When Cryptocurrency Moves Between Wallets: How Can a Business Prove Who Owns It?

Cryptocurrency transactions can appear straightforward. A business buys digital assets, stores them in a wallet, transfers them to another wallet, and later reports the balance in its financial records.

But an important accounting and tax question can arise:

How does the business prove that the cryptocurrency in a particular wallet actually belongs to the business?

This question becomes particularly important when cryptocurrency moves between multiple wallets, exchanges, custodians, directors, employees or related entities.

The blockchain can provide a permanent record of a transaction. It can show that a particular quantity of cryptocurrency moved from one wallet address to another. However, a wallet address by itself does not necessarily identify the legal owner of the asset.

For businesses, therefore, transaction visibility and proof of ownership are not the same thing.

Understanding the Difference Between a Wallet and Its Owner

A cryptocurrency wallet is generally identified through an address or addresses. Blockchain records can show transactions involving those addresses.

For example:

Wallet A → 2 BTC → Wallet B

The blockchain may allow a reviewer to verify:

• the sending wallet;
• the receiving wallet;
• the quantity transferred;
• the transaction hash;
• the date and time of the transaction;
• and, depending on the blockchain, other transaction details.

But the blockchain record may not state:

“Wallet B belongs to ABC Limited.”

That connection must generally be supported through additional evidence.

This is why businesses holding virtual assets need controls around ownership, custody, authorisation and record keeping.

Nigeria's current tax framework specifically addresses virtual assets. The Nigeria Revenue Service's July 2026 Guidelines on the Taxation of Virtual Assets apply to persons who acquire, dispose of, exchange or otherwise deal in virtual assets. The guidelines also address registration, reporting, filing, record keeping, valuation and computation of taxable income. (National Rivers Settlement)

Why Does Proof of Ownership Matter?

Suppose a Nigerian company reports cryptocurrency worth ₦100 million as part of its assets.

Management provides a wallet address containing cryptocurrency worth approximately ₦100 million.

An important question follows:

What evidence connects that wallet to the company?

Without sufficient supporting evidence, there may be uncertainty around whether:

• the asset belongs to the company;
• the asset belongs to a director personally;
• the wallet is controlled by an employee;
• the cryptocurrency belongs to another company;
• the company merely has temporary custody of the asset;
• or the wallet contains assets belonging to several parties.

This distinction matters for financial reporting, tax compliance, internal controls and accountability.

What Evidence Can Help a Business Establish Ownership?

No single document will necessarily answer every ownership question. A business should maintain a coherent evidence trail.

1. Corporate documentation

The company should document its decision to acquire or hold cryptocurrency.

Depending on the circumstances, relevant documentation could include:

• board or management approvals;
• investment or treasury policies;
• contracts;
• accounting records;
• payment records;
• purchase documentation;
• and authorised transaction instructions.

The purpose is to establish that the acquisition was undertaken for the company rather than an individual acting in a personal capacity.

2. Exchange records

Where cryptocurrency is acquired through an exchange or other identifiable platform, the business should retain appropriate transaction records.

These may include:

• account statements;
• transaction confirmations;
• deposit records;
• withdrawal records;
• trade history;
• wallet addresses;
• and records identifying the account holder.

These records can help connect the company's identity with the movement of the digital asset.

3. Blockchain transaction records

Blockchain records can provide important evidence about what happened to the cryptocurrency.

For example:

Exchange account → Company Wallet A → Company Wallet B

The transaction hashes can help establish the movement of the asset between addresses.

However, the blockchain record should normally be considered alongside evidence establishing the company's relationship with those addresses.

4. Evidence of wallet control

Control is an important consideration.

A company should have documented procedures showing who is authorised to initiate or approve cryptocurrency transfers.

For example:

Finance Manager requests transfer → authorised officer approves → wallet transaction is executed → transaction hash is recorded → accounting records are updated.

This creates an internal control trail.

Importantly, private keys, seed phrases and passwords should not be unnecessarily disclosed to auditors, consultants or other third parties. Evidence of control should be obtained through appropriate procedures without compromising the security of the wallet.

What Happens When a Company Uses Multiple Wallets?

This is where cryptocurrency accounting can become more complicated.

A business may have:

• an exchange wallet;
• a cold wallet;
• an operational wallet;
• a treasury wallet;
• a payment wallet;
• and wallets used for specific projects.

If transfers occur between these wallets, the accounting records should make the relationship clear.

For example:

A transfer between two wallets controlled by the same company may represent movement of custody rather than a disposal of the cryptocurrency.

But the accounting and tax treatment depends on the facts and the applicable tax rules. The transaction should therefore be properly documented rather than automatically treated as a taxable disposal or an ordinary expense.

Cryptocurrency Transfers Can Create a Hidden Accounting Problem

Consider this example.

ABC Limited purchases cryptocurrency for ₦50 million.

