🇬🇧 UK Payroll 2026 · DIY vs Accountant vs Deel · True Cost Breakdown · PAYE + RTI + Auto-Enrolment
DIY Payroll Looks Free — But the Hidden Cost Is £3,900/Year for 8 Employees
- Time cost: 4–6 hours/month × £40/hour × 12 = £2,400/year in opportunity cost alone
- RTI penalties: 35% of UK employers miss ≥1 deadline/year — average £1,500 in annual penalties
- Auto-enrolment traps: Forgetting to enrol within 3 months = £2,000+ Pensions Regulator penalty. Full guide: UK Auto-Enrolment Guide 2026 →
- Tax code errors: Wrong code on a new starter = employer liability for underpaid tax (Rachel’s case: £3,200)
- P60 mistakes: Incorrect NI on year-end documents = mortgage application rejections, employee disputes
✅ Three Options — Quick Verdict by Employee Count
❌ DIY (HMRC Tools): Free software, but £3,900/year true cost (8 employees). Only viable for solo director paying yourself.
✅ 1–2 employees: Deel wins — £588–£1,176/year, cheaper than accountant + automated + employee portal
⚠️ 3–10 employees, hands-off: Accountant bureau wins — £1,440–1,800/year flat fee, expert oversight
✅ 5–20 employees, want control: Deel wins — employee self-service, HR features, global hiring ready
✅ Planning international hires: Deel only — EOR for Portugal, Spain, Singapore and 150+ countries
Running UK payroll yourself is legally straightforward but operationally demanding. You need to register as an employer with HMRC, calculate PAYE and National Insurance for each employee, submit Full Payment Submissions (FPS) to HMRC before every payday via Real Time Information (RTI), handle auto-enrolment into a workplace pension, and issue payslips, P45s, and P60s. The software is free (HMRC Basic PAYE Tools), but the time cost — 4–6 hours/month for 8 employees — makes it the most expensive option once your hourly rate is considered.
📊 Five Numbers That Drive the Payroll Decision

Can I Do My Own Payroll in the UK?
Yes, you can legally run your own payroll in the UK. HMRC provides free payroll software (Basic PAYE Tools) and all UK employers can submit RTI filings directly to HMRC online without an accountant or paid software. To run your own payroll, you need to register as an employer with HMRC (takes 5–10 working days), calculate PAYE income tax and National Insurance for each employee each pay period, submit an FPS (Full Payment Submission) to HMRC on or before every payday, and auto-enrol eligible employees into a workplace pension within 3 months of hiring them.
The legal framework is manageable. The practical question is whether DIY payroll is worth your time and compliance risk. For a solo director with a fixed salary, DIY costs roughly £980/year in time. For an employer with 2+ employees managing variable pay, tax code changes, leavers, and auto-enrolment deadlines, 35% of UK employers miss at least one RTI deadline per year — making the average annual penalty cost £1,500 before auto-enrolment errors are counted. See: UK PAYE Guide 2026: Set Up and Run Payroll for Small Business →
✅ When DIY Payroll Makes Sense
- Solo director only — 1 employee, fixed salary, minimal complexity
- Pre-hire stage — registered employer but no employees yet (submit EPS monthly)
- Lowest possible cash outflow — pre-seed, bootstrapped, every £ counts
- IT-literate founder — comfortable with HMRC Government Gateway and Basic PAYE Tools (Windows only)
❌ When DIY Payroll Becomes a Liability
- 2+ employees with variable pay — overtime, bonuses, commission = calculation errors
- New starters or leavers — tax code assignment (P45/starter checklist) is the #1 DIY error
- Mac or non-Windows user — HMRC Basic PAYE Tools is Windows-only; no web version
- Auto-enrolment triggered — managing NEST directly without automation adds 2+ hours/year per employee and penalty risk of £2,000+
How to Set Up PAYE for the First Time in 2026
Setting up PAYE for the first time as a UK employer requires completing five steps with HMRC before you can run your first payroll. The process takes 5–15 working days from start to first payslip — register early, as HMRC requires the registration to complete before you can submit RTI. Full step-by-step detail is in the UK PAYE Guide 2026 →
📄 5-Step PAYE Setup for New UK Employers
Register as an employer with HMRC
Go to gov.uk/register-employer. You need your business UTR (Unique Taxpayer Reference) and business address. HMRC issues your Employer PAYE Reference and Accounts Office Reference within 5–10 working days. You cannot submit RTI until this reference is issued — register before your first employee’s start date. If your first employee starts on Monday, register 3 weeks earlier.
