AUGUSTA – State House celebrations over enactment of a major property tax relief bill have obscured a lack of progress on a half-dozen constitutional amendments that are closely linked to the successful legislation.

The amendments – including one submitted by Gov. John Baldacci – remained bottled up in the House, some lacking sufficient support to win final passage so they can be sent to voters and one all but dead.

Sen. Joseph Perry, D-Bangor, said Wednesday he’s prepared to send a lifeline to the bills and send them to the Taxation Committee he co-chairs in order to keep them from dying on the floor.

The bills were relegated to the shadows last week when Baldacci, with great fanfare, signed a bill to increase school subsidies, impose local and state government spending caps and broaden existing property tax programs.

Baldacci said the bill would mean average savings of $207 to property taxpayers in two years.

A proposed constitutional amendment that accompanied Baldacci’s tax relief bill, after extended committee discussion during the last several weeks, remained unfinished Wednesday. The bill seeks to allow municipalities to limit changes in tax rates applying to properties that remain principal residences.

When it finished its work on Baldacci’s property tax measure, the Joint Select Committee on Property Tax Reform also sent five other proposed amendments to the floor for review. Perry said they were designed by the committee as “simply tools, local options” to allow communities to tailor tax relief programs to their needs.

Those bills would allow the Legislature:

. To let municipalities adopt tax rates on secondary residential property that are as much as 25 percent higher than the rate for other property.

. To permit or require municipalities to limit the rate of increase in the taxable value of small-business land.

. To allow municipalities to adopt property tax assistance programs that reflect residents’ ability to pay.

. To let municipalities exempt from property tax a portion of the value of homesteads.

. To assess waterfront land used for commercial fishing activities based on the current use of that property. Similar tax treatment is allowed for farms, open space and woodlands.
