OPINION
Shields, Judge-.
Each party has filed a motion for partial summary judgment with respect to the following issues:
(1) Whether or not a nonrecourse obligation undertaken by the petitioner in 1978 is too contingent to be treated as a bona fide indebtedness for tax purposes.
(2) Whether or not petitioner is at risk, under section 465,1 respecting an amount received in 1979 from the purported sale of an option.
(3) Whether or not the purported option granted in 1979 is to be treated as a true option for tax purposes.
The parties have filed under Rule 121,2 affidavits in support of their respective motions. For our consideration, they have also filed joint exhibits which contain not only the petitioners’ income tax returns for 1978 and 1979 but also the promotional materials leading to the transactions in dispute as well as the legal documents underlying such transactions.
In their motions and in oral argument, the parties have agreed that, for present purposes, we may assume the various steps of the transactions in dispute were consummated in the manner set out in the stipulated documents. Consequently, no material fact appears to be in dispute and the motions appear to be in order.
For 1978 and 1979, Ernest J. Saviano and Margaret Saviano, husband and wife, filed joint income tax returns using the cash basis of accounting. At the time their petition was filed they resided in Wisconsin. Margaret Saviano is a party solely because she filed joint returns with her husband. Consequently, as used hereinafter, the word "petitioner” shall refer only to Ernest J. Saviano.
During both years, the petitioner, an airline pilot, was furnished with promotional packages by International Monetary Exchange (hereinafter referred to as IME), a Panamanian corporation. The packages touted the tax advantages to be obtained by the petitioner and other high-bracket taxpayers through "investments”3 in a leveraged tax shelter known as "Gold For Tax Dollars.” Although a different shelter was promoted for each year, basically the two shelters were the same in the sense that both were designed to secure for the petitioner a tax deduction for an expense in the current year which was at least 4 times greater than the amount of his cash outlay. Technically, however, the shelters differed because the 1978 package contemplated the payment of a substantial portion of the deductible expense from the nontaxable proceeds of a nonrecourse loan, while in 1979, a substantial portion of the payment was to be made with the proceeds from the sale of an option which would be taxable in a subsequent year when the option was either exercised or was permitted to lapse.
The petitioner followed the instructions furnished by IME, made his "investment” in both years, claimed the suggested deductions on his tax returns, was subsequently advised by the respondent that the deductions were disallowed, and together with his wife, timely filed a petition with this Court.
The 1978 Transaction
At some point in 1978, the petitioner learned of a gold mining venture in Panama which was being promoted as a tax shelter throughout the United States by IME under the name of "Gold For Tax Dollars.”4 The promotional materials distributed by IME offered high-salaried taxpayers, such as the petitioner, a means of sheltering their otherwise taxable income from Federal income tax on a ratio of 4 to 1. In other words, the petitioner was told by IME that for each $1 of cash he invested in the shelter in 1978, he could deduct $4 from his gross income.5
The plan outlined in the promotional materials contemplated that a taxpayer would authorize IME as his agent to acquire a mineral lease or claim on certain gold-bearing land located in Panama. The taxpayer would then deposit with IME cash equal to one-fourth of the amount of the deduction he desired for 1978, and would borrow from IME the other three-fourths on a nonrecourse obligation which would bear interest at 10 percent but which would be payable from and secured only by the taxpayer’s mineral claim. As the taxpayer’s agent, IME would then, during 1978, pay over the entire sum (the one-fourth deposited by the taxpayer, plus the three-fourths represented by the nonrecourse obligation) to a mining contractor for preparing the claim for extraction of the gold. IME’s materials, including a tax-opinion letter,6 assured the taxpayer that by the adoption of the above procedure, he could become a miner in 1978. As such, he would be entitled to deduct under section 616(a) as mine development expense the entire sum paid to the mining contractor, i.e., both his deposit plus the proceeds of the nonrecourse loan.
