I currently work for a company HQ in Denver, I'm moving from NYC to Denver on September 8th, working for the same company. How will my state and local taxes be calculated for January to September in NY state and how will my September to December earnings be taxed by NY and CO states?
For example: If my income from Jan - Sept 8th is $100K and Sept 9th - Dec is 200K, what will my state tax withholdings be and what state and local taxes will I owe for NY state and CO for tax year 2020?
Thanks
