Budget 2027 was announced on Tuesday 6 October 2026. For anyone who already has solar panels, the measure that touches you directly is small but real: the tax-free allowance on money you earn exporting electricity to the grid rises from €400 to €600 a year. For anyone thinking about an install, the bigger number is the €654.5 million record capital allocation behind SEAI home energy grants for 2027. And for every household in the country, the Budget cut carbon tax on kerosene and natural gas rather than raising it, and did not repeat the universal electricity credit.
- Solar export income allowance: €400 → €600 a year, per person, exempt from Income Tax, USC and PRSI
- €654.5 million record capital allocation for SEAI residential and community energy upgrades, inside €1.28 billion for the Department of Climate, Energy and the Environment
- Carbon tax on kerosene and natural gas cut to €48.50 a tonne of CO2, held there until 2030, instead of rising to €78.50
- The 14 October 2026 carbon tax rise on petrol and diesel is deferred to 1 May 2027
- Fuel Allowance up €5 to €43 a week from January 2027, and an easier means test for single pensioners
- No electricity credit. Nothing universal, for the second Budget running
- No VAT change on electricity, gas or solar panels. The €1,800 solar grant is unchanged by the Budget
The Tax-Free Allowance on Solar Export Income Goes to €600
This is the only Budget 2027 measure aimed squarely at people with panels on the roof. In the Minister for Finance's own words: "I am increasing the income tax disregard for micro-generation income received by households who sell electricity back to the grid by €200, from €400 to €600."
The Budget's tax document puts it more precisely. The exemption from Income Tax, USC and PRSI covers profits "arising from the domestic generation of electricity which is supplied to the grid", for an individual generating from renewable or sustainable sources for their own consumption. It is the section 216D relief that has been in place since 2022: €200 for 2022 and 2023, €400 from 2024, and now €600.
The Budget documents do not say. The measure sits in the Department of Finance table headed "Tax measures for introduction in 2027" and is costed at €1 million a year, but neither the speech nor the Tax Policy Changes paper gives a commencement date. Finance Bill 2026 will settle it. Until it does, treat €400 as the figure for the 2026 tax year and €600 as the figure that follows. Nothing in Budget 2027 moved the relief's end date, which Finance Act 2025 set at 31 December 2028.
Be honest about the size of this. The allowance is per person, per year, and the overwhelming majority of Irish homes never get near it. At a 20c per kWh export rate, €400 of export earnings takes 2,000 kWh of exported electricity in a year; €600 takes 3,000 kWh. A typical 4 kWp domestic array in Ireland does not export that much, because the household uses a large share of what it generates. So for most readers this change is worth precisely nothing in cash terms, because they were never going to pay tax on export income anyway.
The people it does help are a real group, though: larger arrays, homes that are empty during the day, and households on the higher export tariffs. Because the relief attaches to the individual rather than the meter, two people named on the electricity account each get their own allowance. Revenue's manual is explicit: where more than one individual is named on the electricity bill, "each individual can avail of the exemption i.e. the exemption is not split between them". So a couple's combined exempt profit moves from €800 to €1,200. If you are in that bracket, this is a genuine €200 a year each off a tax bill you were otherwise facing. Our page on Clean Export Guarantee rates sets out what the suppliers actually pay.
€654.5 Million for SEAI Grants: a Record, and Why It Matters
The larger money in Budget 2027 is on the spending side rather than the tax side. The Minister for Public Expenditure allocated €1.3 billion to the Department of Climate, Energy and the Environment for 2027, within which there is a record capital allocation of €654.5 million for SEAI residential and community energy upgrade schemes. The Department's own release puts its total at €1.28 billion and notes that €647 million of the SEAI capital figure comes from carbon tax receipts, an increase of €89 million on last year's carbon tax allocation.
That funding is also expected to be topped up from the European Regional Development Fund, which the Department says will increase the Warmer Homes Scheme allocation for 2027.
Budget 2027 did not change any grant rate. The grant changes people are actually asking about this month were approved separately on 29 September and opened on 6 October: the new €600 home battery grant, solar eligibility extending to homes built before 2025, and the €2,000 boiler scrappage payment. They are covered on our October 2026 grant changes page. What the Budget did was put the money behind them for a full year.
