What payroll in Fintra does
Payroll is the one finance process where a mistake shows up in someone’s bank account. Fintra runs every paycheck through a verified tax engine covering federal and state calculations, so withholdings are computed consistently and checked before any run is approved. And because payroll lives inside your finance OS, each run posts to the general ledger automatically - no journal entries to rebuild from a provider’s report.
- Verified tax engine for federal and state withholding calculations
- Every run auditable: inputs, calculations, approvals, and outputs preserved
- Salaried, hourly, bonus, and commission pay in the same run
- Automatic GL posting with department-level payroll cost allocation

How it works
From setup to a closed run
- 1
Set up once
Add employees, pay schedules, and state withholding details; the tax engine validates the configuration as you go.
- 2
Build the run
Fintra assembles the run from salaries, approved hours, bonuses, and approved commission payouts automatically.
- 3
Verify calculations
The verified tax engine computes federal and state withholdings and surfaces anything unusual against prior runs.
- 4
Approve and pay
A named approver reviews the run summary and exceptions, then approves; nothing is paid without sign-off.
- 5
Post and archive
The run posts to the GL with department allocations, and the full calculation record is archived for audit.
Auditable by construction
Every payroll run in Fintra is auditable end to end: the inputs used, the tax engine version that computed each withholding, the exceptions raised, and the approver who signed off. AgentFence policies keep AI in a preparation role - assembling runs and flagging anomalies - while approval and payment release remain human decisions recorded in the SentriAI audit trail.
What each run preserves
- Employee-level inputs: pay rate, hours, bonuses, and commissions included
- Federal and state withholding calculations with the engine version used
- Exceptions flagged and how each one was resolved
- Approver identity and timestamp for the run and any off-cycle adjustments
When to adopt it
- You’re paying a payroll provider plus an accountant to re-enter what the provider did
- Commission or bonus payouts keep forcing manual off-cycle runs
- You operate in multiple states and want withholding logic you can actually inspect
- An audit or diligence process is coming and payroll records need to hold up
Frequently asked questions
Does Fintra payroll file taxes for me?
Fintra’s verified tax engine computes federal and state withholdings for every run and prepares the figures behind your payroll tax obligations, with each calculation preserved for audit. Review and approval always sit with a human, so you keep control over what is submitted and when.
What does a verified tax engine mean?
It means withholding calculations are produced by an engine whose logic is tested and versioned - not a spreadsheet or an opaque provider report. Every run records which engine version computed each withholding, so you can reproduce and defend any paycheck’s math months later.
Can Fintra handle employees in multiple states?
Yes. The tax engine covers federal and state calculations, and each employee’s state withholding setup is validated during onboarding. When someone moves or you hire in a new state, the run flags the configuration change so it is confirmed before the next payday rather than discovered after it.
How do commissions get into payroll?
Approved commission runs from Fintra’s sales commission module flow directly into the next pay run - no re-keying from a spreadsheet. Each rep’s payout arrives with its calculation history attached, so payroll, commission statements, and the general ledger all agree by construction.
