How to file your US Tax Return
In most cases, we are able to electronically file your US tax return. However, the IRS e-Filing system doesn't yet accept all return types. Please see our filing and signing instructions below for tips on getting your return submitted successfully.

Form 8879 - Where to sign and file

Form 8879 is an IRS authorisation form, allowing your tax accountant to electronically file your tax return.
​
This should not be posted to the IRS.
​
You should sign, and send the signed copy to your US Tax Team accountant.
Form 1040 - Where to sign and file

Form 1040 should only be posted to the IRS if it cannot be electronically filed. Your tax accountant will advise you on this.
​
If you are filing your tax return under the Streamlined Filing Amnesty program, you should skip straight to Form 14653 below.
