Today voters are heading to the polls to decide on a local proposal but no local candidates will be on this primary ballot. Voters in the Port Huron Area School District are being asked to approve an 18-mill non-homestead tax renewal, which makes up nearly 13 percent of the district’s budget. Non-homestead taxes are assessed mainly on commercial and industrial properties. School districts can receive up to 18 mills from the tax. By collecting non-homestead taxes, school districts receive the full amount of funding. Districts are funded per pupil with a combination of state and local funds. The local funds come from the 18-mill tax levied on the municipalities the district serves. If the district does not receive the local portion, the per-pupil funding would be reduced by nearly 17 percent.
