Payroll audits can be costly, time-consuming, and disruptive. They often involve retrospective reviews of payroll records, statutory filings, and employee documentation, and can result in additional tax liabilities, penalties, and interest if issues are identified.
In Kenya, many payroll audits are triggered by specific payroll errors and reporting patterns rather than intentional tax evasion. Understanding these triggers can help you identify risk areas early and reduce the likelihood of audit escalation.
This article explores the payroll issues that commonly lead to KRA audits in Kenya and highlights practical steps employers can take to reduce audit risk.
How KRA Identifies Payroll Audit Risks
KRA identifies payroll audit risks by analysing payroll data for inconsistencies, unusual patterns, and deviations from expected reporting behaviour. This analysis typically involves cross-checking payroll data against:
- PAYE returns and payment histories
- Statutory deductions submitted to other agencies
- Historical payroll trends
- Bank payment patterns
- Employer size, sector, and industry benchmarks
When inconsistencies or unusual patterns are detected, KRA may issue a query or initiate a payroll audit. However, most audits arise from repeated, unexplained, or inconsistent payroll patterns rather than isolated errors.
Payroll Errors That Commonly Trigger KRA Audits
Below are the payroll errors that commonly lead to KRA payroll reviews and audits.
PAYE Miscalculations and Under-Remittance
PAYE miscalculation occurs when the amount of tax deducted from employees’ salaries is incorrect, resulting in either over-deduction or, more critically, under-deduction. These errors typically arise from:
- Applying outdated tax bands or rates
- Incorrect application of personal relief
- Errors in taxing overtime, bonuses, or commissions
- Manual payroll calculations without adequate checks
Over time, repeated PAYE under-deductions signal potential revenue loss to KRA and are therefore treated as a high-risk compliance issue.
Where PAYE is under-remitted, KRA may assess the unpaid tax retrospectively and impose penalties and interest on the outstanding amounts. The audits can extend across several years, and employers may be required to pay the shortfall even if the error was unintentional.
Late or Inconsistent Statutory Remittances
Late statutory remittance refers to failure to submit PAYE and other payroll-related deductions within the prescribed timelines. Inconsistency occurs when remittances fluctuate without clear explanations or fail to match declared payroll figures.
While occasional delays may occur, repeated late payments suggest weak payroll discipline and poor compliance controls. It increases the likelihood of queries or audits, particularly where delays occur across multiple tax periods.
Late remittances attract statutory penalties and interest, which continue to accrue until payment is made. Persistent non-compliance may also prompt KRA to conduct a broader payroll audit to assess overall compliance.
Payroll Records That Do Not Match iTax Submissions
This error arises when payroll records, PAYE returns filed on iTax, and actual salary payments do not reconcile. For example, payroll registers may show higher gross pay than what is declared on iTax, or the PAYE declared may not correspond with net salaries paid.
Such discrepancies often result from:
- Post-payroll adjustments
- Incomplete reconciliations
- Corrections made after returns have already been submitted.
From KRA’s perspective, mismatches raise questions about accuracy, transparency, and whether payroll figures have been deliberately altered.
If inconsistencies are identified during an audit, KRA may reassess PAYE liabilities and impose additional tax assessments, penalties, and interest.
Employee and Contractor Misclassification
Employee misclassification occurs when individuals who should legally be treated as employees are classified as independent contractors, or vice versa. A common example is paying regular staff through invoices instead of payroll to avoid PAYE obligations.
Misclassification often results in payroll figures that appear inconsistent with business operations. For example, PAYE may appear unusually low relative to staff activity, or payment volumes may not align with declared payroll costs.
These inconsistencies can surface during routine data analysis. When they do, KRA may examine contracts, payment frequency, levels of control, and the nature of the working relationship to determine whether PAYE should have been applied.
Where misclassification is established, KRA may assess backdated PAYE for the affected periods, together with penalties and interest.
Incorrect Treatment of Allowances and Benefits
This error occurs when taxable allowances or non-cash benefits are treated as non-taxable, resulting in under-declared PAYE. Common examples include housing allowances, transport allowances, bonuses, or employer-provided benefits that are either partially taxed or omitted entirely.
These errors often stem from misunderstandings about what constitutes taxable income or inconsistent treatment of allowances across payroll periods. Because allowances can materially affect taxable pay, incorrect treatment is a frequent audit trigger.
If your allowances are under-taxed, KRA may issue additional PAYE assessments, together with penalties and accrued interest. Employers are typically held responsible for the unpaid tax, even where employees benefited from the error.
