The Social Security Administration appeals the amount of back pay the district court awarded Stephen A. Arneson. We affirm in part and reverse in part.
I. BACKGROUND
This dispute is before us for the third time. We will discuss only those facts relevant to this appeal. Stephen A. Arneson sued the Social Security Administration (SSA), claim
The district court dismissed the suit and Arneson appealed. This court remanded to determine whether the SSA failed to make reasonable accommodations for Arneson’s disability.
Arneson v. Heckler,
First, the SSA contends that the district court erroneously awarded Arneson prejudgment interest accruing from his unlawful discharge. Second, the SSA contends that the district court erred in awarding Arneson additional monies to compensate him for the adverse tax consequences associated with receiving twelve years of back pay in two payments. Finally, the SSA contends that the district court erred in declining to reduce Arneson’s back pay award by the amount of disability retirement benefits that Arneson received.
II. DISCUSSION
A. Prejudgment Interest
The no-interest rule provides that sovereign immunity generally precludes a party from recovering interest in a suit against the United States.
See Library of Congress v. Shaw,
The Rehabilitation Act does not provide for prejudgment interest; however, it expressly incorporates the “remedies, procedures and rights” of Title VII. 29 U.S.C. § 794(a)(1). Title VII of the Civil Rights Act of 1964, provides that a court may order an employer to reinstate employees “with or without back pay” or order “any other equitable relief as the court deems appropriate.” 42 U.S.C. § 2000e-5(g)(l). Arneson argues that Congress waived sovereign immunity from interest under Title VII or, alternatively, that the Back Pay Act, 5 U.S.C. § 5596, provides the necessary waiver. 3
The Supreme -Court has previously held that Title VII does not waive the federal government’s sovereign immunity from interest.

Shaw,
[T]here can be no consent by implication or by use of ambiguous language. Nor can an intent on the part of the framers of a statute or contract to permit the recovery of interest suffice where the intent is not translated into affirmative statutory or contractual terms. The.consent necessary to waive the traditional immunity must be express, and it must be strictly construed.

(alternation in original) (quoting
United States v. N. Y. Rayon Importing Co.,
After
Shaw,
Congress amended Title VII, expressly waiving sovereign immunity from interest. 42 U.S.C. § 2000e-16(d). Neither party disputes that the district court properly awarded Arneson interest beginning on November 21,1991, the amendment’s effective date. However, the 1991 amendment does not apply retroactively.
See Huey v. Sullivan,
The Back Pay Act generally provides certain federal agency employees with a monetary remedy for “unjustified or unwarranted personnel action which has resulted in the withdrawal or reduction” of the employees’ pay. 5 U.S.C. § 5596(b)(1)'. The Back Pay Act did not provide for interest against the United States until Congress amended it in 1987. 5 U.S.C. § 5596(b)(2)(A).
Arneson cites three circuit decisions for the proposition that the amended Back Pay Act waives the government’s sоvereign immunity from interest awards in Rehabilitation Act and Title VII cases.
See Brown v. Secretary of the Army,
In
Brown,
the court held that the Back' Pay Act waives the federal government’s sovereign immunity from interest in Title VII cases.
Brown,
We find this reasoning unpersuasive. In
Loeffler,
We hold that to provide the sovereign immunity waiver absent in Title VII, the separate statute must, at a minimum, unequivocally express Congress’s intent to waive sovereign immunity under Title VII.
Cf. McGehee v. Panama Canal Comm’n,
In this Rehabilitation Act ease, Arneson recovered back pay under Title VII’s remedial provisions. He did not rely upon the Back Pay Act to recover back pay, but now asserts that the Back Pay Act provides the necessary waiver of sovereign immunity. The Back Pay Act language relied upon by Arneson states that “[a]n amount payable under paragraph (1)(A)(I) of this subsection shall bе payable with interest.” 5 U.S.C.
The Supreme Court’s decisions addressing sovereign immunity and the no-intеrest rule buttress our holding. The Court has instructed us to construe the scope of such waivers in the sovereign’s favor,
see Shaw,
B. Tax Enhancement Damages
The district court awarded Arneson additional monies to compensate Arneson for the adverse tax consequences from receiving back pay in two payments (tax enhancement award). The SSA argues that tax enhancement awards are not. available under Title VII and that, if available, Congress has .not waived sovereign immunity from these awards.
