Almost every commitment in Zohran Mamdani’s affordability agenda runs through the same bottleneck: New York City cannot raise its own income taxes without state approval. That makes Albany, not City Hall, the decisive venue. Here are twenty things to know about the fight.
1. Mamdani Cannot Raise Income Taxes Without Albany
New York City requires state authorisation to raise income taxes. This single constitutional fact shapes the entire agenda and limits what any mayor can promise unilaterally.
2. Mamdani’s Centrepiece Is The Fair Share Act
Mamdani’s Plan A would have Albany enact a two-percentage-point increase on income above $1 million.
3. Mamdani Says It Would Raise $3 Billion A Year
That is the administration’s estimate for the millionaire tax component alone, which would cover a substantial share of the budget gap.
4. Mamdani Also Wants Higher Corporate Taxes
The plan proposes raising city corporate taxes by 1.8 percentage points for finance-sector firms and 1.77 points for other corporations.
5. Mamdani Included Large Unincorporated Businesses
A smaller 0.4-point increase would apply to large unincorporated businesses, broadening the base beyond traditional corporations.
6. Mamdani’s Benefit Cap Would Add $700 Million
The plan would limit a particular tax benefit to 75 cents on the dollar, which the city estimates would generate roughly $700 million annually.
7. Mamdani Put The Taxes In His February Budget
The tax proposals were part of his first budget proposal, presented shortly after taking office.
8. Hochul Opposes Mamdani’s Millionaire Tax
She has been consistent in opposing income tax increases on high earners, both at state and city level.
9. Hochul Is More Open To Mamdani’s Corporate Ask
Reporting indicates the governor has appeared more receptive to a corporate rate increase, which creates a possible partial path forward.
10. Mamdani Revised His Albany Request In March
By March 2026 the administration had brought a modified proposal to Albany involving a smaller corporate tax increase alongside other measures.
11. Legislative Leaders Also Resist Mamdani’s Plan
Opposition is not confined to the governor’s office, which narrows the room for a straightforward legislative win.
12. Hochul Gave Mamdani Money Rather Than Authority
Rather than granting taxing authority, the state pledged an additional $1.5 billion to the city, including $500 million in recurring funds.
13. Mamdani’s Budget Gap Is Still Around $5.4 Billion
The two-year budget shortfall moved from roughly $7 billion to about $5.4 billion — an improvement, but well short of a solution.
14. Analysts Say Mamdani’s Tax Is Affordable
Fiscal analysts quoted in 2026 coverage argued a millionaire tax is workable and that concerns about high earners leaving are frequently overstated.
15. Critics Warn Mamdani’s Tax Base Will Move
Opponents argue that high earners and firms are more mobile than they once were, and that revenue projections assume behaviour that may not hold.
16. The Evidence On Mamdani’s Tax Risk Is Disputed
Research on whether state and local tax increases drive significant relocation is mixed, and both sides cite studies supporting their position.
17. Mamdani’s Fight Is Political As Much As Economic
The disagreement is not purely technical. It reflects a real difference of view within the Democratic Party about taxation and the role of city government.
18. Mamdani Has Pressured Hochul In Public
He has been willing to press the governor publicly rather than negotiating quietly, a tactic that carries risks as well as benefits.
19. Mamdani’s Free Buses Depend On This Fight
The postponement of fare-free buses was attributed directly to funding obstacles and ongoing Albany negotiations.
20. Albany Decides Whether Mamdani’s Agenda Works
If the revenue does not materialise, the housing, childcare and transit commitments cannot all be funded at the promised scale. Everything else is downstream of this.
The bottom line: The substantive argument over Zohranomics is really an argument about revenue. Mamdani has a detailed plan for raising it and no unilateral power to enact it, and until Albany resolves that question the rest of the agenda remains partly theoretical.
