatory updates: thresholds/coverage can change (CBN and FIRS occasionally issue clarifications), so subscribe to your bank’s notices or the FIRS/CBN pages for updates.
Moreover; stamp duty remains one of the most misunderstood charges in Nigeria’s financial ecosystem, largely because most users perceive it simply as a recurring ₦50 debit from their bank accounts. However, stamp duty is a long-standing statutory tax, not a bank-generated fee. Its expansion into the digital space is a result of Nigeria’s evolving payment landscape, where cashless transactions, online banking, and fintech services have become the dominant channels for commerce.
Understanding stamp duty is crucial for every bank customer because it helps distinguish government taxes from bank service charges, many of which appear similar on account statements.
As Nigeria’s regulatory environment continues to develop—especially with the introduction of modern tax reforms—stamp duty will remain a major component in how the government tracks, validates, and taxes electronic receipts. For individuals and businesses, this knowledge empowers better financial planning, clearer understanding of charges, and more informed decisions when using banking platforms.
Ultimately, stamp duty is not designed to burden account holders but to ensure that every qualifying electronic receipt carries the same legal weight and compliance standard as traditional paper-based instruments. By staying updated on the rules, thresholds, and exemptions, Nigerians can avoid unnecessary deductions, reduce confusion when monitoring their bank charges, and better position themselves in a rapidly digitizing financial landscape.
