The end of the year brings more than holiday decorations and client gifts. For business owners, December is a time when tax decisions start to really matter. Business tax preparation feels different this time of year. Between year-end deadlines, staff time off, and last-minute expenses, it’s easy to feel like everything is speeding up right when most people want to slow down. That’s why early December is our chance to press pause and look at what can still be done before the books officially close.
Planning in this season isn’t just about rushing into write-offs. It’s about looking at where the numbers stand, what spending still makes sense, and how we can get to January without tax regret. It all adds up. What we do now affects how we file months from now. Here's how we help business owners stay clear-headed during one of the busiest times of the year.
Year-End Deadlines Come Fast
December tends to feel shorter than it is. Holiday closures, client vacations, and staff scheduling make the last few weeks of the year go quickly. That’s why it’s important to treat early December like the real deadline.
Missed cutoff dates are one common issue we see during this time. These might include:
• Getting payroll wrapped up before the final pay period
• Making sure retirement contributions are processed and posted
• Sending contractors the info they need so 1099s are ready in January
Another challenge is falling behind on regular bookkeeping when holiday distractions kick in. That leads to hurried decisions in the last week of December or scrambling to fix mistakes in January. When paperwork is turned in late or reports are delayed, it affects what shows up on the return and what you can deduct.
As part of a comprehensive approach, we can help Kansas City business owners streamline payroll processing and set reminders for important deadlines so nothing gets lost in the seasonal shuffle.
Planning Purchases Before December 31
Last-minute purchases can lower your taxable income if done with a little planning. But not everything qualifies, and not every deduction is worth the cash-out. The goal is to match real business needs with smart timing.
We talk through purchases like:
• Equipment or software upgrades you’ve already planned for
• Supplies that are used regularly and won’t sit on the shelf
• Business-related services or subscriptions billed before year-end
It’s important to keep records, too. Receipts, paid invoices, and delivery dates all help document the expense properly. If you’re unsure whether a purchase makes sense tax-wise, asking first can save money and hassle later on.
Holiday Payroll and Bonus Considerations
If your business hands out year-end bonuses, this is the moment to check the calendar. The timing of when bonuses are issued can affect both tax reporting and cash flow. Payroll software can handle a lot, but small details make a difference.
Here are a few things we often review:
• Will December paychecks post on time around holiday bank closures?
• Are bonuses being paid through payroll or separately?
• Are taxes being withheld accurately on those extra payouts?
Even regular payroll can cause stress when it lines up with holiday travel or snow days. Reviewing everything a week or two ahead allows room for changes and it avoids the feeling of being stuck when banks or systems are closed.
Sorting Through Seasonal Write-Offs
This time of year brings different spending patterns, and not everything “holiday-related” automatically counts as a business write-off. That’s why we take a close look at seasonal activities that might have tax effects.
Some examples include:
• Team lunches or client dinners that might count as partially deductible meals
• Travel to conferences or meetings (especially if they combine with vacation time)
• Gifts to employees or customers, which have strict dollar limits to qualify
The IRS doesn’t allow blanket write-offs for holiday cheer, and guessing usually leads to trouble later. Still, there are ways to document expenses correctly if you keep backup notes, receipts, and dates. Don’t forget to mention what the purchase was for; purpose matters as much as amount.
Because we offer both accounting and tax preparation services, our team can help clarify what qualifies as a deductible business expense during these complex holiday months.
Kansas City Weather, Slower Schedules, and Tax Prep Timing
For business owners around Lee’s Summit and across the Kansas City area, December weather plays a real part in planning. Snow or ice can slow down shipping, close offices, or delay deliveries. So can holiday traffic and shorter workweeks.
That makes it even more important to not push major decisions into the last few days of the month. If you need signatures, bank wires, or approvals, it helps to start earlier than usual.
Here’s what we usually prepare for:
• Delays caused by snow days and power outages
• Staff or vendors being out on vacation during the last week of December
• Fewer available hours to reach banks or submit documents
Staying ahead by a week or two gives time to work around these surprises, without stressing about how they affect taxes.

Stay Ready, Not Rushed: Ending the Year on a Clear Note
As the calendar winds down, the way we handle decisions now shapes how tax filing will feel next spring.
