Introduction: Do Sole Traders Actually Need Payroll Software?
If you’re a sole trader who employs staff — even just one part-time member — you’re legally required to operate PAYE and report payroll information to HMRC in real time. That’s not optional. Miss it, and you’re looking at penalties.
But here’s the thing: most payroll guides are written with limited companies in mind. If you’re a sole trader, your needs are different. You probably want something simple, affordable, and ideally connected to your existing bookkeeping so you’re not duplicating work.
This guide cuts through the noise. We’ve reviewed the most popular payroll tools available in the UK and narrowed them down to the options that genuinely make sense for sole traders — covering ease of use, HMRC compliance, Making Tax Digital readiness, and value for money. By the end, you’ll know exactly which one to go for.
What Should Sole Traders Look for in Payroll Software?
Before diving into the tools themselves, it’s worth being clear on what actually matters for sole traders specifically.
HMRC Real Time Information (RTI) Compliance Every employer in the UK, including sole traders with employees, must submit payroll data to HMRC in real time through RTI submissions. Any software you use must support this — it’s non-negotiable.
Simplicity Over Features You don’t need enterprise-grade HR modules or complex org charts. You need something that calculates tax and National Insurance correctly, runs a payslip, and files to HMRC without a fuss.
Integration With Your Bookkeeping If you’re already using accounting software to manage invoices and expenses, payroll that integrates with it will save you significant time. Reconciling payroll manually across two separate systems is a headache nobody needs.
Affordable Pricing Sole traders often run on tight margins. Monthly subscriptions that cost more than your actual payroll bill don’t make business sense. Look for either free options or modestly priced add-ons.
The Best Payroll Software for Sole Traders in the UK
1. FreeAgent — Best All-in-One for Sole Traders
Price: Included free with most NatWest, Royal Bank of Scotland, Ulster Bank, and Mettle business bank accounts. Otherwise from £19/month (sole trader plan).
FreeAgent is one of the few accounting platforms built with sole traders and freelancers firmly in mind, and its payroll functionality reflects that thoughtful approach. It’s not bolted on as an afterthought — payroll sits neatly within the same interface you use for invoicing, expenses, and tax.
What FreeAgent Payroll Does Well
The payroll tool handles RTI submissions to HMRC automatically, calculates PAYE and National Insurance, and generates payslips for employees. It supports monthly and weekly pay runs, and everything feeds directly into your accounts so there’s no double-entry.
For sole traders with a handful of employees (or even just one), this streamlined approach is genuinely excellent. You don’t need a dedicated payroll administrator — the software walks you through each step clearly enough that most business owners can handle it themselves.
FreeAgent is also Making Tax Digital compliant for VAT and is actively developing further MTD capabilities, which matters as the government continues to expand the scheme.
Any Drawbacks?
FreeAgent’s payroll is relatively basic compared to standalone payroll tools. If you have complex needs — multiple pay grades, detailed absence tracking, pension auto-enrolment management beyond the basics — you may find it limiting. For most sole traders with a small number of employees, though, it hits the mark.
Best for: Sole traders who want accounting and payroll in one place, especially those banking with NatWest, RBS, Ulster Bank, or Mettle (where it’s free).
2. Xero Payroll — Best for Growing Sole Traders
Price: Payroll is included as standard from the Comprehensive plan (£50/month, up to 5 employees). It can also be added as a paid add-on on the Grow plan (£37/month). The entry-level Ignite plan (£16/month) does not include payroll.
Xero is one of the most widely used accounting platforms in the UK, and its payroll offering is genuinely polished. It’s built into the main Xero interface, so your payroll figures automatically reconcile with your accounts — no exporting, no importing, no mess.
What Xero Payroll Does Well
Xero handles RTI submissions, auto-enrolment for workplace pensions, payslip generation, and statutory payments (like Statutory Sick Pay and Statutory Maternity Pay). The dashboard gives you a clear overview of upcoming pay runs, and the system is intuitive enough to get to grips with quickly.
The pension integration is particularly strong. Xero connects with providers like NEST, which makes auto-enrolment considerably less painful — and for sole traders who’ve recently taken on staff, sorting pension compliance quickly matters.
Any Drawbacks?
Payroll is not available on the entry-level Ignite plan (£16/month). If you want payroll included in your plan rather than as an add-on, you’ll need the Comprehensive plan at £50/month — which may feel steep if your accounting needs are modest. Alternatively, adding payroll as a paid add-on to the Grow plan (£37/month) is an option worth exploring.
That said, if your business is growing and you’re already using Xero for bookkeeping, the payroll integration is one of the smoothest available.
Best for: Sole traders already on Xero who are ready to upgrade, or those anticipating growth and wanting a scalable platform.
3. QuickBooks Payroll — Best for Existing QuickBooks Users
Price: Payroll is available as an add-on to QuickBooks Online plans. Pricing starts at approximately £4/month for the Standard Payroll add-on.
QuickBooks is another UK accounting stalwart, and its payroll add-on is competitively priced for sole traders who are already subscribers. Rather than paying for an entirely new platform, you simply add payroll capability to your existing plan.
