Rockville, MD Bookkeeping Services — Lab-Grade Accuracy for the Biotech Corridor
Rockville sits at the heart of the #3-ranked biopharma cluster in America — 350+ life-science companies within minutes of NIH, FDA, and NIST — alongside the county seat’s law firms, healthcare practices, and Rockville Pike’s commercial mile. Biotech money is milestone money: grants, tranches, and R&D burn that demand disciplined books. Maxim Liberty has kept them since 2005 — from $75/month.

Running the Numbers in Rockville
Rockville is a CITY inside Montgomery County — and that matters for equipment-heavy labs: the city adds its own $0.8050 personal property levy on top of the county’s $1.6855, putting Rockville’s combined rate near $2.49 per $100 of depreciated value. For a startup with $500K in lab equipment, correct depreciation classes are worth real money every year. Meanwhile grant accounting (federal SBIR/STTR, state programs) needs cost tracking that survives an audit, and clinical-stage companies need burn visibility their board actually trusts.

Rockville Bookkeeping FAQs
Why is our equipment taxed more than a Bethesda competitor’s?
Rockville layers a municipal personal property tax ($0.8050) on top of Montgomery County’s $1.6855; unincorporated Bethesda pays county-only. Same county, ~48% higher equipment rate — which makes accurate depreciation and asset-location records genuinely valuable.
Is our SBIR grant taxable revenue?
Grant treatment varies — but in the BOOKS, grant proceeds must be tracked against eligible costs, separately from product revenue and investment. We build that structure so your CPA makes the tax calls from clean numbers and your program officer gets reports without a scramble.
What’s the one Maryland deadline we must not miss?
April 15 — the $300 SDAT Annual Report plus personal property return. Late filings stack penalties and put your entity’s good standing at risk, which surfaces at the worst times: financings, licensing, exits.
