If you had a capital gain, you would not be able to offset this against an income tax credit, nor would you be able to for CAT or VAT (or offset a capital loss against DIRT etc. etc. etc). The different taxes are generally only off-settable against each other.
This is exactly the type of explanation required.
However, it seems unfair that DIRT cannot be offset against an income tax credit as contrary to taxes such as CAT, it is more likely that DIRT will affect vulnerable people such as those on low income with little or no tax liability.
Consider someone on unemployment assistance. UA does not have to be entered on a tax return. So there is no tax liability. A person on UA is permitted to have savings up to €20000 without affectig the UA payment. Yet that person must pay DIRT.
Whilst in no way begrudging the over 65s for being able to reclaim DIRT, the matter is further aggravated by allowing this vulnerable section of society to reclaim DIRT but excluding any others.
Which leads me to:
Presumably because the legislation was enacted for it to operate as it does.
Yes, it would seem so. A tax for the masses. Like one of those signs often seen 'No refunds given'.
I can't see why we should mimic how a similar tax operates in a different jurisdiction.
And I cannot see why we should not.
Germany, having a progressive tax system, recognised that similar to here with DIRT, the higher taxpayer would be at an advantage once the Abgeltungssteuer came into effect as it was a flat 25% and not as before up to a rate of 45% depending on earnings.
However, they did not penalise the lower earner or expect him to subsidise the higher earner. 25% is the maximum due - less is possible including a refund if no tax liability occurs. As the masses were affected, interest earned on deposits was counted as income and not a separate capital tax. It would have been political suicide otherwise. But here, no one bats an eyelid.
As an aside, it would do Ireland no harm on many fronts in looking to how our European partners do things. But then again we know it all, don't we? Thats why we are so far ahead here - not.
