Single W2 from 2 "employers"
Client has a W2 from Trinet, an HR outsourcing company used by many startups.
He worked at 2 startups in 2025, and both use Trinet.
The W2 has a single amount in Box 1, under Trinet's EIN.
But for California withholding, there are 2 different State ID's, each with an amount. Apparently, each startup has its own State ID, even though they report payroll under Trinet's single Federal EIN.
I've done split withholding for different states, but how do I report CA withholding for 2 different CA state ID's?
Also, the Social Security tax was over $10,918 because there were 2 "employers." Lacerte says he should get this refunded by the employer, and not get a credit on Schedule 3, but Trinet was the only employer with a Federal EIN.
Any ideas?
