Moving to Thailand from the UK: The Remote Worker Checklist

Form P85 or SA109, Class 3 NI at £956.80/year, UK banking, Wise setup, and the DTV application from London.

Updated September 24, 2026

Voluntary NI is now £956.80 per year (Class 2 at £182 ended April 2026). Your Barclays account will be closed once it knows you have left. HMRC needs either Form P85 or the SA109 residence pages, depending on how you report tax. Moving to Thailand from the UK has a pre-departure checklist most people discover too late.

Key Takeaways

  • ✓The DTV is your visa. Apply from London with £12,000 held across the previous 3 monthly statements and allow around 15 working days after submission
  • ✓Request an ACRO Police Certificate before assembling the application. It costs £70 and must be issued within 6 months of submission
  • ✓Use Form P85 if you do not normally file Self Assessment. Otherwise report your departure through SA109
  • ✓Voluntary NI is now Class 3 only at £956.80/year (2026/27). Decide whether it is worth it for your State Pension before you leave
  • ✓Build banking redundancy before leaving: keep traditional UK accounts and add digital accounts or card providers while your UK documents are current
  • ✓The Statutory Residence Test determines whether you remain UK resident. Your departure year may qualify for split-year treatment, while later years depend on UK days, work, homes, and ties

Visa: DTV from London

The DTV is the default visa for UK remote workers moving to Thailand. Five-year validity, 180-day stays, explicitly allows remote work, £300 fee. The London Embassy publishes a target of around 15 working days, but document requests can extend the process.

The key requirement is £12,000 in a personal savings or current account, supported by the previous 3 monthly statements. Not your Vanguard ISA, not your Coinbase wallet. Keep the balance above £12,000 throughout the statement period.

Request an ACRO Police Certificate first. It costs £70, must have been issued within 6 months of submission, and does not need to be apostilled. You must also be permanently resident in the UK, Ireland, or a British Overseas Territory and remain there until the Embassy decides the application.

For the full document checklist, processing times by embassy, and common rejection reasons, see our DTV visa guide. If you are not sure whether the DTV is right for your situation, see our visa comparison.

HMRC: what to do before you leave

File Form P85 or report through SA109

When you leave the UK, tell HMRC through the route that matches your filing position. Use Form P85 if you do not normally file Self Assessment. If you normally file Self Assessment, report your departure through the SA109 residence pages instead.

The UK personal allowance (£12,570 in 2026/27, frozen at this level until April 2031) is divided across the full year. If you leave partway through a tax year, you may have paid more tax than you owe and be due a refund, according to the Low Incomes Tax Reform Group.

How to file P85: Online via Government Gateway, or print and post. If you have a P45 from your employer, send parts 2 and 3 with the form.

Refund timing: HMRC currently issues refunds by cheque in pounds sterling. Keep your UK bank account open until you receive it.

Self Assessment

If you are self-employed or a company director, your Self Assessment obligations do not end when you leave. You must file the complete return for the tax year you depart in, including SA109. Leave in September 2026 and the 2026/27 online return is due by 31 January 2028, according to GoSimpleTax. Missing the deadline is an automatic £100 fine.

National Insurance

If you want to protect your UK State Pension while abroad, you can pay voluntary National Insurance contributions. Since April 2026, the only option for new applicants abroad is Class 3 at £18.40 per week (£956.80/year for 2026/27). Apply via form CF83.

Class 2 contributions (£3.50/week, £182/year) for periods abroad are no longer available to new applicants. If you were already paying Class 2 before April 2026, you have a transition window until April 2027 to switch to Class 3 without meeting the new eligibility criteria, according to GOV.UK.

To qualify for Class 3, you need at least 10 qualifying years on your NI record or 10 continuous years of UK residence.

Is it worth it? A voluntary year only helps if it fills a gap that increases your State Pension entitlement. Check your record and forecast at gov.uk/check-national-insurance-record before paying. Do not assume every extra Class 3 year adds the same amount to your pension.

