Selling land or property? Know how much CGT you might owe.

Don’t get caught off guard by Capital Gains Tax. Use this step-by-step tool to get a clearer early estimate for land, inherited property, investment property, or a former home before you sell.

What you’ll get Your estimated CGT, likely reliefs, and key considerations

Time needed Usually less than 2 minutes

Outcome A lot more informed.

Step 1 of 7

Property type

Answer a few quick questions to get your estimate

Let’s get a quick understanding of your situation

What type of property are you selling?

Start with the closest match.

Most common House / Apartment Main residential property being sold Gifted or inherited in some cases Land Site, parcel, or non-residential land Usually taxable Investment Property Property held mainly for rental or investment May qualify for relief Former Home You lived there at one stage

Now let’s see how you got the property

How did you acquire this property?

This affects how your starting value is usually approached.

I bought it You paid a purchase price It was gifted to me You received it during the previous owner’s lifetime I inherited it You received it after a death or estate transfer

For gifted or inherited property, the relevant market value at the time you received it is often important.

2011–2014 review check
This does not change the calculator logic here, but it helps flag a period where a separate review may be worthwhile.

Purchase timing check

Did you buy this property between 7 December 2011 and 31 December 2014?

If yes, we will add a simple advisory note to your summary and PDF. This version does not build a full relief calculation for that rule.

No Continue with the standard estimate Yes Add an advisory note for separate review

Advisory only: property bought between 7 December 2011 and 31 December 2014. A separate review may be worthwhile because additional relief rules can sometimes be relevant depending on the facts.

Land-specific check
Some land sales may involve extra tax considerations. These quick questions help flag where a standard estimate may not tell the full story.

Development land check

Does this land have development potential?

For example, land with planning potential, zoning value, or development interest.

No Standard land sale Yes May have planning or development value Not sure I’m unsure whether this applies

Family farm / transfer check

Was this land part of a family farm transfer, gift, or inheritance?

This helps flag where agricultural or transfer-related review may also matter.

No No family farm or transfer context Yes Part of a family farm, gift, or inheritance Not sure I may need to double-check this

Complex case detected

Your land sale may need a more tailored review

Based on your answers, this looks like a case where a standard estimate may not fully reflect the final tax position.

Development potential can affect how land is treated.
Family farm, gift, or inheritance history can introduce separate review points.
You can still continue for an early guide, but this should not be relied on in isolation.

Next, let’s enter the main figures

A final check before we show your estimate

Gift and inheritance history

This does not change your CGT estimate directly, but it can flag when a separate gift or inheritance review may also be worthwhile.

Yes, from a parent This can matter for a separate gift or inheritance review No, not from a parent A separate review may still matter depending on who transferred it

Earlier gifts or inheritances from the same person (optional)

Enter whole thousands only if you want to flag a wider review

You entered: —

If the property was bought, we can move straight to your estimate.

Here is the outcome based on what you entered

Helpful Info

This version is focused on property, land, investment property, and former homes.

Gift and inheritance questions are there to flag when a separate review may also matter.

Enter figures in whole thousands (e.g. 250 for €250,000) to avoid errors.

Before you make a decision

A short expert review can confirm whether this estimate fully reflects your situation.

Quick questions

Does this include main home relief?

Yes. If you tell us the property was your main home at some point, the estimate includes a simple relief calculation.

Does this include the annual CGT exemption?

Yes. This version applies €1,270 per person after reliefs. For joint ownership, it models the total exemption as €1,270 × number of owners. Example: a married couple jointly owning the asset = €2,540 total exemption.

Can I use losses to reduce CGT?

Yes. Capital losses can be carried forward and used against future capital gains. They should still be reported properly so they can be referenced in later years.

When do I need to pay and file CGT?

There are two key payment periods:
• Disposals from 1 January to 30 November → pay by 15 December of that year.
• Disposals in December → pay by 31 January of the following year.

You must also report the gain in your annual tax return, even where no CGT is due because of reliefs, losses, or the annual exemption.

Are there any other reliefs this tool does not calculate?

In some cases, yes. For example, Retirement Relief may apply on certain qualifying business or farm disposals, and Revised Entrepreneur Relief may apply a reduced CGT rate on some qualifying business disposals. These are not calculated in this version.

Is this final tax advice?

No. It is an early estimate based on the figures entered and should not replace professional advice.
