PAYE Deadline 22 May 2026: What Happens If You Pay HMRC Late?

The PAYE deadline 22 May 2026 is the first regular HMRC payment date of the new tax year for most monthly employers. If your April payroll has been submitted, the money you reported for the tax month 6 April to 5 May 2026 usually needs to clear HMRC’s account by Friday 22 May 2026 if you pay electronically, or by 19 May 2026 if you pay by post. Leave it too late and the bill can turn into a mix of daily interest, formal penalty notices, and awkward calls with HMRC just when you thought April’s payroll work was finished.

Most employers know they have to pay by the 22nd. The part that causes trouble is understanding what happens when the payment lands late, whether the first miss actually triggers a penalty, and when a Time to Pay arrangement still helps. That is where a routine monthly payroll job can get expensive.

Quick summary: for most monthly employers, PAYE for the tax month 6 April to 5 May 2026 is due by 22 May 2026 if you pay electronically. HMRC charges daily interest, currently 7.75%, on late amounts. The first late monthly payment in a tax year does not count as a default for the percentage penalty, but later late months can trigger 1% to 4% penalties, and anything still unpaid after 6 months or 12 months can attract extra 5% charges.

PAYE deadline 22 May 2026: who this applies to

For most employers paying monthly, the pattern is simple. You run payroll, send your Full Payment Submission, and then pay over the tax, National Insurance, and other payroll deductions reported for that tax month. HMRC says monthly PAYE is due by the 22nd of the next tax month if you pay electronically. The April tax month runs from 6 April to 5 May 2026, so the payment deadline is 22 May 2026.

That monthly bill is not just PAYE income tax. It can also include:

• employee Income Tax deductions
• Class 1 National Insurance
• Student Loan deductions
• CIS deductions
• Apprenticeship Levy, if it applies to your business

There is one detail worth slowing down for. The amount you pay is based on what you reported on your FPS for the previous tax month, minus any reductions you told HMRC about on an EPS submitted before 19 May 2026. So if the PAYE bill in your HMRC account looks odd, do not guess. Check the FPS, check the EPS timing, and then check the online account before you make the payment.

This deadline matters whether you have one director on payroll or a team of twenty. Small employers often assume PAYE risk is mostly about filing RTI submissions on time. Payment matters just as much. HMRC separates the two, and a clean FPS does not protect you if the money arrives late.

If you usually pay less than £1,500 a month, you may be able to pay quarterly instead of monthly, but that only applies if HMRC agrees. If you have not arranged that with HMRC already, work on the basis that the normal monthly deadline applies.

Official HMRC guidance worth keeping open:

• Pay employers’ PAYE
• Running payroll: paying HMRC
• Late payment penalties for PAYE and National Insurance

What your May 2026 PAYE bill should include

Before thinking about penalties, make sure the figure due is right. Plenty of late-payment problems start one step earlier because the payroll amount itself has not been checked properly.

For the payment due on 22 May 2026, review:

Item to check	What to confirm	Why it matters
FPS submitted for 6 April to 5 May 2026	Gross pay, PAYE, employee NIC, employer NIC, student loans	Your PAYE bill starts with the figures reported on the FPS
EPS sent before 19 May 2026	Statutory payment recovery, CIS suffered, Employment Allowance, no-payment period adjustments	Reductions need to be reflected before the bill is due
Accounts office reference	Correct payment reference used	Wrong references can make an on-time payment look late
Payment method	Faster Payments, online banking, Bacs, Direct Debit, cheque	HMRC looks at when cleared funds arrive, not when you pressed send
Cash available	Ring-fenced funds for HMRC	The money was never yours to spend in the first place

The awkward thing about May is timing. You have just come through the end of the 2025/26 tax year, April wage-rate changes, the first 2026/27 payroll, and maybe the P60 deadline on 31 May 2026 sitting just ahead. That is why the payment part can get treated as the boring final step. It is not a boring final step if the cash has already drifted into rent, stock, or supplier payments.

One useful habit is to separate the money as soon as payroll runs. If the payroll software says £4,800 is due to HMRC, move that amount into a separate tax pot or reserve account the same day. Do not leave it in the trading balance and hope nobody touches it.

If your wider payroll year-end tasks are still being tidied up, keep our PAYE year-end checklist nearby. If you are also trying to get May documents ready for staff, our P60 deadline guide is the logical next read.

What happens if you pay HMRC late

Right, so let us deal with the question most employers actually want answered. What happens if the money reaches HMRC after 22 May 2026?

There are three separate cost layers to keep in mind:

1. Daily late payment interest starts building from the due date to the date you pay.
2. Late-payment penalties for in-year PAYE can apply when you have repeated late months in the same tax year.
3. Extra 5% penalties can apply if an amount is still unpaid after 6 months and again after 12 months.