Set up payroll software
Download HMRC Basic PAYE Tools from gov.uk/basic-paye-tools (Windows only — no Mac, no web version). Alternatively: Deel (£49/employee/month, automated RTI), Xero Payroll (£6/employee/month, RTI included), or accountant bureau (£100–150/month flat). Enter your Employer PAYE Reference and Accounts Office Reference into the software once issued.
Collect employee information and assign tax codes
For each new employee: complete a Starter Checklist (replaces P45 if employee doesn’t have one), collect NI number, confirm student loan plan, note pension status. Assign the correct tax code (1257L is the standard for most employees; use P45 tax code if available; cumulative vs week-1/month-1 matters — getting this wrong is the most common DIY error, creating employer liability for underpaid tax). Also verify right to work in the UK → before employment starts.
Set up auto-enrolment workplace pension
Every eligible employee (aged 22–66, earnings over £10,000/year) must be enrolled into a qualifying workplace pension within 3 months of their start date. NEST is the government-backed default pension provider (free to set up). You must also write to all employees within 6 weeks of their staging date explaining their pension rights. Failure to comply: £2,000+ Pensions Regulator penalty. Full guide: UK Auto-Enrolment Pension Guide 2026 →
Run your first payroll and submit FPS to HMRC
Calculate gross pay for each employee (hours × rate + any bonuses). Enter into payroll software → software calculates PAYE tax and NI deductions. Generate payslips (legal requirement — must be issued on or before payday). Submit an FPS (Full Payment Submission) to HMRC on or before payday — even one day late = £100+ penalty. Pay employees via BACS, Faster Payments, or direct bank transfer. See: UK PAYE RTI Submissions 2026: Complete Guide →
⚠️ Contractors vs Employees: Don’t Mix These Up
If you’re engaging contractors or freelancers rather than employees, PAYE may not apply — but IR35 rules determine whether a contractor should be treated as an employee for tax purposes. Getting this wrong creates significant HMRC liability. See: IR35 Guide 2026: Everything UK Contractors and Hirers Need to Know →
The Crisis Scenario: £10,000 Annual Loss from DIY Payroll
🚨 Real-World DIY Payroll Disaster — Rachel Thompson, Bristol Tech Startup, 8 Employees, £520K Revenue
Rachel runs payroll herself using HMRC Basic PAYE Tools. In 2025–26, five compounding errors cost her £10,000 — more than double what Deel would have cost (£4,704/year). Every single error was preventable with the right software. The breakdown follows.
Problem 1: Late RTI Submissions — £1,600
Rachel’s process: Friday 3pm start → 4 hours work → 7pm finish → pay Monday → submit FPS Tuesday (1 day late). Four late submissions in 2025 at escalating penalty rates.
April: £100 · June: £200 · September: £300 · November: £400 = £1,000 penalties
Three consecutive late submissions (July–Sept) triggered an HMRC audit investigation — £600 accountant fees to respond. Total RTI cost: £1,600.
Deel prevention: FPS submitted via API 5 minutes before payday — impossible to be late. See: RTI Guide 2026 →
Problem 2: Wrong Tax Code on New Starter — £3,200
Sarah joined June 2025 from a job paying £28,000. Correct code: 944T (cumulative). Rachel applied standard 1257L — underpaying Sarah’s tax by £2,400 over 6 months.
HMRC letter January 2026: “Sarah owes £2,400. Employer liable.” Rachel paid the underpayment (couldn’t recover from Sarah who had already left), then abandoned a small claims action after £800 in legal fees.
Total: £3,200. Deel prevention: auto-applies correct tax code from Starter Checklist data — system catches cumulative vs non-cumulative requirement.
Problem 3: Auto-Enrolment Missed — £2,500
Hired 2 employees July 2025, forgot to auto-enrol into NEST within 3 months. Pensions Regulator notice December: comply in 28 days or face escalating penalties.
Rachel scrambled to set up NEST (2 hours), backdated contributions. Employees furious: “You withheld £2,000 from my pay without telling me?!” Penalty: £2,000 (late compliance) + £500 (failure to issue communications).
Total: £2,500. Deel: auto-detects eligible employees (age 22+, £10K+ salary) and triggers 1-click enrolment. Full guide: UK Auto-Enrolment Pension Guide 2026 →
Problem 4: Payroll Time Waste — £2,400/Year
Monthly time breakdown (8 employees): Timesheet chasing: 1 hour | Gross pay calculation: 30 min | HMRC Tools entry: 1.5 hours | Pension deductions: 30 min | Payslip generation (Word): 1 hour | Bank payments + FPS: 1 hour
5 hrs/month × 12 × £40 = £2,400/year. Deel: 30 min/month.
