Calculators

Tools built around real decisions, not just arithmetic.

These calculators are AI-generated planning tools provided for general estimation only. Feldman Financials CPA, PLLC makes no representations as to their accuracy and accepts no responsibility for decisions made based on their output — always confirm your actual numbers with us before filing.

Quarterly estimate calculator

ESTIMATED QUARTERLY PAYMENT
$7,500
Annual estimate: $30,000

Rough planning estimate only — assumes a flat effective rate and does not account for the Social Security wage base, deductions, credits, or state tax. Talk to us for the actual number.

Self-employment tax calculator

ESTIMATED SE TAX (15.3%)
$12,713
Half deductible on your 1040: $6,357

Applies the standard 92.35% net-earnings factor and the combined 15.3% Social Security + Medicare rate. Doesn't account for the annual Social Security wage base cap.

S-corp election: side-by-side

NO ELECTION — SE TAX ON FULL PROFIT
$21,203
WITH S-CORP — PAYROLL TAX ON SALARY ONLY
$10,710
ESTIMATED ANNUAL SAVINGS
$10,493

Rough estimate of self-employment/payroll tax avoided on profit paid as a distribution rather than salary — doesn't include S-corp payroll filing costs or the wage base cap. "Reasonable salary" is an IRS requirement, not a free choice; we'd help you set the right number.

Sales tax calculator

SALES TAX DUE
$88.75
Total with tax: $1,088.75

Combined state + local rates as of 2026. A few New York cities and special districts vary slightly from their county's general rate, and New Jersey has narrow Urban Enterprise Zone exceptions — confirm the exact rate for your address before filing.

PTET estimator (NY, NJ, CT)

ESTIMATED PTET LIABILITY
$54,800

New York and New Jersey use graduated brackets up to 10.9%; Connecticut is a flat 6.99%, but owners only receive a credit for 87.5% of what the entity pays. Each state's base, election window, and credit mechanics differ — this estimates the entity-level tax only. NY and NJ elections are due March 15; Connecticut's is now elective, made with the timely-filed return.

Home office deduction (simplified method)

ESTIMATED DEDUCTION
$900
$5 per sq ft, capped at 300 sq ft

The IRS simplified method: $5 per square foot of home office space, up to 300 sq ft ($1,500 max). The actual-expense method (a share of your real mortgage/rent, utilities, and insurance) sometimes yields more — worth comparing with us before you file.

1099 contractor vs W-2 employee: true cost

TRUE COST AS W-2 EMPLOYEE
$66,600
TRUE COST AS 1099 CONTRACTOR
$60,000

Employer overhead includes the employer's 7.65% FICA match plus typical unemployment insurance and workers' comp. This is a cost comparison only — worker classification is a legal question, not a cost choice, and getting it wrong carries real IRS risk. Ask us before you decide.

Rental property cash flow & cap rate

MONTHLY NET OPERATING INCOME
$2,100
CAP RATE
5.6%

Cap rate = annual net operating income ÷ purchase price, before financing and before depreciation. Doesn't account for your mortgage, cost segregation, or passive activity rules — the details that usually decide whether a deal actually pencils out after tax.

Take-home pay estimator

ESTIMATED NET PER PAYCHECK
$2,447
Estimated annual net: $63,631

Adds the fixed 7.65% employee FICA share to your assumed income-tax rate. Doesn't account for pre-tax deductions (401(k), health insurance) or local tax.

Mileage deduction estimator

ESTIMATED DEDUCTION
$2,680

The IRS standard mileage rate changes every year — the figure above is a placeholder. Ask us for this year's official rate before you file.

Retirement contribution (SEP-IRA) estimator

ROUGH SEP-IRA CONTRIBUTION ROOM
$21,203

Uses the common ~20%-of-net-self-employment-income approximation after deducting half of SE tax. A Solo 401(k) sometimes allows a larger contribution at the same income — worth comparing before you commit to either. We'll calculate your exact limit.

Refund Trackers

State refunds are tracked separately from your federal refund, through each state's own tax agency. Pick yours below.

Don't see your state? Florida, Texas, and a handful of others have no state income tax, so there's nothing to track. For anywhere else, let us know and we'll point you to the right tool — or just ask on your next call.

Frequently Asked Questions

The questions we hear most often, answered here so you don't have to schedule a call to ask.

Do you only work with clients in New York?

No. While we're based in Brooklyn and serve a lot of New York and New Jersey clients, a significant part of our practice is multistate and national — especially for business owners and real estate investors with activity in more than one state.

What's actually included in the advisory retainer?

Monthly or quarterly bookkeeping review, the four planning checkpoints outlined on our homepage, and ongoing access to ask questions as decisions come up — instead of paying per question or waiting until filing season.

I already have a bookkeeper. Can you still help?

Yes. We regularly work alongside an existing bookkeeper — we focus on the tax strategy and entity-level decisions, and coordinate with whoever's keeping your books day to day.

How do I get my documents to you?

Through the client portal, which is the fastest and most secure way to upload documents, sign forms, and message us. We can also walk you through it on your first call.

What if I'm already being audited or I'm behind on filings?

Reach out as soon as possible. We handle IRS representation directly and can usually help even if you're mid-audit or several years behind — the sooner we're involved, the more options are typically available.

What's the difference between the free call and the comprehensive consultation?

The free 15-minute call is a quick conversation to see if we're a good fit and answer any immediate questions. The comprehensive consultation is a full hour, built around your actual tax documents and business details, and ends with concrete tax-saving strategies and a real plan — that's the one that gets into the specifics.

Do you work with real estate investors specifically?

Yes — real estate investors are one of our core client types. We work regularly on cost segregation, passive activity rules, and entity planning across a growing portfolio of properties.

Can you help if I'm just starting a new business?

Definitely. Entity choice and initial setup are far easier to get right on day one than to untangle later, and we work with founders from the very beginning of the process.

What tools or software do you use to manage my books?

We work primarily in QuickBooks, along with other cloud-based accounting tools, so your numbers stay accessible and current rather than locked in a spreadsheet that's months out of date.

How much do your services cost?

It depends on the scope of the work — most ongoing clients are on a monthly or quarterly advisory retainer rather than a flat per-form fee. The comprehensive consultation is the best way to get an actual number for your situation.

Dec 1 – Feb 28/29 periodMarch 20

PTET election deadlines

New York PTET election (for that same tax year)March 15
New Jersey BAIT election (with that year's return, the following spring)March 15
Connecticut PTET electionWith timely return

These aren't the same deadline twelve months apart. New York requires the election before the tax year it covers even ends — miss March 15 and the 2026 election is gone for good. New Jersey's BAIT election instead rides along with that year's return, so the 2026 election isn't due until March 15, 2027. PTET/BAIT elections are annual and generally irrevocable once made. All dates shift when they land on a weekend or holiday; confirm this year's exact dates with us.
