Bethesda-specific tax prep

What Bethesda tax prep
actually requires.

Bethesda's tax-prep workload reflects its concentrated economy: medical and dental practices around NIH, biotech and life sciences along Rockville Pike, professional services along Bethesda Row. The Maryland tax stack — Form 502, Form 510, MW508, SDAT business personal property, and the elective MD PTET — overlays specific federal complexity (Form 6765, Section 174, Section 199A QBI). Below is what we handle as part of standard year-end tax prep coordination.

Maryland state returns (502, 510, 510-PTET)
Maryland residents file Form 502. Maryland pass-throughs file Form 510 with K-1s for partners. The Maryland Pass-Through Entity Tax election uses Form 510-PTET, paid at the entity level to preserve the federal SALT deduction. Worth modeling each year before the deadline; your CPA decides — we make sure the books support the choice.
SDAT business personal property + Montgomery County PPT
Maryland's State Department of Assessments and Taxation requires every business to file an annual Personal Property return by April 15. Filing claims the small business exemption (which often zeroes out the tax). After SDAT processes, Montgomery County issues a separate County personal property tax bill. We handle both as part of standard Bethesda engagements and reconcile against fixed-asset depreciation in QuickBooks.
R&D Tax Credit (Form 6765) for biotech
Federal R&D credit applies to qualified research expenses — direct R&D labor, supplies, and 65% of contract research. Maryland also offers a separate state R&D credit. For Bethesda biotechs, both are typically material. We organize project-level documentation through the year so your CPA can compile Form 6765 and Maryland's R&D credit application efficiently.
Section 174 R&D capitalization
Since 2022, federal tax law requires capitalizing and amortizing R&D expenditures over 5 years (15 for foreign R&D). For pre-revenue Bethesda biotechs and software companies this can produce taxable income on paper despite operating losses. We track Section 174 qualified expenses through QuickBooks classes so your CPA has clean source data.
Section 199A QBI for medical and dental practices
Medical and dental practices are "specified service trades or businesses" (SSTBs) under Section 199A — the qualified business income deduction phases out above income thresholds. We organize the books to support reasonable comp analysis, owner-employee W-2 documentation, and Section 199A modeling for your CPA.
NIH grant accounting + cost-share reporting
Bethesda biotechs and research companies frequently hold NIH grants. Year-end tax prep requires reconciling grant draw-downs against allowable costs, segregating direct R&D labor from indirect, applying your negotiated F&A (indirect cost) rate cleanly, and supporting any cost-share commitments. We coordinate with your federal grants office.

A representative tax-prep engagement

What a typical Bethesda
tax-prep engagement looks like.

A small Bethesda biotech (S-corp, four founders, twelve employees, two NIH grants in active draw-down) came to us late in the fiscal year. Their CPA had flagged three concerns: Section 174 R&D capitalization wasn't being tracked, Form 6765 substantiation was missing for prior years, and the founders hadn't elected Maryland PTET. They were also missing the Maryland state R&D credit application.

Over five weeks we set up Section 174 qualified-expense tracking by project through QuickBooks classes, built a Form 6765 substantiation file from contemporaneous documentation (project descriptions, qualified labor hours by employee, contract research with subs), filed the Maryland state R&D credit application, modeled the PTET election impact for the four founders, and reconciled twelve months of NIH grant draw-downs against allowable costs and indirect cost recovery. Their CPA filed an amended prior-year return claiming federal and Maryland R&D credits, current-year Section 174 amortization is now correctly tracked, and they elected Maryland PTET starting that fiscal year.

That's a representative composite — not a single real client — but it's a pattern we see two or three times a quarter in Bethesda's biotech and life sciences community.

Frequently asked questions

Bethesda, MD tax prep
FAQ.

How much does small business tax prep cost in Bethesda, MD?+
For a Bethesda small business or practice, year-round tax-prep coordination typically runs $350–$1,500 per month. Plans start at $350/month for sole practitioners, $650/month for established practices needing weekly close, and $1,500/month for the CFO Partner tier. CPA tax-return preparation fees are separate ($1,500–$5,000+ for a typical practice or biotech return depending on complexity).
Should my Bethesda practice or biotech elect Maryland PTET?+
Maryland PTET (Pass-Through Entity Tax) is elective and can preserve the federal SALT deduction by paying Maryland tax at the entity level rather than passing it through. Your CPA models the math; we make sure the books support the choice and that estimated PTET payments hit the right account. Election uses Form 510-PTET.
How does the Section 199A QBI deduction work for my Bethesda dental or medical practice?+
Medical and dental practices are "specified service trades or businesses" (SSTBs) under Section 199A. The 20% qualified business income deduction phases out above income thresholds. We organize the books to support reasonable comp analysis, owner-employee W-2 documentation, and the Section 199A modeling your CPA does at year-end.
How does the federal R&D Tax Credit (Form 6765) work for a Bethesda biotech?+
Federal R&D credit applies to qualified research expenses — direct R&D labor, supplies, and 65% of contract research. We organize project-level documentation throughout the year (qualified labor hours, project descriptions, contract research) so your CPA can compile Form 6765 efficiently. Maryland also has a separate state R&D credit; we handle that application too.
What is SDAT business personal property and do I have to file it?+
SDAT is Maryland's State Department of Assessments and Taxation. Every Maryland business — practices, biotechs, professional services — must file an annual Business Personal Property return by April 15. Filing claims any small business exemption that often zeroes out the tax owed. Failing to file forfeits the exemption and triggers an estimated assessment.
How does Section 174 R&D capitalization affect my Bethesda biotech?+
Since 2022, federal tax law requires capitalizing and amortizing R&D expenditures over 5 years (15 for foreign R&D). For pre-revenue biotechs this can produce taxable income on paper despite operating losses. Tracking qualified Section 174 expenses through QuickBooks classes provides clean source data for the amortization schedule.
Can you handle NIH grant accounting and tax-prep coordination?+
Yes. We set up project-by-project tracking in QuickBooks aligned to NIH (and NSF, BARDA, DoD) award structures, reconcile draw-downs against allowable costs, apply your negotiated F&A rate, and reconcile QuickBooks project P&Ls against federal cost-share reports each quarter. We coordinate with your CPA on year-end tax positions.
