Zakat on Overseas Bank Accounts: Exchange Rates, Frozen and Joint Accounts

Four questions only cross-border account holders face

Zakat on bank money is settled ground: 2.5% once the hawl completes and the nisab is met. But if your money sits in two or three countries, the general explanation leaves the real questions unanswered. Which exchange rate applies? What about an account you cannot access? Who pays on a joint account? Is withheld tax deducted?

This article is about those four. For the basics, see the zakat calculator and its methodology.

One: which exchange rate?

The rule: the rate on the day your hawl completes — not the day you deposited, and not a yearly average. Zakat attaches to wealth at its value when the obligation falls due.

In practice this means currency movement changes your zakat even when your balance does not. Hold £10,000 through a year in which sterling gains 8%, and your zakat rises 8% without a single pound being added.

So fix your hawl date and record it. Postponing the calculation "until things calm down" means computing on a different day's rate, and the difference belongs to the poor, not to you.

Two: the account you cannot touch

Not every account bearing your name is wealth in your hand. The test is your ability to dispose of it, not whether a statement shows your name:

Account state	Ruling	Why
Current or savings, withdrawable	Due now	Complete ownership and control
Frozen by court order or sanctions	Deferred until released	Ownership is incomplete — no disposal
Fixed deposit breakable with a penalty	Due on the net	Access exists, even at a cost
Rental deposit or held guarantee	Due on receipt	Expected, not possessed
Country you cannot transfer out of	Deferred until able	The ruling follows reality, not paperwork

Deferred is not waived. When the funds are released, the majority position is one year's zakat; some scholars require all elapsed years. For a large sum, ask a qualified scholar.

Three: joint accounts

A joint account is neither taxed twice nor skipped. Each holder pays on their own share, not the whole balance.

If you and your brother hold $40,000 equally, each of you counts $20,000, adds it to your other wealth, and then checks the nisab against that total. The common error is each looking at the full balance — believing themselves above the nisab when they are not, or assuming the other will cover it.

Four: withheld tax

Tax already deducted from the account is not your money and is not zakatable. Tax that will fall due later but has not been taken is a debt — deductible only once it is actually payable.

The general rule: deduct debts that are currently due, not future instalments. This month's loan payment comes off; next year's does not.

A fully worked example

Khalid lives in Britain with money in three countries. His hawl completes on 1 Ramadan:

Source	Balance	In USD on the day	Counted?
UK account	£9,000	$11,250	Yes
UAE account, joint with his brother	AED 60,000	$8,167 (his half)	Half only
Court-frozen account	$15,000	—	No
Tax due this month	−$1,400	−$1,400	Deducted

Zakatable base: 11,250 + 8,167 − 1,400 = $18,017

Nisab: 85 grams of gold. At $130 per gram that day, the threshold is $11,050 — which he exceeds.

Zakat due: 18,017 × 2.5% = $450.43

Note what the four questions changed. Without them Khalid would have counted $34,417 and paid $860 — nearly double what he owes, on money he cannot access and on his brother's share.

To check the figure against today's gold price, use the zakat calculator, and the currency converter for the conversions.

Frequently asked questions

Should I use my country of residence or the account's currency?

The ruling is the same either way; what matters is valuing everything on one day. Pick one currency — usually where you live — and convert everything at that day's rate. The point is not to mix rates from different days.

I have forgotten my hawl date. What now?

Make a reasoned estimate of when your wealth first reached the nisab, settle on a date you are comfortable with, and keep it. Choosing an earlier date is the more cautious course, since it discharges the obligation sooner.

Is zakat due on an account I have not used for years?

Yes, as long as withdrawal is possible. Neglect does not remove the obligation, and zakat is owed for each elapsed year. Where old balances cannot be reconstructed, estimate and err on the higher side.

What about a conventional account that pays interest?

Zakat is on the principal. Interest is not lawfully owned and is not zakatable — it should be disposed of to public benefit without seeking reward for it. It cannot be counted as zakat, because zakat must come from lawful wealth.
