Budget 2027 and Your Mortgage: What Changed for Homeowners and First-Time Buyers.

The quick version

The maximum Help to Buy relief is increasing by €5,000, from €30,000 to €35,000 for qualifying first-time buyers. Renters also get additional support, with the maximum Rent Tax Credit increasing from €1,000 to €1,150 for an individual and from €2,000 to €2,300 for a jointly assessed couple.

Take-home pay also changes. The point at which a single worker starts paying the 40% rate of Income Tax will increase from €44,000 to €46,500. Personal and Employee Tax Credits will each increase by €125, while the entry threshold for the 3% USC band will rise from €28,700 to €30,300.

Those measures could give buyers more room in their household budgets. But they do not change the interest rate on your mortgage. The ECB increased its key interest rates by 0.25 percentage points in September, taking the deposit facility rate to 2.50%. For anyone whose fixed mortgage rate is ending, a change in monthly repayments could therefore absorb some or all of the additional disposable income created by Budget 2027.

That is why buyers and mortgage holders need to look at the numbers together.

Help to Buy is increasing to €35,000

One of the clearest Budget 2027 changes for first-time buyers is the increase in Help to Buy.

The maximum available through the scheme will rise by €5,000, from €30,000 to €35,000 for qualifying first-time buyers.

Help to Buy provides qualifying first-time buyers purchasing or self-building a new home with a refund based on Income Tax and DIRT paid in the relevant previous tax years, subject to the scheme’s conditions.

The additional €5,000 could make a meaningful difference to someone trying to put together a deposit. But €35,000 is the maximum, not an automatic payment to every first-time buyer. The amount you can claim depends on your qualifying tax payments and the other conditions of the scheme. Under the current Help to Buy rules, the purchase value or approved valuation of the property must also be €500,000 or less. That creates an important cliff edge for buyers.

A qualifying buyer purchasing a new home valued at €500,000 may be able to access Help to Buy, subject to their individual entitlement and the scheme conditions. A property valued above €500,000 falls outside the current property-value limit.

If you are searching close to that threshold, check your Help to Buy eligibility before building the maximum €35,000 into your property budget.

Renters get more support while saving for a deposit

Budget 2027 also increases the Rent Tax Credit. The maximum credit rises from €1,000 to €1,150 for an individual and from €2,000 to €2,300 for a jointly assessed couple. For an individual receiving the full increase, the additional €150 is equivalent to €12.50 a month across a full year. That is useful money for someone trying to build a deposit, but you need to consider it alongside the actual cost of renting.

Take a simple example. If your rent has increased by €100 per month, that is €1,200 more over a full year. An additional €150 in tax relief reduces that increase, but you are still €1,050 worse off because of the higher rent. For prospective buyers, the useful question is therefore not simply:

“How much is the Rent Tax Credit?”

It is:

“After paying my rent and other essential costs, how much can I realistically save towards my deposit each month?”

Tax changes could also help buyers’ monthly budgets

Budget 2027 includes several changes affecting workers’ take-home pay.

For a single person, the point at which Income Tax moves from the standard 20% rate to the higher 40% rate will increase by €2,500, from €44,000 to €46,500.

That means an additional €2,500 of income can potentially be taxed at 20% rather than 40%, producing a maximum Income Tax saving of €500 for someone earning enough to use the full increase. The Personal Tax Credit and Employee Tax Credit will also each increase by €125.

There is a USC change too, with the entry threshold for the 3% band increasing by €1,600, from €28,700 to €30,300. The exact benefit depends on your income and tax circumstances, so buyers should not automatically add a headline Budget figure to their mortgage affordability calculations. Instead, wait until you can see the change reflected in your own take-home pay and build your budget from there.

Mortgage rates still matter more than any single Budget saving

Budget 2027 can change your tax bill and the support available when buying a home. It does not set mortgage interest rates. On 10 September 2026, the European Central Bank increased its three key interest rates by 0.25 percentage points, with the deposit facility rate increasing to 2.50% from 16 September.

What that means for an individual mortgage depends on the mortgage itself and the lender. Tracker mortgages respond according to the ECB rate specified in the mortgage agreement. Variable rates and new fixed rates depend on individual lenders’ pricing decisions.

