Last July 4th
, 2014, was published in
the Federal Official Gazette, the
Second Resolution that Amends
the 2014 Mexican Tax Rulings
(henceforth Second Resolution).
This document is intended to
inform in general terms, the
relevant aspects in connection with
the provisions related to the
obligation to keep and deliver to
the Tax Administration Service
(SAT by its acronym in Spanish)
the accounting in electronic media,
without including a wide analysis of
it; therefore, it should be needed to
review the specific effects and
consequences, case by case.
Through the Second Resolution,
were added rules establishing
certain requirements and
procedures to follow in order to
comply with the provisions of the
Federal Tax Code and its
Regulations, for those taxpayers
required to keep accounting, jointly
liable taxpayers, or third parties
related to them (except those that
use the tool included in the SAT’s
web page named "Mis cuentas").
Accounting in electronic media
It is established that taxpayers
mentioned in the previous
paragraph should register their
accounting using electronic systems
to generate XML files that contain,
in general terms, the following:
I. Chart of accounts used during
the period, to which should be
added a field with the grouping
code of accounts established by the
Tax Administration Service (SAT
by its acronym in Spanish), for such
purposes.
II. Trial balance including
beginning balances, movements of
the period and ending balances of
each account regarding assets,
liabilities, capital, profits and losses,

purposes are included, will be subject to the following:

Release of information by authority requirement
Additionally, a rule was added, which states that when the tax authority requires accounting information in the
exercise of its power of inspection or when requested as a requirement for the submission of a refund or offset,
or required by the tax authorities in order to solve the source of refunds, taxpayers are required to submit the
electronic file of the generated policies, as well as the acknowledgments receipts corresponding to the rest of the
information.
Likewise, when balances in favor for prior periods are offset, in addition to the policies of the period under
compensation, the file that corresponds to the period in which the balance in favor was originated and
submitted to be offset, should be given only once, as long as it is the month of July, 2014 or subsequent and
until terminated the remaining balance to be offset that corresponds to such period or its refund is requested.
Failure to have the acknowledgment of receipt of the information related to the chart of accounts and trial
balances, the taxpayer should carry out the delivery of this information through the Tax Mailbox.
Transitional Provisions
By transitional provisions it is established that the monthly delivery of accounting through the Tax Mailbox, as
well as the one required by the tax authorities, will be applicable for legal entities from the month of July of the
current year; however, the information related to the trial balance, should be sent as follows:
Trial balance of the month Month of delivery

Likewise, if the tax authorities request information on the accounting for the months of July to December, 2014,
regarding the application of refund or offset, the delivery date will be in accordance to that established for the
trial balances.
Meanwhile, the chart of accounts should be delivered to the authority in October, 2014.
