Common confusion points

When do I file?

The trustee generally must file by April 15 of the year following the termination.

Check if the due date falls on a Saturday, Sunday, or legal holiday; if so, file on the next business day.

What happens if my TIN isn't ready?

If you do not receive the Taxpayer Identification Number (TIN) by the due date for Form 706-GS(T), write “Applied for” on line 1b.

Confirm that "Applied for" is written exactly as shown on Line 1b.

How do I pay electronically?

The IRS recommends electronic payment, and options include any of the listed payment methods (referencing IRS.gov/Payments).

Verify the specific accepted electronic payment options on IRS.gov/Payments.

What if my trust has multiple Schedules A?

If you have more than six Schedules A attached to Form 706-GS(T), enter the total GST tax from all Schedules A in excess of six on Line 6b.

Ensure this calculation is done correctly before entering the amount on Line 6b.

What if I'm using a PDS?

File at the specific address for PDSs: Internal Revenue Service, 333 W. Pershing Road, Kansas City, MO 64108.

Confirm that your chosen PDS is listed as designated by the IRS on IRS.gov/PDS.

What do I refer to if my trust was formed before a certain date?

If property is transferred into a pre-existing trust (Part II, Line 3), you must refigure the inclusion ratio and complete Part IV, line 11 stating how it was calculated.

Check if your situation requires completing Part IV, line 11 after answering 'Yes' to the pre-existing transfer question.
