What the agreement does for you
- Cross the line from Kentucky into Michigan for work and you keep money you would otherwise lose. The home charge on seventy thousand dollars is $2,332. Michigan would have wanted $2,724 for the same wage. Because the two states have a deal, you pay home only, and $392 a year never leaves.
- It does not stay the same as you earn more. On forty-five thousand dollars the Kentucky bill is $1,457; on a hundred thousand it is $3,382. Michigan would have charged $3,999 at that higher wage. The two states pull apart as the salary rises, which is why this matters more to a senior job than a starter one.
- One piece of paper stands between you and this. Your employer needs the Michigan exemption certificate from you, usually once a year. Without it they must keep withholding Michigan tax from a Kentucky resident. You would then be filing a return there after all.
- Wages earned in Michigan by a Kentucky resident attract $2,332 rather than $2,724 at seventy thousand dollars, the agreement suppressing a differential of $392. ⚠️ That differential — not the work state's gross liability — is the correct statement of benefit, since the ordinary credit mechanism would have relieved the home charge rather than the foreign one.
- The differential is income-dependent rather than fixed. Kentucky's liability runs $1,457 at forty-five thousand dollars and $3,382 at one hundred thousand, against $3,999 in Michigan at the upper figure. Where one state applies a flat rate and the other a graduated schedule the gap widens or narrows monotonically with income, so a single-salary comparison understates how much the pairing matters across a career.
- The benefit is conditional on filing the exemption certificate with the employer, typically renewed annually. ⚠️ Employer withholding defaults to the work state in its absence, irrespective of eligibility, and the remedy is a nonresident return in Michigan. The practical failure mode is therefore not ineligibility but non-election — the agreement exists and the commuter simply never claims it.

What each state would charge, across the ladder
Reference wages for a single filer, not a claim about anyone's salary. The last column is the difference the agreement actually removes — which is the gap between the two states, not Michigan's whole charge.

What this page cannot tell you
- This covers wages from a job. It does not cover self-employment, rent or investment income — those follow the ordinary rules for Michigan.
- ⚠️ And it is a deal between two states. City and county taxes are not part of it, and several of these states have them.
- The comparison here assumes a single filer and treats both states as taxing the same income. Your own numbers will differ.
- Every agreement in this dataset applies to wages and salaries only. Business, rental, gain and investment income sourced to Michigan remains taxable there under ordinary nonresident rules, and a commuter with such income may still owe a Michigan return notwithstanding the agreement.
- ⚠️ Reciprocity binds the state layer only and commonly does NOT extend to municipal or county income taxes — Pennsylvania's local earned income tax is the standard example, remaining payable at the place of employment despite the state-level agreement. Local liabilities are excluded from every figure on this page.
- Figures are computed for a single filer at the stated wage, treating Kentucky's and Michigan's definitions of taxable income as equivalent and modeling the resident credit as limited to the home state's own liability. Real returns diverge on filing status, deductions each state allows separately, and credit limitation rules — so these are comparative magnitudes, not a computation of anyone's liability.
