Frequently Asked Questions

What documents do I need to provide for my business tax return?
You'll typically need your profit & loss statement, balance sheet, bank and credit card statements, 1099s you issued and received, W-2s for employees, records for vehicle use or home office expenses, asset purchase documentation, and a copy of your prior-year return. We provide a customized document checklist after our initial conversation to ensure nothing is missed and the process goes smoothly.
How much does business tax preparation in Brighton cost?
Our fees are transparent, competitive, and based on the complexity of your return and business structure, not a percentage of any refund or savings. After reviewing your documents in the initial assessment, we provide a clear, upfront quote with no hidden surprises. Most clients find that the value — through maximized deductions, avoided penalties, and year-round support — far outweighs the cost.
What are the filing deadlines for business tax returns?
Deadlines vary by entity type. For calendar-year businesses in 2026: S-Corporations and partnerships (Form 1120S or 1065) are generally due March 16; C-Corporations (Form 1120) are typically due April 15; and sole proprietors report on their individual return due April 15. Michigan state returns often align with federal dates. We track all deadlines for you and can file extensions when beneficial (note: extensions extend filing time but not payment).
Can you help if I receive an IRS or Michigan notice?
Yes. We provide full IRS and Michigan representation. If you receive a notice, letter, or audit inquiry related to your business return, bring it to us right away. Our team will review it, respond on your behalf (with proper authorization), and work to resolve the issue efficiently while minimizing any penalties or stress.
Do you help with estimated tax payments and quarterly filings?
Absolutely. We help calculate and schedule your federal and Michigan estimated tax payments to avoid underpayment penalties. This is especially important for S-Corps, partnerships, and sole proprietors. We can also assist with quarterly payroll tax returns (Form 941) and Michigan withholding or sales tax filings as part of our integrated services.
What if my business has employees or I need to issue 1099s?
We handle the related payroll tax compliance and can prepare or review 1099-NEC and 1099-MISC forms. Our payroll and bookkeeping services integrate seamlessly with tax preparation, ensuring everything stays consistent and audit-ready.
Can you help with tax planning throughout the year, not just at filing time?
Yes, that's one of the biggest advantages of working with us. We offer proactive year-round tax planning to help you make informed decisions on the timing of expenses, retirement contributions, equipment purchases, and business structure choices that can significantly reduce your future tax liability.
