How to Extract Data from Payslips Using OCR?

What’s the first thing you do once your salary is credited into your bank account? (Apart from spending it, of course…) 

I immediately rush to review my payslip to understand the earnings and deductions in detail.

In this article, we will understand this document that has become an integral part of our monthly work ritual. 

We will briefly discuss pay slips and their different components and, most importantly, how can employers read or extract data from bulk pay slips with OCR.

What is a payslip

Payslips, commonly called salary slips, are essential documents employers provide to employees. 

These documents give a detailed account of an employee’s earnings and deductions for a given payroll period. Payslips are crucial for both parties, serving as a payment receipt and a record of financial transactions.

Payslips are important for employees for 

• proof of income
• tax filing purposes 
• loan applications to assess financial stability
• resolving discrepancies related to deductions
• personal finance planning

For employers, banks, and businesses, payslips are important for

• salary slip or income verification
• background checks
• compliance with tax forms like W2 (in the U.S.), Form 26AS (in India)
• fraud checks
• record-keeping

Looking to extract or parse data from payslips and W2 forms? Try Nanonets’ OCR extractor.

What is payslip OCR, and what does it do?

It is important to extract and digitize critical information from payslips.

Payslip OCR is a technology that automates text extraction from physical or scanned payslips and converts them into a machine-readable format. 

By utilizing OCR (Optical Character Recognition), the data within payslips can be captured automatically, making the payroll accounting process much easier by facilitating the storage, retrieval, and analysis of employees’ salary slips.

OCR is primarily used in payslip processing to classify payslips, extract key value information from salary slips, and convert scanned pay slips into digital formats.

An advanced OCR captures and accurately extracts different key-value pairs from a salary slip.

A standard payslip typically includes fields such as:

Employee information: Name, employee ID, department of the employee, and social security number

Employer information: Company name, address, and other details

Pay period: Monthly, Bi-weekly, or as per the company’s payroll cycle

Salary period: Number of working days or hours, and leaves taken

Earnings: Salary breakdown, including basic pay, overtime, bonuses, etc.

Deductions: Taxes, insurance premiums, retirement contributions, etc.

Net pay: In-hand amount after all deductions

Year-to-date (YTD) totals: Total earnings and deductions for the current year

Convert payslips

OCR can convert payslips into PDF, TXT/Doc, CSV, XLSX, XML, or JSON formats.

You can use digital payslips in PDF, JPEG, or PNG formats directly received via email or downloaded from your employee portal.

To convert scanned copies of physical payslips into digital payslip formats, you need an advanced, powerful OCR. The scanned pay slip should be clear, well-lit, and distortions-free for the conversion to be accurate.

Benefits and challenges of payslip OCR

Reasons to use payslip OCR

Payslip OCR offers several advantages for both businesses and employees:

Efficiency: It eliminates the time and effort needed to copy and paste entries from hundreds of salary slips on different applications.

Accuracy: Minimizes human errors normally incurred when keying in the data, improving the quality of data.

Convenience: Makes payslips data more accessible by making it easy to locate and retrieve

Cost savings: Eliminates the costs incurred in handling and keeping physical payslips, making the process easier and more efficient.

Integration: Can be integrated easily with accounting, payroll, and HR tools to set up approval workflows.

Scalability: Speedens payslip processing for large companies. 

Challenges for payslip OCR

While payslip OCR is an absolute asset, for it to work best, companies need to overcome some challenges, such as

Low-quality scans

Many payslip parsing tools work only with properly scanned documents. Poorly scanned, blurred, or distorted images and documents in dim lighting are difficult to process for OCR.

OCR tools might have difficulty reading such payslips, frequently resulting in poor extraction and inaccurate results. 

Fraudulent payslips

Companies need to check whether pay slips are authentic. Keep an eye out for 

• pay slips with bent or distorted parts
• low-quality images
• blurred or texts in multiple fonts 

Handwritten payslips

Handwritten scanned payslips are challenging to parse for traditional OCR systems.

Difficult formatting

Payslips differ across employers and countries in formats, currency and designs. Traditional OCR tools or template matching often fall short and are unable to handle these accurately.

Complexity of payslips

Not all OCRs are the same. 

Especially for international companies dealing with multi-language payslips with different templates, the OCR must be robust and powerful to adopt flexible templates and extract key information accurately.

Data security

With a surge in free OCR tools, data security is at a major risk. Payslips include sensitive information about employees and companies. Review the company’s privacy policy before choosing an OCR tool to process pay slips.

Initial training

Some machine learning-based OCR solutions require training to recognize and understand payslip layouts. This can quickly become resource-intensive and expensive, as manual copy-paste method efforts divert into model maintenance and monitoring.
