Pension plan tax withdrawal simulator
Simulate your accumulated balance, income baseline, and compare single lump-sum tax vs staggered multi-year withdrawal tax savings.
The fundamental difference: Earned income vs. Savings income
When you invest in an index fund or ETF, capital gains are taxed under savings income rates upon redemption (typically between 19% and 28% only on net gains). Fund transfers are tax-deferred.
A pension plan works entirely differently. Upon withdrawal, you are not taxed solely on capital gains; 100% of the withdrawn amount (contributions plus gains) is treated as earned income (rendimientos del trabajo) under general progressive IRPF tax rates.
- Index funds & ETFs: Taxed only on capital gains at savings rates (19% to 28%).
- Pension plans: Taxed on 100% of withdrawn capital as earned income (up to 47%+).
- Transfers: Tax-free between index funds, but subject to income tax upon final pension retrieval.
Tax deferral vs. Tax exemption
Pension contributions reduce your taxable income today (up to legal annual caps). However, this mechanism defers income tax rather than exempting it.
When withdrawing funds in retirement, you repay that deferred tax at your future marginal earned income tax rate.
The lump-sum trap
Withdrawing your entire pension pot in a single tax year pushes your annual income into top marginal tax brackets, consuming thousands in unnecessary income tax.
Spreading withdrawals across multiple years maintains lower marginal tax rates, preserving more of your accumulated wealth.
This same logic applies outside pension accounts. If you also hold large unrealized capital gains in a taxable brokerage (stocks, ETFs, company shares), liquidating those in the same year as a big pension withdrawal compounds the bracket-jump problem. In those situations, pledging your securities — borrowing against the portfolio without selling — can unlock liquidity without triggering a capital gains realization that would otherwise ruin your staggered-withdrawal plan.