It records:

Cryptocurrency asset — ₦50 million

The company then transfers the cryptocurrency from Wallet A to Wallet B.

The finance team records another ₦50 million cryptocurrency purchase because the new wallet now contains the asset.

The company's records could then incorrectly show:

Wallet A — ₦50 million
Wallet B — ₦50 million
Total — ₦100 million

when the company actually owns only ₦50 million of cryptocurrency.

This is why wallet-to-wallet reconciliation matters.

The accounting system should distinguish between:

Acquisition

and

Internal transfer.

What Should a Cryptocurrency Reconciliation Contain?

A business can maintain a cryptocurrency reconciliation showing:

1. Opening wallet balance;
2. Purchases;
3. Sales;
4. Transfers in;
5. Transfers out;
6. Mining or staking receipts where applicable;
7. Other receipts;
8. Fees;
9. Closing wallet balance;
10. Blockchain transaction hashes;
11. Exchange records;
12. Accounting ledger balance.

This creates a bridge between the blockchain record and the company's accounting records.

How Does This Connect With Nigerian Tax Compliance?

This is particularly relevant because Nigeria's current tax administration framework contains specific provisions concerning virtual assets.

The Nigeria Tax Administration Act 2025 provides for a virtual-assets framework covering activities including exchange, trading, custody and issuance. It also identifies taxable virtual-asset transactions including the sale, exchange or transfer of virtual assets, mining or staking activities that generate income, and certain airdrops, bounties or virtual assets received as compensation or reward. (National Rivers Settlement)

The Act also provides that taxable persons engaged in virtual-asset activities are required to keep books and records and report virtual-asset activities to the relevant tax authorities. (National Rivers Settlement)

The NRS's 2026 Guidelines further provide administrative guidance on valuation, computation, reporting and record keeping for virtual-asset activities. (National Rivers Settlement)

Therefore, a business should not treat cryptocurrency records as something separate from its wider tax records.

Why Proper Tax Filing Matters for Businesses

Tax compliance is not simply about making a payment.

A compliant tax process involves:

Identification → Record keeping → Classification → Computation → Filing → Payment → Documentation → Reconciliation

Errors can occur when a business:

• fails to identify a taxable transaction;
• records the wrong transaction date;
• uses incomplete exchange records;
• fails to reconcile wallet movements;
• confuses personal and business transactions;
• omits relevant cryptocurrency income;
• incorrectly classifies transfers;
• or cannot substantiate figures reported in its tax return.

For businesses with significant or complex cryptocurrency activity, engaging a qualified professional tax or accounting adviser can provide an additional layer of review over transaction classification, records, reconciliations, tax computations and filing.

That does not transfer the taxpayer's legal responsibility for accurate information. Management remains responsible for the completeness and accuracy of the records and information provided.

Why Businesses Should Comply With Tax Regulations

Tax compliance supports several important business objectives.

1. It creates reliable financial records

A business that properly records its cryptocurrency transactions is better positioned to understand what it owns, what it has disposed of and what it owes.

2. It supports accountability

Clear records allow management, shareholders and other authorised stakeholders to understand how company assets are being used.

3. It supports regulatory reporting

Proper records provide a basis for preparing accurate tax and other statutory filings.

4. It reduces avoidable disputes

When transactions are properly documented, the business has evidence to explain the figures reported in its accounts and returns.

5. It improves internal control

Cryptocurrency can move rapidly. Documented approval and reconciliation procedures can help reduce unauthorised transactions and accounting errors.

Tax Credits, Incentives and Opportunities: What Should Businesses Consider?

Businesses should distinguish between legitimate tax reliefs or incentives provided by law and informal ideas about "reducing tax."

The NRS maintains information on applicable incentives and exemptions, and businesses should determine eligibility based on the specific legislation and conditions applicable to them. (National Rivers Settlement)

For a cryptocurrency-related business, relevant areas to review may include:

• allowable deductions where applicable;
• capital allowances where relevant to the underlying business activity;
• available tax incentives applicable to the business sector;
• treatment of qualifying business expenditure;
• withholding-tax implications where applicable;
• tax treatment of income generated from digital-asset activities;
• and available reliefs or exemptions under the applicable tax legislation.

The key principle is simple:

A tax opportunity should be based on a provision of law and supported by appropriate records.

A business should not create artificial transactions simply to obtain a perceived tax advantage.

Practical Steps Nigerian Businesses Can Take

If your company holds or transacts in cryptocurrency, consider implementing these controls:

Keep a wallet register

Record every wallet used by the business and its purpose.

Separate personal and corporate wallets

Do not casually mix directors' personal cryptocurrency with company assets.

Record every transaction hash

A transaction hash can provide a useful reference for tracing a blockchain transaction.

Maintain exchange statements

Do not rely solely on screenshots.

Reconcile regularly

Compare blockchain balances, exchange balances and accounting records.

