.T18 File

The t18 file extension is probably associated with the H&R Block, a family of tax preparation software, developed by HRB Digital for Windows and Mac. It is used for one of the default file types.

The t18 file represents tax return for the 2018 accounting year.

In the past H&R Block used t17, t16, t15, t14,... file extensions for the same purposes.

A t18 file extension represents tax returns forms for the tax year 2018 prepared using the H&R Block software by HRB Digital.
