Extends the authority of the county of Columbia to impose an additional real estate transfer tax

This bill extends Columbia County's existing authority to impose an additional real estate transfer tax for two more years, changing its expiration date from December 31, 2025, to December 31, 2027. It directly affects property buyers and sellers within Columbia County who would pay this extra tax during real estate transactions. The key mechanism is a simple amendment to the tax law's expiration date, maintaining the current tax structure without altering the tax rate or eligibility. The bill does not create new taxes or change who qualifies for the tax, only prolonging the current authority. This is a procedural extension of an existing local tax policy.