Problem 5: P60 Errors — £300
Year-end P60s generated in HMRC Tools. Employee John’s NI miscalculated (Class 1 vs Class 1A confusion). His mortgage application was rejected — P60 showed wrong NI figure.
Accountant called in to correct all 8 P60s and resubmit to HMRC. Cost: £300.
Deel: P60s auto-generated from payroll data — calculation errors impossible, emailed to employees automatically by 31 May.
| DIY Payroll Error | Annual Cost | Deel Prevention |
|---|---|---|
| Late RTI submissions (4×) | £1,600 | API submits FPS before payday — impossible to be late |
| Wrong tax code on new starter | £3,200 | Auto-applies correct code from Starter Checklist; weekly HMRC sync |
| Auto-enrolment missed | £2,500 | Auto-detects eligibility, triggers enrolment, direct pension integration |
| Time waste (5 hrs/month) | £2,400 | 30 min/month — saves 54 hours/year |
| P60 calculation errors | £300 | Auto-generated from payroll data, emailed to employees by 31 May |
| Total DIY cost | £10,000/yr | Deel at £4,704/year = net saving £5,296 + 54 hours back |
TL;DR: UK Payroll Options Comparison
| Method | Monthly Cost (8 employees) | Time Required | Compliance Risk | Best For |
|---|---|---|---|---|
| DIY (HMRC Tools) | £0 software | 4–6 hours | High (£1,500/yr avg penalties) | Solo director only |
| Accountant Bureau | £100–150 flat | 30 min | Low (accountant liable) | 1–2 employees, hands-off |
| Deel UK Payroll | £392 (£49/employee) | 30 min | Very low (automated) | 3–20 employees, want control + HR |
| Method | Software/Service | Time Cost (annual) | Avg Penalties | True Annual Cost |
|---|---|---|---|---|
| DIY | £0 | £2,400 (60 hrs × £40) | £1,500 | £3,900 |
| Accountant | £1,200–1,800 | £240 (6 hrs × £40) | £0 | £1,440–2,040 |
| Deel | £4,704 | £240 (6 hrs × £40) | £0 | £4,944 |
ℹ️ The Right Question: What Are You Actually Paying For?
Accountant bureau wins on raw annual cost (£1,440–2,040 for 8 employees). But Deel‘s premium buys: employee self-service portal (payslips, P60s, bank detail updates without calling you), time-off tracking, document storage, onboarding workflows, and international hiring capability. For growing companies, the HR overhead reduction often justifies the cost differential. See full platform breakdown: Deel Review UK 2026 →
How Much Does UK Payroll Cost Per Employee?
UK payroll costs between £0 and £49 per employee per month depending on the method. HMRC Basic PAYE Tools is free but requires 10–12 minutes of manual data entry per employee per pay run. Accountant bureau pricing is typically billed as a flat monthly fee (£100–£150/month for up to 10 employees) rather than per employee, making the effective per-employee cost fall as headcount grows. Payroll software billed per employee ranges from £6/employee/month (Xero) to £49/employee/month (Deel). Add employer time cost (at £40/hour) and the true per-employee cost picture looks like this:
| Employees | DIY per employee/month | Accountant per employee/month | Xero per employee/month | Deel per employee/month |
|---|---|---|---|---|
| 1 | £82 (time + penalties) | £100 | £6 | £49 ★ |
| 3 | £68 | £40 ★ | £6 | £49 |
| 8 | £41 (true cost incl. penalties) | £19 ★ | £6 | £49 |
| 15 | Not feasible | £14 ★ | £6 | £49 |
| 20 | Not feasible | £11 (per-employee surcharges apply) | £6 | £49 |
Note that Xero Payroll at £6/employee/month is the cheapest software option at every team size — but it does not include an employee self-service portal, HR features, or international EOR. It connects to Xero accounting (a separate subscription from £16/month). For teams already using Xero, it is the logical payroll layer. See: Xero Payroll UK 2026 →
Option 1: DIY with HMRC Basic PAYE Tools — Free, But Time-Intensive
⚠️ HMRC Basic PAYE Tools: Windows Only, No Mac, No Web Version
Download from gov.uk/basic-paye-tools. Functions: calculate PAYE/NI, generate basic payslips, submit RTI (FPS/EPS). No auto-enrolment integration, no employee portal, no global hiring capability. Free software — but 5 hours/month for 8 employees makes it the most expensive option when time is valued at £40/hour.
