Combine platforms once, then reconcile
Add DoorDash, Uber, Uber Eats, and Lyft gross receipts as separate inputs. The model sums those entries once; it does not add a 1099, an annual summary, and a bank deposit as separate income.
Use the resulting total with the multi-app records checklist in /guides/multiple-gig-app-taxes/.
Mileage and tax layers stay separate
A standard-mileage deduction lowers modeled Schedule C profit but is not a cash expense. Enter nonvehicle cash costs separately, then review the /mileage/standard-vs-actual/ comparison before selecting a method.
Self-employment tax, federal income tax, and a disclosed state proxy are shown as different layers.
Use the result as a planning checkpoint
The 1099 tax calculator is narrower and focuses on one reconciled 1099 planning flow. This tool is for a driver with multiple apps or multiple 1099 streams.
Frequently asked questions
Should I add each 1099 together?
Reconcile each form to gross receipts, then enter each platform once. Do not add forms, statements, and deposits as separate income.
Can the calculator file Schedule C?
No. It models the arithmetic and records needed for a conversation; it does not generate a tax return.
Are mileage deductions cash expenses?
No. Standard mileage is a noncash tax deduction and must not be subtracted again as fuel or maintenance cash.
