He Spent $10,000 Turning His Black Belt Into a Second Career. The IRS Called It a New Profession, Not a Deduction.

A Second Act on the Mat

Picture a 64-year-old who has trained in martial arts for decades. He claimed Social Security at 62, but retirement never quite suited him. Now he wants to turn his black belt into a business of his own. Before opening the school, he spends roughly $10,000 on advanced instruction and an instructor certification. He views the money as an investment in the business. The IRS sees a line between improving skills in work he already performs and learning what he needs to enter a new profession.

That line may cost him the deduction.

When Training Becomes Personal

Work-related education can generally be deducted when it maintains or improves skills used in an existing trade or business. A working martial arts instructor who takes advanced courses to sharpen his teaching may qualify. Our longtime hobbyist starts from a different place. If the certification prepares him to teach professionally for the first time, the IRS can treat it as education that qualifies him for a new trade or business. Those costs generally remain personal and nondeductible, even if the training leads directly to paying students.

The black belt proves he knows the art. It does not necessarily prove he was already in the business of teaching it. Startup costs belong in another bucket. A business plan, market research, opening advertising and certain other expenses incurred while preparing the school may qualify for a limited deduction or be spread across future tax years once the business begins. Calling the instructor training a startup expense, however, does not automatically move it past the education rule.

Social Security Counts What the School Keeps

Once the first students bow onto the mat and begin paying tuition, the retirement question changes. Social Security looks at the school’s net profit, not every dollar that passes through the register. Rent, equipment, insurance, advertising and other legitimate business expenses come out first. What remains is generally subject to self-employment tax and enters his earnings history.

Because he claimed before full retirement age (FRA), that profit also falls under the retirement earnings test. In 2026, someone below that age for the entire year can earn $24,480 before Social Security begins withholding $1 in benefits for every $2 above the limit. The withheld benefits are not gone forever. His monthly amount is adjusted later to account for the months he did not receive checks.

There may be an upside as well. A strong year from the school could replace a weaker one in the earnings history used to calculate his benefit. The same profit that holds back checks today may add something to his monthly payment later.

Before He Pays for the Next Belt

Two records will help keep the tax picture straight.

1. Document when teaching became paid work. Prior students, contracts, income records and business filings can help show whether later education improved an existing profession or opened a new one.
2. Keep training, startup and operating expenses separate. They may all feel like costs of opening the school, but the IRS does not send them through the same door.

The $10,000 may not buy him a deduction, but that does not make the school a poor second act. Once the doors open, legitimate expenses can offset income, profitable years can strengthen his retirement record and decades spent on the mat can finally become work of his own.
