IRC § 6166 (full section — closely-held business estate tax installment election)

IRC § 6166 Closely-Held Business Estate Tax Installment Calculator

Screen an estate's eligibility for IRC § 6166 installment payment of the federal estate tax attributable to a closely-held business interest — the 35% qualifier under § 6166(a)(1) (closely-held value vs. Adjusted Gross Estate), the deferrable-tax allocation, the 2% special interest rate under § 6601(j) on the tax attributable to the first $1,850,000 of closely-held value (2025 figure, indexed under § 6166(b)(7)) with the remainder at 45% of the § 6621 underpayment rate, the 14-year payment schedule (4 years interest-only under § 6166(f) followed by 10 annual installments under § 6166(a)(3)), the acceleration triggers under § 6166(g), and the NPV savings vs. paying the deferrable tax up front. Multi-business aggregation under § 6166(c) requires each aggregated business to be at least 20% of the decedent's interest in that business. Tool, not advice — § 6166 elections are irrevocable, require a timely-filed Form 706, and carry security/lien obligations under § 6324A; engage estate counsel and a CPA before relying on the election.

IRC § 2001(c) (40% federal estate-tax rate)

Federal Estate Tax Portability (DSUE) Calculator

Estimate the federal estate tax owed under IRC § 2001(c) at the 40% rate, the deceased spousal unused exclusion (DSUE) available for porting to the surviving spouse under IRC § 2010(c)(4), and the Form 706 filing deadline under Treas. Reg. § 20.2010-2 (9 months from death, 15 months with a timely Form 4768 extension). Surfaces the 2026 inflation-adjusted basic exclusion of $14.45M per individual under the pre-sunset (TCJA-extended) regime — and the post-sunset reversion to roughly $7M if the 2017 Tax Cuts and Jobs Act doubling is allowed to expire. Models lifetime taxable gifts (Form 709), the unlimited marital deduction under IRC § 2056 (US citizen spouse), the charitable deduction under IRC § 2055, and administration deductions. The single most important planning insight: file Form 706 even when no tax is owed, to preserve the deceased spouse's unused exclusion for the survivor.

F.S. Chapter 475 (Real Estate Brokers

Florida Real Estate Broker E&O Insurance Calculator

Estimate the total annual Errors & Omissions (E&O) insurance premium for a Florida real estate licensee or brokerage under F.S. Chapter 475. Florida does not statutorily mandate E&O — Chapter 475 is silent on the question — but virtually every active Florida brokerage requires E&O on every sales associate and broker associate as a condition of affiliation, and most national franchises (Re/Max, Keller Williams, Coldwell Banker, Berkshire Hathaway HomeServices, EXP) impose the requirement at the franchise level. The calculator compares the per-licensee individual-policy stack against a brokerage-wide policy, applies the Florida Realtors statewide group plan discount (typically 20%) for FAR members, models the post-Surfside (2021) coastal-Florida underwriting tightening at brokerage-tier mid-points, and surfaces the cheaper structure with a plain-English recommendation. Outputs the total annual premium, the per-licensee math, the brokerage-policy math, and the FAR group plan dollar savings.

F.S. § 193.155

Florida Save Our Homes Portability Calculator

Quantify the property-tax savings you can port from one Florida homestead to the next. Florida's Save Our Homes amendment (F.S. § 193.155, Florida Constitution Art. VII § 4(d)) caps annual assessed-value increases on a homestead at the lesser of 3% or CPI. F.S. § 193.155(8) lets you carry the accumulated SOH differential — capped at $500,000 — to your new homestead via Form DR-501T. Upsizers port the full lesser-of figure; downsizers port a proportional share. This calculator computes the differential, the portable amount after cap and proration, the new homestead's assessed value, year-1 property tax savings at your county's millage rate, and 10-/20-year cumulative savings.

F.S. Chapter 733 (formal administration)

Florida Probate Costs Calculator

Estimate the total cash cost of administering a Florida estate under F.S. Chapter 733 (formal administration) or F.S. § 735.201 (summary administration). Computes the attorney's presumptively reasonable fee under the F.S. § 733.6171(3) statutory schedule, the personal representative's fee under F.S. § 733.617, filing and publication costs, and the recommended administration path given total estate value (excluding the Florida-homestead residence, which passes outside probate under Fla. Const. Art. X § 4 and F.S. § 732.401). Florida imposes no state estate tax; the only estate-tax exposure is the federal estate tax under IRC § 2001, which applies only above the IRC § 2010 unified-credit exemption.

F.S. Chapter 732 (Florida Probate Code

Florida Estate Planning Cost Calculator

Estimate the total cash cost of a Florida estate-plan stack — simple will (F.S. Chapter 732), revocable living trust (F.S. Chapter 736), durable power of attorney (F.S. Chapter 709), designation of health-care surrogate (F.S. § 765.202), living will (F.S. § 765.302), HIPAA authorization, pour-over will, and trust funding — at attorney-drafted or DIY-template price points. Surfaces missing-element warnings (revocable trust with no pour-over will, revocable trust with no trust-funding service, testamentary instrument with no durable POA or health-care advance directive), Florida-specific complexity surcharges (out-of-state property, blended family, business ownership), and the conventional 5×-to-10× attorney-vs-DIY price premium. Florida homestead descent restrictions under Fla. Const. Art. X § 4 and F.S. § 732.401 are flagged as a fact-specific analysis attorney drafting performs and templates do not.

