State tax nexus rules are a mess right now with remote work. The general rule is: you owe tax to every state where you work, even temporarily. But practical enforcement varies widely.

The IRS has been increasing enforcement in this area significantly. What you could get away with 5 years ago is being caught now. When in doubt, report conservatively and consult a CPA.

Keep meticulous records. The IRS loves to deny deductions for lack of substantiation. A $50 expense tracking app saves thousands in lost deductions during an audit.

Update: Thanks everyone for the guidance. I consulted with an attorney and we're moving forward. The advice here helped me understand what questions to ask and what to expect. Will update when there's a resolution.

I went through a nearly identical situation in 2024 and wanted to share what I learned. The 45-day identification window under IRC Section 1031(a)(3)(A) is an absolute deadline -- the IRS and the Tax Court have consistently refused to grant extensions, even for natural disasters or other hardship. In Christensen v. Commissioner, the court held that the identification period is jurisdictional and cannot be equitably tolled.

When you miss the 45-day window, the exchange fails and the entire gain from the relinquished property becomes taxable in the year of the sale. For most people, that means a combined federal and state capital gains tax hit of 20-30% or more, depending on your income bracket and state. If you had depreciation recapture under Section 1250, that portion is taxed at 25% federally regardless.

One thing worth exploring with your CPA: if the failed exchange happened near the end of the tax year, you may be able to use an installment sale election under IRC Section 453 to spread the gain over multiple years, provided the proceeds were held by a qualified intermediary and not constructively received all at once. This does not fix the failed 1031, but it can soften the tax blow significantly.

Also, the IRS has issued guidance (Rev. Proc. 2018-58) extending deadlines for taxpayers in federally declared disaster areas. If any part of your timeline overlapped with a FEMA-declared disaster in your area, it is worth checking whether you qualify for relief. I have seen this save taxpayers who missed deadlines during hurricane season.

Going forward, the best practice is to have at least three backup replacement properties identified before day 30, using the three-property rule. Never wait until the last week. I also recommend using a qualified intermediary who sends automated reminders at day 20, 30, and 40.

I missed my 1031 exchange deadline by 3 days last year and ended up owing $67,000 in capital gains taxes that I thought I had deferred. The 45-day identification period and 180-day closing deadline under IRC Section 1031 are absolutely strict. There are no extensions, no exceptions, and no relief provisions for missing them even by a single day.

What caused my failure was a title defect on the replacement property that required an additional week to clear. My qualified intermediary warned me that the deadlines were firm, but I assumed we could get an extension from the IRS. You cannot. The only recognized exceptions are for federally declared disaster areas, and even those are very narrow.

The one silver lining: I was able to offset some of the tax hit by using installment sale treatment under IRC Section 453 for the portion of the gain I had not yet received. If you carry back a note from the buyer, you can spread the gain recognition over the installment period. This does not eliminate the tax, but it can smooth out the impact over several years.

My advice for anyone planning a 1031 exchange: start identifying replacement properties on day one, not day 30. Have at least three backup properties identified in writing. And use a qualified intermediary who has handled at least 100 exchanges. The cheapest QI is not the best QI. My total savings from a successful exchange would have been $67,000 in taxes, and the cost difference between a good QI and a budget one is maybe $500.
