The IRS is ramping up scrutiny of high-net-worth individuals and businesses, increasing audit rates by over 50% for those earning above $10 million. Recent IRS initiatives backed by Inflation Reduction Act funding have intensified enforcement on wealthy taxpayers, large partnerships, real estate investors, and tech businesses. IRS agents are digging deeper during audits and expecting taxpayers to produce more documentation to support every position on their returns. To help clients navigate this environment, certified tax planners must take proactive steps to bolster documentation and audit readiness. Below are ten authoritative strategies, complete with industry examples, IRS policy references, and best practices, to prepare for the increased IRS focus on documentation.

When Your Client’s World Is Bigger Than the U.S.
A lot of client meetings still start with the same assumptions: W-2 in a U.S. state, mortgage nearby, a 401(k), maybe some RSUs, and a college-savings plan. Yet many of those “simple” clients now own an apartment in another country, freelance for a foreign company, or have parents wiring money from overseas. The tax code does not see those details as background color; it treats them as organizing facts. This is where citizenship, residency, and domicile quietly step onto center stage. For planners, the challenge is not memorizing every cross-border rule. It is knowing when a client is no longer “just domestic” and shifting your planning framework before you stumble into penalties, double taxation, or blown opportunities.
