Estimated quarterly taxes

[bbq2]

I am retired, filing single in the State of Kansas.  I have the maximum withholding taken from my social security income.  I do the maximum to also cover investment income.  Last year, I did a Roth conversion that placed me over the threshold for social security to owe income tax in Kansas.  This year, I will do a smaller Roth conversion that will keep me under the threshold, so I don't anticipate owing any State tax.  Is there any reason that I would have to pay estimated quarterly taxes in this scenario?  Thank you.

According to the state of Kansas Department of Revenue: 

You must make estimated tax payments if your estimated Kansas income tax after withholding and credits is $500 or more and your withholding and credits may be less than the smaller of:
a) 90% of the tax on your tax return for tax year 2023; or
b) 100% of the tax shown on your 2022 tax return. 

Keeping this rule in mind your need to pay estimated taxes is dependent on your income from both years. I always advise to consider how much you owed in the previous year as a good guide for the next year unless you know EXACTLY how much the change will be. The good thing is that if your total amount owed to Kansas was under $500 you do not need to make estimated tax payments!

If you will be under the threshold for your social security to be taxable in Kansas for 2023 Estimated taxes may not be required but if you investment or other income  is more than you had anticipated , you could have state and federal  tax owed for 2023. I recommend you review your projected 2023  income from all sources in late fall of 2023 to see if your projected income is still close to what you have calculated to  avoid paying any state tax.
