When to Hire a US CPA for Your Delaware LLC

Why day-90 is the right time

By Day 90, your LLC is formed, you have your EIN, your bank account is open, and you likely have first transactions.

This is the right time to engage a CPA: early enough to set up bookkeeping correctly, late enough to have something to discuss.

Many founders wait until tax season to engage a CPA. This works but rushes the relationship. Engaging early gives you time to ask questions before stakes are high.

What to look for in a CPA

Non-resident-LLC experience is non-negotiable. Form 5472 has specific rules that general CPAs sometimes miss. Ask: how many foreign-owned single-member LLCs do you currently serve?

Below 10 means relatively inexperienced; 50 plus means specialized.

Communication availability matters. Some CPAs work April-only; others are responsive year-round.

For non-resident founders in different time zones, year-round availability and email/WhatsApp responsiveness beat large-firm prestige.

Typical fee structures

Annual flat fee: $500-$1,200 for single-member LLC with moderate complexity. Includes Form 5472, pro forma 1120, basic bookkeeping review, and one consultation.

Hourly: $150-$300/hour for additional consultations or complex situations. Multi-state nexus, sales tax compliance, or M&A advisory typically triggers hourly billing.

The difference between a CPA, an enrolled agent, and a bookkeeper

Non-resident founders often use the word CPA loosely to mean anyone who handles tax. In the US system these are three distinct roles with different authority.

A CPA is a Certified Public Accountant licensed by a state board, able to sign tax returns, represent you before the IRS, and provide attest services.

An enrolled agent (EA) is federally licensed by the IRS specifically for tax matters and can also represent you in audits, but cannot perform the audit and assurance work a CPA can.

A bookkeeper records transactions but holds no license to file returns or represent you.

For a single-member Delaware LLC owned by a non-resident, any of the three can be the right starting point depending on your needs.

For the typical foreign-owned disregarded LLC, the actual return that must be filed is a pro forma Form 1120 with Form 5472 attached. Both a CPA and an enrolled agent can prepare and file this.

If your only obligation is this information return plus clean bookkeeping, an experienced EA who specializes in foreign-owned LLCs is often a sound and lower-cost choice than a full CPA firm.

The reason this post centers on CPAs is that founders search for the term, and that many founders eventually need the broader advisory work a CPA provides as they grow.

The practical takeaway is to hire for the work in front of you rather than the credential alone. Ask the person directly whether they currently prepare Form 5472 for foreign-owned single-member LLCs.

The credential matters less than whether they handle your exact situation every week. A general CPA who has never touched a 5472 is riskier than an EA who files dozens of them each season.

Why the Form 5472 penalty makes this decision urgent

The single sharpest reason a non-resident-owned Delaware LLC needs competent tax help is Form 5472. Since 2017 the IRS has treated foreign-owned single-member LLCs as reportable entities.

The LLC must file a pro forma Form 1120 with Form 5472 attached, reporting reportable transactions between the LLC and its foreign owner, even when the LLC owes no income tax.

Missing this filing, filing it late, or filing it incomplete carries a penalty of $25,000. That figure is not a typo and it is not capped at your revenue.

A dormant LLC with $0 in sales can still face the $25,000 penalty for a missed 5472.

This is why the timing question in the original post matters so much.

A founder who forms an LLC, opens a Mercury account, moves capital in, and then forgets about tax until the following spring may already be exposed.

The 5472 deadline tracks the corporate return deadline, generally April 15 for a calendar-year entity, with an extension available via Form 7004.

A CPA or EA engaged early in the year builds the filing into a calendar rather than discovering it weeks before the deadline.

The penalty structure also reframes how to think about CPA fees. An annual engagement in the $500 to $1,200 range for a single-member LLC is small next to a $25,000 exposure.

Founders who try to self-file the 5472 to save money sometimes do it correctly, but the form asks for reportable transaction categories that are easy to misread when you have never seen them.

The cost of one professional review against the penalty math is the clearest value case in this entire topic.

What a clean first meeting with your CPA should cover

When you engage a CPA inside the first 90 days, the opening conversation sets the tone for the whole relationship.

Come prepared with your formation documents, your EIN confirmation letter, your Operating Agreement, and read-only access or exports from your business bank account.

The EIN itself is free when you file Form SS-4 directly, and it usually arrives in about 8 to 10 business days for non-residents, so by Day 90 you should have it in hand.

Bringing these documents lets the CPA confirm your entity classification rather than guessing at it later.

