Exemption for Roth individual retirement accounts
Roth contributions are taxed now, and all later earnings are untaxed forever.
JCT line: "Individual retirement arrangements: Roth IRAs". Unlike the other retirement items this is a genuine exemption rather than a deferral, so the cost never reverses.
The benefit is untaxed investment growth, so it scales with both the amount contributed and the return earned on it, over decades. Conversion rules allow large balances to be moved in without an income limit, which is where the largest accounts originate.
Structural reading
The only retirement item here that is an exemption rather than a deferral, which makes it categorically different from the much larger figures above it. A deferral postpones revenue; this forgoes it permanently, and the amount forgone grows with the return earned inside the account. The structural feature worth noticing is the conversion route: direct contributions are capped by income, but conversions are not, so the households excluded from the front door were given a side entrance in 2006. That is a distribution decision made through a technical rule rather than through the eligibility limit that appears to govern the provision.
Who gets it
The channels the benefit actually flows through, described by asset position, entity form and form of return. Never by named individuals.
Cost split by the concentration score. That score is a judgement rather than a published figure, so treat this as the scale of the split, not an audited allocation.
- Long-horizon holders of appreciating assets
Because earnings are never taxed rather than merely deferred, the benefit compounds with time and return. An asset that multiplies inside a Roth escapes tax on the entire gain.
- Conversions from pre-tax accounts
Converting a traditional balance to a Roth is not subject to the income limits that apply to contributions, which allows large balances to enter the untaxed structure by a route unavailable to ordinary contributions.
- Holders of assets contributed at low valuation
Where a contributed asset is worth little at contribution and a great deal later, the entire appreciation is permanently exempt.
Who pays
Taxpayers generally. Unlike a deferral, the forgone revenue is never recovered.
This transfer follows a general pattern, asymmetric organisation, sustained expert attention, and scheduled expiry dates.
