What is a Tax Credit Certificate?
Your Tax Credit Certificate is the Revenue document that shows the credits, rate band and USC details used to calculate your PAYE.
What it shows
| Item | What it means |
|---|---|
| Tax credits | The credits that reduce your PAYE income tax. |
| Rate band | How much of your income is taxed at the standard rate before the higher rate applies. |
| USC rates and band | The USC rates and thresholds Revenue expects payroll to use. |
| Employment Identifier | A reference set by your employer for that employment. |

Why it matters
Your employer uses Revenue payroll instructions to calculate tax from your pay. If your credits or rate band are wrong, missing or attached to the wrong job, your PAYE may be too high or too low.
The Tax Credit Certificate is useful because it lets you check what Revenue has on record for the year.
Where to find it
Revenue says you can view, print or download your Tax Credit Certificate in the My Documents folder in myAccount. You select the relevant year folder to find it.
What your employer sees
Your employer is notified of the total credits and payroll instructions they need. Revenue says your employer is not given the full breakdown of your tax credits, only the total amount needed to calculate payroll.