A good first meeting establishes three things. First, your filing map for the year, which for most non-resident single-member LLCs is the pro forma 1120 plus 5472 and nothing else federally.

Second, your bookkeeping method, meaning who records transactions and in what software.

Third, your banking and payment setup, since the CPA needs to know whether money flows through Mercury, Wise, Relay, Lili, or Payoneer, and whether Stripe or a merchant of record sits in front of your revenue.

Each of these affects how reportable transactions get categorized.

The meeting should also surface what is not your obligation, which saves you money and worry.

Many non-resident owners do not owe US federal income tax, do not owe quarterly estimated payments, and do not owe Delaware state income tax on non-Delaware-source income.

Hearing a qualified professional confirm what you can ignore is as valuable as the list of what you must do. Write down each answer so you can hold the engagement to it next year.

How to vet a CPA before you pay anything

Vetting matters because the market is full of generalist firms that will happily take a foreign-owned LLC client without the specific experience to serve one well.

Start with a short written list of questions and send it before any call.

Ask how many foreign-owned single-member LLCs they currently serve, how many Form 5472 filings they prepared in the most recent season, whether they handle the entity as disregarded by default, and how they communicate across time zones.

The answers separate a specialist from someone learning on your file.

Verify the license independently. In the US you can confirm a CPA license through the relevant state board of accountancy, and you can confirm an enrolled agent through the IRS directory.

This takes minutes and protects you from the small number of people who claim credentials they do not hold.

For a non-resident paying from abroad, this verification step replaces the local word-of-mouth trust you would have at home. A legitimate professional will not be offended by the check.

Finally, test responsiveness before you commit. Send one substantive question and see how long the reply takes and how clear it is.

A firm that takes ten days to answer a pre-sales question will not improve after you pay.

For founders in Asia, the Middle East, Africa, or Latin America, a professional who answers by email or a messaging channel within a day or two is worth more than a prestigious name that only works through phone calls during US business hours.

Speed and clarity now predict the relationship later.

Bookkeeping habits that keep your CPA bill low

CPA fees scale with mess. The flat annual fee of $500 to $1,200 quoted in the original post assumes moderate complexity and reasonably clean records.

The fastest way to push your bill toward the hourly $150 to $300 range is to hand over a year of unreconciled transactions and ask the CPA to sort them out.

The work you do during the year directly controls what you pay at filing time, which means bookkeeping is a cost-control tool, not just a compliance chore.

Build a few simple habits from the first month. Keep business money strictly separate from personal money, which a dedicated account at Mercury, Wise, Relay, Lili, or Payoneer makes easy.

Categorize each transaction monthly rather than annually, so you never face a backlog. Keep digital copies of invoices and receipts in one folder named by month.

Note the purpose of any transfer between you and the LLC, because those owner-to-LLC and LLC-to-owner movements are exactly what Form 5472 reports.

A two-line note today saves an email exchange with your CPA later.

If you prefer not to touch bookkeeping at all, many CPAs and EAs that specialize in foreign-owned LLCs bundle monthly bookkeeping into their annual fee or offer it as a modest add-on.

That is a reasonable trade for founders who would rather spend time on their business.

Just confirm in writing what the bundle includes, because a fee that looks higher upfront can be cheaper than an hourly cleanup in April. Decide the model before you sign, not after.

When a single-member LLC needs more than a 5472

The simple filing picture, a pro forma 1120 with 5472 attached and no income tax due, holds for a large share of non-resident-owned LLCs that sell digital products or services to a global audience with no US physical footprint.

The moment your facts change, the filing picture changes too, and that is when an early CPA relationship pays for itself.

Knowing the triggers helps you raise your hand before a problem compounds across a tax year.

Several situations move you out of the simple lane. Effectively connected income, where your activity rises to a US trade or business, can create actual US tax and additional forms.

Amazon FBA inventory sitting in US fulfillment warehouses can create physical-presence nexus in multiple states, pulling in state-level filings and sales tax.

Hiring a US-based contractor or employee creates reporting obligations. Electing to be taxed as a C-corporation changes the entire return and can trigger quarterly estimated payments.

Each of these is manageable, but only if your CPA hears about it early.

The lesson is to treat your CPA as someone you update when facts change, not only someone you visit at deadline.

A short message saying you just enrolled in FBA, or signed your first US client, or are considering a corporate election, lets the professional adjust your filing map before the year closes.

