Help to Buy has helped many first-time buyers and owner-builders top up their deposit and close a gap on the mortgage deposit. The scheme is aimed at people buying or building a brand-new home who have paid income tax in Ireland in recent years. I walk through how Help to Buy works, who can claim in 2026, how the payment is calculated, the paperwork you’ll need, typical timelines, and the common pitfalls so you can decide if it helps your mortgage offer. Read on if you’re planning to buy a new home, submit a self-build application, or if your mortgage offer depends on receiving Help to Buy funds. Bookmark it. Use it as a checklist. And check Revenue guidance for the very latest rules before you sign anything.
What Help to Buy actually is and how it works
Help to Buy refunds part of the tax you’ve already paid so first-time buyers and owner-builders can use that cash toward a deposit on a new-build home. It won’t pay out for renovations or for buying a second-hand house. Eligible buyers can claim back income tax and some deposit levies they’ve paid — turning past tax payments into a cash top-up for a new property.
The scheme only applies to newly built homes and to self-builds that meet strict 'new dwelling' criteria. That means newly constructed houses and apartments sold by a builder, or a private individual’s qualifying self-build where the property meets the scheme’s conditions. It avoids subsidising the resale market, because the policy objective is to support people getting into new housing stock and to encourage construction activity.
In practice, Revenue works out the refund from the income tax and specified levies you actually paid in the tax years the scheme allows. Revenue will pay up to a set percentage of the purchase or build cost, but there’s also a hard cash cap — you get whichever amount is lower.
The repayment comes as a tax refund from Revenue rather than a direct grant from an agency. That means the amount you can actually claim depends on two things: the tax you’ve paid and the scheme’s percentage and cap.
If you haven’t paid enough tax in the eligible years, you can only claim what you’ve actually paid — even if the scheme’s formula would allow more.
The scheme interacts with lenders and solicitors. Banks usually accept a Help to Buy award toward your deposit, but they’ll want proof the refund is approved before finalising your mortgage — and your solicitor will need the same paperwork to complete the sale. So the refund is helpful, but you must align the Revenue process with conveyancing and mortgage timetables.
Help to Buy is a targeted measure. It doesn’t replace the need for a realistic savings buffer, proof of sustainable income and the other checks banks run. Still, when it applies, it can be the difference between meeting a deposit requirement and falling short. Expect to do some paperwork and to plan the timing carefully so the money arrives when you need it.
Who qualifies in 2026: eligibility rules and common edge cases
The scheme is primarily for first-time buyers and qualifying owner-builders. You must plan to live in the property as your main home to qualify. Buy-to-let purchases and second-hand properties don’t qualify. That’s simple in theory, but real-life situations often complicate eligibility.
Joint purchasers can claim together, but both applicants must meet the relevant conditions. Married couples, civil partners and unmarried joint purchasers typically approach the claim as co-claimants. If one person is a first-time buyer and the other is not, that can affect the claim. The general principle is that the benefit attaches to the dwelling and the people who will occupy it, so both parties’ tax histories and personal circumstances can matter.
Residency and tax status play a role. You need to have paid income tax and related levies in Ireland in the tax years that the scheme allows for calculation. People who have been resident and taxed in another jurisdiction may not have the Irish tax record required to generate a refund. That doesn’t bar them from buying a home, but it may mean Help to Buy isn't available to them.
Self-builders face additional conditions. A qualifying self-build must meet the definition set out by the scheme, and you usually need completion documentation, certificates and evidence that the work carried out meets the criteria of a new dwelling.
Self-builds that are extensions or substantial renovations of an existing home often fall outside the scope. Buying a house that was built on your own land by a third party may be eligible in some cases, but the exact facts determine the outcome.
There are other tricky situations. If you inherit a property and then do work on it, that’s different from building a new dwelling from scratch. If you purchase from a family member or a related party, Revenue will scrutinise the deal. And if you previously claimed a similar tax relief or benefit tied to a property, that could affect entitlement. If you’re dealing with a shared equity scheme, social housing handover, or local authority arrangements, those can carry separate rules that interact with Help to Buy.
