Accounting
A taxpayer’s taxable year is the same as the taxable year for federal tax purposes. If a taxpayer’s taxable
year is changed, or the method of accounting is changed for federal tax purposes, then the taxable year
Period
and method of accounting shall be similarly changed for Kansas tax purposes.

Enclose with Form K-120S:

Credit schedules and the required attachments to support pass-through activities.
An organizational chart showing all partnerships/S Corps and taxable entities that have income
that flows into this entity or flows from this entity.
Be sure to keep copies of all tax documents associated with your return as KDOR reserves the right to
request additional information as necessary.
Extension of
If you are unable to complete your return by the filing deadline, you may request an extension of time to
file. If you filed federal form 7004 with the Internal Revenue Service for an extension of time, enclose a copy
Time to File
of that form with your completed K-120S to automatically receive a five-month extension (for Partnerships)
or a six-month extension (for S-Corporations) to file your Kansas return. Kansas does not have a separate
extension request form. If you are entitled to a refund, an extension is not required in order to file the return
after the original due date.
Important—An extension of time to file Form K-120S does not extend the time for filing a partner’s or
shareholder’s Kansas Individual Income Tax return (Form K-40).
Business
Taxpayers may elect to have all income derived from the acquisition, management, use, or disposition
of tangible and intangible property treated as business income. The election is effective and irrevocable
Income
for the taxable year of the election and the following nine taxable years. The election is binding on all
Election
members of a unitary group of corporations. To make this election, an entity must file Form K-120EL with
KDOR within the time limits established by law for its filing situation.
An entity not previously doing business in Kansas that intends to make this election for its initial
year of business must file Form K-120EL within 60 days after filing the articles of incorporation or
application for authority to engage in business with the Kansas Secretary of State.
For an entity currently doing business in Kansas, the election must be filed on or before the last
day of the tax year immediately preceding the tax year for which the election is made.
Form K-120EL must be sent separately from the K-120S return.
Adjustments
Kansas income tax law provides that partners receiving income from a partnership or corporation may
be required to make certain adjustments to their share of the entity’s income included in their individual
and Other
federal income tax return in order to properly determine their individual Kansas adjusted gross income.
Information
This modification can only be made from information available to the partnership, thus it is necessary that
each partnership notify each partner of his share of the adjustments. In addition to the adjustments,
to Partners
information regarding income not included in ordinary partnership income must be given to each partner.
NOTE: Each partner or shareholder should be notified of the gross of such income received by the
partnership or corporation, each partner’s or shareholder’s share of such income, the total adjustments
applicable and each partner’s or shareholder’s share of such adjustment.
Information given to the partners receiving income should also include the partner’s share of the
Kansas and everywhere property, payroll and sales factors of the partnership making the distribution. This
information is necessary so the partner receiving the distribution can include those factors with their
Kansas and everywhere property, payroll and sales factors in order to properly apportion income to Kansas
in their returns when filed.
Amended
You must file an amended Kansas return when an error was made on your Kansas return or there is a
change (error or adjustment) on another state’s return or on your federal return.
Returns
To amend your Kansas Partnership or S Corporation return, mark the “Amended Return” checkbox on the
front of the K-120S and insert the changes on the return. Include a copy of the other state’s amended return or
a copy of the IRS amended return or Revenue Agent’s Report or adjustment letter showing the adjustments.
AMENDED FEDERAL RETURN: If you are filing an amended federal income tax return for the same taxable
year as your Kansas amended return, enclose a complete copy of the amended federal return and full
explanations of all changes made on your amended Kansas return. If your amended federal return is
