Tax Considerations

In this article, we’ll discuss basic tax law around payments, establish an analogy between OP_CHECKTEMPLATEVERIFY and traditional certified cheques, and then discuss the relevant tax consequences.

In the “legacy” financial world, a cheque1 is commonly used to move funds from financial institutions in lieu of inconvenient physical cash transfers. To date, Bitcoin has not needed the concept of a cheque because Bitcoin transactions are direct transfers with no intermediary, i.e., as cash is to a cheque.

The introduction of OP_CHECKTEMPLATEVERIFY enables a new kind of payment on Bitcoin that more closely resembles a cheque than a cash transfer. Any new form of payment may have differences in tax treatment.

To start, what is a cheque, exactly? A cheque is an endorsed instrument instructing a bank to transfer funds from one account to a recipient. A cheque has a few critical pieces of information:

  • An account number
  • An issuing bank or & drawee (by Bank ID)
  • A signature from the account holder
  • An amount of money
  • A recipient or payee (by name)
  • A date on which the cheque is made (and thereafter redeemable, if post-dated)

The cheque, once written, is then presented to the drawee bank by the payee (or by the payee’s bank) at some arbitrary later time where it is redeemed for the amount of money specified2.

Generally, the form of payment - money, cheque, or property - is irrelevant for cash basis taxpayers3. Notice 2014-21 provides that bitcoin is property4, and it also states, regarding employment taxes, that, "[g]enerally, the medium in which remuneration for services is paid is immaterial to the determination of whether the remuneration constitutes wages for employment tax purposes." While the medium of payment is generally immaterial, a deduction is only allowed for the taxable year in which the amount is actually paid. A taxpayer on the cash method of accounting cannot deduct an amount by issuing a promissory note5. A promissory note is simply a promise to pay cash rather than a payment of cash6. Furthermore, while cash basis taxpayers are subject to the doctrine of constructive receipt of income, the corollary doctrine for deductions - i.e., constructive payment - is not recognized for federal income tax purposes.

While the above makes clear that it doesn’t matter if we’re using a cheque or Bitcoin for a payment, it’s worthwhile to compare the form of the payment contract in Bitcoin to that of a cheque.

In a traditional Bitcoin transaction, the constituent parts are the same as a cheque. What differs is that there is no asynchronous “at some arbitrary later time” redemption step required by the bitcoin recipient to receive the funds - assuming no time lock, bitcoin is treated as sent and received at the same time for tax purposes.

You could emulate this asynchronous step in Bitcoin by sending to a user a “pre-signed” transaction which has not yet been broadcast to the Bitcoin network. Then, when the user wants the funds, they could broadcast the transaction to the network. Functionally, this would be almost identical to a cheque. The issue with this technique is that it’s possible for the funds sent in such a cheque to be “double-spent”, that is, for the accounts to be insolvent against the obligation and the cheque bounces.

As noted above, bank accounts may have insufficient funds in an account to redeem a cheque. To address the issue of insufficient funds for traditional cheques, banks introduced a notion of a “certified” cheque. In a certified cheque, the bank attests to the solvency of the account and guarantees sufficient funds when redeemed when the cheque is written. As un-certified cheques are already treated as actual-cash, the legal distinction between a certified and uncertified cheque is irrelevant for this document. Given the difficulties in catching and enforcing the law against writers of fraudulent cheques, it is important to make clear that we are analogizing to the less fraught certified cheque.

A transaction making use of OP_CHECKTEMPLATEVERIFY is a direct analog for a certified cheque. When using OP_CHECKTEMPLATEVERIFY, first a sender creates (but does not sign & broadcast) a collective root transaction paying multiple recipients, and branches to individualized leaf outputs. Next, the sender must communicate all parts of the tree of transaction data needed by the recipient to claim their bitcoin, or else they may not have sufficient information to ensure the payment. The sender could collect digital signatures from the recipient for receipt of the transaction tree data before making the payment, or use standard email notification agreements. Exchange of such signatures can happen automatically in application code without user interaction. This notice requirement is not unique to payments made using OP_CHECKTEMPLATEVERIFY, any Bitcoin transaction may require such notice. This is similar to a certified cheque, which much be transferred physically to the recipient (and unlike a wire, which is received automatically). Then, the sender signs and broadcasts the transaction.

