Key Information

a Specified Service Trade or Business (SSTB) is a business primarily involved in providing services within specific fields.

These fields include:

• Health
• Law
• Accounting
• Consulting
• Athletics
• Actuarial science
• Performing arts

Tax Impact

The designation of a business as an SSTB impacts how the Qualified Business Income (QBI) deduction is claimed. When an individual’s taxable income:

• Is below a specific threshold, business income from an SSTB is treated like any other business for QBI deduction purposes.
• Falls within a specific range, the QBI deduction is gradually phased out for business income from an SSTB.
• Exceeds a specific threshold, business income from an SSTB is excluded from claiming the QBI deduction altogether.
