Most HRMS pricing pages list “multi-country payroll” next to a checkmark. Most actually delegate non-home payroll to a partner network — meaning a separate vendor, a separate contract, and reconciliation work for your finance team. Real multi-country payroll is rare because each country’s rules are non-trivially different.
What makes a country ‘hard’
- A statutory deduction model that updates yearly (slabs, thresholds, surcharges).
- Mandatory filings to a government portal with prescribed file formats (ECR, P11D, 941).
- A payslip format expected by employees and possibly by law.
- Bank disbursement file formats specific to local banking rails (NACH/NEFT in India, ACH in US, BACS/Faster Payments in UK).
India payroll — the spine
The deepest statutory surface of the three. Provident Fund (12% + 12%, ECR file by 15th), ESI (0.75% + 3.25% if applicable), professional tax that varies state to state, TDS with old vs new regime, Section 87A rebate logic, surcharge tiers, health & education cess. Form 16 generation requires the quarterly 24Q filing first. Gratuity needs actuarial provisioning for the P&L.
US payroll — federalism is the difficulty
- Federal withholding from W-4 forms; updated IRS withholding tables yearly.
- FICA — Social Security (6.2% up to the wage base, $168,600 for 2024) + Medicare (1.45%, plus 0.9% additional Medicare above $200K).
- State + local withholding — varies dramatically. California has its own tables; Texas, Florida, Washington have no state income tax. Local (city) tax in some states.
- State unemployment (SUTA) rates that vary by employer.
- 401(k) pre/post-tax, employer match, vesting schedules.
- Forms: 941 quarterly, 940 annual, W-2 by January 31.
UK payroll — HMRC’s real-time
- PAYE — income tax via tax codes (1257L is the standard). Real-Time Information (RTI) submission on or before every payroll run.
- National Insurance Contributions (NIC) — employee Class 1 + employer Class 1 at varying rates based on earnings bands.
- Pension auto-enrolment at minimum 3% employer + 5% employee contribution.
- Student loan deductions by plan type (Plan 1, 2, 4, postgraduate).
- Statutory sick, maternity, paternity pay with recoverable portions.
- P60 annually by 31 May; P11D for benefits by 6 July.
Why running them on one platform matters
Two reasons that compound:
- Single source of truth for the employee record. An engineer in Bangalore and a designer in London should be the same record — not duplicated across an Indian payroll tool and an UK provider with different IDs.
- Consolidated finance close. Finance wants one payroll line per period across all geographies, not three reconciliations.
The architectural pattern
The clean approach is a pluggable country-engine pattern: one shared payroll service that delegates statutory + filing logic to a per-country module. India, US, and UK each get their own engine file that knows that country’s rules; everything else (employee model, employment lifecycle, salary structures, approvals, audit) is shared.
VeloHR is built this way — India engine shipped first with full statutory depth, US and UK engines now live on the same data plane. One tenant can run all three in parallel with one period close. Compare against partner-network HRMS pricing pages: ask whether non-home payroll is delivered by the same company, on the same database, with the same support team.
