What Are You Willing to Pay in Taxes This Year? How RIAs Set and Revise a Client's Tax Budget

The Client Who Cannot Answer the Budget Question 

A hypothetical RIA onboards a married couple with a $1.4 million taxable account. Most of it sits in appreciated stock they have held for years, and the firm plans to move them into a tax-managed model over several years. In the proposal meeting the advisor asks for the household's capital gains budget. The couple has never tracked one. One spouse says, "Whatever is reasonable," and the advisor enters a figure that looks sensible. 

Eight months later the couple sells a rental property, and their CPA reports a gain of roughly $90,000 on the sale. The transition is still selling legacy shares against the original budget, and the portfolio team has no record of the property sale. The household's tax bill for the year now includes the property gain on top of whatever the transition realized. 

This sequence turns on three decisions that sound administrative: 

• How the starting number is chosen: The advisor entered a figure that looked sensible, and nobody tied it to the household's other gains. 
• Whether anyone revises it: The property sale happened mid-year, and no step in the process asked the portfolio team to update the budget. 
• How long the number lasts: The original budget carries into later calendar years unless the advisor communicates a new one. 

In VAST, the budget sets how fast legacy positions are sold and how closely the account can track its model. A casual number keeps shaping the account long after the meeting where it was chosen. 

For a broader explanation of how tax-loss harvesting works and how harvested losses can fund a move into a model, the tax-loss harvesting guide covers the complete framework. This blog focuses on the client conversation and the mid-year revisions that guide cannot address in full depth.

Why a Tax Budget Set Once Goes Stale During the Year 

A budget is a forecast of how much gain a client can absorb in a calendar year. Several inputs to that forecast sit outside the account, so they can change while nothing in the account changes. 

The most common are: 

• Gains realized elsewhere: Vestmark's sample transition analysis assumes the full capital gain budget is available to the account and is not used elsewhere. A rental property sale, a business interest, or a partnership K-1 consumes capacity the account was counting on. 
• Loss carryforwards: The same analysis does not consider unused losses carried forward from earlier years. Whether the client has any changes how much gain they can realize at a given tax cost, so the question belongs in the budget conversation. 
• Changes in tax rates: Taxable income, filing status, and state of residence feed the personal federal and state rates VAST uses. A raise, a retirement, or a move to another state changes the rate, and with it how much gain the same dollars of tax will cover. 
• Estimates that drift: The transition tax impact shown on a proposal is a point-in-time estimate and may differ substantially from the year-end tax cost. Market moves change which lots carry gains between the proposal and December. 
• Gains already realized: Lowering a budget mid-year does not reverse gains the account has already realized. In VAST, gains realized year to date set a floor for the revised budget. 
• Carryover into the next year: An unrevised budget continues into the next calendar year, so an outdated figure can persist across tax years. 

None of these shows up in a proposal demo, where the budget is a field that gets filled in once. They appear after onboarding, when the client's situation moves and the account has to follow.

Five Scenarios That Show Whether a Tax Budget Works in Practice

Each question below is tied to a specific client moment instead of a general question about budget support, since the general version is easy for any vendor to answer with a yes. Each scenario pairs the moment with a mechanism-backed answer and an answer that signals the budget is a one-time entry.

Bring these into a live demonstration, where the follow-up detail matters as much as the first answer.

The Conversion Question Most RIAs Never Ask: From Tax Dollars to Gain Budget 

Most RIAs already ask whether a platform supports a capital gains budget. The answer is almost always yes, because most platforms accept some kind of limit. Far fewer ask what unit the limit is expressed in and how a client's tolerance becomes that unit. 

VAST starts with a question the client can answer: what are you willing to pay in taxes this calendar year? That amount is the Tax Reserve. The proposal workflow asks the advisor for the client's taxable income, filing status, and state, builds personal federal and state rates from them, and converts the reserve into a capital gains budget using those rates and the mix of short-term and long-term unrealized gains in the account. 

A simple case shows what the conversion does. Take an account whose unrealized gains are all long term, and a client who will set aside $30,000 for the year. The arithmetic below is illustrative and is not output from a Vestmark proposal. 

• At a combined long-term rate of 15%, $30,000 supports about $200,000 of gains 
• At 20%, it supports about $150,000 
• At 25%, it supports about $120,000 

The same dollars of tolerance produce a range of $80,000 in the gain budget. Short-term gains cost more per dollar than long-term gains, so an account holding many short-term lots supports a smaller budget from the same reserve. 

A platform that takes a gain figure or a flat percentage of account value leaves this arithmetic to the advisor, or skips it. Putting the question to a vendor directly shows which kind of platform it is: "If my client says they will pay $30,000 in tax this year, what gain amount does your platform allow, and which rates does it use?" 

