Section 2 -- Required inputs and refusal catalogue

Required inputs

• Required inputs before computing Medicare levy — Before computing any Medicare levy figure, you MUST know: 1. Residency status for tax purposes -- Australian resident, foreign resident, or temporary resident; 2. Taxable income for the year -- Medicare levy is calculated on taxable income; 3. Marital/family status -- single, married/de facto, with or without dependent children; 4. Number of dependent children -- affects family threshold; 5. Spouse's taxable income -- affects family threshold eligibility and MLS; 6. Private health insurance status -- does the client (and family) hold appropriate private patient hospital cover for the full year?; 7. Any days of exemption? -- foreign resident days, specific medical condition categories; 8. Entitlement to SAPTO? -- seniors and pensioners get higher Medicare levy reduction thresholds

Refusal catalogue

• R-AU-ML-1 — Diplomatic or prescribed overseas forces exemption. Trigger: client claims exemption on diplomatic or overseas forces grounds. Message: "Diplomatic and prescribed overseas forces Medicare levy exemptions require verification of eligibility that is outside this skill's scope. Please escalate to a qualified tax agent."
• R-AU-ML-2 — Norfolk Island transitional provisions. Trigger: client is a Norfolk Island resident claiming transitional provisions. Message: "Norfolk Island transitional Medicare levy provisions are outside this skill's scope. Please escalate to a qualified tax agent."
• R-AU-ML-3 — Complex partial-year residency with multiple visa changes. Trigger: client has more than two residency status changes during the income year. Message: "Multiple residency status changes during the year require detailed analysis of each period. Please escalate to a qualified tax agent for pro-rata computation."

Section 4 -- Levy computation rules

4.1 Standard Medicare Levy (Tier 1)

• Standard Medicare levy formula — Medicare levy = taxable income x 2% (Medicare Levy Act 1986 s 6)
• Basis of calculation — The Medicare levy is calculated on taxable income (not gross income, not adjusted taxable income). It is applied automatically by the ATO when the tax return is assessed. (Medicare Levy Act 1986 s 6)

4.2 Low-income reduction -- singles (Tier 1)

• Low-income reduction formula for singles — If taxable_income <= $27,222: Medicare levy = $0. If $27,222 < taxable_income <= $34,027: Medicare levy = (taxable_income - $27,222) x 10%. If taxable_income > $34,027: Medicare levy = taxable_income x 2%. (Medicare Levy Act 1986 s 7)
• Shade-in rate explanation — The shade-in rate of 10% means the levy increases by 10 cents for every dollar earned above the lower threshold, until the reduced levy equals the standard 2% levy (which occurs at the upper threshold). (Medicare Levy Act 1986 s 7)
• SAPTO substitution for singles — For SAPTO-entitled singles: substitute $43,020 for $27,222, and $53,775 for $34,027. (Medicare Levy Act 1986 s 7)

4.3 Low-income reduction -- families (Tier 1)

• Family threshold formula — Family threshold = $45,907 + ($4,216 x number_of_dependent_children) (Medicare Levy Act 1986 s 8)
• SAPTO family threshold formula — For SAPTO-entitled families: Family threshold = $63,486 + ($4,216 x number_of_dependent_children) (Medicare Levy Act 1986 s 8)
• Family threshold effect — Family income at or below the family threshold: no Medicare levy payable for either spouse. Family income above the family threshold: each spouse pays their individual share, subject to individual reduction rules. (Medicare Levy Act 1986 s 8)
• Family income for Medicare levy purposes — Family income for Medicare levy purposes = combined taxable income of both spouses + any exempt foreign employment income + any net financial investment loss + reportable super contributions. (Medicare Levy Act 1986 s 8)

4.4 Medicare Levy Surcharge (Tier 1)

• MLS overview — The MLS is a separate levy on top of the standard 2% Medicare levy. It applies to taxpayers who do NOT hold appropriate private patient hospital cover and whose income exceeds the MLS threshold. (ITAA 1997 s 8C-8G)
• Income for MLS purposes — Income for MLS purposes = taxable income + reportable fringe benefits total + total net investment loss (including net financial investment loss and net rental property loss) + super lump sum (taxed element, untaxed element) - child support paid. (ITAA 1997 s 8C-8G)
• MLS pro-ration and appropriate cover definition — MLS is pro-rated for each day the client (and/or dependants) do not have appropriate private hospital cover. Appropriate cover means private patient hospital cover with an excess of no more than $750 for singles or $1,500 for families/couples. (ITAA 1997 s 8C-8G)
• Family threshold applies regardless of spouse income — If married/de facto, the family threshold applies regardless of whether the spouse earns income. (ITAA 1997 s 8C-8G)

