Plaintiff-Appellant Merrill Lynch Financial Business Services, Inc. (“Merrill Lynch”) brought a diversity action to collect on a debt that DefendanL-Appellee Arnold Nudell guaranteed. Mr. Nudell, in response, filed a motion to dismiss based upon the Rooker-Feldman doctrine, which the district court granted. We take jurisdiction pursuant to 28 U.S.C. § 1291, REVERSE, and REMAND.
I. BACKGROUND
This case comes to us from a motion to dismiss. We present the facts, therefore, as stated in the Complaint. On August 15, 1995, Genesis Technologies, Inc. (“GTI”) executed two Notes, Loans, and Security Agreements in favor of Merrill Lynch in the amount of $300,000.00. On this same day, Mr. Nudell, President of GTI, executed an unconditional guaranty of each note in which he agreed, among other things, that Merrill Lynch “shall not be required at any time, as a condition of the undersigned’s obligation hereunder, to resort to payment from [GTI.]”
GTI failed to repay the loans to Merrill Lynch, and, in May 2001, Mr. Nudell and Merrill Lynch entered into a forbearance agreement delaying repayment of the loans until July 31, 2001. Mr. Nudell failed to repay the loans by that date, which, given the accumulation of interest and a line-of credit increase, amounted to $591,185.15 plus late fees.
*1074Merrill Lynch then launched a collection action in Colorado state court against both GTI and Mr. Nudell. Unbeknownst to Merrill Lynch, GTI had filed for bankruptcy on the previous day in the Bankruptcy Court for the District of Colorado. In December 2001, Mr. Nudell filed in Colorado state court a motion to dismiss or, in the alternative, to stay pending the bankruptcy proceeding.
The state court granted the motion to dismiss on May 1, 2002, stating in full:
THE COURT, having considered Defendant Nudell’s Motion to Dismiss and otherwise being fully advised in the premises, GRANTS the Motion. Now, therefore, IT IS ORDERED that the action is dismissed without prejudice.
GTI’s bankruptcy case was closed on May 6, 2002. One week later, Merrill Lynch commenced the present diversity action in the United States District Court for the District of Colorado only against Mr. Nudell, seeking to enforce his guaranty of the GTI loans.
Mr. Nudell then moved to dismiss for, inter alia, lack of subject matter jurisdiction. He argued that, because the state court dismissed Merrill Lynch’s collection action without prejudice, the Rooker-Feldman doctrine barred a federal court from taking subject matter jurisdiction over Merrill Lynch’s claim. The district court granted Mr. Nudell’s motion and dismissed the complaint. Merrill Lynch filed a timely notice of appeal.
II. STANDARD OF REVIEW
Mr. Nudell raised this issue in a motion to dismiss for lack of jurisdiction pursuant to Federal Rule of Civil Procedure 12(b)(1). “Rule 12(b)(1) motions generally take one of two forms. The moving party may (1) facially attack the complaint’s allegations as to the existence of subject matter jurisdiction, or (2) go beyond allegations contained in the complaint by presenting evidence to challenge the factual basis upon which subject matter jurisdiction rests.” Maestas v. Lujan, 351 F.3d 1001, 1013 (10th Cir.2003) (internal citation and quotations omitted). We review de novo the district court’s dismissal for lack of subject matter jurisdiction and review for clear error any jurisdictional findings of fact. Id.
III. DISCUSSION
On appeal, Mr. Nudell urges that the state court’s dismissal without prejudice triggers application of the Rooker-Feldman doctrine. Mr. Nudell concedes, as he must, that “[t]he state court’s order did not have preclusive effect” because, under Colorado law, a dismissal without prejudice means a dismissal not on the merits of the case. See, e.g., Wistrand v. Leach Realty Co., 147 Colo. 573, 364 P.2d 396, 397 (1961). Nevertheless, Mr. Nudell contends that the Rooker-Feldman doctrine applies because it “is not limited to situations in which the state court’s decision would be entitled to res judicata effect, for if so there would be no need for the doctrine.” Although we agree with Mr. Nudell that the Rooker-Feldman doctrine has a broader scope than res judicata, we find the doctrine inapplicable in this instance.
The Rooker-Feldman doctrine1 establishes, as a matter of subject-matter *1075jurisdiction, that only the United States Supreme Court has appellate authority to review a state-court decision. See 28 U.S.C. § 1257(a) (establishing Supreme Court jurisdiction to review certain “[f]inal judgments or decrees rendered by the highest court of a State in which a decision could be had”). Thus, in applying the Rooker-Feldman doctrine, we focus on whether the lower federal court, if it adjudicated plaintiffs claims, would effectively act as an appellate court reviewing the state court disposition. See Dist. of Columbia Court of Appeals v. Feldman, 460 U.S. 462, 483 n. 16, 103 S.Ct. 1303, 75 L.Ed.2d 206 (1983) (Under the Rooker-Feldman doctrine, “lower federal courts possess no power whatever to sit in direct review of state court decisions.”); Kenmen Eng. v. City of Union, 314 F.3d 468, 476 (10th Cir.2002) (“Rooker-Feldman protects state-court judgments from impermissible appellate review by lower federal courts.”).
