These relief measures include an extension of tax filing deadlines, and reductions of the land and building tax, house transfer fee, mortgage fees, and social security contributions.

Extended tax return filing and tax payment deadlines

The extended tax return filing and tax payment deadlines would be available for certain tax returns filed electronically (that is, filed via the Revenue Department’s electronic filing (e-filing) system).

Tax payment and tax return Eligible tax month Normal deadline Extended deadline
Individual (personal) income tax  N/A 31 March 2021 30 June 2021
Withholding tax January 2021 – May 2021 15th day of the following month Last day of the following month
Value added tax (VAT) January 2021 – May 2021 23rd day of the following month Last day of the following month
Self-assessed VAT January 2021 – May 2021 15th day of the following month Last day of the following month

90% reduction of certain land and building tax

The Thai Cabinet also approved a 90% reduction of the land and building tax for assessment year 2021 for the following types of properties:

  • Land or buildings used for agricultural purposes
  • Land or buildings used for residential purposes
  • Land or buildings used for purposes other than agricultural or residential purposes
  • Undeveloped land or buildings

The reduction would apply to any owners who own the property or possess the state property for their own benefit as of 1 January 2021.

There are certain types of property that would not be subject to this relief. In addition, the Ministry of Interior has extended the deadline for land and building tax payments from the end of April 2021, to a date that is two months from the date of receiving the tax assessment—which could potentially be the end of June 2021 at the latest. 

Reduced transfer and mortgage fees for residential properties

In order to support individuals in purchasing residential properties, the transfer fee would be reduced from 2% to 0.01% and mortgage fees would be reduced from 1% to 0.01% for the sales of houses with land (i.e., a house, semi-detached house or town house) and condominiums. This fee reduction would only apply to the purchases of a house or condominium from the land developer or condominium developer if the sales price does not exceed THB 3 million (approximately U.S. $100,000).

The legislation to implement this relief measure would be effective from the date of enactment through 31 December 2021.

Reduction of social security contribution rates

Social security contribution rates would be reduced for the two-month salary cycles from February 2021 to March 2021. The reduced rates would apply to the maximum salary of THB 15,000.

  • For employees, the rate would be reduced to 0.5% (from 3%) for February and March 2021.
  • For employers, the rate would remain at 3%.
