Streamlined filing cost: an honest pricing guide

Figures relate to tax year 2025 (US)

The streamlined filing cost is mostly a professional fee, because the tax itself is often zero. Quotes for the same person can still differ by thousands. Why? Because firms price different scopes, seniority and aftercare under one label — so the skill of buying well is reading what a quote includes.

So this guide is about price, not procedure. It breaks a quote into its component parts and shows which facts genuinely move the number up or down. It also flags the corner-cutting hiding behind bargain offers. By the end, you can compare any two quotes on substance instead of headline totals.

Key takeaways

• Professional fees are the real cost — the IRS charges nothing, and most UK-based filers owe little or no tax.
• Complexity drives price: investment funds, companies and rentals add genuinely extra forms.
• Fixed fees agreed in writing beat hourly billing for catch-up work.
• Scope questions expose the difference between quotes faster than the totals do.
• The cheapest offers usually exclude the pieces — PFICs, state returns, the narrative — that decide the outcome.

What are you actually paying for?

Reconstruction, mostly. Someone rebuilds three years of your finances across two countries from statements, payslips and pension records. Then everything gets presented on American forms, with a signed narrative explaining the history. Filing is the quick part at the end.

• Three years of Form 1040 returns with the expat schedules — credits or the earned income exclusion
• Six years of FBARs, each account at its highest balance, converted at the right rates
• The Form 14653 non-willful narrative — the piece that most deserves senior time
• Consistency checks between every document, because contradictions invite questions
• Assembly and submission in the format the IRS streamlined unit expects

That narrative deserves emphasis in any fee conversation. It carries a perjury declaration and gets read against everything else in the envelope. So senior time spent there is money well allocated — our Form 14653 guide shows what good looks like.

What do firms actually charge?

For a salary-and-savings case, complete packages from specialist firms typically land in the low thousands. Complexity climbs from there, with each extra form family adding real work. Ultra-cheap online offers sit below that range, and the gap is almost always missing scope rather than efficiency.

Why does the streamlined filing cost vary so much?

Because scope hides in the fine print of every quote. One firm prices the full package, while another prices bare returns and sells the rest as extras. Both call it the same product. Comparing totals without a scope list is buying blind, so ask these questions in writing:

• FBARs included, or billed per year on top?
• PFIC forms included, or 'quoted separately if required' — the classic surprise
• State returns covered where a state still claims you?
• The 14653 narrative written by a senior specialist, or from a template?
• Post-submission support if the IRS asks questions — included or hourly?

Reading a quote in five minutes

A good quote answers four questions on its face, and silence on any of them is itself an answer. Before comparing totals, check each candidate against this short list:

• What exactly is included, form by form?
• Who does the work, and at what seniority?
• What happens to the price when scope grows mid-engagement?
• What support follows the submission if the IRS writes back?

Also look for the document request. However confident the price, a firm quoting without seeing your account list is guessing, and guesses get revised later — always upward. In practice, the best predictor of a smooth engagement is a firm that asks good questions before naming any number at all. Curiosity up front is what certainty later is made of.

Fixed fee or hourly: which pricing model wins?

Fixed, agreed in writing, for almost every catch-up case. Hourly billing puts the efficiency risk on you, and reconstruction work is exactly where hours balloon. A fixed fee makes the firm own its own speed, while a written scope stops the fee quietly growing through extras.

One refinement helps both sides: staging. Part on instruction and part on completion is common, fair and easy to agree. What should never stage is the submission itself, because the returns, FBARs and certification travel to the IRS together as one indivisible package.

Is the tax itself part of the cost?

Usually barely. UK rates generally exceed American ones. So foreign tax credits wipe most or all of the US bill for UK residents, and many accepted packages show $0 due across all three years. Interest touches only whatever small balance survives the credits.

The exceptions are predictable. US-source income, large gains and PFIC funds create real balances. So do self-employment years without a totalization certificate. According to the IRS streamlined guidance (opens in a new tab), the foreign track waives the penalties entirely — the fee buys that outcome done right.

The cost of doing nothing instead

Every fee looks different next to the alternative. Outside the program, late-filing penalties run 5% of unpaid tax per month, up to 25%. That schedule sits in the IRS penalty rules (opens in a new tab). FBAR penalties then stack separately, adjusted for inflation each year.

Meanwhile the program has no guaranteed lifespan. It exists by IRS policy rather than statute, and eligibility ends the moment an examination opens. So the honest comparison is never fee versus free. It is a known fee now, against an unknown exposure on someone else's timetable.

Nobody ever regretted the fee for the package that worked. The expensive version is the cheap one done twice.

A worked example

Take an illustrative example. A teacher in Leeds has salary, two bank accounts and a workplace pension. Her package is the baseline: three straightforward returns, six FBARs, a clean narrative. Credits wipe her tax to $0, so her streamlined filing cost is the fixed professional fee alone.

Her neighbor looks identical on paper — same salary, same town. But he holds three ISA funds bought in 2019. Those funds are PFICs, each needing Form 8621 for each of three years. That is nine extra computations, so his package costs materially more, and correctly so.

How long does the work take?

Typically four to eight weeks from complete documents to submission, driven mostly by how fast banks and pension providers respond. The IRS then processes quietly for months afterward. Because you are compliant from the submission date, that waiting period rarely matters in practice.

Timing affects price in one way worth knowing. Rush jobs against an IRS contact deadline cost more, when they are possible at all. Reconstruction under pressure means premium hours, courier fees and compressed review. So the calm version of this project is also the cheap version — one more argument for starting the work before anyone makes you start it.

How do you keep the cost down?

The fee follows the hours, and the hours follow preparation. A tidy file shaves real money off the same package. In other words, the lowest streamlined filing cost belongs to the best-organized client, so work this list before requesting any quote:

1. Gather six years of statements for every account before engaging anyone.
2. Pull P60s, P45s and pension summaries for the three return years.
3. List every account with its highest balance per year — our FBAR Threshold Calculator helps frame the list.
4. Flag the complexity honestly up front: funds, companies, rentals, trusts.
5. Ask each firm the five scope questions above, in writing.
6. Choose a fixed fee agreed in writing over an open hourly rate.
7. Move promptly — reconstruction gets harder and dearer as banks purge old records.

The cheap-quote traps

In our practice we see the aftermath of bargain packages every year. The repair always costs more than the original job would have. And the patterns repeat with remarkable consistency:

• Template narratives that read like everyone else's — and draw exactly the scrutiny they should prevent.
• PFIC forms skipped entirely, leaving the riskiest asset class unreported.
• FBARs filed with year-end balances instead of highest balances.
• State returns ignored while California or Virginia still consider you theirs.
• No support when the IRS writes back, because support was never in the price.
• Quotes that swelled mid-engagement once 'extras' appeared — the fixed fee that wasn't.

None of this means expensive equals good. It means the quote must name its contents. A complete package at a fair price beats both the bargain and the premium mystery. For the program mechanics behind all this pricing, see our streamlined route guide.

How US UK Tax Accountants prices it

Our streamlined catch-up service runs on fixed fees agreed in writing before work begins. Every quote follows a real look at your documents. It lists everything: returns, FBARs, the narrative, any PFIC or company forms, and post-submission support. One senior specialist owns the file throughout. Once the catch-up is complete, our US UK accountants page explains how both returns are handled together each year.

Where your case is genuinely simple, the quote says so and prices accordingly. Where it is not, you hear the reasons in plain language before committing rather than after. Either way, the number you agree at the start is the number you pay at the end.