The petitioner, following the instructions of IME, proceeded with respect to 1978 as follows:
(1) He deposited $10,000 with IME after determining that 4 times that amount or $40,000 was the amount of the deduction he needed in 1978.7
(2) He obtained through IME a mineral claim on 25,000 cubic meters of gold-bearing land. He determined the number of cubic meters to be included in the claim by following IME’s instructions to divide the desired deduction ($40,000) by the $1.60 per cubic meter to be paid the mining contractor.
(3) He and IME executed a document entitled "Mineral Loan Agreement” under which IME, as lender, agreed to advance to him, as miner, up to 75 percent of the estimated market value of the minerals located in his mineral lease. Any advances under the agreement were to bear interest at 10 percent per annum and were to be secured by a general lien in favor of IME upon all sales, accounts, or other proceeds resulting from his mineral claim or any minerals extracted therefrom. Under the agreement, IME was also entitled to a commission of 2 percent of the net amount of any sales made from the claim. The only security for the payment of any advance, interest, or commission due under the agreement was IME’s general lien.
(4) He received through IME an advance of $30,000 under the above agreement.
(5) By his agent, IME, he paid $40,000 (his $10,000 deposit plus the $30,000 represented by the above advance) to a mining contractor to "prepare the claim to extraction.”
(6) On his joint return for 1978, the petitioner claimed a deduction for the $40,000 as mine development expense. He also claimed a refund of $15,865 from the $17,478 in income taxes which had been withheld from his salary as an airline pilot.
Section 616(a) provides for the current deduction of mine development expenses incurred after the existence of minerals in commercially marketable quantities has been demonstrated. For purposes of this motion, the parties agree that such quantities of gold existed in petitioner’s mineral claim.8
The question we must decide is whether IME’s $30,000 loan to petitioner was too contingent by its terms to constitute a valid obligation for which petitioner might claim a deductible payment.
The respondent argues that under the very terms of the mineral loan agreement, the repayment of the $30,000 is too contingent to be recognized for tax purposes. He further argues that this contingency must be considered in determining whether or not the petitioner actually paid this part of the development expense claimed in 1978. It is not enough merely to accept the fact that payment was made with borrowed funds; rather, we must examine the nature of the obligation underlying the payment. Respondent concludes that no payment of the $30,000 was made. Hence, the deduction is not allowable to that extent.
For his part, the petitioner first frames the issue as being one of pure tax accounting. He argues that the source of the funds, and any condition or contingency associated with the source of the funds or their repayment, is not relevant in this case. According to his argument, all he needs to establish as a cash basis taxpayer is that during 1978, a payment was made by him or on his behalf even though such payment was made with funds that were "begged, borrowed or stolen.”
In the alternative, petitioner argues that if contingency is relevant to our inquiry on this issue, the repayment of the advance is not so uncertain as to destroy its validity for tax purposes.
We agree with the respondent that the petitioner has erroneously concluded that a payment for tax purposes is established merely by proof that money or other property has changed hands. The situations are too numerous to mention wherein this Court, in tax cases, and other courts, in many different areas, have examined all facets of a transaction in order to determine whether or not the parties have actually accomplished what they recited. To refrain, in cases of this nature, from looking at the underlying debt would require us to blindly examine each part of a transaction without considering the interrelation of each part to each other part or to the whole. Carried to its logical conclusion, the adoption of petitioner’s argument in a future case could lead us to conclude that the exchange of funds recited in one part of a transaction constituted a payment when another part of the same transaction clearly provided for the repayment of the funds.
For these motions the parties agree that IME paid $40,000 to a mining contractor in 1978. They also agree that the entire payment would constitute a mine development expense, properly deductible under section 616(a), if, for tax purposes, the payment was made by the petitioner.