The part that surprises people is the first rule in the penalty system. For monthly and quarterly PAYE, the first failure to pay on time in the tax year does not count as a default for the percentage penalty. That does not mean it is free. Interest still runs, and if that first late amount sits there for six or twelve months, the extra 5% penalties can still hit.

HMRC is also very clear that timing is based on cleared funds, not on when you intended to pay. If you send money by a slower method and it lands after the deadline, it is late. That is why May payment problems often come from process rather than pure cash shortage.

Worked example 1: your first late PAYE payment of 2026/27

Assume your April payroll creates a PAYE bill of £4,800 due by 22 May 2026. You do not pay until 30 May 2026, and this is your first late monthly PAYE payment of the 2026/27 tax year.

What happens?

• percentage late-payment penalty for the late month: £0
• reason: the first late monthly payment in the tax year does not count as a default
• late payment interest still applies

Using HMRC’s current late payment interest rate of 7.75%, the rough interest cost for 8 days late is:

• £4,800 x 7.75% x 8 / 365 = about £8.15

That is not a huge number on its own. The real issue is behavioural. Once the first month slips, the next late month becomes much more expensive because the default protection has already been used up.

When the penalties start to bite

If another monthly payment is late later in the same tax year, HMRC can charge a percentage penalty based on how many late payments you rack up during the year.

For monthly payers, the scale is:

Number of defaults in the tax year	Penalty rate
1 to 3	1%
4 to 6	2%
7 to 9	3%
10 or more	4%

The first late month is ignored when counting defaults for this table, but after that HMRC starts charging against the amounts paid late in the relevant tax year. That means a business that is only “occasionally a few days late” can still create a year-end penalty bill if the pattern repeats.

Another point worth keeping in view is that penalties are not the only cost. Daily interest keeps running on every late amount from due date to payment date. So even a small percentage penalty can land on top of interest that has already been building.

Worked example 2: May was late, then June is late as well

Assume:

• April tax month PAYE due 22 May 2026: £4,800, paid late
• May tax month PAYE due 22 June 2026: £6,200, also paid late

Because the May payment was your first late month of the tax year, it does not count as a default for the percentage penalty. The June payment is now your first counted default.

Illustrative penalty on the June late amount:

• £6,200 x 1% = £62

If that June amount stayed unpaid for around 30 days, rough interest at 7.75% would be:

• £6,200 x 7.75% x 30 / 365 = about £39.49

So one late month after you have already used up the first-default buffer can easily cost:

• about £62 in percentage penalty
• about £39.49 in interest for a 30-day delay
• total rough cost: £101.49

That is before any accountant time, management time, or stress involved in sorting it out.

If your payroll costs have also moved up this April because of new wage rates or employer NIC changes, it is worth pairing this with our national minimum wage guide for April 2026 and new tax year checklist. Late PAYE is often a cash-flow symptom rather than a pure admin failure.

The six-month and twelve-month penalty trap

This is the part many employers miss. Even if the first late month does not count as a default for the usual percentage penalty, anything still unpaid after six months can attract an extra 5% penalty, and another 5% can apply after twelve months.

That rule applies even to the first late month in the tax year.

So if a PAYE amount due on 22 May 2026 is still unpaid around late November 2026, you are no longer talking about a small interest-only problem. By that stage, the extra 5% penalty risk is on the table. If the debt drags on for a year, it gets worse again.

Worked example 3: a PAYE balance left to drift

Assume the original late amount is £9,000 due on 22 May 2026 and it remains unpaid for about 90 days before a formal arrangement is sorted.

Rough interest for 90 days at 7.75%:

• £9,000 x 7.75% x 90 / 365 = about £171.99

If the same amount were still unpaid after six months, an extra 5% penalty could be:

• £9,000 x 5% = £450

At that point the cost is no longer a mild annoyance. It is the price of not dealing with the cash-flow gap when it first became obvious in May.

Time to Pay: when it helps and when it does not

If you know before 22 May 2026 that the business cannot pay the PAYE bill in full, do not wait for the deadline to pass and then hope HMRC will quietly let it slide. Contact HMRC as early as possible and ask about a Time to Pay arrangement.

There are two practical reasons to act early.

The first is that HMRC’s internal manual says periods covered by a Time to Pay agreement applied for before the amounts became due and payable are outside the late-payment penalty charge for those periods. The second is simpler: if you deal with the problem before the due date, you have more room to negotiate from a position of control.

That said, a payment plan is not magic. HMRC’s general guidance says payment plans are based on what you can genuinely afford, and paying more quickly means you pay less interest overall. In other words, a plan may reduce the damage, but it does not turn late tax into cheap finance.