4.5 PHI rebate interaction (Tier 1)

• PHI rebate vs MLS purposes — The PHI rebate and the MLS use the same income tiers but serve opposite purposes. PHI rebate is a government subsidy for holding private health insurance (reduces with higher income). MLS is a penalty for NOT holding private health insurance (increases with higher income). (Private Health Insurance Act 2007 Part 2-2; ITAA 1997 Div 61)

Planning note: For clients in Tier 1 or Tier 2 MLS, holding private hospital cover eliminates the MLS AND provides the PHI rebate. The cost of private cover is often less than the MLS, making it financially beneficial.

Section 5 -- Exemptions and special categories

5.1 Full exemption categories (Tier 1)

Full exemption categories table

Category	Exemption
Foreign residents (for the full year)	Full exemption from Medicare levy for the entire year
Temporary residents not eligible for Medicare	Full exemption (must hold valid visa and not be enrolled in Medicare)

5.2 Half or partial exemption categories (Tier 2)

Half or partial exemption categories table

Category	Exemption
Part-year residents	Pro-rata exemption for non-resident days. Flag for reviewer.
Specific medical conditions (Category 1)	Blind persons -- full exemption. Complete Medicare Levy Exemption Statement.
Specific medical conditions (Category 2)	Persons in specified care -- partial or full exemption depending on circumstances. Flag for reviewer.

5.3 Reciprocal Health Care Agreements (Tier 2)

• Reciprocal health care agreements — Australia has reciprocal health care agreements with several countries (UK, Ireland, New Zealand, Sweden, Netherlands, Belgium, Finland, Italy, Norway, Slovenia, Malta). Residents of these countries visiting Australia may be entitled to Medicare and therefore NOT exempt from the levy. Flag for reviewer to confirm coverage.
• Non-reciprocal foreign residents exemption and M1 — Foreign residents who are NOT covered by a reciprocal agreement and NOT enrolled in Medicare are exempt from the Medicare levy. They must complete item M1 on the tax return.

Section 6 -- Completing the tax return

6.1 Item M1 -- Medicare levy reduction or exemption

• When to complete M1 — Complete M1 if: taxable income is within the low-income shade-in range; you are claiming a full or half exemption; you had a spouse during the year.

6.2 Item M2 -- Medicare levy surcharge

• When to complete M2 — Complete M2 if: you (or your spouse/dependants) did not have appropriate private hospital cover for any day during the year; your income for MLS purposes exceeds the relevant threshold ($97,000 singles / $194,000 families). If the client held appropriate cover for the full year, M2 does not need to be completed (no MLS is payable).

Section 7 -- Edge case registry

EC1 -- Part-year resident (Tier 2)

Situation: Client was a foreign resident for 3 months then became an Australian resident for the remaining 9 months. Resolution: Medicare levy is calculated on the full year's taxable income, but a pro-rata exemption applies for the non-resident period. The exemption is calculated as: (exempt days / total days in year) x total Medicare levy. Flag for reviewer -- residency determination is complex.

EC2 -- Couple where one spouse has PHI and the other does not (Tier 2)

Situation: Client has private hospital cover but their spouse does not. Resolution: The MLS applies to BOTH spouses unless ALL family members (including dependants) hold appropriate cover. If the spouse is not covered, MLS is payable by both on their respective taxable incomes. Flag for reviewer.

EC3 -- Client earns just above the low-income threshold (Tier 1)

Situation: Single client with taxable income of $28,000. Resolution: Shade-in applies. Medicare levy = ($28,000 - $27,222) x 10% = $77.80. This is less than the full 2% levy of $560.00.

