If you received a tax filing extension, October 15 is an important date to remember. For Michigan residents, meeting the federal extension deadline also means making sure your Michigan state income tax return is completed and filed correctly. Whether you live in Grand Rapids, Kentwood, Wyoming, or elsewhere in West Michigan, AIM Financial can help you navigate the tax filing process and avoid common mistakes.

With the October 15 deadline approaching, now is the time to organize your tax documents, review your income, and prepare your Michigan income tax return.

1. Understand What a Tax Extension Does

One of the most important tax extension facts is that an extension gives you additional time to file your tax return, not additional time to pay your taxes.

For most individual taxpayers who received a valid federal extension, the filing deadline is October 15. Michigan generally recognizes a valid federal extension for state income tax filing purposes, subject to applicable state requirements.

However, if you owe Michigan income tax, payment was generally due by the original April deadline. Unpaid balances may be subject to interest and penalties. Filing your return promptly can help you understand what you owe and address outstanding tax obligations.

2. Gather Your Michigan Tax Documents

Before filing your Michigan income tax return, collect all the documents needed to report your income, deductions, and credits accurately.

Common documents include:

• Form W-2: Reports wages and Michigan income tax withholding.
• Forms 1099-NEC and 1099-MISC: Report certain self-employment and other income.
• Interest and dividend statements: Help ensure investment income is reported correctly.
• Federal Form 1040: Provides important information used to prepare your Michigan return.
• Estimated tax payment records: Help verify payments already made.
• Michigan-specific tax records: Include information needed to claim eligible state credits or deductions.

Having complete documentation available can reduce filing delays and help prevent errors that may lead to notices from the Michigan Department of Treasury.

3. Review Michigan Tax Credits and Deductions

Michigan taxpayers may qualify for credits that reduce their state income tax liability or increase their refund. Depending on your circumstances, these may include the Michigan Homestead Property Tax Credit or the Michigan Earned Income Tax Credit for qualifying workers.

Eligibility depends on factors such as household income, residency, property taxes or rent, and other requirements. Review your eligibility carefully rather than assuming you do not qualify.

A professional tax preparer can help identify applicable credits and ensure the correct information is included with your Michigan return.

4. Check Your Federal and Michigan Returns for Consistency

Your Michigan income tax return generally relies on information reported on your federal return. Differences in income, withholding, or other tax information can create errors and potential processing delays.

Before filing, verify that your names, Social Security numbers, income figures, and tax payments are correct. If you are self-employed, operate a small business, receive retirement income, or have multiple income sources, additional review may be especially important.

If you discover an error on a previously filed return, determine whether an amended return is necessary instead of simply repeating the incorrect information.

5. File Before October 15 With Help From AIM Financial

Waiting until the last minute can make it harder to resolve missing documents, correct mistakes, or determine whether you qualify for Michigan tax credits. Electronic filing may help speed up submission and processing, but it does not guarantee an immediate refund.

If you have not completed your Michigan income tax return, start gathering your documents now. Make sure you understand any outstanding balance and confirm the filing requirements that apply to your situation.
