FlyFin costs about $84/year for AI deduction tracking, or $192–$348/year to have a dedicated CPA prepare and file your federal and state returns for you. After running it through a full tax season across three real freelance businesses, here is how many write-offs the AI actually found, what the CPA caught that the AI missed, and the income level where the $192 plan stops being the obvious pick.

Our FlyFin deductions dashboard for Briar & Vale after a full tax season on the Standard plan ($192/year). Visible: $13,920 in AI-flagged deductions across 16 months of linked transactions, $4,600 of which were write-offs we were not already tracking (about $1,100 in tax) — and the part the marketing skips, an 88% precision rate that needs a human yes-or-no on every flag, plus three sizeable deductions the AI missed entirely and our dedicated CPA had to add by hand.
Quick verdict
Most freelancers either overpay a CPA every spring or undersell themselves on deductions trying to do it alone. FlyFin's pitch is that it solves both at once: an AI scans your linked bank and card accounts year-round to flag every deductible transaction, and then a dedicated human CPA prepares and files your federal and state return for you. This FlyFin review 2026 is about whether that AI-plus-CPA combination actually earns its price — around $84/year for tracking alone, or $192 to $348/year if you want the CPA to do your taxes too.
We ran FlyFin through a full tax season across three real freelance businesses with deliberately different profiles — one expense-heavy designer on the $192 Standard plan, one near-zero-expense copywriter on the ~$84 Basic tracker-only plan, and one S-Corp photographer on the $348 Premium plan — linking real bank and card accounts, letting the AI scan up to 16 months of history, and having FlyFin's CPAs prepare and e-file real returns. We tracked how many write-offs the AI found, how many were wrong, what the CPA added on top, the turnaround time, and the income level where the math stops working.
Spoiler verdict: for a freelancer with real business expenses who would otherwise pay a CPA anyway, FlyFin's done-for-you filing is strong value and the AI scan genuinely finds money — but the AI is the assistant, the CPA is the product, and the cheap tracker-only tier is the one plan we would tell most people to skip.
How we tested FlyFin
Entity one was Briar & Vale (sole-proprietor freelance illustrator and brand designer, ~$83K in 2025 revenue, Schedule C, expense-heavy: software, a drawing tablet, home office, travel to client studios) — the ideal FlyFin user, run on the $192 Standard plan with a business checking account and a business credit card both linked. Entity two was Theo Brandt (freelance copywriter working from a spare bedroom, almost no business expenses, ~$58K, filing jointly with a W-2 spouse) — deliberately put on the ~$84 Basic tracker-only plan to find where FlyFin is not worth it. Entity three was Quay Street Studio (S-Corp-elected single-member LLC freelance photographer, ~$142K, shoots in two states, pays quarterly estimates, hired a second-shooter contractor) — on the $348 Premium plan to test S-Corp filing, multi-state returns, the CPA video calls, and the audit insurance.
Across the season we tracked how many deductible transactions the AI flagged versus how many were genuine, how much incremental tax each freelancer actually saved, what deductions and strategies the FlyFin CPA added that the AI had not surfaced, the time from document handoff to e-filed return, and how close FlyFin's quarterly estimate landed to a CPA's independent number. Read our full review methodology.
Because we filed real returns on real freelance income and let the AI scan real linked accounts, every precision rate, dollar figure, and turnaround number in this FlyFin review has the underlying transaction and filing data behind it — this is the AI-tax layer that sits directly on top of the bookkeeping and deduction tools we have reviewed across the rest of the site.
