Section 2 -- Required inputs and refusal catalogue

Required inputs

• Required inputs before computing USC — Before computing any USC figure, you MUST obtain: 1. Tax year -- bands change annually. 2. Total income -- USC is charged on gross income before pension contributions or other reliefs. 3. Is total income above or below EUR 13,000? -- exemption test. 4. Does the client hold a full medical card? -- reduced rates may apply. 5. Is the client aged 70 or over? -- reduced rates may apply. 6. Does the client have non-PAYE income exceeding EUR 100,000? -- surcharge. 7. 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

• Prohibitions list — 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

Exemption test (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 in exemption test — DSP payments are exempt from USC but are included in the income total for the exemption test. (TCA 1997, s 531AN)

Section 4 -- Standard bands, surcharge, and reduced rates

Self-employed surcharge

Self-employed surcharge

Condition	Surcharge
Non-PAYE income > EUR 100,000	Additional 3% on excess
Non-PAYE income <= EUR 100,000	No surcharge

• Effective rate on non-PAYE income above EUR 100,000 — Effective USC rate on non-PAYE income above EUR 100,000 = 8% + 3% = 11%.

Formula (2026)

• USC 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+)

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 and extension — 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.
