The strike, bringing school closures and a halt to garbage collection for millions of Israelis, also complicates a bid to pass a 2023-2024 state budget.
The dispute is over a proposed fund that would dip into commercial property taxes collected by municipalities.
More than 70 cities, including commercial hubs Tel Aviv and Haifa that will be paying more heavily into the property tax fund, joined the strike.
Finance Minister Bezalel Smotrich said he would not give in and that the property tax fund would be passed as part of legislation for the 2023-2024 budget.
Parliament has already given its initial approval for the 2023-2024 budget but it still needs to pass two more votes.