Always check two things early: whether the dwelling type qualifies (new build or qualifying self-build) and whether you can produce evidence of enough income tax paid in the relevant years. Those two points decide most eligibility questions.
How much you can claim and how the calculation works
Two elements determine the size of a Help to Buy claim: the scheme’s percentage of the dwelling cost and its maximum cash cap, and the total amount of income tax and specified levies you’ve actually paid in the qualifying tax years. The lesser of those figures typically sets the payment you’ll receive.
Start with the dwelling: Revenue calculates a percentage of the purchase price or the construction cost for a qualifying self-build. That percentage sets a theoretical maximum.
The scheme also sets a hard ceiling — a maximum payment that the state will allow. If the percentage of the dwelling cost exceeds that ceiling, your claim will be capped at that ceiling amount.
Next, consider your tax history. The refund can't exceed the total of income tax and relevant levies you’ve paid in the specified tax years that the scheme permits for calculation. If you haven’t paid enough tax in those years to reach the scheme’s theoretical maximum, your refund will be limited to the tax you did pay. For many purchasers this is the binding constraint: the scheme won’t create extra tax credits out of nothing.
Joint buyers bring a further wrinkle. When two people claim together, Revenue looks at the combined tax paid by both applicants in the relevant years. The combined tax must cover the joint claim. If one partner has little or no taxable record, and the other has a larger tax history, the joint claim may still succeed, but the total refund will be limited by the sum of taxes paid across both applicants.
Here are a few examples to make the arithmetic clear. Suppose the scheme allows a 10% refund and a cap of a certain amount.
If you buy a new home and 10% of the purchase price is below the cap, that 10% will be your starting point — but if you only paid a smaller amount of tax in the relevant years, your actual refund equals the tax you paid. Conversely, if 10% of the purchase price is above the cap, Revenue will cap the refund at the maximum cash limit and then compare that to your tax paid. The smaller number wins.
Self-builds can be phased. If you build in stages and incur staged certified costs, you may be able to submit a claim based on the completed element. However, each claim must meet evidence rules and the final claim can't exceed the overall scheme limits. Small variances in costs, VAT treatment and contract arrangements can change the arithmetic, so maintain careful records and seek confirmation from Revenue if you’re unsure.
Step-by-step application process and required documents
Start planning your Help to Buy claim before contracts are signed. That doesn’t mean you can get the money early, but it does mean you can gather the necessary evidence, understand timing, and ensure the mortgage and conveyancing processes accept the refund as a deposit source.
Step one: confirm eligibility. Check that the dwelling is a qualifying new build or self-build and that you intend to live there. If you’re a joint buyer, confirm both parties’ positions. Speak to your solicitor and your mortgage lender early so they know you plan to use Help to Buy as part of the deposit.
Step two: gather identity and tax documents. You’ll need personal identity details, PPS numbers, proof of address, and your tax records for the relevant years. Revenue will need to verify the income tax and levies paid in the qualifying period. If you filed tax returns, keep copies. If your tax was handled through PAYE, ensure your P60s, P45s or employer documentation are available to confirm tax paid.
Step three: assemble property and contract paperwork. That includes a signed contract for purchase or detailed self-build contracts, planning permissions, commencement notices where required, completion documentation and any architect or certifier statements that support the property’s status as a new dwelling. For self-builds, completion certs and builder invoices are especially important.
Step four: submit the claim. Claims usually go through Revenue’s online system. You’ll complete a claim form, upload supporting documents and answer questions about the purchase or build. Revenue assesses whether the dwelling qualifies and whether the tax paid meets the refund calculation. If Revenue requires further papers, respond promptly. Delays in providing evidence slow the process and can create friction with closing dates.