For the petitioner, a cash basis taxpayer, an allowable expense is deductible only in the year in which payment is made. Helvering v. Price, 309 U.S. 409 (1940). The word "payment” has a particular meaning in the tax law. Payment occurs only when a taxpayer’s money is "irretrievably out of pocket.” Keller v. Commissioner, 79 T.C. 7, 36 (1982), quoting Ernst v. Commissioner, 32 T.C. 181, 186 (1959). In general, if a taxpayer pays an expense with funds borrowed from a third party, the expense is deductible when paid, not later when the loan is repaid. McAdams v. Commissioner, 198 F.2d 54 (5th Cir. 1952); Crain v. Commissioner, 75 F.2d 962 (8th Cir. 1935); Granan v. Commissioner, 55 T.C. 753 (1971). But a contingent future obligation of a cash basis taxpayer is not deductible until the debt is actually paid. Cavanaugh v. Commissioner, 2 B.T.A. 268, 272 (1925).
In the application of these general principles, it has been repeatedly held that if a payment is contingent upon some future event, such payment cannot be recognized. Brountas v. Commissioner, 692 F.2d 152 (1st Cir. 1982), and CRC Corp. v. Commissioner, 693 F.2d 281 (3d Cir. 1982), vacating and remanding on different grounds 73 T.C. 491 (1979); Gibson Products Co. v. United States, 637 F.2d 1041 (5th Cir. 1981), affg. 460 F. Supp. 1109 (N.D. Tex. 1978); Denver & Rio Grande Western R.R. Co. v. United States, 205 Ct. Cl. 597, 505 F.2d 1266 (1974); Lemery v. Commissioner, 52 T.C. 367 (1966), affd. on another issue 451 F.2d 173 (9th Cir. 1971); Columbus & Greenville Railway Co. v. Commissioner, 42 T.C. 834 (1964), affd. per curiam 358 F.2d 294 (5th Cir. 1966); Albany Car Wheel Co. v. Commissioner, 40 T.C. 831 (1963), affd. per curiam 333 F.2d 653 (2d Cir. 1964); Redford v. Commissioner, 28 T.C. 773, 777 (1957); Sunburst Oil & Refining Co. v. Commissioner, 23 B.T.A. 829 (1931).
In Sunburst Oil & Refining Co. v. Commissioner, a taxpayer’s liability for expenses of drilling oil and gas wells was contingent and held not accruable since payment was to be made solely from the taxpayer’s share of production from the drilled wells. Although the liability was fixed in amount, it would occur only "if and when sufficient oil was produced from the wells to pay it.” 23 B.T.A. at 836.
Sunburst Oil differs from the instant case in that it concerned a deduction of an accrual basis taxpayer whereas Mr. Saviano reports his income and disbursements on the cash method of accounting. Nevertheless, we do not believe this distinction to be controlling. An obligation so indefinite that it may not be accrued similarly may not be expensed. The loan agreement herein makes clear that repayment is conditioned on the sale of gold from petitioner’s claim. IME will be repaid only if and when sufficient gold is produced from the mine and sold.
More recently, the First, Third, and Fifth Circuits have ruled that an obligation, repayment of which was contingent upon future production of oil and gas, could not be accrued and deducted in the year that the amount of the liability became fixed. Brountas v. Commissioner, supra; CRC Corp. v. Commissioner, supra; and Gibson Products Co. v. United States, supra.
Those cases concerned limited partnership drilling ventures which bought participations in certain oil and gas leaseholds. The partnerships then contracted with the driller-operator of the leaseholds to drill exploratory wells. They paid 40 percent of the drilling costs in cash and gave nonrecourse notes for the remaining 60 percent. Although the notes were secured by the leaseholds, as a practical matter repayment would occur only if oil were produced from the wells. There, as here, repayment was contingent upon the occurrence of a future event.
All three circuits held that the noncash portion of the drilling costs was not accruable by the partnerships or deductible by the limited partners. They held that the nonrec-ourse notes were too speculative to constitute bona fide liability, reasoning that "all events” necessary to fix the fact of liability had not occurred in the year the deductions were taken.9
We realize that some of the cited cases involved contingent future payments which were claimed by taxpayers on the accrual basis of accounting. Others involved attempts by taxpayers to add contingent future payments to the basis of assets for depreciation or some other amortizable purpose. We believe, however, that the underlying principles are applicable with equal force here. In other words, an item of expense which, under the terms of a document underlying the transaction, is too contingent for accrual purposes is obviously too uncertain to constitute a payment for cash purposes. Furthermore, a liability which, under similar circumstances, is too contingent to be allowed as a portion of a taxpayer’s basis in an asset, because it is dependent in whole or in part upon a future event, would also be too contingent to be allowed as a cash deduction.
