Key takeaways

• Prioritise payroll software with automated tax calculations and direct filing to government agencies, as small businesses spend a median of 26 hours per year on PAYE tasks alone — time that automation can give back to you.
• Choose cloud-based payroll software that integrates with your existing accounting tools, scales as you hire more staff, and lets you run payroll from any device without needing specialist training.
• Stay on top of compliance by filing employment information within two working days of each payday and keeping accurate payroll records for the required period — seven years in New Zealand, four in the US and UK.
• Budget $20–$100 per month for payroll software and compare pricing models — per-employee, tiered, or bundled — to find the best fit for your business size and the features you actually need.

What is payroll for small businesses

Payroll is the process of paying your employees and managing the taxes and compliance that come with it. This includes calculating wages, withholding taxes, and reporting payments to government agencies.

Payroll matters to your business for two main reasons:

• Legal compliance: accurate payroll helps you meet tax rules and avoid costly adjustments, such as the $1.2 billion in adjustments New Zealand's Inland Revenue made in a single year
• Employee trust: paying your team correctly and on time builds confidence and helps you retain valuable staff

Here's what you need to know about payroll for your small business.

Why small businesses need payroll software

Payroll software saves time and reduces errors by automating the calculations and compliance tasks that come with paying employees. A 2024 study found that small businesses spent a median of 26 hours per year on pay as you earn (PAYE) tasks alone.

With payroll software, you can automate tax calculations, stay compliant with filing rules, and pay your team accurately and on time. That means less admin and more time to focus on running your business.

Key features of payroll software

The right payroll software combines automation, accuracy, and ease of use. When comparing options, look for features that save time and reduce the risk of errors.

Key features to look for include:

• Automated calculations: calculate wages, tax, and deductions without manual data entry
• Automated filing: submit payday filing directly to tax authorities without extra steps, which is especially crucial since established employers must file electronically if their total annual PAYE and employer superannuation contribution tax (ESCT) is $50,000 or more
• Accounting integration: sync payroll data with your accounting software to keep records consistent
• Employee self-service: let employees view pay slips, update personal details, and access tax forms online
• Mobile access: run payroll from anywhere using a phone or tablet
• Direct deposit: pay employees directly into their bank accounts on payday
• Real-time reporting: track payroll costs, tax obligations, and compliance status at a glance
• Timesheet integration: import hours worked directly into payroll for hourly employees

How to choose the right payroll software

Payroll software comes in two main formats: integrated accounting solutions and standalone applications. Choose based on your business size, complexity, and existing systems.

When evaluating payroll software, consider these criteria:

• Check integration: confirm whether your current accounting software includes payroll so you can avoid managing separate systems
• Prioritise ease of use: select payroll accounting software that you and your accountant can navigate without specialist training
• Choose cloud-based access: opt for online software so you can run payroll anywhere, receive automatic updates, and reduce IT maintenance, as online tools are now the most widely used method for processing wages
• Plan for growth: pick software that scales from one to over 50 employees without requiring a system change
• Verify real-time updates: use software that syncs records instantly so you stay compliant and avoid manual tracking
• Seek recommendations: ask your accountant, bookkeeper, or other business owners for suggestions, as 91% of businesses use professional services like tax agents
• Confirm reporting features: ensure the software creates all the tax forms and reports your business needs

You can also look for features such as direct credit or bank transfer management and timesheet handling.

Understanding payroll software pricing

Payroll software typically costs $20–$100 per month for small businesses, plus a per-employee fee.

Most providers use one of these pricing models:

• Per-employee pricing: a base monthly fee plus a set amount for each employee on your payroll
• Tiered plans: different feature sets at different price points, so you pay for what you need
• Bundled pricing: payroll included as part of a broader accounting or business management package

When comparing costs, consider the value payroll software provides. Automating calculations and compliance tasks can save hours of admin time each month. Many providers offer a free trial so you can test the software before committing.

Getting started with payroll software

Once you've chosen your software, getting set up is straightforward. Most small businesses complete the process in under an hour.

1. Enter your business details: add your company information and tax number
2. Add employee information: input each employee's tax forms, pay rates, and bank details
3. Set your pay schedule: choose weekly, fortnightly, or monthly pay periods
4. Run your first pay: process your first payroll and confirm everything is correct

Understanding payroll compliance requirements

Payroll compliance means meeting the legal obligations that come with paying employees. For most small businesses, this includes tax withholding, benefit contributions, and timely reporting to government agencies.

Key compliance requirements include:

• Tax withholding: deduct income tax and social contributions from employee wages, then remit payments to government agencies on schedule
• Benefit contributions: calculate and pay into social security, healthcare, and retirement schemes as required by local regulations
• Filing deadlines: submit returns and payments on time to avoid penalties and keep your cash flow predictable, keeping in mind that electronic filers must submit employment information within two working days of each payday
• Reporting obligations: provide payroll reports to tax authorities and deliver pay slips to employees according to local filing schedules
• Employee classification: include direct employees only, as contractors and freelancers invoice through their own businesses

You may have other obligations too, such as paying funds towards unemployment cover, or checking that each employee is legally allowed to work in your country.

Managing payroll changes and growth

Your payroll will change as your business grows. Good payroll software handles new employees and different payment types without extra admin.

When a new employee joins, complete all required tax documentation before their first pay. File any forms with government agencies as required by local regulations.

Your payroll may also need to handle different types of payments:

• Salaried pay: a fixed amount each pay period
• Hourly or casual pay: an hourly rate based on hours worked each week
• Commission: a percentage of the value of products or services sold
• Bonuses: additional pay for performance above agreed levels
• Supplementary wages: other payments such as overtime, severance pay, back pay, or retrospective pay increases

Record keeping and payroll archives

Payroll record keeping is a legal requirement in most countries. In the United States and the United Kingdom, you must keep records for the current tax year plus the previous three years, while New Zealand requires employers to keep full and accurate wage records for seven years.

For each employee, maintain records of:

• name, address, and any national or welfare identification number required in your country
• hire date and termination date (if applicable)
• wage and pension payment amounts and dates
• tax forms supplied to and received from the employee
• sickness or injury payment details, including dates, amounts, and payer
• tax deposit dates and amounts

FAQs on payroll software

Here are answers to common questions about payroll software for small businesses.

What's the difference between payroll software and accounting software?

Payroll software specifically handles employee payments, tax calculations, and compliance filing. Accounting software manages broader financial tasks like invoicing, expenses, and reporting. Many accounting platforms include integrated payroll features so you can manage both in one system.

Can I run payroll myself or do I need an accountant?

You can run payroll yourself with the right software. Modern payroll solutions automate calculations and filing, making it manageable for small business owners. However, many businesses still work with accountants or bookkeepers for guidance on complex tax situations or compliance requirements.

How often do I need to run payroll?

You can choose weekly, fortnightly, or monthly pay periods depending on your industry and employee agreements. Check your employment contracts and local regulations to confirm minimum payment frequencies in your region.

What happens if I make a payroll mistake?

If you make an error, correct it in the next pay run and notify affected employees. Most payroll software lets you adjust previous payments and recalculate tax obligations. For significant mistakes, consult your accountant or tax authority for guidance on how to report corrections.

Is cloud-based payroll software secure?

Reputable payroll providers use bank-level encryption and security measures to protect your data. Cloud-based systems often offer better security than storing payroll records locally, as providers maintain regular backups and security updates.