On a scheme where processing time has been the binding constraint rather than grant generosity, a bigger allocation is the more useful of the two. The Minister's stated expectation is blunt enough: the funding "will encourage even more home solar PV installations".
Carbon Tax Was Cut, Not Raised, and the October Rise Is Gone
This is the reversal in the Budget, and if you have read anything on this site about carbon tax in the last year it changes the picture. Carbon tax on home heating fuels was sitting at €63.50 per tonne of CO2 and scheduled to climb to €78.50 by 1 May 2027. Instead:
| Fuel | Was scheduled | Budget 2027 decision |
|---|---|---|
| Kerosene (home heating oil) | Rise to €78.50/t by 1 May 2027 | Cut to €48.50/t, held until 2030 |
| Natural gas | Rise to €78.50/t by 1 May 2027 | Cut to €48.50/t, held until 2030 |
| Petrol and diesel | Rise to €78.50/t on 14 October 2026 | Deferred to 1 May 2027, then back on the path to €100/t from 13 October 2027 |
| Solid fuels and minor fuels | Staged increases | Double increase on 1 May 2027, €63.50/t to €78.50/t |
| Marked gas oil (MGO) | Increase on 1 May 2027 | Deferred to 13 October 2027 |

The Minister described the kerosene and gas reduction as being "maintained for the lifetime of the government", and added that the decision not to proceed with future increases on those products "will ultimately result in the carbon tax rate being less than half of what was set out originally". Separately, the temporary excise cuts on petrol and diesel were extended in full to 28 February 2027, with restoration then phased over four steps and completed on 30 June 2027.
What does that do to the case for going solar? Less than it might look like. Carbon tax is a tax on burning fossil fuel, so cutting it makes oil and gas heating cheaper relative to a heat pump. That is a genuine dent in the switching argument for heating. It does nothing to the economics of solar panels, because solar competes with the electricity price, and the Budget left the electricity price untouched. Our carbon tax page has the detail on what the tax adds to a fill of oil.
There Is No Electricity Credit in Budget 2027
For the second Budget in a row, there is no universal electricity credit. It does not appear in the Minister for Finance's statement, in the Social Protection package, or in the Department of Climate, Energy and the Environment's own list of household energy measures. The €450-per-household era of 2022 and 2023 is over, and the Government has settled on targeted payments instead:
- Fuel Allowance up €5 to €43 a week from January 2027, worth over €1,200 across the year to some 460,000 recipients
- An easier Fuel Allowance means test for single pensioners. From January 2027 the income limit for a single person aged 66 or over rises from half a couple's limit to 60% of it, which brings more older people into the payment
- Living Alone Allowance increased for the first time in five years for pensioners and disabled people living alone
- A first-ever Cost of Disability payment, starting as a €500 lump sum in 2027
If you were waiting on a credit to get through the winter, that is the answer: there isn't one, and the supports that exist are means-tested. Our energy credit page tracks where this has landed. It is also the argument for the Warmer Homes Scheme, which is fully funded rather than part-funded and now includes solar PV as standard for eligible households.
What Budget 2027 Did Not Change
Three things people expected to move did not, and in each case the absence is the useful fact:
- 0% VAT on solar panels stays. The supply and installation of solar panels on a private dwelling has been zero-rated since 1 May 2023. There is no solar VAT measure anywhere in the Budget 2027 tax package. The only VAT changes are to livestock vaccines, the farmer's flat-rate payment and the charity compensation scheme. See how 0% VAT stacks with the grant.
- 9% VAT on electricity and gas stays. Budget 2026 already extended the reduced rate to 31 December 2030, and Budget 2027 left it alone.
- The €1,800 solar grant is unchanged. Still €700 per kWp to 2 kWp, then €200 per kWp to 4 kWp. See the SEAI Solar Electricity Grant page.
One more measure worth flagging for anyone charging a car off their own roof: VRT relief on electric vehicles was extended by two years to 31 December 2028, and VRT rates on more polluting cars in bands 3 to 20 rise by 1% from 1 January 2027. If solar plus an EV is the plan, see charging an EV with solar.