Similar to regular Bitcoin transactions, receipt is guaranteed after a reasonable number of confirmations on the root transaction; however, recipients may individually defer creating the outputs until fees are lower. At this point, recipients are in constructive receipt of income at this point (because actual receipt is at their option), while sender will have a current deduction. This is equivalent to issuing a certified cheque and redeeming it later. Typically, a Bitcoin transaction making use of OP_CHECKTEMPLATEVERIFY would be immediately spendable by the recipient if the recipient were willing to pay the current market price for transaction fees. As such, it would be considered paid by the sender, and actually (or constructively) received by its recipients after a reasonable number of confirmations.

Thus, we’ve established a strong analogy matching cheques and Bitcoin payments made using OP_CHECKTEMPLATEVERIFY. This establishes an intuitive and common sense treatment of OP_CHECKTEMPLATEVERIFY payments which is in accordance with long standing precedent for payments by cheque such as Estate of Modie J. Spiegel v. Commisisoners7. Simply put, OP_CHECKTEMPLATEVERIFY works just like you would expect it to.

  6. A promissory note is differentiated from a cheque as a cheque is considered actual cash, i.e., a bounced cheque can be considered criminal fraud similar to using counterfeit bills, whereas failure to pay a promissory note could be considered only a breach of an agreement (contractually binding or not). ↩︎

  7. It is well established that a check constitutes payment by a cash basis taxpayer. See Spiegel’s Estate v. CIR, 12 TC 524 (1949) (acq.). Rev. Rul. 54-465, 1954-2 CB 93 (holding “[a] charitable contribution in the form of a check is deductible in the taxable year in which the check is delivered provided the check is honored and paid and there are no restrictions as to time and manner of payment thereof.").

    Because a certified cheque is guaranteed to be honored and paid, we may also ignore this distinction when considering a OP_CHECKTEMPLATEVERIFY certified cheque.

    The only consideration to make is if there are additional restrictions as to the time and manner of payment. It is possible to post-date a cheque using OP_CHECKTEMPLATEVERIFY, which would delay payment as well as the time when a recipient could access their funds8.

    For now, let’s assume that no additional encumbrance is placed on a OP_CHECKTEMPLATEVERIFY transaction9. In such a case, the sender can consider the funds as paid as soon as the transaction is confirmed. The sender may also use this time for computing their gains and losses from the transaction.

    Moreover, the day following the day that a root transaction is confirmed is the date on which the recipient’s holding period begins10, even if the individual UTXO is not redeemed until later. ↩︎

  9. When time locks get involved, the tax issues become less certain. While lock times are not a unique feature of OP_CHECKTEMPLATEVERIFY transactions, the congestion control motivation makes it likely that the features will be used together in common practice. In principle, the correct application of timelocks and contractual agreements could allow a sender and recipient to optimize for purposes of taxable income and loss realization.

    A Bitcoin transaction which is subject to a time lock specified by the sender may be deductible at the time it is confirmed, or it may constitute a prepayment. Generally, the determination is made by applying the three-pronged test for deductibility provided by Rev. Rul. 79-22911. The outcome in applying the three-pronged test to a time locked payment is highly fact dependent; generally, the ruling provides that expenditures for prepaid amounts are allowable if:

    1. the expenditure represented a real “payment” and not a deposit;
    2. the prepayment was made for a business purpose “and not merely for tax avoidance;” and
    3. there was no “material distortion of income.”

    The IRS identified as factors “indicative of a deposit” a contract calling for an indefinite quantity, a right to refund, or a right to substitute other products.

    Thus, a bitcoin transaction subject to a time lock may be deductible if it is not a deposit, it is made with a business purpose, and it does not materially distort the income of the sender; however, a significant transaction that is treated by its sender as paid in a taxable year preceding the taxable year(s) in which the time lock expires may be challenged by the IRS. ↩︎
