The short answer

What is tax planning?

Tax planning is the work done during the year that legally lowers what you owe, before the year closes. Tax preparation reports what already happened. In New York, where state, city and federal taxes stack, planning is where the savings are.

When it happens

Preparation

January to April, after the year is over

Planning

All year, while there is still time to act

Why it matters more in New York

New York stacks taxes. Planning is how you unstack them.

National advice misses the New York layer. These four are where most of our clients were overpaying before they came to us.

Up to 14.776%

State and city tax on top of federal

New York State's top rate is 10.9% and New York City residents add up to 3.876%. Yonkers residents pay a surcharge on their state tax. Where you live, and where you work, changes the math.

8.85%

New York City ignores the S corp election

An S corporation saves self-employment tax federally, but New York City taxes S corps under its General Corporation Tax as if they were regular corporations. The right entity for a Brooklyn business is not always the right one for a Westchester business.

$40,400

The 2026 SALT cap, and who loses it

The federal deduction for state and local taxes rose to $40,400 for 2026, but it shrinks back toward $10,000 once income passes $505,000. New York's pass-through entity tax (PTET) can move business income around the cap, if the election is made on time.

15.3%

Self-employment tax on every dollar of profit

Sole proprietors and single-member LLCs pay Social Security and Medicare on nearly all of their profit, before income tax. Higher earners in the MTA region can owe the MCTMT on top. Entity choice and retirement plans are the two biggest levers.

What goes into your plan

Eight levers we check for every client

Not every lever fits every person. The plan only includes the ones that fit you, with a dollar estimate next to each.

Entity choice and S corp election

Once profit is steady, an S corp can move part of it out of self-employment tax with a reasonable salary. We run the numbers with New York State and New York City rules in, not just federal.

Good fit: Business owners with steady profit

Retirement plans that double as tax cuts

Solo 401(k), SEP IRA or a defined benefit plan. The right one can shelter tens of thousands of dollars a year, and salary deferrals through S corp payroll have to happen by December 31 to count for this year.

Good fit: Owners, self-employed and high earners

New York PTET and the SALT cap

Partnerships and S corps can elect New York's pass-through entity tax, so state tax is paid and deducted at the business level instead of being lost to the SALT cap. The election for each year is due by March 15.

Good fit: Owners of partnerships and S corps

Timing income and big purchases

When you invoice, when you buy the truck or equipment, and when you take a bonus all move tax between years. Section 179 and 100% bonus depreciation make the timing worth planning.

Good fit: Owners with lumpy income or big purchases

Deductions owners miss

An accountable plan for home office and phone costs, documented vehicle mileage, putting your children on payroll properly, and renting your home to your business for meetings under the 14 day rule.

Good fit: Every business owner

Estimated taxes, set right

Pay enough to avoid penalties, but not so much that you lend the IRS money for free. We use the safe harbor rules and adjust the payments when your income changes.

Good fit: Self-employed and anyone with a side business

Investments, giving and family

Harvesting losses, bunching charitable gifts through a donor advised fund, New York 529 contributions that are deductible on your state return, and gifts to family inside the annual exclusion.

Good fit: High earners and families

Real estate and rental property

Depreciation done properly, cost segregation on larger buildings, the rules for a rented unit in the two-family house you live in, and planning a sale before it happens.

Good fit: Landlords and real estate investors

Tax planning is the work done during the year that legally lowers what you owe, such as choosing the right business entity, funding the right retirement plan, and timing income and purchases. It happens before the year ends. Tax preparation, by contrast, reports what already happened.
