The principal residence exclusion is a fixed amount, not a percentage, so on a long-held property in an appreciating market it covers a diminishing share of the gain. The practical work is documenting your basis — capital improvements over decades — and doing it before you list rather than during escrow.
Most sellers never think about it, because an exclusion covers the gain for the majority of transactions. At the top of the market that stops being true.
Most sellers of a primary residence never think about capital gains tax, because a longstanding exclusion covers the gain for the great majority of transactions. At the top of the market that stops being true, and the shortfall can be substantial.
This is general information rather than tax advice. The rules have conditions and exceptions, and anyone with a meaningful gain should take specific advice well before a sale.
Gain on the sale of a principal residence is excluded up to a set amount, with a larger figure available to married couples filing jointly than to individuals.
Two conditions generally apply. You must have owned the property for a minimum period, and you must have used it as your principal residence for a minimum period, both measured within the several years preceding the sale. The exclusion can generally only be claimed once within a defined window.
Those thresholds are specific and worth confirming with an advisor against your own timeline, because a sale a few months early can cost the entire benefit.
The exclusion is a fixed amount rather than a percentage.
On a property held for decades in an appreciating market, the gain frequently exceeds it by a wide margin. The exclusion still helps, but it covers a diminishing share of the total, and the balance is taxable.
Sellers who have not looked at this since their last transaction are often working from an assumption that no longer applies to their position.
Gain is the sale price less selling costs less your basis. Most people understate their basis, and every dollar of understatement is taxed.
Basis starts at what you paid and increases with capital improvements — work that adds value or prolongs the property's life, as distinct from repairs and maintenance.
On a property held a long time, that can be a great deal: additions, a new roof, replaced systems, a pool, landscaping construction, a seawall, permanent fixtures.
The problem is documentation. Receipts from twenty years ago are frequently gone, and undocumented improvements are difficult to defend.
If you have owned a property for a long time and expect to sell eventually, assembling that record now is worth doing while it is still possible. Permits, invoices, contractor records, plans, photographs.
Commission, legal fees, title costs, transfer taxes and certain other transaction expenses generally reduce the amount realized.
Some pre-sale preparation may also be treated favorably where it constitutes improvement rather than routine upkeep. Where the sums are meaningful, ask an advisor how to characterize the work rather than assuming.
Property that was rented at some point. Depreciation taken while it was a rental is generally recaptured on sale and is not covered by the exclusion. Periods of non-qualified use can also reduce the exclusion proportionally.
A home office claimed over years. Similar treatment for the portion involved.
Ownership through an entity. The exclusion generally requires individual ownership, and property held in certain structures may not qualify at all.
Death of a spouse. Timing can matter considerably to both the exclusion available and the basis position.
Divorce. Ownership and use periods can be affected by the terms of a settlement.
Each of these is a reason to have the conversation before listing rather than during escrow.
Assemble the improvement record now, particularly on a long-held property. Speak to a tax advisor before you list, not after you have an offer. And confirm the current thresholds and conditions rather than relying on what you remember from a previous sale.
The planning that helps is nearly all done before a property goes on the market. Once it is under contract, the options narrow considerably.