In this case, the petitioner is not personally liable for the repayment of the advanced funds. No term in the loan agreement requires him to pay his debt to IME nor does any term in the mineral lease or loan agreement require him to extract any gold or sell any gold which is extracted, both of which are conditions precedent to the payment of the advance.10
Moreover, the promotional literature in this case does not emphasize the soundness of the petitioner’s investment nor discuss the activity which would be associated with the mining venture. For example, there is no discussion of the costs associated with production or who will bear them. In fact, practically all of the discussion and emphasis is on sheltering income from taxation with scant attention given to the problems and processes of extracting gold or selling the same.
It is clear that a cash basis taxpayer cannot deduct an expense incurred unless it has been paid during the taxable year. Section 1.461-l(a)(l), Income Tax Regs. The crucial question raised here is whether the nonrecourse obligation running from petitioner to his agent, IME, constituted payment of the development expense by petitioner so as to create a deductible expense in the year the note was executed. "[U]ntil a cash basis taxpayer suffers an economic detriment, i.e., an actual depletion of his property, he has not made a payment which will give rise to an expense deduction.” Rife v. Commissioner, 356 F.2d 883, 889 (5th Cir. 1966), revg. 41 T.C. 732 (1964); see also Jergens v. Commissioner, 17 T.C. 806, 809 (1951).
This principle is analogous to that enunciated in Helvering v. Price, 309 U.S. 409 (1940), that a cash basis taxpayer’s expenditures paid with a promissory note may not be deducted until the note is satisfied. Eckert v. Burnet, 283 U.S. 140 (1931). This is because if the note is never paid, the taxpayer will have given up nothing except his promise to pay. Don E. Williams Co. v. Commissioner, 429 U.S. 569, 578 (1977); Hart v. Commissioner, 54 F.2d 848, 852 (1st Cir. 1932). Similarly, an accrual basis taxpayer would not be permitted to deduct the amount of the note until the liability becomes certain. Gibson Products v. United States, supra. See also Graf v. Commissioner, 80 T.C. 944 (1983), decided this day, wherein cash basis taxpayers attempted unsuccessfully to deduct amounts paid to a dredging subcontractor which were borrowed from IME, an independent third party, in the form of a promissory note repayable only out of profits from the sale of oceanfront lots created by the dredging operation.
We conclude that with respect to petitioner’s $30,000 "advance” from IME, petitioner did nothing more than attempt to create an artificial tax benefit. Consideration of the documentation alone clearly establishes that no actual obligation was intended or created and no economic detriment suffered for which a deduction can be allowed under section 616(a) or any other section.11
The 1979 Transaction
In 1979, IME offered the petitioner and other similarly situated taxpayers a slightly different tax shelter. Once again, IME’s promotional materials touted a 4 for 1 tax writeoff, but this time the gold-bearing land12 was located in French Guiana and the plan was based in part on the sale of an "option”13 rather than the nonrecourse loan which was used in 1978. The change from the nonrecourse loan in 1978 to the option in 1979 was admittedly made by IME because a change in the law had specifically eliminated the use of nonrecourse loans for years after 1978.14
According to the plan outlined in the 1979 materials, the petitioner could qualify for the 4 for 1 tax writeoff by authorizing IME as his agent to acquire a mineral claim on certain gold-bearing land located in French Guiana. The petitioner would then deposit with IME cash equal to one-fourth of the amount of the deduction which he desired in 1979. Acting through IME as his agent, he would sell, for cash, an option to buy the gold extracted from the claim for an amount equal to the other three-fourths of the desired deduction. As in 1978, IME would then pay a mining contractor the entire sum (the one-fourth deposited by the petitioner plus the three-fourths received from the option) for preparing the claim for extraction of the gold.
