Work-location details that change the return

A CPA in Rockville should ask where the work was performed — not only where you live. Hybrid schedules and DC-area job hubs are positioned to influence withholding and credits as well as estimated payments.

Real-estate and compensation

Rockville’s higher home values make basis & improvements and rental activity worth tracking from day 1. Equity awards and bonus timing are also able to shift the scope of the return. We also support clients in nearby Bethesda and Gaithersburg who deal with the same DC-area commuting and filing questions.
