How it is worked out
The published share of the qualified business income you enter, in full while your taxable income is at or below the published threshold. Above it, that amount is brought down towards the published wage and property ceiling - the greater of the published share of your W-2 wages, or the published share of those wages plus the published share of your unadjusted basis in qualified property - by the same share of the way your income has come through the published phase-in range, so the ceiling applies in full at the top of it and not at all below it. Where the ceiling is already the larger of the two, nothing is taken off. For a specified service trade or business the whole of it is scaled by what is left of that range, reaching nothing at the top. The answer is then never more than the published share of your taxable income less the net capital gain you enter, and it is rounded to the nearest cent. This computes one trade or business, or one aggregation: it carries no REIT or publicly traded partnership component, no patron reduction and no loss carried forward from an earlier year.
It uses QBI component rate, 20% and W-2 wage limit rate, 50% and Alternative W-2 wage rate, 25% and Qualified property rate, 2.5% and Taxable income limit rate, 20% and Threshold, joint filers, $403,500 and Phase-in range top, joint filers, $553,500, published above.