If you cannot set up a payment plan online, HMRC says you should be ready to explain:

• how much you can repay each month
• what other taxes are due
• how much money the business earns
• what the business normally spends each month
• what savings or investments are available

That is why tidy bookkeeping matters here. If you call HMRC with vague guesses, the conversation tends to go badly. If you call with current cash-flow numbers, aged creditors, debtor timing, and a realistic proposal, you have a much stronger case.

A practical rule for May 2026

If you already know on 15 May that the business will be short on 22 May, treat that as an action date. Do not wait until 23 May to start thinking about options.

How to avoid turning May into a repeat problem

Monthly PAYE problems usually come from the same handful of causes:

• using HMRC money to cover supplier pressure
• not separating tax cash from the main bank balance
• sending payments with the wrong reference
• assuming “sent” means “received”
• missing the effect of an EPS on the final amount due
• running payroll without updating the cash-flow forecast

The fix is rarely glamorous. It is usually a better monthly routine.

Here is the process we would suggest for small employers:

1. Freeze the PAYE amount on payroll day

As soon as payroll is final, note the figure due to HMRC and move it into a separate reserve account if you can.

2. Check the EPS cut-off before 19 May 2026

If you are recovering statutory payments, claiming Employment Allowance adjustments, or reporting CIS suffered, make sure the EPS is filed in time. A late EPS can leave your online balance looking higher than expected just as the payment deadline hits.

3. Pay early enough for cleared funds

Do not treat 22 May as the day to start working out how payment systems behave. If you are using a method that takes a few working days, build that into the timetable. If you want the least drama, Faster Payments or an arranged bank transfer usually keeps things clearer than leaving a new Direct Debit setup until the last minute.

4. Match payroll and bookkeeping monthly

If payroll says one thing and the bookkeeping says another, cash-flow decisions are being made on weak information. This is where a lot of small businesses drift into late tax without meaning to.

5. Escalate the problem before the deadline, not after

If the funds are not there, act early. Waiting does not improve the numbers.

A simple May 2026 PAYE checklist

Date	Action	Why it matters
6 May 2026 onwards	Review the April payroll totals and expected PAYE bill	Gives you time to spot cash gaps early
By 19 May 2026	Submit any EPS reductions that need to affect the balance	Late EPS filing can leave the bill overstated
By 19 May 2026	Postal payment deadline if paying by cheque	Miss this and the payment will normally be late
Before Friday 22 May 2026	Make sure electronic payment will clear on time	HMRC looks at cleared funds
Before 22 May 2026 if short of cash	Speak to HMRC about Time to Pay	Early action can protect you better than late pleading
31 May 2026	Keep P60 issue in view for employees employed on 5 April	Payroll compliance does not stop with the PAYE payment

If that list feels more involved than it should, the underlying issue is often not payroll software. It is process discipline. Our bookkeeping service and payroll services are designed to work together so the payment date is backed by accurate numbers, not by hope.

FAQ: PAYE deadline 22 May 2026

What is the PAYE deadline for the April 2026 payroll month?

For most monthly employers paying electronically, PAYE for the tax month 6 April to 5 May 2026 is due by 22 May 2026. If you pay by post, HMRC says payment must usually reach them by 19 May 2026.

Does the first late PAYE payment in the tax year trigger a percentage penalty?

Usually no, for monthly and quarterly in-year PAYE. HMRC says the first failure to pay on time does not count as a default for that percentage penalty. Interest still applies, and six-month or twelve-month penalties can still apply if the amount stays unpaid for a long time.

What can be included in a PAYE bill?

A PAYE bill can include employee Income Tax deductions, Class 1 National Insurance, Student Loan deductions, CIS deductions, and Apprenticeship Levy where relevant.

Can small employers pay PAYE quarterly instead of monthly?

Sometimes. HMRC says you may be able to pay quarterly if you usually pay less than £1,500 a month, but this needs to be arranged with HMRC.

Does a Time to Pay arrangement stop every PAYE charge?

No. It can help, and HMRC’s internal guidance says late-payment penalties do not apply to periods covered by a Time to Pay agreement applied for before the amount became due. Interest can still matter, and you should not assume a late request fixes everything automatically.

What is the most useful thing to do this week?

Confirm the April payroll balance now, ring-fence the cash for HMRC, and decide before 22 May 2026 whether the business can pay in full. That one step prevents most late-payment problems.

The practical next move is simple: check what your April payroll has created, make the payment plan before the deadline crowd arrives, and speak to HMRC early if the cash is not there. If you want a second pair of eyes on the payroll numbers and the wider cash-flow picture, get in touch before the deadline rather than after it.