In 1979, IME again assured the petitioner both in its own materials as well as in the accompanying opinion letter15 that if he carefully followed the instructions provided, he would qualify as a miner and would be entitled to deduct under section 616(a) the entire sum paid to the mining contractor as a mine development expense. He was also assured that he would not be subject to tax on the proceeds received on the sale of the option until in some later year when the option either lapsed or was exercised.
The option could be exercised only after the commencement of production. As in 1978, petitioner was not required under the terms of the mineral claim or the option to extract any gold.
Again following the instructions furnished by IME, the petitioner proceeded as follows:
(1) He deposited $8,000 with IME.
(2) He obtained through IME a mineral claim on 20,000 cubic meters of gold-bearing land. He determined the number of cubic meters to be covered by the claim by following IME’s instructions to divide the desired deduction ($40,000) by the $2 per cubic meter which had to be paid to the mining contractor.
(3) He sold through IME an option to purchase any gold extracted from his claim for $32,000.
(4) IME, as his agent, paid $40,000 (the petitioner’s $8,000 deposit plus the $32,000 received for the option)16 to a mining contractor to prepare the claim for the extraction of gold.
(5) On his 1979 joint income tax return, the petitioner claimed a $40,000 deduction as mine development expense. He also claimed a refund of $15,667 of the $19,914 in income taxes which had been withheld from his salary as an airline pilot. He did not report as income the $32,000 he received in 1979 for the option.
Respondent argues that petitioner’s deduction should be denied to the extent of the $32,000 obtained from the sale of the option. He further argues that the option proceeds should be taxed in 1979 rather than deferred to a later year. He advances three grounds in support of his position: (a) The option transaction is the economic equivalent of a nonrecourse loan, governed by section 465 and regarding which petitioner should not be considered "at risk”; (b) the arrangement was not an option but was in reality a sale of minerals in place based upon a formula for the division of the mining proceeds, and consequently, the proceeds did not qualify for tax deferral in 1979; and (c) the arrangement was not a true option, the proceeds of which would qualify for tax deferral, but was a contractual right of first refusal or preferential treatment, the proceeds of which should be taxed in 1979.
For his part, petitioner denies that section 465 governs the transaction; denies that the optionholder acquired an economic interest in his mining claim; and asserts that the arrangement created a binding, legal option, the income from which should not be recognized until the option is exercised or lapses.
In weighing the arguments of the parties, we have carefully considered all the documents submitted in connection with the 1979 transaction — the promotional materials, the authorization agreement, the mineral claim lease, and the option.17 Because we decide for respondent on the basis of his third contention, we need not reach his other arguments.
Section 451(a) provides that an item of income shall be included in gross income in the taxable year in which received by the taxpayer unless the taxpayer’s method of accounting would provide for recognition in a different taxable year. A cash basis taxpayer must include items of income in gross income in the year actually or constructively received. Sec. 1.451-1, Income Tax Regs.
The petitioner points out that one exception to these longstanding rules of recognition is that when it cannot be determined whether payments received will, at some future date, represent income or a return of capital, then they are not taxed until their character becomes fixed. Burnet v. Logan, 283 U.S. 404 (1931); Dill Co. v. Commissioner, 33 T.C. 196 (1959), affd. 294 F.2d 291 (3d Cir. 1961); Virginia Iron, Coal & Coke Co. v. Commissioner, 37 B.T.A. 195 (1938), affd. 99 F.2d 919 (4th Cir. 1938), cert. denied 307 U.S. 630 (1939).
Petitioner then argues that the proceeds received in 1979 from the sale of the option to purchase gold are not taxable until the option is exercised or lapses. He admits that the income will eventually be taxed at ordinary rates but contends that the cost of goods sold may affect the amount of taxable income to be reported, so that deferral is proper.
