According to Alight's 2024 Payroll Complexity Report, over 53% of companies have incurred payroll penalties in the last five years for non-compliance. Behind the seemingly simple word "commission" lies a complex web of legal requirements spanning taxes, vacation pay, GDPR, and pension. The mistakes aren't just expensive. They can also damage trust between company and employee.
| Statistic | Impact |
|---|---|
| 53% of companies | Have incurred payroll penalties in last 5 years |
| 33% of employers | Make payroll errors costing billions annually |
| 40% of SMBs | Fined for tax filing errors |
This guide covers the key compliance areas companies need to master when paying commission. For businesses operating internationally or considering expansion, understanding these principles is essential for building robust compensation systems.
The first and most fundamental point: Commission is taxed as regular income. This means standard payroll taxes and withholdings apply. There are no special rules or exceptions.
| Requirement | Description |
|---|---|
| Tax treatment | Same as regular wages |
| Withholding | Standard payroll taxes apply |
| Reporting | Same as all other wages |
| Nil returns | Mandatory even without payouts |
Employers must report commission just like all other wages. It sounds simple, but statistics show it often goes wrong. According to IRS data, 33% of employers make payroll errors that cost billions of dollars annually. Incorrect timing, wrong classification, or missing reports can result in back payments and penalties.
Particularly problematic is the failure to file nil returns. If you have nothing to report in a given month, you still need to file. Otherwise, you risk penalties for each missing submission. It may not sound like much individually, but it adds up quickly.
This is where things get complicated. Commission-based employees may be entitled to vacation pay calculated on their earned commission if they lose income while on vacation. The keyword is "if."
The right to vacation pay on commission depends on a specific assessment. If the commission requires physical presence, as is the case for a car salesperson for example, the employee typically has the right to compensation. The employee must document that they actually lose income by taking vacation.
This means in practice that a salesperson may be entitled to both regular vacation pay and vacation compensation on commission. It's a nuance many companies overlook because they assume vacation pay covers everything.
Keep track of when commission is earned versus paid out, as this affects the calculation.

Book a demoSocial security contributions are mandatory and typically calculated based on hours worked, not on commission amounts. These obligations apply regardless of how much commission the employee earns.
| Contribution type | Calculation basis |
|---|---|
| Social security | Hour-based, not commission-based |
| Applicability | Mandatory for all employees |
| Cost planning | Must be factored into compensation costs |
The contribution isn't affected by how much commission the employee earns. It's typically hour-based. But it's still an expense that must be factored in when planning compensation costs.
Pension on commission may not be legally required in all jurisdictions, but it's often mandatory through collective agreements or company policies. Typical pension contributions range from 12-18% of salary, with varying splits between employer and employee.
| Pension requirement | Details |
|---|---|
| Typical contribution | 12-18% of salary |
| Key question | Is commission included in calculation basis? |
| Limitation period | 5+ years for back-payment claims |
The crucial point is to check whether commission is included in the calculation basis. This varies between agreements. Some include all variable pay, while others only cover base salary.
A common mistake is forgetting pension on commission, even when agreements require it. This can result in back-payment claims going back several years. Standard limitation periods vary, but claims can stretch back 5 years or more.
Commission data is personal data. Your payroll system is a data processor, and your company is the data controller. This requires a data processing agreement with your payroll provider.
| GDPR risk | Potential fine |
|---|---|
| Maximum fine (GDPR Art. 83) | 20 million EUR or 4% of global turnover |
| Actual fines issued | Range from modest to over 1 billion EUR |
Penalties for data protection violations can be massive. According to GDPR Article 83, fines can reach up to 20 million euros or 4% of global turnover, whichever is higher. Regulators have issued fines ranging from modest amounts to over 1 billion euros depending on the severity.
Employees have the right to insight into how their pay data is processed. They can ask to see who has access to their commission data, how long it's stored, and how it's protected.
A spreadsheet with commission calculations sitting on a shared folder without access control is a compliance problem. A dedicated commission system with role-based access is part of the solution.
Accounting laws typically require 5-7 years of retention for financial records, including pay documentation. Data protection laws require that personal data only be stored as long as necessary. How do you balance this?
| Regulation | Retention period |
|---|---|
| Accounting laws | 5-7 years (minimum) |
| Data protection (GDPR) | Only as long as necessary |
| Recommendation | Retain per accounting law, then delete |
The solution is to retain for the required period under accounting law and then delete, unless there's other legal basis for continued retention. Document your decision so you can explain it in case of an audit.
This also means you need to track when data should be deleted. A manual system makes this nearly impossible to maintain. Automation helps.
Based on regulatory audits and industry experience, here are the most common mistakes:
| Pitfall | Consequence |
|---|---|
| Vacation pay errors | Missing vacation compensation on commission |
| Incorrect tax reporting | 40% of SMBs fined for filing errors |
| Forgotten pension | Back-payments stretching back years |
| Sick pay without commission | Employees entitled to "usual pay" |
| Termination compensation | Lost commission during notice period |
Vacation pay errors top the list. Many companies don't calculate vacation compensation on commission because they assume regular vacation pay is sufficient. It isn't always.
Incorrect tax reporting is second most common. Bonuses and commission are reported incorrectly or late. According to industry research, audits find that 40% of small and medium-sized businesses are fined for failing to deposit withholdings, miscalculating taxes, or submitting incorrect filings.
Pension is forgotten on commission. Even when agreements require pension on all pay, calculations only include base salary. Back-payment claims can go back many years.
Sick pay without commission is another classic. Salaried employees often have the right to "usual pay" during illness. For commission-based employees, this often means expected commission, not just base salary.
Upon termination, compensation for lost commission during notice periods is forgotten. The salesperson should have had the opportunity to close deals and earn commission. When they're placed on garden leave, they lose that opportunity and may have a claim for compensation.
The consequences can be serious. Back payment of wages can go back many years under certain circumstances. Standard limitation periods vary by jurisdiction, but in special cases claims can extend further.
Penalties for missing reports add up quickly when multiplied by months and multiple employees.
Misclassification of contractors as employees can result in back payment of vacation pay, pension, and social contributions for the entire engagement period. This can amount to significant sums per worker.
Manual commission calculations in spreadsheets significantly increase the risk of errors. According to Alight research, manual intervention is the primary reason for payroll noncompliance and errors. When calculations are done manually, it's harder to document, control, and audit.
A dedicated commission system automates calculations and ensures the same rules are applied consistently. It provides traceability so you can document how each commission is calculated. And it integrates with your payroll system so the transfer to payroll happens correctly.
Automation isn't just about saving time. It's about reducing the risk of mistakes that can cost you dearly in back payments, penalties, and lost trust.
Start with a review of your current practices. Are you calculating vacation compensation correctly on commission? Is commission included in the pension basis as required? Do you have a data processing agreement with your payroll provider?
Then consider investing in a system that automates commission calculation and ensures correct integration with your payroll system. It doesn't just give you compliance. It gives you peace of mind.
