Moving to Thailand from the UK: The Remote Worker Checklist

Voluntary NI is now £923 per year (Class 2 at £182 ended April 2026). Your Barclays account will be closed once they know you have left. HMRC needs Form P85 before you go. Moving to Thailand from the UK has a pre-departure checklist most people discover too late.

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 averages 15 working days processing but can stretch to a month, and is reported as one of the stricter embassies — they want 6 months of bank history rather than the standard 3.

The key requirement: 500,000 THB (~£11,000) in a personal savings or current account. Not your Vanguard ISA, not your Coinbase wallet. Consolidate into one account at least 3 months before applying, aim for 6 if applying through London.

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

When you leave the UK, notify HMRC by filing Form P85. This tells them you are leaving and helps calculate whether you are owed a refund for overpaid income tax.

The UK personal allowance (£12,570 in 2025/26) 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: 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 for the tax year you depart in. Leave in September 2026 and you file for the period April to September 2026 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 £17.75 per week (£923/year). 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? Each qualifying year adds approximately £6.25 per week to your State Pension. At £923 per year, it depends on how long you plan to be abroad and your existing NI record. Check your record at gov.uk/check-national-insurance-record before deciding.

UK tax residency: the Statutory Residence Test

Whether you remain UK tax resident after leaving is determined by the Statutory Residence Test (SRT), not simply by where you live. For most remote workers leaving for Thailand, the practical rule is: spend fewer than 90 days in the UK in the tax year after departure, and do not maintain a UK home, according to BDO.

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).

If you qualify, claim split year treatment through your Self Assessment return (form SA109). This means you are treated as UK resident only for the part of the year before you left. The most common cases: starting full-time work overseas (Case 1) or ceasing to have a UK home (Case 3), according to LITRG.

For what happens on the Thai side once you arrive (180-day rule, 2024 remittance change, tax rates), see our Thailand tax guide.

Banking: which UK accounts survive

This catches people off guard. UK banks have been closing accounts of non-residents, and the policy varies dramatically.

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 is relatively permissive. Multiple sources confirm they allow expats to maintain UK accounts, according to Blacktower Financial Management. They also offer an International Current Account (requires £50,000 gross annual income or £25,000 saved with Lloyds).

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.

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: salary transfers at the mid-market rate (~0.5% fee), card payments at merchants, and ATM withdrawals. Order the physical card to your UK address before you move — from May 2026, accounts registered to Thai addresses lose ATM access and auto-convert foreign currency to 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 gives you access to PromptPay QR payments (how locals pay for everything) without a Thai bank account. Register with your passport and Thai SIM once you land. Registration is inconsistent for DTV holders but worth trying.

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.

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 it, your insurance is invalid if you have an accident. 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 £41.50 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. Lasts 15 years.

Health insurance. Your GHIC/EHIC does not cover Thailand. Get private coverage before you fly. SafetyWing (£55/month) or Genki (£46/month) are the common starting points for remote workers.

Thai eSIM. Buy an eSIM directly from AIS (ais.th/esim-traveller) or TrueMove H (true.th) before you fly. This gives you a Thai +66 phone number, data, and calls the moment you land. You need the Thai number for TrueMoney, Grab, LINE, food delivery apps, and immigration reporting. Do not buy from third-party resellers (Airalo, Holafly) — those are data-only without a phone number.

Next step: Start with HMRC (P85) and your bank. These take the longest to process. Decide on voluntary NI (Class 3, £923/year) based on your NI record. Everything else can be done in the final 2 weeks before departure.
