1031 Deadline Calendar Calculator

1031 deadlines are strict — no extensions.

Days to identification deadline

59

Days to 180-day closing deadline

194

Recommended cushion (45-day from close)

30

How the math works

Identification day = sale close + 45. Closing day = sale close + 180. Aim for identification by day 30 for cushion.

Sale in 14 days: identify by day 59, close by day 194. Calendar reminders essential — no extensions allowed.

How this calculator works

What this page estimates

This 1031 Deadline Calendar Calculator is built to give a quick, browser-based estimate for 1031 deadline calendar. 1031 deadlines are strict — no extensions. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

  • Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
  • Run a low, base, and high case when the inputs are estimates.
  • Check the related calculators below when the next decision depends on a different assumption.

How to interpret the 1031 deadline calendar result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this 1031 deadline calendar estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

How to Use

  1. Enter sale close date (days from today).
  2. Read identification deadline and closing deadline.

Frequently Asked Questions

What are the deadlines?

45 days to identify replacement property (must be in writing to QI). 180 days to close on identified property. Both start the day after closing on relinquished property. No weekends or holidays extensions. Failed deadline = disqualified exchange = full tax due.

Identification rules?

Three-property rule: identify up to 3 properties regardless of value. 200% rule: identify more than 3 if aggregate FMV < 200% of relinquished value. 95% rule: must acquire 95% of identified value if more than 3 identified. Use 3-property rule in virtually all cases.

Cushion?

Sophisticated investors identify and go under contract by day 30 or earlier. Allows 15+ days of due diligence slack. Closing by day 150 leaves 30-day cushion. Tight timelines plus closing issues create disqualification risk — plan conservatively.
