A dividend reinvestment plan is one of the easiest good decisions an investor can make. You tick a box, the dividends stop landing in your bank account, and instead they quietly buy more shares twice a year without brokerage, without a decision to make, and without the temptation to spend the money.
Twenty years later that same tick box has produced something else: a holding made up of forty or more separate tax parcels, each with its own acquisition date and its own cost base, most of them for odd numbers of shares at prices you no longer have a record of.
The compounding was real, and the strategy usually worked. The paperwork is the part nobody warned you about, and it only becomes visible at the exact moment it is hardest to fix: when you go to sell.
This guide explains what a DRP does to your tax position, why the record keeping problem compounds alongside the investment, what it costs when the records are missing, and why 1 July 2027 turns a someday problem into something with a deadline attached.
What a DRP actually does to your tax position
You are taxed as though you took the cash
The starting point surprises a lot of people. Participating in a DRP does not defer or reduce the tax on your dividends. For tax purposes you are treated as having received the dividend in cash and then having used that cash to buy more shares.
So the dividend is assessable income in the year it is paid, grossed up for franking credits in the usual way, with the franking credits available as an offset. Reinvesting changes nothing about that. Our guide on maximising your wealth with franking credits covers how the imputation side works.
The cost base is the cash applied, not the grossed-up dividend
Here is the detail that catches even careful investors. The cost base of the new shares is the amount of the dividend actually applied under the plan, which is the cash component. It does not include the franking credit, because no franking credit was applied to buy shares.
If a $360 fully franked dividend is reinvested and you receive 45 shares, the cost base of those 45 shares is $360, and their acquisition date is the date they were allotted. The associated franking credit was an offset against your income tax, not part of what you paid for the shares. Investors who add the grossed-up figure to their cost base are overstating it, which is an error in the other direction and just as reviewable.
Every allocation is a separate parcel
Each DRP allocation creates a fresh CGT parcel with its own acquisition date, its own cost base and its own twelve month clock. This is the mechanical root of the whole problem. Two dividends a year for twenty years is forty parcels of a single holding, on top of whatever you originally bought.
That matters because when you sell part of the holding, you have a genuine choice about which parcels are treated as sold, and that choice changes your tax bill materially. Our guide on which parcel to sell and why first in, first out is only a fallback works through that decision. You cannot make that choice without parcel records, which is precisely what long term DRP participants tend not to have.
The phantom income problem
Before the record keeping issue, there is a cash flow one. You owe tax on a dividend you never received in cash.
For a modest holding this is trivial. For someone with a substantial portfolio fully reinvested, it is not. A $30,000 franked dividend income stream, entirely reinvested, still produces an assessable amount that has to be funded from somewhere, and the franking credits will usually only cover part of it if you are on a marginal rate above 30 per cent.
This is the single most common reason investors switch DRPs off as their portfolio grows. It is not that reinvesting stops being sensible. It is that the tax has to be paid in cash and the strategy stops producing any.
What missing records actually cost
Consider an investor who bought 2,000 shares in a major listed company in 2005 at $25.00, a cost of $50,000, and has run the DRP ever since. Over twenty years the plan has added 1,180 shares, with a total of $58,400 of dividends reinvested. The holding is now 3,180 shares at $58.00, worth $184,440. Assume a marginal rate of 39 per cent including the Medicare levy, and a sale before 1 July 2027.
| With complete DRP records | Without DRP records | |
|---|---|---|
| Proceeds | $184,440 | $184,440 |
| Cost base | $108,400 | $50,000 |
| Capital gain | $76,040 | $134,440 |
| Taxable after discount | $38,020 | $67,220 |
| Tax at 39% | $14,828 | $26,216 |
The difference is $11,388, and it is pure record keeping. The investor already paid income tax on every one of those reinvested dividends as they were received. Without the records to prove the cost base, that same money is taxed a second time as a capital gain.
The ATO’s position is that the burden of substantiating a cost base sits with the taxpayer. A holding statement showing 3,180 shares tells you what you own. It does not tell you what you paid.
Why the problem compounds
Several things conspire to make DRP records harder to reconstruct than ordinary purchase records.
- Odd allocations and residuals. DRPs allocate whole shares, and the leftover cents are carried forward as a residual balance in the plan and applied to the next dividend. Reconstructing a parcel history without accounting for residuals produces figures that do not reconcile.
- DRP discounts. Some companies allocate shares at a discount to the volume weighted average price. Your cost base is the amount actually applied, not the market price on the day, so a market price series is not a substitute for allocation statements.
- Registry changes. Companies move between registries, registries merge and rebrand, and online portals typically show only recent history. Twenty year old allocation statements are frequently not retrievable from the current portal.
