Modifies provisions relating to income tax deductions for private pensions

HB 1762 modifies Missouri's income tax rules for retirement benefits, primarily affecting taxpayers receiving private pension income. It increases the maximum deductible amount for retirement benefits from private sources: $6,000 annually for tax years 2002-2026, rising to $12,000 annually starting in 2027. The bill specifically includes 401(k) plans, IRAs, and other private retirement arrangements (but excludes Roth IRAs) in the deduction calculation. Deduction limits apply based on filing status (e.g., single, married filing jointly) and income thresholds, with higher limits for lower-income taxpayers.
