Stock Purification Guide: How to Calculate Tazkiyah on Dividends
A stock can pass Shariah screening and still have a small amount of non-permissible income. Large public companies may earn incidental interest on cash balances, receive income from a non-compliant subsidiary, or report another minor revenue stream that is not halal. Under AAOIFI-style screening, this does not automatically make the stock non-compliant when the impermissible income remains below the accepted threshold, but the shareholder should purify their share of that income by donating it to charity.
This process is called purification, tazkiyah, or tatheer. It is not the same as zakat, and it is not a fee paid to Halalytic or to an investment platform. It is a separate donation intended to remove the impermissible portion of investment income.
Why Purification Exists in Halal Stock Investing
When you buy a share, you own a proportional claim on the business. If the company earns a small amount from interest or another non-permissible source, part of the shareholder return is tied to that income. Purification handles this practical reality: the investor avoids intentionally benefiting from the haram portion while still being able to invest in companies whose main business and financial ratios pass Shariah screens.
The screening step and purification step answer different questions. Screening asks whether the company is investable at all. Purification asks what amount, if any, should be donated after receiving income from a company that passed screening.
The Basic Purification Formula
For most individual investors, the practical formula is:
Purification amount = dividend income x non-permissible income ratio
If a company paid you $500 in dividends and its non-permissible income ratio is 2%, you would donate $10 as purification. The remaining $490 is treated as permissible dividend income, assuming the company otherwise passed your Shariah screening methodology.
A Step-by-Step Example
| Step | Input | Result |
|---|---|---|
| Dividends received | $500 | Your gross dividend income |
| Purification ratio | 2% | Non-permissible income divided by total revenue |
| Amount to donate | $500 x 2% | $10 purification donation |
Halalytic's halal stock screener shows the screening status and available purification data so you can record the ratio alongside each holding.
Purification Is Not Zakat
Zakat is an obligation on qualifying wealth once your zakatable assets exceed nisab and the hawl condition applies. Purification is a donation of the impermissible portion of income from a mixed company. Paying one does not remove the other.
A Muslim investor may need to do both in the same year: donate the purification amount from dividends, then calculate zakat on the value of cash, stocks, funds, gold, crypto, and other zakatable assets. Halalytic's stock zakat calculator helps with the zakat side of that workflow.
What About Capital Gains?
Scholars and screening providers differ on how they treat capital gains. Some focus purification on dividends because dividends are a direct distribution of company income. Others calculate a per-share purification amount or apply a broader method that may include gains realized while holding the stock. If your Shariah advisor, fund, or screening provider gives a specific method, follow that method consistently.
The practical point is recordkeeping. Track your purchase dates, sale dates, dividends, purification ratios, and donations. If a stock later fails screening, keep a separate note for any income received while it was non-compliant and ask a qualified scholar how to handle the disposal or purification.
Common Mistakes to Avoid
- Counting purification as zakat. Purification is not paid to eligible zakat recipients as your zakat obligation. It is a separate cleansing donation.
- Ignoring dividend reinvestment. Reinvested dividends are still dividends. Include them when calculating the purification amount.
- Using stale screening data. Company financials change. Re-screen holdings periodically instead of relying on an old status.
- Purifying a stock that failed the business screen. Purification is not a workaround for companies whose core business is haram.
- Forgetting records. Keep a simple spreadsheet or note with dividend income, purification ratio, donation amount, and date donated.
A Simple Annual Workflow
- Export your annual dividend report from your brokerage.
- Re-screen each stock or ETF with your chosen Shariah methodology.
- Record the non-permissible income ratio for each holding.
- Multiply dividend income by the relevant ratio.
- Donate the total purification amount to charity.
- Keep the receipt and calculation notes with your tax records.
- Separately calculate zakat on your stock portfolio and other zakatable assets.
If you hold multiple stocks, compare them side-by-side with the halal stock comparison tool. Comparing status, ratios, and purification information in one view makes it easier to decide which positions need follow-up.
