Should You Prepay Kansas State Income Tax Before Year-End?

Should you prepay Kansas income tax image

This year, because of significant changes in the Kansas tax laws, taxpayers should take a hard look at whether to pre-pay 2017 state income taxes before Dec. 31. The Kansas Legislature’s rollback of 2012 state income tax cuts reinstates state income tax on non-wage business income for sole proprietorships, farming and rental activities, and pass-through entities, such as partnerships, LLCs and S corporations – so taxpayers with these types of income may once again owe Kansas income tax. This group includes many manufacturing, wholesale and distribution entities and their owners.

The State of Kansas does not require adjustments to 2017 estimated quarterly income tax, as long as the tax liability is paid by April 15, 2018. However, proposed federal tax reforms complicate the pre-payment decision.

  • The current federal tax reform proposal would eliminate the state income tax deduction for individuals in 2018. If this passes, it may make sense to pre-pay Kansas income tax in 2017.
  • BUT, if a taxpayer is subject to the alternative minimum tax (AMT) in 2017, it may limit the amount that should be pre-paid.

Bottom line – this is a critical year for Kansas taxpayers to review their situation with a tax professional well before year-end, to evaluate how best to manage and mitigate tax liability in the current environment. Keep an eye on federal tax reform and set up an appointment with a tax advisor as soon as possible.