For borrowers approaching the end of a fixed term, the important thing is not to assume that the rate available when they originally fixed will still be available when the term expires. And this is where the Budget numbers need some context.

A worked example: Ciara and Dan’s fixed rate ends in March

Take an illustrative couple, Ciara and Dan. They have €300,000 remaining on their mortgage, with 25 years left to run, and are currently fixed at 3.0%. Their repayment is approximately €1,423 per month. If the same €300,000 balance over 25 years were charged at 3.5%, their repayment would be approximately €1,502 per month.

That is around €79 more each month, or roughly €950 more over a full year. At 3.75%, the repayment would be approximately €1,542 per month — around €119 more each month, or approximately €1,430 more over a full year.

Now put the Budget beside that. Suppose Ciara is a PAYE employee earning €55,000. Because she earns enough to benefit fully from the €2,500 increase in the standard-rate Income Tax band, that change could reduce her Income Tax by up to €500.

Assuming she can also use the €125 increases in both the Personal and Employee Tax Credits in full, those changes could reduce her Income Tax by another €250. She may also benefit from the USC change announced in Budget 2027.

The exact improvement in her take-home pay depends on her circumstances, but the comparison illustrates something important. If the household’s mortgage repayment increased by around €950 a year because their mortgage rate moved from 3.0% to 3.5%, a significant part of the Budget benefit could effectively be absorbed by the higher mortgage repayment. At 3.75%, the increase would be greater again.

That does not mean Ciara and Dan will be offered either rate. The example simply shows why a Budget saving and a mortgage-rate increase need to be considered together.

These figures are illustrative. Mortgage repayments depend on the balance, remaining term and interest rate offered by the lender, while individual tax outcomes depend on personal circumstances.

If your fixed rate ends in 2027, start with the numbers you can control

You do not need to predict where interest rates will go next to prepare for the end of a fixed mortgage rate. Start by checking the exact date your current fixed term expires.

Find out what options your existing lender may offer and compare them with alternatives available in the market when you are in a position to switch. Do not look only at the headline interest rate.

Consider the monthly repayment, remaining term, total interest cost, switching costs and any incentives offered.

Extending your mortgage term can reduce the monthly repayment but usually increases the total amount of interest paid over the life of the mortgage. Shortening the term generally has the opposite effect.

A fixed-rate expiry is therefore a useful time to ask whether both the rate and the remaining mortgage term still suit your household.

Do not forget the protection behind the mortgage

When people buy or switch mortgages, the interest rate understandably gets most of the attention. But the protection behind the mortgage matters too.

Mortgage protection is generally required when taking out a mortgage on your home, subject to limited exceptions. If you are switching lenders, you may be able to assign your existing mortgage protection policy to the new lender, subject to the lender’s requirements and acceptance of the policy.

Depending on your circumstances, arranging different cover may also be an option. The important thing is not to cancel existing cover before any replacement arrangements are fully confirmed. A mortgage switch or fixed-rate expiry can therefore be a useful opportunity to review whether both your mortgage and the protection behind it still suit your circumstances.

What should first-time buyers do after Budget 2027?

If you are planning to buy, the additional Help to Buy support should become part of your calculations, not your entire plan.

Check how much Help to Buy you may actually qualify for rather than automatically adding €35,000 to your deposit.

If you are renting, work out what the increased Rent Tax Credit means for your finances and whether you can redirect any additional disposable income toward your deposit.

Keep your mortgage approval in principle up to date. Know your realistic property budget. And start thinking about mortgage protection before you reach the final stages of the purchase.

Government support can help with the cost of buying, but it does not replace affordability checks, mortgage approval or the protection normally required before drawdown.

Your post-Budget mortgage checklist

If you already have a mortgage, check when your fixed rate ends and what your repayment could look like at different interest rates.

If you are a first-time buyer, check your potential Help to Buy entitlement based on your own tax history rather than assuming you will receive the €35,000 maximum.

If you are renting while saving for a deposit, include the increased Rent Tax Credit when planning your finances.

If the Income Tax and USC changes increase your take-home pay, decide whether some of that additional money could strengthen your deposit or emergency savings rather than simply disappearing into everyday spending.

And whether you are switching or buying for the first time, review your mortgage protection early rather than leaving it until the final stages.

Budget 2027 helps buyers. Your mortgage still needs its own plan.
