BATON ROUGE - While Louisiana's lawmakers continue to disagree on taxes, the House and Senate also are at odds over how to balance the budget with the dollars they do raise.

The fissure risks causing a problematic time crunch in the special legislative session, with a week remaining.

The dispute centers on how Louisiana develops the income projections used for budgeting.

Budget bills must start in the House. But House leaders say they don't want to craft a plan to spend any new tax dollars until the state's income forecasting panel, called the Revenue Estimating Conference, formally recognizes the money as available for spending.

Senate leaders say formal recognition of the tax dollars can happen after the special session ends and before the July 1 start of the new budget year.