Two answers tend to come back: 

• A platform that converts will describe turning the reserve into a gain budget using the client's own short-term and long-term rates and the account's gain mix. 
• A platform that does not will describe an advisor-entered gain figure or a percentage cap, which gives a client in a 15% bracket and a client in a 25% bracket the same limit. 

The proposal then lets the client see the tradeoff. For taxable accounts moving into a new model, VAST illustrates three scenarios at different tax costs based on the reserve, and pairs each with measures such as risk, tax cost, and a trading summary. A client who asks what another $10,000 of tax buys can be shown the answer on a page.

What to Ask Reference Clients About Setting and Revising Budgets 

A reference call about tax-managed investing in general will rarely surface how budgets are handled after onboarding. A call focused on mid-year changes will. Organize the conversation around four areas. 

Volume and Triggers 

• How many client budgets did the firm revise in the last tax year? 
• What prompted each revision? 

Revisions on Live Accounts 

• How was a revision handled on an account already in transition? 
• Was the account frozen, or did the transition plan have to be rebuilt? 

Outside Gains and CPA Coordination 

• Has the firm ever found out about a large gain outside the account after the budget was set, and how did it learn? 
• How do the advisor and the client's CPA agree on the budget each year, and where is that agreement recorded? 

Year-Start Confirmation 

• What does the firm do on January 1 to confirm each account's budget for the new year?

How Does a Tax Year Play Out When the Budget Is Managed or Left Alone?

Firms that treat the budget as a live input describe the year in a consistent way: 

• The client answers a dollar question at onboarding, and the advisor records expected gains and loss carryforwards outside the account 
• The budget is reviewed at the mid-year meeting and again in the fourth quarter, often alongside the CPA 
• A change in the client's situation leads to a revision on the live account, without rebuilding the setup 
• The advisor can show the client how much of the budget has been used and how much remains 

Firms that treat the budget as a one-time entry describe a different year: 

• The starting number is a guess made in the proposal meeting, and nobody connects it to the client's other gains 
• A property sale or a bonus year surfaces at tax time, after the account has already realized gains against the original budget 
• The transition runs slower than the client expected because the budget was set too low, or overshoots because it was set too high 
• The same figure carries into the next year because no one confirmed it on January 1

Three Things to Request Before You Commit to a Platform 

A Proposal Built for One of Your Own Cients

Ask the vendor to show the Tax Reserve entered in dollars, the personal rates built from the client's inputs, the resulting gain budget, and the scenarios at different tax costs. Use a client with a mix of short-term and long-term gains so the conversion is visible. 

A Walkthrough of a Mid-Year Revision on a Live Transition

Ask the vendor to lower and then raise a budget on an account in progress, and to show what changes, what stays in place, and how year-to-date realized gains affect the revised figure. 

Reference Clients Who Revised Budgets During a Tax Year

A reference whose clients' situations never changed cannot speak to how the platform behaves when one does.

RIA Evaluation Checklist: Setting and Revising a Client Tax Budget

Use the checklist below during vendor evaluation or an internal platform review to confirm that the tax budget is a live input and a one-time field. Each row describes a mechanism a firm should be able to see and verify.

A general assurance that the platform supports a capital gains budget does not meet any of these rows.

Explore Tax Budget Management with Vestmark 

For RIAs moving clients with appreciated holdings into a tax-managed model, the budget capability that matters is whether an advisor can start from the dollars a client will pay, convert them into a gain budget with the client's own rates, and revise that budget as the client's year unfolds. 

VAST accepts either a Tax Reserve or a capital gains budget, builds personal federal and state rates through the proposal workflow, illustrates scenarios at different tax costs, and allows the budget to be updated throughout the year. The original budget carries into later calendar years unless the advisor communicates a new one. Learn more about Vestmark's Investment Advisory solutions, or visit Vestmark's page for RIAs.

Key Takeaways 

• A client can usually say what they would pay in taxes this year, and can rarely say what their capital gains budget is. Starting the conversation with dollars of tax gives the advisor an answer to work from. 
• A Tax Reserve becomes a gain budget through the client's own short-term and long-term rates and the mix of gains in the account. The same $30,000 supports very different gain budgets at different rates. 
• Gains realized outside the account, loss carryforwards, and changes in income or state can make a budget outdated within the same year. 
• A budget revision should apply to the live account, reflect gains already realized, and leave the transition in place. 
• Unless the advisor communicates a new figure, the original VAST budget carries into later calendar years, so a January review of each account's budget belongs in the annual calendar. 
• Reference calls about mid-year budget changes reveal more than reference calls about tax-managed investing in general.
