Experts say almost every worker is entitled to claim additional credits or relief by filing their tax return.
You can go back four years when claiming tax back, and specialist Taxback.com said the average Irish tax refund its customers get is €1,880.
Many taxpayers are entitled to additional tax credits or reliefs that are not applied automatically during the year. This could include the home carer tax credit or year-of-marriage tax relief.
Workers who incur medical or certain dental expenses during the year will likely be entitled to a refund of 20pc of the cost.
The E-worker relief for those who work from home can be claimed on heating, electricity and internet bills. This can only be claimed if your employer doesn’t pay the €3.20 per day worked from home tax-free allowance to the employee.
Emergency tax is common among young workers. It occurs where a job isn’t registered with Revenue or an employee does not provide their PPS number to their employer. In such cases, the employee pays tax at a higher rate than necessary.
Some may be missing out on relief after getting married. Taxback.com said that in the year you get married, both you and your spouse will continue to be treated as single people for tax purposes.
However, if the tax you pay as two single people is greater than the tax payable if you were taxed as a married couple, you can claim the difference as a tax refund.
Taxback.com’s Joanna Murphy said Revenue’s figures show how important it is that every worker checks to see what they may be entitled to in credits and reliefs. She said refunds of €1,800 could be claimed by those overpaying their tax.
