AIOU Solved Assignment Code 456 Solved Questions & Model Answers

To assist students who wish to understand the conceptual depth required for university examinations, we have transcribed verified model solutions to key assignment questions below:

Assignment No. 1 – Question 1

Question: State the statutory criteria for determining whether an individual is a Resident in Pakistan for a tax year under Income Tax Ordinance 2001.

Model Answer:

Under Section 82 of the Income Tax Ordinance 2001, an individual is classified as a Resident Individual for a tax year if they meet either of the following conditions: 1. The individual is physically present in Pakistan for a period of, or periods aggregating to, 183 days or more in the tax year (July 1 to June 30); or 2. The individual is an employee or official of the Federal Government or a Provincial Government of Pakistan posted abroad in that tax year, irrespective of days spent physically in Pakistan. Determining residency is pivotal because resident taxpayers are taxed on their worldwide income, whereas non-residents are taxed strictly on Pakistan-source income.

Assignment No. 1 – Question 2

Question: Explain the tax treatment of Salary Perquisites: Medical Allowance, Conveyance for personal use, and Provident Funds.

Model Answer:

Under Income Tax rules: 1. Medical Allowance: If actual medical expenditure reimbursement is provided under employment contract, the reimbursement is exempt up to verified limits, but cash medical allowance is exempt up to 10% of basic salary. 2. Conveyance Perquisite: If a motor vehicle is provided partly for personal and partly for business use, 5% of the total acquisition cost (or fair market lease value) is added to taxable salary income; if provided exclusively for personal use, 10% is added. 3. Recognized Provident Fund: Employee contribution is part of basic pay (already taxed), employer contribution is exempt up to 10% of basic salary plus DA or Rs. 150,000 (whichever is lower), and interest credited is exempt up to one-third of salary or 16% interest rate.

Assignment No. 1 – Question 3

Question: Distinguish between Zero-Rated supplies and Exempt supplies under the Sales Tax Act 1990.

Model Answer:

Under the Sales Tax Act 1990: 1. Zero-Rated Supplies (Fifth Schedule): Goods are charged to sales tax at the statutory rate of 0%, but the registered manufacturer or exporter is legally entitled to claim full Input Tax Adjustment / Refund for taxes paid on raw materials and utilities used in production. 2. Exempt Supplies (Sixth Schedule): Goods are entirely outside the sales tax charge; however, the manufacturer cannot claim input tax credit or refund on purchase inputs, meaning the tax paid on inputs becomes an unrecoverable business expense absorbed into product cost.

Assignment No. 2 – Question 1

Question: Enumerate five business deductions that are explicitly inadmissible under Section 21 of the Income Tax Ordinance 2001.

Model Answer:

Section 21 disallows: 1. Any salary paid in cash exceeding Rs. 32,000 per month without routed through corporate bank accounts. 2. Any expenditure exceeding Rs. 250,000 incurred under a single account head paid in cash rather than banking instruments. 3. Any payment from which statutory Withholding Tax was legally deductible but was not withheld or remitted to FBR. 4. Fines or financial penalties levied for violation of any law or regulation. 5. Any personal or domestic expenditures of the taxpayer disguised as business costs.

Assignment No. 2 – Question 2

Question: Outline the appellate hierarchy available to a taxpayer dissatisfied with an assessment order passed by an FBR Commissioner.

Model Answer:

The statutory appellate hierarchy comprises: 1. Commissioner Inland Revenue (Appeals): An appeal must be lodged within 30 days of the assessment order. 2. Appellate Tribunal Inland Revenue (ATIR): The final fact-finding judicial tribunal; appeals against CIR(Appeals) orders must be filed within 60 days. 3. High Court: Tax references on substantial questions of law are heard by a divisional bench of the respective High Court within 90 days of an ATIR decision. 4. Supreme Court of Pakistan: Final constitutional appeal through leave to appeal.