Key findings
- FlyFin's AI flagged 262 deductible transactions across 16 months on our heaviest-expense freelancer; 231 held up and 31 were false positives — 88% precision, and every flag still needed a human yes-or-no
- The AI surfaced $4,600 of untracked write-offs (~$1,100 in tax at a ~24% combined rate); the dedicated CPA then added ~$1,150 more in deductions the AI had missed — together roughly 6× the $192 plan
- On Premium, S-Corp reasonable-comp planning saved our $142K photographer about $3,200 in self-employment tax — something the tracker-only tools can't do
- On a near-zero-expense freelancer, the AI found just $430 of deductions all year (~$103 in tax) — less than the $192 CPA-filing plan would cost
What FlyFin does well
The AI finds the write-offs — then a real CPA finds the ones the AI missed
This is the heart of FlyFin, and on the right freelancer the two halves compound. Once you link a bank account or card, the AI scans up to 18 months of history and flags every transaction it thinks is deductible, then keeps watching new charges as they land. On Briar & Vale it flagged 262 deductible charges worth $13,920, of which $4,600 were write-offs she was not already tracking — a forgotten font-license subscription, the business slice of her phone and internet, a conference fee. At her roughly 24% combined income-and-self-employment rate, that is about $1,100 in tax she would otherwise have overpaid.
But the AI alone left money on the table. When FlyFin's CPA reviewed the return, they added three things the algorithm never surfaced: the home office calculated under the actual-expense method rather than the simplified rate (worth $540 more in deduction), a reconstructed mileage log for client visits ($612), and a suggestion to open and fund a SEP-IRA that deferred roughly $1,900 in tax. That is the part the “AI does your taxes” marketing skips: the human is where the last and largest chunk of value lives.
A dedicated CPA actually prepares and files the return — state filing included
The difference between FlyFin and a self-service tool is who does the work at the end. FlyFin is genuinely done-for-you: you upload your documents, answer a short interview, and a dedicated CPA prepares the federal and state return, asks any clarifying questions in chat, and e-files once you approve. On Briar & Vale the federal-plus-one-state return came back prepared in six business days, with a single round of questions we cleared in chat within a day. Crucially, all state filing is included in the plan price — there is no per-state fee, which is where seasonal filers quietly add $60 to $70 each.
S-Corp filing and reasonable-comp planning the tracker tools can't touch
FlyFin's Premium plan files S-Corp returns, and for a higher-earning freelancer that is where the real tax move lives. On Quay Street Studio — an S-Corp-elected LLC clearing ~$142K — the CPA set a defensible reasonable salary, took the remainder as distributions exempt from self-employment tax, and filed the 1120-S plus the personal 1040 with two-state apportionment. The net saving was about $3,200 in self-employment tax for the year, after accounting for the extra payroll and admin an S-Corp requires. The multi-state return took nine business days to prepare, and we used two of the included 30-minute CPA video calls to walk through the salary split and a depreciation question.
FlyFin is best understood as an AI write-off radar bolted to a real CPA — and on the right freelancer it is the CPA, not the algorithm, that turns it from a nice gadget into a tool that pays for itself.
Where FlyFin falls short
88% precision means the AI is a first pass, not a filer
FlyFin's marketing says the AI “eliminates 95% of your work” and finds “every possible deduction.” In practice it does neither on its own. On Briar & Vale, of 262 transactions the AI flagged as deductible, 31 were false positives we had to reject — a personal grocery run tagged as a business meal, a clothing purchase, a family streaming subscription. That is 88% precision: good for an automated scan, but it means you are still reviewing every flag, because claiming those 31 would have overstated her deductions to the IRS. And as the dashboard above shows, the AI also missed deductions a human caught. “Every possible deduction” describes the AI-plus-CPA pairing, not the AI by itself.
It's slower than doing it yourself — not an April-14 tool
Because a human prepares the return, FlyFin runs on the CPA's clock, not yours. Our simplest return (Briar & Vale, federal plus one state) took six business days from document handoff to e-filed; the S-Corp multi-state return took nine. That is fine if you start in February, but it rules FlyFin out as a last-minute option — a self-service tool like a guided filer can have a simple Schedule C done in under an hour the night before the deadline. If you are the kind of freelancer who files on April 14, the done-for-you model will stress you out rather than save you time.
The cheap tier is tracker-only, and the low-expense case doesn't pay off
Two value problems. First, the ~$84 Basic plan strips out the thing that makes FlyFin worth buying — the CPA filing — and leaves you with a deduction tracker and a quarterly estimator but no return filed. You still need a separate filer, so for a simple return you are paying $84 on top of a free or cheap filing tool that already prompts you for common deductions. Second, the CPA-filed Standard plan is overkill for a genuinely simple tax situation: on Theo Brandt, the low-expense copywriter, the AI found just $430 of deductions all year (about $103 in tax), and a joint return with one straightforward Schedule C files free through IRS Free File or for around $73 elsewhere. FlyFin earns its keep on expenses and complexity; without those, the cheaper tools win.

