Get Ready for Tax Season in Kansas City: A December-to-April Game Plan

Tax season in Kansas City does not start in April. For anyone with a small business, a side gig, or a cross-state commute, the smoothest filings begin in December. Here is a month-by-month plan.
December: last chance to change the numbers
Estimate your profit and decide on any year-end purchases or retirement contributions
Open a Solo 401(k) now if you want one for this year
Make charitable gifts before December 31
January: the deadline month
January 15: fourth-quarter estimated payment
January 31: 1099-NEC forms to contractors, W-2s to employees, and payroll filings
Employers in Kansas City, Missouri: city earnings tax withholding filings
Close and reconcile your books for the year
February: gather and organize
Collect every W-2, 1099 and 1098 as they arrive
Total your mileage and home office expenses
Commuters across State Line Road: confirm your W-2 splits Missouri and Kansas wages correctly (8 questions commuters ask)
March: file business returns and decide on S corp
Partnership and S corporation returns are generally due mid-March
Form 2553 for a new S election is generally due by about March 15
April: file, pay, and start the new year right
File federal, Missouri or Kansas, and city returns (or extensions)
Remember an extension extends the time to file, not the time to pay
Make the first quarterly estimated payment for the new year
