Generate a tax estimate

post

https://api.wingspan.app/v3/finance/tax-estimates

Calculates estimated federal, state, and self-employment taxes from the Account's stored tax profile — filing status, state of residence, and estimated annual income and expenses. Those are inputs to the calculation, not to this request: write them with PATCH /finance/tax-withholdings/settings first, then call this to compute against them. year is the only request field, and it selects the tax year rather than changing the inputs. Nothing is persisted.

Body Params

year

integer

Tax year. Defaults to the current UTC year.

Headers

Idempotency-Key

string

length between 1 and 255

^[\x21-\x7e]{1,255}$

Optional idempotency token for authenticated POST and PATCH requests. Reusing the same key and body returns the cached response for 24 hours, except credential operations that explicitly document a 409 because one-time secret material is never cached; reusing it with a different body returns 409 IdempotencyKeyConflict. Use 1-255 printable ASCII characters.

X-Wingspan-Account

string

^(?:[A-Za-z0-9_.]{22}|[a-f0-9]{24})$

Select the Account for an Account-scoped operation. A direct ServiceAccount API key MUST supply this header, and the target must be within the ServiceAccount owner's or Authorization grant's Account boundary. A Person bearer may select an Account on which it has an active Stakeholder, and an Account session may select its bound Account (or a descendant only when the session explicitly includes descendants).
