Budget 2027 calculator: what it means for you

Pay: income tax, USC and PRSI

Couples are taken as jointly assessed. Pay is treated as the same every week of the year. Pension contributions, the Additional Superannuation Contribution, Working Family Payment and the higher age-exemption limits for dependent children are not included.

What changed: the standard rate band rises by €2,500; the personal, employee and earned income credits each rise by €125; the home carer credit by €100; the 2% USC band ceiling rises by €1,600. PRSI was already set to rise: 4.2% to 4.35% on 1 October 2026 and to 4.5% on 1 October 2027, so each year's figure here is the average for the calendar year, as in the Department of Finance's own tables.

Welfare and pensions

Figures are for full-rate payments. People on a reduced rate get a proportionate increase, which is smaller. Taxable payments such as the State Pension can also change your income tax; enter other income on the Pay tab.

Maximum weekly personal rates rise by €10 from January 2027. Fuel Allowance rises by €5 to €43 a week, and the income limit for a single pensioner rises to €640.80 a week. The Living Alone Allowance rises by €3 to €25 and the Island Allowance by €5 to €25. The 2026 Christmas Bonus is paid at 100% in the week of 7 December 2026, and a new €500 Cost of Disability payment is paid in 2027. No energy credit and no double payments were announced.

Children and families

Child Benefit stays at €140 a month for each child (one and a half times that for twins, double for triplets or more). The Child Support Payment (the increase for a child on a welfare payment) rises by €6 a week, to €64 for a child under 12 and €84 for a child 12 or over. Working Family Payment income thresholds rise by €30 a week; the payment itself depends on your earnings and is not calculated here. The National Childcare Scheme universal subsidy rises from €2.14 to €2.50 an hour for children up to and including senior infants, and the weekly fee cap at services in Core Funding falls from €280 to €250 for full-time care (start dates were not stated on Budget day). From September 2027 the income-assessed subsidy's lower income threshold rises from €34,000 to €38,500. Back to School allowances are unchanged at €160 and €285.

Renting

The Rent Tax Credit rises by €150 to €1,150 for an individual and by €300 to €2,300 for a jointly assessed couple, for 2027 and 2028. The credit is 20% of the rent you pay, up to that limit, and cannot be more than the income tax you pay; it is counted in your Pay figure too. Rent a Room relief rises from €14,000 to €16,000 from 1 January 2027.

Buying a home

Help to Buy rises from €30,000 to €35,000 for purchases from 7 October 2026, the day after the Budget. It refunds income tax and DIRT paid in the previous four years, up to 10% of the price of a new or self-built home of €500,000 or less. Every buyer must be a first-time buyer, the mortgage must be at least 70% of the price, and you must live in the home; Revenue decides the claim. Stamp duty and Local Property Tax are not changed by Budget 2027. A new Derelict Property Tax of 7% of a property's self-assessed value a year will apply to properties a council lists as derelict, starting in towns of 4,000 people or more (registers from 2027). Before you bid, a free Home check sets out what public records say about a home.

Home heating: carbon tax

Carbon tax on kerosene and natural gas is cut from €63.50 to €48.50 a tonne of CO2 and held there until 2030. The Budget in Brief puts this at about €43 less on 1,000 litres of heating oil and €32 less on 11,000 kWh of gas. Carbon tax on solid fuels (coal, peat, briquettes) rises to €78.50 a tonne on 1 May 2027. The start date of the cut for oil and gas had not been published on Budget day. Your gas bill shows the kWh you used.

Car fuel and motoring

Two changes raise the price at the pump in 2027. The temporary cut in the non-carbon part of mineral oil tax, 25 cent a litre on petrol and 30 cent on diesel, is restored in steps on 28 February, 8 April and 1 May 2027, in full by 30 June 2027: about €15 more on a 60-litre fill of petrol and €18 on diesel once complete. Carbon tax on petrol and diesel rises from €71 to €78.50 a tonne on 1 May 2027 (about €1.28 more a fill of petrol, €1.48 of diesel), with a further rise on 13 October 2027. The result above is for a full year once both are in place. VRT rates for the CO2 part of the tax on Category A cars above 80g/km rise by 1 percentage point in bands 3 to 20 from 1 January 2027, and VRT relief on electric cars is extended to 31 December 2028.

Your total

The total adds your changes in pay, welfare, children's payments and heating, and takes off the extra cost of car fuel. Pay is 2027 against 2026; welfare is a full year at the January 2027 rates; heating and fuel are for a full year once each change is in place. Not included: Working Family Payment, childcare (start dates not announced), pension contributions, investment, capital gains and inheritance tax changes, and other measures that depend on circumstances this page does not ask about. Help to Buy is a one-off amount and is shown on its own tab. Rounded to the euro. This is an estimate from the published Budget measures, not tax or financial advice; Revenue and the Department of Social Protection decide your actual figures.
