Basis Calculation Support

Basis calculation support determines the carried over tax basis in replacement property for Denver, Colorado investors completing a Section 1031 exchange, a figure that directly affects both future depreciation deductions and the gain that will eventually be recognized if the replacement property is sold outside of another exchange. Unlike a standard purchase where basis simply equals the purchase price, exchange basis calculation starts with the adjusted basis of the relinquished property, then adjusts for any additional cash invested, debt assumed, boot received, and selling or exchange expenses, producing a figure that is often meaningfully lower than the replacement property's fair market value or purchase price.

We compile the inputs needed for this calculation, including the relinquished property's original purchase price, accumulated depreciation taken over the ownership period, any capital improvements made during ownership, and the closing statement figures from both the relinquished property sale and replacement property purchase, since each of these figures feeds into the basis formula the investor's CPA will ultimately use to complete IRS Form 8824.

Why exchange basis differs from purchase price

Exchange basis is generally calculated as the adjusted basis of the relinquished property, plus any additional cash the investor contributes to acquire the replacement property, plus any gain recognized on boot received, minus any cash boot received and minus any liabilities assumed by the other party, adjusted further for exchange expenses. This produces what is often called a substituted or carryover basis, which is typically lower than what the investor would have if they simply purchased the replacement property for cash without an exchange, because the deferred gain from the relinquished property effectively transfers into the replacement property's basis rather than being taxed and reset.

This lower basis has real consequences for future depreciation, since annual depreciation deductions on the replacement property will be smaller than they would be on a property acquired with a full, non-substituted basis at the same purchase price. We walk investors through this tradeoff clearly, since deferring gain today through an exchange means carrying forward a lower depreciation basis, which is a deliberate exchange of a larger current tax benefit for continued deferral of the underlying gain.

Supporting depreciation schedule planning

Once the substituted basis is calculated, we help organize the information needed for the investor's CPA to establish a new depreciation schedule for the replacement property, which under current IRS guidance generally requires allocating the carryover basis to the replacement property's remaining depreciable life while separately depreciating any additional basis created by new cash invested. This allocation affects the investor's annual tax deductions going forward and should be handled carefully to avoid either overstating or understating depreciation in future tax filings.

A Section 1031 exchange defers, rather than eliminates, capital gains and depreciation recapture tax, and the carryover basis calculated here is what determines the eventual gain if the replacement property is later sold outside of another exchange. This service compiles inputs and supports the calculation process; it does not constitute tax advice or a substitute for the investor's CPA completing the actual basis and depreciation calculations required for tax filing. Denver, Colorado investors should have final basis figures confirmed by their CPA.

For Denver, Colorado investors, the carryover basis calculated through an exchange affects both federal depreciation deductions and, indirectly, the eventual Colorado state tax liability if the replacement property is later sold outside of another exchange, since Colorado generally follows federal basis treatment for state income tax purposes. We compile basis inputs with this downstream state tax consequence in mind, ensuring the investor's CPA has what is needed not just for the current year's Form 8824 but for accurate depreciation and future gain calculations for as long as the replacement property is held.

We also compile records of any capital improvements made to the relinquished property during the investor's ownership period, since these improvements increased the property's basis before the exchange and need to be accounted for correctly in the substituted basis calculation carried into the replacement property, a detail that is easy to miss without a complete improvement history.

Where an investor has owned the relinquished property for many years, original purchase records and improvement invoices are not always readily available, and we help identify alternative sources, such as prior tax returns showing depreciation schedules or county assessor records, that can help reconstruct a defensible basis history when original documentation has been lost over time.