Respondent agrees that binding legal options are not taxed currently.18 But he contends that no such option exists here. He maintains that IME merely labeled the 1979 transaction an option in order to invoke the principle of deferral. He points to the fact that contrary to the usual provision, the petitioner, even though grantor of the option, is actually the party with a choice. If the petitioner decides not to mine gold, the option-holder will never have the opportunity to purchase it. The respondent concludes, therefore, that this condition precedent to the exercise of the option negates the option’s validity for tax purposes and requires the proceeds to be recognized currently.
For support, the respondent relies on Saunders v. United States, 450 F.2d 1047 (9th Cir. 1971). In Saunders the taxpayer obtained a "special option” to purchase real estate. The agreement provided, however, that the grantors could repurchase the option at any time prior to its exercise. When Saunders gave notice of an intention to exercise the option, the owners promptly repurchased it. Saunders treated the amount he received on the repurchase as capital gain. The Federal District Court agreed. Saunders v. United States, 294 F. Supp. 1276 (D. Hawaii 1968). The Ninth Circuit reversed the District Court and held the gain reportable currently as ordinary income. On account of the defeasance provision, the so-called special option did not qualify for deferral or treatment as capital gain under section 1234.19 The Ninth Circuit commented:
As a consequence Owners were not bound to sell and convey; they were afforded an alternative. And for that reason the "Special Option” did not create a "privilege or option” entitled to be accorded capital gains treatment by 26 U.S.C. §1234. That section is limited in application to unilateral agreements which are inflexibly binding upon the purported vendor. * * * [450 F.2d at 1049.]
The common law principles applicable to option contracts are well settled. An option contract has two elements: (1) A continuing offer to do something, or to forbear, which does not become a contract until accepted; and (2) an agreement to leave an offer open for a specified or reasonable period of time.20 Koch v. Commissioner, 67 T.C. 71, 82 (1976); Carter v. Commissioner, 36 T.C. 128, 130 (1961); Drake v. Commissioner, 3 T.C. 33, 37 (1944).
If the optionee’s power to accept is dependent upon some further act of the offeror, then there is no unconditional option contract, rather the offeree has nothing more than a conditional preferential right of first refusal.21 An offer that does not create an unconditional power of acceptance in the offeree has been called an illusory promise. See 1 A. Corbin, Contracts, sec. 145, and vol. 1A, sec. 261 (1963 ed. & Supp. 1982).
Applying the foregoing law to the agreement herein, we think it clear that petitioner’s offer to sell extracted gold at a fixed unit price was illusory. This is so because the offer did not create in the optionholder an unconditional power of acceptance. The so-called gold option, when construed from its four corners, appears to be nothing more than a preferential right of first refusal. As we view the agreement, the offeree’s power of acceptance is severely limited by the condition that it is subject to the petitioner’s decision to mine gold. The optionee has no power to compel him to produce. He has, at most, a mere expectancy of purchasing gold. Booker v. Commissioner, 27 T.C. 932 (1957).
Petitioner describes his financing vehicle as a "conditional option” and refers to the "conditional nature of the option.” We have found no case law, nor has he cited us to any, in support of his hypothesis that such an option qualifies for tax deferral. To the contrary, the courts have treated such an "option” as vague and unenforceable. See Saunders v. United States, supra; Booker v. Commissioner, supra. We conclude that the right to purchase extracted gold was not a binding, legal option.
In summation, we conclude that there is no dispute as to any fact material to the motions for partial summary judgment and that a decision on the issues presented by such motions may be rendered as a matter of law. Accordingly, we hereby:
(a) Grant the respondent’s motion for partial summary judgment to the effect that the nonrecourse obligation which the petitioner incurred in 1978 upon the execution of the mineral loan agreement is too contingent and uncertain to be considered a valid indebtedness for tax purposes, and deny the petitioner’s motion to the contrary; and
(b) Grant respondent’s motion for partial summary judgment to the effect that the purported option granted by the petitioner in 1979 is not a true option for tax purposes and the amount received in consideration therefore does not qualify for tax deferral; and deny the petitioner’s motion to the contrary.
An appropriate order will be entered.