If the tax enhancement remedy is available under Title VII, we find it analogous to the prejudgment interest remedy,
see Manko v. United States,
We dо not believe that Congress has authorized the tax. enhancement ■ remedy against the federal government. Nowhere within the statutory framework of the Rehabilitation Act or Title VII, has Congress expressly waived sovereign immunity from tax enhancement damages. The mere fact that Congress intended that discrimination victims receive a full measure of back pay does not amount to an unequivocal and express waiver of sovereign immunity. We therefore reverse the district court’s award of tax enhancement damages. 7
C. Disability Retirement Annuity
After his unlawful discharge, Arneson received Civil Service Retirement System (CSRS) disability retirement benefits (disability benefits) in the amount of $72,241.87. The SSA argues that we should deduct the amount of these benefits from Arneson’s back pay award because Arneson would otherwise receive a double recovery. We disagree.
The Title VII back pay remedy is limited by 42 U.S.C. § 2000e-5(g), which provides in part, “[i]nterim. еarnings ... by the person or persons discriminated against shall operate to reduce the back pay otherwise allowable.” This provision prevents employment discrimination victims from recovering twice for the same injury. The SSA argues that Arneson’s disability benefits constitute interim earnings.
Because the National Labor Relations Act provides the model for the Title VII back pay
The common law collateral source rule holds that the defendant’s liability shall not be reduced merely because the plaintiffs net damages are reduced by payments received from others.
See Gullett Gin,
We have previously' áddressed this issue under the Age' Discrimination in Employment Act of 1967, 29 U.S.C. § 621.
See, e.g., Smith v. World Ins. Co.,
We affirm the district court’s refusal to deduct Arneson’s disability benefits from his back pay award becaúse these benefits were from a collateral source and should not be considered interim earnings.
8
Cf. Eichel v. New York Central R.R. Co.,
D. Attorney’s Fees and Costs
The district court awarded Arneson attorney’s fees totaling $178,610 and other costs totaling $9,381.13. The SSA argues that Arneson should not recover the fees and costs related to any issues that Arneson loses on appeal because Arneson would no longer be the prevailing party with respect to those issues. We agree.
Under Title VII, the district court may, in its discretion, award “the prevailing party” a treasonable attorney’s fee (including expert fees) as part of the costs.” 42 U.S.C. § 2000e-5(k).
9
In awarding attorney’s fees and costs when the plaintiff has only achieved limited or partial success, the court must consider “whether the expenditure of counsel’s time was reasonable in relation to the success achieved.”
Hensley v. Eckerhart,
We 'find Arneson’s post-trial claims for prejudgment interest and a tax enhancement award distinct and unrelated to those that he' has prevailed on,
see id.
at 437 n. 12,
III. CONCLUSION
For the foregoing reasons, we affirm the district court decision in part and reverse in part. We remand the case for á redetermination оf interest and costs, including attorney’s fees.
Notes
. The Supreme Court has also held that just compensation under the Fifth Amendment takings clause waives sovereign immunity from interest.
Smyth v. United States,
. Sovereign immunity is a jurisdictional question which the government can raise at any time.
See, e.g., Preferred Risk Mnt. Ins. Co. v. United States,
. In
Shaw,
the plaintiff argued that Congress waived sovereign immunity from interest under Title VII because Title VII holds the United States "liable 'the same as a private person’ for 'costs,' including ‘a reasonable attorney's fee.' ”
Shaw,
. In
Brown,
the plaintiffs brought an unlawful failure to promote claim under Title VII and not the Back Pay Act.
Brown,
. In light of this finding, we need not address Arneson’s argument that the 1987 Back Pay Act amendment applies retroactively.
. Because we believe Congress has not unequivocally expressed its intention to waive the federal government’s sovereign immunity from this tаx enhancement award, we need not decide whether plaintiffs may recover this type of award against private parties.
. This case is distinguishable from
Beshears v. Asbill,
. Congress expressly waived the government's sovereign immunity from costs and attorney’s fees. 42 U.S.C. § 2000e-5(k) ("mhe United States shall be liable for costs the same as a ' private person.”).