Document approvals

Significant cryptocurrency transactions should follow the company's approval procedures.

Record the purpose of transfers

A transfer to another wallet should have an identifiable business explanation.

Maintain valuation records

Document the basis used to determine the value reported for accounting and tax purposes. Nigeria's tax administration legislation provides for valuation of virtual assets using the prevailing market price at the time of the transaction, based on a recognised virtual-asset exchange platform approved by the Service. (National Rivers Settlement)

Review tax treatment before filing

Different types of cryptocurrency activity can have different tax consequences. Do not assume that every wallet movement has the same treatment.

The Role of Professional Tax and Accounting Support

Cryptocurrency introduces an additional layer of complexity into ordinary financial record keeping.

A professional consulting firm can assist a business with areas such as:

• reviewing cryptocurrency transaction records;
• reconciling wallets and exchange accounts;
• identifying missing documentation;
• assisting with tax computations;
• reviewing the classification of transactions;
• supporting tax return preparation;
• maintaining appropriate working papers;
• and helping management understand its record-keeping obligations.

For a business using a professional firm, the objective should not simply be to "file taxes." The broader objective is to establish a defensible trail from the underlying transaction to the accounting records and ultimately to the tax return.

That distinction is important.

A Simple Ownership Evidence Framework

A useful way for management to think about cryptocurrency ownership is:

TRANSACTION → WALLET → CONTROL → BUSINESS RECORD → TAX RECORD

Ask five questions:

1. What happened?
Can the transaction be verified?

2. Which wallet was involved?
Can the blockchain address be identified?

3. Who controls the wallet?
Is there evidence connecting the wallet to the company?

4. How was it recorded?
Does the accounting system accurately reflect the transaction?

5. How was it treated for tax purposes?
Has the applicable Nigerian tax treatment been considered?

If these five questions can be answered with appropriate evidence, the business has a stronger basis for demonstrating how its cryptocurrency activity was recorded and reported.

Final Thoughts

Cryptocurrency may operate on decentralised networks, but business accountability still requires identifiable records, controls and evidence.

A blockchain transaction can show that cryptocurrency moved between addresses. The more difficult question for a business may be establishing whose asset it is, who controls it, why it was transferred, how it was recorded and what tax consequences arise.

For Nigerian businesses, this is increasingly relevant as the country's tax framework now contains specific provisions and administrative guidance concerning virtual assets. (National Rivers Settlement)

The practical lesson is therefore straightforward:

Do not let the transparency of blockchain transactions create a false sense that the accounting evidence is complete.

A transaction can be visible on-chain while the business's ownership documentation remains incomplete.

Frequently Asked Questions

1. Does a blockchain prove who owns a cryptocurrency wallet?

Not necessarily. Blockchain records can establish transactions involving a wallet address, but additional evidence may be needed to connect that address with a particular individual or company.

2. Can a company have more than one cryptocurrency wallet?

Yes. A company may use different wallets for different purposes. The important consideration is maintaining appropriate records identifying the wallets, their purpose and the company's control over them.

3. Is transferring cryptocurrency between two company wallets automatically a taxable sale?

Not necessarily. The tax treatment depends on the facts and the applicable Nigerian tax provisions. An internal movement of an asset should not automatically be treated as a sale simply because the cryptocurrency changed wallet addresses.

4. What records should a cryptocurrency business keep?

Relevant records may include exchange statements, wallet addresses, transaction hashes, purchase and disposal records, payment records, valuation information, approvals and accounting records.

5. Can cryptocurrency transactions be audited?

Yes. Blockchain records can provide useful transaction evidence. However, other procedures and supporting documentation may be required to establish ownership, control, completeness, valuation and the appropriate accounting treatment.

6. Does Nigeria have specific tax rules for virtual assets?

Yes. Nigeria's current tax administration framework contains provisions concerning virtual assets, and the NRS published Guidelines on the Taxation of Virtual Assets on 31 July 2026. (National Rivers Settlement)

7. Should cryptocurrency transactions be included in business records?

Where cryptocurrency transactions relate to the business, they should be appropriately recorded and supported by relevant documentation. The exact accounting and tax treatment depends on the nature of the transaction and the applicable rules.

8. Should a business use a professional tax consultant for cryptocurrency transactions?

A business can prepare its own tax affairs where permitted, but cryptocurrency transactions can involve complex classification, valuation, reconciliation and record-keeping issues. Professional assistance can be useful where the transactions are numerous, material or complex.

9. What is the most important cryptocurrency control for a business?

There is no single control that addresses every risk. A combination of authorisation, wallet identification, access controls, transaction records, reconciliation and independent review provides a more structured control environment.

10. Where can a business verify its current Nigerian tax obligations?

The Nigeria Revenue Service provides taxpayer self-service facilities covering tax filing, payments, assessments, tax clearance and other tax administration functions. (NRS Self Service)