The 5-Hour Monthly DIY Workflow
Step 1 — Collect timesheets (1 hour): Chase employees for hours, overtime, bonuses. Verify accuracy.
Step 2 — Calculate gross pay (30 min): Hours × rate + overtime for each of 8 employees. Any commission or bonus adjustments.
Step 3 — Enter into HMRC Tools (1.5 hours): Open Basic PAYE Tools → Process payroll → Enter each employee: gross pay, tax code, NI category, student loan plan, pension %. Repeat 8 times (10–12 min each).
Steps 4–6 — Payslips, payments, FPS (2 hours): Generate payslips in Word, email individually. BACS transfers or manual bank payments. Government Gateway login → submit FPS → must be before payday or £100+ penalty.
When DIY Makes Sense vs When It Doesn’t
✅ Solo director only (paying yourself £9,096 salary):
- 1 employee = ~1 hour/month
- Fixed salary = no overtime complexity
- No auto-enrolment required (1-person exemption)
- DIY annual cost: ~£980 (time + occasional penalty)
❌ 2+ employees — avoid DIY:
- Time waste: 5 hrs/month = £200/month opportunity cost
- Tax code errors: employer liability for underpaid tax
- Auto-enrolment: £2,000+ penalty if missed — see: Auto-Enrolment Guide →
- RTI deadlines: 35% of employers miss ≥1/year
- No employee self-service: constant payslip re-send requests
Option 2: Accountant Payroll Bureau — £100–150/Month
How Payroll Bureau Works
Your 30-minute monthly task: Week before payday: email timesheets + any changes (new starters, leavers, bonuses). 3 days before payday: accountant sends payslips + BACS file. Payday: upload BACS to bank, employees paid. After payday: accountant submits RTI to HMRC.
Accountant handles: All PAYE/NI calculations, payslip generation, BACS file creation, FPS/EPS RTI submissions, P45s for leavers, P60s at year-end.
Typical pricing: £100–£150/month flat (up to 10 employees) + £10–15/employee beyond 10. Year-end P60s included.
Accountant Bureau Strengths
- Hands-off — accountant handles all compliance
- Fixed, predictable monthly cost
- Expert oversight — accountant catches errors
- Existing relationship if you already have an accountant
- Cheapest option for 3–10 employees who don’t need employee self-service
Accountant Bureau Weaknesses
- 3-day turnaround — no last-minute payroll changes
- No employee self-service — employees call you for payslips, P60s
- Less control — you can’t see payroll until accountant sends it
- Not scalable — 10+ employees = per-employee fees add up
- No global hiring — accountant handles UK only
ℹ️ Accountant Bureau vs Deel: The 3-Employee Crossover Point
At 1–2 employees, accountant bureau (£100–120/month flat) is slightly more expensive than Deel (£49–98/month). At 3–10 employees, accountant bureau is cheaper in raw cost (£120–150/month vs Deel £147–490/month) — but Deel‘s employee self-service portal reduces the HR overhead that grows as headcount increases. The decision usually comes down to: do your employees need to access their own payslips and documents without going through you? For most businesses with 5+ people, the answer is yes.
Option 3: Deel UK Payroll — £49/Employee/Month

The 30-Minute Monthly Workflow
Step 1 — Review draft pay run (10 min): Deel auto-creates pay run on the 25th. Shows all employees, salaries, tax/NI. Add one-time payments (bonuses), adjust if needed (unpaid leave, salary change).
Step 2 — Approve and pay (10 min): Click “Approve” → Deel auto-generates payslips (emailed to employees), submits FPS to HMRC via API, creates BACS file (or Deel pays directly via banking partner).
Step 3 — Done (10 min post-payroll): Confirm employees received payslips via Deel portal. Answer any questions through the employee portal — no individual emails required.
