delivered the opinion of the Court.
Petitioner, the taxpayer, with extensive investments in real estate, bonds and stocks, devoted a considerable portion of his time to the oversight of his interests and hired others to assist him in offices rented for that purpose. For the tax years in question, 1932 and 1933, he claimed the salaries and expenses incident to looking after his properties were deductible under § 23 (a) of
Petitioner’s financial affairs were conducted through his New York office pursuant to his personal detailed instructions. His residence was in Paris, France, where he had a second office. By cable, telephone and mail, petitioner kept a watchful eye over his securities. While he sought permanent investments, changes, redemptions, maturities and accumulations caused limited shif-tings in his portfolio. These were made under his own orders. The offices kept records, received securities, interest and dividend checks, made deposits, forwarded weekly and annual reports and undertook generally the care of the investments as instructed by the owner. Purchases were made by a financial institution. Petitioner did not participate directly or indirectly in the management of the corporations in which he held stock or bonds. The method of handling his affairs under examination had been employed by petitioner for more than thirty years.
The Board of Tax Appeals* 3 held that these activities did not constitute carrying on a business and that the expenses were capable of apportionment between the real estate and the investments. The Circuit Court of Appeals affirmed, 4 and we granted certiorari because of conflict. 5
Petitioner urges that the “elements of continuity, constant repetition, regularity and extent” differentiate his activities from the occasional like actions of the small investor. His activity is and the occasional action is not “carrying on business.” On the other hand, the respondent urges that “mere personal investment activities never constitute carrying on a trade or business, no matter how much of one’s time or of one’s employees’ time they may occupy.”
Since the first income tax act, the provisions authorizing business deductions have varied only slightly. The Revenue Act of 1913
6
allowed as a deduction “the necessary expenses actually paid in carrying on any business.” By 1918 the present form was fixed and has so continued.
7
No regulation has ever been promulgated which interprets the meaning of “carrying on a business,” nor any rulings approved by the Secretary of the Treasury, i. e., Treasury Decisions.

While the Commissioner has combated views similar to petitioner’s in the courts, sometimes successfully

the petitioner urges that the Bureau accepted for years the doctrine that the management of one’s own securities might be a business where there was sufficient extent, continuity, variety and regularity. We fail to find, such a fixed administrative construction in the examples cited. It is true that the decisions are frequently put on the ground that the taxpayer’s activities were sporadic but it does not follow that had those activities been continuous the Commissioner would not have used the argument advanced here, i. e., that no amount of personal investment management would turn those activities into a business. Evidently such was the Government’s contention in the
Kales
Petitioner relies strongly on the definition of business in Flint v. Stone Tracy Company: 19 “ ‘Business’ is a very comprehensive term and embraces everything about which a person can be employed.” This definition was given in considering whether certain corporations came under the Corporation Tax law which levies a tax on corporations engaged in business. The immediate issue was whether corporations engaged principally in the “holding and management of real estate” 20 were subject to the act. A definition given for such an issue is not controlling in this dissimilar inquiry. 21
To determine whether the activities of a taxpayer are “carrying on a business” requires an examination of the facts in each case. As the Circuit Court of Appeals observed, all expenses of every business transaction are not deductible. Only those are deductible which relate to carrying on a business. The Bureau of Internal Revenue has this duty of determining what is carrying on a business, subject to reexamination of the facts by the Board of Tax Appeals
22
and ultimately to review on the law by the
The petitioner makes the point that his activities in managing his estate, both realty and personalty, were a unified business. Since it was admittedly a business in so far as the realty is concerned, he urges, there is no statutory authority to sever expenses allocable to the securities. But we see no reason why expenses not attributable, as we have just held these are not, to carrying on business cannot be apportioned. It is not unusual to allocate expenses paid for services partly personal and partly business. 25
