It often starts in January as a quiet reminder. By February—when W-2s and 1099s are due—it becomes more urgent. By March or April, many business owners feel behind.
Tax season does not have to create stress.
With a structured pre-filing checklist and a disciplined year-end close process, you can reduce errors, avoid penalties, and position your business for smarter financial decisions.
At IKRG CPAs and Consultants PC, we help small businesses and individuals prepare for tax filing by focusing on accurate bookkeeping, proper documentation, and compliance with both IRS and Michigan Department of Treasury requirements.
Below is a practical, publish-ready checklist to help you close your books before Tax Day.
Why a Clean Year-End Close Matters
A timely and accurate year-end close is about more than filing a tax return.
It helps you:
- Identify true profitability
- Maximize legitimate tax deductions
- Avoid IRS and Michigan penalties
- Improve lender and investor confidence
- Reduce accounting and tax preparation costs
Poor financial visibility leads to poor decision-making. When your books are reconciled and verified before filing, your tax return becomes a reflection of clean financial operations—not a scramble to reconstruct them.
Core Principles of Pre-Tax Preparation
Before diving into the checklist, focus on three foundational accounting principles:
1. Verification
Every balance should be confirmed against a third-party source such as a bank statement, loan statement, or payroll report.
2. Separation
Personal and business expenses must be clearly separated. Commingling funds is one of the most common audit triggers for small businesses.
3. Documentation
If it is not documented, it is not defensible. Receipts, invoices, mileage logs, payroll reports, and asset purchase records should be organized and accessible.
The 10-Step Pre-Filing Checklist
1. Reconcile All Bank and Credit Card Accounts
Reconcile every account through December 31.
Action:
Match your accounting software (QuickBooks, Xero, etc.) to official bank and credit card statements.
Why it matters:
Reconciliation catches data entry errors, duplicate transactions, missing deposits, and potential fraud.
2. Separate Personal and Business Expenses
Review expense accounts for personal charges.
Action:
Reclassify personal transactions as Owner’s Draws or Distributions—not deductible business expenses.
Why it matters:
The IRS and Michigan Department of Treasury closely examine commingled expenses during audits.
3. Reconcile Payroll and 1099 Reporting
Labor expenses must match what was reported to the government.
Action:
- Compare payroll expense totals to your filed W-3.
- Confirm that all required 1099-NEC forms were issued for contractors paid $600 or more (non-card payments).
Deadline Reminder:
1099-NEC forms are generally due January 31.
Why it matters:
Late or missing 1099 filings can result in avoidable penalties.
4. Michigan Personal Property Tax (Form 5076)
Michigan business owners often overlook this requirement.
Action:
If your business owns equipment, furniture, or computers, review whether you qualify for the Small Business Property Tax Exemption.
If the true cash value is under the state threshold, you may file Form 5076 with your local assessor.
Deadline:
Typically due February 20 (postmark usually accepted).
Why it matters:
Failure to file can result in losing your exemption and receiving an unexpected local tax bill.
5. Review Accounts Receivable
If you use accrual accounting, you may be taxed on income not yet collected.
Action:
Run an Open Invoices report. Identify uncollectible accounts and evaluate whether they qualify as bad debt write-offs.
Why it matters:
Writing off legitimate bad debt reduces taxable income appropriately.
6. Perform a Year-End Inventory Count
If you sell products, inventory directly impacts Cost of Goods Sold (COGS).
Action:
Conduct a physical inventory count as of December 31.
Why it matters:
Incorrect inventory values distort profit margins and can create audit risks if gross margins appear unreasonable.
7. Review and Capitalize Fixed Assets
Large purchases should not always be expensed immediately.
Action:
Identify equipment, vehicles, machinery, or improvements over your capitalization threshold (commonly $2,500 or more).
Discuss eligibility for Section 179 depreciation or bonus depreciation with your CPA.
Why it matters:
Proper asset classification ensures accurate reporting and maximizes allowable deductions.
8. Document Auto and Home Office Deductions
These deductions are valuable but heavily scrutinized.
Auto Deduction:
Maintain a mileage log documenting business versus personal use.
Home Office Deduction:
Measure the square footage of your dedicated office space relative to total home size.
Why it matters:
Estimated numbers without documentation do not withstand audit review.
9. Reconcile Michigan Sales Tax
Michigan businesses must reconcile collected sales tax against amounts remitted.
Action:
Compare your POS or accounting system totals to payments made to the State of Michigan.
Annual Return Reminder:
The Sales, Use, and Withholding (SUW) Annual Return is generally due February 28.
Why it matters:
Unpaid sales tax can result in penalties, interest, and collection actions.
10. Conduct a Profit & Loss Variance Review
Before finalizing your books, review year-over-year performance.
Action:
Run a Profit & Loss comparison (current year vs. prior year).
Look for:
- Significant increases or decreases in revenue
- Unusual expense spikes
- Margin shifts
Why it matters:
Large unexplained variances often indicate classification errors or missing entries.
Filing Deadlines to Remember
- March 15: S-Corporations and Partnerships
- April 15: Most Individuals and C-Corporations
- January 31: 1099-NEC filing deadline
- February 20: Michigan Form 5076 (Small Business Property Tax Exemption)
- February 28: Michigan SUW Annual Return
Extensions may provide more time to file, but not more time to pay taxes owed.
Benefits of Closing Your Books Early
When your financial close is completed before tax filing:
- Returns are filed on time
- Extensions are less likely
- CPA fees are lower (less cleanup required)
- Deduction opportunities are identified proactively
- Audit exposure is reduced
A clean financial close transforms tax season from a last-minute obligation into a controlled process.
