How did California treat materials used by dental laboratories to repair or reline dentures when the laboratory made one lump-sum charge?

Plain-English summary

A requester asked in an October 31 letter how sales tax applied when dental laboratories repaired or relined dentures and said the opinion might be published in the California Dental Laboratory Society bulletin. Counsel applied the second paragraph of former Ruling 26 to situations in which material value was insignificant relative to labor and no separate material charge was made.

Counsel said that rule appeared applicable to denture repairers and treated the laboratory as consumer of the materials. When the laboratory billed one lump sum, tax applied to its cost price for the repair materials rather than treating them as separately sold items.

Source and live-annotation limits

The PDF does not reproduce the October 31 request, dentures, repair or relining work, material descriptions and values, labor charge, billing, purchases, customer, completed transaction, return, tax payment, audit, assessment, or later outcome. It says Ruling 26 was enclosed, but the PDF contains no enclosure. It gives no numerical threshold or other definition of “insignificant.”

The live annotation preserves only that a dental laboratory repairing or relining dentures consumed materials when no separate material charge was made. It omits the October 31 publication request, Ruling 26 and missing enclosure, insignificant-value comparison to labor, tentative “appears applicable” wording, lump-sum charge, cost-price tax measure, undefined threshold, absent records, and later-outcome gap.

What this means for you

Dental laboratories and tax professionals

Document that the work repairs or relines an existing denture, the materials and their value relative to labor, whether charges are separate or lump sum, material purchase tax, customer bills, and returns. The source supplies no numeric insignificance threshold.

Common questions

Did the opinion treat the laboratory as reselling the repair materials?

No. On the stated facts, it treated the laboratory as the consumer of those materials.

What facts supported that treatment?

The materials were insignificant in value compared with the repair labor, and no separate materials charge was made.

What amount did the opinion say was taxed?

The cost price of the materials used in the lump-sum repair work.

Verbatim support

From the official November 3, 1950 letter:

This rule appears applicable to repairers of dentures by dental laboratories and we, therefore, regard such laboratories as consumers of materials used in making such repairs.

The tax will, accordingly, apply to the cost price of the materials used in the repair work for which the laboratory makes a lump-sum charge.

STATE OF CALIFORNIA

STATE BOARD OF EQUALIZATION

November 3, 1950

Mr. C--- L. C--XXXX --- Avenue

Re:

SR --- XX-XXXXXX

Dear Sir:
This is in answer to your letter of October 31 in which you request an opinion with respect to the application of the State sales tax to repairing and relining of dentures by dental laboratories, which you may publish in the bulletin of the California Dental Laboratory Society. The application of the State sales tax to charges for repair operations and to materials furnished in connection therewith is governed by Sales and Use Tax Ruling 26, copy enclosed. As indicated by the second paragraph of said ruling, if the value of the materials used in repair work is insignificant in relation to the charges for labor performed and a separate charge is not made for such materials, the repairman is regarded as the consumer of the materials. This rule appears applicable to repairers of dentures by dental laboratories and we, therefore, regard such laboratories as consumers of materials used in making such repairs. The tax will, accordingly, apply to the cost price of the materials used in the repair work for which the laboratory makes a lump-sum charge. Very truly yours,

R. G. Hamlin
Associate Tax Counsel