Founders who go silent for twelve months and then reveal a major change in April pay more and risk more. The relationship works when information flows during the year.

The franchise tax that is not a CPA matter

Non-resident founders frequently confuse the Delaware franchise tax with something their CPA must calculate, and clearing this up early prevents both worry and wasted fees.

The Delaware franchise tax for an LLC is a flat $300 per year, due June 1, and it is not an income tax. It is a fee for the privilege of keeping the LLC on the Delaware register.

A profitable LLC and a dormant LLC both owe the same $300. There is no calculation, no schedule, and no relationship to your revenue.

Because it is flat and fixed, the franchise tax does not require a CPA to compute. You or your registered agent simply pay it through the Delaware Division of Corporations by June 1 each year.

Many founders ask their CPA to handle it for convenience, which is fine, but understand you are paying for an errand rather than tax expertise.

If your budget is tight, this is one task you can comfortably own yourself once you set a recurring reminder for late May.

Keep the franchise tax mentally separate from your federal information return.

The $300 to Delaware on June 1 and the pro forma 1120 with 5472 around April 15 are two unrelated obligations with two different recipients.

Missing the franchise tax leads to a $200 late penalty plus interest and eventual loss of good standing, while missing the 5472 leads to the $25,000 federal penalty.

Both deadlines belong on your calendar, but only one of them is really a CPA decision.

Coordinating your CPA with your home-country tax advisor

A US CPA solves your US filing obligations, but it does not address what you owe where you live. This is the gap that surprises founders most.

Your Delaware LLC income may be taxable in your country of residence even when it generates no US tax, because most countries tax their residents on worldwide income.

A US CPA is not licensed or positioned to advise on your home-country return, so a complete picture needs two professionals who understand how their pieces fit together.

Ask your US CPA to give you clean documentation that a home-country advisor can use, meaning a clear record of LLC income, the entity classification, and confirmation of any US tax paid or not paid.

Then take that to a tax advisor where you live, who can determine how your country treats a US disregarded entity, whether it is seen as a transparent pass-through or a separate company, and whether any tax treaty between your country and the US changes the result.

The two answers together tell you your real total tax position.

Founders sometimes assume that because the US side shows no income tax, there is nothing to pay anywhere, which is a costly assumption.

The US filing and the home-country filing are separate questions with separate answers.

Spending a modest fee on a home-country consultation in your first year, alongside your US CPA engagement, prevents a much larger surprise later.

Coordinate early so neither professional is working from incomplete facts about the other side.

Reading a CPA engagement letter before you sign

Once you choose a CPA, you will receive an engagement letter, and reading it carefully protects both sides.

The letter defines the scope of work, the fee, the responsibilities of each party, and what happens if something goes wrong.

For a non-resident paying from abroad, this document replaces a handshake you cannot give in person.

Treat it as the contract it is, and ask questions about anything unclear before signing rather than after the work begins.

Look specifically at scope and exclusions.

The letter should state plainly whether it includes the pro forma 1120 and 5472, whether bookkeeping is included or extra, how many consultations are covered, and what triggers additional hourly billing such as multi-state nexus or a corporate election.

A vague scope is where fee disputes are born.

If the letter says federal filings without naming the 5472, ask for it to be named, because that single form is the heart of your compliance and you want it explicitly covered.

Check the practical terms too. Confirm the payment method works from your country, since some US firms only accept domestic payment rails, while others use Wise, card, or international transfer.

Confirm how documents are exchanged and stored, since you will be sending sensitive financial records across borders.

Confirm what happens to your records if you end the engagement, so you can move to another professional cleanly. A clear engagement letter makes the relationship calm.

An unclear one creates friction at exactly the wrong time of year.

Signs it is time to switch CPAs

Engaging a CPA early is the goal of the original post, but staying with the wrong one is its own cost. Non-resident founders sometimes tolerate a poor fit because switching feels harder from abroad than it is.

Knowing the warning signs lets you act before a weak relationship causes a missed deadline.

The strongest signal is silence, meaning a CPA who does not respond for weeks, especially as a filing deadline approaches, is a real risk to your $25,000-exposed 5472.

Watch for a few specific patterns.

A CPA who seems unsure about Form 5472 mechanics, who keeps asking you basic questions about foreign-owned LLCs that they should already know, or who treats your entity as something other than a disregarded single-member LLC without explaining why, may simply lack the specialty.

Surprise fees with no connection to the engagement letter are another sign. So is a refusal to put advice in writing, because a professional confident in their answer will document it.

