Tax Strategy Built for High-Stakes Multi-State Businesses.

Short-term gains (assets held one year or less) are taxed at your ordinary income rate—up to 37% federally. Long-term gains (held more than one year) are taxed at preferential rates of 0%, 15%, or 20% depending on income.

High earners may also owe the 3.8% Net Investment Income Tax (NIIT) once MAGI exceeds $200,000 (single) or $250,000 (married filing jointly).

A Section 1031 exchange lets you sell investment or business real estate and defer 100% of the capital gain by reinvesting the proceeds into "like-kind" replacement property. The tax isn't eliminated—it's deferred, rolling your basis into the new property.

Strict timing rules apply: you must identify replacement property within 45 days and close within 180 days of the sale. A qualified intermediary must hold the proceeds—you can never touch the cash.

How a second home is taxed depends entirely on how you use it. A pure personal residence allows mortgage interest and property tax deductions (within the SALT cap), but no rental deductions. A pure rental lets you deduct expenses and depreciation but follows passive activity rules.

The trap is the mixed-use property. If you rent it out more than 14 days a year and also use it personally, expenses must be allocated, and the "14-day / 10% rule" determines whether it's treated as a residence or a rental. The §121 exclusion ($250k single / $500k married) that shelters gain on a primary residence generally does not apply to a second home.

The IRS sorts income into active (wages, business income you materially participate in), portfolio (interest, dividends, capital gains), and passive (rental activities and businesses you don't materially participate in).

The distinction matters because passive losses can generally only offset passive income—not your W-2 wages. Suspended passive losses carry forward until you have passive income or dispose of the activity. Real estate professionals and those who qualify for the $25,000 active rental loss allowance are key exceptions.

US citizens and green-card holders are taxed on worldwide income, no matter where they live. The Foreign Earned Income Exclusion (FEIE), claimed on Form 2555, lets qualifying expats exclude a large chunk of foreign earned income (wages, self-employment) from US tax.

To qualify, you must meet either the Bona Fide Residence test or the Physical Presence test (330 full days abroad in a 12-month period). The exclusion covers earned income only—passive income like dividends and capital gains is always taxable. A separate Foreign Housing Exclusion can shelter additional qualifying housing costs.

The Foreign Tax Credit (Form 1116) gives you a dollar-for-dollar credit against US tax for income taxes you've already paid to a foreign government. Unlike the FEIE, it applies to both earned and passive income and scales with your actual foreign tax paid.

For Americans in high-tax countries (Germany, France, the UK), the FTC often eliminates US liability entirely while preserving access to credits like the Child Tax Credit. In low-tax countries (UAE, certain territories), the FEIE may deliver more relief. The two can sometimes be combined—but switching from FEIE to FTC triggers a five-year lockout without IRS approval.

The FBAR (FinCEN Form 114) is required if the aggregate value of your foreign financial accounts exceeded $10,000 at any point during the year—even for a single day. It's an informational filing, not a tax, but the penalties for non-filing are among the harshest in the code.

A separate but overlapping requirement, FATCA Form 8938, is filed with your tax return at higher thresholds. Many expats must file both. Penalties for willful FBAR violations can reach 50% of the account balance per year.

Expats get an automatic two-month extension to June 15 to file (though tax owed is still due April 15). Beyond FEIE and FTC, expat planning weaves together totalization agreements for Social Security, treaty positions, foreign pension treatment, and the new 1% excise tax on certain outbound remittance transfers.

Self-employment tax remains "sticky"—the FEIE won't shield it, though a totalization agreement may. State tax can also follow you abroad if you keep a "sticky" domicile in a state like California or New York.

The Child Tax Credit (CTC) is worth up to $2,200 per qualifying child under 17, with up to $1,700 refundable through the Additional Child Tax Credit. Recent legislation made the $2,200 amount permanent with future inflation indexing.

The credit begins to phase out at $200,000 (single) and $400,000 (married filing jointly). A key recent change: the taxpayer, spouse, and each qualifying child must now have a work-eligible Social Security number to claim it.

A 529 plan grows tax-free, and withdrawals are tax-free when used for qualified education expenses—college tuition, room and board, and up to $10,000/year for K-12 tuition. Many states (including New York and New Jersey) offer a state income tax deduction for contributions.

Contributions count as gifts, so you can front-load up to five years of the annual gift exclusion in one year ("superfunding"). Unused funds can be rolled to another beneficiary, and a limited amount can now be rolled into a Roth IRA for the beneficiary under certain conditions.

Two credits offset tuition costs. The American Opportunity Tax Credit (AOTC) is worth up to $2,500 per student for the first four years of undergrad, and 40% of it ($1,000) is refundable. The Lifetime Learning Credit (LLC) is worth up to $2,000 per return for any post-secondary or job-skills coursework, with no year limit.

Both phase out for higher earners (AOTC ends at $90k single / $180k joint MAGI). You can't claim a credit on expenses you also paid with tax-free 529 funds—coordination matters.

Real tax planning happens before December 31, not at filing. For our individual clients, we run a mid-year projection to forecast liability, then layer in moves: bunching itemized deductions, timing capital gains and losses, accelerating or deferring income, charitable strategies (donor-advised funds, appreciated stock), and retirement contribution optimization.

