Ratepension or taxable account? The tax comparison most people get wrong
The deduction is not a gift — it is a deferral. Here is the calculation that actually decides the choice
Ratepension, aldersopsparing, the stock savings account and a taxable account compared on end wealth after all Danish taxes. The deduction is deferred tax — what matters is PAL tax vs. stock income tax and the pension supplement effect.
“Contribute to your pension — everything is tax deductible.” That is the advice from the bank, the pension provider and most personal finance guides. It is not wrong. But it is only half the truth.
The most persistent misunderstanding about pensions
The misunderstanding goes roughly like this: the deduction makes pension contributions a good deal because the state pays part of your savings.
The state does not pay. The state waits.
The deduction means you pay no income tax on the amount you contribute to a ratepension (instalment pension) or livrente (annuity). But when the money is paid out in retirement, it is taxed as personal income — typically 37–38% for a retiree in the bottom bracket, more if the payouts are large. The deduction is not saved tax. It is deferred tax.
That does not make pensions a bad idea. It means the deduction by itself is not the argument. What actually decides whether ratepension beats a taxable account is three other things:
- The ongoing tax on returns during the savings phase: PAL tax (the Danish pension return tax) of 15.3% in pension accounts versus 17% in the stock savings account and 27–42% stock income tax in a taxable account
- The difference between your marginal tax rate now and in retirement — the value of the deduction against the taxation of the payout
- The pension supplement effect: payouts from ratepension and livrente reduce the means-tested pensionstillæg (the income supplement to the Danish state pension) by 30.9% inside the reduction zone
The three effects pull in different directions. The rest of this article adds them up.
What the deduction actually gives (and takes) — the calculation
Let us put numbers on it with one monthly amount and two routes.
You set aside DKK 1,000 of your salary for savings. The AM-bidrag (labour market contribution, 8% of salary) has been paid in both cases — it is withheld at contribution, either on the salary or by the pension provider for employer schemes, and it never returns at payout. So we count in kroner after AM-bidrag.
Route 1 — ratepension: The full DKK 1,000 goes into the account, because the deduction cancels the income tax now. At payout you pay, say, 37%. Of every DKK 1,000 plus returns, you end up with 63% in hand.
Route 2 — free savings: You pay 37% tax first and invest DKK 630. At payout there is no further tax on the principal (only on the returns along the way).
Note the symmetry: and are the same number. Whether the tax is paid before or after the growth is mathematically irrelevant, as long as the rate is the same. The deduction gives you nothing — and costs you nothing — if your marginal rate is identical at contribution and at payout.
What remains is what genuinely separates the account types: how hard the returns are taxed along the way, and what the payout does to your pension supplement.
The right comparison: end wealth after all taxes
Here is the calculation for DKK 3,000 of salary every month (after AM-bidrag) for 25 years at a 7% annual return before tax. The marginal tax at contribution is 37% in all scenarios — so the free accounts invest DKK 1,890 after tax, while the ratepension receives the full amount via the deduction.
| Account type | Tax on returns | Tax at payout | End wealth |
|---|---|---|---|
| Aldersopsparing | 15.3% (PAL) | None | DKK 1,305,000 |
| Ratepension — payout at 37% | 15.3% (PAL) | 37% | DKK 1,305,000 |
| Stock savings account (ASK) | 17% | None | DKK 1,282,000 |
| Taxable account, individual shares | 0% ongoing | 27% of gain at sale | DKK 1,274,000 |
| Ratepension — payout at 42% | 15.3% (PAL) | 42% | DKK 1,201,000 |
| Taxable account, ETF (mark-to-market) | 27% | No further tax | DKK 1,155,000 |
| Ratepension — in the pension supplement zone | 15.3% (PAL) | ~56% effective | DKK 902,000 |
A few things stand out.
Aldersopsparing and ratepension at 37% are identical to the last krone. That is the symmetry from the previous section: same tax on returns (PAL), same effective taxation of the contribution — just on opposite sides of the growth.
Ratepension spans from the top to the bottom of the table depending on a single variable: the tax at payout. At 37% it is best in the field. Inside the pension supplement’s reduction zone — where every krone paid out is both taxed at roughly 37% and reduces the supplement by 30.9% — the effective rate is about 56%, and ratepension becomes the most expensive choice in the table by a clear margin. The mechanics are covered in The pension supplement trap.
Assumptions worth knowing: The aldersopsparing ceiling of DKK 9,900/year (2026) means DKK 3,000/month cannot actually be placed there alone — the row shows the account type’s tax profile, not a realistic single scenario. The stock savings account’s deposit ceiling of DKK 174,200 (2026) is also hit along the way. The individual-shares row assumes the sale is spread over several years so the gain stays below the progression threshold of DKK 79,400 (2026) — sell everything at once and most of it is taxed at 42%. And 7% returns for 25 years is an assumption, not a prediction.
