Common questions
- Is a return needed if APIT covers my salary?
- If salary is genuinely your only income, APIT can settle the liability. Add bank interest, consultancy on the side or rental income and a return becomes necessary to bring them together at the right rate.
- How is consultancy alongside a salaried job taxed?
- As business income on Schedule 2. It stacks on top of your salary for slab purposes, which means it is usually charged at your highest marginal rate — worth estimating before you take the work.
- What is the personal relief for Y/A 2025/2026?
- Rs. 1,800,000, applied once across all your income under the Inland Revenue (Amendment) Act, No. 02 of 2025. It is not per source and not per employer.