The grant is €1,800, VAT on the install is 0%, and the first €600 a year you earn exporting is heading tax-free. The only number left is what an installer charges for your roof.

Budget 2027 is the second Budget shaped by the National Energy Affordability Taskforce, and the shape is now clear: no universal cash, structural money instead. The Minister for Finance framed the carbon tax decision around two energy price shocks in five years and a Middle East conflict pushing oil prices up since February, and committed to no increase "in any form of tax either at the pump or in your home during this winter period".
Alongside that sits €1.5 billion already injected into the ESB and €2 billion to be invested by EirGrid to strengthen the grid for renewables, plus a further National Energy Affordability Taskforce report due shortly. An Energy Affordability Action Plan is expected to follow the Budget. So the measures above are not necessarily the last word of the year on energy costs. They are, though, the ones that have been voted on.
Frequently Asked Questions
No. Budget 2027, announced on 6 October 2026, contained no universal electricity credit. It does not appear in the Minister for Finance's Budget statement, the Department of Social Protection package or the Department of Climate, Energy and the Environment's list of household energy measures. The household energy supports in this Budget are targeted instead: the Fuel Allowance rises by €5 to €43 a week from January 2027, the Living Alone Allowance increases, and a new Cost of Disability payment starts with a €500 lump sum in 2027.
€600 a year per person, up from €400. Budget 2027 increased the microgeneration income disregard by €200, and it continues to cover Income Tax, USC and PRSI on profits from domestic electricity supplied to the grid. The Budget documents do not state a commencement date, so €400 remains the figure for the 2026 tax year and Finance Bill 2026 will confirm when €600 applies. Because the relief is per individual and, in Revenue's words, is not split between people named on the same electricity bill, two named account holders have a combined exempt profit of €1,200.
No. The maximum domestic solar PV grant is unchanged at €1,800: €700 per kWp up to 2 kWp, then €200 per kWp up to 4 kWp. Budget 2027 funded the schemes rather than changing their rates, with a record €654.5 million capital allocation for SEAI residential and community energy upgrades in 2027. The grant changes that did happen, including the new €600 home battery grant and eligibility extending to homes built before 2025, were approved separately on 29 September 2026 and opened on 6 October 2026.
No. Carbon tax on kerosene and natural gas has been reduced to €48.50 per tonne of CO2 and will be held at that rate until 2030, instead of rising to €78.50 per tonne by 1 May 2027. The Minister for Finance said the rates would be maintained for the lifetime of the government. Separately, the carbon tax increase on petrol and diesel that was due on 14 October 2026 is deferred to 1 May 2027, with those fuels returning to the Finance Act 2020 path toward €100 per tonne from 13 October 2027.
No. The supply and installation of solar panels on a private dwelling remains zero-rated for VAT, as it has been since 1 May 2023. There is no solar VAT measure in the Budget 2027 tax package; the only VAT changes are a 9% rate on non-oral respiratory vaccines for livestock, a rise in the farmer's flat-rate payment to 4.8%, and an increase in the VAT Charity Compensation Scheme fund to €15 million. The 9% VAT rate on electricity and gas also stays, having already been extended to 31 December 2030 in Budget 2026.
€43 a week from January 2027, up €5, which the Department of Social Protection says is worth over €1,200 across the year to some 460,000 recipients. The means test also loosens for single pensioners: from January 2027 the income limit for a single person aged 66 or over rises from half a couple's limit to 60% of it, so more older people qualify.
Marginally better, and mostly unchanged. The export income allowance rising from €400 to €600 helps the minority of households that export enough to be taxed on it. The record €654.5 million SEAI allocation makes a long grant queue more likely to move than a short one. Nothing in the Budget touched the €1,800 grant, the 0% VAT on installation, or the 9% VAT on the electricity that solar displaces. The carbon tax cut on kerosene and gas slightly weakens the case for switching heating to a heat pump, but it does not affect solar panels, which compete against the electricity price rather than the price of oil.
