Common confusion points

Self‑employment vs. employee tax

Many think W‑2 wages are included

→ Verify only Schedule C/F/K‑1 earnings count

92.35% factor usage

Some calculators use 92%

→ Use the exact 0.9235 multiplier

Wage base limit

The limit changes yearly

→ Check the IRS wage‑base table for the filing year

Additional Medicare surtax

Applies only above $200k (single)

→ Confirm income level before adding 0.9%

Deductible part of self‑employment tax

Often omitted on Schedule 1

→ Ensure you claim the deduction if filing Schedule 1
