We all know that we have to submit income tax return in November of each year in Bangladesh. There are so many individuals who do not have any knowledge of how to calculate taxable income, what investment allowance indicates, how to prepare and submit a tax return. Imagine that you are a business journalist of a renowned daily newspaper of Bangladesh and the editor wants you to write an article explaining the detailed insights of preparing a tax return file of an individual having income from salary only. The main objective of such an article is to literate people with no knowledge of taxation and allow them to prepare tax returns by themselves. You should cover all the points including calculation keys, rates, date concerns, and submission process that a salaried individual requires to know before preparing his/her return.

Prepare an article for the newspaper and give a suitable title as well.
