This document discusses Pakistan's Self Assessment Scheme for income tax assessment year 2001-2002. Some key points: - The scheme allows taxpayers to self-assess their income tax as long as certain conditions are met, such as fully paying tax and filing on time. - Certain types of returns are not eligible for self-assessment and will undergo a full audit, such as those with declared losses or lump sum additions. - Eligible returns must include detailed documents supporting income sources like business financial statements, salary certificates, property tax payments. - 20% of returns will be randomly selected for a full audit to verify self-reported income and tax payments. Assessors can make adjustments if deficiencies are found