You can pay voluntary NI contributions for gaps up to 6 years in the past. If you have gaps in your record, it may be worth filling those before paying for future years abroad.

UK tax residency: the Statutory Residence Test

Leaving the UK does not produce the same tax result for everyone. The Statutory Residence Test (SRT) looks at the complete UK tax year, from 6 April to 5 April. In the year you move, split-year treatment can separate the period before departure from the period after departure if you meet one of its qualifying cases.

The SRT has three parts applied in order:

  1. Automatic overseas test: fewer than 16 days in the UK (or fewer than 46 if not UK resident in any of the previous 3 years) = automatically non-resident.
  2. Automatic UK test: 183+ days in the UK, or your only home is in the UK = automatically UK resident.
  3. Sufficient ties test: if neither automatic test applies, residency depends on days in the UK combined with UK ties (home, family, employment).

The UK and Thailand use different tax years. The UK runs from 6 April to 5 April, while Thailand uses the calendar year. Track each separately, especially during the year you move.

The most common split-year routes for people moving to Thailand are starting full-time work overseas, accompanying a partner who does so, or ceasing to have a UK home and establishing one abroad. If you qualify, report the split through the SA109 residence pages of your Self Assessment return, according to LITRG.

Banking: which UK accounts survive

This catches people off guard. UK banks have been closing accounts of non-residents, and the policy varies by bank. The ranking from most to least reliable for remote workers moving abroad:

  1. HSBC Expat. If you qualify (£75,000 savings or £120,000 salary), it is the most reliable long-term option by a wide margin.
  2. Lloyds International. Offers international current accounts with monthly fees that can be waived when you maintain the required balance.
  3. HSBC (standard high street). Expat-aware policies without the Expat account's minimums.
  4. Monzo, Starling, Revolut. Work in practice if you keep them active, but residency is required strictly per their terms.
  5. NatWest, Barclays. Avoid or open a backup elsewhere. Account closure is either policy (Barclays) or frequent in practice (NatWest).

Barclays will close your account once they know you have moved abroad. You must live in the UK to hold a personal account, according to Barclays. If you are with Barclays, open a second account elsewhere before you leave.

HSBC is the most expat-friendly high street bank. They support customers who move abroad and offer HSBC Expat (Jersey-based, requires £75,000 in savings or £120,000 salary). If you qualify, it is the most reliable long-term option.

Lloyds International offers a Classic account with a £5 monthly fee, waived when you keep £5,000 in the account and already hold Club Lloyds. Its Plus account charges £20 per month, waived with a £10,000 balance. Treat this as a separate international account rather than assuming your existing UK current account will remain available after the move.

NatWest has no clear policy but has been known to close non-resident accounts. Not reliable.

Monzo, Starling, Revolut all require UK residency to open and, strictly per their terms, to maintain. In practice, many expats keep them running. Starling is the standout for travel: no foreign transaction fees, Mastercard exchange rate with no markup, according to Starling.

Before you leave, build redundancy while your UK address documents are current. Keep one or two established UK bank accounts and add one or two digital accounts or card providers. Keep the accounts active and do not depend on a single bank for salary, savings, card payments, or access to cash.

Moving money

The reality on a DTV: no major Thai bank opens accounts for DTV holders as of 2026 (see our banking guide). Your daily payment toolkit is Wise card + TrueMoney for QR payments + cash. Total fees: roughly £12 to 24 per month. If your visa later changes to a Non-B, Elite, or LTR, you can open a Thai bank account and that drops to near zero.

Wise is your primary tool for transfers and card spending. The fee changes with the currency, amount, funding method, and account region, so use the live quote rather than budgeting a fixed percentage. Order the physical card to your UK address before you move. Thai-address accounts opened after 21 January 2026 moved to the Thai entity progressively by August 2026; older Thai-address accounts follow from October 2026. Thai-entity accounts lose Thai ATM access and route some foreign-currency flows through THB.

