Thailand has announced tax relief for people whose homes and vehicles have been damaged by flooding in 2026. The measures include deductions for qualifying repair costs and extensions for certain tax filing and payment deadlines.
Status at 22 October 2026: Cabinet has approved the repair deductions. We have not yet found the legislation or the detailed Revenue Department rules needed to claim them. The amounts and conditions below reflect the announcement. Eligibility and claiming requirements still need confirmation.
For expats, the questions are whether you qualify, which costs are covered and how much a deduction could reduce your Thai tax bill. The announced property measure includes tenants as well as owners.
What Tax Relief has been Announced
The Ministry of Finance announcement of 20 October 2026 sets out two categories of personal income tax relief:
| Expense | Maximum Deduction | Claimants | Costs Covered |
| Home or condominium | THB100,000 | Owner, tenant or other user | Repairs, cleaning and materials for the building, unit and fixed structures or fittings |
| Car or motorcycle | THB30,000 | Owner or hire purchase buyer | Repairs and related materials, including vehicle equipment |
The flood damage must occur between 15 May and 31 December 2026, and qualifying costs must be paid within the same period. The damaged property must be in an officially declared disaster area or emergency disaster assistance area.
Each limit applies to the combined costs in that category, even if several properties or vehicles were damaged.
Can Expats and Tenants Claim Flood Relief
The announced relief is for individual taxpayers. It excludes ordinary partnerships and groups that do not have separate legal status. The announcement does not state a Thai nationality restriction. Foreign taxpayers may therefore qualify, subject to the final rules.
Tenants are expressly included in the property measure. Keep your tenancy agreement, repair bills and proof that you paid them.
Check your position if the property belongs to your spouse, the landlord arranged the work or the receipts are in someone else’s name. Who was responsible for the cost and who paid it may affect the claim.
Keep a separate record of insurance payments and other reimbursements. These may affect how much of your repair bill you can claim.
How Much Tax could you Save
A deduction reduces the income on which your tax is calculated. It does not reimburse the full cost of the repairs.
For example, suppose your taxable income before this relief is THB950,000. A qualifying THB100,000 deduction would reduce it to THB850,000.
Under the Revenue Department’s income tax rates, all of that THB100,000 reduction falls within the 20% band. The tax saving would therefore be THB20,000, before tax credits or other adjustments.
Your actual saving depends on your income and the rest of your tax calculation. It may be smaller if part of the deduction falls in a lower tax band or tax credits already reduce the amount you owe. The deduction alone does not create a cash payment if you have no tax liability.
What Tax Filing Extensions have been Announced
The announced extension would move qualifying filing and payment deadlines falling between 1 September and 29 December 2026 to 30 December 2026.
The announcement covers paper and online filing in locations specified by the Revenue Department. Taxes listed include personal and corporate income tax, withholding tax, VAT and specific business tax. It also covers applications to pay stamp duty in cash. The specific business tax extension excludes property sales made commercially or for profit.
This does not give everyone in a flood-affected province an automatic extension. Check that your location, the tax involved and the original deadline are covered before delaying a return or payment.
The Ministry also says the Revenue Department is preparing a further extension for floods that occurred before 1 September 2026. If you were affected in May to August, check that separate announcement when it is published.
The announcement does not extend the deadline for the 2026 annual personal income tax return due in 2027. Check the relevant Revenue Department notification before relying on a new deadline.
What Evidence should you Keep
Start collecting your records now. Useful evidence includes:
- Dated photos of the flood damage and repairs
- The disaster declaration covering the property’s address and the dates of the flooding
- Ownership, tenancy or hire purchase documents
- Itemised invoices and receipts showing the work, supplier and cost
- Bank statements or other proof of who paid and when
- Records of insurance payments, reimbursements and government assistance
Keep repairs, cleaning, materials and replacement purchases clearly separated in your records. A quote or estimate is not proof of payment.
Receipt formats and any requirement for electronic receipts still need confirmation in the final claiming rules. Keep clear invoices, receipts and proof of payment now, then check the published requirements before claiming.
How do Insurance and Other Assistance Differ
The wider flood response also includes insurance, housing repair aid, cash assistance and bank support. Each has its own eligibility and payment rules.
The government’s national disaster insurance programme runs from 1 October 2026 to 1 October 2027. Home cover is up to THB100,000 per event, per household, subject to the policy terms. For eligible flood claims, this is an initial THB10,000 payment plus up to THB90,000 for actual damage.
Thai PBS reported that Thailand’s insurance regulator, the Office of Insurance Commission (OIC), said the registered householder must be a Thai national. Cover applies to the building and fixed fittings. It excludes electrical appliances and freestanding furniture.
Claims require ThaiD identity checks. Government guidance lists payment through PromptPay linked to a Thai ID number or by bank transfer. Thai PBS says the PromptPay account must be in the registered householder’s name. Foreign owners and tenants should check the scheme’s eligibility and payment requirements before relying on cover.
Under the reported policy terms, flooding that began before cover started may be excluded, even if it continues to cause damage afterwards.
A separate government assistance scheme offers up to THB88,600 per home towards repairs, subject to eligibility and assessment of the damage. Applications are made in person through the local authority or a Bangkok district office.
A separate cash assistance scheme covers qualifying flooding between 15 May and 30 September 2026. Announced payments are THB9,000 or THB5,000 per household, depending on the circumstances. Check its rules separately from the tax measure.
The Finance Ministry’s bank assistance measures include debt relief and recovery loans. Contact the relevant bank to check whether you qualify and what terms apply.
Is Flood Compensation Taxable
Existing Revenue Department rules exempt qualifying government disaster compensation and certain other assistance from income tax.
For government compensation, one condition is registration with an official relief agency. For certain other qualifying assistance, the exemption is limited to the actual loss.
Keep the award letter or claim decision and proof of payment so the tax treatment can be checked. The rules for exempt compensation and deductions for repair costs are separate.
