Tax and accounting practice
Tax and accounting help for businesses, owners, and nonprofits.
Marginwall is based in Oswego, New York and helps with business returns, owner tax situations, nonprofit filings, notices, prior-year issues, and records that need to make sense before the return is filed.
New matters start with a short intake so the firm can review the facts, deadlines, records, and fit before quoting or accepting work.
Representative work
- S corporation returns
- Partnership returns
- Form 990 preparation
- Owner returns
- IRS or state notices
- Prior-year filings
The practice
The work usually starts with what is behind the return.
Marginwall leads with business tax and nonprofit compliance. Owner returns, notices, cleanup, bookkeeping, and payroll are handled when they connect to that larger tax picture.
Business Tax
S corporation, partnership, Schedule C, and personal tax work for business owners where payroll, books, estimates, and entity decisions all need to line up.
Nonprofit Tax and Compliance
Form 990-series preparation, missing filings, exemption applications, reinstatement support, and exempt-status review.
Notices and Corrective Work
IRS or state letters, missing filings, amendments, and account issues that need the history read before anyone guesses at the fix.
04Complex Individual Tax
Owner returns, K-1s, rentals, investments, retirement activity, prior years, and multistate filing questions.
05Bookkeeping and Payroll
Reliable records and payroll support tied to business tax relationships.
Principal
Jonathan Nesmith, EA
Jonathan works directly on the tax judgment, return review, planning, and significant decisions inside accepted engagements.
His background combines federal tax practice with accounting and operational finance experience, which matters when the return depends on payroll, owner activity, bookkeeping, prior filings, or an agency notice.
