We consider two principal issues in this appeal: first, the extent to which, in matters submitted to a magistrate, a litigant’s failure to present his contentions either to the magistrate or the district court will bar him from raising those contentions on appeal; and second, whether the conclusion of the Secretary of Health and Human Services that appellant was an employee within the meaning of Title II of the Social Security Act, 42 U.S.C. §§ 401-433, is supported by substantial evidence.
Facts
Appellant Tommy V. Greenhow received retirement insurance benefits under section 202(a) of the Social Security Act, 42 U.S.C. § 402(a) (1976), for the calendar years 1979, 1980 and 1981. Greenhow was later notified that his benefits were subject to retro *635 active work deductions because he had earned $12,000 in each of those years. He requested a hearing before an administrative law judge, claiming that the $12,000 figure did not reflect business expenses that he was entitled to deduct as a “commissioned employee” respоnsible for paying his own expenses.
The AU ruled against Greenhow, and the appeals council denied review. Green-how then sought judicial review under section 205(g) of the Act, 42 U.S.C. § 405(g) (1982). The district court remanded to the Secretary for an evidentiary hearing on the question whether Greenhow was an employee or an independеnt contractor. After a supplemental hearing was held, the AU found that Greenhow was indeed an employee, and the appeals council affirmed. Greenhow again sought judicial review.
Pursuant to local rule, Greenhow’s case was automatically referred to a magistrate for initial consideration of thе cross-motions for summary judgment. E.D.Cal.R. 302(b)(13). The magistrate concluded that the Secretary’s finding was supported by substantial evidence and, accordingly, recommended that summary judgment be granted. Greenhow timely filed an objection to the magistrate’s proposed findings and recommendation; the sole basis for the objection was that the regulation that prevents employees from deducting business expenses was “unreasonable.” The district court, without addressing Greenhow’s objection, adopted the magistrate’s recommendation and granted summary judgment for the Secretary. Greenhow appeals.
Discussion
I
A. Greenhow first claims that the Secretary’s finding that he wаs an employee rather than an independent contractor is not supported by substantial evidence. This contention was presented to the magistrate, who recommended that it be rejected. Greenhow did not object to this recommendation in the district court. The Secretary therefore contends that Grеenhow has waived his right to raise this issue on appeal.
It is clear that failure to object to proposed findings of fact entered by magistrates in matters referred to them under 28 U.S.C. § 636(b)(1) (1982) waives the opportunity to contest those findings on appeal.
See Britt v. Simi Valley Unified School Dist.,
In
McCall,
the magistrate found that an administrative agency’s decision adverse to plaintiff was supported by substantial evidence, and recommended that the plaintiff’s challenge to a rule applied by the agency be rejected. The district court adopted these recommendations. On appeal, we held that plaintiff’s failure to object to either of these conclusions of law prevented him from challenging them.
Three years after
McCall,
however, another panel of this court reached a directly contrary conclusion, holding that “failure to file objections does not waive the right to appeal the district court’s conclusions of law.”

Brawner v. Secretary of Health & Human Servs.,
Pursuant to section 210(j)(2) of the Social Security Act, the existence of an emplоyer-employee relationship is to be determined “under the usual common law rules.” 42 U.S.C. § 410(j)(2) (1982). The Secretary has promulgated a nonexclusive list of factors to be considered in determining whether an individual is an employee. 20 C.F.R. § 404.1007(b) (1987). Among the factors that may indicate employee status are the following:
(1) The person you work for may fire you.
(2) The person you work fоr furnishes you with tools or equipment and a place to work.
(3) You receive training from the person you work for or are required to follow that person’s instructions.
(4) You must do the work yourself.
(5) You do not hire, supervise, or pay assistants (unless you are employed as a foreman, manager, or supervisor).
(6) The person you work for sets your hours of wоrk, requires you to work full-time, or restricts you from doing work for others.
(7) The person you work for pays your business or traveling expenses.
(8) You are paid by the hour, week or month.
Id.
Greenhow worked for a radio station as a sales representative for advertising time and as a talk-show host. The evidence revealed that: (1) Greenhow could be terminated at any time by Knox LaRue, the owner of the station; (2) the station provided him with a desk, office space and some broadcasting equipment, but he furnished some of his broadcasting equipment as well as an automobile for his calls on prospective purchasers of advertising time; (3) he was subject to supervision by LaRue, and if he was unable tо call on a client someone else could be assigned to the call; (4) Greenhow did his work himself, although there is no evidence of any express requirement that he do so; (5) he did not have any assistants, and the station provided him with clerical support (although Greenhow preferred to rely on his wife to assist him instead); (6) while he did nоt have fixed hours of work, he felt obligated to put in a fairly uniform number of hours over a given period of time, although he was apparently permitted to do some free-lance work in his spare time; (7) the station advanced him $150 per month for expenses, and he also was reimbursed for some, but not all, additional expenses for which he submitted statements; and (8) he was paid a monthly salary that was recorded as wages on his W-2 forms.