Total: 30 minutes vs 5 hours DIY — saves 54 hours/year = £2,160 at £40/hr.
| Employees | Monthly Cost | Annual Cost | vs Accountant Bureau |
|---|---|---|---|
| 1 | £49 | £588 | Deel saves £612/yr vs accountant £1,200 |
| 3 | £147 | £1,764 | Accountant £1,440 = £324/yr cheaper (no employee portal) |
| 8 | £392 | £4,704 | Accountant £1,800 = £2,904/yr cheaper (but Deel scales better) |
| 15 | £735 | £8,820 | Accountant £2,520 = £6,300/yr cheaper — Deel justified by HR overhead reduction |
| 20 | £980 | £11,760 | Accountant ~£2,700 = significant gap — Deel justified by HR overhead reduction |
Compliance Comparison: What Each Option Handles
| Compliance Requirement | DIY | Accountant | Deel |
|---|---|---|---|
| FPS (on/before payday) | ⚠️ Manual | ✅ Accountant | ✅ API auto |
| EPS (nil months / SMP recovery) | ⚠️ Manual | ✅ Accountant | ✅ Auto-detects |
| Tax code updates (HMRC notices) | ❌ Email only (spam risk) | ✅ Accountant monitors | ✅ Weekly HMRC sync |
| Auto-enrolment eligibility detection | ❌ Manual (easy to miss) | ✅ Accountant tracks | ✅ Auto-detects (age 22+ / £10K+) |
| Pension contribution upload | ⚠️ Manual CSV | ✅ Accountant handles | ✅ Direct (NEST, NOW, etc.) |
| P45 (leaver — 4 working days) | ⚠️ Manual form | ✅ Accountant generates | ✅ Auto-generated, instant |
| P60 (year-end, by 31 May) | ⚠️ Manual (error-prone) | ✅ Accountant generates | ✅ Auto-generated, emailed |
| Employee self-service portal | ❌ None | ❌ None | ✅ Full portal |
| Scottish Income Tax (S prefix) | ⚠️ Manual entry | ✅ Accountant applies | ✅ Auto-applied |
| International hiring (EOR) | ❌ Not possible | ❌ UK only | ✅ 150+ countries (£599/mo) |
Payroll, Expenses and Payments: The Connected UK SME Stack
Payroll doesn’t operate in isolation. Once payroll is handled, two adjacent cost centres typically become the next priority for UK SMEs: employee expenses and business payments. These three functions connect tightly, and the software choices compound each other.
📄 Payroll (this article)
PAYE, RTI, auto-enrolment, payslips, P45/P60. Deel (£49/employee/month) or Xero Payroll (£6/employee/month).
Xero integrates payroll journals directly into accounting — no manual double-entry. See: Xero Payroll UK 2026 →
🧾 Expense Capture (Dext)
Employee expenses — receipts, mileage, subscriptions — feed into payroll for reimbursement and into Xero for accounting. Dext captures receipts via mobile app and auto-codes them. No manual keying.
See: Dext Review 2026 → and Dext + Xero + Airwallex Stack Guide →
🌍 International Payments (Airwallex)
If you’re paying contractors or remote workers internationally outside of Deel EOR, Airwallex enables multi-currency payments with real exchange rates. UK IBAN + 30 currency accounts, no FX markup on transfers.
See: Airwallex ThriveOnz360 Member Deal → and UK Expense Management Stack 2026 →
The most common UK SME stack for 5–20 employees: Deel for UK PAYE payroll + Xero for accounting + Dext for receipt capture + Airwallex for international payments. This stack eliminates manual data entry across all four functions and reduces monthly finance admin time by ~8 hours.

Cost Analysis by Employee Count — Break-Even Finder
8 Employees
Accountant Cheaper, Deel Capable
DIY: £3,900/yr (avoid — risk too high)
Accountant: £1,800/yr ★ cheapest
Deel: £4,704/yr — full HR platform
15–20 Employees
Accountant Cheapest; Deel Scales
DIY: Not feasible (8+ hrs/month)
Accountant: £2,520–2,700/yr ★ cheapest
Deel: £8,820–11,760/yr — HR overhead reduction
ℹ️ When Deel Wins Despite Higher Sticker Price
Three scenarios where Deel beats accountant bureau even at higher cost: (1) 1–2 employees — Deel is actually cheaper. (2) International hiring plans — accountant cannot handle EOR for Portugal, Spain, Singapore, or any non-UK hire. (3) 5+ employees who generate constant payslip/P60 requests — the employee self-service portal eliminates a real operational burden. See: Deel Review UK 2026 → and Deel vs Remote vs Oyster: Global Payroll EOR 2026 →
Frequently Asked Questions
Can I switch from DIY to Deel mid-year without losing payroll history?
Yes. Export your year-to-date data from HMRC Basic PAYE Tools (gross pay, tax, NI per employee for each period) and import into Deel — Deel support assists with the migration. Setup typically takes 2–3 hours with Deel’s onboarding team. Deel takes over from the next pay period, and historical data is preserved for P60 accuracy at year-end. Mid-year switches are common and fully supported.
