Practice Lab 2017 was activated yesterday, 15 Nov 2017, for federal returns only. In parallel with that, the IRS’s Link & Learn site was also activated. That means you can now start to take your certification tests online.
One note of caution: the printed version of Form 6744, VITA/TCE Volunteer Assistor’s Test/Retest that you received as part of your training package is missing page 92. You must download that page from the electronic version Form 6744, VITA/TCE Volunteer Assistor’s Test/Retest. It looks like this:
TaxSlayer has also reported a Practice Lab 2017 problem with short- and long-term carryover losses not carrying forward to Form 1040. See this post from the TaxSlayer blog: Practice Lab 2017: Short Term and Long Term Loss Carryover.
That means that you cannot complete the advanced certification test until this is fixed. When resolved, TaxSlayer will post that information on their blog. We highly recommend you either follow or frequently check the TaxSlayer Blog for status updates on Practice Lab 2017.
