Schedule SE · Business tax planning
Self-employment tax, connected to the profit that creates it.
Schedule C Line 31 is not the whole tax story. GlidePath starts from business net profit, applies the self-employment tax rules, coordinates the Social Security wage base with W-2 wages, applies the Social Security, Medicare, and 0.9% Additional Medicare pieces, and shows the half-SE deduction and the Schedule SE / Form 8959 trail your preparer confirms.
Designed for planning and review, not filing.
Quarterly tax planning breaks when SE tax is just a flat guess.
W-2 wages can use up Social Security wage-base room. Medicare has no equivalent cap. Additional Medicare can appear later. A flat percentage hides all of that.
GlidePath keeps the pieces visible so the household cash-flow plan, business tax set-aside, and accountant pack all tell the same story. The output is still a planning estimate; the filed Schedule SE belongs with the preparer.
The review path is the feature.
From profit to net earnings
The estimate starts from Schedule C net profit and makes the net-earnings step visible before Social Security and Medicare are calculated.
W-2 coordination is explicit
W-2 Social Security wages reduce the remaining OASDI room. Medicare stays uncapped and the 0.9% Additional Medicare is called out on its own, because they do not behave the same way.
Accountant-pack ready
The same Schedule C base feeds the business view and the accountant pack, so the SE-tax estimate can be reviewed alongside the income and expense lines that produced it.
GlidePath estimates self-employment tax for planning and review. It is not tax advice and does not file Schedule SE or Form 8959. Confirm the final return treatment with a qualified tax professional.
Self-employment tax questions
Can GlidePath estimate self-employment tax from Schedule C profit?
Yes. It starts from Schedule C net profit, applies the net-earnings factor and filing floor, then applies the 12.4% Social Security (coordinated with W-2 wages), 2.9% Medicare, and 0.9% Additional Medicare pieces and the half-SE-tax deduction for review.
Does it coordinate with W-2 wages?
Yes. W-2 Social Security wages are included as an input because they reduce the remaining Social Security wage-base room, while Medicare continues without the same cap.
Does it file Schedule SE or Form 8959?
No. It shows the planning estimate and hand-off trail. Your preparer confirms the final Schedule SE and any Form 8959 Additional Medicare Tax reporting.