If I already have an accountant for year-end accounts, which payroll method is best?
Keep your accountant for year-end (Corporation Tax, annual accounts, tax planning) and choose separately for monthly payroll. Two common combinations: (1) accountant bureau for payroll — simplest if your accountant already offers it; (2) Deel for payroll + accountant for year-end — gives you employee self-service and automation while retaining expert oversight on tax strategy. These are not mutually exclusive. See: Xero Review 2026 → if your accountant uses Xero as their platform.
Does Deel handle Scottish Income Tax rates automatically?
Yes. Deel auto-applies Scottish rates for employees with an S prefix tax code (e.g., S1257L). No manual configuration required — the system recognises the S prefix and uses the correct Scottish rate bands (starter, basic, intermediate, higher, top) rather than the England/Wales equivalents. Tax code updates from HMRC are synced weekly so any changes issued by HMRC are applied automatically.
Can employees access their own payslips and P60s without asking me?
With Deel: yes — employees log in to the self-service portal anytime to download payslips, P60s, and update their own bank details and contact information. With an accountant bureau or DIY: no — you must forward payslips individually, and employees will email or call asking for re-sends (a hidden time cost that grows with headcount). This is one of the most practical day-to-day advantages of Deel over the other options.
What about Construction Industry Scheme (CIS) — does Deel handle it?
Deel does not currently handle CIS (subcontractor deductions under the Construction Industry Scheme). For businesses with CIS obligations, Xero is the recommended solution — it has dedicated CIS tools built in. Accountant bureau: most handle CIS, check with your accountant first. DIY: HMRC Basic PAYE Tools supports CIS but it is complex. See: Xero Payroll UK 2026 →
What is the true cost of a late RTI submission — is it really just £100?
The first late submission in a tax year is £100. But the penalty escalates with each subsequent late submission: £200, £300, £400, capped at £500 for smaller employers. More significantly: three consecutive late submissions can trigger an HMRC compliance check — Rachel’s case resulted in £600 in accountant fees to respond to the audit, on top of the penalty itself. The full picture: 4 late submissions = £1,000 in direct penalties + £600 investigation cost = £1,600 total. See the complete breakdown: UK PAYE RTI Submissions 2026 →
How does payroll connect to the broader UK business tech stack?
Payroll sits at the centre of several connected systems: accounting software (Xero, QuickBooks) needs payroll journal entries; pension providers (NEST, NOW) need contribution uploads; HR tools need absence and headcount data. Deel integrates with Xero for accounting, major pension providers for auto-enrolment, and includes HR features (time-off, documents) natively. For expense capture, Dext connects to Xero and feeds into payroll reimbursements. For international payments, Airwallex handles multi-currency contractor payments. See: Complete SME Tech Stack Guide 2026 →
I am planning to hire someone in Portugal next year — does this change my payroll decision?
Yes — significantly. If you plan to hire internationally, Deel is the only option in this comparison that can handle it. Deel’s Employer of Record (EOR) service covers 150+ countries — they become the legal employer in Portugal (or Spain, Singapore, or wherever), handling local payroll, social contributions, employment contracts, and compliance. An accountant bureau cannot do this; DIY is impossible. Starting with Deel for UK payroll now makes the transition to international hiring seamless.

What payroll records do I need to keep in the UK?
UK employers must keep payroll records for a minimum of 3 years from the end of the tax year they relate to. Required records include: each employee’s name, NI number, tax code, and date of birth; gross pay, PAYE and NI deductions for each pay period; payslips issued; FPS and EPS submissions; P45s and P60s issued; pension contribution records for each enrolled employee; and the Starter Checklist or P45 for each new hire. With DIY or accountant bureau, you must maintain these records manually. Deel stores all records automatically in the employee portal with permanent download access — reducing admin and ensuring HMRC compliance if you’re ever asked to produce records.
Can I run payroll monthly instead of weekly in the UK?
Yes. There is no legal requirement in the UK to run payroll weekly — monthly payroll is the standard for most SMEs and is fully supported by all three methods (HMRC Basic PAYE Tools, accountant bureau, and Deel). You submit one FPS per pay period, so monthly payroll means one FPS per month to HMRC. The key requirement is that the FPS must be submitted on or before the payment date — it cannot be submitted after payday. If you pay employees on the 25th of each month, your FPS must be submitted by midnight on the 25th. Weekly payroll increases RTI filing frequency (52 FPS submissions per year vs 12) and is generally only used in industries with hourly or variable-hours workers.
