Bookkeeping for High Net Worth Individuals in Miami

The short answer is that it is not one set of books. It is usually six or nine sets that all have to agree with each other. A family we take on typically arrives with an operating business, a management company, a few property LLCs, a holding entity, and sometimes a family partnership sitting on top of the whole stack. Each of those is its own reporting unit with its own ledger and its own year-end. Treating them as one pile is where the damage starts, and it is the most common condition of the books we inherit.

So the work starts with structure rather than data entry. One chart of accounts, mirrored across every entity, so that Repairs means the same thing in the Brickell building that it means in the Coral Gables building. A bank feed per entity, reconciled every month rather than every quarter. An intercompany clearing account in each ledger, so that when the management company pays a vendor bill for a property LLC the entry lands as a receivable on one side and a payable on the other instead of as an unexplained expense in whichever account happened to hold cash that week.

After structure comes the monthly cycle. Every account reconciled to a statement. Every card charge coded to an entity and to a purpose. Loan payments split between interest and principal rather than dumped into one line, because a principal payment is not a deduction and the ledger has to know the difference. Owner draws recorded as draws instead of as expenses. Capital spending pulled out of the repair accounts and parked on a fixed asset schedule where it belongs. None of that is exotic. It is just done consistently, which is the part that turns out to be rare. The IRS recordkeeping guidance and Publication 583 describe the floor, and the floor sits well below what a nine-entity family actually needs.

A worked example. A client came to us with four entities and roughly 31,000,000 dollars of net worth, mostly real estate. The prior bookkeeper ran a single ledger and used classes to separate the properties. It looked fine on screen. When we unwound it, 214,000 dollars of construction spending on one building had been coded to repairs across three years, and 46,000 dollars of the client’s personal spending sat inside the operating company as office expense. Neither error was fraud. Both were the predictable result of one ledger doing the work of four. Fixing it took eleven weeks and produced two amended returns.

The Miami piece changes the shape of the work in a specific way. Florida has no state personal income tax, which is why a good number of our clients moved here in the first place, and it means the books do not carry a state income accrual line for the individuals or for the pass-through entities. That removes a running estimate that a New York or California package would need every month. It does not remove the state entirely. The Florida Department of Revenue administers sales tax and reemployment tax, so any entity with staff or taxable sales carries those liabilities on the balance sheet like any other payable. Everything else in the ledger points at the federal return, which is the quiet truth about bookkeeping for high net worth clients in Miami.

The mistake we see most often is hiring for speed instead of for structure. A family hires a capable bookkeeper who closes fast and produces tidy statements, and nobody notices for four years that the fixed asset schedule was never built and that depreciation is being estimated each spring from a folder of invoices. Clean-looking output from a ledger with no asset detail is worse than messy output, because it stops anyone from asking questions.

This is why our bookkeeping engagement is scoped around the entity map first and the transaction volume second, and why it runs alongside tax strategy consulting rather than behind it. The ledger is where planning either becomes real or quietly does not. Build it right at the start of a year and the return the following spring is a printing exercise instead of a reconstruction project, which is the whole point of doing this work properly in the first place.

Separate ledgers, always. The temptation with a family that owns eight buildings is to run one set of books with a class or a tag per property. It reports fine until something goes wrong, and something always goes wrong. Entities have separate legal existence and separate tax filings, and a ledger that pretends otherwise will eventually produce a number that cannot be traced back to a bank statement. We run one ledger per entity and consolidate upward for reporting, never the reverse.

Inside a property entity, the unit of measurement is the property, not the entity. Each building gets its own income and expense detail, because Schedule E reports rental activity property by property, and because a portfolio-level number tells you nothing about which building is bleeding. Publication 527 covers the rental rules that drive the coding decisions, including what counts as rental income and how personal use of a property changes the treatment. A Key Biscayne house the family uses six weeks a year is not the same tax animal as a pure rental, and the books have to know that on the day the transaction posts, not the following March.

Then there is the intercompany traffic, which is where most multi-entity ledgers fall apart. Management fees. Cash sweeps. One entity covering another’s insurance premium because that account had the balance that morning. Each of those needs a matching entry in both ledgers and a periodic true-up so the balances actually agree. When they do not agree, the consolidated statement double counts income and the tax returns contradict each other. We reconcile intercompany balances monthly and settle them at least once a year in cash or by written note, so the paper trail matches the accounting trail.

A worked example. A family partnership owned six rental buildings across two LLCs plus a management company. The prior books ran everything through the management company’s operating account and pushed a year-end journal entry to allocate the costs. The allocation was a percentage rather than a tracing. When we rebuilt it property by property, one building that had been showing roughly 40,000 dollars of annual profit was actually losing about 18,000 dollars a year once its own insurance and its own debt service sat against it. The family had been subsidizing that building for six years without knowing it. They sold it fourteen months later.

