What it means
Every pool of money that generates income faces the same fork in the road: distribute it or keep it. Accumulated income is the running total of everything that has taken the second path.
In a trust, the trustee may have power or an instruction to accumulate income instead of paying it to beneficiaries, often while those beneficiaries are young. The accumulated income usually becomes part of the trust capital after a period, which changes who is entitled to it and how it is taxed.
In an investment fund, accumulation works through the share class. An accumulating class rolls dividends and interest straight back into the fund, so the value per unit rises rather than cash arriving in an investor's account.
In a company, accumulated income is essentially another name for retained earnings, the profits kept back to finance growth, repay borrowings or build a buffer instead of being paid out as dividends. The choice between accumulating and distributing is one of the most consequential decisions a board makes.
The appeal of accumulation is compounding, because income that stays invested earns further income. The catch is that accumulation is not automatically tax free, and trusts in particular are often taxed at high rates on income they retain, so the after-tax figure is the one that actually accumulates.
In practice
Real-world examples.
Example
A grandparent sets up a trust for a six year old with instructions to accumulate all income until the child turns eighteen. Over twelve years the accumulated income becomes a significant part of the trust's value, and the trustee reports it separately from the original capital each year.
Example
A pension saver chooses the accumulating class of a global equity fund. No cash ever reaches her bank account, but the unit price reflects both capital growth and the income rolled up inside it, which suits her because she does not need the money yet.
Example
A profitable engineering firm keeps 80% of its post-tax profit each year to fund a new factory. Shareholders accept lower dividends because the accumulated income is visibly turning into productive assets rather than sitting idle.
Formula
Calculation
Accumulated income = opening accumulated income + income earned - expenses and tax - amounts distributed
With reinvestment, the balance grows as: accumulated income = annual retained income x [((1 + r) to the power n - 1) / r]
Take a trust holding a $600,000 portfolio yielding 4% a year, with annual trustee expenses of $3,000 and tax of $4,200 on the income. Assume the retained income is reinvested at 4%.
Gross income each year = $600,000 x 4% = $24,000
Less expenses and tax = $24,000 - $3,000 - $4,200 = $16,800 retained each year
Accumulation factor for 5 years at 4% = (1.04 to the power 5 - 1) / 0.04 = 5.4163
Accumulated income after 5 years = $16,800 x 5.4163 = $90,994
The trust has therefore built up roughly $90,994 of accumulated income, of which $84,000 is the five years of retained income and about $6,994 is the return earned on income that was reinvested along the way.Case study
Seen in the real world.
Merrivale Family Trust is a fictional arrangement invented for this illustrative example. Established with $600,000 of investments, its deed instructed the trustee to accumulate income while the two beneficiaries were at school and only begin distributions once the younger turned twenty-one.
For the first five years the trustee retained roughly $16,800 a year after costs and tax, and by reinvesting it built up close to $91,000 of accumulated income on top of the original capital. The trustee kept a separate record of accumulated income because the tax treatment of a later payment depends on whether it comes from income or capital.
When distributions eventually began, that record proved its worth. The beneficiaries received payments correctly characterised for tax, and the trustee could show precisely how much of the trust's growth came from accumulated income rather than from movements in the value of the underlying investments.
Watch out
Common mistakes.
- Assuming accumulated income escapes tax because nobody received it. Trusts and companies are generally taxed on income when it arises, whether or not it is paid out.
- Losing track of which part of a fund is accumulated income and which is original capital. The distinction drives both entitlements and tax treatment, and it is very hard to reconstruct years later.
- Confusing accumulated income with cash in the bank. Reinvested income is usually sitting in investments, so it may not be available to spend at short notice.
Questions
People also ask.
How is accumulated income different from capital gains?
Income comes from dividends, interest and rent, while gains come from selling an asset for more than it cost, and the two are usually taxed under different rules.
Does accumulated income in a trust become capital?
In many trusts it does after a set period or on a trustee decision, which permanently changes who is entitled to it.
Is accumulated income the same as retained earnings?
In a company context the two mean essentially the same thing, though retained earnings is the standard label used in published accounts.
