Year-End Tax Things Sellers Forget to Ask About

As the year winds down, a specific kind of question starts showing up in my conversations with sellers: is there anything about timing my sale before December 31st that I should be thinking about? It's a smart question, and the honest answer is, it depends on your specific situation, so this is not tax advice, just a list of things worth bringing to your accountant or tax professional before you finalize your plans.

Capital gains exemptions have real thresholds. If the home you're selling has been your primary residence for at least two of the last five years, you may be able to exclude a significant portion of your gain from capital gains taxes, and the exact amount differs depending on your filing status. Whether your specific sale falls under, near, or over that threshold is worth confirming with a professional well before closing, not after.

Selling costs and certain improvements can affect your gain calculation. Real estate commissions, some closing costs, and documented capital improvements made over the years you owned the home can all factor into what your actual taxable gain looks like. Keeping records of major improvements, a new roof, a remodeled kitchen, is worth doing throughout ownership, not scrambled together at tax time.

Timing a sale across two tax years can matter for some sellers. Depending on your income situation for a given year, closing in December versus January can shift which tax year a gain lands in, which may or may not matter for your specific bracket or other income that year. This is highly individual, and worth a real conversation with your tax preparer rather than a rule of thumb from a blog post.

If you're carrying a second property, an investment property, or inherited real estate, the tax picture gets meaningfully more complex, and options like a 1031 exchange might be worth exploring well in advance of listing, not after you've already accepted an offer.

None of this replaces an actual conversation with a CPA or tax attorney who knows your full financial picture. But if you're thinking about a year end sale, bringing these specific questions to that conversation, rather than a vague "any tax stuff I should know about," tends to get you a much more useful answer.