Given this focus, it is not surprising that the Rooker-Feldman doctrine shares a close affinity to claim and issue preclusion. Indeed, in many circuits, the Rooker-Feldman doctrine is coextensive with preclusion doctrine. See, e.g., In re Lease Oil Antitrust Litig. (No. II), 200 F.3d 317, 319 n. 1 (5th Cir.2000); Moccio v. New York State Office of Court Admin., 95 F.3d 195, 199-200 (2nd Cir.1996); Robinson v. Ari-yoshi, 753 F.2d 1468, 1472 (9th Cir.1985), vacated on other grounds, 477 U.S. 902, 106 S.Ct. 3269, 91 L.Ed.2d 560 (1986).
In the Tenth Circuit, however, we apply the Rooker-Feldman doctrine in a slightly broader fashion. “[T]he Rooker-Feldman doctrine — unlike res judicata— does not distinguish between ‘temporary’ and ‘final’ orders.” Kenmen Eng., 314 F.3d at 474; accord Charchenko v. City of Stillwater, 47 F.3d 981, 983 n. 1 (8th Cir.1995) (“We note that Rooker-Feldman is broader than claim' and issue preclusion because it does not depend on a final judgment' on the merits. Aside from this distinction the doctrines are extremely similar.”). Thus, under our law, the Rooker-Feldman doctrine mirrors claim- and issue preclusion, except that' Rooker-Feldman applies to temporary and non-final orders. See Kenmen Eng., 314 F.3d at 474.
Pursuant to Supreme Court precedent, we apply the Rooker-Feldman doctrine: (1) to those federal claims actually decided by a state court, and (2) to those federal claims inextricably intertwined with a state court judgment. Id. at 475. When a state court does not pass on the merits of the claim the “actually decided” test is not satisfied. Pittsburg County Rural Water Dist. No. 7 v. City of McAlester, 358 F.3d 694, 707 (10th Cir.2004) (“Plainly, the merits of [plaintiffs] claims *1076for relief ... were not actually decided by the Oklahoma district court, which performed no merits analysis and dismissed [plaintiffs] appeal due to defective service of process.”).
To discern whether the “inextricably intertwined” standard applies, we ask
whether the injury alleged by the federal plaintiff resulted from the state court judgment itself or is distinct from that judgment. Three related concepts — injury, causation, and redressability — inform this analysis. In other words, we approach the question by asking whether the state-court judgment caused, actually and proximately, the injury for which the federal-court plaintiff seeks redress. Kenmen Eng., 314 F.3d at 476 (internal citations and quotations omitted).
In applying these principles, our recent Pittsburg County opinion held that a dismissal not on the merits does not trigger application of the inextricably intertwined test. Pittsburg County, 358 F.3d at 707 (holding that because the state court did not reach the plaintiffs federal claims on the merits, the federal “claims do not result from the state court judgments dismissing [them]”). Thus, the “inextricably intertwined” test is not satisfied when a federal plaintiff brings claims that the state court did not review on the merits. See id. at 708 n. 3.
Here, the state court, by dismissing without prejudice, did not pass on the merits of the case. Although Mr. Nudell suggests numerous on-the-merits grounds that he presented in his state court motion on which the state court could have relied, given the dignity and respect due a state court decision, we take the court at its word that it “dismissed without prejudice.” As the Colorado Supreme Court held in Wistrand, dismissal without prejudice means not on the merits:
Here the order of dismissal expressly specifies that it is without prejudice. To now urge that the dismissal prejudiced [plaintiffs] right to have his claim adjudicated does violence to the rule and the court’s order. It is difficult to see how the court could have better assured [plaintiff] that he could again go to court and have his claim adjudicated on the merits. Wistrand, 364 P.2d at 397.
Because the state court, by dismissing without prejudice, did not reach the merits of Merrill Lynch’s claim, neither the actually decided nor the inextricably intertwined tests are satisfied. Hence, the Rooker-Feldman doctrine does not apply. See Pittsburg County, 358 F.3d at 708 n. 3 (citing Whiteford v. Reed, 155 F.3d 671, 674 (3d. Cir.1998) (“This court has consistently held that where a state action does not reach the merits of a plaintiffs claims, then Rooker-Feldman does not deprive the federal court of jurisdiction.”) & Charles Alan Wright & Arthur R. Miller, Federal Practice and Procedure § 4469.1, at 130-31 (2d ed. 2002) (“A decision not on the merits also does not oust federal jurisdiction to decide on the merits.”)).
IV. CONCLUSION
As the Rooker-Feldman doctrine is inapplicable here, we REVERSE the district court’s dismissal and REMAND for further proceedings consistent with this opinion.