For high earners we also model AMT exposure, NIIT, the SALT cap (now raised to $40,000 for many filers), and estimated payment safe harbors to avoid underpayment penalties.

The most common misconception: W-2 employees cannot deduct home office expenses on their federal return. The 2017 tax law suspended unreimbursed employee business expenses through 2025 (and recent legislation has largely continued this), so remote employees generally get nothing federally—an employer accountable-plan reimbursement is the workaround.

The home office deduction is available to the self-employed and independent contractors who use a space regularly and exclusively for business. They can use the simplified method ($5/sq ft up to 300 sq ft) or actual expenses.

New York's "convenience of the employer" rule says that if you work for a NY-based employer but work remotely from another state for your own convenience (not because your job requires it), New York still taxes those days as NY-source income.

This catches NJ and CT residents who work from home for a Manhattan employer. They can be taxed by both NY (on the income) and their home state—relying on a resident credit to avoid full double taxation, which doesn't always fully offset.

You take the larger of the standard deduction or your itemized total. For 2025 the standard deduction is $15,750 (single) and $31,500 (married filing jointly), with extra amounts for those 65+.

Itemizing is worthwhile when mortgage interest, charitable gifts, and state/local taxes exceed the standard amount. The SALT deduction cap was raised to $40,000 for many filers under recent law—reopening itemizing for high-property-tax households in NY and NJ who'd been capped out.

If you have income without withholding—RSU vesting, investment gains, self-employment, K-1 income—you likely owe quarterly estimated payments. Miss them and the IRS charges an underpayment penalty even if you pay in full by April.

You're protected by a safe harbor if you pay the lesser of 90% of this year's tax or 110% of last year's tax (for higher earners). Paying to the safe harbor lets you defer the rest interest-free until filing.

An LLC (Limited Liability Company) is a legal structure that separates your personal assets from business liabilities. For taxes, an LLC is a chameleon: by default a single-member LLC is a "disregarded entity" (reported on your Schedule C), and a multi-member LLC is taxed as a partnership.

Crucially, an LLC can elect S-Corporation taxation. Once profits are high enough, this split—reasonable salary plus distributions—can save meaningful self-employment tax, since distributions aren't subject to the 15.3% SE tax.

Nexus is the connection that lets a state impose tax obligations on you. Physical nexus comes from an office, employees, inventory, or property in a state. Economic nexus—established after the 2018 Wayfair decision—is triggered purely by sales volume, with most states using a threshold around $100,000 in sales or 200 transactions.

For individuals, nexus shows up as multi-state income tax when you work, own rental property, or hold a business interest across state lines. A single remote employee can create both income tax and payroll nexus for an employer in that worker's state.

If you move mid-year or split time across states, you'll likely file as a part-year resident in each, allocating income to the period you lived there. People who work in one state and live in another file a nonresident return in the work state and claim a resident credit at home for taxes paid elsewhere.

Watch the statutory residency trap: spending 183+ days in a state like New York while keeping a permanent home there can make you a full resident—taxed on all income—even if you're domiciled elsewhere.

New Jersey's Business Alternative Income Tax (BAIT)—and similar pass-through entity taxes now offered by most states—lets an S-Corp or partnership pay state income tax at the entity level. That tax is fully deductible federally, effectively sidestepping the individual SALT cap for the owners.

Owners then receive a credit on their personal NJ return for their share of the BAIT paid. For profitable pass-throughs, the federal savings can reach thousands per owner annually.

Federal estate and gift tax share a single lifetime exemption—a large amount you can transfer tax-free during life or at death—above which a 40% federal rate applies. You can also give up to the annual gift exclusion per recipient each year without touching that lifetime amount.

The exemption is historically high right now but is scheduled to change, so families with significant assets benefit from planning while the window is favorable. New Jersey no longer has an estate tax, but does still impose an inheritance tax on transfers to certain non-lineal beneficiaries.

A trust or estate that earns income generally files Form 1041. The key concept is that income is taxed either to the trust/estate or to the beneficiaries who receive distributions—and trust tax brackets compress quickly, hitting the top rate at a very low income level.

That compression makes distribution timing a real planning lever: income kept in the trust can be taxed far more heavily than the same income distributed to a beneficiary in a lower bracket.

Transferring a business—to children, partners, or a buyer—triggers some of the most consequential tax decisions an owner ever faces. The structure of the deal drives whether gains are taxed as capital gains or ordinary income, how much estate and gift tax applies, and how a step-up in basis is captured.

Tools like gifting shares over time, grantor trusts, installment sales, and buy-sell agreements each have very different tax outcomes. Done well, succession planning preserves both the business and the family's wealth; done late, it can force a sale just to pay the tax.

Ultra-high-net-worth families rarely have simple returns. Wealth is layered across partnerships, S-corps, trusts, real estate in several states, and sometimes foreign holdings—each with its own filing, basis tracking, and state-sourcing questions.

The risk isn't usually a single big mistake; it's the cumulative drag of uncoordinated entities, missed elections, and state exposure no one mapped. Pulling it into one coherent, year-round strategy is exactly the multi-entity, multi-state work this practice was built around.