Switching is more orderly than it feels.

Wait until your current year's filings are complete if you can, request a full copy of your records and prior returns, and confirm the new professional can pick up your history.

Because the foreign-owned LLC filing pattern is standardized, a competent successor can step in smoothly with your prior 1120 and 5472 in hand.

Do not let the friction of change keep you tied to someone who is putting your compliance at risk. The relationship serves you, not the other way around.

How banking and payment choices shape your CPA work

The tools you use to move money quietly determine how much work your CPA faces, which is why the original post's fee ranges assume a tidy setup.

A single dedicated business account, whether at Mercury, Wise, Relay, Lili, or Payoneer, produces a clean transaction feed that a CPA can categorize quickly.

Spreading activity across several accounts, or mixing personal and business spending, multiplies the reconciliation work and pushes you toward hourly billing.

Your account structure is a tax-prep decision as much as a banking one.

Payment processing adds another layer. If you sell through Stripe directly, your CPA sees gross sales, processing fees, refunds, and payout timing, all of which must be reconciled to your bank deposits.

If you sell through a merchant of record such as a service that handles tax and remittance for you, the picture your CPA receives is different and often simpler, because the merchant of record sits between you and the end customer.

Tell your CPA which model you use, because it changes how revenue and fees appear in your books.

The owner-to-LLC money movements deserve special attention because they are exactly what Form 5472 reports.

Every time you fund the LLC from personal money, or take money out, that is a reportable transaction between the foreign owner and the entity.

Keeping those transfers in clearly labeled bank entries, rather than buried among operating spend, lets your CPA populate the 5472 accurately without a back-and-forth.

Your banking discipline directly produces the form's accuracy, so choose a simple setup and keep the owner transfers obvious.

Why BOI no longer belongs on your compliance checklist

For a stretch of 2024 and early 2025, beneficial ownership information reporting under the Corporate Transparency Act dominated formation checklists, and many founders still ask their CPA about it.

The position changed. Under the FinCEN interim final rule issued March 26, 2025, US-formed entities including domestic Delaware LLCs are exempt from the BOI reporting requirement.

A Delaware LLC formed by a non-resident is a US-formed entity, so it does not file a BOI report under that rule. This removes a step founders were budgeting time and worry for.

It matters here because outdated advice still circulates, and a CPA or service quoting you for BOI filing on a US-formed LLC is working from an old playbook.

When you vet a professional, you can gently test their currency by asking how they handle BOI for a domestic LLC. A sharp answer that reflects the 2025 exemption tells you they keep up.

An insistence that you must still file, or a fee attached to it, is a small flag worth noting about how current their knowledge is.

Removing BOI from the list also clarifies what genuinely remains.

Your real recurring obligations as a non-resident single-member LLC owner are the flat $300 Delaware franchise tax by June 1, the federal pro forma 1120 with Form 5472 around April 15, and clean bookkeeping underneath both.

That is a short and manageable list. Keeping it short, and not carrying retired requirements forward, is part of what an early and well-chosen CPA relationship does for you.

Pay for the obligations that exist, and let go of the one that no longer does.

Building a twelve-month rhythm with your CPA

The original post answers when to start, but the relationship is annual, so it helps to picture the full year. Think of it as a rhythm rather than a single April event.

In the first quarter after engaging, you set up bookkeeping, confirm your filing map, and document your banking and payment flows.

Through the middle of the year you keep records current month by month and send your CPA a short note whenever a material fact changes, such as a new US client, FBA enrollment, or a possible corporate election.

As the calendar year closes, your CPA assembles the pro forma 1120 and Form 5472 from the books you maintained, aiming for the April 15 deadline or an extension via Form 7004 when needed.

Separately, you handle the $300 Delaware franchise tax by June 1, which is an errand rather than a calculation.

Spacing these so the federal filing and the state fee do not collide in your mind prevents the late-spring panic that catches founders who treat all US obligations as one undifferentiated blur.

This rhythm is what makes the modest annual fee worth far more than its price.

A CPA you engage early and feed information to throughout the year produces accurate filings, flags issues before they grow, and shields you from the $25,000 5472 penalty that punishes silence and delay.

A CPA you contact once, in a rush, at the deadline, costs more and protects less. The choice in this post is not only which CPA, but how you work with them across twelve months.

Choose early, communicate often, and the compliance side of your Delaware LLC becomes quiet and predictable.
