What to do if you filed an extension and the clock is now running out for real.
When you filed a tax extension back in the spring, it likely felt like pressing a welcome pause button. An extension gives you breathing room to gather paperwork, resolve missing details, and avoid a rushed filing. But now, the calendar has turned to autumn, and the final IRS deadline—October 15—is officially around the corner.
At Evergreen Tax Solutions, we believe tax preparation should feel calm, structured, and completely supported—never like a last-minute scramble. If you’ve been putting off last year’s return, don’t panic. By taking a few practical steps today, you can cross the finish line smoothly, avoid penalty fees, and get total peace of mind.
Here is your step-by-step checklist to get ready for the October 15 deadline.
1. Schedule Dedicated Time to Organize Your Tax Documents
The hardest part of completing an extended return is simply starting. Treat your tax prep like an important business meeting by blocking out 1 to 2 uninterrupted hours on your calendar this week. Set up a clean physical workspace or a dedicated digital folder, turn off notifications, and gather all tax documents in one centralized place so you aren’t hunting for missing papers later.
2. Refer to Last Year’s Return (or Use a Tax Organizer)
Instead of guessing what forms you need, use your prior-year tax return or a tax organizer as your master checklist. Reviewing last year’s return reveals your recurring income sources, interest statements, mortgage forms (1098), and usual deduction categories, ensuring nothing slips through the cracks.
3. Finalize Your Bookkeeping for Last Year
If you operate a business or earn self-employment income, accurate taxes require clean records. Take time to reconcile your accounting software or financial spreadsheets for the prior tax year. Clear up any uncategorized transactions, verify account balances, and ensure all business revenue and expenses are fully accounted for before handing records over to your preparer.
4. Gather Business Income & Expenses (If Applicable)
For sole proprietors, LLC owners, and independent contractors, compile your total gross revenue along with categorized business expenses. Be sure to summarize key deduction areas, such as:
- Vehicle mileage or auto expense logs
- Equipment purchases and technology tools
- Professional fees, advertising, and insurance
- Home office usage details and utility records
5. Gather Rental Property Income & Expenses (If Applicable)
If you own rental property, summarize your total rental income received for each property during the tax year. Organize property-specific expense categories, including maintenance, repairs, management fees, property taxes, insurance, and mortgage interest, so your preparer can accurately calculate your depreciation and net rental income.
6. Confirm Estimated Tax Payments and Withholdings
To ensure you receive full credit for every dollar you’ve already paid toward last year’s tax bill, verify your payments before filing. Collect record dates and exact dollar amounts for all quarterly estimated tax payments made to the IRS and state agencies, and double-check your W-2 or 1099 tax withholding statements.
7. Do You Qualify to Contribute to a SEP IRA? (Deadline: October 15)
Here is one of the most powerful—and frequently overlooked—strategic advantages of filing an extension: retirement contribution flexibility. If you are self-employed or run a small business, you can establish and fund a SEP IRA for the prior tax year up until your extended filing deadline of October 15. Contributing to a SEP IRA allows you to shelter a significant portion of your net business income, directly lowering last year’s taxable burden even after the calendar year has ended.
8. The Golden Rule: Get Your Tax Info to Your Preparer by October 1st
To guarantee that your return is reviewed, calculated, and electronically filed without last-minute chaos or filing errors, your tax professional needs sufficient lead time. We strongly recommend submitting all your completed tax documents to your tax preparer no later than October 1st. This gives your strategist time to review every eligible deduction, confirm accuracy, and safely e-file before the October 15 deadline.
Turn Your Extension Into a Proactive Fresh Start
Filing an extension doesn’t mean you’re behind—it simply means you took extra time to get things right. Once last year’s return is filed, you can shift from looking in the rearview mirror to building a proactive, year-round tax plan that prevents future end-of-year surprises.
