Are you thinking about selling an investment property in Bigfork and rolling the proceeds into something new without an immediate tax bill? You are not alone. Many Flathead County owners use Section 1031 exchanges to keep equity working while deferring federal capital gains tax. In this guide, you will learn the rules, timelines, and Bigfork-specific issues that matter, plus a practical checklist you can follow. Let’s dive in.
What a 1031 exchange is
A 1031 exchange lets you sell qualifying real property and reinvest into other like-kind real property while deferring recognition of capital gain. Both the property you sell and the one you buy must be held for investment or business use. Since 2017, exchanges apply to real property only, not personal property like equipment or furniture.
You cannot use a 1031 to defer tax on your primary residence. Mixed-use or vacation homes may still qualify when they are held primarily for investment and meet IRS factors that show business intent. Good records are essential.
Key timelines and rules
The 45-day identification window
You have 45 days from the closing date of your sale to identify potential replacement properties. Identification must be in writing and delivered to your qualified intermediary or the seller as instructed. The 45-day window is strict and cannot be extended.
The 180-day completion deadline
You must close on your replacement property or properties within 180 days of the sale. If your tax return is due earlier, that earlier date controls unless you file for an extension. Missing the 180-day deadline generally disqualifies the exchange.
How many properties you can identify
- Three-property rule: identify up to three properties, any total value.
- 200 percent rule: identify any number of properties as long as the combined value does not exceed 200 percent of the value of the property you sold.
- 95 percent exception: if you identify more than allowed, you must acquire at least 95 percent of the total value you identified.
Like-kind and investment intent
Real property is broadly like-kind to other real property if both are held for investment or business. Keep documentation that shows investment intent, such as leases, rental income statements, or advertising. This is especially important with vacation or mixed-use properties.
The role of the qualified intermediary
Use a qualified intermediary, often called a QI, to hold your sale proceeds and prepare exchange documents. You cannot receive or control the funds yourself. Engage the QI before closing so the escrow can route proceeds directly to the intermediary.
Taxes you defer and what counts as boot
Boot basics
Boot is any cash or non–like-kind property you receive. It is taxable to the extent of your realized gain. A reduction in mortgage debt can also create boot. If the replacement property has less debt and you do not add cash or new financing to make up the difference, that shortfall can be taxable.
Depreciation recapture
Depreciation you have taken does not disappear in a 1031 exchange. It is deferred. When gain is recognized later, depreciation recapture rules apply. For real property, a portion may be taxed as unrecaptured Section 1250 gain at rates up to 25 percent.
Related-party and holding periods
Transactions with related parties have special rules. Transfers within a common two-year window can jeopardize deferral unless IRS anti-abuse conditions are met. Plan carefully and get professional guidance if family members or related entities are involved.
Exchange types beyond the standard
Reverse exchanges
In a tight market, you may need to buy first. A reverse exchange allows you to acquire the replacement property before selling the relinquished one. An Exchange Accommodation Titleholder holds title temporarily during the swap. Reverse exchanges are more complex and often more expensive, so start early.
Improvement exchanges
If you need to build or renovate to meet your investment goals, an improvement exchange can help. Funds and title are parked with an accommodator while improvements are made. All improvements counted in the exchange must be completed within the 180-day period.
Bigfork and Flathead realities
Common property types in exchanges
In Bigfork and across Flathead County, you often see lakefront homes, cabins and cottages, residential rentals, short-term rental units near Flathead Lake and gateway towns, vacant land and recreational parcels, and small commercial assets like retail or lodging. Each has different leasing, permitting, and seasonality factors.
Short-term rental checks
Local rules can affect short-term rentals, including zoning, licensing, inspections, and occupancy taxes. Before you identify a replacement property, review county and municipal requirements and any HOA covenants to confirm that the permitted uses match your investment plan.
Zoning, septic, water, and shoreline
Septic permits, well and water rights, and shoreline protections near Flathead Lake can affect value and rental potential. Confirm existing permits and any limitations on expansion or remodeling. If a property relies on a septic system or is near protected shoreland, build extra time for due diligence.
Title, easements, and resource rights
Rural and recreational parcels may include timber or mineral reservations, conservation easements, or lake access easements. These can shape use and value. Order title work early and review exceptions closely so you are not surprised during the 45-day window.
Financing and timing in a small market
Bigfork is a smaller, resort-driven market. Inventory that fits a 45-day identification plan can be limited. If you will use financing, coordinate with your lender early and make sure underwriting timelines align with the 180-day deadline. Also remember that replacing equal or greater debt helps you avoid taxable boot.
Vacation homes and STRs in Bigfork
Many Bigfork owners balance personal use with rental income. To qualify for a 1031, the primary purpose must be investment or business use. Follow the IRS factors for dwelling units and keep clear records: rental agreements, booking calendars, income and expense statements, and any property management contracts. Strong documentation helps show investment intent.

FAQs
Can I use a 1031 for a Bigfork vacation house?
- Possibly, if it is held primarily for investment and you can document rental activity that shows business use under IRS factors.
What happens if I miss the 45 or 180 days?
- Missing either deadline generally disqualifies the exchange and triggers immediate recognition of taxable gain.
Can I buy a replacement property outside Montana?
- Yes, exchanges can cross state lines, but state tax rules vary so consult a Montana CPA about reporting and conformity.
How do I avoid boot in a 1031 exchange?
- Reinvest all net proceeds and replace equal or greater debt on the replacement property, or add cash to cover any debt shortfall.
Does a 1031 exchange eliminate my taxes forever?
- No, it defers tax; when you later sell without another 1031, deferred gain and depreciation recapture can become taxable.
What local issues should I check in Flathead County?
