Home health care businesses structured as sole proprietorships, partnerships, LLCs, or S-Corps may qualify for the Qualified Business Income (QBI) deduction under IRC §199A — a 20% deduction on net business income. For a home care agency generating $200,000 in net profit, this deduction alone saves $14,800 in federal taxes. Home health care is generally NOT classified as a Specified Service Trade or Business (SSTB), which means the income limitation phase-out that applies to doctors and lawyers typically does not apply — making this deduction available at higher income levels.
A home health care agency owner with $250,000 in net business income takes a $50,000 QBI deduction, saving $18,500 in federal taxes at 37%.
