The Q4 Financial To-Do List, Before the Ball Drops

December 31st doesn't wait for you to feel ready. Start here in October.

We know how it goes. The holidays hit, the calendar fills up, and suddenly it's January and you're digging through receipts while a tax deadline looms. Year-end doesn't have to feel like a scramble.

Below is your Q4 to-do list, sequenced by the deadline that actually matters, so you always know what's next.

October: Clean Up the Books

You can't plan with numbers you don't trust. Use this month to get current.

• Reconcile every account through September. Bank, credit card, loans, and payment processors.
• Clear out the "uncategorized" bucket. Every mystery transaction is a question your accountant will ask in March.
• Chase old receivables. Follow up on overdue invoices now, while there's still time to collect before year-end.
• Collect W-9s. Get one from every contractor you've paid this year. Note that for 2026 payments, the 1099-NEC threshold rises from $600 to $2,000.

November: Plan While You Still Have Options

Once your books are clean, you can see where the year is landing. That's when real decisions become possible.

• Run a year-end projection. Estimate full-year profit so your tax bill isn't a surprise.
• Sit down with your tax advisor. Talk through timing on income, expenses, and equipment purchases before the window closes.
• Review owner pay. S-corp owners should confirm their salary is reasonable and processed through payroll.
• Build your 2027 budget. Use this year's actual numbers, not last year's guesses.

December 31: The Hard Stop

These moves only count for 2026 if they happen before the ball drops.

• Max out retirement contributions. The 2026 401(k) employee limit is $24,500, plus an $8,000 catch-up if you're 50 or older.
• Make deductible purchases. Equipment or software you need anyway must be bought and placed in service by December 31.
• Run your final payroll. Include any year-end bonuses you plan to deduct this year.
• Count inventory. Retailers and restaurants, a year-end count keeps your cost of goods accurate.

January: Close the Loop

The calendar flips, but 2026 isn't quite finished with you.

• January 15, 2027: Q4 estimated taxes are due. This payment covers September through December income. Your November projection tells you what to send.
• February 1, 2027: W-2s and 1099-NECs are due. The usual January 31 deadline falls on a Sunday, so it moves to Monday. Those W-9s you collected in October make this easy.
• Close December's books. A clean final month means a smooth, on-time tax return.
