DEADLINE VISUALIZER
Enter the transfer date.
Visualize the standard federal 45-day and 180-day markers. Verify the actual deadline with your professionals.
IDENTIFICATION MARKER—45 days after transfer
180-DAY MARKER—subject to earlier return due-date rule
What this calculator does—and does not do.
The tool adds 45 and 180 calendar days to the date entered. The actual federal receipt deadline can be earlier because the IRS rule uses the earlier of 180 days or the applicable tax-return due date including extensions. Disaster relief and transaction-specific facts can also matter.
