Tax Planning Starts Before the Return: Why CPA Judgment Matters More in a Cross-Border World

Some of the most expensive tax problems do not begin during tax season. They begin much earlier, when a client forms an entity, buys property, transfers money, changes residency, sells an asset, or builds an ownership structure without first understanding the tax impact.

This becomes even more serious when more than one country is involved. A decision that looks simple in one jurisdiction can trigger foreign reporting, withholding, ownership disclosures, penalties, or years of complex filings in another.

To explore why tax planning must happen before the return is prepared, Ace Cloud Hosting spoke with Ron Abraham, CPA, Partner at KSDT. With nearly 13 years in the accounting industry, Ron works with individuals, businesses, and real estate investors on U.S. tax compliance, international tax matters, and cross-border planning.

His work focuses on helping clients understand their filing obligations, the tax impact of major decisions, and the importance of getting advice before the facts are already set.

In this conversation, Ron explains why early planning matters, where cross-border tax risks often appear, how CPAs can move clients into year-round advisory conversations, and where AI can support tax professionals without replacing human judgment.

1. Why do the most expensive tax problems often begin before the tax return is ever prepared?

The most expensive tax problems usually begin long before anyone opens the tax software. It all starts when a client forms an entity, moves to another country, sells an asset, transfers money between companies, buys U.S. real estate, or creates an ownership structure without first understanding how that decision will be viewed from a tax perspective and whether it was done right.

By the time the return is being prepared, the facts are already set and it’s hard to make major adjustments. At that point, we are often not planning anymore. We are reporting what happened and trying to minimize the damage as much as possible. I see this a lot in cross-border situations because what may feel simple and harmless in one country can create a completely different result in another.

A very common example is someone living outside the U.S. who plans to move to the U.S. If they speak with a U.S. international tax professional before becoming a U.S. tax resident, there may be planning opportunities available. For example, they may own foreign investments, foreign mutual funds, ETFs, or other financial assets that could create PFIC issues once they become a U.S. person. In some cases, we may be able to restructure, sell, or clean up those investments before U.S. residency begins.

That one conversation before the move can save years of complicated reporting, unfavorable tax treatment, and unnecessary professional fees. Once the person is already a U.S. tax resident, many of those options may be gone.

2. In cross-border tax situations, what are the biggest risks clients miss when they make decisions without consulting a CPA first?

One of the biggest risks clients miss is that each country may view the same transaction differently. A structure that is efficient in one country may create a completely different result in the U.S., including income recognition, foreign reporting, withholding, or ownership disclosure requirements. Clients often focus on the business deal itself and assume the tax reporting can be cleaned up later. In many cases, that is where the problem begins.

Another major risk is penalties. Foreign bank accounts, foreign corporations, foreign-owned U.S. entities, foreign trusts, partnerships, and ownership structures can all carry reporting requirements that are separate from whether tax is actually owed. A client may think, “I did not make any money, It is okay if I don’t report it,” but the IRS may still require certain forms whether there is a tax attached to it or not with significant penalties for non-filing.

For example, a missed Form 5471 for an ownership in a foreign corporation can start at $10,000 per form, per year, and a missed Form 5472 for a foreign-owned U.S. corporation or foreign-owned disregarded LLC can start at $25,000 per form, per year. Missed FBAR filings can also be costly, especially when multiple years are involved.

These are the things my team and I are dealing with on the daily basis and as their trusted advisor we have to do everything we can to protect them by avoiding these costly mistakes.

3. How can CPAs move clients away from last-minute filing conversations and into year-round planning discussions?

I think CPAs have to stop allowing the relationship to be built only around tax filing deadlines. It needs to be more relationship-focused and less transaction-focused. If the only time we speak with clients is when we are asking for documents, then we should not be surprised if they decide to leave us to another firm. We must be proactice rather than reactive, espacially in this environment.

One practical way to change that is by asking better questions throughout the year. Not just, “Send me your bank statements,” but “Are you planning to sell anything this year?” “Are you planning to acquire a business ?” “Are you moving money between countries?” “Are you investing in U.S. property?” “Are you planning to have a residency change?” “Did ownership change?”

Clients do not always know what is important, so we have to educate them. I also think CPAs should use real examples. A client understands planning much better when you explain, “If you call me before the transaction, we may have options. If you call me after, we may only have reporting obligations.”

That shift changes the relationship from compliance to advisory.

4. Where do you see AI helping tax professionals today, and where does human judgment still matter most?

AI is a very powerful tool, and I use it as a way to become more efficient, organized, and thoughtful. Even for projects like this, where I am trying to organize my thoughts and communicate them clearly, AI can help reduce the time spent on the first draft by more than 80%. It can help summarize rules, draft client explanations, organize research, compare concepts, and speed up the first layer of analysis. For a busy CPA, that is valuable because it creates more room for higher-level thinking. AI allows you to become a “Super Accountant” if you use it wisely.

But and it’s a very big but, AI shouldn’t replace judgment, collaboration or critical thinking, especially in cross-border tax. International tax is not just about finding a rule. It is about understanding the client’s facts, the business purpose, the treaty position, the reporting requirements, the foreign country treatment, and the practical risk of taking a certain position

Many times, two answers can both sound technically reasonable, but only one makes sense for that client. That is where experience matters. AI can help with the work, but it cannot sit with the client, challenge assumptions, understand the full picture, implement or take responsibility for the conclusion.

In my view, AI does not replace strong professionals. It raises the standard for them. The professionals who know how to combine technology with judgment, experience, and client understanding will be the ones who create the most value. At this point, not using AI (responsibly) is almost a disservice to the client, because it can help us work faster, think more clearly, and spend more time on the areas where human judgment matters most.

5. What should clients look for in a CPA when their tax situation involves multiple countries, foreign reporting, or complex ownership structures?

Clients should look for a CPA who does not jump to conclusions too quickly. In cross-border tax, the facts matter too much, probably more than in almost any other area of tax. A small change in residency, ownership, entity classification, or source of income can completely change the answer. Before giving advice, the CPA should understand all the facts and asking the right questions because there are a lot of them.

The right CPA should also be comfortable saying, “We need to coordinate with the foreign advisor.” That is not a weakness in my view. That is the right approach. When multiple countries are involved, one advisor usually does not have the full answer alone. It’s almost impossible.

Clients should also look for a CPA who can explain complex tax issues in plain language. Tax is a very technical world, and in many ways, it is almost its own language. That is even more true in cross-border tax, where you may be dealing with multiple countries, different rules, treaty positions, foreign reporting, and different interpretations of the same facts.

A good CPA should be able to take that complexity and translate it into something the client can actually understand. When clients understand the facts, the risks, and the options, they can sleep better at night and make informed decisions instead of guessing or reacting after the fact.

When Tax Planning Starts Before the Problem

Ron’s perspective makes one point clear. Once the tax return is being prepared, many choices have already been made. At that stage, the CPA may be reporting what happened rather than shaping a better outcome.

That is why early conversations matter so much. Residency changes, foreign investments, U.S. real estate purchases, foreign-owned entities, and ownership structures can all create reporting requirements and penalties if handled too late. In cross-border tax, even small details can change the answer.

For CPAs, this creates a shift from deadline-based compliance to year-round advisory. Clients need to understand which decisions require tax guidance before they act, not after. Better questions, better education, and better timing can prevent expensive surprises.

AI can help tax professionals work faster, organize research, and explain complex rules more clearly. But in areas like international tax, judgment still matters most. The right CPA needs to understand the full fact pattern, coordinate with foreign advisors when needed, and translate technical issues into clear guidance clients can act on.
