Small Business Taxes in Dayton, OH

Entity returns and year-round tax work for LLCs, partnerships, S-corps, and C-corps. Federal, state, and local returns prepared end-to-end — plus the planning conversations that actually lower the bill.

Montgomery County is home to a diverse range of business structures — professional-service firms, real estate holding entities, product companies with interstate sales, and contractors who cross state lines regularly. CS Precision Tax prepares entity returns for LLCs, partnerships, S-corps, and C-corps registered or operating in Dayton, Ohio. Ohio's economy — driven by Manufacturing, healthcare, finance, logistics — generates the kinds of multi-state nexus, contract labor, and cross-border transactions that extend filing obligations well beyond a single OH return. We file Form 1065 for partnerships and multi-member LLCs, Form 1120-S for S-corps, and Form 1120 for C-corps — every required schedule, partner and shareholder K-1, and depreciation rollforward included. Top Ohio income-tax rate: 3.50%. We review your full nexus footprint, file every applicable state and local return, calculate defensible reasonable compensation for OH S-corp owners, and model the net economics of an S-corp election — including payroll cost, additional bookkeeping, and the 1120-S fee — before recommending it. Local context: Aerospace, defense, Wright-Patterson AFB, manufacturing.

Ohio's Manufacturing, healthcare, finance, logistics industries regularly involve cross-border transactions, contract labor, and out-of-state property — each can create filing obligations beyond the OH entity return.

Frequently asked questions for Dayton, OH

Does my Dayton-based business need a separate Ohio entity return?
Ohio requires a OH entity return for businesses with nexus in the state. Top Ohio income-tax rate: 3.50%. The state return follows the federal classification — a federal Form 1065 partnership also files a OH partnership return — but applies Ohio's apportionment rules and conformity adjustments. We prepare the federal and OH returns together for clients throughout Montgomery County.
My Dayton LLC sells to customers in other states. Could I owe tax outside OH?
Possibly. Economic nexus is triggered when your sales to another state exceed that state's threshold, which can require a nonresident entity return or franchise tax filing there. Given the reach of Ohio's Manufacturing, healthcare, finance, logistics economy, many Dayton businesses hit out-of-state nexus thresholds earlier than expected. We review revenue by state as part of every entity engagement.
