Precision Payroll.
Powered by Intelligence.

Space HR's AI payroll engine uses machine learning trained on millions of payroll transactions to establish baseline patterns for each employee. Before every run, it compares current data against historical averages, flagging deviations greater than 5% in base pay, sudden overtime spikes, duplicate payment entries, and unauthorized rate changes. All anomalies are presented for HR review before the payroll is finalized and ACH files are generated.

A NACHA-compliant ACH file follows the exact formatting standards set by the National Automated Clearing House Association for electronic fund transfers. Payroll direct deposits that don't conform to NACHA standards will be rejected by banks, causing delayed payments. Space HR automatically generates NACHA-compliant ACH files with proper record formats, routing number validation, batch totals, and file hash checks — ensuring every direct deposit is processed on time without manual file preparation.

The gross-to-net calculation pipeline in Space HR processes each employee's pay in a defined sequence: starting from gross wages (base + overtime + bonuses + commissions), it applies pre-tax deductions (401k, HSA, FSA), calculates federal income tax withholding, then state/local income taxes, FICA contributions (Social Security 6.2% + Medicare 1.45%), FUTA employer tax, and finally post-tax deductions (Roth 401k, wage garnishments, voluntary deductions) to arrive at net pay. The AI auditor verifies every step against current IRS tables before payroll is finalized.

Space HR automatically calculates FUTA (Federal Unemployment Tax Act) at the standard employer rate of 6.0% on the first $7,000 of each employee's wages, applying the 5.4% credit for timely state tax payments to reach the effective 0.6% rate. For SICA/SUTA (State Unemployment Tax), the system applies your state-specific experience rate and wage base limits automatically. All calculations are logged in the liability ledger for audit readiness and financial reporting.

The liability ledger tracks all payroll obligations your organization owes but hasn't yet remitted — including accrued wages, federal/state tax liabilities, FICA, FUTA, benefits payable, and garnishments. Space HR maintains a real-time liability ledger that updates after every payroll run, reconciles against actual disbursements, and generates audit-ready balance reports. This ensures your books are always accurate for financial reporting and tax filings.

Yes. Space HR handles payroll across all 50 US states, managing state income tax withholding, SUTA rates, local payroll taxes, reciprocity agreements, and varying pay frequency requirements. The AI compliance engine automatically updates when tax rates change, so you're always processing with current rules — without any manual configuration.