Compare the account types yourself
The bars show end wealth after all taxes for the same monthly amount of salary, across the account types from the table — sorted with the highest on top. You can adjust the monthly amount, the number of years, the expected return and your marginal tax at contribution, and watch the ranking shift.
Try dragging the marginal tax at contribution up to 52%. The ratepension bars move towards the top, because the deduction is now worth more than the payout tax costs. That is the whole logic in one movement: ratepension is a bet that your tax rate is higher now than it will be in retirement.
When ratepension actually wins
Ratepension is the right choice when three conditions hold at the same time:
1. You pay top or middle bracket tax now. From 2026 that means personal income above roughly DKK 641,200 after AM-bidrag (middle bracket, 7.5 percentage points extra) or DKK 777,900 (top bracket, a further 7.5 percentage points). The deduction value of a pension contribution rises accordingly — up to about 52% against the 37–38% in the bottom bracket.
2. You expect to be taxed lower as a retiree. That is the case for most people: the payouts are smaller than the salary was, and retirees pay no AM-bidrag. If you pay 52% now and 37% later, those 15 percentage points are a real, permanent gain — on top of the low PAL tax.
3. Your total pension payouts keep you outside the pension supplement’s reduction zone. Either below the threshold of DKK 99,200/year in other income (2026, single retirees) — or so far above DKK 438,200 that the supplement is gone anyway and the marginal rate is back to normal.
Two reinforcements come on top. The extra pension deduction (ekstra pensionsfradrag) gives an additional allowance of 12% of deductible pension contributions up to DKK 87,800 (2026) — 32% if you are 15 years or less from state pension age. It improves the ratepension case by a few percentage points, most for those close to retirement. And the deduction ceiling of DKK 68,700 (2026) only applies to ratepension and terminating annuities — lifelong annuities (livrente) have no ceiling when contributions go via an employer.
Conversely: if you pay bottom bracket tax now and expect to land in the reduction zone as a retiree — which hits many people with an ordinary occupational pension — the conditions are turned upside down. You get 37% in deduction value now and pay ~56% effective tax later.
Aldersopsparing: the underrated account
The aldersopsparing rarely makes headlines, but its tax profile is hard to beat:
- PAL tax of 15.3% on returns — the lowest ongoing rate of any account type
- No tax at payout — the money is yours
- No pension supplement effect — the payout does not count in the means test
It combines the pension account’s low tax on returns with the taxable account’s payout freedom — without the deduction’s bet on future tax rates and without pushing you into the reduction zone.
The price is the ceiling. In 2026 you can contribute DKK 9,900 per year. If you are 7 years or less from state pension age, the limit rises to DKK 64,200 per year. Contribute too much (with more than 7 years to pension age) and the excess is charged a 20% penalty.
DKK 9,900 a year does not sound like much. But DKK 825 a month for 25 years at a 7% return grows to around DKK 570,000 after PAL tax — tax-free at payout and invisible to the pension supplement. As the first priority in a savings order, it is hard to argue against.
A practical savings order
The rules above can be condensed into a typical priority list for a private saver. It does not fit every situation, but it is a sensible starting point:
- Employer match first. If your employer matches pension contributions, that is a return you cannot get anywhere else — take it, regardless of account type.
- Aldersopsparing up to the ceiling. DKK 9,900/year (DKK 64,200 within 7 years of pension age). Best tax profile in the field.
- Stock savings account up to the ceiling. 17% mark-to-market tax and no pension supplement effect. The ceiling is DKK 174,200 (2026). See the ASK guide.
- Ratepension — if you pay top or middle bracket tax. The deduction value needs to be clearly higher than your expected payout tax before the bet is good. Keep an eye on where your total payouts land relative to the reduction zone.
- Taxable account for the rest. Prefer realisation-taxed individual shares or distributing index funds over mark-to-market ETFs if you want tax deferral working for you — see the stock taxation guide.
Note what the order does not say: it does not say “maximise ratepension because the deduction is large”. The size of the deduction is not the argument. The relationship between your tax now and your tax in retirement is.
The overview: Pensionsinfo and Portfolio Manager
The whole calculation depends on numbers most people have never gathered in one place: what you expect in pension payouts, and what your free savings actually produce.
For the pension side, Pensionsinfo.dk is the starting point. It collects your schemes across pension providers and shows the expected payouts — the number you need to hold up against the reduction zone’s thresholds.
For the investment side, Portfolio Manager is a Danish tool that gathers your accounts in one picture — stock savings account, taxable accounts, certain pension accounts and more — with correct average cost basis (GAK) and Danish taxes built in. It does not know the pension supplement rules yet, so the account type choice itself is still yours to work through — for instance with the component above. But it gives you the precise picture of what your savings are actually worth after tax, which the comparison requires.
This article explains the rules and the calculations — not what you personally should do. The rates apply to 2026 and are adjusted annually, and your situation depends on your specific income, schemes and pension age. Consider talking to an independent pension adviser before moving larger amounts between account types.