✓ What we liked
- AI surfaced $4,600 of untracked write-offs on Briar & Vale — about $1,100 in tax, then the CPA added ~$1,150 more
- A dedicated CPA prepares and files the federal and state return for you — genuinely done-for-you
- All state filing included in the plan price — no per-state fees stacking up
- Premium files S-Corp returns — reasonable-comp planning saved ~$3,200 in SE tax on our $142K photographer
- Quarterly estimator landed within $75 of an independent CPA's figure
- Two included 30-minute CPA video calls on Premium made the S-Corp salary split easy to get right
✗ What frustrated us
- 88% precision — we rejected 31 false-positive flags, including personal charges tagged business
- The AI missed real deductions (actual-expense home office, mileage log) that only the CPA caught
- CPA-prepared returns took 6–9 business days — useless for last-minute filers
- The ~$84 Basic tier is tracker-only and files nothing — weak value on its own
- Near-useless for low-expense freelancers — just $430 found on Theo Brandt all year
- No phone line for ad-hoc help — contact is in-app chat with your assigned CPA, plus video calls on Premium
Who should pay for FlyFin?
Buy it if: You are a freelancer with real, recurring business expenses who would otherwise pay a CPA to file anyway. That is exactly where FlyFin shines: the AI scan finds the deductions, and a dedicated CPA prepares and files the return for a flat price that undercuts most hourly accountants. The $192 Standard plan is the one most full-time sole proprietors and single-member LLCs want — AI tracking plus a CPA-filed federal and state return with no per-state fees. Step up to Premium ($348) if you are taxed as an S-Corp or partnership, want the CPA video calls, or want the audit insurance, as our $142K photographer did.
Skip it if: You work from home with almost no overhead — on Theo Brandt the AI found just $430 of deductions all year, well under the cost of the filing plans. If your taxes are genuinely simple, a guided filer or free filing covers them: TurboTax is more polished for a self-serve return and many low-income filers can file federal for free. And if you want to stay hands-on and self-file with just a tax-pro looking over your shoulder rather than handing the whole return to a CPA, our reviewed Keeper is the closer fit. FlyFin is also wrong for last-minute filers — the CPA turnaround needs weeks, not hours.
Try before you buy: FlyFin offers a 7-day free trial that lets you link an account and see what the AI scan turns up before it charges you. That is the right way to test it: connect your main business card, let it scan, and look at the dollar value of write-offs it surfaces that you were not already tracking. If that number is comfortably above ~$800, the $192 Standard plan will pay for itself; if it is a few hundred dollars, you do not have enough expenses to justify a CPA-filed plan over a cheaper tool. Set a reminder to cancel before day 7 if you are only testing.
FlyFin FAQ
Final verdict
FlyFin does the thing it promises: on a freelancer with real business expenses, the AI scan finds money you would otherwise leave with the IRS, and then a dedicated CPA prepares and files the whole return for a flat price that beats most hourly accountants. It surfaced $4,600 of untracked deductions on our heaviest-expense tester, the CPA added another ~$1,150 the AI had missed, and on our S-Corp photographer the reasonable-comp planning saved about $3,200 in self-employment tax — all for $192 to $348 a year with state filing included.
The honest limits are about trust and timing. At 88% precision the AI flags personal charges as business and still misses real deductions a human has to add, so it is the CPA, not the algorithm, that closes the gap. The done-for-you model runs on the CPA's clock — six to nine business days — so it is no help to a last-minute filer, and the ~$84 Basic tier files nothing, which makes it weak value on its own.
Recommended for: expense-heavy freelancers and self-employed pros who would pay a CPA anyway and want the AI scan and the filing handled in one place — the $192 Standard plan is the sweet spot, with Premium reserved for S-Corps. Skip it if you work from home with little overhead, file at the last minute, or want to stay hands-on with your own return.