That is what bookkeeping for high net worth clients in Miami has to deliver. Not just a return that files, but a ledger that answers a question the family actually has. Which building is working, and which entity is quietly carrying the others. The recordkeeping rules set the retention standard, and the accounting method choices described in Publication 538 govern when income and expense land, which matters a great deal more with several entities than with one.

The mistake here is the year-end allocation. It feels efficient. One entity pays everything and the accountant sorts it out later with a journal entry. Later never has the information that the moment of the transaction had. Nobody remembers in February which of two buildings the 9,000 dollar roof patch was for, and the invoice shows the vendor’s address rather than the property’s.

Our bookkeeping work is built around per-entity ledgers and per-property detail from the first day, and it feeds directly into the individual return where the Schedule E detail eventually lands. Get the coding right at the transaction and every downstream report gets easier for years, which is the compounding return that nobody bothers to advertise.

Longer than you want and in more detail than you expect. Publication 583 sets out the basic recordkeeping expectation for a business, and the IRS recordkeeping page lays out the retention periods, which run from three years in the ordinary case out to six years where income was substantially understated, and with no expiration where no return was filed at all. For a family holding property, the practical answer is longer still, because basis records have to survive until three years after the year you sell the asset. A closing statement from 2004 can matter in 2031.

Then there is the substantiation tier, which is stricter than general recordkeeping. Publication 463 governs travel, meals, gifts, and car expenses, and it does not accept a credit card statement as proof. The rule wants the amount, the date, the place, and the business purpose, recorded at or near the time of the expense. That last part is the one that fails. A reconstruction built in April from a calendar and a card feed is not a contemporaneous record, and an examiner is not required to accept it. Deductions in this category get disallowed for documentation more often than for legitimacy.

Car expense is the clearest case. The standard business mileage rate for 2026 is 72.5 cents per mile through June 30 and 76 cents per mile from July 1, and taking it requires a log showing the date, the mileage, and the purpose of each trip. A client driving between four buildings and an office builds real mileage. At 9,000 business miles a year, that is about 6,525 dollars of deduction resting entirely on whether the log exists. No log, no deduction, and the underlying driving was never in dispute.

A worked example from an examination. A client ran roughly 84,000 dollars a year through the management company for travel and client meals across two businesses. The spending was real and the business purpose was real. The documentation was a card feed coded to Meals with no notes attached. Under exam, roughly 61,000 dollars of it came out for failure to meet the Publication 463 standard, and the tax plus interest ran near 27,000 dollars. Nothing about the underlying facts changed. Only the paper did.

What we ask families to keep is narrower than everything and wider than the tax return. Bank and card statements with the underlying receipts for anything above the firm’s threshold. Closing statements and improvement invoices for every property, kept permanently, because those build basis. Entity documents, loan agreements, and the notes behind intercompany balances. Payroll records where there are staff. The business expense rules decide what is deductible in the first place, and the records decide whether the deduction survives contact with a reviewer.

The mistake is assuming that Florida’s lack of a personal income tax lowers the documentation burden. It does not. It removes a state return, not a federal one, and the federal record standard is the one doing the work. The documentation standard behind bookkeeping for high net worth clients in Miami is federal rather than local, and the Florida Department of Revenue still expects sales and reemployment tax records from any entity that has them. Families relocating from New York sometimes arrive with the reasonable but wrong idea that the whole compliance layer got lighter when they crossed the state line.

Our bookkeeping engagements build the substantiation capture into the monthly close rather than leaving it to a year-end scramble, and the same records feed tax strategy consulting whenever a position needs support. Records are cheap to make on the day and expensive to reconstruct three years later, and a family that builds the habit early rarely has to think about it again.

This is the account that decides the tax bill, and it is the account that is almost always wrong when we take over a set of books. A repair is deducted in the year paid. An improvement is capitalized and depreciated across years, and it also raises basis, which lowers the gain when the property sells. Same invoice, same vendor, two completely different outcomes depending on what the work actually did to the building. Publication 551 covers basis and what gets added to it.

The test looks at the work rather than the amount. Fixing a broken pipe is a repair. Replumbing the building is an improvement. Patching a section of roof after a storm is a repair. Replacing the roof is an improvement. The line is whether the work betters the property, restores it after it has been substantially worn out, or adapts it to a new use. Miami’s climate makes this a live question rather than an academic one, because storm damage and salt air produce a steady stream of invoices that could plausibly sit on either side of the line.

