Swifto ERP · Manual — Payslips (HR & Payroll)

1

Overview

The Payslips screen produces the monthly payslip for each employee. When a payslip is opened, Swifto calculates all the components (prorated gross, CNSS, taxable salary, CSS, IRPP, net); the possible entries (overtime, public holidays, bonuses, fines, advances) recalculate the net in real time. The list is grouped by month.

Business goal

Calculate the compliant net payable
Apply CNSS, CSS and IRPP automatically
Bulk-generate for the entire workforce
Pay and produce the transfer order

Target audience

Payroll manager — generates & adjusts payslips
Accounting — payment & transfers
Declarations — basis for the social reports

Position in the module

The payslip relies on the employee record (marital status, children) and the contract (base pay, work schedule). It then feeds the social declarations.

Payslip detail — gross → net engine

CNSS, CSS & IRPP — the sequence

CNSS

Social security contribution: employee share withheld + employer share (employer charge), calculated on the gross.

CSS

Social Solidarity Contribution: configurable rate applied to the taxable base, then ÷ 12.

IRPP

Income tax by brackets on the annual taxable base, brought to the month (÷ 12).

Calculation sequence

1. Gross = prorated base (days/hours) + overtime + bonuses − unpaid days
2. Employee CNSS + employer CNSS (on the gross)
3. Taxable salary = Gross − employee CNSS (− professional expenses)
4. CSS = rate × taxable, then ÷ 12
5. IRPP = bracket scale (annual) ÷ 12
6. Net = Gross − employee CNSS − CSS − IRPP

The IRPP bracket scale

IRPP is calculated on the annual taxable salary by applying the progressive scale (brackets from the tax table), then divided by 12 for the monthly deduction. The deductions (head of household, children) are deducted before the scale is applied.

The amounts in the screenshots are illustrative examples. The applied CNSS, CSS rates and IRPP scale depend on the tax table in force (configurable per year).

Dependent children — special cases (IRPP)

Before applying the IRPP scale, Swifto subtracts the deductions for dependent children. Two situations qualify for an increased deduction: the disabled child and the child pursuing higher education without receiving a scholarship. The number of children concerned is entered on the employee record.

Substitution, not accumulation

The increased deduction for a disabled child or a child in higher education replaces that child's ordinary deduction — it is not added to it. This is a substitution rule, in accordance with article 40 of the Tunisian IRPP Code.

Worked example — 3 dependent children

An employee has 3 dependent children, including 1 in higher education. Assume an ordinary deduction of 100.000 TND per child per year, and an increased higher-education deduction of 1,000.000 TND per year (illustrative values — see the year's tax table).

• Child 1 (ordinary) ......... 100.000
• Child 2 (ordinary) ......... 100.000
• Child 3 (higher ed.) ...... 1,000.000 ← replaces the ordinary 100.000
Total children deduction = 1,200.000 TND / year

Compare with 3 × 100.000 = 300.000 TND if the 3 children were ordinary. The increase applies only to the child concerned; the other two keep their rank deduction. This total is subtracted from the annual taxable salary before the scale is applied, which reduces the IRPP due.

The same rule applies to a disabled child: their increased deduction replaces their ordinary deduction. Enter the number of disabled children and children in higher education on the employee record; Swifto applies the substitution automatically when calculating the payslip.

The gross↔net simulation available from the employee record uses exactly the same engine as the actual generation.

Generation & payment

Payroll is generated employee by employee or for the entire workforce (bulk generation), then paid and turned into a bank transfer order.

Bulk generation

Entire workforce

Choose the month/year: Swifto produces all the payslips at once. Then adjust case by case if needed.

Payment

Mark as paid

Select payslips then fill in the date, currency and payment account. The status changes to Paid.

Transfer order

Excel export

Produces an Excel file of the multiple transfer order to send to the bank.

PDF payslip

Document

Generates the payslip in PDF (per-row action) to give to the employee.

Payslip statuses

Status	Meaning
Not paid	Payslip generated, net payable awaiting settlement.
Paid	Payslip settled: payment date, currency and account filled in.

Only generated and validated payslips feed the social declarations for the period.

Business rules

IRPP by brackets — the tax is calculated on the annual taxable salary by applying the progressive scale, then divided by 12 for the monthly deduction.

CNSS & CSS — CNSS separates an employee share (withheld) and an employer share (employer charge), both on the gross. CSS applies to the taxable base at a configurable rate, brought to the month.

Child deductions by substitution — a disabled child or a child in higher education has their "raised to" deduction replace (and not add to) their rank deduction. Details on the Employees page.

Simulation = generation — the gross↔net simulation (employee record) and the actual generation use the same engine: no discrepancy.

Tax table — CNSS/CSS rates and IRPP scale depend on the year's tax table. Incorrect configuration distorts all the calculations.

Usage scenarios

Monthly payroll for the entire workforce

Bulk generation for the month → case-by-case review → grouped Payment → Transfer order Excel sent to the bank.

Employee with an advance

An advance for the month is automatically deducted from the net payable of the corresponding payslip.

Overtime

Entering overtime on the payslip increases the gross and instantly recalculates the net.

FAQ & Tips

The calculated net does not match my expectations?

Check the year's tax table (CNSS/CSS rates, IRPP scale) and the dependent children (disabled / higher ed. by substitution).

A bonus / advance does not appear on the payslip?

Make sure it is entered for the same month/year as the payslip, and for the right employee. The field only shows if an amount exists.

How to generate payroll for the entire workforce?

Use bulk generation (icon ) from the list, then adjust case by case if needed.

Tip — check before paying

After a bulk generation, review the atypical payslips (overtime, fines, advances) before launching the payment and the transfer order.