- Corporate actions. Share splits, consolidations, demergers, returns of capital and takeovers all adjust cost bases, sometimes across every parcel simultaneously. A demerger apportionment applied to forty parcels is forty separate adjustments.
- Time. The whole point of a DRP is that it runs without attention. Twenty years of not thinking about something is twenty years of not filing anything.
There is also an inheritance dimension. Where post-CGT shares pass to a beneficiary, the beneficiary generally takes on the deceased’s cost base and acquisition date. So an incomplete DRP history does not resolve on death. It transfers, along with the shares, to whoever has to deal with it next. Executors regularly discover this at the worst possible time, and it is one of the practical burdens covered in our guide on what the executor role actually involves.
A DRP and a bonus share plan are not the same thing
This distinction matters and is routinely missed, including by investors who have participated in both.
Under a dividend reinvestment plan, a dividend is declared and paid, it is assessable to you, and it is applied to acquire new shares. Those shares have a new acquisition date and a cost base equal to the amount applied.
Under a bonus share plan, where no amount is assessed to you as a dividend, the treatment is different. The bonus shares are generally taken to have been acquired at the same time as the original shares they relate to, and the cost base of the original parcel is spread across the original and bonus shares together. That reduces the cost base per share of your existing holding rather than creating a new parcel with its own cost.
The practical consequences are significant. Where the original shares were acquired before 20 September 1985, bonus shares issued in respect of them can inherit that pre-CGT status. Where they were acquired after that date, the apportionment quietly reduces the cost base of shares you already held. Neither outcome resembles DRP treatment, and applying DRP logic to a bonus share plan history produces the wrong answer in both directions.
Some Australian listed investment companies have historically offered both. If your holding predates the mid-2000s, check which plan you were actually in before you reconstruct anything.
Why 1 July 2027 puts a deadline on this
The replacement of the 50 per cent CGT discount is now law. From 1 July 2027, for individuals, trusts and partnerships, the discount gives way to cost base indexation plus a minimum 30 per cent tax rate on real capital gains.
The transitional mechanism is the part that matters here. Every CGT asset held at 30 June 2027 is deemed to be sold and immediately reacquired just before 1 July 2027. The gain accrued up to that point keeps the old 50 per cent discount and is deferred until you actually sell. Growth after that date falls under the new rules.
Read that back with a forty parcel DRP holding in mind. The deemed sale applies parcel by parcel. To work out the pre-reform gain attaching to each parcel, and therefore to access the deferred 50 per cent discount on it, you need that parcel’s cost base. If you cannot establish it, you cannot establish the pre-reform component that carries the more favourable treatment.
Put plainly, the value of your DRP records is about to increase, and the window to reconstruct them closes at the same time. Registries do not get better at producing twenty year old statements, and the reconstruction is far easier done now than after a deemed sale has already run through the holding. Our guide to CGT aware rebalancing before 30 June 2027 covers the broader timing questions, and the short version there applies here too: this is a reason to get organised, not a reason to sell in a hurry.
How to reconstruct a DRP history
It is usually possible, and it is usually tedious. Work through these in order.
- The registry portal. Log in to whichever registry holds the shareholding and download everything available, including transaction histories and any annual CGT or cost base reports. These reports are a useful starting point but are not always complete across registry changes, so treat them as evidence rather than as the answer.
- Annual dividend and tax statements. These show the dividend amount, the DRP allocation, the number of shares issued and the allocation price. This is the single most useful document, and the one people most often still have in a filing cabinet.
- Your old tax returns. Dividend income declared in a given year confirms the amount reinvested that year even where the allocation statement is gone. Your accountant may hold workpapers going back further than you do.
- Company announcements. Listed companies announce DRP allocation prices to the ASX for each dividend. Where you know the number of shares allotted but not the price, or the reverse, the announcement fills the gap.
- Corporate action documentation. Demerger and scheme booklets set out the cost base apportionment percentages, and the ATO publishes class rulings for most significant corporate actions.
Once assembled, put it in one register with a row per parcel showing date, quantity, amount applied, cumulative holding and any corporate action adjustments. That register is the asset. Keep it somewhere your executor can find it.
Should you keep the DRP running?
None of the above is an argument against reinvesting. Automatic reinvestment is one of the most reliable wealth building habits available, it removes brokerage, and it takes the decision away from you at exactly the moments you are most likely to make a poor one. The mathematics is set out in our guide on the power of compounding.
The honest case against is that a DRP reinvests into whatever you already own, which means it makes concentrated holdings more concentrated. A DRP on a bank stock that has grown to 18 per cent of your portfolio keeps buying more of that bank stock. It is the opposite of rebalancing, which is why our guide on when to rebalance your portfolio and this one should be read together.
