You’re wrapping up another year in business, and between finishing up jobs and dealing with Montana’s winter weather, tax planning probably isn’t at the top of your list.
But here’s the thing: what you do in the next few weeks could save you thousands on your 2025 taxes. And most Montana contractors, HVAC technicians, electricians, and plumbers leave money on the table simply because they don’t know these moves exist.
We’ve been helping Montana service businesses with their taxes for over 15 years, and every December we see the same pattern. The business owners who take a few hours now save more money than those who wait until April and scramble.
Equipment Purchases (Section 179)
If you’ve been putting off that new work truck, compressor, or tools, now’s the time. Section 179 lets you deduct qualifying equipment purchases made before December 31, 2025.
What this means: Buy a work truck in late December? You can deduct it on your 2025 taxes. Buy the same truck on January 2nd? You wait a full year for that deduction.
What typically qualifies:
- Vehicles over 6,000 lbs (most work trucks and vans)
- Tools and equipment
- Office furniture and computers
- Commercial machinery
Action: If you’re planning a purchase for early 2026, ask yourself: could I make it before December 31 instead?
Talk to your tax professional about the specific limits and rules that apply to your situation. The deduction limits change each year, and the rules around vehicles can be complicated.
Pay Outstanding Business Expenses
Montana winters can be tough on cash flow, but if you have money sitting in your business account, consider prepaying some 2026 expenses before year-end.
You can typically prepay:
- Insurance premiums
- Rent (within limits)
- Supplies and materials you’ll use next year
- Software subscriptions and licenses
Why this matters:
These prepayments can reduce your 2025 taxable income. The exact savings depends on your tax bracket, but prepaying expenses is one of the simplest year-end moves you can make.
Retirement Contributions
Montana business owners can contribute to retirement accounts like SEP IRAs, Solo 401(k)s, or SIMPLE IRAs and deduct those contributions from 2025 income.
The Montana advantage:
Unlike Wyoming, Montana has state income tax. Retirement contributions reduce both your federal AND state tax bills.
What this looks like:
A Montana business owner making good money could contribute to a SEP IRA and save on both federal and state taxes. The exact savings depends on your income level and tax bracket.
Important: Contribution limits change each year and depend on your specific situation. We can help you figure out the right amount for your business.
Clear Out Old Inventory or Equipment
Got old inventory, obsolete equipment, or vehicles you’re not using? Donate or dispose of them before December 31.
Why: You can write off the remaining book value plus any disposal costs. For contractors, this might include:
- Vehicles you’re planning to replace
- Old tools that still work but you’ve upgraded
- Leftover materials from completed jobs
Collect Outstanding Invoices (Cash Basis Only)
If you’re on cash basis accounting (most small businesses are), you only pay taxes on money you actually receive.
December strategy:
If you had a strong year and want to defer some income, consider waiting until January 2 to deposit those late-December checks. This pushes that income into 2026.
Flip side: If you expect to make more money in 2026, push to collect everything before December 31 so you’re taxed at this year’s rate.
Which approach is right for you?
It depends on your specific situation. Let’s talk about it.
Review Your Entity Structure
Are you still operating as a sole proprietor? Montana LLCs and S-Corps can offer tax advantages, especially for service businesses with healthy profit margins.
Self-employment tax consideration:
Sole proprietors pay self-employment tax on all profit. S-Corp owners structure things differently – they take a reasonable salary plus distributions, and only the salary portion is subject to self-employment tax.
The potential savings can be significant for businesses with strong profitability. But S-Corps come with additional requirements and costs, so it’s not right for everyone.
Timing note:
You can’t change your 2025 entity structure now, but we can help you figure out if a change makes sense for 2026.
Get Your Books Cleaned Up
This isn’t technically a tax move, but it’s the foundation for everything else. You can’t make smart tax decisions with messy books.
What we see every December:
- Receipts in shoeboxes
- Personal and business expenses mixed together
- Months of transactions sitting in “uncategorized”
- Missing documentation for deductions
The reality: Business owners with messy books miss deductions simply because they can’t prove the expense or remember what it was for. We typically find thousands of dollars in overlooked deductions when we organize someone’s books.
Montana-Specific Considerations:
Seasonal Cash Flow:
Montana service businesses often see slower winters. Making smart tax moves now can help you preserve cash for January-March when work might be lighter.
State Tax Planning:
Montana’s state income tax means deductions save you money on both federal and state taxes – that’s more savings than you’d get in a no-income-tax state.
Spring Rush Preparation:
If you handle your 2025 taxes now, you’ll be ready when construction season hits in April/May instead of scrambling to file extensions.
