Ott, J.

— Prior to May 18, 1962, Marshland Flood Control District of Snohomish County (hereinafter referred to as the district) requested contractors to bid upon the construction of a proposed flood control and drainage water discharge facility in the Marshland, watershed. Prospective bidders were furnished a form which included instructions. One of the instructions in the form provided, *inter alia:*

> *462(c) . . . As required by Clause 38, General Provisions, unit prices shall include all applicable Federal, State and local taxes, including State retail sales taxes.

S. S. Mullen, Inc., a corporation (hereinafter referred to as Mullen), was the successful bidder for a total unit price of $923,925.60. Clause 38 of the “General Provisions” of contract No. M-FCD-4, executed May 18, 1962, was as follows:

> Except as otherwise provided, contract unit prices include all applicable Federal, State and local taxes.

In addition, the bid schedule attached to the contract contained specifications (c), *supra.*

Mullen performed its contract, and progress payments were made by the district from time to time until the full contract price was paid, each voucher containing the statement, “Payment does include *4%*Sales Tax under provisions of Contract M-FCD-4.”

After the work was completed and accepted, Mullen requested payment of the retained percentage which had been withheld by the district. The district refused to remit the retained percentage until Mullen furnished a receipt from the State Tax Commission for payment of the 4 per cent sales tax. Mullen paid the tax, furnished the receipt to the district, received the retained percentage, and instituted this action to recover $32,966.72, the amount the State Tax Commission had computed as the applicable sales tax due. The complaint alleged, *inter alia:*

> That the contract above referred to provides in part:

> “38. Federal, State and Local Taxes.

> Except as otherwise provided, contract unit prices include all applicable Federal, State and local taxes.”

> That said clause referred to Federal and State income and business taxes and State Sales Taxes on materials and supplies used in the performance of the contract which the contractor is required to pay pursuant to Washington Law and published rules of the Washington State Tax Commission. That said clause did not refer to the Washington State Retail Sales Taxes which the prime contractor is required by RCW 82.08.050 to collect *463from the purchaser. That RCW 82.08.120 forbids absorption of the tax by the seller and RCW 82.08.050 makes the tax imposed a debt from the buyer to the seller until the same is collected from the seller.

The district’s answer alleged, *inter alia,*that the specifications to bidders required that the sales tax be included in the unit price; that the contract, in furtherance thereof, provided that all applicable federal, state, and local taxes, including the retail sales tax, had been included in the unit price bid, and that, by the payment of the total unit price, the district had paid to Mullen the tax it was required to pay by law, and which Mullen was required by law to collect.

The district’s motion for summary judgment was predicated upon requests for admissions and answers thereto, and affidavits in which factual matters substantially as above set out were admitted. The court, relying upon the rule announced in *Kaeser v. Everett,*47 Wn.2d 666, 289 P.2d 343 (1955), granted summary judgment and dismissed Mullen’s cause of action with prejudice.

From the judgment of dismissal, Mullen appeals.

Mullen first assigns as error the trial court’s “holding that the Washington sales tax on the total contract price could legally be included in the unit prices of the contract.”

We agree with the trial court that the decision in *Kaeser v. Everett, supra,*is controlling, and that, under the circumstances here present, RCW 82.08.120 does not prohibit a contractor’s adding to the unit price of his bid the amount of the sales tax, when the consumer requests him to do so.

Mullen next assigns error to the court’s “holding that the clauses in the contract and the bid schedule concerning taxes were not ambiguous.”

The instructions to bidders and the contract required Mullen to add to its unit price bid all applicable federal, state, and local taxes, including the state retail sales tax. Mullen contends that this provision is ambiguous because the district was required by law to pay the tax in *464question; hence, the tax was not applicable to Mullen. RCW 82.08.120 does place the burden of paying the tax on the district, but places on Mullen the burden of collecting the tax from the district. It is a tax resulting from the performance of the work specified in Mullen’s contract, and is within the purview of *“all applicable*Federal, State and local taxes, including State retail sales taxes,” which the specifications in the call for bids and the contract required Mullen to add to its unit price bid.

We conclude that the contract is not ambiguous in this respect.

Mullen next asserts that the contract is ambiguous, in that the term “applicable” was not defined, and that there was a duty on the part of the district to itemize the taxes which were to be added to the unit price bid.

We find no merit in this contention. The words *“all applicable . . .*taxes” encompass every conceivable tax resulting from the performance of the contract.

Mullen further asserts that the court’s interpretation of the contract requires Mullen to absorb the tax, which is forbidden by RCW 82.08.120.

In *Stoen v. French Slough Flood Control Dist., ante*p. 440, 407 P.2d 963 (1965), we held that a request by a consumer that the sales tax be added to the unit price bid was not violative of RCW 82.08.120, “provided the burden of the tax falls upon the consumer.” We further held that

> Adding a specific tax to a unit price bid does not shift the burden of payment of the tax to the one submitting the bid, and, therefore, does not result in an absorption of the tax by the bidder.

We adhere to the rule announced in the *Kaeser*and *Stoen*cases, *supra,*and hold that the sales tax can legally be included in the unit price bid, when required by the consumer.

Finally, Mullen asserts that a summary judgment should not have been entered in this cause for the reason that there was a disputed issue of material fact, in that Mullen’s affi*465davit alleges that it had not included the tax in its bid and did not understand that it should do so.

Although there may be some disputed issues of fact, they are material to this appeal only if the contract is ambiguous. Since we have found, as a matter of law, that the specifications in the call for bids and the terms of the contract are clear and unambiguous, the disputed factual issues are not here pertinent.

The judgment is affirmed.

All Concur.
