I don't think It's a matter of choice.
If you move yourself and home goods to a TN residence, for the foreseeable future (or usually planned to exceed at least 6 months).....then you become a TN resident on the date you move into your new residence/home in TN.
Now, taxwise, OH can tax all your OH job wages, both before and after you move to TN, as long as you continue physically working in OH...so no difference there.
,,BUT #1: before you move, OH can also tax all your interest, dividends, and investment income...also any retirement distributions too.
..But #2: after the date you move to TN, OH can no longer assess an income tax on those extra sources of income.
Yes, TTX can handle a part-year tax return for OH, but if it gets too complex for you (when you start allocating what income belongs to OH) then get a local tax preparer to do it for you for whatever year's taxes are involved with your move.

As a practical matter, if you plan to vote in the November election....do NOT move before the middle of November. Once you move, you are no longer a resident of OH and cannot vote there, and if you actually move in the next few weeks before the election, it may be too late to register to vote in TN (that depends on what TN's registration laws are...but some states are shutting down soon)
