Section 2 -- Required inputs and refusal catalogue
Required inputs
Before computing any USC figure, you MUST obtain:
- Tax year -- bands change annually
- Total income -- USC is charged on gross income before pension contributions or other reliefs
- Is total income above or below EUR 13,000? -- exemption test
- Does the client hold a full medical card? -- reduced rates may apply
- Is the client aged 70 or over? -- reduced rates may apply
- Does the client have non-PAYE income exceeding EUR 100,000? -- surcharge
- Is there any DSP income? -- exempt from USC charge but counted in exemption test
If tax year is unknown, STOP. Do not compute USC.
Refusal catalogue
R-IE-USC-1 -- Cross-border USC treatment. Trigger: question about USC for non-residents or cross-border workers. Message: "Cross-border USC treatment requires specialist guidance. Escalate to qualified practitioner."
Prohibitions
- NEVER compute USC without confirming the tax year
- NEVER apply USC to income at or below the EUR 13,000 exemption threshold
- NEVER forget that the exemption test uses TOTAL income but DSP payments are exempt from the charge itself
- NEVER apply reduced rates without confirming both medical card status AND income <= EUR 60,000
- NEVER omit the 3% surcharge on non-PAYE income exceeding EUR 100,000
- NEVER conflate USC with PRSI or income tax -- three separate charges
- NEVER state that USC is deductible for income tax purposes -- it is NOT
- NEVER apply income tax credits against USC
Section 3 -- Exemption test
Legislation: TCA 1997, s 531AN
| Total income | USC liability |
|---|---|
| <= EUR 13,000 | Fully exempt |
| > EUR 13,000 | USC on ENTIRE income (not just excess) |
DSP payments are exempt from USC but are included in the income total for the exemption test.
Section 4 -- Standard bands, surcharge, and reduced rates
Self-employed surcharge
| Condition | Surcharge |
|---|---|
| Non-PAYE income > EUR 100,000 | Additional 3% on excess |
| Non-PAYE income <= EUR 100,000 | No surcharge |
Effective USC rate on non-PAYE income above EUR 100,000 = 8% + 3% = 11%.
Formula (2026)
USC = (EUR 12,012 x 0.5%)
+ ((EUR 28,700 - EUR 12,012) x 2.0%)
+ ((EUR 70,044 - EUR 28,700) x 3.0%)
+ ((min(total_income, EUR 100,000) - EUR 70,044) x 8.0%)
+ ((total_income - EUR 100,000) x 11.0%) [if non-PAYE > 100,000]
Reduced rates (medical card / aged 70+)
| Condition | Relief |
|---|---|
| Full medical card AND income <= EUR 60,000 | Max 2.0% on all income |
| Aged 70+ AND income <= EUR 60,000 | Max 2.0% on all income |
| Either condition AND income > EUR 60,000 | Standard rates on income above EUR 60,000 |
Reduced rate bands: Band 1 at 0.5% on first EUR 12,012; Band 2 at 2.0% on remainder up to EUR 60,000. Relief extended through 31 December 2027.
Section 5 -- USC and other charges interaction
| Question | Answer |
|---|---|
| Is USC deductible for income tax? | NO |
| Is USC part of PRSI? | NO -- entirely separate |
| Applied before or after tax credits? | USC on gross income; credits do not reduce USC |
| Does USC apply to DSP payments? | NO |
| Does USC apply to DIRT income? | NO -- deposit interest subject to DIRT is exempt |
Section 6 -- Payment schedule
| Payment method | Detail |
|---|---|
| PAYE employees | Deducted at source by employer |
| Self-assessed | Included in preliminary tax (31 Oct / mid-Nov ROS) and balance on Form 11 |
Section 7 -- Total marginal burden context
For self-employed individuals, USC combines with income tax and PRSI:
| Income level | Income tax | PRSI | USC | Combined |
|---|---|---|---|---|
| Below standard rate band | 20% | 4.125% | 0.5-2% | ~24-26% |
| Above EUR 70,044 | 40% | 4.125% | 8% | ~52% |
| Above EUR 100,000 (non-PAYE) | 40% | 4.125% | 11% | ~55% |
