Accounting & Tax Services in York, PA

York has been a manufacturing powerhouse since the Industrial Revolution, and today York County remains one of Pennsylvania’s strongest manufacturing economies. Harley-Davidson operates its Vehicle Operations and Powertrain Operations plants on Eden Road, while BAE Systems produces military vehicles and turrets at its York facility for the U.S. Army. Voith Hydro, Graham Packaging, and Dentsply Sirona maintain significant manufacturing operations throughout the county, creating a deep supplier network of machine shops, metal fabricators, and precision component makers along the North George Street industrial corridor and the Loganville-Shrewsbury manufacturing belt. York County’s agricultural sector produces dairy, poultry, and grain across 2,300 farms, blending rural farming with suburban growth in communities like Dallastown and Red Lion. Defense manufacturing requires DCAA-compliant cost accounting, job costing by contract, and controlled unclassified information handling. SDO CPA serves York business owners in manufacturing, defense subcontracting, and agriculture with expertise in manufacturing cost accounting, job costing for defense contracts, heavy equipment and machinery depreciation, and agricultural tax provisions for York County farming operations. For Harley-Davidson suppliers managing just-in-time production costs or defense subcontractors tracking per-unit pricing for military orders, we provide bookkeeping and tax planning designed for York’s manufacturing heritage.

Pennsylvania Tax Planning Tip

Pennsylvania’s flat 8.99% corporate net income tax is among the highest in the U.S., but pass-through entities like S-Corps and partnerships are taxed at the individual level at a flat 3.07% personal income tax rate. Choosing the right entity structure can significantly reduce your state tax burden. Philadelphia businesses must also account for BIRT and the city wage tax, which adds another layer that proper planning can minimize.

York is home to 1,800+ small businesses and a population of 45,355. From Manufacturing, Defense, Agriculture to professional services, York business owners need CPAs who understand Complex manufacturing cost accounting and defense contract compliance for York County’s heavy industrial and military supplier base and can provide year-round tax planning — not just compliance.
