Secondment Payroll: Host Company Benefit vs Home Employer Salary

Quick answer: During a secondment, identify which employer pays base salary, which organisation provides allowances or reimbursements, and how the assignment terms coordinate them. Do not assume every host-company payment is additional recurring salary. The assignment agreement is the starting point for reconciliation.

What to establish before checking the amount

Home and host organisations may divide responsibilities for cash pay, expenses and benefits. Some amounts may be passed through one payroll for reporting even when paid elsewhere. Cross-border assignments can involve additional tax and legal issues; a payment worksheet should not substitute for assignment-specific professional advice.

Step-by-step check

1. Read the assignment's payment-responsibility schedule. Identify the exact nature of the change before calculating its effect. A system migration, internal transfer, rehire and legal-employer change require different interpretations of the records.
2. List home and host cash and benefit channels. Use effective dates to allocate responsibility. Payment dates alone cannot establish which employer or system owns an earning period or an unresolved correction.
3. Identify amounts reported in one system but paid by another. Check balances as well as current salary. A new payslip can calculate this month correctly while omitting a carried-forward advance, claim or historical cumulative amount.
4. Reconcile each payment with its defined purpose and period. Retain the mapping and the authorised contact for each period. The transition is easier to explain later when the old portal is closed or a payroll team has changed.

Worked example

The home payroll pays ₹50,000 net salary, while the host reimburses ₹8,000 of approved travel expenses. Total receipts are ₹58,000, but the reimbursement should not automatically be described as a ₹58,000 recurring salary. If the home payslip also reports the ₹8,000, check whether an offset prevents a second cash payment.

The example is illustrative. Its dates, amounts and assumed calculation method are not an official salary rate, statutory formula or statement about a particular employer. Replace them with your confirmed records before using the calculation.

Build a transition record across both systems

Create a timeline showing the last period under the old arrangement and the first period under the new one. Record legal employer, employee ID, payroll owner and access route separately. These fields can change independently. A branch move does not necessarily change the legal employer, and a new software login does not by itself reset service or erase an outstanding balance.

Check the opening position in the new system against the closing position in the old one. Relevant items can include cumulative earnings, unpaid adjustments, recovery balances and pending claims. Determine whether each item was migrated, paid off or intentionally left for the old team to settle. Keep the written responsibility split so future queries do not circulate between teams indefinitely. Use authentic transition communications to explain differences in documents rather than editing older statements to resemble the new format.

Records to put beside the calculation

Record	What to note
Official transition or transfer communication	Record the issue date, relevant period and version. Keep the original so a later change remains traceable.
Old and new identifiers and effective dates	Identify the exact approval, rule or identifier that supports this case, rather than relying on a general description.
Closing and opening balance records	Highlight the affected amount or field. Separate confirmed information from any value still awaiting clarification.
Statements and payment records from both periods	Link the outcome to the original reference. Note whether the item is settled, replaced, reversed or still outstanding.

A mistake that can change the result

Do not assume the host's local pay practices override the written assignment terms or applicable rules.

How to raise a focused query

Use the exact statement period and affected item in your request. Attach only the records needed to demonstrate the discrepancy through the employer’s authorised channel. A focused request is easier to resolve than a message asking why the entire salary looks wrong.

Subject: Clarification requested — Secondment Payroll: Host Company Benefit vs Home Employer Salary

Please review the attached record for the stated period. My query concerns the following checks: read the assignment's payment-responsibility schedule; list home and host cash and benefit channels. Please confirm the applicable input or rule, explain the calculation or record status, and identify any correction needed. If the item has already been settled, please provide the linked statement or transaction reference. Please also confirm who owns any remaining action and when I should follow up.

Replace the description with your actual dates, amounts and references before sending. This is a request for clarification, not evidence that the employer has made an error. Keep its acknowledgement with the documents used in your calculation.

Frequently asked question

Who should answer a mismatch involving both organisations?

Ask the designated assignment or payroll coordinator to confirm ownership of the item, using the same period and payment references for both sides.

What a complete resolution looks like

Keep a responsibility matrix so every salary component, benefit and expense has one accountable payer and one settlement record.