Starling is the standout UK card for travel: zero foreign transaction fees, Mastercard rate with no markup, £300/day ATM limit. Good backup alongside Wise.

TrueMoney Wallet is the most reliable QR option to try without a Thai bank account. Register with your passport and Thai SIM once you land. The basic account pays supported merchant QR codes but not every personal PromptPay QR. A Thai driving licence or work permit can unlock the advanced level, although registration is not guaranteed.

For cash: bring large bills (£50 notes) and exchange at SuperRich (green logo) in Bangkok for the best rates, cheaper than any ATM withdrawal. Keep £80 to 130 equivalent in THB on you at all times.

For the full fee comparison, see our Wise vs Revolut guide.

Always send money in GBP and let Wise convert to THB. Never let your UK bank convert first. You will get a worse rate.

Pre-departure checklist

Beyond tax and banking, here are the items most UK remote workers forget:

International Driving Permit. If you plan to ride a motorbike in Thailand, you need an IDP (1968 version) from a PayPoint location. Without the correct motorcycle entitlement and an IDP valid for Thailand, assume a motorbike insurance claim will be rejected. This is the most expensive mistake on our list: documented cases exceed $9,300 out of pocket.

GP and dental. Book final appointments while you still have NHS access. Your GP can prescribe up to 3 months supply of regular medication, according to NHS guidance. After that, you source locally in Thailand.

Council tax. Notify your local council with your move-out date. You may be owed a refund for overpaid months.

Royal Mail redirection. From £45.00 for 3 months. Redirect to a UK family member's address. Apply at least 5 working days before your move at royalmail.com.

Electoral roll. Register as an overseas voter at gov.uk/register-to-vote to keep your right to vote. You now renew every 3 years; the old 15-year limit was abolished in January 2024.

Health insurance. Your GHIC or EHIC does not cover Thailand. For the first months, travel or nomad medical insurance can provide a flexible starting point if its limits, exclusions, and motorcycle rules fit your plans. If you are settling for longer, compare international or Thai health insurance for stronger inpatient cover, direct billing, and treatment of ongoing conditions. See our health insurance guide before choosing a provider.

Thai eSIM. Use a travel eSIM for data during your first few days, but check whether it includes a Thai number because many do not. Then visit an AIS or True store with your passport and visa to set up a standard prepaid or postpaid line. A stable Thai number is useful for TrueMoney, Grab, LINE, deliveries, and local services.

Next step: Request the ACRO certificate and start the 3-month £12,000 statement period first. Then confirm whether HMRC expects P85 or SA109, review your bank, and decide on voluntary NI based on your record. Leave the SIM and other arrival logistics for the final weeks.

Frequently asked questions

Do I lose NHS access when I move to Thailand?
Your GP will deregister you after 3 months abroad. Your GHIC/EHIC does not cover Thailand. You need private health insurance. When you return to the UK, you can re-register with a GP and access the NHS again.
Can I keep my UK bank account if I move abroad?
Policies vary by bank, and some providers restrict accounts after a move abroad. Set up more than one traditional account and more than one digital payment option before leaving, then keep them active. Barclays publishes restrictions for customers living abroad, so open a backup if it is your only account.
Do I need to pay National Insurance if I live in Thailand?
It is voluntary, not mandatory. If you want to protect your UK State Pension, you can pay voluntary Class 3 contributions at £956.80/year (2026/27 rate) via form CF83. Class 2 at £182/year is no longer available for new overseas applicants since April 2026. Whether it is worth it depends on your existing NI record and how long you plan to be abroad.
What is Form P85 and when do I need to file it?
Form P85 notifies HMRC that you are leaving and can help calculate a refund. Use it if you do not normally file Self Assessment. If you normally file Self Assessment, report the departure through the SA109 residence pages instead.
Will I still pay UK tax if I live in Thailand?
UK tax residency is determined by the Statutory Residence Test. Some leavers qualify for split-year treatment in their departure year, while later years depend on UK days, work, homes, and ties. Do not rely on a single 90-day rule.
