The charge is on every person which includes the assessable entities as enumerated in the provisions of the Income Tax Ordinance 1984
The income taxed is that of the income year and not of the assessment year.

The ordinance, although a permanent enactment but the liability of tax does not arise until the annual Finance Act is passed (Kamakhya Narayan Sing v. C.I.T I.T.R. 683). It has been observed in the case of (Maharaja of Pithapurum v C.I.T 1945 I.T.R.221,223-4) that is Ordinance (Act) “has no operative effect expect so far as it is rendered applicable for the recovery of the tax imposed for a particular fiscal year by a Finance Act” but Sec.183 of the Ordinance provides that if on the first day of July in any year provision has not been made by any Act for the charging of income tax for that year, the provision in force in the preceding year or the provisions proposed in the bill then before Parliament, whichever is more favourable to the assessee, shall apply until the new provision becomes effective.

Ltd. V. C.I.T I.T.R 328).

Since under this Ordinance tax is levied on the actual income of the income year, the facts must be taken as they existed during the income year, therefore, it is immaterial whether the source on income is actually existing or it is discontinued in the assessment year. (Muthappa Chettiar v. C.I.T I.T.R. 311)

are immaterial in assessing the profits of that
year” (Sir Kikabhai Premchand v.C.I.T.[1953] 24
I.T.R. 506 (S.C. of India) unless there is a
statutory provision in contradiciton . Sec. 38 of
the Act is contradiction allowing business loss to
be carried forward.

Sec. 17 of the Act defines the whole range of total income. The underlying principle of this section is to make the chargeability of income depending upon the locality of receipt or accrual. Asseessees are divided into two categories, (a) resident and (b) non resident. Resident and non resident have been defined in Sec. 2(55) and 2(42) respectively. This section defines the extent of total income with reference to the residence of an assessee, in other words the incidence of tax depends upon and is determined by the residential status of an assessee . A resident assessee is charged with more tax than a non resident assessee due to entitlement of exemptions which is not allowable to a resident assessee. The incidence of tax is higher in the case of a resident assessee and less in case of a non resident.

16. Fundamentals of Taxation Charge of Income Tax Test of Residential Status of an Assessee.
The status of residency of an assessee is determined by the duration of his
stay in Bangladesh during an income year and such determination be be
made with reference to each income year. The finding of residence during
one year would not warrant the assumption that the assessee was
residence in the next. (Wallace Bros. & Co. Ltd. V. C.I.T T.R. 39,44)
The required say of an assessee in Bangladesh is alternative, not
cumulative. Each of the two tests requires the personal presence of the
assessee in Bangladesh. To summerise an assessee will be considered as
resident if
He stays total 182 days in Bangladesh in a particular accounting year or
He stays Bangladesh minimum 90 days in a particular accounting year provided that the aggregate stay during four years preceding the current accounting year should not be less than 365 days.

year then the assessee shall be
considerd non resident during that
corresponding assessment year.
