Morris County is one of New Jersey’s most affluent counties — home to major corporate campuses, top-ranked public schools, and a high concentration of executives, professionals, and business owners. The average household income in towns like Chatham, Madison, Mountain Lakes, and Chester significantly exceeds state and national medians. That wealth profile creates specific tax challenges: high property taxes, SALT cap limitations, AMT exposure, and the frequent need to coordinate federal and NJ tax planning for equity compensation and capital gains.
Morris County Property Taxes: High and Largely SALT-Capped
Morris County’s average annual property tax bill exceeds $11,800 — and in affluent towns, it’s significantly higher:
| Municipality | Avg. Annual Property Tax | Notes |
|---|---|---|
| Chatham Borough | ~$16,800 | Top-tier suburb; NJ Transit access |
| Madison | ~$14,500 | Downtown, walkable; high demand |
| Mountain Lakes | ~$18,200 | One of NJ’s highest-rated school districts |
| Chester Township | ~$10,900 | More rural; lower values |
| Parsippany | ~$9,800 | Large corporate campus presence |
| Morristown | ~$11,400 | County seat; urban core + suburbs |
| Roxbury | ~$7,900 | More affordable end of the county |
| Mine Hill / Wharton | ~$6,800 | More modest properties |
For most Morris County homeowners, property taxes alone exceed the $10,000 federal SALT cap — meaning the deduction is fully capped on the federal return regardless of how much you pay. NJ’s own property tax deduction (up to $15,000 on the NJ-1040) provides partial relief at the state level.
ANCHOR: Most Morris County Households Near or Above Income Limits
The ANCHOR benefit phases out at $250,000 household income. A significant portion of Morris County households exceed this threshold — particularly in Chatham, Madison, Mountain Lakes, and Chester. However, many Morris County residents in Rockaway, Roxbury, Dover, Victory Gardens, and Wharton do qualify for the full $1,500 benefit. Check your income relative to the limit before assuming you don’t qualify.
High-Earner Tax Issues Specific to Morris County
Executive Compensation and Equity
Morris County is home to major employers including Honeywell, Pfizer (Parsippany), AT&T, and numerous pharmaceutical and financial firms. Many residents receive RSUs, stock options, or significant bonuses. Key NJ-specific issues:
- NJ taxes capital gains as ordinary income — no preferential rate. RSU vesting creates ordinary income taxable in both NJ and federally; subsequent sales of the shares create capital gain taxable at NJ ordinary rates (up to 10.75% for income over $1M)
- Incentive Stock Options (ISOs): NJ does not conform to federal ISO treatment. ISO exercises may trigger NJ income in the year of exercise (unlike federal where AMT is the primary issue)
- Deferred compensation: NJ has specific rules for when deferred compensation becomes taxable that differ from federal timing
AMT and High-Income Planning
Morris County residents with incomes above $500,000 face NJ’s 8.97% rate; above $1 million, 10.75%. Combined with federal income tax, Medicare surtax (3.8% on net investment income), and the federal AMT, total marginal rates on investment income can reach 50%+ for high earners. Strategies worth exploring with a CPA include qualified opportunity zone investments, charitable bunching, and retirement plan maximization.
