Staycationers will have to sign up to a Revenue Commissioner app and hand over their PPS number to avail of the Government's new Stay and Spend incentive.
Revenue are redesigning their RevApp to include the subsidy scheme, which will allow people claim back some of the costs of their restaurant and hotel bills.
The revamped app will allow users take a photograph of their bill which will then be uploaded into the Revenue system, where their tax refund will be calculated.
However, before availing of the subsidy, people will have to give Revenue their contact details and PPS number. The current app allows users access their Revenue account using their phones or tablet devices.
The Government is considering renaming the app as part of its relaunch next month.
Meanwhile, hotels and restaurants wanting to take part in the initiative will have to be registered with Revenue and have tax clearance certs.
Restaurants will also have to be registered with the HSE if they want their customers to be able to take part in the scheme, while Hotels will have to be registered with Fáilte Ireland.
The Stay and Spend initiative was announced as part of the Government's July Jobs Stimulus.
Couples will be able to claim back as much as €250 on hotel and restaurant bills under the Government's staycation subsidy.
The tax-back scheme is to run from October this year until April 2021 and will apply to hotels, food and non-alcoholic drinks.
Holidaymakers and diners will have to spend up to €625 to claim back the maximum €125 tax rebate. A couple can claim €250 by spending €1,250.
The incentive was developed by Finance Minister Paschal Donohoe and Tourism Minister Catherine Martin with a view to increasing spend in the hotel and restaurant sector.
The tourism sector has lost billions of euro due to the coronavirus pandemic and the restriction on international flights into the country.
The Government has urged people to book holidays at home rather than travel abroad this summer.
However, they also announced a Green List of countries where it is deemed safe to travel for non-essential reasons.
Meanwhile, employers will be paid up to €3,000 for hiring and retaining apprentices under new plans to tackle the unemployment crisis caused by Covid-19.
Higher Education Minister Simon Harris has announced details of the Apprenticeship Incentivisation Scheme which will see the Government pay businesses and employers for taking on apprentices.
Under the plan, employers who participate in the scheme are entitled to claim a €3,000 incentive payment for each new apprentice registered between March and the end of the year.
This will come in the form of an upfront payment of €2,000 to a participating employer, with a further €1,000 paid after 12 months.
"Over 18,000 people are currently undertaking an apprenticeship across a wide range of occupations from electrical, construction and engineering roles to healthcare, information technology and financial services," Mr Harris said.
