Qatar Tax law provides that any
business activity carried out in Qatar will be subject
to tax. An "activity" has been defined as
any occupation, profession, service, trade or the
execution of a contract or any other business for
the purpose of making profit. Income tax is levied
on partnerships and companies operating in Qatar whether
they operate through branches or in partnership with
foreign companies.
The Gregorian calendar is used for
Qatar income tax purposes, but a taxpayer may apply
to prepare his financial statements for a twelve-month
period ending on a day other than 31 December. The
first accounting period may be more or less than twelve
months, but it should not be less than six months
or more than 18 months. A taxpayer should keep his
accounting records in Qatari Riyals unless permission
is obtained from the tax administration for them to
be kept in a foreign currency.