Once something is capitalized it goes on a fixed asset schedule with a placed-in-service date and a recovery period. Publication 946 sets out how depreciation works, residential rental property runs 27.5 years and nonresidential runs 39 years under the general system, and the deduction gets reported each year on Form 4562. Land is never depreciated, which means every purchase needs a land-to-building allocation on the day it closes. Guessing that split later, or leaving it at whatever the county assessor happened to use, costs money in both directions.

A worked example. A client spent 340,000 dollars on a Coconut Grove rental over two years. The prior bookkeeper coded all of it to repairs and maintenance. About 295,000 dollars of it was a gut renovation of the kitchens and the bathrooms plus a new roof, which is capital work. The rest, roughly 45,000 dollars, was genuine repair. The error deducted 295,000 dollars too early, which was the visible problem, and it also left basis 295,000 dollars too low, which was the invisible one. When the building sold four years later the understated basis would have added roughly 70,000 dollars of federal tax on the gain. We rebuilt the schedule before the closing.

Publication 527 ties the rental rules together and is the reference we hand clients who want to understand why the coding matters this much. There is also a piece almost nobody catches on their own. When the old roof comes off and a new one goes on, the old roof is still sitting on the depreciation schedule with basis left in it. That remaining basis can often be written off in the year of the replacement rather than depreciated for another two decades on a component that no longer exists.

The mistake is treating the invoice total as the unit of decision. Contractors do not bill in tax categories. A single 120,000 dollar invoice routinely contains capital work and deductible repair work inside the same document, and the only way to split it correctly is to ask the contractor for detail while the job is still fresh. Six months later the answer is a guess wearing a suit.

Because Florida has no state personal income tax, the entire cost of this decision is federal, which makes the fixed asset schedule the most valuable document in the file. It is also where bookkeeping for high net worth clients in Miami earns its fee. Our bookkeeping work maintains that schedule as a living record instead of a spring reconstruction, and our tax strategy consulting team reviews it before any property changes hands. Get it right while the invoices are still in front of you and the family gets paid twice, once in the current deduction and again years later on the gain.

More than people think, and the cost shows up in places nobody connects back to the ledger. The obvious one is the disallowed deduction. Personal spending run through an entity is not a business expense under the business expense rules, which require an expense to be both ordinary and necessary for the business. A boat slip and a housekeeper paid out of the management company come out under examination, and they bring interest along with them.

The second cost is the harder one. Commingling attacks the story. An examiner who finds five personal charges stops treating the ledger as reliable and starts sampling everything else, and the examination widens from one issue into the whole return. The deductions that were legitimate now have to be proven one at a time rather than accepted as a class. That shift is worth far more than the personal charges themselves. No return is beyond an audit, and the goal is not to be untouchable. The goal is to be boring to look at.

The third cost is legal and it sits outside tax entirely. Entities exist to separate assets. A ledger showing that the property LLC routinely paid the family’s household bills is the same evidence a creditor’s attorney uses to argue the entity was never really separate. We are accountants rather than lawyers, and that question belongs to the client’s attorney, but the books are where the answer gets written down over the course of years without anyone deciding to write it.

A worked example. A client ran roughly 96,000 dollars a year of household spending through an S corporation and treated it as expense across three years, about 288,000 dollars in total. The examination disallowed the deduction, which cost tax and interest at the flow-through level, and the same money then got recharacterized as a distribution, which raised its own questions about basis and about whether the owner’s W-2 wages were reasonable for the work performed. The total cash cost landed near 134,000 dollars. Every dollar of it was avoidable with a second bank account and a distribution entry.

The fix is unglamorous. The entity pays entity costs. When the owner wants money, the entity makes a distribution, or pays a wage if it is an S corporation with an owner working in the business, and the personal spending happens from the personal account. The bookkeeping cost of doing it this way is close to zero. The bookkeeping cost of not doing it is a reclassification project and a defensible-position argument later. Publication 463 governs the mixed-use categories where the line genuinely blurs, such as a car used for both purposes, and the answer there is a log rather than a guess.

The mistake we see most is the convenience card. One card, used for everything, with a sincere intention to sort it out monthly. It never gets sorted out monthly. Six weeks in, the coding becomes a memory exercise, and within a year the ledger has quietly become a mixed-use document that nobody can defend. Families who want this cleaned up before it turns into an exam problem can request a consultation, and we will start with the card statements, because that is where it always is.

This is the least interesting part of bookkeeping for high net worth clients in Miami and the part that saves the most money. Our bookkeeping engagements separate the spending at the account level rather than at the coding level, and the cleaned-up result feeds the individual return without an argument. The IRS small business guidance is blunt about keeping business and personal funds apart, and a family that draws that line early never has to redraw it under pressure.
