How reducing balances are created

A reducing balance requires:

• An initial amount
• A deduction type (fixed or percentage‑based)
• A Company Pay Element (CPE) that uses the Amount calculation type

Deductions are then taken automatically every pay run.

How they appear on payslips

Payslip side

Depending on the Company Pay Element used:

• Payments CPE: appears on the payment side as a negative value
• Deductions CPE: appears on the deduction side as a positive value

Tax & NI behaviour

The reducing balance inherits the tax/NI/pension rules of the chosen CPE.

Deduction types

1. Fixed Amount

A set amount is deducted every pay run until the balance reaches zero.

If insufficient pay is available:

• The deduction is capped at available pay
• The payslip is flagged with Reducing balance capped

2. Percentage of Gross Pay for Tax

• Enter the % as the “Deduction amount”
• Taken once gross pay for tax is calculated
• Only calculated once per pay run

Example:

Gross pay for tax = £1000
Reducing balance = 25%
Deduction = £250
New taxable gross = £750

3. Percentage of Gross Pay for NI

Works the same as above but uses gross pay for NI.

4. Percentage of Net Pay

• Enter the % as the “Deduction amount”
• Based on net pay (after tax, NI, student loans, pensions, pre‑net deductions & deduction orders)
• The CPE must not be subject to tax, NI or pension calculations

Multiple reducing balances

If multiple balances exist:

• They are taken one after another
• Ordered by start date, then remaining balance

This ensures predictable deduction sequencing

Lifecycle management

A reducing balance can be in one of three states:

1. Active - deductions continue
2. Paused - no deductions taken
3. Closed - no deductions taken; removed from reports

Balances are editable until:

• At least one deduction has been taken and
• The relevant pay run has been completed

After this, key fields are locked for audit integrity.

Reporting

Use the Reducing balances report (in Employee Reports) to view:

• Current active balances
• Remaining amounts
• Deduction history
• Status (Active, Paused)

Ideal for audits, reconciliation, and employee queries.

Recommended setup process

1. Identify purpose

eg overpayment recovery, loan, equipment purchase

2. Choose the correct CPE

• Must use “Amount” calculation type
• Ensure correct tax/NI/pension behaviour
• For % of net pay → the CPE must be non-taxable

3. Configure the reducing balance

• Initial total
• Deduction type (fixed or %‑based)
• Start date

4. Communicate with the employee

• Explain the deduction schedule
• Provide expected payoff date

5. Run payroll as normal

• System automatically deducts the correct amount
• Capping logic applies if needed

6. Monitor via reports

• Check reducing balance status
• Confirm when balance reaches zero

Best practice tips

Use fixed amounts for predictable repayment

Best for loans or equipment purchases.

Use percentage methods for variably-paid workers

Especially where pay fluctuates (overtime, variable hours).

Keep CPE tax/NI rules simple

Avoid complex calculation types—reducing balances require clean inputs

Review balances quarterly

To ensure paused or outdated balances are managed correctly

Communicate changes early

Especially if a deduction will be capped or extended due to low pay