What QuickBooks Payroll Does Well
The Standard Payroll add-on covers the basics well: RTI submissions, payslip production, PAYE and NI calculations, and integration with your QuickBooks accounts. Setup is reasonably quick, and HMRC submissions happen directly from the platform.
For sole traders who are already paying for QuickBooks Simple Start (£14/month) or Essentials (£28/month), adding payroll at a relatively low monthly cost is a genuinely sensible arrangement. It keeps everything under one roof without a significant jump in outgoings.
QuickBooks also has decent customer support, including live chat, which is reassuring when you’re running payroll for the first time and inevitably have questions.
Any Drawbacks?
The Standard Payroll add-on is more basic than what you’d get from a dedicated payroll tool. More advanced features — like auto-enrolment pension management and detailed reporting — are only available on the pricier Advanced Payroll add-on. Worth bearing in mind as your team grows.
Additionally, some users find the QuickBooks interface less intuitive than FreeAgent or Xero, particularly when it comes to navigating between modules.
Best for: Sole traders already subscribed to QuickBooks Online who want to add payroll without switching platforms.
4. Sage Payroll — Best Standalone Payroll Option
Price: From £7/month (Sage Payroll Essentials, up to 3 employees).
If you’re not using an accounting platform — or if you’re using one that doesn’t offer integrated payroll — Sage Payroll is the most credible standalone option for sole traders in the UK. It’s purpose-built for payroll rather than being part of a broader accounting suite, and that focus shows.
What Sage Payroll Does Well
Sage is a trusted name with UK businesses, and its payroll software has a strong reputation for reliability and HMRC compliance. RTI submissions, payslip generation, statutory payment calculations, and auto-enrolment support are all covered.
At £7/month for up to three employees, the entry-level plan is genuinely affordable — probably the most cost-effective way to run compliant payroll if you don’t need it bundled with accounting. The interface is straightforward, and Sage provides strong UK-based support resources including guides, webinars, and a help centre.
For sole traders who perhaps do their bookkeeping in a spreadsheet or via an accountant, having a dedicated and low-cost payroll tool makes a lot of sense.
Any Drawbacks?
Because it’s a standalone payroll tool, Sage Payroll doesn’t automatically sync with your accounts in the way that integrated solutions do. If you’re using Sage Accounting separately, you can connect them — but if you’re using a different bookkeeping method, you’ll need to manage that reconciliation manually.
The interface also feels a little more traditional than newer cloud-first platforms, which some users find less polished — though many appreciate the familiarity.
Best for: Sole traders who want affordable, dedicated payroll software without committing to a full accounting platform.

FAQ
Do sole traders have to use payroll software? You’re not legally required to use dedicated payroll software, but if you have employees, you must submit PAYE information to HMRC in real time. Doing this manually is possible via HMRC’s Basic PAYE Tools (a free government option), but most sole traders find commercial payroll software considerably quicker and less error-prone. If your time has value — and it does — it’s almost always worth paying a small monthly fee.
Can a sole trader pay themselves through payroll? No. As a sole trader, you’re not an employee of your own business — you simply draw money from your business profits. You don’t pay yourself a salary or put yourself through PAYE. Payroll is only relevant if you employ other people. Your own tax and National Insurance contributions are handled through your Self Assessment tax return.
What is Making Tax Digital, and does it affect sole traders? Making Tax Digital (MTD) is the government’s initiative to move tax reporting online and in real time. MTD for VAT is already mandatory for VAT-registered businesses. MTD for Income Tax Self Assessment (MTD for ITSA) came into effect from April 2026 for sole traders and landlords with qualifying income, with further phases to follow. It’s worth choosing software that supports MTD to avoid having to switch platforms down the line.
Is HMRC’s free Basic PAYE Tools good enough for sole traders? HMRC’s Basic PAYE Tools is free and does handle RTI submissions, making it technically sufficient for very basic payroll needs. However, it doesn’t generate payslips automatically, has limited reporting, and offers no integration with your accounts. For sole traders with more than one or two employees, or those who value their time, commercial payroll software typically offers enough efficiency gains to justify the modest cost.
Conclusion: Which Payroll Software Should Sole Traders Choose?
For most sole traders in the UK, FreeAgent is the top recommendation — particularly if you bank with NatWest, RBS, Ulster Bank, or Mettle and can access it for free. It combines payroll, invoicing, expenses, and tax reporting in one intuitive package that’s genuinely built for the way sole traders work.
If you’re already using Xero, adding payroll as an add-on to the Grow plan (£37/month) or upgrading to the Comprehensive plan (£50/month) for included payroll is well worth it as your business expands. If you’re on QuickBooks, the affordable payroll add-on keeps everything in one place without much extra cost. And if you simply want a reliable, budget-friendly standalone payroll tool without committing to a full accounting platform, Sage Payroll at £7/month is hard to beat.
Whatever you choose, make sure it’s HMRC-compliant for RTI submissions and has a clear roadmap for Making Tax Digital. Get those fundamentals right, and you’ll be well ahead of the game.
