I am in the process of retiring from the military (1 Jan 2024), establishing residency in TX, and starting a new civilian job (Nov 2023). Between Nov 2023 and December 2023, I will have two income streams (civilian employer & military pay) plus my spouse's full-time salary. Thus, for CY23, how do we calculate how much Federal Income Tax Withholding (FITW) to ensure against under paying?
Commencing 1 Jan 2024, I will have military retirement pay, civilian employer pay, and my spouse's full time-time salary. Thus, I have the same question as above.
