Port Huron local tax guide
Who pays Port Huron's local tax
If you live in Port Huron, the 1% applies to all your wages, including a job at a Marysville plant or a remote job for a Detroit-area company. If you live outside the city and work in it, you owe 0.5% on pay for days worked within Port Huron. A resident who also pays another Michigan city's tax, such as Detroit's, can credit it up to Port Huron's 0.5% nonresident rate. Michigan's reciprocity agreements with other states cover state tax only, not city tax.
Port Huron's tax, explained
Port Huron, the St. Clair County seat at the foot of Lake Huron, has about 28,700 residents and has taxed income since 1969. It uses the default 1% / 0.5% rates from Michigan's uniform city income tax ordinance and runs its own income tax office.
Residents pay on all earned income; nonresidents pay only on income earned in the city. The city return lets you subtract a personal exemption for each person you claim. The figures on this page apply the rate to full wages, so your bill will be a bit lower than shown.
$75,000 in Port Huron, step by step
Start with $75,000 of wages. Federal income tax takes $7,670, Michigan takes $2,937, Social Security takes $4,650, and Medicare takes $1,088. A resident then pays $750 to Port Huron, leaving $57,905 a year, or $4,825 a month.
A nonresident who works at the hospital, the county building, or a downtown shop pays $375 and keeps $58,280. Living just outside the line and working outside it too means no city tax and take-home pay of $58,655.
On a $40,000 salary, a resident sends $400 to the city and keeps $32,471.
Nearest taxing cities
Port Huron is the only taxing city in St. Clair County. The nearest others on our list are Flint, Pontiac, and Detroit, each roughly an hour's drive or more away. Flint and Pontiac share Port Huron's 1% / 0.5% rates, and Detroit charges 2.4% to residents and 1.2% to commuters.
A Port Huron resident who commutes to Detroit pays Detroit's 1.2% and still owes Port Huron the part of its 1% that the 0.5% credit cap does not cover, $375 at $75,000.
Tips for Port Huron paychecks
Check your address before claiming residency
Port Huron Township borders the city, and many of its homes carry Port Huron mailing addresses. The township levies no income tax.
Ask suburban employers about city withholding
An employer in Marysville or St. Clair may not withhold Port Huron tax for residents. Make estimated payments if your stub shows none.
Keep records for split work weeks
If you work partly in Port Huron and partly elsewhere as a nonresident, a log of days in the city supports the allocation on your nonresident return.
