The filing deadline for submitting your 2010 Kansas tax return is April 18, 2011, the same date as the deadline for your federal income tax return. Sometimes, though, you may need a little more time. Kansas is one of the few states that does not require that you file for a state-designated legitimate reason. However, to receive a Kansas extension, you must also file a federal tax extension.http://www.ksrevenue.org/pdf/forms/iiwhatsnew.pdf 

If your extension request is approved for the state of Kansas, you will receive an additional six months to file your state return. This will give you an extended filing deadline of October 18. But any additional tax that is owed to the Kansas Department of Revenue will still be due on April 18. Your extension is merely an extension to file your return, NOT an extension to pay your tax.http://www.ksrevenue.org/pdf/forms/k-40v10.pdf  

To begin your Kansas extension, you will need to gather all of the same information you will use to prepare your Kansas return. This includes the following:

1. Your total earned income for the year - If you are employed, use the total taxable wages reported to you on Form W-2 or Form 1099. If you are self-employed, total your gross earnings received and subtract any eligible business expenses you can claim.
2. Your total unearned income that is also subject to Kansas state tax - Among other things, this will include unemployment compensation, bank interest income, and lottery winnings.
3. The total amount of your state income tax payments made - For employees, this will appear on Form W-2 as state taxes withheld. Self-employed individuals will use the amount of any estimated tax payments made.http://www.ksrevenue.org/pdf/forms/geninst10.pdf 

Since you are required to file a federal tax extension in order to receive a Kansas tax extension, you may wish to consult with tax professional. He or she can help you to calculate your federal adjusted gross income, or AGI, which you will use to start assessing your state tax liability. If you would like to try it yourself, full guidelines regarding the figuring of federal AGI are available on the Internal Revenue Service website.www.irs.gov 

To complete the extension payment voucher, you will also need the following:

1. Your Social Security number
2. Your current mailing address
3. The full name and Social Security number of your spouse, if you will be filing a joint tax returnhttp://www.ksrevenue.org/pdf/forms/geninst10.pdf

Now you will begin calculating your state tax liability. To do this, you need a paper copy of Form K-40 "Kansas Individual Income Tax" return and the form instruction booklet. These forms are available for download on the Department of Revenue website.http://www.ksrevenue.org/pdf/forms/k-4010.pdf 

Begin by entering the amount of your federal adjusted gross income on line 1 of the Kansas form. Stop and read the entire form instructions before proceeding. You will need to pay special attention to the sections dealing with state income adjustments, since you may have received income that is not taxable to the federal government but is taxable in Kansas, or vice versa. Be sure to read the section regarding state tax credits as well, since you may qualify to claim some of these on your return.http://www.ksrevenue.org/pdf/forms/geninst10.pdf 

Make any income adjustments necessary on line 2 of the form and then add or subtract these to calculate your Kansas adjusted gross income on line 3. Deduct the standard deduction for your filing status or your itemized deductions and the total amount of your exemptions to calculate your net taxable income in Kansas on line 7. Consult the tax tables to assess the exact amount of tax due on your taxable income and then enter that amount on line 8 as your tax. Add any extra taxes due to calculate your total tax liability on line 12.http://www.ksrevenue.org/pdf/forms/k-4010.pdf 

Next, subtract all of the state tax credits you are eligible to claim. Then add in any use tax you are subject to. Deduct your state income taxes paid through withholding or estimated tax payments. What remains will be either a balance due on line 33 or a refund on line 40.http://www.ksrevenue.org/pdf/forms/k-4010.pdf

If you are due a refund on your Kansas return, you can stop here. Simply file your state return when you are able and you should still receive your full refund from the department of revenue. But if you owe additional tax, you will need to remit payment before April 18 in order to receive your extension.http://www.ksrevenue.org/pdf/forms/geninst10.pdf 

First, make a copy of your IRS Form 4868 "Application for Automatic Extension of Time to File U.S. Individual Income Tax Return".http://www.irs.gov/pub/irs-pdf/f4868.pdf You will need to attach this copy of your federal extension form to your Kansas state return when you are ready to file it. This will serve to notify the Kansas Department of Revenue that your return is being filed after the date but with an approved extension.http://www.ksrevenue.org/faqs-taxii.htm

Along with attaching your federal extension form, you must also remit at least 90% of your outstanding tax balance before the original filing deadline of April 18 to receive your extension. To do this, you need to complete Form K-40V "Kansas Individual Income Tax Payment Voucher".http://www.ksrevenue.org/pdf/forms/k-40v09.pdf This form is available for download on the Kansas Department of Revenue website or you can request a paper copy by contacting the Department of Revenue by email.http://www.ksrevenue.org/pdf/forms/k-40v10.pdf 

Complete the voucher by entering your full name and your spouse's full name if applicable. Then enter both of your Social Security numbers as well as your current mailing address. Check the box indicating that this is an extension payment and then write in the total payment you are remitting with the voucher. Send the voucher and a check or money order for your payment to the address listed on the voucher instructions.http://www.ksrevenue.org/pdf/forms/k-40v10.pdf Once you remit payment, try to begin your Kansas tax return as soon as possible.
