The plaintiffs, owners of real property which was leased to the defendant F. W. Woolworth Co. (Woolworth), sought a declaration of the “rights and responsibilities of the parties concerning payment of the 1972 real estate taxes,” as well as an order compelling Woolworth to pay them the amount of such taxes.
The plaintiffs complaint was referred to a master who filed a report with the Superior Court. In his report the master found for the plaintiffs. A Superior Court judge adopted the master’s report and entered judgment for the plaintiffs. The defendant timely filed its notice of appeal. The Appeals Court affirmed the judgment.
The facts as found by the master are as follows. The defendant has occupied the premises since 1925 under a lease executed in April of that year. The lease contained the following provision: “The Lessee and its successors hereby covenants with the lessors, their heirs, and assigns that it, and its successors shall pay all taxes, (except Federal and State Income Taxes, and Betterment Taxes) Water Rates, Fire and Plate Glass Insurance on said premises, or any part thereof.” The plaintiffs or their predecessors in interest entered into four modifications and extensions of the original lease. At all times the tax clause of the lease was operative, and it remained in effect until the tenancy was terminated under the lease on April 30, 1972. Prior to the termination of the lease, the real estate taxes for 1972 had been assessed. See G. L. c. 58, § 3.
It is a well settled principle that clauses in leases by which a tenant covenants to pay real estate taxes require the tenant to pay the taxes for the entire year if the taxes are assessed during the period of tenancy.

v.
American Woolen Co.,
Woolworth argues, however, that the provisions of the lease requiring proration of the rent on termination of the lease by the option granted under the contract, a lengthy notice period of 360 days before termination, and removal *355 of effects prior to termination indicate that the parties intended that the obligations of the defendant would cease when its occupancy ended. Thus, Woolworth contends that the tax clause should be interpreted as requiring the tenant to pay only the taxes allocable to its period of occupancy during 1972. The tax clause contained in the lease, however, has a specific, well settled meaning. Koshland v. American Woolen Co., supra. Baker v. Horan, supra at 420. Welch v. Phillips, supra at 268. Paul v. Chickering, supra at 267. The parties are bound by this clause, which was not altered by any of the modifications of the contract and which carries a recognized legal interpretation. When a provision with a well established meaning is contained in a contract, that clause, rather than any supposed intentions of the parties gleaned from analysis of other provisions, determines the obligations of the parties.
Woolworth further argues that it is inequitable to interpret the tax clause of the 1925 lease as requiring tenants to pay taxes for the entire year when the taxes have been so increased as to equal almost the amount due for rent. Once again, we note that the clause used in the lease has a well settled meaning. The lease involved in the present case was modified four times, the last time being in 1968, only three years before notice of termination was given. At the time of the modifications the increase in taxes since 1925 must have been apparent. If the defendant had desired to modify the tax clause in the lease, it could have bargained for such a change at the times of these modifications. See

Rice,
Finally, Woolworth contends that the erosion of the doctrine that covenants in leases are independent requires that the obligations of tenants be measured by occupancy. Woolworth argues that this development in the law supports its position that it is liable only for the taxes allocable to the period of its occupancy. While there is a developing tendency to treat some lease covenants as interdependent, no general rule that all obligations of tenants are to be measured by occupancy has evolved. Rather, the courts have focused their attention on the interdependence of the tenant’s duty to pay rent and the landlord’s duty to maintain premises suitable for the tenant’s use. See

v.
Hemingway,
What we have said disposes of the issues presented in this case. However, in considering the application of the general principle governing interpretation of provisions requiring payment of taxes, we have concluded that, because of changes in the nature and conception of leases, interpreting such clauses as requiring payment only of the portion of taxes allocable to the period of tenancy would now be in accord with the expectations of the contracting parties. See
Tristram’s Landing, Inc.
v.
Wait,
Provisions requiring tenants to pay taxes have had an unambiguous and long settled interpretation. Such provisions were presumably included in leases in reliance on this interpretation. Therefore, tax clauses contained in leases now in existence will be interpreted in accordance with this long-standing construction. However, for tax clauses contained in leases executed after the date of this opinion, we adopt the following rule. A provision in a lease requiring the tenant to pay taxes will be interpreted as requiring the tenant to pay the amount of taxes allocable to the period covered by the lease. The parties, of course, may agree that *358 the tenant is required to pay the taxes on the property for the entire year, whether or not the lease covers that whole period. However, such an obligation on the part of the tenant must be clearly expressed. This rule is in accord with the expectations of the parties and places the burden on the landlord to give clear notice to the tenant if the tenant is to be obligated to pay taxes for a greater period than he would otherwise assume.
Judgment of the Superior Court affirmed.
