How this calculator works

What this page estimates

This Transfer Tax Allocation Calculator is built to give a quick, browser-based estimate for transfer tax allocation. Real estate transfer taxes vary widely by state and city — know the buyer/seller split. The inputs stay on the page during normal use, and the result should be treated as an estimate for planning, comparison, or education rather than professional advice.

Calculation approach

The calculator applies the standard relationship implied by the inputs, then formats the answer so it can be checked and reused. For finance tools, the most important step is using consistent units, rates, time periods, and assumptions before comparing the result with another calculator or outside quote.

Example workflow

For example, start with a realistic value you already know, change one input at a time, and watch how the answer moves. That makes it easier to tell whether the result is being driven by the main amount, the rate, the time period, or a unit conversion.

Practical checks

Use current, real-world numbers when the result affects money, health, tax, or legal decisions.
Run a low, base, and high case when the inputs are estimates.
Check the related calculators below when the next decision depends on a different assumption.

How to interpret the transfer tax allocation result

Best use

Use the result as a planning number for comparing payments, rates, returns, tax reserves, or cash-flow choices before you request a quote or make a commitment.

Cross-check

Compare the answer with the contract, lender estimate, tax form, brokerage statement, payroll record, or invoice that will control the real-world outcome.

Watch for

Do not rely on a single optimistic rate, return, or fee assumption. Money pages work best when you run low, base, and high cases and keep professional advice separate from the estimate.

This page belongs to the Finance calculator library, so the answer should be read in the context of the decision you are modeling rather than as a universal rule.

Before relying on this transfer tax allocation estimate

Most calculator mistakes come from the inputs, not the arithmetic. Use this short audit before you reuse the answer in a spreadsheet, quote, application, or important conversation.

Confirm source numbers

Match balances, rates, fees, taxes, income, and payment dates against the lender quote, payroll record, tax form, statement, invoice, or contract.

Separate cash flow from total cost

A lower monthly payment can still cost more over time if fees, interest, taxes, or a longer term are hidden in the structure.

Run conservative cases

Test at least one higher-cost or lower-return case before using the output for a purchase, refinance, investment, loan, or tax decision.

Rerun this page when the rate, price, term, fee, tax rule, income, expense, or expected holding period changes.

Frequently Asked Questions

Who pays transfer tax?

Varies by jurisdiction. Default state custom: buyer (AL, AR, FL, GA, IL, KS, MA, MI, MN, NV, OH, PA, SC, TN, TX, WI), seller (CA, CO, CT, DE, LA, MD, NY, OR, RI, SD, WA), or split (AZ, HI, ME, MT, NC, NH, NJ, OK, UT, VA). Negotiable in contract. NY: state seller + county split + NYC buyer. CA: state seller + county split + some cities add seller tax.

Mansion tax?

NYC mansion tax: 1% over $1M + progressive bands up to 4.15% over $25M. Effective 2019. NJ mansion tax: 1% over $1M. Chicago: 0.75% base + higher tiers over $1M. Connecticut: 1.11% over $800k, add'l 2.25% over $2.5M. LA Measure ULA (2023): 4% over $5M, 5.5% over $10M. Major addition to deal cost in luxury segments.

Documentary stamp vs transfer tax?

Same concept, different names. Documentary stamp tax (FL, PA, GA, etc.): state imposes on recording. Transfer tax (NY, NJ, WA, etc.): typically assessed on sale. Realty transfer fee (NJ): state + supplemental fees. All are percentage-based on sale price or consideration. Some states exempt gift transfers, related-party transfers, or transfers at specific values.

Deductibility and basis?

Transfer tax paid by buyer: adds to property basis (not immediately deductible). Paid by seller: reduces amount realized (reducing gain). For owner-occupants: generally non-deductible as itemized expense. For investment property: deductible as selling expense (seller) or capitalized in basis (buyer). Keep documentation — transfer tax is scrutinized in IRS audits of real estate transactions.