There is a middle path that suits a lot of investors from mid career onwards. Turn the DRP off, let dividends accumulate in a cash account, and deploy that cash deliberately once or twice a year into whatever is underweight. You keep almost all of the compounding, you gain a rebalancing mechanism, you have cash available to pay the tax on the dividends, and you create one parcel a year instead of two per holding. The cost is a small amount of brokerage and a decision you now have to make.
In retirement the calculus shifts again, because dividends become income you actually want to receive rather than capital you want to compound. Our guides on how investment strategy changes in retirement and whether to draw income from super or investments first cover that transition. The broader question of income versus growth is dealt with in dividend investing versus growth investing.
Two situations that work differently
Inside superannuation
Dividends reinvested inside a super fund are fund earnings, not contributions, so they do not count against your contribution caps. The fund still creates parcels and still needs cost base records, but that is the trustee’s or administrator’s job and it is generally handled properly by fund accounting software. This is one genuine argument for holding dividend heavy Australian equities inside super rather than personally, alongside the tax rate difference discussed in our guide on off market transfers of shares into super or a trust.
ETFs and managed funds
Distribution reinvestment plans on ETFs work on the same principle, but with an extra layer. Attribution managed investment trusts make annual cost base adjustments, upward or downward, based on the components of the distribution, and those adjustments have to be applied across your parcels. Your annual attribution statement carries the figures. Practically, an ETF held for fifteen years with distribution reinvestment on generates one of the more complex CGT positions a retail investor can hold. Our comparison of ETFs versus individual shares covers the structural differences.
Where Professional Advice Adds Value
DRP record keeping is not glamorous and it is not something most people will do voluntarily. It is also one of the few areas of financial planning where the value can be stated as a number, because the difference between complete and incomplete records is measurable in tax paid.
At Money Path the work usually involves three things. First, establishing what you actually hold and in which plan, because the DRP and bonus share plan distinction changes the whole calculation. Second, coordinating the reconstruction with your accountant and the registries while it is still feasible, particularly ahead of the 2027 transition. Third, deciding whether the DRP should keep running at all, which is a portfolio construction question about concentration and cash flow rather than a tax question.
Reasonably often the third one is the conversation that matters most. A client with three quarters of their Australian equity exposure in four banks, all with DRPs running, has a concentration problem that the tax tail should not be allowed to wag. Getting the records in order is what makes it possible to fix that efficiently rather than expensively.
Frequently asked questions
Do I pay tax on dividends I reinvest through a DRP?
Yes. You are treated as having received the dividend in cash and then used it to buy shares, so the dividend is assessable income in the year it is paid, grossed up for franking credits in the normal way. Reinvesting does not defer or reduce the income tax.
What is the cost base of shares I receive under a DRP?
The amount of the dividend actually applied to acquire them, which is the cash component, plus any incidental costs. It does not include the franking credit. The acquisition date is the date the shares were allotted under the plan, not the ex-dividend date.
What happens if I cannot find my DRP records?
You may be unable to substantiate the cost base of those parcels, which means you could be taxed on a larger capital gain than you actually made, effectively paying tax twice on the reinvested dividends. Reconstruct from registry statements, annual tax statements, old tax returns and ASX announcements of DRP allocation prices before you sell.
Is a bonus share plan the same as a DRP?
No. Under a bonus share plan where no amount is assessed as a dividend, the bonus shares are generally taken to have been acquired at the same time as the original shares, and the cost base of the original parcel is spread across both. That is a different outcome to a DRP, which creates a new parcel with its own date and cost.
Should I turn my DRP off?
It depends on your stage and your concentration. Reinvesting suits accumulation, but it keeps buying more of what you already own, which works against rebalancing, produces tax with no cash to pay it, and creates parcels. Many investors from mid career onwards take dividends in cash and reinvest deliberately once or twice a year instead.
How do DRPs affect the CGT changes from 1 July 2027?
Assets held at 30 June 2027 are deemed sold and reacquired, parcel by parcel, with the gain accrued to that date keeping the 50 per cent discount and deferring until you actually sell. Working out that pre-reform component for each DRP parcel requires its cost base, so incomplete records become more costly through the transition, not less.
Do DRP records matter if I never intend to sell?
Yes. Post-CGT shares generally pass to beneficiaries with the deceased’s cost base and acquisition date intact, so the record keeping problem is inherited along with the shares. Leaving a complete CGT register is one of the more useful things you can do for an executor.
Taking the next step
If you have had a DRP running for a decade or more, the useful action is not a decision about whether to sell. It is an afternoon spent finding out whether you can actually prove what you paid. That question is much cheaper to answer now than in the year you need the answer.