Greenhow’s relationship with the station thus exhibits nearly all of the characteristics of an employer-employee relationship. Moreover, Greenhow received the employee benefits provided by the station, and LaRue characterized him as an “employee.” Considering the record as a whole, we conclude that the Secretary’s determination that Greenhow was an employee rather than an independent contractor is supported by substantial evidence.
II
A. Greenhow also contends that even if hе is an employee he should be entitled to deduct his business expenses notwithstanding 20 C.F.R. § 404.1045 (1987), which provides:
Amounts that your employer pays you specifically — either as advances or reimbursements — for traveling or for other ordinary and necessary expenses incurred, or reasonably expected to be incurred, in your emрloyer’s business are not wages. The employer must identify these travel and other expenses either by making a separate payment or by specifically stating the separate amounts if both wages and expense allowances are combined in a single payment.
Greenhow argues that it is “unreasonable” for the regulations to prevent him from deducting his expenses merely because his employer pays him a lump sum each month rather than separately reimbursing his expenses.
*638
Section 404.1045 was promulgated pursuant to the Secretary’s statutory authority “to make rules and regulations ... not inconsistent with the provisions of this sub-chapter, which аre necessary or appropriate to carry out such provisions_” Social Security Act § 205(a), 42 U.S.C. § 405(a) (1982). “Where, as here, the statute expressly entrusts the Secretary with the responsibility for implementing a provision by regulation, our review is limited to determining whether the regulations promulgated exceeded the Secretаry’s statutory authority and whether they are arbitrary and capricious.”
Heckler v. Campbell,
Nothing in the statute conflicts with section 404.1045. Indeed, Congress explicitly provided for differential treatment of business expenses incurred by wage-earners and self-employed persons by defining an individual’s “earnings for a taxable year” as “(i) the sum of his wages for servicеs rendered in such year and his net earnings from self-employment for such year, minus (ii) any net loss from self-employment for such year.” Social Security Act § 203(f)(5)(A), 42 U.S.C. § 403(f)(5)(A) (1982) (emphasis added); see also id. §§ 211(a), (b), 42 U.S.C. § 411(a), (b) (1982 & Supp. Ill 1985) (defining “net earnings from self-employment” and “self-employment income”).
Moreover, as the Second Circuit noted in
Colby v. Harris,
B. Finally, even if the regulation is valid, Greenhow contends he is not subject to its literal language because he should be treated as a “traveling salesman” rather than a mere employee. He relies on a line of eases that permit traveling salesmen to deduct business expenses from their gross income for purposes of computing retiremеnt benefit overpayments, even though their employers do not specifically designate portions of their remuneration as expense reimbursements.
See, e.g., Angell v. Flemming,
The Secretary again responds that Greenhow has waived his right to make this argument, this time by failing to present it to the magistrate in the first instance. Instead, Greenhow first raised this, issue in his objection to the magistrate’s report. The district court apparently concluded that this issue was not properly before it; its order granting summary judgment adopted the magistrate’s conclusion that “the sole issue before the court is whether there is substantial evidence to support the Secretary’s finding that plaintiff was an employee,” CR 22, at 2, and did not even discuss Greenhow’s new contention that he was entitled to deduct his expenses as a traveling salesman.
The district court’s refusal to consider Greenhow’s belated claim was entirely appropriate. Under the district court’s local rules, Greenhow was required to present his motion for summary judgment to the magistrate. E.D.Cal.R. 302(b)(13), 305(a). The district court’s order of submission required Greenhow’s motion to “contain appropriate points and authorities dealing with the specific legal issues involved in this case.” CR 2, at 3 115. Permitting Greenhow to offer new contentions to the district court would circumvent these rules and the district court’s order. Moreover, allowing parties to litigate fully their case before the magistrate and, if unsuccessful, to change their strategy and present a different theory to the district court would frustrate the purpose of the Magistrates Act. We do not believe that the Magistrates Act was intended to give litigants an opportunity to run one version of their case past the magistrate, then another past the district court.
Arguments raised for the first time on appeal have traditionally been held
*639
to be barred, absent exceptional circumstances or a convincing explanation for the failure to present them to the court below.
See, e.g., McCall,
Greenhow raises no claim of exceptional circumstances to justify or excuse his failure to make the argument before the magistrate. His only explanation for the default is that he “did not find the four ‘traveling salesman’ cases until the prеparation of his Objections to Magistrate’s Proposed Findings and Recommendation.” Petition for Rehearing at 3. Mere failure to discover a new .legal theory until after the magistrate has ruled falls far short of the type of compelling circumstance that will permit a party to escape the waiver rule. The district court properly refused to consider this issue, and we are therefore barred from reviewing it on appeal.
AFFIRMED.