F.S. § 733.6171 (compensation of attorney for the personal representative

Florida Probate Attorney Fee Calculator

Estimate the Florida probate attorney's presumptively reasonable compensation under F.S. § 733.6171(3). The attorney's fee is SEPARATE from the personal representative's own compensation under F.S. § 733.617 — both run against the same estate but on different schedules. Computes the flat-fee bands on estates up to $100,000 ($1,500 / $2,250 / $3,000), the layered percentage tiers above $100,000 (3% / 2.5% / 2% / 1.5% / 1%), the multiple-attorneys shared-fee rule under § 733.6171(8), the will/agreement override under § 733.6171(3) and (2), and the court-discretionary extraordinary-services add-on under § 733.6171(4).

Michigan Compiled Laws § 207.504 (County Real Estate Transfer Tax

Michigan Real Estate Transfer Tax Calculator

Compute the Michigan real estate transfer tax that the county Register of Deeds collects when a deed is recorded — the state SRETT of $3.75 per $500 (MCL § 207.526, 0.75%) plus the county CRETT of $0.55 per $500 (MCL § 207.504, 0.11%). Combined typical: $4.30 per $500 = 0.86% of sale price, paid by the SELLER by default. Surfaces the rarely-claimed SRETT refund under MCL § 207.526(u) when the property's State Equalized Value at sale is less than at purchase, the four common exemption categories (inheritance, trust transfer to same grantor, foreclosure, government), and a Principal Residence Exemption (MCL § 211.7cc) buyer-side note for the 18-mill school operating millage savings. Notes that Michigan — unlike NY, FL, or IL — has no mortgage recording tax.

NY Tax Law § 1402 (State RPT) + § 1402-a (State Mansion Tax)

New York Real Estate Transfer Tax Calculator

Compute every layer of New York real-estate transfer tax that can stack on a single closing — the statewide Real Property Transfer Tax (NY Tax Law § 1402, $2 per $500 = 0.4%), the State Mansion Tax on residential $1M+ (NY Tax Law § 1402-a, progressive eight-tier schedule from 1.0% to 3.9% as restructured in 2019), the NYC Real Property Transfer Tax (NYC Admin. Code § 11-2102, 1.0%-2.625% by class and threshold), and the NYC Additional Tax on residential $2M+ (NYC Admin. Code § 11-2102.1, flat 0.25%). Surfaces the customary seller / buyer allocation and flags the § 1409 LLC-purchaser disclosure requirement added by 2019 reform.

Ohio Revised Code § 319.54(G)(3) (State Mandatory Real Property Conveyance Fee) and § 322.02 (County Permissive Real Property Conveyance Fee)

Ohio Real Estate Transfer Tax Calculator

Compute the Ohio Real Property Conveyance Fee that the county auditor collects when a deed is recorded — the state mandatory fee of $1 per $1,000 (ORC § 319.54(G)(3), = 0.10%) plus each county's permissive fee of up to $3 per $1,000 (ORC § 322.02, = 0.30%). Most populous Ohio counties — Cuyahoga, Franklin, Hamilton, Summit, Montgomery, Lucas, Stark, Butler and others — charge the full $3 permissive, for a combined $4/$1,000 (0.40%). Surfaces the seller-pays-by-default convention, lists the § 319.54(G)(3)(b) exemptions (gifts to family, spouse-to-spouse, inheritance, trust transfers to the same beneficial owner, transfers to government), and flags that Ohio — unlike New York or Florida — imposes no separate mortgage recording tax.

72 P.S. §§ 9101–9196 (Pennsylvania Inheritance and Estate Tax Act)

Pennsylvania Inheritance Tax Calculator

Estimate Pennsylvania inheritance tax under 72 P.S. §§ 9101–9196 (the Inheritance and Estate Tax Act) and 61 Pa. Code Chapter 91. Pennsylvania is one of six US jurisdictions that imposes an inheritance tax rather than (or in addition to) an estate tax — the rate is keyed to each beneficiary's relationship to the decedent, not to the size of the estate. Computes the 4-tier rate schedule under § 9116: 0% for a surviving spouse or charitable/educational/governmental recipient, 4.5% for lineal heirs (children, grandchildren, parents from an adult-child decedent), 12% for siblings (full or half), and 15% for collateral heirs (nieces, nephews, cousins, friends, unrelated). Surfaces the 5% early-payment discount under § 9143 (paid within 3 months of date of death), the $3,500 family exemption under § 9111(p), the deductions under § 9127 (funeral, administration, debts, last medical), and the 9-month REV-1500 filing deadline under § 9136.