Step five: receive and use the refund. Revenue pays approved refunds directly. Lenders generally accept the refund as part of your deposit, but they may want written confirmation that a claim has been submitted and is approved. Ask your solicitor to coordinate payments so the funds are available at completion. If a refund arrives after closing, your solicitor can receive the funds on your behalf, but you should confirm arrangements in advance so there’s no miscommunication on completion day.
Common pitfalls, mortgage interactions and timing traps
People tend to trip up on timing. Lenders often want to know the deposit is in place at drawdown. But Revenue pays refunds after they assess the claim. That can mean the refund arrives after completion if the process began late. Plan to show the lender a credible evidence trail: proof you’ve applied, confirmation of eligibility from solicitor or adviser, and an indication from Revenue that a payment is forthcoming. Some banks accept a solicitor’s undertaking or a staged arrangement; others want the cash in the client account before releasing funds.
Another trap concerns the tax-paid requirement. Because the refund depends on tax you actually paid in relevant years, buyers who have limited earnings or who switched to low-tax employment recently may find they don’t have enough tax paid to secure the full refund. Self-employed people who didn't file returns or who had fluctuating profits must ensure their tax affairs are up to date. If Revenue finds outstanding tax liabilities, it may offset those against any refund, reducing the cash you receive.
Sure, related-party purchases attract scrutiny. Buying from family or connected parties can trigger investigations into whether the transaction was at market value and whether the property genuinely counts as a new dwelling. If you’re creating a dwelling on family land, capture clear evidence that the project meets the scheme’s definition of a new build and that payments reflect genuine costs.
Solicitors and developers sometimes misunderstand the scheme. Developers may assume that all buyers will get the refund and that it will be paid instantly at completion. That’s not how it works. Solicitors shouldn't rely on a guaranteed Help to Buy payment to complete a sale unless they have confirmation from Revenue. Buyers shouldn't assume a contract can be unconditional on receiving the refund unless their lender and solicitor accept contingency arrangements.
Finally, watch for life changes that affect eligibility. If you move abroad, change tax residency, split from a co-purchaser, or sell shortly after buying, the scheme’s terms and the tax consequences may change. If a claim is approved and then circumstances shift, get advice and notify Revenue if required. Keep records, as Revenue can audit claims years later.
Frequently asked questions and tricky scenarios
Can a couple make a joint claim? Yes, joint purchasers can claim together provided all eligibility criteria are met. Revenue assesses the combined tax paid by both applicants. If one partner lacks enough tax history, the joint claim may still proceed but the refund will be limited to the combined taxes paid.
What about buying off-plan? Off-plan purchases of new build dwellings generally qualify if the property meets the new-build criteria and you occupy the finished dwelling. Timing matters: claims are usually based on completion or the certified construction cost. Keep signed contracts and completion evidence to hand, and be aware that construction delays can push Revenue processing into a later period, which has knock-on effects for mortgage drawdown.
Does renovating an old house qualify? Plain renovations or extensions to an existing dwelling rarely qualify as a new build for Help to Buy. Substantial reconstruction that results in a brand-new dwelling might qualify if it meets the scheme’s specific definitions and documentation requirements, but these cases are assessed individually. If your project involves an existing structure, get early clarity from Revenue.
What if you paid tax abroad? Only income tax and specified levies paid in Ireland in the qualifying years typically count for a Help to Buy claim.
If most of your income tax was paid in another jurisdiction, you may not have the Irish tax record the scheme needs. That doesn’t stop you buying a home, but it may mean you can’t rely on Help to Buy funds.
Can you use the refund for part of the deposit and borrow the rest? Yes. Most buyers use the refund to top up their own savings so they meet a lender’s deposit requirement. Talk to your lender early. Some banks will accept a bank guarantee or solicitor’s undertaking alongside a claim in process, but that varies by lender and by the deal’s timing.
What if Revenue queries the claim? Respond quickly and provide the requested documentation. Many queries stem from missing certificates, unclear contractor invoices, or incomplete tax records. A prompt, organised response clears most issues. If a claim is refused, the decision letter will explain why and set out appeal rights.