Poor Payroll Record Keeping
Poor payroll record keeping refers to the absence, incompleteness, or disorganisation of payroll documentation, including:
- Payslips
- Payroll registers
- Contracts
- Statutory payment records
Even where PAYE is calculated and paid correctly, the inability to produce supporting records creates compliance risk. KRA audits rely heavily on documentary evidence, and missing records can prevent employers from substantiating their payroll positions.
Inadequate records can lead to estimated assessments, penalties for non-compliance, and prolonged audits. You may also incur additional professional costs while reconstructing historical payroll data.
Behavioural Red Flags That Escalate Payroll Reviews
Beyond technical payroll errors, KRA also evaluates patterns of behaviour that indicate elevated compliance risk. These behavioural red flags do not automatically imply wrongdoing, but when they occur repeatedly or alongside payroll errors, they increase the likelihood that a payroll review escalates into a full audit.
Frequent Amendments to PAYE Returns
Frequent amendments occur when an employer repeatedly revises PAYE returns after submission. While occasional corrections are expected, regular amendments suggest weaknesses in payroll accuracy, reconciliation processes, or internal controls.
From KRA’s perspective, repeated changes to filed returns reduce confidence in the reliability of payroll data. This often leads to closer examination of payroll calculations and may prompt KRA to review multiple prior periods to establish whether under-declaration has occurred.
Sudden Unexplained Changes in Payroll Costs
Sharp increases or decreases in reported payroll costs without a clear operational explanation are a common audit trigger. KRA systems analyse payroll trends over time and compare them against historical patterns.
Where changes cannot be reasonably linked to factors such as staffing adjustments, business expansion, or seasonal activity, payroll figures may be flagged for review. Unexplained fluctuations often raise concerns about omitted income, inconsistent reporting, or incorrect classification of payments.
Payroll Figures Inconsistent With Business Size or Activity
Payroll data that does not align with the scale or nature of a business can attract scrutiny. For example, a company reporting high turnover but unusually low payroll costs may appear inconsistent with industry norms.
KRA uses comparative analysis to assess whether payroll figures reasonably reflect the business’s operations. Significant inconsistencies may suggest worker misclassification, incomplete payroll reporting, or under-declared PAYE.
Repeated Penalties for Late Filings or Payments
Consistent penalties for late PAYE filing or payment indicate ongoing compliance weaknesses rather than isolated errors. Over time, this pattern signals that payroll obligations may not be managed systematically.
KRA may view repeated penalties as an indication that other aspects of payroll compliance could also be deficient, increasing the likelihood of an audit.
Combined Effect of Multiple Red Flags
While a single behavioural red flag may not lead to further action, multiple red flags occurring together significantly increase audit risk. When behavioural patterns align with payroll errors or record-keeping gaps, KRA is more likely to initiate a comprehensive payroll audit to assess overall compliance.
What Happens When Payroll Triggers a KRA Audit?
When payroll issues are identified, KRA does not usually proceed directly to a full audit. In many cases, the process begins with a query letter requesting clarification, corrections, or supporting documentation relating to specific payroll periods. These initial queries are intended to confirm whether identified inconsistencies can be resolved without further action.
If responses are incomplete, inconsistent, or reveal broader issues, KRA may escalate the matter into a formal payroll audit. At this stage, the scope of review typically expands beyond isolated errors to cover payroll practices over multiple tax periods.
During a payroll audit, KRA commonly requests documentation such as:
- Payroll registers covering several years
- PAYE returns and corresponding payment confirmations
- Employee contracts, payroll schedules, and staff listings
- Supporting records for allowances, benefits, and deductions
The audit process focuses on verifying whether PAYE and other payroll-related obligations were accurately calculated, correctly reported, and paid on time. Where discrepancies are confirmed, KRA may issue additional tax assessments, together with penalties and accrued interest.
Even in cases where no additional tax is ultimately assessed, payroll audits can be time-consuming and operationally disruptive, particularly where records are incomplete or poorly organised.
How To Reduce Payroll Audit Risk
Reducing payroll audit risk requires more than meeting filing deadlines. The table below highlights some practical measures.

FAQs
1. Does a payroll error automatically trigger a KRA audit?
No. Isolated errors do not usually trigger audits. However, repeated, unexplained, or inconsistent payroll errors significantly increase the likelihood of queries and audit escalation.
2. How far back can KRA review payroll records during an audit?
KRA payroll audits often cover multiple prior tax periods, especially where systemic issues are suspected. Employers are expected to retain employment records for at least 5 years and tax records for at least 7.
3. Are employers liable for PAYE errors even if they were unintentional?
Yes. Employers remain responsible for correct PAYE calculation and remittance. Where under-deductions occur, KRA may assess backdated tax, penalties, and interest regardless of intent.
