FOR PRO ATHLETES
Seven 1099 forms. Zero tax withheld. One $61,000 wake-up call.
I sat across from a 27-year-old pro tennis player who had just spread seven tax forms across his kitchen table. He'd earned $340,000 that year. He owed more than he thought was possible, and nobody had ever explained why.

The Story
In September 2023, a 27-year-old pro tennis player named Devon R. spread seven tax forms across his kitchen table. Four were 1099-NEC forms from sponsors and appearance fees. Two were 1099-K forms from the platforms that processed his coaching clinics. One was for prize money from a tournament series. Total reported income: $340,000. Total tax withheld by anyone, anywhere: $0.
The Problem
Here's what is 1099 income in plain terms: it's money nobody withholds tax from before it hits your account. Your friends on W-2 salaries have their tax handled automatically. Every dollar you make from prize money, appearance fees, or endorsement checks on a 1099 is yours in full, until the IRS comes to collect what it's owed. Add a payer list that spans tournaments, sponsors, and clinic platforms, and the math gets ugly fast.

What We Tried
Devon tried TurboTax, his dad's longtime CPA, and a bookkeeping app that was great at categorizing coffee and useless at quarterly deadlines. He set aside 25% of every check by hand, and the actual bill came in 34% higher than that guess.

The Discovery
The real problem wasn't one big mistake, it was three small ones stacked together. Self-employment tax adds 15.3% on top of income tax, and it applies to every 1099 dollar with no exceptions, before the IRS even looks at your bracket. Quarterly estimated payments are due four times a year, not once, and missing even one triggers its own penalty, calculated like interest for every day the payment sits unpaid. The messiest piece was reconciliation: a clinic platform's 1099-K reports the same coaching session an academy also reports on a 1099-NEC, so the same dollar can get counted twice unless someone lines up every form against the actual bank deposit. If most of your 1099 income comes from a small number of sponsors, a spreadsheet cross-check once a quarter usually catches the double count. If it comes from a dozen platforms and clinics the way Devon's did, only a system built to reconcile deposit by deposit catches it before the return gets filed, not after an IRS letter does.

The FixAMADAE
Devon's story didn't have to end with a $61,000 surprise. Amadae paired him with a real accountant who tracks every 1099 the moment it arrives, calculates his quarterly estimates before the deadline instead of after the penalty, and reconciles the clinic platform 1099-Ks against what payers actually sent. It's books, quarterly taxes, and entity strategy in one flat monthly fee, built for income that doesn't come with a W-2 attached.

The Proof
Devon's story isn't a one-off. Athletes on 1099 income across every sport hit the same wall the first time a big check arrives with no withholding attached. The fix is always the same: know the real number, not the guessed one.

Straight answers
A 1099 reports income nobody withheld tax from, like prize money, appearance fees, and endorsement payouts. A W-2 paycheck has taxes taken out automatically. 1099 income puts the entire responsibility, income tax and the 15.3% self-employment tax, on you. One exception: if a payer never gets a completed W-9 from you, the IRS can force them into 24% backup withholding on everything they pay you after that.
Most apps categorize expenses and draw charts. Very few calculate quarterly estimated taxes or reconcile platform 1099-Ks against sponsor 1099-NECs, which is exactly where Devon's $61,000 gap came from. Most also assume your income lands evenly across the year, which is wrong for anyone paid in lump sums after a tournament or an endorsement check clears.
Yes. The IRS expects estimated payments in the quarter you earn the income, not spread evenly across the year. A deep tournament run or an endorsement payment in one quarter can create a large payment due that same quarter.
Sometimes, depending on how much of your income is 1099-based and how consistent it is. An S-corp also means paying yourself a reasonable salary through actual payroll, which is a compliance step consumer tax software never sets up for you. It's not automatic, which is why we review your actual numbers on a free call instead of guessing.
