An Act amending the act of March 4, 1971 (P.L.6, No.2), known as the Tax Reform Code of 1971, in sales and use tax, further providing for assessment; in personal income tax, further providing for assessment; in corporate net income tax, further providing for assessments; in procedure and administration, further providing for petition for reassessment; and, in general provisions, further providing for petitions for refunds and providing for compromise or adjustment of assessments.

HB 856 amends Pennsylvania's 1971 Tax Reform Code to improve transparency in tax assessment notices. It requires the Department of Revenue to explain adjustments in all assessment notices (affecting taxpayers receiving such notices) and sets a 60-day window for filing reassessment petitions only if notices include these explanations. The bill also adds a six-month deadline for refund petitions when tax credits offset assessments and allows the Department to adjust assessments for clerical errors, documentation issues, or financial hardship without requiring taxpayer appeals. These changes streamline administrative processes but do not alter tax rates or create new tax obligations.
