The chronology of events affecting the rights of the claimants was as follows: April 1, 1947, town property tax, $612.95; April 1, 1948, town property tax, $690.85; August 6, 1948, notice of tax lien filed by United States of America; August 24, 1948, defendant’s property advertised for 1947 property taxes; September 25, 1948, defendant’s property sold for 1947 tax; April 1, 1949, town property tax, $383; August 12, 1949, temporary receivers appointed; August 23, 1949, defendant’s property advertised for 1948 property tax; September 24, 1949, defendant’s property sold for *414 1948 tax; January 30, 1950, permanent receiver appointed; April 1, 1950, town property tax, $421. The dates of assessment of the annual property taxes do not appear. •
The town’s exception to the decree that the claim of the United States has priority over the claim of the town for the 1949 tax has been expressly waived.
The United States takes the position that the defendant’s machinery was personal property, and relies upon the decision in Flack v. Byse Agency, Inc., 96 N. H. 335, for the proposition that no lien for taxes attaches to personalty. This argument is sufficiently answered by statute. Machinery is taxable as real estate (R. L., c. 73, s. 8; Kolodny v. Laconia, 96 N. H. 337) and as such is made subject to a lien “for all taxes thereon.” R. L., c. 80, s. 17. If it may be personal property for purposes other than taxation the force of the tax statute is not affected. Kolodny v. Laconia, supra; O’Donnell v. Meredith, 75 N. H. 272; Redding &c. Ass’n v. Epping, 88 N. H. 321, 322, 323. The tax becomes due on April 1 (R. L., c. 74, s. 1; c. 75, s. 1; Saidel v. Felsher, 83 N. H. 582), is required to be assessed before July 1 (R. L., c. 77, s. 9, amended by Laws 1947, c. 221) and is secured by a lien upon the real estate upon which it is assessed continuing “until one year from October first following the assessment.” R. L., c. 80, s. 17. It is settled by our decisions that the assessment of a tax is in the nature of a judgment, enforced by a warrant instead of an execution. Boody v. Watson, 64 N. H. 162, 167; Jaffrey v. Smith, 76 N. H. 168, 171; Nottingham v. Company, 84 N. H. 419. See also, Automatic Sprinkler Corp. v. Marston, 94 N. H. 375. In execution of the warrant real estate and property taxable as such may be sold in foreclosure of the statutory lien. R. L., c. 80, s. 18. The defendant’s machinery was properly taxed as real estate, and was subject to the lien in such case provided.
The liens which the United States seeks to enforce arise under the provisions of 26 U. S. C. s. 3670, providing that a tax which the taxpayer neglects or refuses to pay shall be a lien in favor of the United States “upon all property and rights to property . . . belonging to such person.” Such lien arises when the assessment list is received by the collector (s. 3671), subject to the qualification that it “shall not be valid as against any mortgagee, pledgee, purchaser, or judgment creditor until notice thereof has been filed” in the office of the Clerk of the United States District Court (s. 3672). It is argued that the town does not come within the class of per *415 sons entitled to the benefit of the latter section, while the town asserts that it is protected as a “judgment creditor.”
It cannot be doubted that the interpretation of the statute is a question of federal law.
United States
v.
Security Tr. & Sav. Bk.,
The United States further relies upon 31 U. S. C. s. 191, which provides in part: “Whenever any person indebted to the United States is insolvent . . . the debts due to the United States shall be first satisfied; . . .” This section creates no lien in favor of the United States but affects priority only.
United States
v.
O’Dell,
160 F. (2d) 304. Although the question has never been determined by the United States Supreme Court, the decisions of that court strongly indicate that the priority established by this section may be overcome by a “fully perfected and specific lien.”
Illinois
v.
Campbell,
The effect of the federal statute depends upon the status of the lien at the time when insolvency occurs.
Massachusetts
v.
United States,
There can be no question but that the town’s lien for the 1947 taxes complied with these requirements. The machinery had been both advertised and sold to the town before insolvency arose. Thus the lien had not only been perfected but foreclosure had been instituted. While advertisement and sale for the 1948 tax did not occur until after August 12, 1949, we are not satisfied that the Trial Court erred in ruling that the lien for that year’s taxes was likewise “specific and effective.” The amount was no longer subject to change upon abatement or appeal, the time for such action having long previously expired. R. L., c. 77, s. 14. The fact that advertisement and sale had not then taken place, does not establish that the lien was not perfected. Like the foreclosure of a mortgage, the sale for taxes was a method of enforcement rather than perfection of the lien. On August 12, 1949, all that was required to fully perfect the lien had been accomplished and what was thereafter done was in collection of the tax. The amount of the lien and the property to which it attached were then definitely
*417
established.

There remains for consideration the exception of the town to the ruling that expenses of the receivership did not include the 1950 tax, and that' the claims of the United States are superior to the claim of the town for the tax for that year. No claim is made by the United States to preference over the expenses of receivership, which are commonly considered to come ahead of taxes.
