The Revenue Commissioners has said homeowners will begin to receive personalised assessment letters outlining details of the property tax from next week.

It will take up to four weeks for the letters to be delivered to 1.6 million houses.

From Sunday, an interactive guide for house values will go online in order to help homeowners decide what value bracket their home falls into.

A local property tax return will be included with the letter and homeowners will be able to choose a number of methods to pay the tax.

If homeowners do not respond to the Revenue estimate, they will be pursued for the monies.

Revenue Chairperson Josephine Feehily has said it is inevitable that some letters may be sent in error.

She said that some letters may be sent to people who have died, while others may be sent in error to tenants instead of landlords.

It will be up to current property owners to pay the tax despite the errors.

Ms Feehily also said that those who have not paid the Household Charge will still be liable for it.

She said if people have not paid the charge by 1 July that it gets converted into an amount of local property tax of €200.

Elsewhere, Tánaiste Eamon Gilmore has defended the introduction of the property tax, insisting that householders will be able to engage with Revenue if they feel the estimate of the value of their property is wrong.

Mr Gilmore was responding to questions from Sinn Féin's Mary Lou McDonald in the Dáil.

Ms McDonald said the Government was planning to put its hand into the pockets of people who were struggling, with a tax that took no account of individual circumstances.
