99 
100### Example 1 -- Low Income
101 
102**Input:** Taxable income $22,000. Single.
103 
104**Computation:**
105- Gross Nunavut tax: $22,000 × 4.00% = $880.00
106- BPA credit: $19,274 × 4.00% = $770.96
107- Basic NU tax before Cost of Living credit: $109.04
108- Cost of Living basic credit ($12,000 × 4%) = $480.00
109- Net NU tax: −$370.96 (refundable to taxpayer)
110 
111### Example 2 -- Mid-Range
112 
113**Input:** Taxable income $85,000. Single.
114 
115**Computation:**
116- $54,707 at 4.00% = $2,188.28
117- $30,293 at 7.00% = $2,120.51
118- Gross NU tax: $4,308.79
119- BPA credit: $770.96
120- Basic NU tax: $3,537.83
121- Cost of Living basic ($480.00) plus partial supplementary; net NU tax approximately $2,800 (verify supplementary formula).
122 
123### Example 3 -- High Income
124 
125**Input:** Taxable income $300,000. Single.
126 
127**Computation:**
128- $54,707 at 4.00% = $2,188.28
129- $54,706 at 7.00% = $3,829.42
130- $68,468 at 9.00% = $6,162.12
131- $122,119 at 11.50% = $14,043.69
132- Gross NU tax: $26,223.51
133- BPA credit: $770.96
134- Basic NU tax: $25,452.55
135- Cost of Living credit fully phased out.

138 
139## Section 5 -- Edge Cases
140 
141### EC-NU-1: Cost of Living Tax Credit supplementary formula
142 
143Verify the current NU479 supplementary formula from the GN Department of Finance before computing. Conservative default: report basic credit only and flag supplementary as [T2].
144 
145### EC-NU-2: Northern Residents Deductions interaction
146 
147Federal Northern Residents Deductions (line 25500 of T1) reduce federal taxable income for residents of prescribed northern zones. ALL of Nunavut is a prescribed northern zone. Confirm the deduction is claimed federally before computing NU428; it will lower territorial taxable income proportionally.
148 
149### EC-NU-3: Inuit beneficiary income from Nunavut Land Claims Agreement
150 
151Income arising directly from the Nunavut Agreement (e.g., royalty distributions to a Designated Inuit Organization) may have specific tax treatment. Escalate.
152 
153### EC-NU-4: Mining and resource royalties
154 
155If T2125 includes Nunavut mining royalty income, escalate — interactions with the Nunavut Agreement royalty mechanism are complex.
156