EC4 -- Client has net investment losses inflating MLS income (Tier 2)

Situation: Client's taxable income is $90,000 but has a net rental property loss of $15,000 (deducted from taxable income). Income for MLS purposes = $90,000 + $15,000 = $105,000. Resolution: Even though taxable income is below $97,000, income for MLS purposes exceeds $97,000 and MLS applies at 1.0% if no private hospital cover is held. Flag for reviewer -- confirm MLS income calculation.

EC5 -- SAPTO-entitled pensioner with low income (Tier 1)

Situation: Pensioner aged 68, taxable income $45,000, entitled to SAPTO. Resolution: SAPTO singles threshold is $43,020 (lower) and $53,775 (upper). At $45,000, the shade-in applies: ($45,000 - $43,020) x 10% = $198.00. Full 2% levy would be $900.00. The reduced amount of $198.00 applies.

EC6 -- Family with 4 dependent children (Tier 1)

Situation: Family with 4 dependent children, combined family income $55,000. Resolution: Family threshold = $45,907 + ($4,216 x 4) = $62,771. Family income of $55,000 is below the threshold. No Medicare levy payable.

EC7 -- MLS with private hospital cover held for part of year (Tier 2)

Situation: Client held appropriate PHI for 200 days of the year, no cover for 165 days. Single, income for MLS purposes $120,000. Resolution: MLS is pro-rated for the 165 uncovered days. MLS = $120,000 x 1.25% x (165/365) = $678.08 (approximately). Flag for reviewer -- confirm exact uncovered days.

Section 8 -- Reviewer escalation protocol

Section 9 -- Test suite

Test 1 -- Standard Medicare levy, no reduction

Input: Single, Australian resident, taxable income $80,000. Has PHI. Expected output: Medicare levy = $80,000 x 2% = $1,600.00. No MLS (has PHI).

Test 2 -- Low-income reduction (single)

Input: Single, taxable income $30,000. No spouse. Expected output: Shade-in applies. Levy = ($30,000 - $27,222) x 10% = $277.80.

Test 4 -- MLS Tier 1 (single, no PHI)

Input: Single, income for MLS purposes $105,000. No private hospital cover. Expected output: Medicare levy = $105,000 x 2% = $2,100.00. MLS = $105,000 x 1.0% = $1,050.00. Total Medicare-related charges = $3,150.00.

Test 5 -- MLS Tier 3 (single, no PHI)

Input: Single, income for MLS purposes $200,000. No private hospital cover. Expected output: Medicare levy = $200,000 x 2% = $4,000.00. MLS = $200,000 x 1.5% = $3,000.00. Total = $7,000.00.

Test 6 -- Family below family threshold

Input: Family, 2 dependent children, combined family income $50,000. Expected output: Family threshold = $45,907 + ($4,216 x 2) = $54,339. Family income $50,000 < $54,339. No Medicare levy payable.

Test 7 -- Foreign resident full exemption

Input: Foreign resident for the full year. Taxable income $60,000 (Australian-sourced). Expected output: Full Medicare levy exemption. Levy = $0. Must complete item M1.

Test 8 -- MLS family threshold with children

Input: Family, 3 children, combined income for MLS purposes $200,000. No PHI. Expected output: Family MLS threshold = $194,000 + ($1,500 x 2 children after the first) = $197,000. Income $200,000 > $197,000. MLS Tier 1 = 1.0% applies.

Section 10 -- Prohibitions and disclaimer

Prohibitions

• Prohibitions list — - NEVER apply the Medicare levy to a confirmed full-year foreign resident who is not enrolled in Medicare - NEVER ignore the MLS income definition -- it is NOT the same as taxable income (includes reportable fringe benefits and net investment losses) - NEVER tell a client they avoid MLS simply because their taxable income is below $97,000 -- check income for MLS purposes - NEVER apply the general low-income threshold ($27,222) to a SAPTO-entitled senior -- use the SAPTO thresholds ($43,020 / $53,775) - NEVER assume PHI eliminates MLS unless the cover is "appropriate" (private patient hospital cover with excess no more than $750 singles / $1,500 families) - NEVER present Medicare levy figures as definitive -- always label as estimated and direct client to their ATO assessment for confirmation - NEVER advise on diplomatic or prescribed overseas forces exemptions -- escalate - NEVER confuse the Medicare levy (2% on taxable income) with the Medicare Levy Surcharge (1%-1.5% on MLS income for those without PHI) -- they are separate charges
