Lohnart (wage type)
What a wage type is, how it controls tax and contribution treatment and why the wage type catalogue decides the quality of every payroll run.
1. What is Lohnart (wage type)?
A Lohnart – wage type – is the smallest building block of payroll: a named and numbered key under which a single component of pay is recorded, calculated and shown. Basic pay, an overtime premium, a benefit in kind, a capital-forming payment, a travel expense reimbursement, an attachment deduction – each of these is a wage type of its own.
What matters is what sits behind the name. Every wage type carries control indicators determining how the amount is treated – whether it is employment income under Section 19 EStG and remuneration under Section 14 SGB IV: taxable or tax-free, subject to social security contributions or not, ongoing pay or a one-off payment, attachable or not, part of total gross pay or a pure net deduction. Payroll does not calculate with descriptions but with these indicators.
The wage type is therefore the place where a technical decision becomes a machine rule. Coding an allowance wrongly produces no error log – it produces a payslip that looks plausible and is nevertheless wrong.
That last sentence is the one that scales badly: a wrong indicator does not affect one payslip but everyone it applies to, for every month since it was set.
2. Origin and development
The term comes from the era of mechanical payroll accounting, when payments had to be numbered for processing. The number was initially a technical necessity; it has remained because it achieves something plain text cannot – it is unambiguous, sortable and stable over years.
With every extension of tax and social security law, further indicators were added. Today a single wage type controls a whole chain: determining gross pay, calculating contributions and tax, presentation on the payslip, hand-over to social security reporting and into financial accounting.
3. Core principles and how it works
One component, one wage type
What behaves differently in law belongs on separate wage types – even where it looks similar on paper. A tax-free and a taxable travel subsidy are two wage types, not one amount with a note.
Control indicators rather than labels
The label serves the human, the indicators the machine. Whether an amount feeds into the contribution calculation is decided not by the name but by the indicator held against it. Checking a new wage type is therefore always a check of its indicators.
Ongoing pay or a one-off payment
Whether an amount is treated as ongoing pay or as a one-off payment changes the wage tax calculation considerably. One-off payments such as holiday or Christmas pay are taxed differently from monthly pay – that distinction is anchored in the wage type.
Supersede rather than overwrite
Wage types are not overwritten when the law or a collective agreement changes. They are closed off and created anew, so that past payroll runs remain traceable. An audit sees the position of the payroll month, not today's.
4. Who is Lohnart (wage type) relevant for?
- Payroll specialists – the wage type catalogue is their daily tool; maintaining it decides the error rate. - HR managers in smaller companies – anyone introducing an allowance, a bonus or a benefit in kind is at the same time deciding how it is processed. - Management and finance – the accounts of financial accounting and the basis of every workforce cost analysis run through wage types. - Auditors and inspectors – they read payroll through the wage types; their coherence is the first impression of an audit.
5. How it differs from related terms
- Wage type and pay component – the pay component is the agreement in substance, a shift allowance for instance; the wage type is its technical implementation. - Wage type and cost centre – the wage type says *what* is paid, the cost centre says *for what*. They are kept separately and brought together only in reporting. - Wage type and posting account – every wage type is directed to an account in financial accounting; that mapping is part of the configuration, not of the wage type itself. - Wage type and occupational code – the occupational code describes the person and their work for social security reporting, the wage type the individual payment.
6. Variants and adaptations
- Predefined standard wage types – maintained by the system provider and updated on changes in the law. They cover the normal case. - Customer-specific wage types – for allowances, bonuses and special cases the standard does not contain. They arise during configuration and are the responsibility of the business or its payroll provider. - Collectively agreed wage types – derived from a collective agreement, often with calculation rules of their own, in construction for instance. - Calculating and statistical wage types – the latter pay nothing out but collect values for reporting, provisions or social security returns.
7. Advantages and challenges
Advantages
- Every pay component is separately named, calculable and checkable
- Tax and contribution treatment is held once rather than decided afresh each month
- Reporting and postings arise from payroll without a second data entry
- A clean catalogue makes payroll traceable for auditors
- Special cases can be represented without diluting the standard
Challenges
- A wrongly set indicator produces not an error but a wrong result
- Catalogues that have grown over time often contain duplicates and long-unused wage types
- Changes in law and collective agreements require ongoing maintenance, not one-off configuration
- On a change of system, mapping old to new wage types is the most demanding step
- Without documentation, after a change of staff nobody knows why a wage type is configured as it is
8. Best practices for implementation
Document the catalogue, do not merely maintain it
Every customer-specific wage type deserves a short note: what it applies to, what it rests on and who requested it. At the next audit or the next change of staff that note is worth more than the wage type itself.
Check new wage types before their first use
A new wage type is not introduced in a live run but calculated through on a sample case beforehand and read back by a second person. The effort is small; correcting an error across several months is not.
Clear out regularly
Wage types not posted to for years belong deactivated rather than deleted – that keeps old payroll runs readable and the active catalogue manageable.
9. Tips for employers and employees
For employers
- **Think about payroll before making the promise** – anyone agreeing a new allowance should settle its tax and contribution treatment first
- **Do not let the catalogue proliferate** – creating a separate wage type for every special case makes payroll unusable over time
- **Do not let the knowledge rest with one person** – the configuration belongs documented, not remembered
- **Where a collective agreement applies, coordinate early** – collectively agreed components often need their own calculation rules and lead time
For employees
- **Read your payslip** – every line is a wage type; unclear items can be asked about specifically
- **Expect different tax on one-off payments** – they are taxed differently from ongoing pay, so the net differs accordingly
- **Raise changes promptly** – a wrongly coded component is easier to correct within the year than afterwards
10. Conclusion
The wage type is the least conspicuous and at the same time most consequential building block of payroll. It decides how an amount is taxed, charged with contributions, presented and posted – and it does so silently, without asking. A maintained, documented and regularly reviewed wage type catalogue is therefore not busywork but the basis on which payroll does not merely look plausible but is right.
For an international group two consequences follow. A wrong indicator produces a systematic error rather than a visible one, working across everyone affected and every month since it was set – which is why a second pair of eyes before first use is cheap compared with the correction. And in a payroll consolidation, mapping the existing catalogue onto the new system is regularly the largest single piece of work, and the one most often left out of the plan.
