​Account Information

​The best way to access company account numbers is via Kentucky One Stop Business Portal.  Another way would be if the interested party is listed on form 20A100 (Power of Attorney/Declaration of Representative) on file with the Department of Revenue. This info may be provided via phone contact but the caller would need to identify as the business owner, tax preparer and/or representative, and be prepared to provide material information to cross-reference in order to establish caller identification. The Department of Revenue is limited on the information that can be given out over the phone because of confidentiality.

​Contact the Division of Corporation Tax at (502) 564-8139 and provide the Corporate/LLET Account Number or FEIN. 

​All required tax returns must be filed and paid from the date of incorporation or organization.  Tax notices must be paid in full, unless the notice(s) are still within the protest period, have been timely protested, or are under a valid pay agreement with the Division of Collections. 


​Business Closing/Ceased Operations

​When the last return is filed, clearly mark the box as a "FINAL" return. For the return to be accepted as final, the corporation should attach a balance sheet reflecting zero assets. The final Corporation Income and Limited Liability Entity taxes must be paid with the return. The corporation must also timely close their account with the Secretary of State by filing Articles of Dissolution.

​To find out the status of your refund request, please contact the Division of Corporation Tax at (502) 564-8139 and provide the Corporate/LLET Account Number or FEIN along with the form year in which the refund was requested.

​The tax imposed by KRS 141.0401 is a tax imposed on those entities with limited liability in the state of Kentucky and not an income tax. Therefore, the Limited Liability Entity Tax (LLET) paid is not an add-back to determine Kentucky taxable income; it is deductible for Kentucky and federal purposes.

​No, KRS 141.010(13)(d) states that any deduction allowed under Chapter 1 of the Internal Revenue Code must be reduced by the expenses related to the general stewardship of the assets that produced the non-business or nontaxable income. Actual expenses are preferred; however, several approved formulas can be found in Regulation 103 KAR 16:060.

​Yes, when a company is registered with the Secretary of State, they are considered to be "doing business" in the state of Kentucky per KRS 141.010(7)(a) and are therefore required to file a tax return for the year that the company registers. A foreign corporation registered with the Secretary of State may not be required to file a return if they did not actively conduct any business during the year. The Department of Revenue may ask for a signed statement from a responsible party in the business to confirm no activity in Kentucky during the given tax year. Foreign corporations register because there may be potential for business in the Commonwealth of Kentucky.

​A name reservation allows a company to pay a fee to reserve a name before starting a business. No legal entity exists at the point that a name reservation is done; therefore, the company is not registered with the Secretary of State or considered to be "doing business" in the state of Kentucky per KRS 141.010(25)(a) and does not need to file a return with the Department of Revenue. If and when a legal entity is incorporated or organized in Kentucky under that reserved name, it will have a filing requirement with the Department of Revenue.

​Yes, a taxpayer should file a return on the correct form type and mark it "AMENDED" to void the tax return filed on the incorrect form type. Taxes paid with the incorrect form type may be transferred to the correct form type upon written request by the taxpayer.

​Yes. A Homeowner's Association may owe Kentucky income tax even though the association may not owe federal Corporation Income Tax (federal Form 1120-H).  The company may owe Kentucky Corporation Income Tax because of the differences between federal and Kentucky tax law. 


​Nonprofit/Exempt

​A copy does not have to be filed with the Kentucky Department of Revenue. However, the Kentucky Attorney General's Office requires a copy of Form 990 to be filed with its office for any non-profits soliciting in the state. (See KRS 367.657)


​Nonresident Withholding/Composite Returns

​Yes, per KRS 141.206(16)(a), if the shareholders agree to be included in the composite return and have been exempted from nonresident withholding. Estimated payments are required if the tax liability is expected to be $500.00 or more.

​Per KRS141.206(16)(d) a pass-through entity shall deliver to the Department a return upon a form prescribed by the Department. The form to be completed is Kentucky Form 740 NP-WH. 2009 is the first year for the use of Kentucky Form 740 NP-WH as a composite return. Any returns filed on Kentucky Form 740-NP, Kentucky Income Tax Return Non-Resident or Part-Year Resident, will not be accepted.

​Yes, the composite return is a return filed on behalf of nonresident individual partners, members or shareholders. Per KRS 141.300, if the tax liability for an individual partner, member or shareholder can be expected to be over $500, then estimated payments are required.  Interest and penalty bills will be issued for underpayment of estimated payments.

Individual Partner, Member or Shareholder estimated installment payments:

1st installment: due the 15th day of the 4th month of the taxable year end
2nd installment: due the 15th day of the 6th month of the taxable year end
3rd installment: due the 15th day of the 9th month of the taxable year end
4th installment: due the 15th day of the 1st month following the close of the taxable year end

Note: If the filing/payment date falls on a Saturday, Sunday or a legal holiday, the filing/payment date is deemed to be on the next business day. 

​Opening/Starting a Business in Kentucky

​You may open an account through the Kentucky One Stop Business Portal to register your business with the Kentucky Department of Revenue and get all of the tax accounts you need for your particular business.  You may also file Kentucky Form 10A100, Kentucky Tax Registration Application. 


​Other Form Questions

​No.  Per KRS 131.180(2), extensions are for filing the return at a later time up to six months, but payments are due on or before the original due date of the taxpayer's return.

​Yes, Kentucky Form 20A100 can authorize certain professionals to represent taxpayers with the Department of Revenue.  Federal Form 2848 is also accepted.

At this time, the Kentucky Department of Revenue does not require federal Form 1099 'state' copies to be filed for corporation tax purposes. It is recommended that copies be kept in the taxpayer's records should the Department need to make reference to them.

NOTE:

  • Federal Form 1099 may be required for Individual Income Tax filing if there is Kentucky withholding claimed on the Kentucky individual return.
  • Federal Form 1099 with state withholding should be submitted to W-2 Processing using a Transmitter Report for Filing Kentucky W2/K2, 1099 and W2-G statements.


​Statutes and Regulations

​Taxpayers can find information on Kentucky requirements in the Kentucky Revised Statutes (KRS) and the Kentucky Administrative Regulations (KAR). Both can be found on the Legislative Research Commission website. Most of the authority for income taxation may be found in KRS Chapter 141 and KAR Title 103.
